Phylogeny of Grumichellini Morse, 1981 (Trichoptera: Leptoceridae) with the description of a new genus from southeastern Peru

Osflintia manu, new genus, new species, of long-horned caddisfly (Leptoceridae: Triplectidinae: Grumichellini) is described and illustrated from southeastern Peru. The phylogeny of Grumichellini Morse (Leptoceridae: Triplectidinae) is revisited and hypotheses of homology of some morphological characters are reconsidered. The monophyly of the tribe is corroborated and the phylogenetic relationships of its included genera are inferred to be (Triplexa (Gracilipsodes ((Grumichella, Amazonatolica) (Atanatolica, Osflintia, n. gen.)))) from adult and larval characters. Diagnostic characters of the new genus include the following: reduced tibial spur formula (2, 2, 2), loss of forewing crossvein sc-r1, hind wing discoidal cell closed, hind wing fork IV present, pair of long setae on tergum IX of the male genitalia, and pair of processes on the apex of segment X.     

New fan worm genera and species (Polychaeta, Sabellidae, Fabriciinae) from the western Pacific, and cladistic relationships among genera

Five new species are described from among the genera Fabriciola Friedrich, 1939 (one species from Okinawa), Novafabricia Fitzhugh, 1990 (two species from Australia and Papua New Guinea, respectively), and two new monotypic genera, Brifacia gen. n. (Australia), and Pseudoaugeneriella gen. n. (Okinawa). All species are known only from the intertidal. Fabriciola rubra sp. n. is a member of the species complex with red peristomial and pygidial eyes, inferior thoracic flagellate setae, and abdominal pin-head setae. Novafabricia labrus sp. n., and N. exiguus sp. n., are distinguished from other species based on the distribution of inferior thoracic pseudospatulate setae. Brifacia metastellaris sp. n., resembles Fabricia stellaris (Müller, 1774) with regard to anterior peristomial ring collar construction and distribution of pseudospatulate setae, but differs in having abdominal uncini with relatively short manubria. Pseudoaugeneriella unirama sp. n., most closely resembles species of Augeneriella Banse, 1956 in general form, but has unbranched vascularized ventral filamentous appendages. Revised keys to fabriciin genera and selected species are provided. Cladistic relationships of these new genera and species to other Fabriciinae are examined and the status of some characters are reviewed. Whereas previous analyses have supported a monophyletic Augeneriella on the basis of branched, vascularized ventral filamentous appendages, present results show Augeneriella paraphyletic relative to Fabricia Blainville, 1828, Novafabricia, Fabricinuda Fitzhugh, 1990 Parafabricia Fitzhugh, 1992 and Brifacia. Similarly, some topologies show Novafabricia, which has only been defined by the presence of poorly developed dorsal lips, to be paraphyletic relative to Fabricia, Fabricinuda, Parafabricia, and Brifacia. The cladistic analyses do, however, support recognition of Brifacia and Pseudoaugeneriella. With the addition of Brifacia, the presence of unbranched, vascularized appendages is plesiomorphic for the Fabriciinae, which has not been previously hypothesized.     

Revision of the tribe Colpopterini Gnezdilov, 2003 (Homoptera, Fulgoroidea: Nogodinidae)

The tribe Colpopterini Gnezdilov, 2003 is revised, upgraded to the subfamily Colpopterinae, stat. n., and transferred from the family Issidae Spinola to Nogodinidae Melichar. The tribe Colpopterini is recorded from the Afrotropical Region for the first time—Bumerangum deckerti gen. et sp. n. is described from Southern Africa. The tribe Colpopterini s. str. comprises 6 genera: Bumerangum gen. n., Caudibeccus Gnezdilov et O’Brien, 2008, Colpoptera Burmeister, 1835, Jamaha Gnezdilov et O’Brien, 2008, Neocolpoptera Dozier, 1931, and Ugoa Fennah, 1945. The genera Cheiloceps Uhler, 1895, Tempsa Stål, 1866, Eupilis Walker, 1857, and Gabaloeca Walker, 1870 are transferred to the tribe Issini Spinola of the family Issidae. Issus longulus Lethierry, 1890 is transferred to the genus Colpoptera Burmeister. A key to the genera and a list of the species of the tribe Colpopterini are given. Morphological data confirming independent evolution of similar ovipositor types in the families Issidae and Nogodinidae are provided. The term “styletization” is suggested for describing the transformation of the ovipositor from a rounded to an elongate type.     

Phylogeny,classification and evolution of the water scavenger beetle tribe Hydrobiusini inferred from morphology and molecules (Coleoptera: Hydrophilidae: Hydrophilinae)

The water scavenger beetle tribe Hydrobiusini contains 47 species in eight genera distributed worldwide. Most species of the tribe are aquatic, although several species are known to occur in waterfalls or tree mosses. Some members of the tribe are known to communicate via underwater stridulation. While recent morphological and molecular‐based phylogenies have affirmed the monophyly of the tribe as currently circumscribed, doubts remain about the monophyly of included genera. Here we use morphological and molecular data to infer a species‐level phylogeny of the Hydrobiusini. The monophyly of the tribe is decisively supported, as is the monophyly of most genera. The genus Hydrobius was found to be polyphyletic, and as a result the genus Limnohydrobius stat. rev. is removed from synonymy with Hydrobius, yielding three new combinations: L. melaenus comb.n. , L. orientalis comb.n. , and L. tumbius comb.n. Recent changes to the species‐level taxonomy of Hydrobius are reviewed. The morphology of the stridulatory apparatus has undergone a single remarkable transformation within the lineage, from a simple, unmodified pars stridens to one that is highly organized and complex. We present an updated key to genera, revised generic diagnoses and a list of the known distributions for all species within the tribe.     

A new genus of mantidflies discovered in the Oriental region,with a higher‐level phylogeny of Mantispidae (Neuroptera) using DNA sequences and morphology

A remarkable new genus and two new species of Mantispidae (Neuroptera) are described from the Oriental region. Allomantispa Liu, Wu, Winterton & Ohl gen.n. , currently including A. tibetana Liu, Wu & Winterton sp.n. and A. mirimaculata Liu & Ohl sp.n. The new genus is placed in the subfamily Drepanicinae based on a series of morphological characteristics and on the results of total evidence phylogenetic analyses. Bayesian and Parsimony analyses were undertaken using three gene loci (CAD, 16S rDNA and COI) combined with 74 morphological characters from living and fossil exemplars of Mantispidae (17 genera), Rhachiberothidae (two genera) and Berothidae (five genera), with outgroup taxa from Dilaridae and Osmylidae. The resultant phylogeny presented here recovered a monophyletic Mantispidae with ?Mesomantispinae sister to the rest of the family. Relationships among Mantispidae, Rhachiberothidae and Berothidae support Rhachiberothidae as a separate family sister to Mantispidae. Within Mantispidae, Drepanicinae are a monophyletic clade sister to Calomantispinae and Mantispinae. In a combined analysis, Allomantispa gen.n. was recovered in a clade comprising Ditaxis McLachlan from Australia, and two fossil genera from the Palaearctic, ?Promantispa Panfilov (Kazakhstan; late Jurassic) and ?Liassochrysa Ansorge & Schlüter (Germany; Jurassic), suggesting a highly disjunct and relictual distribution for the family.

The tribe Bryocorini (Insecta: Heteroptera: Miridae: Bryocorinae): phylogeny,description of a new genus,and adaptive radiation on ferns

A cladistic analysis of the tribe Bryocorini based on 68 morphological characters is conducted. Bryocorini are supported as a monophyletic group with Eccritotarsini as their sister taxon. Based on the phylogenetic analysis, we redefine the tribe Bryocorini to contain the following seven genera: Bryocorella Carvalho, 1956, Bryocoris Fallén, 1829, Bryophilocapsus Yasunaga, 2000, Cobalorrhynchus Reuter, 1906 gen. dist., D iplazicoris gen. nov. , Hekista Kirkaldy, 1902, and Monalocoris Dahlbom, 1851. The genus Bryocorella is transferred to Bryocorini from the tribe Eccritotarsini. The subgenus Cobalorrhynchus is treated as a separate genus. Diplazicoris is described as monotypic to accommodate D iplazicoris lombokianus sp. nov. An updated diagnosis of the tribe, a key to genera, and a diagnosis of each recognized genus are presented. Selected photomicrographs, scanning micrographs, and illustrations of the pretarsus, metepisternal scent efferent system, metafemoral trichobothria, and morphology of head, pronotum, and male and female genitalia are provided. Mapping of the host data on the revealed tree shows that Bryocorini represent one of the very few currently known examples of the adaptive radiation of a fairly large insect group on ferns. © 2015 The Linnean Society of London     

Generic revision of Cypricercinae McKenzie, 1971 (Crustacea,Ostracoda), with the description of three new genera and one new species and a phylogenetic analysis of the subfamily

The Cypricercinae are one of the most speciose subfamilies of non-marine ostracods, with more than 170 described species, mostly from the tropics. Although the identity of the subfamily as such is clear, because of the presence of unifying characters such as the Triebel’s loop in the attachment of the caudal ramus, the supra-specific taxonomy of this group has long been confused because of lack of good generic and tribal characters. Here, the generic characters of the Cypricercinae are revised. Eleven genera are retained in this subfamily, including three new genera: Bradleytriebella n. gen., Nealecypris n. gen. and Pseudostrandesia n. gen. Tanycypris siamensis n. sp. is described from Thailand. In addition, five species [Bradleystrandesia fuscata (Jurine, 1820), Bradleytriebella tuberculata (Hartmann, 1964), Nealecypris obtusa (Klie, 1933), Pseudostrandesia striatoreticulata (Klie, 1932), Spirocypris horrida (Sars, 1926)] are redescribed. A key to the genera is given. We propose three tribes: the nominal tribe Cypricercini McKenzie, 1971, as well as two new tribes, Bradleystrandesiini n. trib. and Nealecypridini n. trib. To evaluate the systematic relationships within this subfamily, phylogenetic analyses, based on morphological characters of valves and soft parts, were conducted. The Neighbour Joining (NJ) tree strongly supports the classification into three independent tribes, whereas the Maximum Parsimony (MP) tree shows that Bradleystrandesiini n. trib is actually a subgroup of the Cypricercini.

Re‐evolution of a morphological precursor of crypsis investment in the newly revised horned praying mantises (Insecta,Mantodea, Vatinae)

The Neotropical praying mantis tribe Vatini Stål is revised using total evidence phylogenetic analysis based on molecular and coded morphological data. The subfamily Vatinae is redefined to only include Neotropical taxa with the removal of distantly related African and Asian lineages. A new tribe is erected under Vatinae (Heterovatini trib.n. ) for two unique genera with historically unstable taxonomic placement (Heterovates Saussure and Chopardiella Giglio‐Tos). Phylogenetic results and morphology support the synonymy of three genera (Lobovates Deeleman‐Reinhold, Phyllovates Kirby, and Hagiotata Saussure & Zehntner) and the validity of Chopardiella Giglio‐Tos, Heterovates Saussure, Callivates Roy, Pseudovates Saussure, Vates Burmeister, and Zoolea Audinet Serville. A new genus (Alangularis gen.n. ) is created for a former species of Vates with unique morphology and separate phylogenetic placement. All genera are redescribed based on external morphology and the male genital complex. A key to genera for Vatinae is provided with dorsal habitus images of representatives for each genus. A distinct pattern of correlated evolution of morphological characters linked to crypsis was uncovered. Cuticular leg lobes within single leg segments are evolving as sets, and serially homologous lobes appear simultaneously or in close succession. The posteroventral lobes in the apical position on thoracic femora appear to be the precursors to multiple positive rate shifts in the evolutionary accumulation of cryptic features. One shift occurred early in the evolution of Vatinae while the second occurred much later, after the loss and re‐evolution of the posteroventral lobes in the apical position on thoracic femora, a violation of Dollo's law.

Two new taxa of subtribe Rhaconotina (Hymenoptera: Braconidae,Doryctinae, Doryctini) from Africa,with a key to subtribe genera

A new genus, Grangerdoryctes gen. n. (with type species Aivalykus niger Granger), from Madagascar and a new subgenus Pararhacon subgen. n. of the genus Rhaconotus Ruthe (type species R. (P.) haeselbarthi sp. n.) from South Africa are described and illustrated. A discussion of genera without a second radiomedial vein of the fore wing in the tribe Doryctini is presented. The position and content of the subtribe Rhaconotina are discussed and a key for determination of the genera of this subtribe is proposed.     

Evolution of wing polymorphism and genital asymmetry in the thread‐legged bugs of the tribe Metapterini Stål (Hemiptera,Reduviidae, Emesinae) based on morphological characters

Wing polymorphism and asymmetric male genitalia are intriguing morphological phenomena occurring in insects. Among Emesinae, or thread‐legged bugs, the tribe Metapterini Stål exhibits these two interesting morphological attributes. Nonetheless, evolutionary interpretations of these phenomena cannot be put forward because phylogenetic hypotheses for Emesinae are lacking. Thread‐legged bugs are easily recognized among assassin bugs due to their elongated and seemingly delicate body. The tribe Metapterini has 28 genera and approximately 280 described species. The only available phylogenetic hypothesis among Emesinae tribes was proposed by Wygodzinsky (1966), and it hypothesized Deliastini Villiers as the sister group of Metapterini, although this hypothesis has never been tested with cladistic approaches. Recent analyses using character sets of genitalia and prolegs suggest that Metapterini might not be monophyletic. In order to test these ideas, we compiled a morphological dataset of 138 characters that includes external morphological characters, detailed features of prolegs and genitalia of both sexes for Metapterini, which were analysed cladistically including 55 terminals, comprising 24 genera (85.7% of the generic diversity), 43 species of Metapterini and 12 outgroups. Metapterini was recovered as paraphyletic by the inclusion of Bergemesa Wygodzinsky, Palacus Dohrn and Stalemesa Wygodzinsky, all currently assigned to Deliastini. Gardena Dohrn (Emesini) was recovered as the sister group of Metapterini + Deliastini as suggested by Wygodzinsky (1966). Based on these results, we synonymize Deliastini syn. n. with Metapterini sensu n. and propose two new genera: Bacata Castro‐Huertas & Forero gen. n. , for three Andean species previously placed in Liaghinella Wygodzinsky, and Valkyriella Castro‐Huertas & Forero gen. n. for Ghilianella borgmeieri Wygodzinsky. Ancestral state reconstruction of wing polymorphism indicates that males and females were fully winged in the ancestor of Metapterini sensu n. with two independent evolutionary transitions to the apterous and brachypterous conditions. The analysis of the symmetry of the male genitalia shows an ancestor with symmetric male genitalia and two independent emergences of asymmetrical male genitalia in Metapterini.     

Giselinidae fam. nov., a new monophyletic group of cyclopoid copepods (Copepoda, Crustacea) from the Atlantic deep sea

Four new species of Cyclopoida from deep-sea waters are described and placed in two new genera: Giselina gen. n. and Sensogiselina gen. n. The new genera and species belong to a new monophyletic group within the cyclopinid cyclopoids. A new name, Giselinidae, is proposed for this monophylum. The new family is characterised by the combination of the following characters: (1) tergite of leg 1 fused to cephalosome dorsally, but incompletely fused laterally, (2) absence of aesthetascs on ancestral antennulary segments XVI, XXI and XXV, (3) absence of antennary exopodal setae, (4) presence of only three spines on distal exopodal segment of leg 1, (5) absence of inner setae on first endopodal segments of legs 1–4, (6) outer terminal and distal inner elements of distal endopodal segment of leg 4 transformed into spines, (7) distal outer element of leg 5 exopod transformed into a spine, (8) leg 6 with only one seta, and (9) furcal setae I and III located on dorsal margin.

Tricalcaria Han gen. nov., a remarkable new genus with three hind‐tibial spurs belonging to the tribe Trichopterygini,with description of a new species from China (Lepidoptera: Geometridae: Larentiinae)

Tricalcaria Han gen. nov. and its type species Tricalcaria stueningi Han sp. nov. are described from China. Morphological characters, including those of the male and female genitalia, are figured. The main diagnostic characters of Tricalcaria are: hind tibia with three spurs in both male and female; ventral margin of costal protrusion bearing a series of long, hook‐like, sclerotized setae in the male genitalia; female papilla analis modified and bearing over part of its surface broad blade‐like sclerotized setae. The wing pattern, venation, and genitalia of this genus are compared with those of the most closely related genera, Tristeirometa Holloway, 1997, Hypocometa Warren, 1896, and Phthonoloba Warren, 1893. Tribal placement is discussed, with the conclusion that the new genus should be placed in the tribe Trichopterygini.     

Hecabolomorpha n. gen., a new Asian genus from the tribe Hecabolini (Hymenoptera: Braconidae: Doryctinae)

A new Oriental genus Hecabolomorpha n. gen. with the type species H. asiatica n. sp. is described and illustrated from India and Central China. The position of this genus in the tribe Hecabolini and its relations with hecaboline genera are discussed.     

Phylogeny and evolution of phytophagous ladybird beetles (Coleoptera: Coccinellidae: Epilachnini), with recognition of new genera

Phytophagous ladybird beetles of the tribe Epilachnini are a cosmopolitan, species‐rich group of significant economic importance as pests of agricultural crops. The tribe is well characterized morphologically and clearly monophyletic, but very little is known about its internal phylogenetic relationships and their genus‐level taxonomy. In order to infer the evolutionary history of Epilachnini, test its monophyly and provide a phylogeny‐based classification, we assembled a comprehensive dataset, consisting of four DNA markers (18S and 28S rRNA and 16S, COI mtDNA) and a matrix of 104 morphological characters for 153 species of Epilachnini representing all previously recognised genera, ～11% of the known species, and 14 outgroup taxa. Molecular, morphological and combined datasets were analysed using maximum likelihood, parsimony and Bayesian inference. Bayes factors and Approximately Unbiased tests (AU) were used to compare alternative phylogenetic hypotheses of unconstrained and backbone‐constrained analysis. Only 14 of the 25 included genera were recovered monophyletic, as originally defined. Afidentula Kapur, Afidenta Dieke, Afissula Kapur, Epilachna Chevrolat, Henosepilachna Li Toxotoma Weise and Mada Mulsant are shown to be poly‐ or paraphyletic; Chnootriba Chevrolat, Subafissa Bielawski, Lalokia Szawaryn & Tomaszewska and Papuaepilachna Szawaryn & Tomaszewska form monophyletic groups within larger clades of genus level. All of these genera are redefined here. The two largest genera of Epilachnini, Epilachna Chevrolat and Henosepilachna Li were represented by multiple monophyletic clades, which we described as new genera: Chazeauiana Tomaszewska & Szawaryn gen.n. ; Diekeana Tomaszewska & Szawaryn gen.n .; Fuerschia Tomaszewska & Szawaryn gen.n. and Ryszardia Tomaszewska & Szawaryn gen.n . The following new synonyms are proposed: Afissa Dieke (=Afissula Kapur); Henosepilachna Li in Li & Cook (=Subafissa Bielawski); Papuaepilachna Szawaryn & Tomaszewska (=Lalokia Szawaryn & Tomaszewska).

A new genus and species of Coenosiini from Costa Rica (Diptera,Muscidae, Coenosiinae)

Palpilongus gen. n. is herein described for one species – Palpilongus bifurcus sp. n., from Costa Rica, based on male and females. The striking morphological characters of the species – palpus very long, about as long as prementum; upper calypter truncate and very short and setae of male sternite 5 bifurcated, confirm that this new species is also a new genus in the tribe Coenosiini. Male and female terminalia were dissected and illustrated.     

A new genus and a new species of tachinids (Diptera,Tachinidae) from the south of middle Asia

Ventoplagia gen. n. is described, with the type species Ventoplagia brevirostris sp. n. The frontal bristles extending only to the base of the pedicel, 2+3 dorsocentral bristles, 0+2 intraalar bristles, the absence of prealar bristle, the short and fine anepimeral (pteropleural) bristle, the scutellum without lateral bristles, and the welldeveloped posteroventral bristle of the hind tibia indicate that the new genus belongs to tribe Minthoini. Ventoplagia gen. n. is closely related to the genus Palmonia Kugler. The characters distinguishing these genera are given.     

Parobia husbandi gen. n., sp. n. (Acari: Podapolipidae): subelytral parasites of paropsine beetles (Coleoptera: Chrysomelidae)

Abstract Parobia husbandi gen. n., sp. n. is described from material collected from the subelytra of the southern eucalyptus leaf beetle, Chrysophtharta agricola (Chapuis), in Tasmania, Australia. Parobia gen. n. is distinguished from other podapolipid genera adult males and females with four pairs of legs and no setae on genua I−IV and femora III−IV, adult females with setae v1 and sc2 < 20 µm, and at least two pairs of coxal setae peg-like, adult males with dorso-terminal genitalia, dorsal shields C-D-E fused, and physogastric larval females with plates C and D entire. A series of morphological plesiomorphies and biological apomorphies link Parobia gen. n. with Chrysomelobia Regenfuss, the most basal genus of Podapolipidae.     

Systematic revision,molecular phylogeny and biogeography of the antlion tribe Acanthoplectrini (Neuroptera: Myrmeleontidae: Dendroleontinae), with emphasis on the Oriental lineage

The tribe Acanthoplectrini (Myrmeleontidae: Dendroleontinae) includes a group of antlion genera widely distributed across the Australasian and Oriental regions. The intergeneric and interspecific relationships between or within the Australian and Oriental lineages of this tribe as well as their historical biogeography remain largely unexplored. Here, we present a molecular phylogenetic and biogeographic analyses of Acanthoplectrini to infer the diversification history of this tribe, with emphasis on the Oriental lineage. Both the Oriental and Australian lineages are monophyletic and recovered as sister groups. Ancestral area reconstruction suggests that the ancestor of Acanthoplectrini might have been once widely distributed from Indochina to Australia and then split into the Oriental and Australian lineages during the early-Miocene. Our analyses recovered northeastern Indochina and south China as the ancestral range of the Oriental Acanthoplectrini. During the mid-Miocene to the mid-Pliocene, orographic events such as the rising of mountain ranges (including the Himalayas) and the formation of major islands in southeastern Asia triggered several dispersal and vicariance events in the Oriental Acanthoplectrini, driving their speciation. We revise the classification of the Oriental Acanthoplectrini, establishing the new genus Paralayahima gen. n. , which is recovered sister to Layahima Navás. Moreover, we describe four new species of Layahima, Layahima aspoeckorum sp. n. , Layahima monba sp. n. , Layahima lhoba sp. n. and Layahima xinliae sp. n. , and we reinstate two previously synonymized species, Layahima melanocoris (Yang) stat. rev. and comb. n. and Layahima nebulosa Navás stat. rev.
