Taxonomic revision of the land snail genera Macrochlamys Gray, 1847 and Sarika Godwin-Austen, 1907 (Eupulmonata: Ariophantidae) from south-eastern Myanmar,with descriptions of three new species

ABSTRACT

Knowledge of Myanmar land snails is based on the late eighteenth to early twentieth century literature and many species need to be re-investigated, especially in the genera Macrochlamys Gray, 1847 and Sarika Godwin-Austen, 1907. In order to update this knowledge, this paper presents information on these two related genera based on new materials from south-eastern Myanmar. Fifteen species are recognised in the south-east of Myanmar. Of these, live material was available for eight Macrochlamys and Sarika species and these are described in full herein, based on data from the shell, external morphology and genitalia, including three species new to science (M. brachystia n. sp., S. concavata n. sp. and S. lopa n. sp.) and five species redescribed (M. aspides, M. kelantanensis, M. petasus, S. consepta and S. obesior). The remaining five species are known only from their shell morphology (M. cauisa, M. perpaula, M. poongee, M. salwinensis and S. birmana) and two species are known from genitalia (S. dugasti and S. resplendens). For these species the shells are figured and some taxonomic remarks are provided.

Review of the millipede family Trichopolydesmidae in the Oriental realm (Diplopoda,Polydesmida), with descriptions of new genera and species

In the Oriental Region, the large, basically Northern Hemisphere family Trichopolydesmidae is shown to currently comprise 18 genera and 43 species. Based mainly on gonopod structure, all of them, as well as the whole family, are (re)diagnosed, including five new genera and seven new species. These new taxa are keyed, also being the first to be described from Indochina in general and from Vietnam in particular: Aporodesmella gen. n., with three species: A. securiformis sp. n. (the type species), A. similis sp. n. and A. tergalis sp. n., as well as the following four monotypic genera: Deharvengius gen. n., with D. bedosae sp. n., Gonatodesmus gen. n., with G. communicans sp. n., Helicodesmus gen. n., with H. anichkini sp. n., and Monstrodesmus gen. n., with M. flagellifer sp. n. In addition, Cocacolaria hauseri Hoffman, 1987, hitherto known only from New Ireland Island, Papua New Guinea, is redescribed based on material from Vanuatu whence it is recorded for the first time. One of the new genera, Gonatodesmus gen. n., provides a kind of transition or evolutionary bridge between Trichopolydesmidae and Opisotretidae, thus reinforcing the assignment of these two families to the single superfamily Trichopolydesmoidea.     

Small but not ephemeral: newly discovered species of Aphelinidae and Trichogrammatidae (Insecta: Hymenoptera: Chalcidoidea) from Eocene amber

New species of fossil Aphelinidae and Trichogrammatidae are described from middle Eocene (Lutetian) Baltic amber (41.3–47.8 Ma). A new subfamily, two new genera and three new species of Aphelinidae are described, with comments on their placement: Phtuaria fimbriae gen.n. , sp.n. in Phtuariinae subf.n. , Glaesaphytis interregni gen.n. , sp.n. and Centrodora brevispinae sp.n. These represent the first described true fossil Aphelinidae. Four new species of Trichogrammatidae are described: Mirufens illusionis sp.n. , Palaeogramma eos gen.n. , sp.n. , Pterandrophysalis plasmans sp.n. and Szelenyia terebrae sp.n. , thus expanding our knowledge of fossil Trichogrammatidae beyond the single previously described species. The presence of recognizable extant genera of Aphelinidae and Trichogrammatidae in the Eocene suggests that the morphology of these genera has been relatively invariant despite highly variable conditions during and since the Eocene.

Phylogeny of Evanioidea (Hymenoptera,Apocrita), with descriptions of new Mesozoic species from China and Myanmar

The phylogeny of the superfamily Evanioidea is presented using morphology and DNA sequence data of selected extant and fossil genera by employing two phylogenetic methods, maximum parsimony and Bayesian inference. Based on our new results, the monophyly of Evanioidea is corroborated. Evanioidea, Anomopterellidae, Othniodellithidae, Andreneliidae and Evaniidae are monophyletic families, while Praeaulacidae, Aulacidae, Baissidae and Gasteruptiidae are paraphyletic families. In addition, four new genera (Sinuevania gen.n. , Curtevania gen.n. , Exilaulacus gen.n. , Heterobaissa gen.n. ) with five new species (Sinuevania mira sp.n. , Curtevania enervia sp.n. , Exilaulacus loculatus sp.n. , Exilaulacus latus sp.n. , Heterobaissa apetiola sp.n. ), and five additionally new species (Newjersevania longa sp.n. , Newjersevania brevis sp.n. , Cretevania tenuis sp.n. , Cretevania venae sp.n. , Praeaulacus rectus sp.n. ) and one new combination [Cretevania mitis (Li, Shih & Ren, 2014a) comb.n. ] are described based on well‐preserved fossils from the Middle Jurassic Jiulongshan Formation in Inner Mongolia, China, the Early Cretaceous Yixian Formation in Liaoning, and mid‐Cretaceous amber from Myanmar. This study documents the diversification of one major lineage of the mid‐Mesozoic parasitoid revolution that dramatically changed food‐web relationships in terrestrial ecosystems.

Revision of the Cales noacki species complex (Hymenoptera,Chalcidoidea, Aphelinidae)

The genus Cales (Hymenoptera: Aphelinidae) includes 13 species worldwide, of which 10 form a highly morphologically uniform species complex with a native range in the Neotropical region. We recognize ten species previously attributed to a single Neotropical species, Cales noacki Howard, which in the strict sense is a species broadly disseminated to control woolly whitefly. A neotype is designated for C. noacki, and it is redescribed based on specimens molecularly determined to be conspecific with the neotype. Newly described species include: C. bicolor Mottern, n.sp ., C. breviclava Mottern, n.sp ., C. brevisensillum Mottern n.sp ., C. curvigladius Mottern, n.sp ., C. longiseta Mottern, n.sp ., C. multisensillum Mottern n.sp ., C. noyesi Mottern, n.sp ., C. parvigladius Mottern, n.sp . and C. rosei Mottern, n.sp . Species are delimited based on a combination of morphological and molecular data (28S‐D2 rDNA and COI). Additional specimens are included in the phylogenetic analyses and although these likely represent several new species, we lack sufficient specimen sampling to describe them at this time. Cales are highly morphologically conserved and character‐poor, resulting in several cryptic species. A molecular phylogeny of the known Neotropical species based on 28S‐D2–5 rDNA and a 390‐bp segment of COI is included, and identification keys to males and females are provided. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:7FEB0479‐9B2E‐48E8‐8603‐4B7C2759D4EC .     

Gondwanan Gymnochilini (Coleoptera: Trogossitidae): generic concepts,review of New Zealand species and long‐range Pacific dispersal

Members of Leperina Erichson (Trogossitidae: Gymnochilini) from New Zealand, New Caledonia and Lord Howe Island are morphologically similar to members of the endemic Juan Fernandez Island genus Phanodesta Reitter, sharing at least one obvious character, elytral carinae that are beaded and contain well‐defined punctures. To test the monophyly of Leperina and Phanodesta, we reconstructed phylogenetic relationships of the genera of the tribe Gymnochilini by a cladistic analysis of 22 terminals and 47 adult characters rooted with one genus of trogossitine. Leperina is rendered paraphyletic by the placements of Seidlitzella Jakobson and Phanodesta. Kolibacia n.gen. (type species Leperina tibialis Reitter) is described for east Palaearctic species included formerly in Leperina (two new combinations); New Zealand Leperina and other species from New Caledonia and Lord Howe Island (Ostoma pudicum Olliff) are transferred to Phanodesta (six new combinations); and the remaining species are retained in Leperina. The following species are described as new: Phanodesta carinata n.sp., P. manawatawhi n.sp., P. oculata n.sp. and P. tepaki n.sp. Leperina ambiguum Broun is transferred to Grynoma Sharp resulting in a new combination and three new synonymies for New Zealand trogossitines: Leperina interrupta Brookes n.syn. and Leperina sobrina (White) n.syn. [= Phanodesta farinosa (Sharp)], and Trogosita affinis White n.syn. (= Tenebroides mauritanicus Linnaeus). A key to the New Zealand species and a checklist for the species of the Kolibacia, Leperina and Phanodesta are provided. The derived placement of Juan Fernandez Phanodesta in the phylogeny is evidence for long‐distance dispersal from Australasia. A tally of all Juan Fernandez Islands Coleoptera shows derivation mostly from Chile and South America, with few from the southern Pacific region, rarely from Australasia.     

New fossils from China elucidating the phylogeny of Praesiricidae (Insecta: Hymenoptera)

A new subfamily of Praesiricidae (Pamphilioidea), Decorisiricinae subfam.n. , is erected based on three new genera: Decorisiricius gen.n. , Limbisiricius gen.n. and Brevisiricius gen.n. Two new species – Decorisiricius patulus gen. et sp.n. and D. longus sp.n. – from the Lower Cretaceous Yixian Formation and three species –Limbisiricius aequalis gen. et sp.n. , Limbisiricius complanatus sp.n. and Brevisiricius partialis gen. et sp.n. – from the Middle Jurassic Jiulongshan Formation, are described. Based on these well‐preserved new fossil specimens and previously published data, the nonmonophyly of Praesiricidae is confirmed and the phylogenetic relationships of species of Praesiricidae are analysed for the first time. Two main clades within Praesiricidae are recognized from the cladistic analysis: Decorisiricinae subfam.n. forms a monophyletic lineage, with the remaining members of Praesiricidae plus Megalodontes (Megalodontesidae) forming its sister group. The two subfamilies Archoxyelydinae and Praesiricinae are discarded with no strong supported synapomorphic characters based on phylogenetic research. A key to all genera of Praesiricidae is provided.

The high‐Andean Jivarus Giglio‐Tos (Orthoptera,Acridoidea, Melanoplinae): systematics,phylogenetic and biogeographic considerations

The high‐Andean genus Jivarus Giglio‐Tos from Ecuador, Colombia and Peru is revised. Morphological cladistic analysis indicated that Jivarus montanus and the new species digiticercus sp.n. and rugosus sp.n. must be treated as a separate genus, Maylasacris gen.n. The remaining species included in the analysis are assigned to the genus Jivarus, for which the following six species groups are identified: americanus group, antisanae group, carbonelli group, cohni group, pictifrons group and jagoi group. Twenty‐nine species are recognized for Jivarus, with ten described as new: J. rectus sp.n. , J. megacercus sp.n. , J. spatulus sp . n. , J. auriculus sp.n. , J. riveti sp.n. , J. sphaericus sp.n. , J. discoloris sp . n. , J. profundus sp.n. , J. ronderosi sp.n. and J. guarandaensis sp.n. The following new synonymies are proposed: Jivarus albolineatus Ronderos with J. antisanae (Bolivar) syn.n. , J. cerdai Ronderos and J. osunai Ronderos with J. alienus (Walker) syn.n. , and J. rubriventris Ronderos with J. ecuadorica (Hebard) syn.n. ; the new combinations Jivarus ecuadorica (Ronderos) comb.n. and Maylasacris montanus (Ronderos) comb.n. are proposed. Keys to the species of the genera and a review of the morphological characters defining the taxa are provided. Patterns of distribution of the clades coincide with the geography of the northern Andes of Colombia and Ecuador. Areas of endemism of the Jivarus species groups and Maylasacris are delimited by both the high‐altitude curves, including transverse zones, and the drier climates of the intra‐Andean valleys, clearly indicating recent, post‐glacial palaeogeography, as shown also in vegetation distributions. This paper has been formatted with many embedded links to images of type and paratype specimens, maps based on geo‐referenced specimen data and species keys available on the Orthoptera Species file online ( http://orthoptera.speciesfile.org ).     

Three new species of oxyuroid nematodes,including two new genera,from freshwater catfishes in Brazil

Three new oxyuroid nematode species of the family Pharyngodonidae are described from the intestine of freshwater catfishes in Brazil (River Paraná), two of them being representatives of new monotypic genera: Ichthyouris brasiliensis n. sp. from Pterygoplichthys aculeatus, Brasilnema pimelodellae n. g., n. sp. from Pimelodella gracilis, and Parasynodontisia petterae n. g., n. sp. from Rhinelepis aspera. I. brasiliensis n. sp. differs from the only other congeneric species, I. ro, mainly in the absence of a pair of plate-like structures in the male caudal region, shorter caudal alae, the presence of a pair of conspicuous lateral spines at the level of the anal opening in the female and by other features. Brasilnema n. g. is characterised mainly by a hexagonal oral opening, a broad buccal capsule containing three teeth, a simple spicule and an amphidelphic uterus, whereas Parasynodontisia n. g. is characterised by a triangular oral opening and an amphidelphic uterus in the female; both genera possess six small, triangular, circumoral lamellae slightly raised above the apical surface. The paper includes a key to the pharyngodonid genera whose species are parasitic in fishes.     

Three new species of fleas belonging to the genus Macrostylophora from the three‐striped ground squirrel,Lariscus insignis,in Java

Three new species of fleas belonging to the genus Macrostylophora (Siphonaptera, Ceratophyllidae) are described from the three‐striped ground squirrel, Lariscus insignis, from Tjibodas, West Java (Jawa Barat), Indonesia at an elevation of 1500 m. Macrostylophora larisci sp. n. is described from three male specimens, Macrostylophora debilitata sp. n. is described from one male and Macrostylophora wilsoni sp. n. is described from one female. Non‐genital morphological characters of the female specimen, including ctenidial spine shapes and lengths, show that it is not the corresponding female for either M. larisci sp. n. or M. debilitata sp. n. It is unusual for three different species of congeneric fleas to parasitize the same host species in the same geographical location. These three new species represent the first known records of Macrostylophora from Java and they could be enzootic vectors between rodents of flea‐borne zoonotic pathogens such as Rickettsia typhi and Yersinia pestis, both of which are established on Java. A list is provided of the 43 known species and 12 subspecies of Macrostylophora together with their known geographical distributions and hosts. A map depicting the distributions of known Indonesian (and Bornean) species of Macrostylophora is also included.     

Phylogeny of ensign scale insects (Hemiptera: Coccoidea: Ortheziidae) based on the morphology of Recent and fossil females

The Ortheziidae (ensign scale insects) is a morphologically well‐defined family. The morphology and occurrence in the fossil record suggests a probable early origin of the family in scale insect evolution. The present phylogenetic analysis – based on 69 morphological characters of female ortheziids, using 39 exemplar Recent species – provides the first analytical assessment of relationships among living genera of the family, as well as the relationships of eight fossil species, based on complete, well‐preserved specimens in amber. Monophyly of the subfamilies Newsteadiinae, Ortheziinae and Ortheziolinae is supported, but Nipponortheziinae is found to be paraphyletic by inclusion of the Ortheziolinae. Thus, the subfamily Ortheziolinae is reduced in rank to tribe Ortheziolini stat.n. , which now includes Matileortheziola Kozár & Foldi, Ortheziolacoccus Kozár, Ortheziolamameti Kozár and Ortheziola?ulc. Consequently, the tribes Matileortheziolini, Ortheziolacoccini and Ortheziolamametini are synonymized ( syn.n. ) here under Ortheziolini. Five new species and one new genus of fossil ensign scales are described from three amber deposits: Burmorthezia gen.n. with type species Burmorthezia kotejai sp.n. and also B. insolita sp.n ., both in mid‐Cretaceous Burmese amber (98 Ma) and Arctorthezia baltica sp.n. in Eocene Baltic amber (c. 43 Ma) based on second‐instar nymphs; Mixorthezia kozari sp.n . and M. dominicana sp.n . in Miocene Dominican amber (c. 17 Ma) based on adult females. Fossil placements are unambiguous, with Burmorthezia forming a stem to crown‐group (Recent and Tertiary) Ortheziidae. A summary of described fossil ortheziids is provided.     

Report on the Polycystididae (Rhabdocoela, Kalyptorhynchia) from Australia, with the Description of Twelve New Species and Six New Genera

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.     

Myrtlemiris,a new genus and new species of Australian plant bugs (Insecta: Heteroptera: Miridae): systematics,phylogeny and host associations

A new Australian genus of Orthotylinae, Myrtlemiris Cheng, Mututantri & Cassis gen.n. , is described, with nine included species described as new to science (M. agnew sp.n. , M. astartephila sp.n. , M. meanarra sp.n. , M. newmanensis sp.n. , M. rubrocuneatus sp.n. , M. russulatus sp.n. , M. silveirae sp.n. , M. tesselatus sp.n. , M. yalgoo sp.n. ). A phylogenetic analysis based on 39 morphological characters is presented for all Myrtlemiris species and 6 outgroup taxa. This analysis establishes Myrtlemiris as monophyletic, defined by a broad apophysis on the left paramere. A key to species is provided and diagnostic characters are illustrated. Myrtlemiris is endemic to southwest Western Australia. Host plants for Myrtlemiris species are near restricted to the myrtaceous tribe Chamelaucieae.

New and little known crickets of the subfamily Phalangopsinae (Orthoptera,Gryllidae): 6. Neotropical taxa of the tribes Phalangopsini and Paragryllini

Two new genera, ten new species, and two new subspecies: Uvaroviella izerskyi sp. n., U. morona sp. n., U. ucayali sp. n., U. pastaza sp. n., U. affinis sp. n., U. bolivia sp. n., U. bora atalaya subsp. n., Kevanacla orientalis contraria subsp. n., Peruacla solitaria gen. et sp. n., Ecuadoracla propria gen. et sp. n., Adelosgryllus spurius sp. n., and A. phaeocephalus sp. n. are described. The tribe Paragryllini is divided into three subtribes: Paragryllina Desutter, 1988 stat. n., Neoaclina Desutter, 1988 stat. n., and Strogulomorphina Desutter 1988, stat. n. The composition of the genera Uvaroviella Chop. and Neoacla Desutter is discussed. The species from Costa Rica and the Antilles are supposed to belong to these genera and subgenera. New synonymy [U. trinidadi Gorochov, 2007 = U. enodos Otte et Perez-Gelabert, 2009, syn. n. and N. multivenosa (Chopard, 1937) = Selvacla choreutes Otte, 2006, syn. n.] is proposed.     

A taxonomic study of Chinese species of the insidiosus group of Metaphycus (Hymenoptera,Encyrtidae)

In this paper, twelve insidiosus-group species of the genus Metaphycus Mercet from China are reviewed. Five species, M. corniae sp. n., M. cylindricus sp. n., M. deltoideus sp. n., M. transversus sp. n. and M. yaanensis sp. n., are described as new to science. A key to the females of these species is given to facilitate species recognition. Photomicrographs are provided to illustrate morphological characters of these species. All specimens, unless otherwise specified, are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing.     

New fossil Ochteridae (Hemiptera: Heteroptera: Ochteroidea) from the Upper Mesozoic of north‐eastern China,with phylogeny of the family

Specimens of the velvety shore bugs (Hemiptera: Ochtheridae) occur in the Early Cretaceous Yixian Formation in north‐eastern China. We describe two new genera and three new species –Pristinochterus ovatus Yao, Zhang & Ren sp. nov., Floricaudus multilocellus Yao, Ren & Shih gen.n. et sp.n. and Angulochterus quatrimaculatus Yao, Zhang & Ren gen.n. et sp.n. – from this deposit. A cladistic analysis based on a combination of fossil and extant taxa, and their morphological characters, clarifies the phylogenetic status of the new fossils and allows the reconstruction of relationships within the family Ochteridae. Two main clades within Ochteridae are recognized from the cladistic analysis: Pristinochterus Yao Cai & Ren and Floricaudus Yao, Ren & Shih gen.n. form a monophyletic lineage; and Angulochterus Yao, Zhang & Ren gen.n. emerges as a sister group to all extant velvety shore bugs. A key to all fossil and extant genera of Ochteridae is provided.
