A key to the genera and species of the transversely-dividing Flabellidae (Anthozoa,Scleractinia, Flabellidae), with a guide to the literature,and the description of two new species

The transversely-dividing flabellids consist of five genera (Truncatoflabellum, Placotrochides, Blastotrochus, Placotrochus, and Falcatoflabellum) and 45 species. A dichotomous key is provided for these five genera as well as the species of the genus Truncatoflabellum and Placotrochides, the other three genera being monotypic. A tabular key is also provided for the 38 species of Truncatoflabellum. Two new combinations are suggested (Truncatoflabellum gambierense and Truncatoflabellum sphenodeum) and two new species are described (Truncatoflabellum duncani and Truncatoflabellum mozambiquensis). All but one species are illustrated and accompanied by their known distribution and a guide to the pertinent literature for the species. New records of 19 of the 45 species are listed. The transversely-dividing flabellids range from the Middle Eocene to the Recent at depths of 2–3010 m, and constitute 60% of the 65 known extant species of transversely-dividing Scleractinia.     

A new species group in Megaselia,the lucifrons group,with description of a new species (Diptera,Phoridae)

With 1,400 described species, Megaselia is one of the most species-rich genera in the animal kingdom, and at the same time one of the least studied. An important obstacle to taxonomic progress is the lack of knowledge concerning the phylogenetic structure within the genus. Classification of Megaselia at the level of subgenus is incomplete although Schmitz addressed several groups of species in a series of monographs published from 1956 to 1981. Another problem is the lack of molecular phylogenetic analyses to support morphology-based conclusions. As a contribution towards addressing these problems, we here circumscribe a previously unrecognized monophyletic lineage of Megaselia consisting of species similar to Megaselia lucifrons. We base this taxonomic decision on morphological study of an extensive phorid material from Sweden, complemented by molecular analyses of select exemplars using two markers (COI and 28S). We name the clade the lucifrons species group, and show that it contains three distinct species. Our results also demonstrate that Megaselia subnitida Lundbeck, 1920, previously treated as a synonym of Megaselia lucifrons Schmitz, 1918, is a separate species, and we remove it from synonymy. The third species in the group was previously unknown; we describe it here as Megaselia albalucifrons sp. n.     

Three new genera of Neotropical Mimallonidae (Lepidoptera,Mimallonoidea, Mimallonidae) with descriptions of three new species

Three new genera of Mimallonidae are described. The monotypic genus Tostallo gen. n. is erected to contain “Perophora” albescens Jones, 1912, which was previously placed in the preoccupied genus Perophora Harris, 1841 and was never formally moved to a valid genus. Perophora is a junior homonym of Cicinnus Blanchard, 1852, but the name albescens is not appropriately placed in Cicinnus due to external and genitalia characteristics entirely unique to the species albescens. The female of Tostallo albescens comb. n. is described and both sexes are figured for the first time. Auroriana gen. n. is erected to contain Auroriana florianensis (Herbin, 2012), comb. n. previously described as Cicinnus florianensis, and two new species: Auroriana colombiana sp. n. from Colombia and Auroriana gemma sp. n. from southeastern and southern Brazil. The female of Auroriana florianensis is described and figured for the first time. Finally, the monotypic genus Micrallo gen. n. is erected to include a new species, Micrallo minutus sp. n. described from northeastern Brazil.     

Ectomyelois Heinrich, 1956 in China,with descriptions of two new species and a key (Lepidoptera,Pyralidae, Phycitinae)

Only three species belonging to the genus Ectomyelois Heinrich, 1956 are recorded from China, of which two species, Ectomyelois bipectinalis sp. n. and Ectomyelois furvivena sp. n. are described as new. We discuss the status of Ectomyelois that has been treated as a junior synonym by previous authors; we treat it as a valid genus, revised status, based on characters of the venation and female genitalia. Photographs of the adults and illustrations of the genitalia are given, along with a key to the three known Chinese species.     

Two new species of the genus Diostracus Loew from Tibet,with a key to the Himalayan fauna (Diptera,Dolichopodidae)

Previously only one species of the genus Diostracus was known to occur in Tibet. Here the following two new species are added to the fauna of Tibet: Diostracus acutatus sp. n. and Diostracus tibetensis sp. n. Their relationships with similar species are discussed. A key to the species of Diostracus from the Himalayas is presented.     

New species of the genus Mahinda Krombein, 1983 (Hymenoptera,Chrysididae, Amiseginae)

Three new species of Mahinda are described, bo from Vietnam, borneensis from Malaysian Borneo and sulawesiensis from northern Sulawesi. A key to the three known species is provided including the previously described species, saltator Krombein, 1983.     

Description of Parvocalanus leei sp. n. (Copepoda,Calanoida, Paracalanidae) in Western Korea,with comments on the taxonomic position of Paracalanus arabiensis Kesarkar & Anil, 2010

A new species of paracalanid calanoid copepod Parvocalanus leei sp. n., is described from specimens collected in shallow waters of Western Korea. The new species is closely similar to Parvocalanus arabiensis (Kesarkar & Anil, 2010), Parvocalanus crassirostris (F. Dahl, 1894), Parvocalanus latus Andronov, 1972, and Parvocalanus scotti (Früchtl, 1923) in having two short terminal spines on the distal segment of the fifth leg and a similar rostrum in the female, but can be readily distinguished from its congeners by the body size, relative length of antennules, segmentation of endopod of leg 1, and pattern of ornamentation of spinules on legs 1 to 4 in the female. The taxonomic position of Parvocalanus arabiensis and the validity of the genus Parvocalanus Andronov, 1970 are also discussed.     

On the identity of Chamaedrilus glandulosus (Michaelsen, 1888) (Clitellata,Enchytraeidae), with the description of a new species

The taxonomy of Chamaedrilus glandulosus (Michaelsen, 1888) s. l., most commonly known previously as Cognettia glandulosa, is revised. A recent molecular systematic study has shown that this taxon harbours two cryptic, but genetically well separated lineages, each warranting species status. In this study these two lineages are scrutinized morphologically, on the basis of Michaelsen’s type material as well as newly collected specimens from Central and Northern Europe. Chamaedrilus glandulosus s. s. is redescribed and Chamaedrilus varisetosus sp. n. is recognized as new to science. The two species are morphologically very similar, differing mainly in size, but seem to prefer different habitats, with Chamaedrilus glandulosus being a larger aquatic species, and Chamaedrilus varisetosus being smaller and mainly found in moist to wet soil.     

The genus Trachionus Haliday, 1833 (Hymenoptera,Braconidae, Alysiinae) new for China,with description of four new species

The genus Trachionus Haliday, 1833 (Hymenoptera, Braconidae, Alysiinae, Dacnusini) is reported for the first time from China. The genus is represented by four new species from Shaanxi province (NW China), which are described and illustrated. An identification key to the species in China is presented, a key to the genera of the Trachionus group and notes on the relationships with other Palaearctic species are added.     

A new species of Eutettix (Hemiptera,Cicadellidae, Deltocephalinae) from Wisconsin

Eutettix latoides sp. n., is described from central Wisconsin. It most closely resembles the Californian species Eutettix latus Hepner, and was collected from Quercus ellipsoidalis.     

A new species of nectar-feeding bat,genus Lonchophylla,from the Caatinga of Brazil (Chiroptera,Phyllostomidae)

We describe Lonchophylla inexpectata sp. n. from the Caatinga of Brazil. This new species can be distinguished from all known species of Lonchophylla that occur in Brazil by dental traits, cranial size, and fur colour. Specimens of Lonchophylla inexpectata have been misidentified as Lonchophylla mordax; but Lonchophylla inexpectata is a pale-venter species, similar in external appearance to Lonchophylla dekeyseri. We have found Lonchophylla inexpectata in the Caatinga of North-eastern Brazil; Lonchophylla mordax along the eastern border of the Caatinga and in the Atlantic Forest–Caatinga ecotone in North-eastern Brazil; and Lonchophylla dekeyseri in the Cerrado of Mid-western Brazil, in the Brazilian Cerrado–Caatinga ecotone, and as far west as the Cerrado of Bolivia.     

Male secondary sexual structures and the systematics of the Thereus oppia species group (Lepidoptera,Lycaenidae, Eumaeini)

The Thereus oppia species group includes species with and without a scent pad, which is a histologically and morphologically characterized male secondary sexual structure on the dorsal surface of the forewing. To assess the hypothesis that these structures are lost evolutionarily, but not regained (Dollo’s Law), the taxonomy of this species group is revised. Thereus lomalarga sp. n., and Thereus brocki sp. n., are described. Diagnostic traits, especially male secondary structures, within the Thereus oppia species group are illustrated. Distributional and biological information is summarized for each species. Three species have been reared, and the caterpillars eat Loranthaceae. An inferred phylogeny is consistent with the hypothesis that scent pads in the Thereus oppia species group have been lost evolutionarily twice (in allopatry), and not re-gained.     

A new species of the genus Timalinyssus Mironov, 2001 (Acarina,Psoroptidia) with a key to known species

The article describes a new species of the feather mite family Pteronyssidae (Acarina: Psoroptidia) from the Gray Sibia Heterophasia gracilis (McClelland) (Passeriformes, Leiothrichidae) in India (Meghalaya, Jaintia Hills, Shnongrim village). Males of Timalinyssus wahlangi sp. n. differ from those of all Timalinyssus species by having the horseshoe-shaped epiandrum with a short anterior extension. Females of the new species differ from those of all previously known species of the genus in having the hysteronotal shield with deep lateral incisions between e2 and f2 setae. A key to all species of the genus Timalinyssus is presented.     

The oribatid mite subgenus Galumna (Galumna) (Acari,Oribatida, Galumnidae) in the Philippines

Five species of the subgenus Galumna (Galumna) (Acari, Oribatida, Galumnidae) are registered in the Philippine oribatid mite fauna. A new species, Galumna (Galumna) makilingensis sp. n., is described; it is most similar morphologically to Galumna (Galumna) tokyoensis Aoki, 1966, but differs from the latter by the morphology of porose areas Aa and Ap, rostral setae, and length of interlamellar setae. Three species, Galumna (Galumna) crenata Deb & Raychaudhuri, 1975, Galumna (Galumna) cf. exigua Sellnick, 1925 and Galumna (Galumna) khoii Mahunka, 1989, are recorded in the Philippines for the first time. The species Galumna (Galumna) crenata is redescribed. An identification key to the Philippine species of Galumna (Galumna) is given.     

Comparative sensitivity to methyl eugenol of four putative Bactrocera dorsalis complex sibling species – further evidence that they belong to one and the same species B. dorsalis

Males of certain species belonging to the Bactrocera dorsalis complex are strongly attracted to, and readily feed on methyl eugenol (ME), a plant secondary compound that is found in over 480 plant species worldwide. Amongst those species is one of the world’s most severe fruit pests the Oriental fruit fly, Bactrocera dorsalis s.s., and the former taxonomic species Bactrocera invadens, Bactrocera papayae and Bactrocera philippinensis. The latter species have been recently synonymised with Bactrocera dorsalis based on their very similar morphology, mating compatibility, molecular genetics and identical sex pheromones following consumption of ME. Previous studies have shown that male fruit fly responsiveness to lures is a unique phenomenon that is dose species-specific, besides showing a close correlation to sexual maturity attainment. This led us to use ME sensitivity as a behavioural parameter to test if Bactrocera dorsalis and the three former taxonomic species had similar sensitivity towards odours of ME. Using Probit analysis, we estimated the median dose of ME required to elicit species’ positive response in 50% of each population tested (ED₅₀). ED₅₀ values were compared between Bactrocera dorsalis and the former species. Our results showed no significant differences between Bactrocera dorsalis s.s., and the former Bactrocera invadens, Bactrocera papayae and Bactrocera philippinensis in their response to ME. We consider that the Bactrocera males’ sensitivity to ME may be a useful behavioural parameter for species delimitation and, in addition to other integrative taxonomic tools used, provides further supportive evidence that the four taxa belong to one and the same biological species, Bactrocera dorsalis.     

A new species of the genus Anteon Jurine (Hymenoptera,Dryinidae) from Laos

A new species of Anteon Jurine, 1807 is described from Laos, Houaphanh Province: Anteon holzschuhi sp. n. Morphologically the new species is similar to Anteon semipolitum Olmi, 2008, but it is distinguished by the sculpture of the face partly reticulate rugose and partly with deep punctures similar to areolae; in Anteon semipolitum the face is completely punctate and unsculptured among punctures. In addition, in the new species the distance from the outer edge of a lateral ocellus to the compound eye (OOL) is about 3.3 times as long as the distance between the inner edges of a lateral ocellus and the median ocellus (OL); in Anteon semipolitum OOL is less than twice as long as OL. Published identification keys to the Oriental species of Anteon are modified to include the new species.     

Lamprops donghaensis sp. n. (Crustacea,Cumacea, Lampropidae), a new species from Korean waters

A new species of Cumacea belonging to the genus Lamprops Sars was collected from the East Sea of Korea. This new species resembles Lamprops comatus Zimmer, Lamprops carinatus Hart, Lamprops flavus Harada, Lamprops pumilio Zimmer, Lamprops tomalesi Gladfelter, and Lamprops obfuscatus (Gladfelter) in lacking lateral oblique ridges on the carapace and lateral setae on the telson. The new species, however, is distinguished from its congeners by having a dorsal concave groove and a lateral rounded depressed area on pereonite 2. The new species is fully illustrated and compared with related species. A key to the world Lamprops species lacking lateral ridges on the carapace is also provided.     

A new genus of soft coral (Cnidaria,Octocorallia) from the Republic of Congo (Pointe-Noire Region)

A new genus of soft coral from the Republic of Congo is described, Complexum gen. n. Nine West African octocoral species previously described in the genus Alcyonium by Tixier-Durivault (1955) are referred to this new genus, and a new species is described and figured, Complexum pusillum sp. n. The new species is characterized by having encrusting growth form and abundant spiny clubs in the surface of the polyparium. It colonizes shallow calcareous rocky banks (5 to 20 m depth) existing in coastal water of the region of Pointe-Noire. Based on molecular phylogeny this new genus is well separated from Alcyonium species.
