Four new species of Unixenus Jones, 1944 (Diplopoda,Penicillata, Polyxenida) from Australia

Unixenus carnarvonensis sp. n., Unixenus corringlensis sp. n., Unixenus barrabaensis sp. n. and Unixenus myallensis sp. n. are described from Australia. A revised diagnosis of Unixenus karajinensis and new details on the distribution of the species are given. A key is presented to 10 of all 11 currently known species of the genus.     

A new species of Dystacta Saussure, 1871 from Nyungwe National Park,Rwanda (Insecta,Mantodea, Dystactinae)

A recent targeted entomological survey in the Republic of Rwanda has produced two conspecific male and female specimens of an undescribed species of praying mantis (Mantodea). The specimens were collected in Nyungwe National Park in May of 2013. The species is closest morphologically to Dystacta alticeps (Schaum, 1853). Therefore, a new species is described, Dystacta tigrifrutex sp. n., along with the first instar nymphs and ootheca. In addition, the previously monotypic genus Dystacta Saussure, 1871 is re-described to provide a broader definition of the genus group. Habitus images, measurement data, a key to species, natural history information, and locality data are provided.     

Revealing the diversity of a once small taxon: the genus Selenoribates (Acari,Oribatida, Selenoribatidae)

Three new intertidal oribatid species, Selenoribates elegans sp. n., Selenoribates quasimodo sp. n. and Selenoribates satanicus sp. n. are described from the archipelago of Bermuda. Selenoribates elegans sp. n. is characterized by its slender body shape, Selenoribates quasimodo sp. n. possesses a hunchback in lateral view and Selenoribates satanicus sp. n. exhibits two horn-like projections on its anterior gastronotic region. Based on these new findings, the number of Selenoribates species doubled at once and the distribution of this genus, formerly limited to the Mediterranean and the Red Sea, includes now occurrences in the Atlantic and Indo-pacific Ocean as well. The morphology of Selenoribates quasimodo sp. n. and Selenoribates satanicus sp. n. deviates conspicuously from the other known members of Selenoribates, thus indicating that not only the number of species but also the anatomy of this genus is more diverse than formerly supposed. Nymphs of Selenoribates quasimodo sp. n. show an interesting case of ontogenetic neotrichy, with gastronotic setae being duplicated with each moult.     

The semi-aquatic freshwater earthworms of the genus Glyphidrilus Horst, 1889 from Thailand (Oligochaeta,Almidae) with re-descriptions of several species

The semi-aquatic freshwater earthworm genus Glyphidrilus Horst, 1889 from Thailand was investigated based on extensive recent collecting. The species in this genus were characterized by their external and internal morphological characters of the location of wings, genital openings, genital organ structures and their locations, as well as the dimensions of body length and number of segments. Several type specimens were compared with both previous and newly collected materials. Ten new species are described from several river systems in Thailand; as Glyphidrilus borealis sp. n., Glyphidrilus chaophraya sp. n., Glyphidrilus chiensis sp. n., Glyphidrilus huailuangensis sp. n., Glyphidrilus kratuensis sp. n., Glyphidrilus quadratus sp. n., Glyphidrilus trangensis sp. n., Glyphidrilus wararamensis sp. n., Glyphidrilus vangthongensis sp. n. and Glyphidrilus vesper sp. n. Each species is endemic to a single river system. All 26 previously described species are re-described, and eight lectotypes have been designated. An identification key and a morphological comparison summary are provided.     

A new species of the genus Arhynchite (Annelida,Echiura) from sandy flats of Japan,previously referred?to as Thalassema owstoni Ikeda, 1904

A new echiuran, Arhynchite hayaoi sp. n., is described from newly collected specimens from sandy flats of the Seto Inland Sea, Japan, together with many museum specimens, including those once identified as Thalassema owstoni Ikeda, 1904 or Arhynchite arhynchite (Ikeda, 1924). The new species is clearly distinguishable from its congeners by the smooth margin of gonostomal lips and lack of rectal caecum. Brief references are also made to the morphological distinction between the new species and Thalassema owstoni, originally described from the deep bottom on the Japanese Pacific coast.     

Two new species and new records of the genus Spinolyprops Pic, 1917 from the Oriental Region (Coleoptera,Tenebrionidae, Lupropini) *

Two new species of the genus Spinolyprops Pic, 1917 (Tenebrionidae, subfamily Lagriinae Latreille, 1825) are described from Thailand and China (Spinolyprops cribricollis sp. n., Spinolyprops thailandicus sp. n.). The species characters within the genus are discussed, photographs of all seven Oriental species are added, a species key for the Oriental species is compiled, and a map with the distributional patterns is provided.     

A new species of Euscorpius Thorell, 1876 (Scorpiones,Euscorpiidae) from Marmara Region of Turkey

A new species of the genus Euscorpius Thorell, 1876 is described based on specimens collected from Bursa Province, in Marmara Region of Turkey. It is characterized by a mesotrichous trichobothrial pattern (Pv= 8, et= 6, em=4, eb= 4), medium size and light coloration. Euscorpius (Euscorpius) rahsenae sp. n. is the second species of the subgenus Euscorpius recognizedin Turkey.

Five new apterous species of the genus Lathrobium Gravenhorst, 1802 from Baishanzu Natural Reserve, Zhejiang, East China, Lathrobium baishanzuense sp. n., Lathrobium immanissimum sp. n., Lathrobium obstipum sp. n., Lathrobium pilosum sp. n. and Lathrobium tangi sp. n., are described and illustrated. The Lathrobium fauna of the study region is represented by two distinct lineages.     

A revision of the Afrotropical spider genus Cambalida Simon, 1909 (Araneae,Corinnidae)

The non-mimetic Afrotropical spider genus Cambalida Simon, 1909, placed within a subfamily of predominantly ant-mimicking spiders (Araneae: Corinnidae: Castianeirinae), is revised. Three species are transferred from Castianeira Keyserling, 1879 to Cambalida: Cambalida deminuta (Simon, 1909), comb. n., Cambalida fulvipes (Simon, 1896), comb. n. and Cambalida loricifera (Simon, 1885), comb. n.. A fourth species, Cambalida fagei (Caporiacco, 1939), comb. n., is transferred from Brachyphaea Simon, 1895 to Cambalida. Two species, Castianeira depygata Strand, 1916, syn. n. and Cambalida mestrali Lessert, 1921, syn. n., are considered junior synonyms of Cambalida fulvipes. The males of Cambalida deminuta and Cambalida loricifera are redescribed and their unknown females are described for the first time. The female and male of Cambalida fulvipes and Cambalida coriacea Simon, 1909 are also redescribed. The type material of the type species of the genus, Cambalida insulana Simon, 1909 from Pagalu (Annobon) Island, is lost, and only immature specimens have been subsequently collected from a nearby island. The species is regarded as a nomen dubium until fresh adult material can be collected. A replacement name, Cambalida simoni nom. n. is proposed for Cambalida fulvipes Simon, 1909, the latter being a secondary junior homonym of Cambalida fulvipes (Simon, 1896). The type material of this species is also lost and it is too considered nomen dubium. The following new species are described: Cambalida compressa sp. n. from West Africa, Cambalida dippenaarae sp. n. from southern Africa, Cambalida griswoldi sp. n. and Cambalida lineata sp. n. from Madagascar, and Cambalida unica sp. n. from Cameroon. Notes are provided on the biology of each species and the distribution of the genus in the Afrotropical Region.     

Description and phylogeny of Namalycastis jaya sp. n. (Polychaeta,Nereididae, Namanereidinae) from the southwest coast of India

Namalycastis jaya sp. n. (Polychaeta: Nereididae: Namanereidinae)is described from the southern coast of Kerala in southwest India. One important characteristic feature of the species is the lack of notochaetae in all parapodia, a characteristic that it shares with at least two other species, Namalycastis elobeyensis Glasby, 1999and Namalycastis hawaiiensis Johnson, 1903. It differs from Namalycastis elobeyensis by virtue of its smaller antennae, unequal eye size, bilobed acicular neuropodial ligule and multi-incised pygidium rim. Moreover, it differs from Namalycastis hawaiiensis by having fewer teeth on the serrated blades of the sub-neuroacicular falciger in chaetiger 10, and by possessing finely serrated falcigers in posterior segments. Beyond morphological analyses, molecular phylogenetics was used for the first time for Namalycastis to support population monophyly and recognition of the new species.The analysis, using both mitochondrial and nuclear data, corroborated the morphological analysis in suggesting that our specimens represent an as yet undescribed species, Namalycastis jaya sp. n., which forms a monophyletic group among the sampled nereidid taxa. Finally, a taxonomic key for Namalycastis species recorded from the Indian region is provided.     

A new species of Scelidopetalon Delkeskamp (Coleoptera,Erotylidae) from China with a?key?to?world species of the genus

Mestus cruciatus,a new delphacid species from southwest China with some remarks on the genus (Hemiptera,Fulgoromorpha, Delphacidae)

A new delphacid (Hemiptera, Fulgoromorpha, Delphacidae) species, Mestus cruciatus sp. n. is described based on specimens from Yunnan Province, China. Habitus photos and illustrations of male genitalia are provided. The Mestus species and phylogenetic arrangement of this genus is discussed. A key to the species of Mestus is also provided.     

Description and scanning electron microscopic observation of a new species of the genus Polycopetta (Crustacea,Ostracoda, Cladocopina) from an interstitial habitat in Japan

A new species of the genus Polycopetta Chavtur, 1981, Polycopetta quadrispinata sp. n. is described from the interstitial environment of Mihomasaki Beach in Japan. These observations showed some morphological peculiarities of Polycopetta quadrispinata sp. n. compared with its congeners; Polycopetta monneroni Chavtur, 1979, Polycopetta curva Chavtur, 1979, Polycopetta bransfieldensis (Hartmann, 1987), and Polycopetta pax Kornicker and Harrison-Nelson, 2005. Three characteristics are described for the first time: (1) a seta with serrated tip on the male antennula, (2) the endopodite of the fifth limb consisting of two podomeres, (3) the long spermatozoa in the male posterior body. More detailed observations of the type species are needed in order to update the generic diagnosis.

Phylogeny and host-plant relationships of the Australian?Myrtaceae leafmining moth genus Pectinivalva (Lepidoptera,Nepticulidae), with?new?subgenera and species

The phylogeny of the mainly Australian nepticulid genus Pectinivalva Scoble, 1983 is investigated on the basis of morphology, and a division into three monophyletic subgenera is proposed on the basis of these results. These subgenera (Pectinivalva, Casanovula Hoare, subgen. n. and Menurella Hoare, subgen. n. ) are described and diagnosed, the described species of Pectinivalva are assigned to them, and representative new species are described in each: Pectinivalva (Pectinivalva) mystaconota Hoare, sp. n., Pectinivalva (Casanovula) brevipalpa Hoare, sp. n., Pectinivalva (Casanovula) minotaurus Hoare, sp. n., Pectinivalva (Menurella) scotodes Hoare, sp. n., Pectinivalva (Menurella) acmenae Hoare, sp. n., Pectinivalva (Menurella) xenadelpha Van Nieukerken & Hoare, sp. n., Pectinivalva (Menurella) quintiniae Hoare & Van Nieukerken, sp. n., and Pectinivalva (Menurella) tribulatrix Van Nieukerken & Hoare, sp. n. Pectinivalva (Menurella) quintiniae (from Quintinia verdonii, Paracryphiaceae) is the first known member of the genus with a host-plant not belonging to Myrtaceae. Pectinivalva (Menurella) xenadelpha from Mt Gunung Lumut, Kalimantan, Borneo, is the first pectinivalvine reported from outside Australia. Keys to the subgenera of Nepticulidae known from Australia, based on adults, male and female genitalia, and larvae, are presented. Host-plant relationships of Pectinivalva are discussed with relation to the phylogeny, and a list of known host-plants of Pectinivalva, including hosts of undescribed species, is presented. DNA barcodes are provided for most of the new and several unnamed species.
