Euastacus morgani sp. n., a new spiny crayfish (Crustacea, Decapoda, Parastacidae) from the highland rainforests of eastern New South Wales, Australia

Euastacus morgani sp. n., is described from a highland, rainforest site in Bindarri National Park, in eastern New South Wales, Australia. Euastacus morgani is found living sympatrically with two more common species, Euastacus dangadi Morgan, 1997 and Euastacus neohirsutus Riek, 1956. Systematically, the species belongs in the 'simplex' complex of the genus that includes Euastacus simplex Riek, 1956, Euastacus clarkae Morgan, 1997, Euastacus maccai McCormack and Coughran 2008 and E. morgani. This new species differs from its nearest congenor, Euastacus simplex, in having three mesial carpal spines. A key to the 'simplex' complex is presented.     

Cherax (Astaconephrops) pulcher,a new species of freshwater crayfish (Crustacea,Decapoda, Parastacidae) from the Kepala Burung (Vogelkop) Peninsula,Irian Jaya (West Papua), Indonesia

A new species, Cherax (Astaconephrops) pulcher sp. n., from Hoa Creek, close to the village Teminabuan in the southern-central part of the Kepala Burung (Vogelkop) Peninsula, West Papua, Indonesia, is described, figured and compared with the morphologically closest species, Cherax boesemani Lukhaup & Pekny, 2008.     

A new genus and species of dalodesmid millipede from New South Wales,Australia (Diplopoda,Polydesmida, Dalodesmidae)

Cernethia inopinata gen. n., sp. n. is described from highland New South Wales. Like other dalodesmids the new species has numerous sphaerotrichomes on the legs of adult males, but Cernethia inopinata sp. n. shares several character states with Tasmanian species in the genera Noteremus Mesibov, 2009, Paredrodesmus Mesibov, 2003 and Procophorella Mesibov, 2003, which lack sphaerotrichomes and have not yet been assigned to family within the suborder Dalodesmoidea.     

Cherax snowden,a new species of crayfish (Crustacea,Decapoda, Parastacidae) from the Kepala Burung (Vogelkop) Peninsula in Irian Jaya (West Papua), Indonesia

A new species, Cherax snowden sp. n., from the Oinsok River Drainage, Sawiat District in the central part of the Kepala Burung (Vogelkop) Peninsula, West Papua, Indonesia, is described, figured and compared with the closest related species, Cherax holthuisi Lukhaup & Pekny, 2006. This species is collected and exported for ornamental purposes and its commercial name in the pet trade is “orange tip” or “green orange tip”. Both species may be easily distinguished morphologically or by using sequence divergence, which is substantial, for considering Cherax snowden sp. n. to be a new species.     

Structural alterations in the male reproductive system of the freshwater crayfish, Cherax quadricarinatus (Decapoda, Parastacidae)

No diseases affecting reproductive performance have been previously reported in freshwater crayfishes. This study aims to characterise one reproductive system abnormality found in males of Cherax quadricarinatus reared in captivity. Fifteen adult males of C. quadricarinatus (70-110 g) were purchased from San Mateo S.A. farm (Entre Ríos, Argentina) each season during 2007. Macroscopic analysis showed that 26.6% of the animals sacrificed in winter presented brownish distal vasa deferentia. Histological analysis showed different levels of structural abnormality in the epithelium of the vasa deferentia and spermatophore. Granular and hyaline haemocytes were identified within the vasa deferentia but no significant differences were found in the sperm count between normal and brownish vas deferens. Histological analysis of the crayfishes sacrificed in autumn also showed these modifications in 22% of the animals, however, they did not show the brownish colour under macroscopic analysis. The similarities between the male reproductive system syndrome in shrimps and the abnormalities found in C. quadricarinatus are notable. An unspecific response to thermic stress is a possible explanation of these structural alterations.

Aphelenchoides microstylus n. sp. and Seinura onondagensis n. sp. (Nemata: Aphelenchina) from New York

Aphelenchoides microstylus n. sp. and Seinura onondagensis n. sp., a nematode predator, are described from dead Scots pine (Pinus sylvestris L.) in Onondaga County, New York. Females of A. microstylus are 370 to 485 µm long. The body is slender and tapers posteriorly to an amucronate, pointed terminus. The head is continuous with the body, and lips bear a stylet guide. Diagnostic characters of females are three incisures in the lateral field, a short stylet (6-7.5 µm) with small basal knobs, a single row of oocytes, and a long postuterine sac (25-50 µm). Males are characterized by small spicules (10-11µm); two pairs of post-anal, subventral papillae; and a single row of spermatocytes. A bursa and gubernaculum are absent. Seinura onondagensis females are characterized by a body of moderate length (475-595 µm), finely annulated cuticle, and a slightly set-off head. Diagnostic characters are four incisures in the lateral field, long stylet without basal knobs (17-22 µm), single row of oocytes, and presence of a postuterine sac (14-38 µm). Males are unknown. The monospecific genus Indaphelenchus is proposed as a synonym of Seinura, and S. siddiqii n. comb. is proposed for the only species, I. siddiqii.     

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.     

Lithobius (Monotarsobius) monoforaminis sp. n., a new species of lithobiid centipede from central China (Chilopoda, Lithobiomorpha, Lithobiidae)

The present paper describes a new species Lithobius (Monotarsobius) monoforaminissp. n. (Lithobiomorpha: Lithobiidae) recently discovered from Shaanxi and Shanxi provinces, Central China. Morphologically it resembles Lithobius (Monotarsobius) minimus Farzalieva, 2006 from Eastern Kazakhstan, but could be well distinguished from the latter having only one pore on the coxae of legs 12-15 and different plectrotaxy, and by lacking a wart on the male tibia 15. A key to the Chinese Lithobius (Monotarsobius) species is presented.     

Pachyseris inattesa sp. n. (Cnidaria,Anthozoa, Scleractinia): a new reef coral species from the Red Sea and its phylogenetic relationships

A new scleractinian coral species, Pachyseris inattesa sp. n., is described from the Red Sea. Despite a superficial resemblance with some species in the agariciid genus Leptoseris with which it has been previously confused, P. inattesa sp. n. has micro-morphological characters typical of the genus Pachyseris. This genus, once part of the Agariciidae, is comprised of five extant species and is widely distributed throughout the tropical Indo-Pacific. It is currently incertae sedis as a result of recent molecular analysis and appears to be closely related to the Euphylliidae. A molecular phylogenetic reconstruction including P. inattesa sp. n., the genus type species P. rugosa, and P. speciosa, all present in the Red Sea, was performed using the mitochondrial intergenic spacer between COI and 16S-rRNA. The results confirm that P. inattesa sp. n. is a monophyletic lineage closely related to the other Pachyseris species examined.     

Filenchus flagellicaudatus n. sp. and Lelenchus schmitti n. sp. (Nemata: Tylenchidae) from Molokai,Hawaii

Filenchus flagellicaudatus n. sp. and Lelenchus schmitti n. sp. are described from Pepe''opae bog on Molokai, Hawaii. Filenchus flagellicaudatus n. sp. is distinguished from all other Filenchus spp. by stylet length (10 µm), robust metacorpus, elongated basal bulb, and extraordinarily long, whip-like tail (c = 2.6, c'' = 31.8). Lelenchus schmitti n. sp. differs from other Lelenchus spp. by its shorter body length, weak dorso-ventral compression of the head region, and a more posterior vulva (V = 49-52). The spacious amphid pocket is introduced as a useful character for the differentiation of Lelenchus spp. from other Tylenchidae.     

Sinocorophium hangangense sp. n. (Crustacea, Amphipoda, Corophiidae), a new species from Korea, with a key to the genus Sinocorophium

A new species of the corophiid gammaridean amphipod belonging to the genus Sinocorophium Bousfield & Hoover was collected from the lower reaches of the Han River in Gyeonggi-do, Korea. A relatively large body size and morphology of the uropods 1 and 3 are the major characteristics which serve to distinguish the new species from its congeners. The new species is fully illustrated and extensively compared with related species. A key to the species of (Sinocorophium is also provided.     

Pseudofornicia gen. n. (Hymenoptera,Braconidae, Microgastrinae), a new Indo-Australian genus and one new species from Vietnam

Pseudofornicia gen. n. (Hymenoptera: Braconidae: Microgastrinae) is described (type species: Pseudofornicia nigrisoma sp. n. from Vietnam) including three Oriental (type species, Pseudofornicia flavoabdominis (He & Chen, 1994), comb. n. and Pseudofornicia vanachterbergi Long, (nom. n. for Fornicia achterbergi Long, 2007; not Fornicia achterbergi Yang & Chen, 2006) and one Australian species (Pseudofornicia commoni (Austin & Dangerfield, 1992), comb. n.). Keys to genera with similar metasomal carapace and to species of the new genus are provided. The new genus shares the curved inner middle tibial spur, the comparatively small head, the median carina of the first metasomal tergite and the metasomal carapace with Fornicia Brullé, 1846, but has the first tergite movably joined to the second tergite and the third tergite 1.1–1.6 × as long as the second tergite medially and is flattened in lateral view. One of the included species is a primary homonym and is renamed in this paper.     

Steinernema biddulphi n. sp., a New Entomopathogenic Nematode (Nematoda: Steinernematidae) from South Africa

A new species of entomopathogenic nematode (EPN), Steinernema biddulphi n. sp., was isolated from a maize field in Senekal, Free State Province of South Africa. Morphological and molecular studies indicated the distinctness of S. biddulphi n. sp. from other Steinernema species. Steinernema biddulphi n. sp. is characterized IJs with average body length of 663 μm (606–778 μm), lateral fields with six ridges in mid-body region forming the formula 2,6,2. Excretory pore located anterior to mid-pharynx (D% = 46). Hyaline layer occupies approximately half of tail length. Male spicules slightly to moderately curved, with a sharp tip and golden brown in color. The first generation of males lacking a mucron on the tail tip while the second generation males with a short filamentous mucron. Genital papillae with 11 pairs and one unpaired preanal papilla. The new species is further characterized by sequences of the internal transcribed spacer (ITS) and partial 28S regions (D2-D3) of the ribosomal DNA (rDNA). Phylogenetic data show that S. biddulphi n. sp. belongs to the “bicornutum” clade within the Steinernematidae family.     

Leinendera achaeta sp. n., a new species of robber fly from Brazil (Diptera,Asilidae, Asilinae)

The third species of the Neotropical genus Leinendera Carrera, 1945, Leinendera achaeta sp. n., is described from Rio Grande do Sul state, Brazil. The habitus, wing and male terminalia are described and illustrated, and a key to the three Brazilian species is provided.     

A new genus and species (Cornucollis gen. n. masoalensis sp. n.) of praying mantis from northern Madagascar (Mantodea,Iridopterygidae, Tropidomantinae)

An examination of Malagasy specimens accessed within the Muséum national d’Histoire naturelle, Paris, France, produced a praying mantis (Insecta: Mantodea) of an undescribed genus and species. An investigation of the internal and external morphology, in addition to its collection locality, revealed that this specimen belongs to the Iridopterygidae subfamily Tropidomantinae. Furthermore, the specimen’s unique combination of characters justified the creation of a new genus. Geographic distributional records and external morphological character evidence are presented for Cornucollis gen. n. masoalensis sp. n. We provide a dichotomous key of the Tropidomantinae and Nilomantinae genera distributed within Madagascar. High-resolution images, illustrations of morphological characters, natural history information, and measurement data are presented.
