Description of a new species of deep-water crab of the genus Homolodromia A. Milne-Edwards, 1880 from the northern Indian Ocean (Crustacea: Decapoda: Brachyura: Homolodromiidae)

ABSTRACT

Homolodromia rajeevani, a new species of deep-water homolodromiid sponge crab, is described from the northern Indian Ocean (Arabian Sea, depth 957 m, and Bay of Bengal, 645 m), and is the first record of the genus from the area. This species resembles the western Indian Ocean species, namely, Homolodromia bouvieri Doflein, 1904, in having 2 terminal spines on the propodi of the last two pereopods, but can be easily distinguished from the latter species by the inflated carapace, simple long setae on carapace and appendages, slender pseudo-rostral spines separated by a U-shaped base, and a slender arched dactylus of cheliped with maximum elevation at proximal part which bears broadly circular depressions with sparse setae. The most diagnostic character is the higher number of spines on the occlusal surfaces of propodal thumbs and dactyli of the pseudochela of the last two pereopods as compared to H. bouvieri. A key for the identification of the species under the genus Homolodromia is also provided.

The first record of genus Bruggmanniella (Diptera: Cecidomyiidae) from Taiwan with description of a new species inducing bud galls on Neolitsea parvigemma (Lauraceae)

The genus Bruggmanniella Tavares is newly discovered from Taiwan and Bruggmanniella brevipes sp. n. is described as new to science. This is the southernmost species of Bruggmanniella found in the Old World. Furthermore, the gall midge induces bud galls on Neolitsea parvigemma (Hayata) Kaneh (Lauraceae), an endemic species in Taiwan, and the plant genus Neolitsea is the third host genus of Lauraceae-associated Bruggmanniella in East Asia. The knowledge of its distribution and host information provide us to shed the light on evolutionary and biogeography issue of East Asian Bruggmanniella.www.zoobank.org/urn:lsid:zoobank.org:pub:820320EC-17BC-4E00-A401-2DBDA3EEE9C4     

A new species of Macquaridrilus (Annelida: Clitellata: Naididae) from subantarctic Campbell Island

Macquaridrilus mcmurtrieae n. sp. is described from Campbell Island. This resembles the only other species in the genus, Macquaridrilus bennettae Jamieson, 1968, in most aspects, but shows significant differences in the anatomy of its genitalia. In particular, the spermathecal pores are dorsal rather than lateral, the spermathecae lack diverticulae, the ejaculatory duct is more stout and muscular, the vas deferens is shorter relative to other organs and the anterior prostate is compact rather than elongate. The presence of a cuticular sperm canal appears to be an apomorphy for the genus. The new species was collected from streams and tarns across the island.

A new miniature species of geophilomorph centipede from the Ecuadorian Amazon rainforest (Chilopoda: Geophilomorpha: Ballophilidae)

A new miniature species of geophilomorph centipede, Ityphilus grismadoi sp. nov. (Chilopoda: Geophilomorpha: Ballophilidae) is fully described and illustrated on the basis of specimens collected in Yasuní Scientific Station and Jatun Sacha Biological Station, both located in the Ecuadorian Amazon. The new species is characterized by having the internal edge of the forcipular tarsungulum completely smooth, this trait being shared by six other Neotropical members of the genus Ityphilus Cook, 1899; and another species (I. cifuentesi Cupul Magaña, 2014) from the transition area between the Neotropical and Nearctic regions. Ityphilus grismadoi sp. nov. is distinguished from these seven species by the low number of leg-bearing segments (37, 39), and the very small body size (7–9 mm in length) and for a confident identification it is compared in detail with those having a roughly similar range of leg-bearing segments. This is the first record of the genus Ityphilus from Ecuador and the second report of a ballophilid centipede from the country (the other represented by Zygethmus pantenus Chamberlin, 1957). A key to the Neotropical members of Ityphilus with forcipular tarsungulum smooth (including I. cifuentesi) is also given.

Notes of the genus Chlorophila Semenow with descriptions of two new species from China (Coleoptera: Tenebrionidae: Lagriinae: Lagriini: Statiriina)

The genus Chlorophila Semenow, 1891 is reviewed with all known eight species worldwide in this present paper. Two new species, Chlorophila carinadorsum sp. n. and Chlorophila longicornia sp. n. are described. Four known species are described again from freshly collected specimens. The diagnostic characters of, and a key to all known eight species are provided.www.zoobank.org/urn:lsid:zoobank.org:pub:8DFE3353-9B83-4950-ACE9-918A42017C56.     

A new genus and species of Renaudarctidae (Heterotardigrada: Arthrotardigrada) from Ryukyu Archipelago,Japan

A new armoured marine tardigrade, Nodarctus hallucis gen. et sp. nov., is described from specimens collected from sandy beaches of Haterumajima, Ishigakijima and Okinawajima Islands, Ryukyu Archipelago, Japan. It is a member of the rare family Renaudarctidae, which is characterized by a stocky body with dorsal and ventral plates and stumpy legs with digits, claws and accessory filaments. However, the collected animals have prominent characters that differ from the two known species of the family: subdivided dorsal segmental plates I–III lacking lateral processes, an acute caudal spike, indented sensory plates, short spikes and peculiar papillae on legs I–III, basal spikes of legs IV and only two digits on legs IV. These differences justify the erection of a new genus and species for the animal. Morphological affinities with other marine taxa, the function of the leg papillae and the distribution pattern of the new species are discussed.http://zoobank.org/urn:lsid:zoobank.org:pub:041878AA-B437-45BF-80E3-32591D21D965     

Two new species of the tribe Hymenaphorurini Pomorski, 1996 (Collembola: Onychiuridae) from Korea

Two new species, Heteraphorura koreana sp. nov. and Psyllaphorura jirisana sp. nov., of the tribe Hymenaphorurini are described and illustrated based on materials from South Korea. Heteraphorura koreana sp. nov. belongs to the oriental species-group of the genus Heteraphorura, because of compound vesicles in the postantennal organ. This new species shares the same number of PAO with Heteraphorura pseudoseolagensis (Martynova, 1981) from Russia, but differs in pso dorsal formula and lateral teeth of claw. Psyllaphorura jirisana sp. nov. is similar to Psyllaphorura sensillifera.(Martynova, 1981) from the Russian Far East, but can be distinguished by shape of vesicles in PAO, dorsal s-chaetae on head and ratio AS/unguis. www.zoobank.org/urn:lsid:zoobank.org:pub:F854CBFD-06D0-4396-B8D9-62468B427111.     

Paradoxapseudes shimojiensis sp. nov. (Crustacea: Tanaidacea: Apseudidae) from a submarine limestone cave in Japan,with notes on its chelipedal morphology and sexual system

ABSTRACT

We describe Paradoxapseudes shimojiensis sp. nov. from a submarine limestone cave at Shimoji-jima Island, Ryukyu Islands, southwestern Japan. This species resembles five species (P. basibidens, P. bassoprofundo, P. bermudeus, P. edgari, and P. heroae, among 17 congeners) that bear a long pleotelson, but differs from them in having (i) a naked antennal article 1, (ii) the maxillipedal basis with one inner distal plumose seta, (iii) the chelipedal basis with one dorsodistal and one ventro-subproximal simple setae, (iv) the pereopod-1 basis with four dorsal simple setae longer than the width of the pereopod-1 basis, but without ventrodistal spiniform setae, (v) the pereopod-1 merus with three mid-inner ventral simple setae, and (vi) the pleopodal protopod with two inner plumose setae. We determined partial nucleotide sequences for the cytochrome c oxidase subunit I (COI) and 18S rRNA (18S) genes in P. shimojiensis for future use in DNA barcoding and phylogeny. Paradoxapseudes shimojiensis has serial ridges on the inner surfaces of the left and right chelipedal bases that quite resemble the stridulatory organs in harvestmen (Opiliones); by analogy, we speculate that these ridges may be stridulatory sound-producing organs. Two specimens had both a fully-developed marsupium and genital cone, suggesting that P. shimojiensis is simultaneously hermaphroditic.

First report of the family Palaeosetidae (Lepidoptera: Hepialoidea) from mainland China,with description of a new Ogygioses species and its phylogenetic position within the genus

The family Palaeosetidae is newly recorded from mainland China. A new species of the genus Ogygioses, O. maoershana sp. nov., is described from Guangxi Province, China. The adults, male and female genitalia, venation, head and legs structures are illustrated. Some ecological information and a key to all species of the genus are also provided. The phylogenetic position of the new species in the genus Ogygioses is inferred as intermediate between primitive O. luangensis Kristensen and other four derived species based on morphological characters and DNA barcodes sequences.www.zoobank.org/urn:lsid:zoobank.org:pub:D1FD6818-500A-4AE1-9F0B-13CB5A6E1ED4.     

A new species of the genus Pectinodonta Dall, 1882 (Gastropoda: Pectinodontidae) from the East China Sea

A new pectinodontid species collected from sunken wood in the East China Sea off Zhejiang Province, China, is described and assigned to the genus Pectinodonta Dall, 1882. This new species, Pectinodonta mazuae n. sp., has a medium sized shell with a fine sculpture; shell width about 72%–75% of shell length, height about 61%–66% of length, and each lateral tooth has 16 or 17 cusps. These features may be used to distinguish the new species from its congeners.

A key to species of the genus Senwot is presented.www.zoobank.org/urn:lsid:zoobank.org:pub:D7E79499-491E-4845-991B-0FE763A45162     

A remarkable new opsiine leafhopper genus (Hemiptera: Cicadellidae: Deltocephalinae) from Southern China,with notes on its phylogenetic position

A remarkable new genus of tribe Opsiini (Deltocephalinae), Yinformibus gen. nov. including Yinformibus menglaensis sp. nov. is described from Yunnan of China. The new genus is placed in the tribe Opsiini based on male adults having a pair of aedeagal shafts, each with its own gonopore. Partial 28S rDNA and Histone H3 sequences are provided for the new species, and a phylogenetic analysis based on these markers for Deltocephalinae retrieved from GenBank suggests Opsiini is monophyletic and supports the placement of Yinformibus gen. nov. in Opsiini. The molecular results placed the new genus in a clade comprising Hishimonus Ishihara, Opsius Fieber, and an undescribed genus from Zambia. Additionally, we also analysed the relationships of Yinformibus gen. nov. with other genera based on morphology.
