Melitid amphipods from the Gulf of Thailand,with a description of Dulichiella pattaniensis,a new species

Two species of melitid amphipod were collected from the Gulf of Thailand. Dulichiella pattaniensis is new to science, and Melitalati latiflagella Ren & Andres, 2012 has not been previously reported from Thai Waters. Dulichiella pattaniensis is characterized by male gnathopod 2 distolateral crown with 4 spines; pleonite/urosomite formula 7-7-7-5-6-2; pereopod 5-7 dactylus with 2 accessory spines. This combination of characters has not been recorded previously in the Dulichiella. The characters of the specimens are described and illustrated.

On the spider genus Arboricaria with the description of a new species (Araneae,Gnaphosidae)

The spider genus Arboricaria Bosmans, 2000 is redefined and an updated diagnosis given. The differences between Arboricaria and Micaria Westring, 1851 are discussed in detail. A key to all five species of the genus is provided. One new species, Arboricaria zonsteini sp. n. (♂♀), is described based on specimens from Kyrgyzstan and Azerbaijan. One new synonym is proposed: Arboricaria koeni Bosmans in Bosmans & Blick, 2000, syn. n. is assigned to Arboricaria sociabilis Kulczyński in Chyzer & Kulczyński, 1897. Data on the distribution of Arboricaria in Russia and adjacent countries are presented with references to the papers on local spider faunas.     

The millipede genus Caucasodesmus Golovatch, 1985, with the description of a new species from the Crimea, Ukraine (Polydesmida, Diplopoda, Trichopolydesmidae)

The hitherto monotypic genus Caucasodesmus is new to the Ukrainian list due to the discovery of Caucasodesmus tauricussp. n. in a cave in the Crimea. The new species is easily distinguished from Caucasodesmus inexpectatus Golovatch, 1985, the type, and only other, known species of this genus, in the abundantly setose collum and following metaterga, and more elaborate gonopods. The status of Caucasodesmus, which shows in the superfamily Trichopolydesmoidea where it definitely belongs such evident generic-level apomorphies as the absence of bacilliform sensilla on antennomeres 5 and 7, of a cannula on the gonocoxite, and of a seminal groove on a biramous gononod telopodite (apparently, both latter characters are functionally correlated to each other), is refined by formally reassigning it to the family Trichopolydesmidae.     

The genus Mesadenella (Orchidaceae) in Colombia with description of two new species

Two new species of Mesadenella, M. longipetiolata and M. bicordata, are described, illustrated and placed within the key to identification of Colombian Mesadenella species. The information about distribution and ecology of the new species as well as brief taxonomic notes are provided.     

Notes on the genus Microcriodes Breuning,with description of a new species from Xizang,China (Coleoptera,Cerambycidae, Lamiinae,Batocerini)

The genus Microcriodes Breuning is newly recorded from China upon the discovery of M. sikkimensis Breuning, 1943 and M. wuchaoi sp. n. from Motuo, Southeast Xizang. Illustrations of the habitus, genitalia including non-everted endophallus, as well as diagnostic features are provided.     

A new species of the genus Haba Semenov, 1954 (Hymenoptera: Chrysididae) from Iran,with a key to species

A new species of the genus Hydrodroma Koch, 1837 (Acari, Hydrachnidia, Hydrodromidae), with a key to the hitherto known six species of the genus in Australia

The genus Hydrodroma Koch, 1837 in Australia consists of six species, the newly described Hydrodroma meridionalissp. n. included. The new species is described from 45 sampling sites from running waters in Queensland, Victoria, New Southern Wales, Western Australia, Northern Territory and South Australia. Furthermore, a key for the identification of species of Hydrodroma occurring in Australia is given.     

Neurotransmitters of motor neurons in the stomatogastric ganglion of an isopod crustacean, Ligia exotica

Neurotransmitters of motor neurons in the foregut muscles of an isopod Ligia exotica were identified by recording changes in membrane potential to exogenously applied glutamate and acetylcholine. The effects of antagonists, tubocurare and joro spider toxin, on excitatory junctional potentials evoked by nerve stimulation and by iontophoretic application of glutamate and acetylcholine provided additional evidence for identification. The junctional receptors were desensitized by putative neurotransmitters. Glutamate is a candidate as an excitatory neurotransmitter at the neuromuscular junctions in intrinsic muscles of the gastric mill and pylorus, and acetylcholine is a candidate in the extrinsic muscles of the gastric mill and cardiopyloric valve.     

Notes on the genus Harmonicon F.O.P.-Cambridge, 1896 (Araneae, Dipluridae) with description of a new species from French Guyana

Information on the genus Harmonicon F.O.P.-Cambridge, 1896, a key to the species and a new diagnosis differing from the one in Maréchal and Marty (1998) are provided. A new species is described: Harmonicon oiapoqueae differing from other species of the genus by the morphology of the posterior sternal sigilla, the more recurved, inverted U–shaped fovea, the amount and arrangement of maxillary cuspules, a single row of teeth on the claws of the palpal tarsus, longer and more slender legs III and IV in females, longer embolus, thinner bulb, and longer, more slender legs in males. The status of the putative junior synonyms of Harmonicon, Pseudohermachura Mello-Leitão, 1927 and Prosharmonicon Mello-Leitão, as well as the two species formerly assigned to Harmonicon, Harmonicon nigridorsi Mello-Leitão, 1924 and Harmonicon riveti Simon, 1903, is discussed.     

A new species of the genus Helcogramma (Blenniiformes, Tripterygiidae) from Taiwan

A new species of triplefin fish (Blenniiformes: Tripterygiidae), Helcogramma williamsi, is described from six specimens collected from southern Taiwan. This species is well distinguished from its congeners by possessing 13 second dorsal-fin spines; third dorsal-fin rays modally 11; anal-fin rays modally 19; pored scales in lateral line 22-24; dentary pore pattern modally 5+1+5; lobate supraorbital cirrus; broad, serrated or palmate nasal cirrus; first dorsal fin lower in height than second; males with yellow mark extending from anterior tip of upper lip to anterior margin of eye and a whitish blue line extending from corner of mouth onto preopercle. Comparisons and a diagnostic key are provided for the species of Helcogramma now known from Taiwan: Helcogramma fuscipectoris, Helcogramma inclinata, Helcogramma striata, Helcogramma trigloides, and the newly recorded, Helcogramma rhinoceros.
