A New Species

Lebbeus sokhobio sp. nov. is described from abyssal depths (3303−3366 m) in the Kuril Basin of the Sea of Okhotsk. The related congeners are deep-water dwellers with a very distant distribution and very similar morphology. The new species is separated by minor morphological features, such as the armature of the rostrum and telson, meral spinulation of ambulatory pereiopods and the shape of the pleonal pleurae. This species is the deepest dwelling representative of the genus Lebbeus and the family Thoridae. A list of records of caridean shrimps recorded from abyssal depths below 3000 m is given.

A species of the genus Isoperla Banks, 1906, I. oncocauda Huo & Du, sp. nov. is described as new to science and is the first record for the family Perlodidae from the Tianmu Mountain Nature Reserve, Zhejiang Province of eastern coastal China. Both sexes of the new species are characterized by tergum 10 with a developed process. The partially extruded aedeagus of the male is membranous without conspicuous larger sclerites and with the ventral surface covered with dense scale-like and nail-shaped spines.

A New Species

The genus Smacigastes Ivanenko & Defaye, 2004 (Harpacticoida, Copepoda) is the most primitive genus in the family Tegastidae Sars, 1904, occurring in deep-sea chemosynthetic environments, such as hydrothermal vents, cold seeps, whale falls and wood falls. Our exploration of the Onnuri Vent Field, the sixth active hydrothermal vent system in the Central Indian Ridge, resulted in the discovery of a new species in the genus Smacigastes. A detailed morphological analysis of S. pumilasp. nov. reveals that it most resembles S. barti Gollner, Ivanenko & Martínez Arbizu, 2008, described from a hydrothermal vent in the East Pacific Ridge; the new species can be distinguished from the existing species by the 8-segmented female antennule, the absence of an abexopodal seta on the antennary basis, the mandibular exopod represented by a single seta and the exopod of the first leg with five setae. This is the first record of Smacigastes in the Indian Ocean. A dichotomous key to species of the genus Smacigastes worldwide is provided.

In this article we report on a hexactinellid sponge new to science, Tretopleura weijicus sp. nov., which was collected from the Weijia Seamount in the northwestern Pacific Ocean at a depth of 1995 m. Its blade-like and branching body form, the primary choanosomal framework consisting of multiaxial longitudinal strands without synapticula, and the presence of sceptrules suggest placement within the family Uncinateridae Reiswig, 2002, which is also supported by molecular phylogenetic evidence from COI and 16S sequences. The absence of swollen dermal spurs or regular pentactins and the presence of two types of discohexasters characterize it as a new species. More specimens should be collected to revise the generic characters.

A New Species

The whip spider genus Phrynichus (Phrynichidae, Amblypygi) is widely distributed in Africa, the Arabian Peninsula and Asia with a total of 17 species. No records, however, are known from several countries in the Middle East. Here we provide the first record of a whip spider from Iran (Ilam Province), with the description and illustration of a new species, Phrynichus persicus sp. n. This discovery fills a gap in the distribution of the group that is known from both sides of this biogeographically interesting region and is also the northernmost record of the family Phrynichidae. Moreover, all distribution records of the Phrynichus species are mapped (including the first verified record of the order from the United Arab Emirates), an updated key to the species of the deflersi and ceylonicus groups is provided, and Phrynichus andhraensis Bastawade, Rao, Maqsood Javed and Krishna, 2005 (India) is assigned to the ceylonicus group.

Rich Fauna

Considering the geographical location of China, a very rich fauna of water mites should be expected. Previously, seventeen families have been reported from China (Jin, 1997; Smit, 2002; Guo & Jin, 2005): Eylaidae Leach, 1815, Limnocharidae Grube, 1859, Hydryphantidae Piersig, 1896, Hydrodromidae Viets, 1936, Hydrachnidae Leach, 1815, Sperchontidae Thor, 1900, Lebertiidae Thor, 1900, Oxidae Viets, 1926, Teutoniidae Koenike, 1910, Limnesiidae Thor, 1900, Hygrobatidae Koch, 1842, Unionicolidae Oudemans, 1909, Pionidae Thor, 1900, Mideopsidae Koenike, 1910, Arrenuridae Thor, 1900 and Pontarachnidae Koenike, 1910. The species described in this paper belongs to the subgenus Dartia Soar, 1917 in the genus Nilotonia Thor, 1905 of the family Anisitsiellidae Koenike, 1910, which increases the number of known water mite families in the Chinese fauna to eighteen.

A new species of Tanaostigmodes (Hymenoptera: Chalcidoidea, Tanaostigmatidae) is described from China—Tanaostigmodes puerariae sp. nov. This is the first record of this family in China. This new species has potential as a biological control agent for control of kudzu, Pueraria lobate, in the U. S., because its preference for making leaf galls on kudzu. It was determined that the wasp has two generations per year, with the second generation overwintering as mature larvae in the gall on leaves that have dropped to the ground. Normally, only one wasp was found per gall, and a single kudzu leaf could have as many as 20 to 50 galls on its surface.
