Three new species of Opiliones are delimited and described from central and northern Taiwan based on morphological and molecular evidence. Pseudogagrella dorsomaculata sp. nov., collected from the Dasyueshan Forest Recreation Area, Heping, Taichung, resembles P. andoi Suzuki 1977, but can be recognized by the different pattern of the first abdominal tergite and the morphology of the penile grans. Pseudogagrella nigridorsa sp. nov., collected from the Lalashan National Forest Sanctuary, Fusing, Taoyuan, resembles P. arishana Suzuki 1977, but can be recognized by the different pattern of legs and the morphology of the penile stylus. Pseudogagrella sauteri sp. nov., also collected from the Dasyueshan Forest Recreation Area, resembles P. cyanea (Roewer 1915) and P. taiwana Suzuki 1977, but can be distinguished by the morphology of the alate part of the penis. Molecular evidence from mitochondrial 16S rDNA and cytochrome oxidase subunit I (COI) supports the identity of the three new species.

Abstract A new species of freshwater crab of the genus Teretamon Yeo & Ng, 2007, Teretamon husicum sp. nov., is described here from Husa Town, Longchuan County, Dehong Prefecture, Yunnan Province, China. Teretamon husicum sp. nov. can be distinguished from other species by a suite of morphological characters, including a bilobed frontal margin, smooth posterolateral regions, and a broadly rounded dorsal flap on the G1 terminal segment. An updated identification key for the species of the genus Teretamon is provided.

A new species of freshwater crab of the genus Hydrothelphusa A Milne-Edwards, 1872, is described based on specimens collected from a forested region of southeastern Madagascar. Hydrothelphusa vencesi n. sp. is clearly distinguished from its congeners by its distinctive first gonopod (G1) with a terminal article that is in the form of a long straight-sided cone, and by a dorsal membrane at the segment junction of G1 that is broad and diamond-shaped. A key is provided to separate the five species of Hydrothelphusa.

A New Species

A new species of pseudothelphusid crab, Allacanthos yawi n. sp., from the Río Volcán drainage, Puntarenas Province, southern Costa Rica, Central America, is described and illustrated. This is the second species to be assigned to the genus Allacanthos Smalley, 1964. The new species is distinguished by its congener by having a first gonopod with a mesiolaterally flattened distal portion, a concave and nearly smooth subdistal portion of the lateral and cephalic sides, a narrow marginal process with a nearly straight distal border, and a lateral lobe with a sharp tip on the apex. An amended diagnosis for Allacanthos is provided.

A New Species

Abstract The identity of the potamid freshwater crab, Indochinamon manipurense (Alcock, 1909) from the state of Manipur in northeast India, is clarified based on an examination of the type specimens. The species is redescribed and a lectotype designated. Specimens from the same region previously referred to this species were compared to the types of I. manipurense and shown to belong to a new species of Potamiscus Alcock, 1909, instead. The new species, Potamiscus takedai sp. nov., can easily be separated from I. manipurense by the characters in the carapace, third maxilliped, male pleon, male gonopods, and female vulvae. Potamiscus takedai sp. nov. can be differentiated from congeners mainly by the strongly bent terminal segment of the male first gonopod and a relatively shorter distal segment of the male second gonopod.

A New Species

A new species of the genus Neoperla (Plecoptera, Perlidae), N. yingshana Chen & Du sp. nov. from the Wujiashan National Forest Park, Hubei Province of central China is described, illustrated and compared with similar taxa. The new species is characterized by the aedeagal tube long with an upcurved, finger-like spinulose lobe subapically, and by the aedeagal sac plump, gradually tapering to a blunt tip with dense spinules on ventral surface and granules surrounding sac apex.
