  Beneath the surface: A new northern species of Trogloraptor (Araneae: Trogloraptoridae), genetic diversity and natural history Abstract We present a morphological description of a recently discovered species of spider in the family Trogloraptoridae from the Columbia River Gorge in northwestern Oregon. The family was previously monotypic (Trogloraptor marchingtoni) and only known from populations near the southwestern Oregon—northern California border. Trogloraptor tulishpun sp. nov. retains the key family synapomorphy, distinctive subsegmented raptorial tarsi, and an oblique membranous division of the basal segment of the anterior lateral spinnerets. Trogloraptor tulishpun is distinguished from T. marchingtoni by its color pattern, clypeal height, vulvar and palp structure. We have found T. tulishpun in four localities in the Columbia River Gorge, which show little mitochondrial sequence divergence from one another, but are highly genetically distinct from T. marchingtoni.

Isometrus wenjieae sp. n., a new species of the subgenus Reddyanus from China (Scorpiones: Buthidae)

Abstract. – Isometrus (Reddyanus) wenjieae sp. n. from Guangdong Province (China), is described and properly illustrated. The new species shows a combination of distinctive morphological characters: (i) a total length ranging from 30.6 mm to 43.9 mm, (ii) pectinal teeth count 13 to 16 in males and 14 to 15 in females, (iii) fulcra present (iv) legs with markings, (v) ventral side of the subaculear tooth with two granules. A distribution map for the members of subgenus Reddyanus in China is equally provided.
