On some oonopidae from japan and formosa (araneae)

Abstract

Gamasamorpha cataphracta KARSCH, 1881 is redescribed on the types; synonym of it is Oonops corticalis BÖSENBERG & STRAND, 1906 (types examined; new synonymy). Pseudotriaeris n. gen. is described; type: Gamasomorpha karschi BÖSENBERG & STRAND, 1906), of uncertain affinities this genus is peculiar by the extreme complexity of the ♂-palp. Pseudotriaeris karschi (BÖSENBERG & STRAND, 1906) comb. nov. is redescribed on the types. From Formosa are recorded or described: Gamasomorpha cataphracta KARSCH; Ischnothyreus f ormosus n. sp. (♂♀ type. loc.: Akau), near to I, narutomii (NAKATSUDI, 1942), distinguishable from this and the other species by the genitalia; Opopaea sauteri n. sp. (♂, ♀ unknown; typ. loc.: Takao), near to O, syarakui (KOMATSU, 1967) comb. nov. (described as Gamasomorpha), distinguishable by the genitalia. Some considerations are made over taxonomical problems in the genera Gamasomorpha and Opopaea. © 1974, Arachnological Society of Japan. All rights reserved.
