Key to females of Atrichopogon described from Taiwan

The Atrichopogon fauna of Taiwan, in addition to the species redescribed and interpreted above, includes A. monticolus Tokunaga, 1940 a (p. 271, Taihoku, female), A. kagiensis Tokunaga, 1940 a (p. 270, Taihoku, male) and A. flavidus Kieffer, 1921 . The latter species was briefly described by Kieffer from Philippines (Kieffer 1921) and subsequently recorded from Taihoku by Tokunaga (1940b). Actually it is a doubtful species which has no diagnostic characters and its report from Taiwan is doubtful. Types in SDEI are not preserved (Blech & Rohlfien, 1987). In the key to females presented below are not included: Atrichopogon kagiensis (known from male), A. rufescens Kieffer (nomen dubium) and A. flavidus (doubtful record, type locality - Philippines).
