Etymology The specific name is derived from the Latin adjective ‘ furcutus ’, referring to the bifurcate apical part of the endosoma.

Pygofer ( Fig. 5F–G ) in ventral view symmetrical; in lateral view, lateral lobes arcuate and extended caudally. Medioventral process lanceolar in ventral view. Anal segment ( Fig. 5F, H ) flat tubular, dorsal margin slightly convex, ventral margin curved, apical margin expanded downward in lateral view; 2.5× as long as wide in dorsal view; anal style strap-shaped, not extending beyond anal segment. Gonostyli ( Fig. 5G, I ) symmetrical ventrally; in inner lateral view, base of ventral margin concave, apical margin rounded. Aedeagus ( Fig. 5J–M ) with four processes. Centre of dorsal margin of periandrium with a short laminal process, base large, apex bifurcated, directed dorsocaudad; ventrally around midlength of periandrium with a slender spinose process, slightly curved, directed caudad. Endosoma large, basal part highly sclerotized, apical part with two processes bearing small teeth: one wide and flat, with its tip directed ventrad, the other directed ventrocephalad.

Distribution China ( Guizhou ). Remarks This species was identified with the help of Pei Zhang, and is similar to Andes bifidus sp. nov. in appearance, but differs in: (1) middle dorsal margin of periandrium with a short laminal process, base large, apex bifurcated (dorsal margin of periandrium with a spinose process in A. bifidus ); (2) ventrally around midlength of periandrium with a slender spinose process, slightly curved ( A. bifidus without a process in this position); (3) apical part of endosoma bifurcated, margin with small teeth (endosoma not bifurcated in A. bifidus ).
