( Figs. 16–26 )

Platytibia ferruginea Ding, 2006: 333 –334, fig. 175A–E.

Male genitalia. Male pygofer subtriangular in lateral view, ventral side sinuate, apparently wider than dorsal, laterodorsal angle not produced, laterocaudal margin broadly expanded caudad in upper half followed by a plate-like process strongly produced at caudoventral angle ( Figs 17, 19 ); in caudal aspect pygofer with a platelike process at each side of lateroventral margin ( Figs 16, 18 ). Parameres rather broad, surpassing ventral side of anal segment ( Fig. 16 ), contiguous in basal half, apices rounded and converging, laterally basad of apex expanded laterad, apices converging ( Fig. 25 ). Aedeagus slender, slightly compressed laterally, broad at base, shortly distad of base slightly bent dorsad, apex strongly narrowing, subapex with flag-like flagellum reflected laterobasad, distally curved to right side, with basal spinose process curved to left, phallotreme subapical on dorsal side at base of flagellum ( Figs 20, 22, 23 ). Genital diaphragm narrow, dorsal margin concave and membranous, medially sclerotized, pigmented, in lateral view with caudally directed process surpassing laterocaudal margin of pygofer ( Figs 18, 19 ). Suspensorium long, articulated with aedeagus ( Fig. 20 ), apparently compressed ventrocaudally, arms short and widely separated, stem nearly 3.0 times as long as arms, basal part narrowed ( Fig. 21 ). Opening for parameres small, ventral margin evenly arched, lateral and anterior margins nearly straight ( Fig. 18 ). Anal segment with two blunt, widely spaced processes ( Fig. 24 ).

Material examined. 1 male (macropterous), China: Hainan Province, Bawangling, 28.V.1983, coll. Yalin Zhang ( NWAFU).

Remarks. The original description of the genus, especially in the characters of the male genitalia, was rather deficient, the illustrations of the type species not exhibiting these particular configurations of the internal genitalia.

Distribution. Known only from the type locality in southern China (Hainan Province).
