Gladkara bifida sp. nov.

( Figs 4 A–I, 12M–P)

Type locality. China, Yunnan province, Mengyuan, Sanchahe nature reserve.

Type material. HOLOTYPE: ♁, CHINA: YUNNAN: Mengyuan, Sanchahe , 940 m, 20.xii.1999, I. Dworakowska leg. ( NWAU) . PARATYPE: CHINA: YUNNAN: 1 ♀, Menglun, 570 m, 7.xii.1999, I. Dworakowska leg. ( NWAU).

Description. Body slim, beige ( Figs 12 M–P), forewing with black patch at tip of third apical cell.

Abdominal apodemes 2S ( Fig. 4A ) extended to hind margin of sternite III.

Male terminalia. Anal tube appendage ( Figs 4B, C ) with basal part relatively long, apical part knife-like, apex pointed and slightly curved ventrad. Pygofer side ( Fig. 4B ) rectangular, with oblique row of macrosetae from lower basal angle to dorso-caudal angle, variable in size, without long fine setae; dorsal appendage ( Figs 4B, C ) bifurcated, dorsal branch short, ventral branch much longer, directed ventrad basally then bent caudad at right-angle. Subgenital plate ( Fig. 4E ) relatively broad apically, with irregular row of 6–7 macrosetae, outer margin with row of stout setae subapically similar to those in type species. Style ( Fig. 4F ) curved ventrad apically, apex pigmented, without sculpture. Connective ( Fig. 4G ) with distinct central lobe. Aedeagus ( Figs 4H, I ) with pair of short processes on atrium and pair of long, straight preatrial processes; dorsal apodeme wider than preatrium in caudal view; gonopore terminal. Measurements. Male body length 3.75 mm; female body length 3.70 mm.

Diagnosis. Resembling the type species, G. albida , in having the apex of the style undecorated and the connective with a central lobe, and in the shape of the aedeagus, but with a much longer ventral branch of the pygofer dorsal appendage and two pairs of basal aedeagal processes.

Etymology. The specific epithet is derived from the Latin adjective “ bifidus ” which means “forked”, referring to the forked dorsal appendage of the pygofer.
