Lycocerus kubani : Kazantsev and Brancucci 2007 : 251. Type material examined. Holotype : 1♂ (NMPC), China, Shaanxi, Haozhenzi env., 1350-2000m, 14-24.VI.1999, lgt. S. Murzin. Non-type material examined. China: 1♂, 1♀ (IZAS), Hubei, Xingshan, Xiaohekou, 700 m, 11.V.1994, leg. X. K. Yang; 1♀ (IZAS), Hubei, Xingshan, Longmenhe, 1400 m, 16.VI.1993, leg. Z. R. Huang; 1♀ (IZAS), same locality as the preceding, 1310 m, 15.VI.1993, leg. J. Yao. Descriptive notes. Male. Aedeagus: basal piece obviously longer than dorsal plate of each paramere (Fig. 5A-C ); ventral process of each paramere thin and nearly straight, approaching to each other in ventral view (Fig. 5A ) and inclining dorsally in lateral view (Fig. 5C ); dorsal plates of parameres feebly longer than ventral processes (Fig. 5A, C ), with outer margins converging apically in dorsal view, apical margins truncate at apices (Fig. 5B ); laterophyse feebly shorter than ventral process, with apices acute and directing dorso-outwards (Fig. 5C ). Figure 5. Aedeagus A-C Lycocerus kubani ( Svihla , 2004) D-F L. zdeneki ( Svihla , 2004) A, D ventral view B, E dorsal view C, F lateral view. Scale bars: 1.0 mm. Female. Internal organ of reproductive system (Fig. 14C ): spermatheca feebly longer than diverticulum; accessory gland ~ 1.2 x longer than spermatheca. Abdominal sternite VIII (Fig. 16G ): triangular emargination in middle and rounded emarginations on both sides of posterior margin, lateral emarginations obviously deeper and wider than the middle one, the portion between lateral and middle emarginations narrow and acute at apices, obviously extending over apices of latero-apical angles, which are rounded. Distribution. China (Shaanxi, Hubei). Remarks. The aedeagus of this species was illustrated only in ventral and lateral views by Svihla (2004) . Here, the aedeagus is illustrated in ventral, dorsal, and lateral views, and female internal genitalia is illustrated for the first time. Additionally, the distribution range of this species is expanded, with geographic records added from Hubei province.
