Stegana (Steganina) hirtifoliacea sp. nov.

(Figs 2G, 10)

Diagnosis. This species resembles S. unguiculata sp. nov. in the colour patterns of body (Fig. 2G) and male terminalia (Fig. 10), but can be distinguished by the aedeagus with 4 short and thick processes per side (Fig. 10C); sublateral processes of gonopods shorter and broadly separated than in S. unguiculata sp. nov. (Fig. 10D). The minimum interspecific genetic distance to S. unguiculata is 3.3%, which is smaller than to other species (Table 2); see description of S. unguiculata for more detail.

Description. Male: Pedicel yellow medially, black laterally; first flagellomere nearly black. Palpus yellow basally, brown on distal 1/ 3 in male. Mesonotum brown (Fig. 2G). Katepisternum dark brown on upper part, whiteyellow on lower part (Fig. 2G). Scutellum black (Fig. 2G). Legs dark brown to black, yellow on basal part of fore femora and 2nd to 5th tarsomeres. Fore femur with 3 long setae on distal half of posteroventral surface. All abdominal tergites brown (Fig. 2G); all sternites yellowish brown. Male terminalia (Fig. 10): Epandrium with ca. 20 setae near posterior portion per side. Surstylus broad in lateral view. Cercus lacking pubescence. Tenth sternite with 1 pair of asymmetric projections sublaterally. Paramere with ca. 2 sensilla. Aedeagus with pubescence. Gonopods with 1 suberect lobe-like process bearing several pubescence.

Etymology. A combination of the Latin words: hirtus + foliaceus, referring to the aedeagus with several setae.

Distribution. China (Yunnan).
