Type species: Multiformis longlingensis sp. nov.
Etymology. The name of the new genus refers to its aedeagus arounded with some processes.
Description. Body medium-sized, 6.0-7.5 mm long (including tegmen), usually dirty yellow or black with yellow, with a black mark similar to a Chinese character “ ”, and a white marking on anterior margin of vertex. Head ( Figs 1, 3 View FIGURES 1 – 4 ) with crown declivous, in dorsal view nearly two times longer and three times wider than eye; median carina complete but weakly elevated; surface between median and lateral carinae weakly concave, glabrous, without longitudinally striate. Front of head ( Figs 1, 3 View FIGURES 1 – 4 ) slightly conically produced; vertex slightly shorter than wide, about as long as or shorter than pronotum, with symmetrical markings; lateral margin carinate; median longitudinal carina lamellate; submarginal carinae convergent on crown; a round elevated structure medially on crown. Ocelli ( Figs 1, 3 View FIGURES 1 – 4 ) small, submarginal, about in the middle of eye and vertex. Face ( Figs 2, 4 View FIGURES 1 – 4 ) including eyes shorter than wide; frontoclypeus with median longitudinal carina more strongly elevated in upper half than in lower half, laterally obliquely striate; clypellus broad and swollen at base; lora nearly reaching middle of clypellus. Pronotum broad, wider than head, usually gray black. Scutellum ( Figs 1, 3 View FIGURES 1 – 4 ) triangular, shorter than pronotum, with transverse depression distinct. Forewing ( Fig. 10 View FIGURES 5 – 10 ) veins slightly prominent, with R1a present; four apical cells; appendix very narrow.
Male pygofer ( Figs 5 View FIGURES 5 – 10 , 11 View FIGURES 11 – 15 ) without ventral process, with some small setae near apex. Subgenital plate ( Figs 5, 9 View FIGURES 5 – 10 , 11, 15 View FIGURES 11 – 15 ) elongate, ventromedial row of macrosetae regularly distributed, row of elongate fine setae along outer submargin and some long microsetae near apex. Aedeagus ( Figs 6, 7 View FIGURES 5 – 10 , 12, 13 View FIGURES 11 – 15 ) with bilobed, lamellate dorsal apodeme, and paired, tubular, recurved lateral processes and one slender ventral process, respectively; base of aedeagus with pair of triangular, lamellate process recurved ventrally; aedeagal shaft somewhat tubular, recurved dorsally; gonopore apical. Style ( Figs 6–8 View FIGURES 5 – 10 , 12–14 View FIGURES 11 – 15 ) coarse, with foot-like apex of apophysis having elongated lateral angle. Connective ( Figs 6–8 View FIGURES 5 – 10 , 12–13 View FIGURES 11 – 15 ) Y-shaped, stem longer than arms.
Distribution. China (Yunnan) ( Fig. 16 View FIGURE 16 ).
Remarks. The new genus is very similar to Angustella Li externally, but it can be distinguished from the latter by: 1) male pygofer side without ventral process ( Figs 5 View FIGURES 5 – 10 , 11 View FIGURES 11 – 15 ); 2) aedeagus with well developed lateral and ventral processes ( Figs 6, 7 View FIGURES 5 – 10 , 12, 13 View FIGURES 11 – 15 ).
