Tinodes shunhuangshanensis

description: Tinodes shunhuangshanensis Peng & Sun, n. sp.
(Figs 3a–3d)
Description: Length of each forewing 3.4–3.5 mm (n = 2). Specimens in alcohol with compound eyes black, legs and thorax dark brown, abdomen brown dorsally, pale yellow ventrally, wings light brown.
Male genitalia: Sternum IX concave posteriorly in ventral view (Fig. 3a), nearly boomerang-shaped in lateral view (Fig. 3c). Tergum IX originating from about halfway along posterior margin of sternum IX, narrowly stalked in lateral view (Fig. 3c), nearly triangular in dorsal view (Fig. 3b). Segment X closely fused with tergum IX, completely covered by tergum IX and invisible in dorsal view (Fig. 3b), nearly trapezoidal in lateral view (Fig. 3c). Superior appendages issuing from about halfway along posterior margin of sternum IX, underneath insertion of tergum IX, slightly S-shaped, extended posterodorsad in lateral view (Fig. 3c), club-shaped in dorsal view (Fig. 3b). Phallic sheath process coming from top of sternum IX, with inner branch and paired lateral branches in dorsal view (Fig. 3b); lateral ones short, about half length of phallus, each with two spurs subapically; inner one long, with distal end deeply incised and divided into two lobes; in lateral view (Fig. 3c) inner branch slightly curved downwards and gradually broadened from base to apex, each lobe with two long spurs. Phallus tubular, slender, extended beyond apex of inner branch of phallic sheath process (Fig. 3c). Phallic guide terminal half extended between apical branches of coxopodite in lateral view (Fig. 3c), somewhat heart-shaped in ventral view (Fig. 3d) with small and hardened ventral branches. Coxopodites with basal halves fused mesally in ventral view (Fig. 3a), each with basal half nearly trapezoid in lateral view (Fig. 3c); dorsal branch of each coxopodite in lateral view horn-like, slightly darkened, smooth and hairless, basal 2/3 nearly vertical, and distal 1/3 curved horizontally, in ventral view wormlike; ventral branch slender, curved upward, setose distally in lateral view, rectangular in ventral view. Harpagones each capitate in lateral view; in ventral view bracket-shaped (Fig. 3a); densely setose (Fig. 3a, 3c).
Diagnosis: This species is similar to Tinodes sartael Malicky 2017 from China (He-nan; Hu-bei), both in the boomerang shape of sternum IX in lateral view and in the inferior appendages with apically enlarged harpagones. However, the new species can be easily distinguished by the unique phallic sheath process, which is split into a pair of lateral branches and an apically-incised inner branch.
