Typhlocyba triannulata View in CoL sp. nov.

Figs 23–31 View FIGURES 23 – 31 .

Description. Color pattern of dorsum as in Fig.23 View FIGURES 23 – 31 . Patches on vertex orange or light orange, on pronotum and scutellum orange. Forewing with distal part of lognitudinal veins and transverse and apical veins yellowish, with basal patches yellowish ocher or yellowish orange; patches on both ends of brochosome field brown, apical part infuscate; subgenital plate and end of anal tube, ivory, remainder of abdomen including pygofer capsule, dark brown.

Abdominal apodemes reaching to base of 5th abdominal sternite.

Male genitalia: Pygofer side narrowing caudally ( Fig. 25 View FIGURES 23 – 31 ), with well developed broad finger-like protrusion at upper angle of posterior margin, with 2–3 teeth at caudoventral margin, margin between protrusion and teeth with some rigid microsetae ( Fig. 26 View FIGURES 23 – 31 ). Subgenital plate slender with 2 groups of rigid microsetae at inner and outer apical margin, apex hook-like ( Fig. 28 View FIGURES 23 – 31 ). Paramere pigmented with distal part slender ( Fig. 29 View FIGURES 23 – 31 ). Connective well developed, stem slender, nearly twice length of arms ( Fig.27 View FIGURES 23 – 31 ). Aedeagal shaft relatively short with pair of bifurcate, distally directed, subapical processes ( Figs 30–31 View FIGURES 23 – 31 ).

Measurement: male, 3.63 mm (including wings).

Type material. Holotype: ɗ, CHINA. Sichuan Province: Mianning, Alt. 1650 m, 8.xi.1999, coll. I. Dworakowska; paratype, 1ɗ, Sichuan Province: Batang, Zhubalong, Alt. 2450 m, 10.vii.2001, coll. Qiang Sun, light trap (both NWAFU).

Notes. The new species belongs to T. arborea group and is similar to T. equata Dworakowska (1982) in color pattern, but can be distinguished from the latter by 1) pygofer side with long protrusion at upper angle of posterior margin; 2) subgenital plate with apex hook-like; 3) connective nearly Y-shaped; 4) aedeagal subapical processes bifurcate; while in T. equata pygofer side with protrusion not obvious; subgenital plate with apex finger-like; connective nearly M-shaped; aedeagal processes not furcated.

Etymology. The specific name is a combination of the Latin prefix tri- meaning three and the Latin word annulus, meaning ring, referring to the three ring-like marks on the forewings.
