Diagnosis

The salient features of the new species include the following: dorsal margin of periandrium with a laminal process near base, covering the left half of periandrium ( Fig. 2K ); apical left side of periandrium with a laminal process, upper part around the periandrium, bottom part bending cephalad ( Fig. 2K ); basal right side of periandrium with a long circinate spinose process ( Fig. 2J‒M ).

Etymology

The specific name is derived from the Latin adjective ‛ circinatus ’, referring to the one long circinate spinose process arising from the basal right side of periandrium.

Description

MEASUREMENTS. Body length: male 5.87‒6.12 mm (N = 3).

COLORATION. General color yellowish white ( Fig. 2A–B ). Eyes black brown, margin light green; ocelli faint red, semi-translucent. Lateral carinae of frons yellowish white; lateral side of head with a triangular yellowish green spot anterior to the eyes. Antenna faint yellow, base light green. Vertex yellowish brown. Face and rostrum generally yellowish brown. Pronotum yellowish green. Mesonotum yellowish brown. Forewing semi-translucent, basal and middle part of wing with yellow stripes, costal vein with a V-shaped spot, apical half of wing with several irregular dark spots. Stigma yellowish green. Veins and tubercles yellowish brown. Hind tibiae light yellow. Abdomen yellowish brown ventrally.

HEAD AND THORAX. Vertex ( Fig. 2A, C ) 2.8 times as long as wide; anterior margin nearly straightly, posterior margin U-shaped recessed, lateral carina developed, median carina absent. Frons ( Fig. 2D ) 4.0 times as long as wide, lateral carina developed, base of median carina raised, median carina of postclypeus transparent. Pronotum ( Fig. 2A, C ) slightly shorter than vertex; posterior margin recessed. Mesonotum as long as pronotum and vertex combined. Forewing ( Fig. 2B, E ) 2.3 times as long as wide, with twelve apical cells and seven subapical cells; RP 3 branches, MP with 5 terminals: MP 11, MP 12, MP 2, MP 3, and MP 4, fork MP 1 +MP 2 basad of fork MP 3 +MP 4. Hind tibia ( Fig. 6A ) with five lateral spines; chaetotaxy of hind tarsi: 7–9/8, 2 nd hind tarsus with 3 platellae.

MALE GENITALIA. Pygofer ( Fig. 2F–G ) in ventral view symmetrical; in lateral view, lateral lobes arcuate and extended caudally. Medioventral process lanceolar in ventral view. Anal segment ( Fig. 2F, H ) flat tubular, dorsal margin almost straight, ventral margin curved slightly in lateral view; 1.7 times as long as wide in dorsal view; anal style strap-shaped, not extending beyond anal segment. Gonostyli ( Fig. 2G, I ) symmetrical ventrally, inner margin slightly protruding near base, apical margin enlarged; in inner lateral view, dorsal margin recessed, right side of apex with a small process. Aedeagus ( Fig. 2J–M ) with a spinose process. Dorsal margin of periandrium with a laminal process near base, covering the left half of periandrium; apical left side of periandrium with a laminal process, upper part wrapping around the periandrium, bottom part bending cephalad; basal right side of periandrium with a long circinate spinose process, curved dorso-cephalad then strongly bending, directed caudad, and then bending upwards, directed dorso cephalad; apex of ventral margin of periandrium with a laminal process, basal half of periandrium with a laminal process, apex bending to the left. Endosoma slightly sclerotized, without process.

Distribution

China (Yunnan).

Remarks

This species can be distinguished from the other species of the genus by the body color, forewing markings and male genitalia.
