Type material
HOLOTYPE: CHINA: Guizhou: Male (SWU, ex SHNU), Lijiaba [李家坝], Mayanghe Natural Reserve [麻阳河自然保护区], Yanhe County [沿河县], 700m, 7.VI.2007, Liang Tang leg. PARATYPES: CHINA: Guizhou: 5 males (GZU), Daheba [大河坝], Yanhe County [沿河县], 450–700m, 5–12.VI.2007, Qiong-Zhang Song leg.
Diagnosis
This species resembles Eucorydia guilinensis sp. n., but can be distinguished from the latter by the following characters: 1) body larger (15.9–16.3 mm) and broader (8.6–8.8 mm), while body small (13.8–14.2 mm) and narrow (7.0–7.2 mm) in E. guilinensis; 2) the white pubescence on tegmina is mainly limited to the suture of left tegmen and 1/3 of basal anal area on both tegmina, while the pubescence more widely distributed at the base of tegmina in E. guilinensis; 3) the concave part of supra-anal plate more straight (Fig. 10C, No. 1-2), while more round in E. guilinensis (Fig. 8D, No. 1-2); 4) the appendage sclerite with basal left protruded, distal margin of the protruded part straight (Fig. 10C, No. 5), while the appendage sclerite with basal left protruded and strongely curved toward posterior (Fig. 8D, No. 5).
Description
Male: Measurements (mm): body length 12.7–13.2, overall length 15.9–16.3, pronotum length×width 3.9–4.1×6.8–7.0, tegmen length 12.6–12.8. Median size, broad, generally metallic green with orange band (Fig. 7J–K).
Head metallic greenish black, vertex with black pubescence. Pronotum metallic greenish blue entire, with short white pubescence, margins with black setae. Tegmen short and broad, metallic greenish blue, in resting position, the distal half of tegmina with a transverse orange band, occupying nearly 1/7 of the tegmen length, apical portion of the tegmen metallic bluish brown; surface of the basal edges of the tegmina, the sutural margin of left tegmen, and the orange band covered with short white pubescence. Wing transparent, slightly brownish. Legs dark brown, with blackish pubescence, spines on the legs brown.
Abdomen in ventral view brownish black, lateral margins orange except the last four sternites; in dorsal view, terga purplish black, T3-T5 orange laterally. Supra-anal plate dark brown, hind margin concave, cerci dark brown, short (Fig. 10C, No. 1-2); subgenital plate with robust styli.
Genitalia (Fig. 10C): L3 slender, curved, apex with a distinct hook; the appendage sclerite with basal left protruding, distal margin of the protruded part straight, distal portion with a bud-like process; R2 round, basal left with a shallow protruding, shape as in Fig. 10C, No. 6.
