Eucorydia xizangensis Woo & Feng, 1988 – Wikispecies link – Pensoft Profile
- Eucorydia xizhangensis Woo & Feng, 1988: 29, fig.1, male holotype.
Type material examined
HOLOTYPE of Eucorydia xizhangensis, male (SWU, IPP0156), CHINA: Tibet: Beibeng Township [背崩乡], Motuo County [墨脱县], Nyingchi City [林芝市], 800–1200m, 10.VI.1983, Yin-Heng Han leg.
Diagnosis
This species resembles E. splendida sp. n. and E. hilaris, but can be easily distinguished by its tegmina marking pattern, the basal metallic portions of E. xizangensis are much reduced, while the latter two have the basal portion of tegmina widely metallic bluish green. E. xizangensis can also be easily distinguished from E. splendida by: 1) hind margin of supra-anal plate straight (Fig. 10A, No. 1-2), while concave in E. splendida (Fig. 10B, No. 1-2); 2) L3 with apex less hooked (Fig. 10A, No. 3), while L3 strong hooked in E. splendida (Fig. 10B, No. 3); 2) R2 with an elongate irregular process on the left, apex of the process curved (Fig. 10A, No. 6), while R2 normally protruded toward left in E. splendida (Fig. 10B, No. 6).
Redescription
Holotype (male): measurements (mm): body length 14.1, overall length 16.5, pronotum length×width 4.5×6.6, tegmen length 12.4. Median size, deep metallic blue with large yellow area (Fig. 9A, B).
Head metallic bluish black, ocelli distinct. Pronotum deep metallic blue, margins with black setae. Mesonotum and metanotum purplish brown. Tegmina orange, Sc field of each tegmen metallic bluish purple, which areas extend and direct inward, forming a large round spot around CuP in cfr; wings yellow entire. Legs shiny black, with black pubescence, spines on the legs black.
Abdomen in ventral view orange, the last four sternites metallic black, styli black, S6 slightly yellowish medially and with two small yellow spots laterally; in dorsal view orange, T5 and T6 with lateral margins narrowly blackish brown, T7 and T8 with median orange, lateral parts black. Supra-anal plate black, hind margin nearly straight, cerci black, long (Fig. 10A, No.1-2); subgenital plate with robust styli.
Genitalia (Fig. 10A): L3 slender, strongly curved, apex thinner; appendage sclerite narrow, base enlarged, round, left portion roundly protruded, distal portion elongate, apex bud-like protruded; R2 with an elongate irregular process on the left, apex of the process curved.
