Diagnosis.

This species resembles the tonkinensis population of E. dasytoides , but differs from the latter by: 1) having whitish pubescence at the base of tegmina, 2) the cerci of male is shorter; 3) median of supra-anal plate widely “V” shaped (Fig. 8C, No.1-2) (the concave part narrow, more round laterally in the supra-anal plate of tonkinensis population of E. dasytoides ); 4) R2 elongate and rhomboid (Fig. 8C, No. 6) (nearly round in the tonkinensis population of E. dasytoides (Fig. 6F, G–O, No. 2).

Description.

Male: measurements (mm): body length 13.8-15.1, overall length 18.9-21.5, pronotum length×width 4.5 –4.8×6.8– 7.4, tegmen length 14.1-15.9. Median size, metallic purplish blue (Fig. 7 F–G).

Head shiny, metallic blackish blue; antennae (except the whitish segments), maxillary palpi and labial palpi black. Pronotum metallic blue, with black long setae. Tegmina with basal half metallic blue, the basal half of anal areas with white pubescence, distal half with a yellow band transversely across the tegmina which occupies nearly 1/6 of the tegmen length, the basal edge of the band metallic purple, the apical portion of tegmina blackish, slightly metallic purple. Wing brown, venation brown, distinct, median of the outer margin with elongate yellow spots, a yellow trail originates from each spot and extends to the median of the wing. Legs black, slightly pubescent, spines on the legs black, with apex reddish brown.

Abdomen in ventral view, margins pubescent, the last two and the lateral portions of 6th to 7th sternites black, slightly metallic, the rest orange. Supra-anal plate with hind median broadly concave, cerci short (Fig. 8C, No. 1-2); subgenital plate with two long and robust styli.

Genitalia (Fig. 8C): L3 with the apex hook gently curved; the appendage sclerite with basal left roundly protruding, hind portion elongate, gradually narrower; R2 elongate, slightly rhomboid shaped, details as in Fig. 8C, No. 6.

Female unknown.

Etymology.

The species epithet " pilosa " refers to its whitish pubescence on tegmina base.

Remarks.

This species and E. dasytoides were confused and misidentified in Woo et al. (1986). They treated this species as E. dasytoides , and an E. dasytoides individual from Yunnan as a new species E. paucipilosa Woo, Guo & Feng.

Natural history.

The holotype was found inside a mixture of humus by the second author.

Distribution.

China: Yunnan.
