11. Eridachtha atrihispida Park , sp. nov.

LSID: urn:lsid:zoobank.org:act:53C31F72-5AC7-4BAD-9134-8A80BE262D16 ( Fig. 19 )

Type specimen. Holotype female, Uganda, Mpigi, Mpanga For., 0˚12'24"N 32˚18'05"E, 1–5 v 2019, leg. K.T. Park, J.M. Koo, J.D. Kim, gen. slide no. CIS-7610, in NIBR.

Diagnosis. The new species is similar to the preceding new species by having a similar forewing and hind tibia equipped with a scale tuft as noted in the previous diagnosis. The new species E. atrihispida can be distinguished from the similar congeneric species by the different shape of antrum, as described below, in the female genitalia.

Description. Female ( Figs 19A–D ). Wingspan 15.0 mm.

Head: head, antenna, and labial palpus pale orange. Second segment of labial palpus strongly arched, thickened, and devoid of rough scales dorsally; 3 rd segment slender as long as 2 nd segment, and strongly upturned.

Thorax: tegula and thorax pale orange dorsally. Hind tibia with brownish rough scales and with blackish scale-tufts apically, near middle and apex ( Fig. 19D ). Forewing ground colour pale orange; costa slightly arched around basal 1/3 and also beyond 3/4; apex produced; termen oblique. Hindwing ground colour yellowish-white as broad as forewing.

Abdomen: no spinous zones dorsally.

Female genitalia ( Fig. 19E ): apophyses anteriores slightly shorter than apophyses posteriores, dilated apically. Sternite VIII deeply concave on anterior margin. Antrum cup-shaped, not well demarcated from ductus bursae. Ductus bursae long, about 3 times the length of the antrum, weakly sclerotized in distal half. Corpus bursae small, about 1/3 the length of corpus bursae; signum absent.

Male unknown.

Distribution. Uganda (Mpigi).

Etymology. The species name is derived from the Latin, - atra (= black) and–- hispidus (= bristly), referring to the blackish clustering of hairs on the tibia of the hind legs.
