GRUMICHELLA PAPROCKII   CALOR & HOLZENTHAL SP. NOV. ( FIG. 14)

Diagnosis: Grumichella paprockii   can be diagnosed by the following characters: male forewing with 3 brown spots; male genitalia bearing segment X not flattened, lateral view; 1st article of inferior appendage without basomesal protuberance; 2nd article of inferior appendage shorter than the apicodorsal portion of 1st article; apex of 2nd article acuminated, curved mesad. This new species is most similar to G. muelleri   , but differs in having segment X with the posterolateral borders developed, and the apicodorsal shelf on segment X about 1/3 to 1/2 as wide as the apex of segment X.

Adult: Head and body yellowish brown.

Male: Forewing length: 8–9 mm. Forewing light golden brown, with 3 small brown spots, without dark setae on posterodorsal margin. Male genitalia as in Figure 14. Abdominal segment IX annular; in dorsal view, with anterior margin slightly concave, posterior margin broadly rounded, with medial protuberance; in lateral view, pleural region sparsely setose; tergum IX bearing 1 small probuberance posterodorsally. Preanal appendage setose, at least 4× as long as wide; in lateral view, digitate, apex subacute. Segment X saddle-shaped; in lateral view not flattened, dorsal margin slightly concave, apex upcurved, ventral margin slightly convex; segment X in dorsal view, rectangular, with posterolateral borders well developed, lateral margins subparallel, with apicodorsal shelf, shelf almost rectangular, but sometimes varying to rounded, 1/3 as wide as apex of segment X, with ventral sulcus apically. Inferior appendage concave in ventral view, with basal region tuboid, not enlarged; slightly rounded basally, setose, not bearing a basomesal protuberance; middle region of inferior appendage without constriction before apicodorsal region; 2nd article shorter than apicodorsal portion of 1st article, broad basally, tapering throughout length, apex pointed, curved mesally; apicordorsal portion of 1st article digitate, setose. Phallic apparatus simple, phallicata sharply down-curved; with pair of subequal, wide, posteromesally directed lateral flanges, apices not acuminate; phallotremal sclerites small, U-shaped in dorsal view.

Female: Head and body yellowish. Forewing length: 6–7 mm. Forewing yellowish to brown, without dark setae on posterodorsal region. Genitalia inseparable from congeners. Abdominal segment IX lightly sclerotized, with dorsal plate, bearing pair of setose protuberances above appendages of segment X, appendages of segment X small; valves flat, thin, lightly sclerotized, with very short setae.

Etymology: Named in honour of Dr Henrique Paprocki, collector of this species and a colleague who encouraged this revision.

Distribution: Brazil.
