GRUMICHELLA PARATI
CALOR & HOLZENTHAL
SP. NOV.
(
FIG. 15
)
Diagnosis:
Grumichella parati
can be diagnosed by the following characters: male forewing with 3 brown spots; male genitalia with segment X not flattened, lateral view; 1st article of inferior appendage without basomesal protuberance; 2nd article of inferior appendage longer than apicodorsal portion of 1st article; apex of 2nd article acuminated, curved mesad. It is most similar to
G. jureia
sp. nov.
, but differs in having the 2nd article of the inferior appendage longer than the apicodorsal portion of the 1st article, and segment X with the posterolateral borders developed.
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 15
. Abdominal segment IX annular; in dorsal view, with anterior margin nearly straight, posterior margin broadly rounded; in lateral view, pleural region setose; tergum IX without protuberances dorsally. Preanal appendage setose, at least 4× as long as wide; in lateral view, clavate, apex rounded. Segment X saddle-shaped; in lateral view not flattened, dorsal margin slightly concave, ventral margin abruptly convex, with middle length straight; segment X in dorsal view, subtriangular, with posterolateral borders developed, lateral margins sinuate, narrowing apically, with apicodorsal shelf, shelf slightly trapezoidal, 1/2 as wide as apex of segment X, without sulcus apically. Inferior appendage slightly 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 longer than apicodorsal portion of 1st article, narrow, tapering throughout length, mesal surface not excavate, apex pointed, curved mesally; apicordorsal portion of 1st article digitate, setose. Phallic apparatus simple, phallicata sharply down-curved; with pair of subequal, narrow, posterodorsally directed lateral flanges, apices acuminate; phallotremal sclerites small, U-shaped in dorsal view, with middle region enlarged.

. 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.
