GRUMICHELLA CRESSAE CALOR & HOLZENTHAL SP. NOV. ( FIG. 9 )

Diagnosis: Grumichella cressae can be diagnosed by the following characters: male forewings with 12 brown spots; male genitalia bearing segment X not flattened, lateral view; 1st article of inferior appendage with well-developed basomesal protuberance; 2nd article of inferior appendage shorter than apicodorsal portion of 1st article; apex of 2nd article acuminated and curved mesad. It is most similar to G. blahniki sp. nov., but differs in having segment X with posterolateral borders developed, and tergum IX bearing 1–2 small protuberances posterodorsally, which are absent in G. blahniki sp. nov.

Adult: Head and body yellowish brown.

Male: Forewing length: 9–10 mm. Forewing light golden brown, with 12 small brown spots. Male genitalia as in Figure 9 . Abdominal segment IX annular; in dorsal view, with anterior margin nearly straight, posterior margin nearly straight; in lateral view, pleural region heavily setose; tergum IX bearing a pair of small probuberances posterodorsally. Preanal appendage setose, at least 4× as long as wide; in lateral view, digitate, apex rounded. Segment X saddle-shaped; in lateral view not flattened, dorsal margin slightly concave, apex
