Heppner, John B. & Bae, Yang-Seop, 2024, Three new species of Cirrothaumatia Razowski & Becker from Peru, with notes on the genus (Lepidoptera: Tortricidae: Tortricinae: Cochylini), Zootaxa 5418 (3), pp. 268-278 : 272-273

Cirrothaumatia huemboana Heppner & Bae , new species

( Figs. 2 , 5 , 11 , 18 )

Type-locality: Huembo Reserve, La Florida, Amazonas, Peru.

Diagnosis. This species can be distinguished by the much smaller accessory bursa of the female genitalia ( Fig. 5 ) (i.e., one-third the size of that of C. pichita n. sp. and C. vesta ), and the stentor-like ostial funnel, similar to that of C. pichita n. sp.

Description. Wing expanse: 13.7 mm female (n = 1). Female ( Fig. 2 ). As in C. pichita n. sp. but with the following particulars: Head ( Fig. 2a–b ): caudo-lateral scale tufts white, to slightly brown-gray caudally; labial palpus white, with many tan to brown-gray scales laterally on segment two and more so on basal segment; antenna scape tan. Thorax: Dark brown mottled with white anteriorly, with many scales dark orange-tipped (especially on metathorax), and some maroon scales mixed in. Forewing ( Fig. 2 ) darker than in C. pichita n. sp. with much smaller areas of white scaling, and subterminal fascia with median knob-like extension very short. Hindwing ( Fig. 2 ) brown and less translucent than in C. pichita n. sp.

Abdomen. Female genitalia ( Fig. 5 ) as in C. pichita n. sp., but sterigma band slightly broader and without small ventral triangular caudal extension; ostial funnel ( Fig. 5a ) straight and uniformly broad, short stentor-like, but ductus bursae with more ridges along its length; accessory bursa very small and from short duct. Male. Unknown.

Type materials. Holotype. Female , Huembo Reserve (2085 m), nr. La Florida, Dept. Amazonas, Peru, 18‒20 Oct 2012, J. B. Heppner & C. Carrera (gen. slide JBH-4469; adult photo 15857) (deposited at MGCL, on indefinite loan from UNALM).

Etymology. The species is named after the Huembo Reserve, near the small town of La Florida (ca. 7km distant on the main road eastwards), Dept. Amazonas, Peru.

Biology. Unknown. Habitat submontane Andean forest ( Fig. 11 ).

Distribution. Known only from the eastern Andean submontane site at Huembo Reserve (2085 m) ( Fig. 11 ), a mountain upland area above a deep canyon, near the town of La Florida, Dept. Amazonas, in northern Peru ( Fig. 18 ).

Discussion. Cirrothaumatia pichita n. sp. and C. huemboana n. sp. are clearly sister-species, but they can be separated by maculation and genital features. Discovery of the males of the two may provide further distinctions. The seemingly slight maculation differences between these two species can be interpreted as significant when compared to C. moyobamba n. sp., which also has similar maculation and yet has very different female genitalia.
