Agripialus caparao sp. n.

( Figs 7 , 23 , 25 , 40, 44 , 48 )

Type material. Holotype ♀ ( Figs 7a–b ): Brazil – Minas Gerais ( MG), Espera Feliz, nr. Pedra Menina ( ES), Casa Queimada , 2.200 m, 19.XI.2017, 20°27’28.57’’S, 41°48’31.46’’W, R. Koike & E. Pereira leg./ 35.884 Col. C. Mielke / HOLOTYPUS, Agripialus caparao C. Mielke, Grehan & Koike det. 2021/ ( DZUP) .

Paratype (1♂). BRAZIL. Same locality as holotype, 12.XI.2012, Lepidoptera Lab. expedition ( MZSP) .

Diagnosis. Distinguished in the male from its most similar species A. itatiaia sp. n. by the pseudotegumen lacking sclerotisation posteriorly and by the thinner transverse portion anteriorly ( Fig. 48 ). The whitish submarginal line on the forewing ( Fig. 7a ) is also absent in the A. itatiaia ( Fig. 5a ).

Description. Male ( Figs 7 , 23 , 25 , 40, 44 , 48 ).

Head. Antenna with 37 antennomeres. Basal and second labial palpomere respectively two and four times longer than distal palpomere.

Thorax. Forewing length: 12 mm, wingspan: 26 mm. Wing ornamentation as shown in Fig 7 .

Genitalia ( Fig. 48 ). Tegumen L-shaped. Saccus U-shaped, antero-posteriorly short, posterior margin slightly notched. Pseudotegumen narrow, anteriorly rectangular, almost transverse, fused mesally, and interiorly projected to articulate with fultura inferior. Fultura inferior subtriangular. Valva setose, distal portion strongly sclerotised as long as basal portion.

Female. Unknown.

Geographical distribution. Known from the type locality only at 2200 m ( Figs 58 , 59 ).

Host plants. Unknown.

Etymology. The proposed specific name is homonymous to the national park’s name. It is treated as a noun in the nominative singular in apposition.
