description: Agripialus itatiaia sp. n.   
(Figs 5–6, 22, 26, 33, 43, 47, 53)  
 Type material. Holotype ♂ (Figs 5a–b): 4,- XII, [19]26/ No. 24, J. F. Zikán/ Coleção J. F. Zikan/ Z. 4713/ HOLOTYPUS, Agripialus itatiaia C. Mielke, Grehan & Koike, 2021 / (CEIOC).   
 Paratype (1♀). BRAZIL. São Paulo: Queluz, Serra Fina, 2400 m. 7.XI.1986 (CGCM 25.532 (CGCM)).   
 Diagnosis. Easily distinguished from congeneric species by a longer antero-posterior trapezoidal sternite VII (as long as sternite VI) in the female (Fig. 33), in contrast to the proportionately wider rectangle of the other two species, and by the length of the ductus bursae being four times longer than the corpus bursae (Fig. 53). The male differs from that of Agripialus caparao sp. n.] by absence of a whitish submarginal line on the forewing (Fig. 5a) and the presence of a minute sclerotised square on the posterior portion of the pseudotegumen (Fig. 47).   
 Description. Male (Figs 5, 22, 43, 47).   
 Head. Antenna with ~37 antennomeres. Basal and second labial palpomeres each respectively three and five times longer than distal palpomere.   
 Thorax. Forewing length: 15 mm, wingspan: 31 mm. Wing ornamentation as shown in Fig. 5.   
 Genitalia (Fig. 47). Tegumen L-shaped. Saccus broadly U-shaped, posterior margin slightly notched. Pseudotegumen weakly sclerotised with a small rectangular sclerotisation posteriorly; anteriorly rectangular as a transverse bar, fused mesally and internally projected to articulate with fultura inferior. Fultura inferior posteriorly concave, projecting, and tapered anteriorly with concave lateral margins. Valva setose, distal half strongly sclerotised as long as basal portion.   
 Female (Figs 6, 26, 33, 53).   
 Head. Antenna with 32 antennomeres. Basal and second labial palpomere respectively two and three times longer than distal palpomere.   
 Thorax. Forewing length: 20 mm, wingspan: 40 mm. Wing ornamentation as shown in Fig 6.   
 Genitalia (Fig. 53). Connection between dorsal plates slightly sclerotized, dorsal plate subrectangular with broad, rounded ventral medial corner (anal papilla), and narrow knob-like antero-lateral corner; subanal plate slightly sclerotised, subrectangular. Lamella antevaginalis slightly sclerotized. Ductus bursae four times longer than corpus bursae.   
 Geographical distribution. Only known from a single site in Itatiaia National Park at 2400 m (Figs 58, 61).   
 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.
