description: Mutipialus monticolus sp. n.   
(Figs 13–15, 17, 35, 39, 42, 46, 50, 55, 57)  
 Type material. Holotype ♀ (Figs 13a–b): BRAZIL – São Paulo (SP), Campos do Jordão, Lavrinhas, 1898 m, 2.I.1999 (30), R. Koike leg., W 45°25’39’’ S 22° 43’10’’ / 43.527 Col. C. Mielke / HOLOTYPUS, Mutipialus monticolus C. Mielke, Grehan & Koike, 2021 / (DZUP).   
 Paratypes (1 ♂, 1 ♀). BRAZIL. Same locality and collector as the holotype: 1♀, 23–24.I.1998 (CGCM 35.737 (CGCM)); 1 ♂, 27–28.XII.1997 (CGCM 29.697 (CGCM)).   
 Diagnosis. Readily distinguished from congeneric species by i) ♂ forewing ground colour dark brown with a light brown stripe on the CuA dorsally (Fig. 14a), (ii) ♂ sternite VII bilobed posteriorly (Fig. 46), iii) posterior margin of the ventral wall of the saccus mesally projected posteriorly (Fig. 50b), iv) tergal lobe and pseudotegumen less projected posteriorly, v) ventro-posterior projection of the pseudotegumen tapered, not digitiform, vi) fultura superior not as deeply concave, vii) valva curved and subrectangular, and viii) the longer ductus bursae and corpus bursae (one and a half times to that of M. dilatus sp. n.) (Fig. 57).   
 Description. Male (Figs 14, 39, 42, 46, 50).   
 Head. Antenna with 32 antennomeres. Mesal and distal labial palpomere twice as long as basal palpomere.   
 Thorax. Forewing length: 13 mm, wingspan: 27 mm. Wing ornamentation as shown in Figs 14.   
 Genitalia (Fig. 50). Tegumen oblique, rectangular, slightly curved, and strongly differentiated, by sclerotisation, from pseudotegumen. Saccus U-shaped, posterior arms slightly projected ventrally, ventro-posterior margin projected as a shelf. Tergal lobes and pseudotegumen forming a robust and irregular shaped structure; dorso-posteriorly each side extending posteriorly and connected mesally by robust membrane, both sides ventrally projected, with expanded posterior edges and bifid anteriorly; a finely fused ridge emerges from the digitiform antero-dorsal projection and expands posteriorly as a shelf on each side. Fultura inferior trapezoidal. Fultura superior subsquare, slightly concave (in ventral view). Valva subrectangular, curved with slightly lobate costa.   
 Female (Figs 13, 15, 17, 35, 55, 57).   
 Head. Antenna with 34 antennomeres. Mesal and distal labial palpomere respectively three and two times the length of the basal palpomere (Fig. 17).   
 Thorax. Forewing length: 18–20 mm, wingspan: 39–42 mm. Wing ornamentation as shown in Fig 13, 15.   
 Genitalia (Figs 55, 57). Dorsal plates rectangular narrowing dorsally, fused dorsally to form narrow arc in posterior view. Lamella antevaginalis U-shaped, dorso-ventrally narrow, mesally setose and slightly projected medially (arrowed in Fig. 55a). Subanal sclerites lightly sclerotised, subrectangular, oblique. Corpus bursae two and a half times longer than ductus bursae and wider at junction with ductus bursae.   
 Geographical distribution. Only known from the type locality at higher elevations (1900 m) in the Mantiqueira Mountains of eastern São Paulo state (Figs 58, 60).   
 Host plants. Unknown.   
 Etymology. The proposed specific name alludes to the high altitude where this species occurs. It is treated as an adjective in the nominative singular.
