Macunahyphes pemonensis Molineri, Grillet, Nieto, Dominguez & Guerrero, 2011: 45.
Diagnosis According to the original description, the male imago of Macunahyphes pemonensiscan be distinguished from all congeners by the following combination of characteristics: 1) fore wings hyaline, membrane tinged with gray on basal half of C and Sc regions and basally to vein A; 2) styliger plate very slightly projected posteriorly as a columnar base for each forceps, with a pair of sublateral acute projections on the hind margin; 3) penis long and slender, with apical furrow and a somewhat protruding ventral projection.
Material examined BRAZIL: 2 ♁♁, imagines, Amapá, Pedra Branca, stream crossing highway BR 210 near Pedra Branca(PT3), 00°37′38.9″ N, 51°38′15.2″ W, 3 Aug. 2011, P.V. Cruz, A. Pesand A.S. Fernandesleg. ( DZRJ3156).
Remarks In the original description of the male imago of M. pemonensisthere is no mention of the presence of a dark purple spermatic duct that is laterally visible from outside, a character also found in M. araca sp. nov.and evident from the fresh material of M. pemonensisstudied here (see Belmont et al.2015: figs 2, 6). In addition, a new interpretation is given to the ventral structure present in the penis described by Molineri et al.(2011). The lateral margins of the penis lobe are strongly sclerotized and are ventrally twisted, forming a lateral narrow Fap on each side of the penis. The area between these Faps, interpreted as a ventral structure in the original description, is in fact a shallow groove (see Belmont et al.2015: figs 4–6).
