Macunahyphes pemonensis Molineri, Grillet, Nieto, Dominguez & Guerrero, 2011

( Figs. 1–6 )

Known stages. I ♂♀ ( Molineri et al. 2011).

New records. Brazil, Amapá (Pedra Branca and Amapá municipalities).

Material examined. PT3 (9I), PT 11 (3I).

Diagnosis. Adapted from Molineri et al. (2011): eyes similar in both sexes, undivided; 2) forewings with welldeveloped CU-A lobe, especially in males ( Fig. 3 ); 3) longitudinal vein CuP absent in both sexes ( Fig. 3 ); 4) hind wings absent in both sexes; 5) membranous filaments of mesoscutellum absent; 6) styliger plate slightly projected posteriorly as a columnar base; 7) forceps 3-segmented, second segment with a basal swelling ( Fig. 5 ); 8) penis heavily sclerotized, wide basally and narrowing distally, with a smooth (without spines) ventral projection ( Figs. 4–6 )

Discussion. The species M. pemonensis was included in Macunahyphes by the presence of a ventral projection on the penis, longitudinal vein CuP absent and styliger plate projected posteriorly as a columnar base ( Molineri et al. 2011). The only important feature missing in its description ( Molineri et al. 2011) was the shape of its forceps, since all of the specimens examined by the above-cited authors had lost this structure. In this study we were able to collect two specimens with forceps, which possess a basal swelling in the second segment. The presence of a basal swelling in the forceps does not corroborate the placement of this species in Macunahyphes ; on the other hand, the presence of a ventral projection on the penis and longitudinal vein CuP absent does corroborate this placement in Macunahyphes . Ascertaining the generic allocation of this species will remain difficult until nymph of this species is described and a comprehensive cladistic study is performed.

Distribution. VENEZUELA: Bolívar ( Molineri et al. 2011).
