Macunahyphes araca
status

 

Macunahyphes araca sp. nov. and M. pemonensis are the darker species of the genus. Macunahyphes araca sp. nov. can also be distinguished from all other species by the unique spermatic duct, which is visible laterally from outside due to its dark purple coloration, a characteristic also found in M. pemonensis (see Belmont et al. 2015: figs 1, 6). As in M. pemonensis , the styliger plate is slightly projected posteriorly as a columnar base for each forceps, with a sublateral acute projection on the hind margin, unlike the one found in M. incognitus . On the other hand, in the new species the penis base is subquadrate, narrowing abruptly in the median zone, as found in M. incognitus . Despite the very similar genitalia of M. araca sp. nov. and M. incognitus , the ventral structure of the new species reaches the deep apical furrow, while the ventral structure of M. incognitus ends before the apical furrow and the penis lobes are almost completely fused. According to the original description, M. incognitus seems to be similar to M. australis regarding the overall coloration, lighter in comparison to M. araca sp. nov.
