Antrops guaramacalensis


Antrops guaramacalensis View in CoL group

This species group consists of eleven apterous species, which occur in the Andes from Bolivia to Venezuela. Seven are known from only 1 or 2 specimens of a single sex; those known from only females are diagnosed but not formally described here. Possible synapomorphies of the clade include an enlarged metapleuron with the posterior spiracle approximately twice as far from the hind coxa as from the posterior margin of the scutum, a reduction or loss of the outer vertical bristles, and loss of the intra-alar bristles. There also appears to be a tendency to have more than 12 pseudotrachea on the labellum, but only a few specimens have the labellum inflated so that these can be counted (numbers of pseudotrachea are combined from the two labellar palps as they are sometimes asymmetrical). However, wing loss is often associated with a suite of correlated morphological changes, and so these characters may represent convergence associated with wing loss rather than synapomorphies. Some specimens of an undescribed species of Boreantrops approach the states seen in this group, although synapomorphies of the male genitalia in that species clearly place it within Boreantrops .
