Description
Genus: Macrogynoplax Enderlein
The genus is known from Suriname, Guyana, Venezuela, Peru and Brazil, where it is found at both high and low altitudes. Eleven species are known (Froehlich 2003). One species occurs in southeastern Brazil (M. veneranda Froehlich) and five in the Amazon (M. guyanensis Enderlein, M. delicata, M. poranga, M. pulchra Ribeiro-Ferreira & Froehlich and M. marauia Froehlich).
The species vary in body length from 7.6 to 11.3 mm and are noted by pale yellow coloration. A pair of vitreous ocelli are margined in black, separated by the diameter of two to three ocelli. The medial margin of compound eyes is composed of rows of non-pigmented facets. Filiform antennae are composed of 60–70 segments, with the scape being longer and wider than the filament. Maxillary palpi 5-segmented and labial palpi 3-segmented. Pronotum with little pilosity. Legs covered with short pilosity, except femora, which has longer setae set equidistant on anterior and posterior ventral surfaces. Tibiae long, unpigmented, with ventral anterior and posterior setae. Tarsi with longer setae on last tarsomere. Forewing of male varying in length from 9 to 21 mm and of female from 12 to 23 mm. Ninth male sternum with large median lobe and anteriorly projected, differentiated setae, its posterior margin shaped as semicircle with distinct short setae. The male hammer is subcircular, forming a low callus. Penial armature is partially sclerotized, with the apex generally narrower than the base. Female subgenital plates generally covering more than half of the ninth sternite, with a slightly straight, emarginated or rounded posterior margin, covered with small anteriorly, posteriorly and laterally directed setae.
