A compact CPW-fed monopole antenna composed of an elliptical monopole and a coplanar
trapeziform ground plane has been proposed in [35].
Tergite 1 of metasoma smooth, 3.5x as long as broad posteriorly, with small, isolated glymma and short, shallow groove before glymma, with petiole round or slightly
trapeziform in cross-section.
is easily separated from the other species of the genus as following characters: mid and hind legs with 2 pseudospurs on ta1, ta2 and ta3; length of ta4 shorter than ta5 in all legs; inferior volsella
trapeziform.

3D):
Trapeziform, with supragenital bridge, not turned relatively to other segments, apex of ventral wall placed almost medially.
MOA
trapeziform, longer than wide or as long as wide.
18 mm long, free; anthers 2.5-3 mm long, green, base obtuse, apex obtuse and minutely apiculate, compressed laterally, dorsifixed at 1/3 of their length above the base; pollen sulcate, subellipsoid to
trapeziform, exine microreticulate with irregularly polygonal lumina, muri thickened; stigma simple-erect, ca.
The stainless-steel exterior housing is a
trapeziform design, which allows placement of multiple feeders around a central point of discharge to save floor space.
