Description:
Female: Head width is 2.4 times greater than its length, and wider than the thorax. The frons is not concave medially. On both sides of the frontal ridges, there are transverse veins that are arc-shaped and connected at the top and sides to the base of the mandibles. The posterior ocelli are located close to the edge of the compound eyes; the distance between them is not greater than the diameter of an ocellus. The postocular region is narrow. The compound eyes are oval; at 56x magnification, the eyes have short, sparse hairs.
The antennae have 11 segments and are club-shaped. The first antennal segment is approximately four times longer than the second segment. The second antennal segment is longer than the third. The fourth and fifth antennal segments are equal in length, each shorter than the third segment. The sixth segment is slightly shorter than the fifth and wider than it is long. The antennal club has 5 segments, with the length to width ratios as follows: 3:3; 3.5:4; 4:4; 3.5:4; 5:3.
The thorax is shorter than its width and shorter than the abdomen. The mesoscutum lacks a median furrow, and there is a smooth, shiny triangular piece in front, called the skaphion. The mesoscutum has small granular veins. The forewing is twice as long as it is wide; the postmarginal vein is longer than the stigmal vein.
The abdomen is longer than it is wide. The second tergite is longer and wider than the other abdominal tergites. The first and second tergites have longitudinal veins that form circles in the median abdominal veins.
The body is black. The anterior portion of the first antennal segment is brown; the remaining portion is black or dark brown. Antennal segments 2-6 are dark brown; the antennal club is black. The tips of the femora, the trochanters, the tibiae, and the tarsi are yellow to brown. The coxae are black.
