description |
A brown to light brown species, with distinct median vitta and ivory to cream markings. The frons is dark with carinae stramineous to cream in color, distinct and contrasting with the rest of the frons. The antennae are light cream colored to yellow, with segment I dark brown in some specimens. The pronotum is white to cream-colored, with fuscate markings posterior to the eyes and between the median and lateral carinae; the mesonotum is brown with median white vitta. The hyaline wings have a dark mark at the apex of the clavus. The legs are white to light brown, with the apex of the tarsi brown. The abdomen is brown, with a fine white line on the caudal edge of each segment; the lateral projections of the sternites are white. The pygofer is also white. Adults can be both macropterous and brachypterous, with brachypters similarly colored as macropters. Brachypters have infuscate wings, a white stripe along the apex, and a darkened spot near the apex of the clavus. Adult male macropters have a body that is 1.8-2.1 mm long, female macropters are 2.1-2.3 mm; male brachypter bodies are 1.8-1.9 mm. (Weglarz & Bartlett, 2020)
There is a lot of variation in color for this species, with some specimens dark with the vitta faint and marking stramineous and other specimens light with white markings and distinct vittas. (Weglarz & Bartlett, 2020) |
