Morphological terminology follows
Body robust, stramineous with dark markings on intracarinal region of face (anterior to the Y-shaped carina of vertex), including areolet, genae, and usually also lateral portions of abdominal terga. Body not compressed (unlike
Male terminalia with pygofer rather quadrate in lateral view, dorsocaudal margin of pygofer weakly projecting. Opening of pygofer broad, wider than long, with lateral margins of opening carinae, ventral margin smoothly rounded. Diaphragm strong and conspicuous, dorsal margin broadly U-shaped, bearing median, bilobed armature subtending the aedeagus, much wider than tall. Parameres exerted through broad opening in diaphragm; parameres strongly flattened, sides subparallel, strongly diverging, basal and apical angles weakly developed. Aedeagus widest in basal third, then abruptly narrowed with distal 2/3 strongly downcurved; suspensorium U-shaped, weakly apparent. Segment 10 broad, bearing strongly developed pair of weakly sinuate processes on caudal margins near lateral margins. Segment 11 about 2/3 height of segment 10.
Macropters darker than brachypters, with abdomen and lateral portion of mesonotum more strongly embrowned. Macropterous wings are clear (no dark marking at apex of clavus), exceeding length of abdomen nearly by length of abdomen.
