Regions clearly demarcated, raised; surface covered by many small tubercles, granules and/or short spines. Pseudorostrum short, usually with wide U-shaped cleft. Supraorbital eave wide curved, preorbital spine formed by proximal edge of eave; 1 small intercalated triangular spine, usually separated from adjacent structures by visible gap; postorbital and suborbital lobes surround orbit. Hepatic region with tubercles and granules, sometimes spines; gastric region raised with large granules or tubercles; cardiac region prominently raised with 1 large median tubercle; branchial region raised, covered with granules and tubercles; metabranchial region with 1 blunt tubercle. Antennal flagellum very short, not extending beyond short pseudorostral horns. Basal antennal article broad short covered by short setae. Third maxilliped with merus and ischium smooth or covered with tubercles, merus may be fused with ischium; merus with anteroexternal angle produced to differing degrees.
