Scutum: Scutum is flat or very slightly convex between deeply depressed lateral
grooves and elevated lateral ridges; 1.5 times as long as wide; lateral margins are
almost straight and parallel, or slightly convex. Lateral grooves are long, distinct,
extending anteriorly to the level of coxa III, posteriorly enclosing two festoons.
Cervical grooves are very narrow, converging from anterior emargination of scu-
tum to short, deep, rounded cervical pits. Punctations are practically obsolete, a
few shallow punctations may be present. Festoons number 11, exceptionally long,
distinctly separated.
Legs: Coxa each is with an elongate spur; spur on I is longest, parallel sided,
bluntly rounded apically; spurs on II, III, and IV are shorter, sub-equal, elongately
triangular.
