Capitulum: Basis capitulum is dorsally approximately 1.7 times wider than its
length; cornua are approximately one-third as long as the base of basis capitulum,
widely triangular, with roundly pointed apex. Palpi compact, lacking basolateral
salience. Hypostome is approximately as long as palpi; lateral outline is slightly diverg-
ing from the base to apex; dental formula is 4/4, with eight to ten denticles in a file.
Scutum: Scutum is approximately 1.4 times as long as wide; posterior margin is
gradually rounded. Lateral grooves are absent. Cervical grooves are short and shal-
low; pits are deep, oval, and short. Punctations rare, some small, some medium
size, and widely scattered. Festoons number 11.
Legs: Coxa each with a prominent, widely triangular spur, margins of which
gradually converge to narrowly rounded apex; spur of I is slightly longer than
others, spurs of II, III, and IV are sub-equal in length.
