Mean body length is approximately 3.2 mm and width is 2.1 mm.
Capitulum: Basis capitulum is dorsally approximately 1.6 times as wide as
long; cornua are approximately one-fourth as long as base, widely triangular, apex
bluntly pointed. Palpi are compact, lacking basolateral salience. Hypostome is as
long as palpi; outline is sub-parallel laterally; dental formula is 5/5, with denticles
in files of 10
12 of which anterior and posterior two or three are smallest.
Scutum: Scutum is bordered laterally. Lateral grooves are indistinct, indicated as
short, shallow depressions marking juncture between sloping scutal surface and lat-
eral ridges, extending from anterior festoon to the level of coxa II or III. Cervical
grooves are short, deep, sub-parallel. Punctations are shallow, more or less discrete,
moderately numerous, irregularly arranged and distributed. Festoons number 11.
Legs: Coxa are each with a prominent spur; spur of I is peg-like, narrowly elongate,
bluntly pointed apically, overlapping apical margin of coxa II; spurs of II and III are
sub-equal, short, widely triangular, median, extending to but not overlapping following
coxa; spur of IV is also triangular but shorter, situated close to inner margin of coxa.
