lows: Coxa with spurs are relatively somewhat shorter; pulvilli are often shorter.

Overall body length is approximately 1.1 mm, breadth approximately 0.6 mm.
Capitulum: Basis capituli are dorsally approximately 3.1 times as broad as long;
cornua are very small, triangular, approximately one-fifth (or less) as long as the base
of basis capitulum. Palpi are broadly salient posteriorly (leachi-type); combined
breadth is approximately 1.6 times that of basis capitulum. Hypostome is as long as or
slightly longer than palpi; dental formula is 2/2, with denticles in files of six or seven.
Scutum: Scutum is 1.3 times as broad as long; greatest breadth is near mid-
length; margins are broadly rounded. Cervical grooves are as an arc, extending to
posterior margin of scutum. Punctations are few, small, and setiferous.
Legs: Coxa I to III are each with spur broadly triangular, extending somewhat
beyond coxal margin; IV with spur reduced to small, broadly rounded ridge on
margin.
