Scutum: Scutum is very slightly wider than long. Cervical grooves consist of
narrow elongate, deep pits tapering to a point at mid-length of scutum and sepa-
rated from anterior margin by a short shallow groove. Punctations are essentially as
in male. Genital operculum is approximately twice as wide as long. Spiracular
plates are ovoid.
Legs: Coxa and trochanters are with spurs similar to those of male.

Length is approximately 1.5 mm, breadth 1.1 mm.
Capitulum: Basis capitulum is dorsally approximately 2.2 times as broad as
long; external margins are straight; cornua are broadly triangular, approximately
one-fourth as long as the base of basis capitulum. Palpi are campanulate.
Hypostome is as long as palpi, and dental formula is 2/2, with seven to nine denti-
cles in a file.
Scutum: Scutum is approximately 1.3 times as broad as long; margin is broadly
convex, broadest approximately at mid-length. Cervical grooves are narrow.
Punctations are obscure, in five to eight pairs. Spiracular plates are narrow oval.
