Capitulum: Basis capitulum is dorsally approximately 1.9 times as broad as
long; external margins are essentially straight; cornua are broadly triangular,
approximately one-fourth as long as the base of basis capituli, bluntly pointed api-
cally. Palpi are compact; setae number five dorsally, three or four ventrally.
Hypostome is somewhat shorter than palpi; narrow posteriorly, small hooklets in
five or six dense rows; dental formula is 5/5, with denticles in files of six to nine.
Scutum: Scutum is smooth, glossy, flat, and 1.26 1.31 times as long as broad.
Cervical pits are small, sub-circular, deep, and sub-anterior. Cervical grooves are
obsolete. Lateral grooves are narrow, distinct, extend to the level of coxa III,
enclose first festoon; surface lateral of grooves is somewhat bulging. Punctations
are shallow but distinct, small and medium size, concentrated chiefly posteriorly
and anterolaterally, fewer or absent elsewhere. Festoons number 11. Spiracular
plates are ovate, 1.5
1.8 times as long as broad.
Legs: Legs are long and narrow. All coxal spurs lengths are sub-equal.
