DESCRIPTION

Small species, short and wide, with punctuations on the dorsal surface.Pronotum( Fig.2C ) with low but well delimited protuberances. Fore femora ( Fig. 1D ) with ventro-anterior margin with three to five spines, of roughly the same size, the more apical one generally farther from others especially in males. Male subgenital plate ( Fig. 1B ) with a medium space between styli, angularly curved.

Male genitalia ( Fig. 1 H-J)

Sclerite L2d strong with a long and thin apex. L2v heavy, with a large sclerotized dorsal area and with an apical inner rounded part, and a ventral elongated and narrow part. L3 with a long and narrow apex. R3d with a blunt processus and an elongated basis with a rounded apex. R2 heavy but not wide.

Female genitalia ( Fig. 1 N-P)

Basivalvulae ( Fig. 1O ) rounded with an inner margin irregularly sclerotized. Laterosternite IX ( Fig. 1P ) short, polygonal rather than triangular, with a short ventral apex. Spermatheca ( Fig. 1N )

with a large and rounded apical ampulla, and a curved basal ampulla on a short duct.

DNA sequences

The mitochondrial genes 12S and 16S have been partly sequenced for that species and are available on line in the EMBL database under the accession numbers AJ519680 and AJ519681 respectively.
