Eriopithex Warren Gen. rev.

Type species: lanaris Warren.

In facies this genus is similar to some Gymnoscelis Mabille, finely and rather obliquely fasciated, with the angles of the postmedials slightly bilobed, and a similar but simply angled antemedial. However, the hind-tibia has two pairs of spurs, leading to the genus being placed in synonymy with Chloroclystis. Genitalic features indicate that lanaris does not fall readily into any other grouping of the complex, therefore Eriopithex is revived. The apodemes of the second tergite are set rather close together, each relatively short, tongue-like.

The male abdomen has well-developed octavals as illustrated with characteristic asymmetrical subapical expansion and apical spining. The uncus is reduced, the tegumen extended in a narrow triangle with a rounded apex. The saccus has a central longitudinal bar of thickening as in Gymnoscelis, but the valves lack coremata or hair pencils, and are themselves rather short, with a somewhat stepped ventral margin. The aedeagus is narrow, with two rather blunt cornuti in the vesica.

In the female the ductus is long, narrow, sclerotised, ribbon-like, and the bursa is globular with a rather flocculent thickening. The ductus seminalis arises from distally on the bursae.

A second species, E. recensitaria Walker comb. n. is tentatively combined with Eriopithex purely on the structure of the octavals. There is little concordance in other features except the absence of hair pencils. Inoue (1971) suggested that E. ishigakiensis Inoue comb. n. (Ryukyu Is.) was related to lanaris. It has characters intermediate between lanaris and recensitaria, the octavals not strongly developed, but with the valves of the male more as in lanaris, and the bursa and ductus of the female more as in recensitaria. It is therefore also tentatively combined with Eriopithex.
