GEYERIA BUCHECKER, [1880] ( FIGS 28, 29)

S PILOPASTES HOULBERT, 1918 SYN. NOV.

Type species

Castnia decussata Godart, [1824] Included species

Geyeria decussata (Godart, [1824]) , Geyeria strigata ( Walker, 1854) stat. rev., G. galinthias ( Hopffer, 1856) (Spilopastes) comb. nov.

Comments

Synapomorphic characters for the wing pattern (15: 2), length of uncus (67: 0), morphology of gnathos (84: 2), signa (97: 1), and shape of female eighth abdominal tergite (109: 2) support this arrangement of genera, with the synonymization of Spilopastes under Geyeria .

We considered G. strigata , which was synonymized by Lamas (1995) under G. decussata , to be a valid species because of the distinct wing pattern as well as characters of the valva and ductus bursae that are slightly different from those of G. decussata ( Fig. 29). The other two species formerly included in Geyeria , e.g. Geyeria hubneri ( Fig. 15) and Geyeria uruguayana ( Fig. 2), possess morphological attributes that are not related to the nominative genus.
