Dochmioglene crassa (Cameron) comb. n. Figs 4-6

Selandria crassa Cameron, 1883: 19, pl. 1, fig. 5.

Remarks.

Dochmioglene includes about 11 species distributed from Central America to Argentina (Smith, unpublished). The genus has not been revised. The reared specimen ( Figs 4-6 ) agrees with Dochmioglene crassa except for the lack of a black mark on the mesoprescutum. This mark, however, is faint to absent in some other specimens examined.

Dochmioglene belongs in the subfamily Selandriinae , which includes many species associated with ferns. This rearing, and that of the following species, confirms that larvae of many Neotropical selandriine species may be feeding on fern foliage.

Cameron (1883) described the female from "Guatemala, San Isidro 1600 feet" and mentioned that a male from El Tumbador may be the male of the species. Because Cameron did not designate a holotype, apparently included a male, and did not state how many specimens were available, a lectotype is here designated. The female of Selandria crassa in in BMNH, labeled "Type H.T.," "B.M. type: Hym. 1.266," "B.C.A. Hymen. I, Selandria crassa Cam.," "San Isidro, 1600 ft., Champion" and "Selandria crassa Cam., type, BCA Hy 1, 10" is designated the lectotype. The combination in Dochmioglene has not been published and is based on study of the type by DRS.

Distribution.

Costa Rica, Guatemala, Panama, Surinam (Smith, unpublished).

Food plant and biology.

One specimen, 09-SRNP-32388, was found feeding on the foliage of an ACG rain forest fern, Lomariopsis vestita E. Fourn. ( Lomariopsidaceae ).
