Galapagos Species Database

This species can be recognized by its dark color and large size; in those two characters it differs markedly from E. /eleupi, but it is very similar to E. perryvriesi at first glance. The males of E. perryvriesi are easily distinguished by their elongate hair pencil near the base of the underside of the forewing. The male genitalia are very similar in both species but the median piece on the vesica of E. perryvriesi is about half as long as the dorsal crest of spines while it is longer than the crest of spines in £. galapagosata. The females of the two species can only be separated by their genitalic features. Those of E. galapagosata are characterized by an enlargementof the sclerotized part of the corpus bursae on the left side posteriorly, beside the ductus bursae, and by the smaller and much less strongly sclerotized spicules of the anterior membranous part of the corpus bursae (Landry & Rindge, 1995).
