Redescription of Amerila abdominalis (Rothschild, 1933), a little-known species of tiger moth from Southeast Asia (Lepidoptera: Erebidae: Arctiinae)

Abstract

The genus Amerila Walker, 1855 is widely distributed from Africa to Australia with the maximum diversity in Africa (Häuser 1993, Häuser & Boppré 1997). Three species in this genus are recorded from Indochina (Dubatolov & de Vos 2010), including A. astreus (Drury, 1773) and A. omissa (Rothschild, 1910). These two are common and widely distributed, and their external morphology is well studied (Holloway 1988, Černý & Pinratana 2009, Bucsek 2012) and their genitalia are illustrated in the book of Dr. J.D. Holloway (1988). However the third one, A. abdominalis (Rothschild, 1933) is a rather poorly known species. The morphology of this species is known only from its original description (Rothschild 1933). There are no published images of genitalia of this species, and its female morphology is unknown. The image of a male of A. abdominalis was published by Bucsek (2012). Here, we give the detailed description of the morphology of A. abdominalis, including the male and female genitalia.
