Until now, <i>C. testaceous</i> was known only from females, whereas <i>C. zetteli</i> was described based solely on the male. Since both species were collected together on the same host plant, it had been suggested that they might be conspecific (Tatarnic & Cassis 2008). In the present study, we also collected a series of both male and female specimens with identical external morphology on <i>Macaranga tanarius</i>. However, in the male of this species, we found that the left paramere and endosoma are similar to those of <i>C. zetteli</i>, whereas the right paramere differs and instead resembles that of <i>C. sommelieri</i>, thereby confirming that <i>C. testaceous</i> is distinct. In the female, the paragenital opening is absent, whereas in <i>C. sommelieri</i> it is clearly visible (see fig. 19A–C in Tatarnic & Cassis (2008)), which further supports the identification of this species as <i>C. testaceous</i>.</p> |
