Comments So far only known from male specimens. The status of the type material of A. nigroapicalis is given by Goodger & Watson (1995: 5) as 'syntype(s)', but the original description (l.c.) is evidently based on a single specimen said to be a female from the Staudinger collection. As the malespecimen in MNHU listed above agrees well with the description and has all corresponding labels, it is here regarded as the holotype. |
