discussion
Remarks Comparing the material here with the illustrations of A. walkeri and A. cultricauda (both described as having 3 mm length) there does not seem any reason for accepting two different species. Gn 2 of A. walkeri in Krapp-Schickel (2006 fig. 4) is also less widened than in the original description by Chilton, which would be one of the differentiating characters. In A. claudei sp. nov. (see below) there are similar ' pleats' near the dorsal humps as described for A. cultricauda and it may well be that in some specimens these are more visible than in others. The mandibular palp has three clearly visibile articles and also in other mouthparts there is no difference with the illustrations for A. tuberculatum by Andres (1989: 183 figs 4 - 8, 184 figs 12 - 14).
