Description.

In addition to characters in the genus description, the species is characterized by the following primary and secondary male sexual characters. Sternite VIII without apical incision. Tergite X apparently fused to internal face of lateral sclerites (Fig. 5A View Figure 5 , solid line), with two large setae situated at apical third of length (Fig. 5A View Figure 5 ; LS). Sternite IX emarginate apically, with symmetrical basal stem (Fig. 5A View Figure 5 , dashed line). Lateral tergal sclerites and tergite X of approximately equal length. Aedeagus (Fig. 5B, C View Figure 5 ); paramere longer than and closely attached to, median lobe (Fig. 5B View Figure 5 ); lateral apical area of paramere with setae of varying length (Fig. 5C View Figure 5 ; ST); internal sac consisting of a pair of heavily sclerotized oblong-shaped sclerites (Fig. 5C View Figure 5 ; OS) and pair of weakly sclerotised longer, more slender sclerites extruding from apical area of median lobe under pressure (Fig. 5C View Figure 5 , SS).

Distribution.

Based on the specimens studied here, the new genus is restricted to the lowland areas of the Amazonian basin of Peru (Fig. 6 View Figure 6 ). As a fully winged species known only from six specimens from two areas approximately 1000 kilometres apart from each other, it seems to be a widespread species, perhaps much more than it appears now.

Bionomics.

Same as above.

Etymology.

The species is named in honour of Aslak Kappel Hansen (NHMD) who was one of the collectors of this new genus and who brought our attention to its unusual nature compared to Heterothops .

Comments.

It is notable that a species of Heterothops ( Amblyopinini ) was obtained during the same collecting event as one of the Amazonothops specimens. This shows that these two similar looking, yet phylogenetically distant (Fig. 1 View Figure 1 ) taxa co-occur, probably in similar or the same microhabitats in the Amazon basin.
