Taxonomic notes
Arsipoda evax
shares a thickset, ovoid body with
A. atra
sp. nov.
,
A. povilaensis
sp. nov.
and
A. transversa
sp. nov.
(
Figs 1B, F
,
2D, I
). It can be easily distinguished by the smaller size and the black, metallic integuments, (
A. atra
sp. nov.
is black, but not metallic;
A. povilaensis
sp. nov.
is yellowish;
A. transversa
sp. nov.
is reddish). Genitalia are also clearly distinguishable (
Figs 8C, G
,
9E
,
10A
,
11B, F, L, P
).
Median lobe of aedeagus (
Fig. 8G
) in ventral view laterally parallel; apex subtriangular, slightly rounded, with generally elongate median tooth; ventral surface with a shallow median depression at apical third; in lateral view median lobe clearly and regularly curved in basal ¾s and straight in apical ¼; dorsal ligula short – from apical third to apical part of median lobe of aedeagus –, wide, apically thinner. Spermatheca (
Fig. 11F
) with pyriform basal part; collum moderately elongate, about twice as long as apical part; ductus elongate, thickset, apically inserted.
