Diagnosis:
Highly distinctive species; for a detailed description see ASSING (in press).
Body slender. Antennae and legs conspicuously long and slender, preapical antennomeres not transverse. Pronotum of distinctive shape, almost cordiform: maximal width in anterior half, strongly tapering posteriad; width of posterior margin 0.75-0.80 times maximal pronotal width; lateral margins smoothly sinuate in posterior half. Elytra only with moderately dense puncturation. For illustrations of the habitus, the forebody, and the antenna see figures
23-25 in
ASSING (in press).
♂
: aedeagus
0.45-0.47 mm
long); shape of median lobe somewhat resembling that of
P. flavirostris
, but more slender, ventral process more strongly bent (in relation to base), and internal sac with remarkably long flagellum; for illustrations see figures
27-30 in
ASSING (in press).
♀
: spermatheca of similar shape as that of
P. anatolicaanatolica
and
P. khnzoriani
; for an illustration see figure
34 in
ASSING (in press).
Comparative notes:
The species is readily distinguished from all other representatives of the genus distributed in the Western Palaearctic region and Middle Asia by the distinctly longer and more slender antennae and legs, the conspicuous shape of the pronotum (cordiform shape, sinuate lateral margins), the sparser puncturation of the pronotum and the elytra, as well as by the morphology of the aedeagus, especially the remarkably long flagellum.
Distribution and bionomics:
The known distribution is confined to western
Iran
(
Map 5
); for additional localities see ASSING (in press). It is here reported from
Afghanistan
for the first time. The species has been collected on river banks at altitudes of 1940 and
2040 m
((ASSING in press) in June and July.
Key to the
Pronomaea
species
of the Western Palaearctic region, including Middle Asia
1. Antennae and legs conspicuously long and slender; antennomere X not transverse. Pronotum cordiform, distinctly narrowed posteriad; width at posterior margin 0.75-0.80 times maximal pronotal width; lateral margins smoothly sinuate in posterior half (dorsal view), posterior angles pronounced. Elytral puncturation less dense.
♂
: median lobe of aedeagus shaped as in figures
23-25 in
ASSING (in press), with very long flagellum.
♀
: spermatheca minute and with very short duct (figure
34 in
ASSING (in press)).

P. procerula
ASSING
- Antennae and legs shorter; antennomere X transverse, usually approximatey 1.5 times as wide as long. Pronotum weakly tapering posteriad; width at posterior margin usually approximately 0.90-0.95 times maximal pronotal width; lateral margin not or only indistinctly sinuate in posterior half; posterior angles obtuse. Elytral puncturation denser.
♂
: aedeagus of different shape and with shorter flagellum. ............................................................... B
2. Eyes less prominent and smaller, shorter than postocular region in dorsal view (
