status

 

Pronomaea procerula ASSING   , in press ( Map 5 View Map 5 )

Additional material examined: Iran: 2 exs., Kordestan, N Sanandajd, 35°28 'N, 47°01 'E, 22.VI.1975, leg. Senglet ( MHNG, cAss) GoogleMaps   .

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 View 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.
