Genus Pseudohesperus Hayashi, 2008

The genus Pseudohesperus was characterized in great detail by HAYASHI (2008): the genus is closely allied to Bisnius Stephens, 1829 and Gabrius Stephens, 1829 , because of the similar structure of protarsi, but is easily distinguishable from them by the following characters: (1) mesoventrite strongly convex medially in a subtriangular form, without a transverse carina; (2) male sternite 9 with a pair of long appendages and without any long erect bristles; (3) female second gonocoxite very slender and long; (4) chaetotaxy of the pronotum composed of only a pair of anterolateral macrosetae, basolateral setae absent; (5) gular sutures gradually convergent posteriad to the neck constriction, not parallel in posterior (basal) half.
