Genus ENNIUS Stål

Ennius Stål 1861: 199 ; 1876: 52, 53; Lethierry and Severin, 1893: 110; Kirkaldy, 1909: 206; Gillon, 1972: 322; Gross, 1975: 220; Linnavuori, 1982: 68, 72.

Paramecocoris (Ennius) Stål, 1865: 112 .

Body medium sized (8.6 mm -11.3 mm); elongate; generally light brown with brown or dark brown punctures; head broader than long; paraclypei longer than clypeus and enclosing the later; antennae with basal segment equal or shorter than head apex, second antennal segment longer than third but shorter than fourth; labium reaching or passing beyond mesocoxae; pronotum with lateral margins straight or slightly convex, anterior angles slightly toothed, humeral angles subround; scutellum long and round at apex; metathoracic scent gland ostiole small with large peritreme.

Male genitalia

Pygophore quadrangular, lateral lobes prominent, dorsomedian surface deeply concave, ventromedian surface slightly notched; paramere some what F-shaped with curved blade; aedeagus with large conjunctival appendages, paired.

Female genitalia

Posterior margin of first gonocoxae convex; ninth paratergites small and not reaching posterior margin of fused eighth paratergites.

Comparative note This genus is most closely related to Munshiana Ahmad and Kamaluddin , Stysicoris Ahmad and Kamaluddin , Dorpius Distant and Myrochea Amyot and Serville in having antennae with second segment distinctly longer than third in length but it can easily be separated from the same in having second antennal segment slightly longer than third and metathoracic ostiolar complex with peritreme large, anteriorly curved.

Distribution Ethiopian region.
