Genus Delegorguella Spinola

Delegorguella Spinola 1850: 73 ; Stål 1876: 127.

Paramecocoris Stål, 1861: 199 ; 1865: 111-112; 1876: 52, 53; Lethierry and Severin 1893: 110; Kirkaldy 1909: XXXIII, 1 (Paramecocoris = Delegorguella Spinola 1850, nec Caystrini); Kirkaldy 1909: 206; Jeannel 1913: 38; Hesse 1925: 19; Van Duzee 1929: 92; Linnavuori 1975: 31; 1982: 68, 71, 72.

Body of moderate size; oblongate; generally ochraceous with brownish punctures; head distinctly broader than long; paraclypei longer than clypeus and enclosing the later; antennae with basal segment never reaching to head apex, second antennal segment equal to third but slightly shorter than fourth; labium reaching to mesocoxae; pronotum more than 2x broader than its length, anterior angles slightly toothed or subrounded, humeral angles subrounded, posterolateral margins somewhat straight, lateral margin slightly convex, anterior margin wider than head width; scutellum broad and rounded at apex; abdomen distinctly exposed at repose; metathoracic scent gland ostioles small, peritreme of moderate size.

Male genitalia:

Pygophore with lateral lobes prominent, dorsomedian surface concave, ventromedian margin usually slightly notched; parameres slightly F-shaped, apex broad and usually rounded; inflated aedeagus with dorsal and ventral pairs of membranous conjunctival appendages.

Female genitalia:

Posterior margin of first gonocoxae deeply concave; ninth paratergites large, just reaching posterior margin of fused eighth paratergites.

Comparative note:

This genus is most closely related to Erachtheus in having labium reaching to mesocoxae and antennae with second and third segments subequal in length but it can easily be separated from the same in having antennae with fourth segment longer than third and paramere with apex of blade unilobed, dilated.

Distribution:

Ethiopian region.

Type species: Delegorguella elliptica Spinola 1850 .
