Recognition:
Brachypterous, leaving several terga visible from above, tegulae hidden (all Orgeriinae); callosity present behind eye; head more than 2x length of eyes; cephalic process, as seen from the side, truncate at the extremity, five angled, gradually tapering.
Keys to genus of US Orgeriinae in Doering & Darby 1943 and Doering (1955). Also, Key to genus in Melichar 1912: 180.
Description of genus from Ball and Hartzell 1922: 139-140.
Resembling Orgerius Stal but with the vertex produced into a long stylate process, similar to that found in Scolops, but stouter.
Cephalic process long, tapering, nearly twice the length of the eye, truncate apically, but slightly inclined to the plane of the vertex. Front straight in profile, tricarinate, the lateral carinae narrowing near the apex but not uniting with the median. The carina from the lower corner of the eye running obliquely to the upper margin of the snout at or beyond the middle; below this carina, the front is pustulate. A transverse carina sets off the posterior third of the vertex; median carina of the vertex extending onto the cephalic process a slight distance. Eye separated from the pronotum by an elongate callosity. Pronotum with a central raised tablet, tricarinate, the lateral extensions sloping strongly downward and backward, pustulate. Elytra covering the second segment of the abdomen, irregularly reticulate; a row of pustules near the posterior border of each segment. Legs long, slender, terete; hind tibia with 5-6 weak spines. Rostrum about equaling the abdomen. Type of the genus O. acuta Ball.
This genus as now restricted, with acuta Ball as type, includes two species known only from Southern California and Lower California, Mexico. The slender tapering cephalic process will at once separate them from other groups.
Key to the Species of Orgamara.
A. Cephalic process long and slender, nearly twice as long as the eye; the anterior tablet of the vertex longer than wide … O. acuta Ball
AA. Cephalic process broader and shorter, extending beyond the eye, but little more than its length; anterior tablet of vertex rectangular … O. reducta Ball
