ALEIXUS McDONALD, 1981

Aleixus McDonald , in Rolston and McDonald, 1981: 259–260.

TYPE- SPECIES: Aleixus virgatus McDonald , by original designation.

DIAGNOSIS: The addition of a new species in Aleixus requires a rearrangement in the generic diagnosis as given by Rolston and McDonald (1981) and Rider (1994). Head: distinctly declivent at apex; antennal segment Inot reaching apex of head; antennal segment II and III cylindrical, segments IV and Vsomewhat inflated; antennal segment II longer than any other segment; juga surpassing clypeus, obtuse at apex, not contiguous anteriorly. Rostrum reaching metacoxae. Thorax: Pronotum with humeral angles with large tubercles, dorsally bifid and black at apices; tubercles ventral surface bearing a short blunt projection. Scutellum subtriangular, apex broadly rounded not reaching apices of coria. Thoracic sterna nearly flat. Peritreme acuminate apically, extending at least beyond middle of evaporatorium. Legs: with dorsal surface of femora produced distally. Abdomen: Abdominal spine small, not reaching between metacoxae. Characters used as diagnostic to the genus and found to be variable between the two species include length of the humeral angles, development of the tooth placed distally in the femora, length of the peritrema, and shape of tibia (see also comments in the description of the new species).
