Aegilips atricornis Fergusson, 1985: 813 (♂).

Diagnosis

Species very similar to A. nitidulus , from which it can be distinguished by the presence of incomplete notauli, the absence of median mesoscutal furrow and carinate sculpture on the mesoscutum (notauli complete, median mesoscutal furrow present and mesoscutum with some transverse carinae in A. nitidulus ). It can be distinguished from A. flavidicornis , A. longicellus , A. paucus and A. zaitzevi (which also lack complete notauli) despite having incomplete notauli, they are clearly excavated, almost complete in some individuals (notauli very superficial and never exceeding than one third of the scutellum length in A. flavidicornis , A. longicellus , A. paucus and A. zaitzevi ).

Lateral mesoscutum smooth and glabrous, except for some short hairs; parapsidal signum absent, parascutal sulcus very tenuous and not internally carinate ( Fig. 3e ). Scutellum strongly areolate and triangularshaped, not apically rounded, 0.6 times as long as mesoscutum; scutellar foveae square-shaped, large and smooth, posteriorly defined by carina; presence of superficial and narrow pit next to inner margin of scutellar foveae.

Mesopleural triangle smooth except for an oblique sulcus near its anterior margin; short hyaline seta present. Metanotal troughs coarsely sculptured, almost glabrous. Lateral propodeum with strong coarse sculpture; central propodeum glabrous, coriaceous, and divided in two symmetrical areas by median longitudinal carina; lower central region and rest of propodeal surface divided into smaller cells.

FORE WINGS. Pubescent, marginal pubescence denser at apical third. Radial cell closed, 2.3 times longer than wide. Vein 2rm absent.
