Ventral surface. – Meta-meso ventrite brown, with yellow recumbent setation, finely punctate. Visible abdominal ventrites brown, finely punctate, covered with yellow recumbent setation. Pygidium brown, covered with short, yellow recumbent setation.

Male. – Unknown.

Etymology. – Dedicated to the mother of one of the two authors (Alain Coache), Annette Coache.

Differential diagnosis. – The new species is similar to Litargus (Litargus) raffrayi Grouvelle, 1914 ( South Africa) and L. (L.) crassus Grouvelle, 1914 ( Cameroon) but differs from them by the shape of the elytral pattern and structure of the antennae; from Litargus (Alitargus) balteatus LeConte, 1856 , it differs by the structure of the antennae (short terminal antennomere) and presence of apical elytral spot.
