Redescription.

Length: 1.4-1.5 mm. Body oval and elongated, slightly convex. Yellowish-brown. Pubescence simple. Metathoracic wings fully developed.

Head. Large eyes (L = 0.122 mm), normal, sub-hemispherical and protruding (E ≥ 1) with facets (E ≥ 1) smaller or as large as head punctures ( Ø = 0.09 mm). Long antennae (Fig. 20) (L = 0.543 mm) surpassing the base of the pronotum. 1st antennomere thick and ovoid; 2nd as long as 1st but narrower; 3rd 1.1 times longer than 2nd; 4th, 6th, 7th and 8th almost identical and half as long as 3rd; 9th and 10th transverse.

Pronotum (Figs 19, 21) convex and slightly transverse (RD = 1.9). Large callosity (1/3 as long as the side), not protruding from the lateral margin of the pronotum. Callosity side clearly visible from above. Gland pore visible. Callosity margin strong. Callosity forming an obtuse angle rearwards and a 26.62-27.99°angle with the body axis. Lateral margins converging towards the base. Posterior angles obtuse. Groove and basal foveae present. Strong and thick punctation, punctures separated by a shorter distance than their diameter ( Ø = 0.013-0.016 mm).

Elytra with punctation thinner and more scattered than that of the pronotum. Punctures separated by a distance larger than their diameter ( Ø =0.0 11-0.013 mm).

Aedeagus (Fig. 23) (L = 0.153 mm) apically extended. Basal third of lateral margins with a strong protuberance. Endophallic orifice visible. Endophallic armour made up of minute thorns. Parameres (L = 76.75 µm) (Fig. 22) triangular and very elongated. Two or three apical setae. Few pores with and without setae.

Biology.

Some specimens have been captured on Senecio sp.

Distribution.

Madagascar ( Grouvelle 1896); Cameroon ( Bruce 1952, 1959).
