Amphimela citri ( Bryant, 1922)

Type specimens examined: HOLOTYPE ♂: Ghana: Ojesu, Ashanti (A. E. Evans) ( BMNH). PARATYPES: Gold Coast, Aburi, 9.II.1916, W. H. Patterson (♂, BMNH); Ojesu, Ashanti (A. E. Evans) (♀♀, BMNH).

Body shape elliptical, convex (LB = 5.4 mm); bluish-black, with two reddish-brown large spots on the subbasal part of elytra and two small spots on frons ( Fig. 8 ). Head very finely punctured; labrum yellow, with apical margin curved; clypeus short; with two small reddish-brown spots on frons ( Fig. 10 ); mandibles dark and pointed; eyes elliptical, large; antennae filiform, reddish-brown basally, segments 5th–11th darker. Prothorax bluish-black (LP = 1.1 mm), finely and evenly punctured, transverse, maximum pronotal width at base (WP = 2.5 mm); with lateral sides margined and narrow margins apically and basally; anterior angles produced and acute, posterior angles pointed. Scutellum triangular, bluish-black (reddish in some individuals). Elytra bluish-black, with two large reddish-brown spots sub-basally behind humeral callus; elongate (LE = 3.5 mm); broader basally than apically with maximum elytral width at basal half (WE = 3.0 mm), sparsely punctate-striate, with intervals finely punctured; humeral callus slightly protruding. Legs reddish-brown to dark brown; hind femora swollen; a small spine at apex of hind tibiae; all tarsi with a pad of setae ventrally. Ventral surface reddish-brown; sternites strongly punctured; first abdominal segment strongly punctured and densely setose, remaining segments with scattered punctures and slightly pubescent. Male with last abdominal segment sinuate (rounded in female).

Paratypes similar in habitus and markings to the holotype. Measurements of one male: LB = 5.1 mm; LP = 1.0 mm; WP = 2.4 mm; LE = 3.3 mm; WE = 2.9 mm; LA = 1.99 mm; Median lobe of aedeagus in ventral view parallel and narrow basally, venter with oval groove (LA = 1.99 mm) and apically with rounded tip; in lateral view, median lobe curved, ( Figs. 24, 25 and 26). Females generally slightly larger than males (measurements of females: LB = 5.5 & 5.6 mm; LP = 1.0 & 1.1 mm; WP = 2.6 & 2.7 mm; LE = 3.6 & 3.8 mm; WE = 3.1 & 3.2 mm; LS = 0.43 mm). Spermatheca hook-shaped and duct sclerotized ( Fig. 27).
