Amphimela quadrinotata ( Bryant, 1936)

Type specimens examined: HOLOTYPE ♂: Uganda: Kampala, 9.IV.1934 (H. Hargreaves) ( BMNH). PARATYPES: Uganda: Kampala, 11.IV.1934 (H. Hargreaves) (♂, BMNH); Uganda: Kampala, 10.IV.1934 (H. Hargreaves), (♀, BMNH), Uganda: Kampala, 9.IV.1934 (H. Hargreaves) (♀, BMNH).

Body shape elliptical, convex, small (LB = 3.3 mm), bluish-green-, with four large reddish-brown spots on the elytra ( Fig. 7 ), 1st–5th antennal segments, tibiae, tarsi, coxae and abdominal sternities reddish-brown. Head greenish-blue ( Fig. 11 ), finely punctured, labrum black and impunctate with curved anterior margin; clypeus short; antennae passing a little base of elytra, the first basal segments from 1-5 reddish-brown, and the rest darker and slightly pubescent. Prothorax bluish-green (LP = 0.5 mm), finely and evently punctured, transverse, with maximum pronotal width at base (WP = 1.4 mm) and strongly contracted in front, lateral sides margined. Scutellum triangular, impunctate, bluish-green. Elytra bluish-green (LE = 2.4 mm), with four large reddish-brown spots, sub-cylindrical, maximum elytral width at basal half (WE = 1.9 mm), rounded at apex, finely sparsely punctate-striate, feebly toward apex, with intervals finely punctured; humeral callus feebly protruding. Coxa, tibiae and tarsi reddish-brown; femora bluish-green; hind femora swollen; a small spine at apex of hind tibiae; all tarsi with hair pad ventrally. Ventral surface reddish-brown; sternites strongly punctured; first abdominal segment punctuated and with dense hairs, the 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 male (n=1): LB = 3.4 mm; LP = 0.6 mm; WP = 1.5 mm; LE = 2.5 mm; WE = 1.8 mm; LA = 1.07 mm); Median lobe of aedeagus in ventral view parallel in ⅔ and narrow basally, with narrow groove underside (LA = 1.07 mm) and apically with rounded tip; in lateral view, median lobe bent in ⅓ of its length, ( Figs. 20, 21 and 22 ). Females generally slightly larger than males (measurements of females: LB = 3.5 & 3.6 mm; LP = 0.5 & 0.7 mm; WP = 1.3 & 1.9 mm; LE = 2.5 & 2.9 mm; WE = 1.6 & 1.9 mm; LS = 0.34 mm). Spermatheca narrow, converted C-shaped with very small base and sclerotised duct ( Fig. 23 ).
