Description (from Ramme 1929)

Refers to female holotype only ( Fig. 28 View Fig ). (Ramme labelled his Measurements as being from a male, apparently in error.)

[Fastigium slightly concave between the compound eyes, leading apically to a small medial depression, rounded at the front, floor pitted, and with a trace of a longitudinal carinula. Frontal ridge slightly concave above the medial ocellus, and obsolete below the latter. Frons coarsely pitted and wrinkled. The ridge between the 2 nd and 3 rd pronotal sulci inflated only at its lateral extremities. Otherwise, morphology fits the generic description].

Colouration (here newly described from holotype)

Top of head dark olive green, frons was probably yellow with olive mottle. Antennae broken, only fragments remain, but seem to be black. The yellow colour of the frons continues over the genae and joins a yellow band on the ventral edge of the pronotal lobes. Rest of pronotum mostly shiny black, but there are two pairs of dirty yellow spots at the anterior and posterior edges of the disc. Metanotum and first 3 abdominal segments blackish olive-green, with two yellow patches on the dorsum of Abd. 1. Rest of abdomen dirty yellow. Fore and middle legs have red femora and olive-green tibiae. Hind femur dark olive-green, this colour extending along dorsal ridge of knee too. Lateral lobes of knee reddish brown, both internal and external. Condyle of tibia also brown, but rest of tibia dark olive-green, shading to blue-green distally.

Distribution

Known only from the type specimen and type locality. Yambata is WNW of Kisangani, and SE of Bangui ( CAR). It is on the N bank of the Congo River, near the CAR frontier.

Status of taxonomic material

Poor. Male unknown, female holotype has apparently been damaged since Ramme’s description; LHS hind femur is reglued, antennae broken and LHS compound eye missing, now covered with glue. Requires new collections, including the unknown male.
