Type material. Holotype: ♂, New Guinea: (NE) Wau, Morobe District; 2500m; 28/12/1961; leg. J., J.H. & M. Sedlacek, G. Monteith and Native Collectors (BPBM). Paratype: 1 ♀, same data as the holotype (BPBM).
Description. Head dorsally black, surrounded by a pale orange band along lateral margins of paraclypei, and a diffuse spot of the same color on each side of neck (Fig. 1). Paraclypei long, contiguous, with transverse rugae on dorsal surface. Clypeus small, with sparse concolorous punctation. Eyes large, prominent, somewhat pedunculate; ocelli reddish. Antennal tubercles small. First antennal segment slightly surpassing apex of head; second segment longest, thinnest, fourth longer than third.
Pronotum matt. Pronotal punctation finer, denser towards anterior margin. Medial longitudinal line of pronotum impunctate, reaching about half way from anterior margin. Cicatrices small, drop shaped, with very fine, sparse punctation (Fig. 1). Scutellum matt in color with uniform punctation (Fig. 1). Clavus narrow, with small, lateral hump at the base, punctation uniform. Corium slightly iridescent, with a porous texture. Membranous part of wings with iridescent green flecks. Thoracic sterna orange, with irregular, diffuse black spots medially. Mesosternal carina small, variable in color (Fig. 2). One pair of thoracic spiracles. Legs yellow, each with a brown band, covered by yellowish pilosity, pro- and meso- tibiae broadened apically.
Abdomen yellowish with irregular black patterns medially. Abdominal spiracles slightly oval, peritreme surrounding each spiracle black.
Female genitalia (Fig. 6): first gonocoxae short, laterally elongate, with abundant caramel colored pilosity. Distal margin of each gonocoxite undulate, forming a semi-bilobed shape. Second gonocoxae small, fused, rectangular in shape. Tenth abdominal segment exposed, square with distal margin concave. Paratergites 8 with square darker margins. Paratergites 9 fused, smooth, bilobed. Male genitalia (Figs. 5, 7, 8): posterior end of pygophore transversally flattened; posterior margin undulate, concave medially, with a rounded projection on each side. Surface in caudal view darker than rest of structure. Parameres dark brown, lobate, embedded transversally on top of aedeagus in caudal view.
Measurements (in mm): male holotype (female paratype in parenthesis): Total body length: 13.07 (16.02), pronotum width: 7.05 (8.15), pronotum length: 3.92 (4.67), head length: 1.74 (2.08), head width: 2.32 (2.49), scutellum length: 4.00 (4.87), scutellum width: 3.60 (4.20). Antennomeres: I = 0.8 (1.01), II = 2.25 (2.53), III = 1.88 (–), IV= 2.63 (–). Rostrum: I = 0.97 (1.20), II = 1.30 (1.38), III = 0.64 (0.68), IV = 0.77 (0.82).
Etymology. The specific epithet is Latin adjective composed of flavo- (= yellow) and -lateralis (= sided). This species is named for the yellowish lateral ornaments.
