Charterginus pallidibalteatus Cameron, 1912: 219 . Holotype: ♀ type locality not stated, [ Guyana] (BMNH), examined. Chartergus pallidilineatus: Bodkin 1918: 297–321 .

Pseudochartergus pallidibalteatus: Richards 1978: 154 , 157; Carpenter and Wenzel 1990: 180, 182; Wenzel 1991: 515. Protopolybia pallidibalteatus: Santos-Junior et al. 2015: 174 , 182.

Diagnosis. Length of fore wing 5.71 mm; eyes glabrous; gena narrow, about 0.5 × eye width; body almost completely covered by diminute bristles; pronotal carina laterally very developed, angular; prominence in front of the pronotal fovea developed, short ( Fig. 9 ); pronotal fovea distinct, wide and deep; mesoscutum without conspicuous bristles. Metanotum short, metanotal process with apex narrowly rounded; propodeal valves narrow ( Fig. 10 ). Color black with few marks on front and gena.

Redescription. FEMALE. Length of fore wing 5.71 mm; clypeus narrow, approximately as long as wide (HClp=0.82; MxWClp=0.90; TeW=0.70; MiWClp = 0.80 mm), ventral margin narrowly subtruncated; tentorial pit closer to antennal socket than to eye margin; interantennal area relatively wide, approximately 2 × diameter of antennal socket; mandibles relatively sh

ort, with length 0.60 × times distance between eyes at vertex; gena narrow, about 0.5 × eye width; occipital carina distinct, extending for approximately three fourths of height of gena, fading very close to insertion of mandibles FIGURES 11–22. 11, 12, 13, 14.

( Fig. 28 ); pronotal carina laterally very developed, angular; prominence in front of the pronotal fovea developed, short ( Fig. 9 ); pronotal fovea distinct, wide and deep; length of mesoscutum 0.98 × its width; metanotum short, length of median axis 0.58 × width of central disk, metanotal process with apex narrowly rounded; propodeum with wide and shallow cavity; propodeal valves narrow ( Fig. 10 ); T1 sessile, distinctly wider than long, approximately as wide as T2.

Front, mesoscutum, scutellum, metanotum and propodeum with sparse micropunctation and deeper and stronger mesopunctation; T1–T5 with mesopunctation strong and deep; clypeus with short golden bristles, except on ventral margin, which has elongated bristles; eyes glabrous; mesoscutum with conspicuous bristles; propodeum with short and sparse bristles.

Color black, scape and pedicel ventrally brown, antennomeres and mandibles black to brown; mandibles black with distal region brown, clypeus almost entirely, inner orbit with narrow band which extends to the ocular sinus, outer orbit with narrow band which extends to the occiput; tegulae black, propodeum without dorsal marks; distal margin of T1–T5, with a narrow yellow band. Legs black to brown; wings hyaline, venation brown.

MALE. Length of fore wing 5.50 mm; eyes wide, strongly produced inwards; clypeus narrow, longer than wide, with silvery and long bristles, ventral margin little produced and subtruncated; tentorial pit closer to eye margin than to antennal socket; gena very narrow; color like female. Genitalia. Parameral spine without elongate bristles; basal angle of paramere widened, apical angle narrow (Fig. 19); digitus narrow with apical margin approximately rounded, with few long bristles, basal process acuminate (Fig. 22); cuspis moderately covered by long bristles; ventral process of aedeagus laterally projecting, strongly sclerotized and weakly serrated; preapical region of aedeagus not angular in lateral view (Fig. 20); apex approximately truncated in dorsal view (Fig. 21).
