Description. Male holotype. Length 1.3 mm, width 1.0 mm; body elongate, oval, elytron with side straight, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny, lacking microsculpture. Color dark brown (Fig. 211); head with yellow macula composed of 3 vittae extended from apex of vertex to clypeus, middle vitta slightly shorter than lateral vittae; pronotum with reflexed lateral margin reddish brown; antenna, tibiae yellow; mouthparts yellow except apical maxillary palpus brown with yellow apex; femora brown; ventral surface dark brown except abdomen yellowish brown. Head punctures large, separated by a diameter or less; pronotal punctures smaller than on head, separated by a diameter or less; elytral punctures slightly larger than on pronotum, separated by less than twice a diameter; prosternal, mesosternal punctures large, separated by less than a diameter; metasternum with large punctures along anterior and lateral borders, punctures on remaining surface absent or small, sparse; punctures on abdominal ventrites 1, 2 large, separated by less than twice a diameter, punctures on remaining ventrites small, separated by about a diameter. Head densely pubescent, frons widened from vertex to clypeus, slightly wider than width of eye measured at vertex (Fig. 212); eye canthus short; apical maxillary palpomere long, narrowed to apex in apical 1/3. Pronotum widest at middle, reflexed lateral margin wide, equal in width from base to apex. Epipleuron flat, wide in basal ½, as wide as pronotal hypomeron. Prosternum as wide as long, about as long as mesosternum, apical margin arcuate, without anterolateral projection. Postcoxal line on ventrite 1 long, extended about ½ distance to apical margin of ventrite. Apex of ventrite 5 broadly, weakly emarginate medially. Genitalia with basal lobe about as long as paramere, slender, parallel sided from base nearly to apex, apex broadly emarginate; paramere wide, slightly curved dorso ventrally, of equal width from base nearly to rounded apex, dorsal margin without serrations (Fig. 213); sipho slender, apical 1/4 sinuate (Fig. 214).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; BOLIVIA: Yhancaroinza, Chuquaca, Apr. 1924, coll. G.L. Harrington. (USNM).

Remarks. This species is distinguished with certainty from other brown to black species of Neaporia by shape of male head macula, male genital structure, and Bolivian type locality. The holotype is described from a completely disarticulated specimen with parts glued to a point.
