Description. Male
holotype
. Length
1.6 mm
, width 1.0 mm; body elongate, slender, elytron with sides slightly rounded, wider than pronotal base, widest anterior to middle of elytra. Dorsal surface entirely shiny, lacking microsculpture. Color black with greenish tint (
Fig. 149
); antenna yellow; mouthparts dark brown; legs dark brown except anterior 2/3 of tibia yellow; ventral surface black except abdominal apex yellowish brown. Head punctures coarse, separated by about a diameter; pronotal punctures slightly larger than on head, separated by less than twice a diameter; elytral punctures slightly larger than on pronotum, separated by less than twice a diameter; prosternal, mesosternal punctures large, separated by about a diameter; metasternum with large punctures along anterior and lateral borders, punctures on remaining surface smaller, sparse; punctures on abdominal ventrites 1, 2 large, separated by less than three times a diameter, punctures on remaining ventrites small, separated by about a diameter. Head with long, sparse pubescence, frons narrow, slightly widened in anterior 1/4 (
Fig. 150
), slightly narrower than eye measured at vertex; eye canthus extremely short; apical maxillary palpomere long, narrowed to apex in apical 1/3. Pronotum widest anterior to middle, reflexed lateral margin narrow, equal in width from base to apex. Epipleuron flat, wide in basal ½, as wide as pronotal hypomeron. Prosternum slender, longer than wide, apical margin slightly arcuate, without anterolateral projection. Postcoxal line on ventrite 1 long, arcuate, extended 2/3 distance to apical margin of ventrite. Apex of ventrite 5 arcuate medially. Genitalia with basal lobe longer than paramere, long, slightly widened from base to distal 1/8 where convergent with emarginate apex; paramere narrow throughout to rounded apex, dorsal margin lacking serrations (
Fig. 151, 152
); sipho long, slender, basal capsule with base broadly, distinctly emarginate (
Fig. 153
).

Specimens examined
. 2. Both
N. viridiscens
and
N. cuprea
were described from unique specimens and were the only available examples for examination (
BMNH
).
Remarks
. Despite differences in geographical location, these two species described by Gorham (1894) could not be distinguished from each other, hence are treated as a single taxon.
Neaporia viridescens
belongs in a group of very small species having similar male genitalia. It is distinguished from others by a distinct green elytral tint of dorsal surface, frons narrower than eye with widely spaced, coarse punctures, and a smooth, polished dorsal surface.
