Diagnostic description.

Length: 1.85-2.09 mm (avg. 1.95 mm); width: 1.65-1.93 mm (avg. 1.73 mm). This species is very similar and closely related to the preceding, differing principally in the following characters: ground punctation of dorsum slightly coarser; secondary punctures of lateral portion of pronotum gradually increasing in size and density laterad; lateral submarginal pronotal stria usually not reaching anterior corner, abbreviated at front; outer subhumeral stria complete, not interrupted at middle. Male: S8 with only a couple setae at apical corner; basal piece ~ 1/3 length of tegmen; tegmen with sides weakly rounded, slightly wider toward base, more or less flat, with basal ‘notch’ in lateral view, apices subacute, weak medioventral process present in basal 1/3; median lobe ~ 1/2 tegmen length, basal apodemes thin.

Etymology.

The name of this species means starry, referring to the array of pronotal punctures.

Remarks.

This species, like the preceding one, has only been collected through the use of flight interception traps.

Distribution.

This species is known from Amazonian Ecuador, Peru, and Brazil, as well as French Guiana.
