Holotype male: "Est. Pitilla, 9km S. Sta. Cecilia, P. N. Guanacaste, Prov. Guana, COSTA RICA. 700 m Ene [January] 1994, C. Moraga, L N 330200_380200 #2563" (INBIO). Paratypes (18): 17: same data as holotype (INBIO, FMNH, AKTC, MSCC); 1: same data as holotype, but iii.1994 (INBIO).

Diagnostic description.

This species is very similar in most characters to Operclipygus mirabilis and is only described to the extent that it differs from it. Length: 1.72-1.75 mm, width: 1.40-1.44 mm; male with lateral submarginal pronotal stria diverging from marginal in anterior two-thirds, ending behind anterior corner, median pair of pronotal gland openings borne on very weak tubercles; pronotal disk not depressed anteriorly around tubercles; lateral submarginal pronotal stria of female situated slightly further from margin, particularly anteriorly, than that of Operclipygus mirabilis . Male genitalia with apical guides of S8 slightly narrower apically than in Operclipygus mirabilis , S9 also slightly narrower and more elongate; aedeagus essentially indistinguishable.

Remarks.

This species and Operclipygus mirabilis are very similar, differing mainly in the exaggeration of the tubercle of the male pronotum, which in Operclipygus pustulifer lacks any surrounding depression (Fig. 9B).

Etymology.

This species’ name refers to the raised gland opening of the male pronotum.
