Heriades (Neotrypetes) tayrona Gonzalez & Griswold, 2011

( Figures 1–14 )

Diagnosis. This species can be easily recognized by the following combination of characters: female clypeus with a narrow (about two-fifths of basal width of clypeus), shallow median emargination on the distal margin delimited laterally by a small tubercle; ocelli very small in both sexes, slightly larger (1.2–1.4 times) than the diameter of punctures in the interocellar area; and basal metasomal terga uniformly punctate, with punctures smaller than those on scutum and separated by a puncture width or less. Male sterna five and six are similar to those in H. currani ; it can be distinguished by the larger ocelli.

Description (Male). As in the female (cf. Gonzalez and Griswold 2011), except: Body length, 5.2 mm; forewing length, 3.5 mm. Compound eyes about twice as long as broad, two times wider than gena in profile; intertorular distance 1.8 times torulorbital distance; interocellar distance 4.3 times median ocellar diameter, about as long as ocelloccipital distance, slightly longer than ocellocular distance; labrum without small median tubercle basally; mandible with condylar ridge not abruptly angled, outer ridge and acetabular carina not abruptly ending in tubercle; clypeus 1.6 times broader than long, distal margin slightly concave, without shallow median emargination delimited by small tubercle; scape 1.9 times longer than wide, 0.6 times torulocellar distance; pedicel about as long as broad, slightly longer than first flagellomere; first flagellomere 1.4 times broader than long, about half length of second; second flagellomere 1.3 times longer than broad, about as long as third. Sixth and seventh terga, second to eighth sterna, and genital capsule as in figures 4–14.

Integumental sculpture as in female except for first metasomal sternum and second laterally with punctures large, as those on scutum; median portion of second sternum with much smaller, denser punctures.

Pubescence in general as in female, except for clypeus and supraclypeal area densely covered by short, minutelybranched hairs obscuring integument.
