Head punctures large, separated by less than a diameter; pronotal punctures as large as on head, separated by a less than to twice a diameter; elytral punctures as large as on pronotum separated by less than to 3 times a diameter; prosternum with small punctures separated by less than a diameter; mesosternum with punctures larger than on prosternum, separated by about a diameter; metasternum with punctures as large as on mesosternum, separated by less than to twice a diameter in median 1/3, absent in lateral 1/3; abdominal ventrites 1, 2 with small punctures separated by about 1-3 times a diameter; ventrites 3–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons parallel sided, slightly wider than eye, clypeal apex widely emarginate, lateral angle abruptly curved (
Fig. 101
); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina straight, extended 1/2 distance from apex to base of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 3/4 distance to rear margin of ventrite. Genitalia with penis guide long, basal lobe as long as paramere, sides nearly parallel in basal 2/3, gradually narrowed to rounded apex in apical 1/3; paramere slender, curved, apex rounded (
Fig. 102, 103
); penis long, slender, apex extremely attenuate, attenuate portion at least as long as 1/2 length of penis; basal capsule sinuate, inner arm short, narrow, weakly bent, outer arm short, curved, apex V-shaped, rounded (

Remarks.
The male genitalia with basal lobe are quite different from those of
P

nadine
, also a
Trinidad
species. The mostly yellow male pronota also are of value in recognition as is the narrow, reddish, lateral elytral margin.
