Characterization. Male: Epicranium black, black stripes on thorax, dorsum of S1, S3–10 brown to black; pale colors bright yellow to pale yellow ventrally ( Fig. 19 View FIGURES17–20 ). Pronotum anterior lobe black with medial and lateral yellow spots, middle lobe with dorsum yellow, and posterior lobe entirely yellow. Mesepisternum bright yellow with middorsal carina black and a narrow black stripe along distal 1/4 of mesepisternal-mesepimeral suture; mesepimeron yellow anteriorly and black posteriorly; metepisternum yellow with black along posterior margin; metepimeron entirely pale bright to pale yellow. Leg pale yellow with tip of femur, tibia, and tarsi dark brown, sometimes with two diffuse brownish rings subbasally and subapically on each femur and tibia; tibial spurs shorter than twice intervening spaces. Genital ligula lacking lateral lobes and with a slightly concave distal margin, with lateral margins of distal segment spiculate and laterodistal corners not projected ventrally ( Fig. 89 View FIGURES 85–91 ). Cercus shorter than S10 length, about as long as paraproct, about as long as wide, with a depression on external dorsolateral surface and a longitudinal split along ventrodistal portion, dorsal margin with a distal concavity and ventral margin slightly convex in lateral view ( Fig. 115a View FIGURES 115–118 ), with medial surface concave and with a small blunt ventrobasal tooth and two apical dorso-ventral ridges, one on distal margin and one on medial surface, visible in mediodorsal view ( Fig. 115b View FIGURES 115–118 ), with tips appearing as pointed teeth in dorsal view ( Fig. 115c View FIGURES 115–118 ). Paraproct shorter than S10 length, at midlength narrowing to half its basal width and ending in a triangular tip ( Fig. 115 View FIGURES 115–118 ). TL 35; Hw 15.5–17.

Female: As male but middle lobe of pronotum with yellow restricted to a lateral band, posterior lobe black with yellow medial and lateral spots; mesepisternum black with yellow antehumeral stripe along basal 2/3, mesepimeron black with a yellow stripe along medial 3/4 of mesepisternal metepimeral suture separated from a dorsal yellow spot, and all abdominal segments black dorsally; pale lateral area of S9 extended medially to about 1/ 3 of segment height ( Fig. 43 View FIGURES 41–44 ). Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe entire, with sides straight converging to a smoothly convex tip, directed dorsally. Mesostigmal plate approximately triangular and flat with a central shallow concavity, anterior margin carinate and straight, and posteromedial corner merging into a low tubercle on mesepisternum ( Fig. 65 View FIGURES 64–70 ). TL 31.5; Hw 17.25–17.75.

Diagnosis. Among the species with male paraproct no longer than S10 length, P. sulfurata shares male cercus approximately quadrangular, about as long as wide, with a ventrodistal longitudinal split and depression on external dorsolateral surface, concave medial surface, and two short apical teeth in dorsal view ( Figs. 98 View FIGURES 97–99 ; 99; 105; 115), and genital ligula distal segment with lateral margins spiculate ( Figs. 72 View FIGURES 71–78 ; 73; 79; 89) with P. amatoria , P. aurantiaca , and P. cupida . It can be distinguished from them by its bright yellow color and by the two apical dorsoventral ridges on medial surface of male cercus ( Fig. 115b View FIGURES 115–118 ), which are represented by two dorsal teeth in the other three species ( Figs. 98b View FIGURES 97–99 ; 99b; 105b). Female mesostigmal plate triangular with posteromedial corner merging into a low mesepisternal tubercle is unique for this species ( Fig. 65 View FIGURES 64–70 ).

Habitat and biology. Shallow and heavily vegetated small streams.

Distribution. Nicaragua and Costa Rica ( Fig. 123 View FIGURES 123–124 ). Assessed as Least Concern by IUCN ( Paulson 2009g).
