Characterization. Male: Epicranium black, dorsum of thorax entirely black or with orange narrow antehumeral stripe, dorsum of abdomen mostly orange, with black dorsum of S1, small distal spots on S3–4, distal portion of S6–7, distal 3/4 of S8; pale colors orange, with yellow limited to venter of thorax ( Fig. 15 View FIGURES 13–16 ). Pronotum black with orange spots on middle lobe and lateral margins of hind lobe. Mesepisternum black with orange antehumeral stripe extending along basal 1/2 of sclerite to absent; mesepimeron black with narrow orange humeral stripe along medial 1/2 to distal 3/4 of sclerites to absent, separated from a small distal orange spot; metepisternum black with orange stripe along anterior margin to entirely black; metepimeron black or with ventroposterior margin yellow. Leg dark brown, with margins of coxa, trochanter and base of femur yellowish brown; tibial spurs shorter than twice intervening spaces. Genital ligula lacking lateral lobes, with a straight distal margin, and laterodistal corners projected ventrally and smoothly rounded ( Fig. 85 View FIGURES 85–91 ). Cercus shorter than S10 length, about three fourths as long as paraproct, about as long as wide, medially concave and directed lateroposteriorly, semicircular in dorsal view ( Fig. 111c View FIGURES 109–111 ), with a blunt ventrobasal tooth directed medially and two apical teeth, one on ventrodistal margin and one on mediodorsal margin, both cylindrical, blunt and subequal ( Figs. 111b, c View FIGURES 109–111 ). Paraproct slightly shorter than S10 length, medially concave, and narrowing to half its basal width at midlength ( Fig. 111a View FIGURES 109–111 ). TL 47–48; Hw 21– 24.

Female: As male but dark colors black with metallic green to copper reflections and pale colors yellow; pronotum anterior lobe with a yellow lateral spot; antehumeral stripe narrow and extending along basal 1/3–1/2 of mesepisternum; humeral stripe narrow and extending along distal 1/2–2/3 of mesepimeron; metepisternum black with a medial yellow stripe across entire height; metepimeron yellow with a black spot on anterodorsal margin; coxa, trochanter, and base of femur yellow or brown margined in yellow, remainder of leg brown; S10 black dorsally; pale lateral area of S9 extended dorsally medially to about 2/3 of segment height ( Fig. 39 View FIGURES 37–40 ). Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe directed anteriorly and trilobed, with medial lobe bilobed with sides smoothly convex. Mesostigmal plate upright and semicircular, at medioposterior corner adjacent to a mesepisternal laminar projection directed anterodorsally ( Fig. 61 View FIGURES 60–63 ); no depressions behind mesostigmal plates. TL 41–42; Hw 23.5–24.

Diagnosis. Diagnosed under P. peramans .

Habitat and biology. According to E. González-Soriano (pers. comm.), it inhabits narrow streams, preferably shaded. He has never seen males alone, always in tandem, and suspects that copulation occurs high in the canopy. Females lay eggs on secondary roots and debris deposited along banks of the streams, even distant by a few meters from the water course. Males guard females in tandem in an upright position.

Distribution. Michoacán, Jalisco, Oaxaca, and Guerrero States in Mexico ( Fig. 122 View FIGURES 121–122 ).
