AE02D48A10185769A499634BD6F095C3.taxon	description	Description. — (Figs 1 – 6, Tables 1, 2). Male. Body of small size, average length of body 14.22 mm (Table 1); fastigium of vertex rounded or roughly pentagonal in dorsal view with a medial carina, its tip merging smoothly with frontal ridge. Frons slightly oblique; frontal ridge shallowly sulcate above medial ocelli, obliterated below; antennae longer than the combined length of head and pronotum together; eyes protuberant, inter-ocular space slightly wider than antennae scape. Pronotum dorsally crossed by three deep sulci; medial carina very weak or absent. Space between sulci 2 and 3 almost equal to or slightly wider than metazona in length; metazona short, accounting for less than 25 % of the pronotum length (Fig. 3 A). Lateral margins of prozona tuberculate in dorsal view, anterior margin of prozona slightly convex, sometimes slightly notched in the midline. Posterior margin of metazona slightly convex and notched in the midline; prosternal process conical, vertical, pointed. Mesosternal space slightly longer than wide, lobes rounded; metasternal space open, about half of mesosternal space; micropterous. Tegmina minute, lobiform, shorter than, reaching, or barely exceeding middle of metathorax but not reaching mesothorax (Fig. 3 B). Hind femur slender, 5 times longer than wide (Table 1); 6 to 7 external tibial spines, 8 to 9 internal tibial spines (Table 1), external apical spine present; paired internal tibial spurs longer than external spurs. Tympanum wide, oval or rounded. Last abdominal tergite divided, the hind margin with two small lobiform processes forming a minute furcula, the tips separated by 0.3 – 0.35 mm (Fig. 3 D, E), cercus compressed laterally, slightly incurved, slightly shorter than or exceeding the tip of the subgenital plate, with acute apex. Supra-anal plate triangular in dorsal view with acute or slightly rounded apex; proximally in the plate there is a short medial longitudinal groove bounded posteriorly by a curved transverse ridge that extends across the width of the plate (Fig. 3 D). Phallic complex (Figs 4 A, B, 5 A, B) of large size for the genus, ectophallic membrane coarsely stippled and obscures most of the sclerites; epiphallus with large forwardly curved blade-like outer lophi; inner lophi absent (Figs 4 C, D, 5 C, D). Anterior processes of epiphallus well developed, axially large and rounded, ancorae absent (Figs 4 C, D, 5 C, D). Oval sclerites large with pronounced pointed tubercles on their ventral surfaces (Fig. 4 F); valvular plate foliose, showing large lobes that dorsally join the cingulum by a well-prolonged arch. Cingular apodemes dorsally blade-like, incurved (Fig. 5 E); cingular ramus laterally large, prolonged and rounded (Fig. 5 F). Endophallic apodemes dorsally slender, laterally large, spatula shaped, with robust, long and pointed gonopore processes; endophallic process terminates on the ventral aedeagal sclerite which forms a part of the ventral aedeagal valve (Fig. 5 G). Female. In general, similar to the male. Female particularities: body of small to medium size, average L = 18.11 mm (Table 1). Lateral margins of prozona less tuberculate in dorsal view; last abdominal tergite short, divided, but the hind margin without a furcula. Cercus robust, very slightly compressed laterally almost conical, straight or very slightly excurved, equaling or slightly exceeding the supra-anal plate, with acute apex; supra-anal plate triangular in dorsal view, elongated, lingulate, with rounded apex. Ovipositor valves smooth, slender, long, with rounded apex; subgenital plate ventrally conical, distally with a medial groove bounded laterally by two inflated ridges, not projecting posteriorly beyond the posterior edge of the plate. Egg-guide slender, rod-like, long, about half of the ventral ovipositor valves in length (Fig. 3 C). Dorsally, subgenital plate smoothly triangular, terminated by a straight and pointed egg guide at the tip; a pair of large sclerotized columellae that are prolonged by a pair of less sclerotized stripes (Fig. 6 A). Bursa copulatrix large, dorsally with a longitudinal groove separating the bursa into two somewhat distinct lobes (Fig. 6 B, C), spermathecal duct long; spermatheca with a hooked terminal ampulla and a developed lateral diverticulum (Fig. 6 B, D).	en	Oumarou-Ngoute, Charly, Song, Hojun, Mariño-Pérez, Ricardo, Woo, Brandon M., Linde, Jackson, Rowell, C.

AE02D48A10185769A499634BD6F095C3.taxon	diagnosis	Diagnosis. — Of small size relative to the rest of the genus, with average L = 14.22 mm in male and L = 18.11 mm in female. Body predominantly black in male with wide yellow patches in pronotum, female genae green with a red or yellow stripe, narrow below eyes, widened toward the pronotal lobes, and continuous in two patches in the pronotal lobes, abdominal segments green (Table 2); different to P. apicalis (Fig. 7). Metazona short, accounting for less than 25 % of the pronotum length; tegmina minute, lobiform, shorter than, reaching, or barely exceeding the middle of the metathorax but not reaching the mesothorax. Furcula small, lobiform, the tips separated by 0.3 – 0.35 mm. Oval sclerites of epiphallus large, with pronounced pointed tubercles on their ventral surfaces; endophallic apodemes dorsally slender, laterally large, spatula shaped, with robust, long, and pointed gonopore processes; pronounced flexure (Table 2).	en	Oumarou-Ngoute, Charly, Song, Hojun, Mariño-Pérez, Ricardo, Woo, Brandon M., Linde, Jackson, Rowell, C.
