Diagnosis. Recognized by the following set of features: dorsum dark brown (Fig. 6a); antennal segment II with relatively broad, apical, white annulation that is as wide as half of interocular distance (Fig. 6a); posterior lobe of pronotum with distinct swelling medially (Fig. 6a); scutellum distinctly convex, with longitudinal swelling medially (Fig. 6a); anal vein with short, yellow stripe subapically (Fig. 6a); endosoma membranous; distal sclerotized part of ductus seminis (dss) short, rectangular (Figs 14a, b); ventro-apical margin of ductus seminis inside endosoma with deep incision (Fig. 14b); left paramere apical process with short basolateral outgrowth (Figs 14c, d).

Redescription. Female. COLORATION (Fig. 6a). Dorsum dark brown. Head. Dark brown with dark yellow areas medially and laterally; antenna dark brown; antennal segment II with relatively broad, apical, white annulation that is as wide as half of interocular distance; labium dark brown. Thorax. Pronotum, mesoscutum, scutellum and hemelytron. Dark brown; anal vein with short, yellow stripe subapically. Thoracic pleura. Dark brown; metathoracic scent gland evaporative areas tinged with dark yellow posteriorly. Legs. Pro– and mesocoxae dark brown; metacoxa yellow, dark brown basally; femora dark castaneous, with yellow annulation subapically; metafemur with broad, yellow annulation basally; tibiae dark castaneous; tarsi brown, tinged with dark yellow. Abdomen. Black, tinged with dark yellow. TEXTURE AND VESTITURE (Fig. 6a). Thorax. Mesoscutum, scutellum, and hemelytron. Covered with short, fine, dense, recumbent setae. STRUCTURE (Fig. 6a). Thorax. Pronotum. Posterior lobe with distinct swelling medially. Scutellum. With strongly convex, broad longitudinal swelling medially. Hemelytron. Surface between R+M vein and medial fracture rugose. Abdomen. Genitalia. Endosoma membranous (Figs 14a, b); distal sclerotized part of ductus seminis (dss) short, rectangular, with transparent portion dorsally (Figs 14a, b); ventro-apical margin of ductus seminis inside endosoma with deep incision (Fig. 14b); left paramere C-shaped, apical process with short process basolaterally (Figs 14c, d); right paramere sickle-shaped (Figs 14e).

Male. Like female in color, structure, texture, and vestiture.

Measurements. ♂ / ♀, lecotype measurements second. Body. Length: 7.00/6.40, width 2.00/2.3. Head. Length: 0.51/0.50, width: 1.1/1.2, interocular distance 0.40/0.43. Antenna. Length of segment I: 0.73/0.62, II: 2.6/2.75, III: 2.8/3.10, IV: 3.15/3.5. Labium (immeasurable in holotype). Length of segment I: 0.70, II: 0.87, III: 0.85, IV: 0.35. Pronotum. Length: 1.00/1.00, width of anterior margin: 1.10/1.10, length of lateral margin: 1.05/1.00, width of posterior margin: 2.20/2.20.

Biology. Unknown, collected on fallen trees covered with black fungi (Distant 1883).

Distribution. Costa Rica (Cartago), Guatemala (Senahu).

Remarks. Most like P. scutellaris in sharing the clavus having a short, yellow stripe apically (Figs 6a, b), the distal portion of ductus seminis inside endosoma (dss) short, not caliciform with ventro-apical margin concave in the middle (Figs 14a, b, f, h), and the left paramere apical process lateral outgrowth short (Figs 14c, d, i, j). It can be distinguished by the presence of deeper incision on ventro-apical margin of the dss (Fig. 14b).
