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 ).
