Peltidocylapus cerbereus: Carvalho & Fontes 1968: 276 (list); Carvalho & Dolling 1976: 794 (discussion of type); Schuh, 1995: 32 (catalog), 2002–2013 (online catalog); Gorczyca 2006a: 18 (catalog).

Diagnosis. Recognized by the following set of features: overall dorsal coloration brown ( Fig. 4c View FIGURE 4 ); antennal segment II with apical, white annulation relatively broad, as wide as half of interocular distance ( Fig. 4c View FIGURE 4 ); scutellum with weakly developed medial, longitudinal swelling ( Fig. 4c View FIGURE 4 ); basolateral angle of scutellum with distinct, yellow patch ( Fig. 4c View FIGURE 4 ); hemelytron brown, clavus with short yellow stripe subapically ( Fig. 4c View FIGURE 4 ).

Redescription. Female. COLORATION ( Fig. 4c View FIGURE 4 , 7e View FIGURE 7 ). Dorsum light castaneous with dark brown with and yellow areas. Head. Dark yellow brown; antennal segment I dark castaneous, narrowly yellow basally; segments II–IV dark brown; segment II yellow at basal one fourth and at extreme apex; labium dark yellow brown. Thorax. Pronotum. Dark brown. Mesoscutum and scutellum. Dark brown; scutellum with two yellow patches, each situated basolaterally and with small, yellow spot apically. Thoracic pleura. Dark brown; proepimeron with narrow, yellow stripe along posterior and ventral margin; metathoracic scent gland evaporative areas yellow. Hemelytron. Mostly light castaneous; inner portion of corium dark yellow; clavus with short, yellow stripe near apex, bordering claval suture; membrane grey, weakly tinged with yellow. Legs. Procoxa dark castaneous, tinged with dark yellow and red; meso- and metacoxae yellow, tinged with red; femora brown; pro- and mesofemora tinged with yellow; metafemur with broad yellow band basally and narrower yellow band near apex; tibiae and tarsi dark yellow brown. Abdomen. Dark castaneous tinged with red and yellow. TEXTURE AND VESTITURE. Head. Covered with fine, sparse, semirecumbent and erect setae; antennal segment I shiny, covered with a few fine, erect setae; segment II very sparsely covered with semi-recumbent fine, short setae; segments III and IV with relatively dense, semi-recumbent setae; labium with sparse, relatively long, fine, semi-recumbent vestiture. Thorax. Pronotum. Covered with short, fine, recumbent setae. Mesoscutum and scutellum. Covered with short, fine, recumbent, sparse setae. Thoracic pleura. Covered with relatively dense setae. Hemelytron. Covered with short, fine, recumbent, sparse setae. STRUCTURE ( Fig. 4c View FIGURE 4 , 7e View FIGURE 7 ). Head. Antennal segment I weakly thickened medially; segment II thin, about two times thinner than segment I, almost cylindrical, weakly broadened apically ( Fig. 4c View FIGURE 4 ). Thorax. Pronotum. Posterior lobe with indistinct rib medially ( Fig 4c View FIGURE 4 ). Scutellum. With weakly convex, narrow, longitudinal medial swelling ( Fig 4c View FIGURE 4 ).

Measurements. Lectotype ♀: Body. Length: 4.5, width 1.6. Head. Length: 0.42, width: 0.95, interocular distance 0.3. Antenna. Length of segment I: 0.40, II: 1.85, III: 2.20, IV: 3.00. Labium. Length of segment I: 0.70, II: 0.75, III: 0.62, IV: 0.32. Pronotum. Length: 0.60, width of anterior margin: 0.66, length of lateral margin: 0.63, width of posterior margin: 1.40.

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

Distribution. Distribution: Panama (Chiriquí).

Remarks. Most like P. nubilus in sharing relatively small body (smaller than 5.0 mm) and corium uniformly colored ( Figs 4c View FIGURE 4 , 5a View FIGURE 5 ). P. cerbereus can be distinguished by the presence of pale patches on each basolateral angle of scutellum and white annulation on apex of antennal segment II.

Type material. Lectotype ♀: Lectotype (round label); Bugaba, Panama, Champion; B.C.A Hem. I, Cylapus erebeus (BMNH) .
