Diagnosis. Recognized by the following set of features: dorsum brown with yellow areas ( Fig. 4e ); antennal segment II with very narrow, white annulation apically ( Fig. 4e ); lateral portion of pronotum broadly yellow ( Fig. 4e ); scutellum with very weakly convex, narrow medial, longitudinal swelling ( Fig. 4e ); hemelytron brown with yellow stripes ( Fig. 4e ).

Redescription. Male. COLORATION ( Fig. 4e ). Dorsum dark brown with yellow areas. Head. Fuscous yellow; antennal segment I dark yellow brown to dark brown, narrowly white basally; segment II dark brown to fuscous with whitish apex; segments III and IV fuscous; labium dark brown, tinged with yellow. Thorax. Pronotum. Dark brown with broad yellow tinge laterally. Mesoscutum and scutellum. Dark brown with two yellow patches, each situated baso-laterally. Thoracic pleura. Proepisternum and proepimeron yellow; ventral half of proepisternum and narrow anteroventral portion of proepimeron dark castaneous; remaining pleura dark brown; metathoracic scent gland evaporative areas yellow. Hemelytron. Dark brown to fuscous with large yellow areas; embolium yellow; R+M vein with yellow, longitudinal patch medially and with smaller round patch subapically; endocorium with indistinct, longitudinal yellow tinge; anal vein yellow along entire its length; membrane fuscous, weakly tinged with yellow medially. Legs. Procoxa dark castaneous; meso- and metacoxae yellow, weakly tinged with red; femora dark yellow brown; meso- and metafemora with yellow patch near apex; meso- and metatibiae brown at basal half, dark brown at apical one-fourth, with broad, yellow band near apex; meso- and metatarsi dark brown. Abdomen. Dark castaneous to dark red tinged with yellow. TEXTURE AND VESTITURE ( Fig. 4e ). Thorax. Mesoscutum and scutellum. Covered with long, erect setae and with shorter, semi-recumbent setae. Hemelytron. Covered with semi-recumbent and erect setae. STRUCTURE ( Fig. 4e ). Thorax. Pronotum. Posterior lobe flat. Mesoscutum and scutellum. Scutellum with weakly convex, narrow longitudinal, medial swelling.

Female. Like male in coloration, structure, texture, and vestiture.

Measurements. ♂ / ♀. Body. Length: 5.6/5.6, width 1.75/2.0. Head. Length: 0.45/0.5, width: 1.1/1.1, interocular distance 0.45/0.45. Antenna (female, missing in male). Length of segment I: 0.65, II: 2.5, III: 2.75, IV: (missing). Labium (male, immeasurable in female). Length of segment I: 0.62, II: 0.60, III: 0.60, IV: 0.40. Pronotum. Length 0.8/0.75, width of anterior margin: 0.95/0.85, length of lateral margin: 0.9/0.85, width of posterior margin: 1.75/1.8.

Biology. Unknown.

Distribution. Peru (Cuzco).

Remarks. This species possesses a metathoracic ostiolar canal that is weakly raised above evaporative areas, the ostiolar peritreme is oval and moderately raised (as in Fig. 10d ), and the tarsus with tarsomere I is two times shorter than II and III combined (as in Figs 11j, o ). These characters do not fit the diagnosis of Cylapus where the ostiolar canal is strongly raised, the peritreme is arcuate and sharply pointed ( Fig. 10c ) and tarsomere I is as long or longer than II and III tarsomeres combined. The combination of these characters is found in the genus Peltidocylapus as defined in the present paper, and C. festinabundus is here transferred from Cylapus to Peltidocylapus .

P. festinabundus is like P. cerbereus , P. nubilus , and P. picatus in sharing indistinct, weakly convex longitudinal medial swelling on scutellum. It can be distinguished by the yellow, large patch on lateral portion of pronotum.

Type material. Holotype ♂: Peru (Callanga) ( NHRS, not examined).

Additional examined material. ♀ and ♂: Hoch Peru ( NHRS) .
