Etymology. The specific epithet refers to the country of occurrence, Costa Rica.

Diagnosis. This species differs from other congeners by the following combination of characters: pronotum and elytra different in color; pronotum with dark reddish brown longitudinal maculation at middle, possessing two vague lateral markings on each side of the maculation; antennal segment XI with one oval antennal sensilla; pro- and mesotarsal segments II and III of males moderately dilated; apical margin of tegmen truncate, shallowly emarginate at middle in ventral view; median lobe subparallel-sided at basal 1/3, then moderately converging anteriorly in ventral view; median lobe in ventral view subparallel-sided at basal 1/3, then moderately converging anteriorly; apical margin of median lobe widely rounded in ventral view; apex of long, slender gonocoxites deeply incised, somewhat swollen at apices.

Similar Species. This new species is similar to C. maculatus   , in having one antennal sensilla and similar shape of body maculation and male genitalia, but can be distinguished by the following combination of characters: abdominal tergite VII and venter without maculation, apex of ovipositor more deeply incised and swollen apically. It is also similar to C. monticola   , in having similar body maculation and shape of male genitalia, but can be distinguished by the following combination of characters: antennal segment XI with one oval antennal sensilla; gonocoxites somewhat swollen at apices.

Description. Length 1.92–2.32 (2.10) mm, width 1.47–1.80 (1.65) mm, depth 0.93–1.10 (1.00) mm (n = 5). Male. Body ( Fig. 1J View Fig ) oval; dorsal disc of head and antennal club dark brown except apical areas of head and club paler; antennal segments I–VIII and venter reddish yellow; pronotum reddish yellow, with dark brown longitudinal maculation at midline, possessing 2 vague lateral markings; scutellum and elytra reddish brown. Head: Dorsal disc possessing sparse, minute punctures; interspaces reticulate. Labrum feebly notched at middle. Antenna ( Fig. 7C View Fig ) with club long and large, ACL/ASI-VIII = 0.74 (n = 1); antennal segment XI with an oval antennal sensilla; approximate ratio of each segment (n = 1) 3.13: 2.10: 2.05: 1.57: 1.71: 1.15: 1.13: 1.00: 3.23: 2.86: 4.21. Pronotum: 2.99–3.48 (3.28) times as wide as long (n = 5); disc possessing sparse, minute punctures; interspaces reticulate. Scutellum: Disc possessing few minute punctures; interspaces reticulate. Elytra: 0.98–1.06 (1.02) times as long as wide (n = 5), 3.61–4.44 (4.00) times as long as pronotum (n = 5), widest at basal 1/3; each elytron with 9 regular rows of deep, large punctures; interstices without punctures or with few minute punctures. Venter: Prosternum feebly convex along midline. Metaventrite strongly convex. Abdominal sternite III without subcoxal lines. Legs: Slender; pro- and mesotarsal segments I to III moderately dilated; tarsal claws simple. Genitalia: Tegmen ( Fig. 7A View Fig ) constricted at middle, then moderately convergent apically in ventral view; TL/TW = 1.71 (n = 1); apical and lateral margins of tegmen strongly undulating in ventral view; apical margin of tegmen truncate, shallowly emarginate at middle in ventral view; median lobe ( Fig. 7B View Fig ) subparallelsided at basal 1/3, then moderately converging anteriorly in ventral view; apical margin of median lobe widely rounded; sclerites of internal sac as in Fig. 7B View Fig . Female. Pro- and mesotarsal segments I–III more weakly dilated than those of males. Ovipositor ( Fig. 7D View Fig ) with long, slender gonocoxites deeply incised at apex and slightly swollen.

Distribution. Costa Rica (San José and Cartago) (Map 3).
