Holotype, ♂, Dominican Republic, Sierra de Bahoruco , 18.2711269N, 71.7249800W, 6.7.2021, J. Pirkl lgt., ( MCSN-VD; GBIFCH00830154 ) (Fig.2) .

Paratypes (5 ♂♂, 9 ♀♀): the same locality as holotype, (7 MCSN-VD ( GBIFCH00830155 - GBIFCH00830161 ), 3 MNHNSD, 3 JPPC, 4 JHAC) .

Description of the holotype

Body. – Body measurements (in mm): TL 2.4, EW 1.5. Dorsal integument brown and dark brown (Fig. 1), setation decumbent, yellow and brown. Ventral integument brown, setation decumbent, yellow.

Head. – Shiny brown and finely punctated, covered with yellow decumbent setation. Palpi light brown. Median frontal ocellus present. Eyes large with hardly visible short microseta. Antennae brown, with yellow setation, consisting of 11 antennomeres, antennal club with 3 antennomeres (Fig. 3). Antennal fossa closed.

Pronotum. – Integument dark brown with yellow and brown setation; brown setation forming two small spots.

Scutellum. – Brown, small, triangular and without punctation and setation.

Elytra. – Integument dark brown in anterior 1/3 with brown and yellow setae, yellow setae forming transverse narrow fasciae, apical part brown with brown and yellow setae, much more densely and finely punctated as the pronotum.

Epipleuron. – Short, dark brown, with some yellow decumbent setation.

Ventral surface. – Metasternum coarsely punctate with yellow decumbent setation. Abdominal visible ventrites shiny, brown, densely and coarsely punctated, with yellow decumbent setation.

Legs. – Tarsi light brown, tibiae brown, femora brown, sparsely covered with very short and fine decumbent, intermixed brown and yellow setae.

Male genitalia. – As in (Fig. 5).

Female. – Externally similar to male. Antennal club smaller than in male.

Variability. – Body measurements (in mm): TL 2.4-3.0, EW 1.5-1.9.

Etymology. – Patronymic, the species is named in honor of its collector, Jiří Pirkl ( Czech Republic).

Differential diagnosis. – The new species is very similar to C. delacruzi Kadej & Háva, 2013 , but differs from it in several ways. Firstly, the structure of the antennae is different, with the terminal antennomere of the antennal club being longer and less broad apically in the new species, whereas in C. delacruzi , it is more broad apically. Additionally, the color of the antennae is different. In C. delacruzi , antennomere I is dark brown, while antennomeres II to XI are light brown. However, in the new species, the antennae are uniformly brown in color. Secondly, the structure of the male genitalia is different, with the parameres being narrower in the new species compared to the very broad parameres in C. delacruzi . Finally, each elytron in the new species has 2 transverse bands. The new species differs from other Dominican species by the characters in the following key.

12. (11) Body black; bridge of parameres as broad as one-fifth of width of penis at its widest part, ratio of length of penis to length of parameres is 1.0:0.85, penis extending above apices of parameres................................................................................................
