Panameric, El Zamorano, 9 July 1990, Habitat y compartamiento En hojas oc Roble (1 female, ACMT); Danli, 25 July 1978, J.V. Mankins, #79-1841 (1 female, USNM); La Paz, 21 July 1978, J.V. Mankins, #79-1840 (1 male, USNM).
Note. The female Crioprosopus servillei can be distinguished from other non-metallic species by the following characteristics: (1) glabrous pronotum; (2) elytra which are finely punctate with two vague costae on each elytron; and (3) by the pattern of the dark markings around the humerus and scutellum. The corrugated dark marking in the middle of the elytra widens towards the outer edge. Both C. amoenus Jordan and C. chiriquiensis sp. nov. also have the glabrous pronotum similar to C. servillei; however, the elytra are glabrous and the three transverse, dark fasciae are wider and continuous across the elytra. Antennal segments 3–5 of C. servillei lacks the dorsal canaliculation found in C. amoenus and C. chiriquiensis. According to Audinet-Serville (1834:53), the etymology of the genus Crioprosopus based on C. servillei female is, “Κρος, Bélier (Aries or Ram), πρόσωπον, face.”
Crioprosopus divisus Bates, 1885:320 (Type locality: Mexico, Veracruz: Tuxpan); Aurivillius, 1912:457 (cat.); Blackwelder, 1946:588 (cat.); Chemsak, Linsley & Noguera, 1992:80 (cat.); Monné, 1994:38 (cat.); Monné & Giesbert, 1993:141 (cat.); Noguera & Chemsak, 1996:402 (dist.); Monné & Hovore, 2006:140 (cat.); Monné, 2013:731 (cat.). Distribution: Mexico (Veracruz), Honduras. In this review, Crioprosopus divisus (Figs. 134–135) is the male of C. servillei. In C. divisus (male) and C. servillei (female), there are similarities in the placement of elytral maculae around the scutellum and humeri (Figs. 83, 88), the transverse maculae at the middle, and the irregular apical band. In the male, the maculae are smaller or less extensive and faint compared to the female. Other similar features in both sexes include: (1) triangular scutellum (Figs. 84, 89); (2) elytra that are finely punctate with two vague costae on each elytron (Figs. 85, 90); and (3) wrinkles on the elytral disc near apex of scutellum (Figs. 86, 91). Currently, a specimen of C. saundersii White has not been examined for comparison; however, this species is also very likely to be conspecific to C. servillei where the dark maculations on the elytral and pronotal disc are more extensive. The C. divisus specimen described above was found in the USNM collection labeled Crioprosopus saundersii White as determined by J.A. Chemsak along with another female (C. servillei) specimen, both from Honduras, placed side by side in the same unit tray. Chemsak’s determination as C. saundersii, instead of C. divisus (or servillei), is likely to be based on the known distribution of Crioprosopus at this time where saundersii was the only non-metallic species found in Honduras.
There are some variations in the maculation of the elytra, and the pronotal disc of divisus as shown in photo (Bezark, 2014, id: 6135). According to the description of the holotype male C. divisus by Bates (1885), the elytra are flavo-testaceous, and on both sides there are four black maculae, first near the base adjacent to the scutellum, two transversely behind the middle (a smaller macula on the outside and adjacent to a larger one near the suture), and at the apex. Bates further notes that the surface of the thoracic disc is linearly impressed with five small, discoid maculations towards the posterior margins, which are polished. The holotype male is slightly smaller in length (i.e., 13 lines or 27.5 mm) than the example described above.
