Figures 19–24. Figures for use with amended key above. 19) Crioprosopus nieti, female, La Perla de San Martin, Veracruz, MX, with lateral tubercles on sides of pronotal disc obtuse. 20) C. wappesi, male, Baja Verapaz, Guatemala, with lateral tubercles on sides ofvpronotal disc obtuse. 21) C. servillei, malev (i.e., C. divisus), La Paz, Honduras, v with sides of pronotal disc broadly angulate; with pronotum inflated. 22) C. nieti, male, 14–15 km W Sontecomapan, Veracruz, MX with transverse orange band on elytra, leg and antennae black. 23) C. wappesi without transverse band on elytra, head, antennae and leg reddish brown. 24) C. servillei, elytra flavo-testaceous, finely punctate, and disc with dark spots on anterior margin adjacent to scutellum, transverse maculae in middle, and irregular macula apically.

Figures 1–9. Characteristics of the head of Crioprosopus, and dorsal and lateral view of Crioprosopus baldwini, sp. nov. 1–3) C. baldwini, paratype, Boquete, Panama showing characters of the head of Crioprosopus as described by Linsley (1962), i.e., “front large, perpendicular, abruptly separated from anteocular space.” 1) Gena large, quadrate well separated from lower eye lobe. 2: 2a) Apex of mandibles acute, simple; 2b) Dorsal anterior margins of genae ridged. 3: 3a) Front perpendicular to vertex and recessed or indented between the “anteocular space” (i.e., between the dorsal anterior margin of gena) so the front is “pushed back in towards the eye.” 4: 4a) Prosternum with intercoxal process arcuate at apex. 5) Elytra distinctly marginated laterally. 6–7) Dorsal and lateral view of C. baldwini, holotype, female, Puntarenas, Costa Rica. 8–9) Dorsal and lateral view of C. baldwini, paratype, female, Boquete, Chiriquí Prov., Panama.
