Both C. parvulus Blandford and C. uniseptis Schedl were described from unique male specimens, from Las Mercedes, Quetzaltenango, Guatemala and Córdoba, Veracruz, Mexico, respectively. Wood (1982) stated that C. parvulus is “virtually identical with uniseptis ”. I have examined the primary types of C. uniseptis Schedl (NMW), C. parvulus Blandford (BMNH), and a high–resolution photograph of the holotype of C. reburrus Bright (CNCI), previously synonymized with C. uniseptis by Wood (https://cnc.agr.gc.ca/taxonomy/Specimen.php?id=3824). Only a single species is present known from Guatemala, Chiapas, Veracruz, and Jalisco at low to intermediate elevations.

Specimens seen. Guatemala: Quetzaltenango: Las Mercedes, 914 m (BMNH, male, holotype Corthylus parvulus Blandford ); Mexico: Veracruz, Córdoba, A. Fenyes (NMW, male paratype); Veracruz: Uxpanapa, 23-V-1981, ex Heliocarpus appendiculatus (Malvaceae) , A. Equihua M., S-270 (TAMU, 14, CEAM, 5); Chiapas, Palenque Ruins, 22-VI-1969, D.E. Bright (CNCI, photographs female holotype); Jalisco: El Tuito, 640 m, 29-V-1982, T.H. Atkinson & A. Equihua M., S-712 (TAMU, 5, CEAM, 8).
