The original description ( Willmann 1930), based on two specimens from Guatemala is short and lacks information about some morphological structures. Mahunka (1983) found another specimen in Tikal, Guatemala, and provided additional morphological information. I was able to study this specimen. Until further findings in Panama ( Schatz 2006) no other records of C. heterodactylus were known (for erroneous and unproven reports see chapter “Corrections to previously stated distribution data”). I found this species in four different sites in the lowlands of Central and Northwest Panama. Later, additional reports from Panama were given by Basset et al. (2012). Recently, Cultrobates heterodactylus has also been reported from Mexico ( Revelo-Tobar et al. 2022).

The examined specimens from the populations in Panama were morphologically consistent with the specimen from Guatemala and with the descriptions by Willmann (1930) and Mahunka (1983). Some additional morphological features which were not given in detail in previous descriptions are presented here on the basis of specimens from Panama. Comparable speciesspecific differential characters among the species C. heterodactylus , C. ermilovi n. sp. and C. subiasi n. sp. are given in the remark (#1).
