angustus sp. n. - Argentina blackburni (CAMERON, 1886) (Chelonus) - Mexico (introduced) = carinatus (CAMERON, 1881) nec PROVANCHER, 1881 bolsoni sp. n. - Argentina brasiliensis (BRUES, 1912) (Chelonus) - Brazil, Paraguay -szepligetii (VIERECK, 1913) syn. n. buscki (VIERECK, 1912) (Chelonus [Chelonella]) - Trinidad (carinatus CAMERON, 1881 [Chelonus]) = blackburni (CAMERON, 1886) cons trie tus sp. n. - Argentina johni MARSH, 1979 (Chelonus [Microchelonus]) - Colombia kelliae MARSH, 1979 (Chelonus [Microchelonus]) - Costa Rica peruensis SHENEFELT, 1973 - Brazil, Peru =sobrinus (SZÉPLIGETI, 1904) necHALDEMAN, 1849 = szepligetii (VIERECK, 1912) nec DALLA TORRE, 1898 ruficollis (VIERECK, 1912) (Chelonus) - Brazil (sobrinus SZÉPLIGETI, 1904 [Chelonus]) = peruensis SHENEFELT, 1973 subplanus sp. n. - Costa Rica (szepligetii VIERECK, 1913 [Chelonus (Chelonella)] = brasiliensis (BRUES, 1912) topali sp. n. - Argentina townsendi (VIERECK, 1912) (Chelonus [Chelonella]) - Peru Besides the descriptions of the five new species (M. angustus sp. n., M. bolsoni sp. n., M. constrictus sp. n., M. subplanus sp. n., M. topali sp. n.) redescriptions of three known species (M. brasiliensis, M. peruensis, M. townsendi) are also given. Up to the present exclusively the male forms of the Microchelonus species were characterized as having a foramen on the posterior end of their carapace. The size and shape of the foramen is highly variable from a small round or elliptic hole to a large slitlike aperture. In the case of the female forms of the two new Microchelonus species (M. subplanus, M. townsendi) I have surprisingly observed a very small hole on the posterior end of their carapace (cf. Figs 57 and 86). This is the first observation of the foramen on female carapace (in both species the number of the antennomeres is 16 - a generic feature of the female Microchelonus species). Certainly, and likewise to the male forms, the female's carapace foramen is the opening of the pheromon glands which, by their odour, supposedly attract the males in finding the females. Abbreviations applied in the descriptions. - Fore wing: r - first section of the radial vein, 1-Rl = first section of the metacarpal vein, 3-SR and 4-SR = second and third sections of the radial vein. - The features "lateral pair of lobes of scutellum" (see arrows in Fig. 51) and "caudal margin of propodeum" are applied in the sense by McCOMB (1968: 6 and 8, key couplets 17 and 37, respectively).
