Comment | Synonymy mostly that of Dixon (1973). BAUER & GÜNTHER 1994 list Bachia alleni trinitatis as valid combination. Thomas (1965) considered B. trinitatis to be a subspecies of B. alleni. Later, Donoso-Barros (1968) considered B. marcelae to be a subspecies of B. lineata, retaining B. heteropa and B. alleni as separate species. However, Dixon (1973) synonymized B. marcelae with B. heteropa. However, John et al. 2012 recognized marcelae as valid. The name Chalcides heteropus was not used by Wiegmann as occasionally cited, but by Lichtenstein and Martens 1856 (15 years are Wiegmann’s death) who are the original describers. See Gutsche 2016: 169 for details. Subspecies: Intermediate specimens between B. h. heteropa and B. h. trinitatis are known from eastern Venezuela but intermediates between B. h. lineata and B. h. heteropa are unknown although both subspecies have been recorded from nearby areas (B. h. heteropa from la Guaira, Vargas State and B. h. lineata from Distrito Federal, Caracas) [RIVAS et al. 2012]. Bachia heteropa alleni (BARBOUR 1914) has been elevated to full species status. Type species: Chalcides heteropus Lichtenstein 1856 is the type species of the genus Sesquipes Cope 1896:466 (fide Dixon 1973: 14). Distribution: Not on Tobago (Murphy et al. 2019). NCBI taxon ID: 371684 [trinitatis] |
