Abstract: | One new genus and eight new species of anilline carabids are described from southern Mexico. The new genus, Zapotecanillus
gen. n., is established for Z. oaxacanus (type species) sp. n., Z. nanus
sp. n., Z. iviei
sp. n., Z. ixtlanus
sp. n., Z. montanus
sp. n., and Z. kavanaughi
sp. n. from the Sierra Madre de Oaxaca, Z. pecki
sp. n. from the Sierra Madre del Sur, and Z. longinoi
sp. n. from the Sierra Madre de Chiapas. A taxonomic key for all described species of Zapotecanillus and a cladistic analysis, based on morphological data, are provided. Morphological, behavioral and biogeographical aspects of the speciation in the genus obtained from the resulting cladogram are discussed. |
