Abstract
This is a revision of the species of the genus Chilicola found in the South American Andes, Peru
to Venezuela, above elevations of 1000 m. In addition to the four previously described species known from this
area, 23 new species are recognized and described. They fall into three groups: (1) The C. ashmeadi group of the
subgenus Anoediscelis, for C. ashmeadi (Crawford) and the following new species: C. colombiana, mistica,
venezuelana, wygodzinskyi, xanthostoma, xanthognatha, cooperi, pedunculata; (2) Subgenus Hylaeosoma for C
aequatoriensis Benoist and the following new species: C. involuta, umbonata, canei, belli, smithpardoi; (3) The new
subgenus Oroediscelis (type species, Chilicola styliventris) for C. styliventris Friese, quitensis Benoist, and the
following new species: C. espeleticola, brooksi, benoistiana, cuzcoensis, bigibbosa, maculipes, transversaria, gibbosa,
brzoskai, simplex. Phylogenetic analyses are presented for the subgenera of Chilicola and for the species of the
subgenus Oroediscelis. Aspects of nesting biology are presented for C. espeleticola and C. styliventris.
