ANTS OF CURAÇAO, species list

Peter Boer

This list is the result of the identification of samples collected between 1930 and 1970 (94%) by H.J. MacGillavry, P. Wagenaar Hummelinck, R.H. Cobben (all in collection Naturalis Biodiversity Center) and 2018 (6%) by R. Schmitz.
All identifications (except the data from literature) are done by the author.

In total almost 2000 ant specimen from Curacao are identified. That results in 59 species.

The most collected ants (species per location) are: first Brachymyrmex minutus, second Paratrechina longicornis, third Wasmannia auropunctata and fourth Dorymyrmex insanus. Paratrechina longicornis and W. auropunctata have a pest status.

*) I could not found any difference between the workers of the taxa Azteca delpini Emery, 1893 (with subspecies antillana and trinidadensis) on the one hand and A. velox Forel, 1899 on the other. Azteca delpini should be more slender, less dimorphic, shinier than A. velox with a little bent thorax and almost no mesosomal grooves. But between all nest samples I have seen from Saba, St Martin, St Eustatius, Bonaire, Aruba, Curacao and some other Caribbean Islands, I see these differences in size, shine, depth of the mesosomal groves (and so the hump of the mesosoma) and even in color. For the time being I leave it at A. delpini.

**) Tapinoma melanocephalum coronatum Forel, 1908 is most likely a species rather than a subspecies, due to differences in pigmentation and DNA (COI gene).

***) Neivamyrmex sp01 resembles N. impudens (a Central American species). The specimen of Curacao have many minute denticles on the apical margin of the mandible in stead of five irregular blunt teeth.

****) All the specimen of Curacao of Camponotus crispulus have the characteristics that would be typical for this species and distinguishes her from the twin species C. blandus. I follow Wild 2007: In my experience, the easiest character to separate C. crispulus from other bicolored blandus-complex species is the unique pattern of pubescense on the gaster. While all species in the complex show some degree of medial convergence in the appressed setae on the gastric terga, in C. crispulus this convergence is extreme, starting on the first gastric tergite well ahead of the posterior margin and continuing to the apex of the gaster almost as a visible line.

*****) The identification of the Pheidole species is based on major workers.

******) In fact this should be Solenopsis globularia-complex. I have the impression that the Curacao specimen belongs to more than one species out of this complex. One of them must be S. globularia.
