Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.

Biology

Ward (1992) - One does not get the impression that the West Indies are a haven for relicts in the genus Pseudomyrmex. One exception is provided by the endemic Hispaniolan species, P. haytianus. This species is not a member of any of the major species groups and is one of the few extant species of Pseudomyrmex which shows any obvious affinities with the Dominican amber fauna.

Description

Worker

Kempf (1961) - Diagnostico baseado em tres exemplares sintipos de var. affinis de Diquini, Haiti, e num exemplar da var. torquata de S . Jose de. las Matas, Rep, Dominicana. Comprimento total 5,5-5,9 m m; comprimento da capsula cefalica 1,11-1,16 mm; largura da capsula cefalica 0,98-1,03 mm; com primento do torax 1,50-1,64 mm. indices : cefalico 89; oculocefalico 48-52; toracico 34-36; cefalo-toracico 71-74. — Cabeca mais larga e olhos maiores (cf. indices!). Olhos situados aproximad amente no meio dos lados da cabeca. Torax mais robusto, com sulco meso-epinotal mais nitidamente impresso e marcado por sutura. Face basal do epinoto mais curta, pouco mais comprida que a face declive. Peciolo como em championi, mas sem d ente antero-ventral. Pubescencia urn pouco mais pronunciada e forte.

A operaria de haytianus tipico, segundo a descricao de Forel, distingue-se por antenas e tarsos de amarelo-vivo, patas de marron-preto, torax de vermelho vivo, com mancha castanha no mesonoto e na face declive do epinoto. Cabeca escura com mancha avermelhada de cada lado, atras dos olhos.

Kempf (1961) - Desconhece-se esta casta de haytianus tipico. Wheeler e Mann descreveram sumariamente a femea da "var. affinis", indicando apenas o tamanho de 8 mm, e a cor que coincide com a da operaria. Tenho uma femea, procedente de Barahona, Rep. Dominicana (P. J. Darlington, leg.), que corresponde a "var. torquato", ainda nao descrita. E is seus caracteres:

Comprimento total 8,2 mm; comprimento da capsula cefalica 1,57 mm; largura da capsula cefalica 1,09 mm; comprimento do torax 2,34 mm. — indices: cefalico 69; oculo-cefalico 41. — Cor como n a operari a da var. torquata. Cabeca mais comprida que em championi, retangular com os lados retos e a borda occipital levemente chanfrada. Lobo mediano do clipeo com borda triangular, de ponta romba. Sulco frontal ate 2/3 do comprimento dos olhos. Femures dianteiros conspicuamente engrossados. Peciolo como em championi, mas sem dente antero-ventral.
