Strumigenys dolichognatha Weber, 1934 Specimen Labels

Known from a few collections, including forest litter and bromeliad samples.

Identification

Bolton (2000) - A member of the cordovensis complex in the Strumigenys mandibularis-group. The relative position of the distal preapical mandibular dentition is diagnostic of dolichognatha within the cordovensis-complex.

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

DaRocha et al. (2015) studied the diversity of ants found in bromeliads of a single large tree of Erythrina, a common cocoa shade tree, at an agricultural research center in Ilhéus, Brazil. Forty-seven species of ants were found in 36 of 52 the bromeliads examined. Bromeliads with suspended soil and those that were larger had higher ant diversity. Strumigenys dolichognatha was found in a single bromeliad and was associated with the suspended soil and litter of the plant.

Description

Worker

Bolton (2000) - TL 3.7-4.8, HL 0.80-1.07, HW 0.60-0.87, CI 75-81, ML 0.96-1.34, MI 118-125, SL 0.62-0.90, SI 103-112, PW 0.32-0.45, AL 0.72-0.92 (6 measured). Characters of cordovensis complex. Distal preapical tooth of mandible closer to proximal preapical tooth than to apicodorsal tooth. In full-face view outer margins of mandibles strongly divergent anteriorly and sides of head behind eyes divergent posteriorly. Standing hairs on head and alitrunk sparse, stiff and simple, truncated or weakly expanded apically: one in apicoscrobal position; a pair on vertex close to occipital margin; one at pronotal humerus; absent from mesonotum. Petiole and postpetiole with elongate fine curved hairs. First gastral tergite with a few flagellate hairs, all confined to basal quarter of sclerite. Femoral gland bullae small and ovate, located at or proximal of midlength on middle and hind femora. Propodeal lamella with lower lobe longer narrower and more acute than upper lobe; the latter may be reduced to a tiny blunt triangle. Dorsum of petiole node reticulate-punctate. In profile lateral spongiform lobe of petiole extends forward on side almost to level of anterior face of node. Postpetiole disc traversed from front to back by spaced longiudinal costulae. Basigastral costulae in dorsal view sharply defined but short, longer than thickness of posterior spongiform collar of postpetiole but not as long as disc.

Type Material

Syntype workers and males, GUIANA: Kartabo, 25.vii.1920 (W. M. Wheeler) (Museum of Comparative Zoology, National Museum of Natural History) [examined].
