Specimen labels

Longino (Ants of Costa Rica) - Strumigenys longispinosa occurs in lowland wet forest. Workers forage in leaf litter on the forest floor. Weber (1952) observed the nest of the type collection, from Barro Colorado Island, Panama. The nest was in rainforest soil, below the soil cover, and surmounted by a small crater.

Identification

Bolton (2000) - A member of the Strumigenys marginiventris-group. Closely related to Strumigenys incuba and like that species having the postpetiole and gaster unsculptured. However, incuba is larger, has only a single pair of erect hairs on the cephalic dorsum, and has gastral hairs that are not flagellate.

Longino (Ants of Costa Rica) - Apical fork of mandible without intercalary teeth; mandible with one strong preapical tooth; gaster smooth and shining with strong basal costulae; gaster with long flagelliform setae.

Description

Worker

Bolton (2000) - TL 2.8-3.3, HL 0.67-0.82, HW 0.50-0.62, CI 72-76, ML 0.58-0.72, MI 83-90, SL 0.58-0.70, SI 113-120, PW 0.28-0.36, AL 0.66-0.80 (8 measured).

Cephalic dorsum with 2 pairs of erect simple hairs, one near highest point of vertex, the other close to the occipital margin. Flagellate hairs present: in apicoscrobal position; at pronotal humerus; a pair on mesonotum; a few on waist segments; numerous on first gastral tergite. Ventral spongiform strip on petiole narrow, often incomplete, broken or partially absent. Mesopleuron smooth, metapleuron and side of propodeum lightly punctulate at least in part. Propodeal spines long and slender, subtended by a narrow concave carina. Petiole node longer than broad in dorsal view. Disc of postpetiole mostly or entirely smooth, never completely traversed by costulae nor densely reticulate-punctate. First gastral tergite smooth behind basigastral costulae.

Type Material

Bolton (2000) - Holotype and paratype workers, PANAMA: Canal Zone, Barro Colorado Island, 10.vii.1939, No. 1139 (N. A. Weber); paratypes PANAMA: Barro Colorado Island, No. 65-2 (E. C. Williams); Quipo (J. Zetek) (American Museum of Natural History, National Museum of Natural History, Museum of Comparative Zoology, Museu de Zoologia da Universidade de Sao Paulo) [examined].
