Specimen Labels

A soil nesting species that appears to be most active in its foraging at night. One excavated nest was found to contain 120 workers. (Morgan 1993, as reported in Lenhart et al. 2013)


Lenhart et al. (2013) - Worker. This species can easily be recognized by the golden luster of its conspicuous long, flagellate hairs especially on the frons. In addition this species has the following combination of character states: pronotal corner rounded without tooth-like process (Fig. 1E), no gular striations, a reflective, smooth and shiny integument. All specimens have a petiole which bulges on the dorso-anterior edge except for those from the Rio Madeira and Rio Negro in Brazil.

Male. Distinguished from other Dinoponera by the following combination of character states: funiculus of antennae with short, thick decumbent setae; pygidial spine shorter than in Dinoponera gigantea and Dinoponera quadriceps but longer and narrower than in D. australis and D. snellingi, volsella with broad basal lobe covered in minute teeth.


Keys including this Species


Dinoponera longipes have been collected in eastern Perú in the departments of Loreto, Amazonas, Huánuco, San Martin and Pasco, as well as Ecuador in the province of Pastaza. In Colombia it has been recorded near the Peruvian border in the department of Amazonas. In Brazil, D. longipes has been found in Acre, Amazonas as far east as Manaus, as well as along the Rio Madeira in Rondônia (Lenhart, Dash & Mackay, 2013).

Type Material

Lenhart et al. (2013) - Holotype worker PERÚ: Cumbase (Museo Civico di Storia Naturale, Genoa) [examined]. Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.



Lenhart et al. (2013) - (mm) (n=16) TBL: 30.85–34.75 (32.83); MDL: 4.61–5.33 (4.89); HL: 5.48–6.87 (6.12); HW: 5.23–5.84 (5.57); SL: 5.54–6.56 (6.23); WL: 7.84–9.33 (8.51); PL: 2.46–2.82 (2.64); PH: 2.77–3.59 (3.28); PW: 1.44–1.85 (1.67); GL: 9.02–12.20 (10.67); HFL: 7.48–8.87 (8.36).

A description of the external morphology of the worker is given in Kempf (1971): “Antennal scape from slightly shorter to slightly longer than maximum head width (index: scape L/head W × 100 = 94–103). Pubescence on front of head (as well as on thorax and dorsum of gaster) golden brown, very dense and rather long. Gular face of head smooth and shining, without vestiges of striae antero-laterally. Antero-inferior corner of pronotum obtusely angulate, not dentate. Pronotal disc smooth and shining, but densely covered with piligerous punctulae; paired swellings from faint to distinct; integument not wrinkled. Tarsus I of hind leg decidedly longer than maximum length of head capsule. Petiole smooth and shining; shape resembling that of quadriceps…, dorsal surface faintly to distinctly slanted backwards; width-length proportion distinctly lower than 0.80: vertical sulcus on posterior surface present in specimens from Acre Territory, Brasil, absent in specimens seen from Perú. Terga I and II of gaster smooth and shining but densely covered with punctulae from which arises the long and dense pubescence that covers the entire segments. Stridulatory file on acrotergite of Tergum II of gaster very short but broadly triangular, not extending backwards beyond the anterior half of acrotergite.”
