Specimen labels

Dinoponera lucida has been classified as endangered in Brazil by the Ministério do Meio Ambiente (Campiolo et al. 2003) due to habitat destruction in the Atlantic forest.

Identification

Lenhart et al. (2013) - Worker. This species can be recognized by the following combination of character states: anterior inferior pronotal corner with tooth-like process, pilosity long and flagellate with white luster, integument smooth and shiny with bluish luster, scape length longer than head width, petiole slanting obliquely on dorsal edge. Total body length ranges from 27–30mm which is between the lengths of Dinoponera australis and the other larger species.

Dinoponera lucida is only slightly larger than D. australis but differs in its integument micro-sculpturing and pilosity type (see above). Dinoponera lucida can be confused with D. australis but is distinguished by its shiny integument and whitish setae, as opposed to the micro-sculptured integument and dull tan setae of D. australis.

Escarraga et al. (2017) - Male Body bicolored: head, mesosoma, and petiole brown; scape, legs and gaster ferruginous brown. Lateral ocelli protruding beyond posterior cephalic margin in dorsal view of the head; abdominal tergum VIII shaped as acute triangular; body with abundant long yellow hairs.

Keys including this Species

Distribution

Escarraga et al. (2017) - Endemic to the Atlantic Forest of Brazil, recorded from the states of Bahia, Espírito Santo, Minas Gerais, and São Paulo, with most records in Espírito Santo and Southern Bahia. The most northern record is from Ilheus (Bahia) and the southernmost record is from Cruzeiro (São Paulo). There is a single record from São Paulo by Kempf (1971).

Lenhart et al. (2013) - This species inhabits fragments of Atlantic rainforest in the Brazilian state of Espirito Santo, across the border into Minas Gerais, the southern portion of Bahia and São Paulo. It is possible that D. lucida exists in Rio de Janeiro but we are not aware of any specimens from this area. Refer to Mariano et al. (2008) for information on the biogeography of this species. With the locality data available D. lucida is the only species with no known range overlaps with other Dinoponera species.

Biology

Dinoponera lucida is an Atlantic Forest endemic, with most records from the state of Espírito Santo, that has received official recognition as an endangered species (Campiolo & Delabie 2008) due to its restricted distribution within an ecosystem that is dwindling in size and suffering from fragmentation (Saatchi et al. 2001; Ribeiro et al. 2009). Several aspects of the species biology have been studied by Peixoto et al. (2008) and Peixoto et al. (2010). Amongst their results, they found a preference of these ants for dense forests with little herbaceous ground vegetation. Mature nests have sizes that range from 22 to 106 adults, with a nest density of 20–52 nests per hectare.

Associations with other Insects

Scuttle flies (Diptera: Phoridae) have been found attacking workers of this ant species (Disney et al. 2015). Marcos Teixeira collected Diptera of Apocephalus exlucida and two undescribed species of the genus Megaselia attacking and hovering over Dinoponera lucida in the vicinity of study colonies at Aracruz, Espírito Santo State, in David Farina Park 19°55′54″S 40°07′41″W / 19.93167°S 40.12806°W / -19.93167; -40.12806.

Description

Worker

(mm) (n=5) TBL: 27.01–30.39 (28.64); MDL: 3.79–4.31 (3.97); HL: 4.92–5.64 (5.34); HW: 5.02–5.13 (5.07); SL: 5.23–5.64 (5.42); WL: 7.33–8.20 (7.84); PL: 2.25–2.51 (2.39); PH: 3.18–3.28 (3.26); PW: 1.54–1.90 (1.72); GL: 8.00–10.05 (9.10); HFL: 6.87–7.28 (7.18).

A description of the external morphology of the worker is given in Kempf (1971): “Antennal scape distinctly longer than head width. Pubescence on front and vertex of head variable, either short and inconspicuous or longer, denser and quite visible. Gular surface of head finely striate either throughout or at least on anterior half; very seldom the striae are confined to a narrow stripe along the anterior border and obsolescent yet still discernible. Sides of head smooth, not quite glossy but with a silky sheen on account of the superficial reticulate microsculputure. Antero-inferior corner of pronotum dentate. Pronotal disc smooth and shining, lacking wrinkles and dense, fine punctulae; paired swellings quite distinct. Hind tarsus I decidedly longer than head length. Petiole…smooth and polished, its anterior face not excavate, its dorsal face slanted forward; vertical sulcus on posterior face either present or absent; width-length proportion well under 0.80; anterior face lacking dense pubescence. Terga I and II of gaster smooth, highly shining, lacking dense, fine punctulae; pubescence loosely scattered on sides, entirely absent on disc. Stridulatory file on acrotergite of tergum II well developed, nearly crossing the entire tergite.”
