Dolichestola densepunctata Breuning 1942: 165 ; 1974: 124; Monné 1994: 52 (cat.); Monné and Giesbert 1994: 217 (checklist); Monné 2005: 393 (cat.); Monné and Hovore 2006: 244 (checklist); Wappes et al. 2006: 29 (distr.); Touroult et al. 2010: 32; Dalens and Touroult 2010: 46 (distr.); Morvan and Roguet 2013: 25 (distr.); Monné 2022: 659 (cat.).

Breuning (1942) briefly described D. densepunctata based on a single specimen from French Guiana ( Fig. 11 ) as follows (translated): “Very close to my annulicornis , but the head extremely fine [finely punctate], the pronotum extremely densely punctate; the pubescence finer, forming narrow longitudinal bands on the elytra. 5 mm.” However, the punctures on the pronotum are very similar to those in examined specimens of D. annulicornis , which are slightly variable especially in the density, and, apparently, are equal or nearly so also in the holotypes of D. densepunctata and the latter. Breuning (1974) translated the original description into French, and separated D. densepunctata from D. annulicornis and D. vittipennis by the sculpturing of the pronotum: pronotum extremely finely punctate, leading to D. densepunctata ; and pronotum finely punctate, leading to D. annulicornis and D. vittipennis . This information in the key may suggest that the shape of the punctures is distinctly different, which is not true. In fact, the only reliable difference between D. densepunctata and D. annulicornis is the proportion between the length of the prothorax and elytra. In D. densepunctata , the elytra are proportionally shorter in both sexes ( Fig. 11, 13, 17 ), while they are proportionally longer in both sexes of D. annulicornis ( Fig. 1–6 , 9, 10 ). The punctures on the metaventrite are also very similar in the two species ( Fig. 8 , 14 ).

Currently, D. densepunctata is known from Panama, Bolivia (Santa Cruz), and French Guiana ( Tavakilian and Chevillotte 2021; Monné 2022).
