Paratropus castaneus Lewis, 1891: 391 . Lectotype, hereby designated: “ Mexique ”/ “G. Lewis Coll. B.M. 1926-369.”/ “ Syntype ”/ “ Type ”/ “ Paratropus castaneus Lewis Type ”/" LECTOTYPE Paratropus castaneus Lewis M. Caterino & A. Tishechkin des. 2008", BMNH; Paralectotype: “ Mexique ”/ “G.

Diagnosis: L: 2.88; W: 2.62; E/Pn L: 1.68; E/Pn W: 1.19; Pn W/L: 2.04; E L/W: 0.69; Pr/Py: 0.97; Sterna: 0.84, 0.27, 0.70; Tibiae: 0.67, 0.80, 0.88 (n=3). This species is easily recognized by the unique setose 'pustules', enlarged, slightly raised pits bearing conspicuous, faintly scale-like setae. These are observed on essentially all body surfaces, but especially the frons, pronotum and elytra. In addition to being coarser, these setae are fewer and sparser than in the only other dorsally setose species, H. californicus .

Distribution: This species is known from the unspecified type locality in Mexico ( Lewis, 1891), and from recent material from northwestern Belize. No specimens of the species have been associated with host ants.

Material: one female (excluding type material) from Belize: Orange Walk District, Rio Bravo Conservation Area, 2nd Logging Rd. off main Rd. to Archeological Site, collected with flight intercept traps by P.W. Kovarik on July 18–20, 1996 (PWK).
