Description. Worker . HW 0.63–0.70 (n=3); mandible with three teeth on masticatory margin, second tooth from base largest; subapical tooth with distinct reclinate denticle at base; subapical tooth about 3 × as long as apical tooth; intercalary teeth distinct, one closest to apical tooth about half as long as apical tooth; labrum trapezoidal, anterior margin bilobed, lateral lobule triangular, longer than medial lobule, medial lobules rounded, flanking semicircular median notch; arcuate promesonotal groove and metanotal groove distinctly impressed; propodeal tooth large, acute, infradental lamella wide and forming a secondary convex lobe below tooth; squamiform setae abundant on first gastral tergite, uniformly covering entire tergite; gastral setae relatively short, 2 × longer than wide, tapering evenly from apex to base. The queen and male are unknown. Biology. This species occurs in cloud forest, from 1300–1440 m elevation. It is known from two montane sites: Sierra de Agalta in eastern Honduras , where it is sympatric with R. therion , and Cusuco National Park in northwestern Honduras . The three known specimens are from Winkler samples of sifted leaf litter. Etymology. Referring to Robert S. Anderson, coleopterist extraordinaire.
