This tiny (2.1–2.6 mm) species of Typophorus is relatively easy to recognize because of its brownish color, when many species of Typophorus have bright tones, the impunctate pronotum, and the apex of tibiae and tarsi paler than the remainder of legs ( Fig. 6f ). The species was reported from Belize and Guatemala (Jacoby 1882; Clavareau 1914; Bechyné 1953; Flowers 1996), and its presence in Nicaragua expands considerably its range south. Together with T. apicicornis reported above, this species presents some structural facial differences relative to typical Typophorus . Most notably, they both have a wide, subparallel, uninterrupted, and, at most, slightly depressed transition between frons and clypeus, lacking the characteristic transverse furrow dividing the frontoclypeus in Typophorus and more in line with the typical facial structure of Paria (Jacoby 1882) . However, these two species have wide, posteriorly enlarged supraocular sulci, characteristic of Typophorus (and lacking in Paria , for example), and for the time being, even though we acknowledge that they will likely require a new generic combination, we chose to treat them in their original genus for stability. We illustrate male genitalia ( Fig. 3g ) and spermatheca ( Fig. 5n ) of this species for the first time.
