Tabanus callosus Macquart 

( Figures 7View FIGURE 7 A–D, 8A–D, 31)

Diagnosis. Style subequal to postpedicel, never less than half its length. Scutum and scutellum blackish with grey pruinescence, notopleuron concolorous with scutum and with long black hairs. All coxae and femora black, the former with gray pruinescence Abdomen with three abdominal stripes, the middorsal reaching tergite 6, dorsolateral reaching tergite 4, sometimes with faint indications at 5. Abdomen clearly banded ventrally.

Comments. This species has great resemblance with T. trivittatus  . Both species show a uniform morphology and similar body sizes ( T. trivittatus  ranges from 9 to 16 mm, while T. callosus  ranges from 8 to 14 mm). The major difference between the species is the antennae, where, the postpedicel (basal plate) in T. callosus  is short and in T. trivittatus  the postpedicel is long, usually twice the style length. In addition, the postpedicel tooth angle is closer to the base in T. trivittatus  . Some specimens of T. callosus  seem to possess intermediate states between the two species. There is also great variation between the two in regards to sternite 8 of female genitalia ( Fig. 29 A – FView FIGURE 29). We also observed morphological difference in the males. The male postpedicel of T. callosus  is shorter than T. trivittatus  ( Figs. 8DView FIGURE 8 and 26DView FIGURE 26). In addition, the subcallus is bare and inflated at ventral region in the male of T. callosus  ( Fig. 8C, DView FIGURE 8), but pruinescent and flat in the male of T. trivittatus  ( Fig. 26C, DView FIGURE 26). The differences observed in the males corroborate the hypothesis that these are two different species.
