Remarks. Lupaeus waldumirus Wurlitzer & Monjarás-Barrera sp. nov. shows a dark orange color ( Fig. 8B View FIGURE 8 ).

Diagnosis. The new species resembles Lupaeus damavandiani Paktinat-Saeij & Castro, 2016 , for its dorsal morphometry, ventral striae, arrangement of genital setae, and chaetotaxy of coxae III–IV, trochanters I–IV, basifemora I–IV, telofemora I–IV, genua III, tibiae II, III and IV. The different morphological characters are shown in Table 2 View TABLE 2 .

Etymology. The epithet is in honor of the grandfather of the first author, Mr. Waldomiro Moraes Borges, a conservationist who always cherished agroecology and nature.

Type material.
