Epigyne (Figs 14 D – E, 17 D – E): hexagonal median sector with pointed posterior lateral projections, shaped like an arrow; lateral projections of the lateral sector short, as wide as long; straight copulatory ducts; small fertilization ducts.
diagnosis
Diagnosis. Males of Bulboctenus munduruku sp. nov. resemble those of B. itunaitata sp. nov. by the apical projections of the MA well differentiated and the RTA enlarged (Figs 12 A – C, 14 A – C, 16 A – C, 17 A – C), but can be distinguished by the apical projection of the MA elongated, strongly curved anteriorly (Figs 14 A – C, 17 A – C), while B. itunaitata sp. nov. presents the apical projection of the MA slightly curved anteriorly and pointing prolaterally (Fig. 12 B). Females of Bulboctenus munduruku sp. nov. resemble those of B. itunaitata sp. nov. by having the copulatory ducts separated (Figs 12 D – E, 14 D – E, 16 D – E, 17 D – E) but can be distinguished by the posterior lateral projections (PLP) of the MS distally narrow and pointed, the lateral projections (LP) of the lateral sectors as wide as long, distally curved, and the copulatory ducts well separated, at least by the width of a copulatory duct (Figs 14 D – E, 17 D – E), while B. itunaitata sp. nov. presents the copulatory ducts relatively close to each other, the LP enlarge and straight and the PLP distally rounded (Figs 12 D – E, 16 D – E).
distribution
Distribution. Santarém, Pará, Brazil (Fig. 19).
etymology
Etymology. The species name is a noun in apposition that honors the Munduruku indigenous people from the state of Pará. The term “ Munduruku ” is used by neighboring tribes rather than the Munduruku people themselves, and it means “ red ants ”.
