description: Hexapopha Platnick, Berniker & Víquez, 2014   
 Hexapopha Platnick, Berniker & Víquez, 2014: 4   
 (type species by original designation Xestaspis reimoseri Fage, 1938).   
 Diagnosis: Hexapopha is easily recognized as a member of the Zyngoonops group by the heavily sclerotized and complex endites of males (Figs 3F, 6F, 16A, 19F; Platnick et al. 2014: figs 9, 64). The genus is distinguished from all other known genera of the group by the combined presence of six eyes (Fig. 3C) (two eyes in Coxapopha), tube-shaped embolus (Fig. 5L) (cone-shaped in Kijabe), lack of an abdominal dorsal constriction (Fig. 3K) (present in Antoonops), lack of remarkable sclerotized modifications on the sternum and pedicel tube (Fig. 3L) (present in Zyngoonops), as well as the absence of a prolateral series of leaf-shaped setae on the male palpal patella (Figs 5I–J) (present in Triaeris).   
 Description: Total length, males 1.29–1.81 (Fig. 1A), females 1.29–1.92 (Fig. 1B). CEPHALOTHORAX.

 Composition. The genus Hexapopha includes 41 species, 35 of which newly described.   
 Distribution. Species of Hexapopha are currently known only from the Neotropical Region. The most northern records are from Costa Rican species and the southernmost ones are from northern Argentina. The genus is widely distributed in Brazil, being recorded here for the first time in all Brazilian biomes. The Brazilian Amazonia harbors 21 species; Atlantic Forest harbors 11 species; the Pantanal harbors two, while the Pampa harbors just one. Two species are found in the Brazilian Cerrado, where one of them is also found in the Cerrado-Caatinga ecotone. A few species, such as H. numerosa sp. nov., H. platnicki sp. nov., and H. izquierdoi sp. nov., are relatively common in collections, but 21 of the species here recognized, all newly described, are known solely from their type localities. The highest species richness occurs in the Amazon basin, with 22 species. Sympatry is recorded in several areas, such as the Una ecological station (State of Bahia), and Novo Repartimento (State of Pará), each with five species; Juruti and the vicinities of Belém (State of Pará), each with four; Ferreira Penna Scientific Station (eastern Brazilian Amazonia, State of Pará) with three; and Corumbá, in the Brazilian Pantanal (State of Mato Grosso do Sul), with two species (Maps 1–6).
