description: Genus Pseudoporatia Golovatch, 1999
TYPE SPECIES. — Pseudoporatia perplexa Golovatch, 1999, by monotypy.
EMENDED DIAGNOSIS. — Based on Golovatch (1999: 228). Pseudoporatia can be distinguished from other Neotropical genera of the family by following combination of characters: collum flabellate, entirely covering the head from above (Fig. 2), with 5 + 5/6 + 6 lobulations; metaterga with 2+ 2 rounded paramedian and distolateral lobes in usual three longitudinal rows (Golovatch 1999: figs 30-32; Fig. 6A, B), and with irregularly scattered middorsal and intercalary small tubercles; paraterga with three lateral marginal lobulations (Fig. 3B, C). Midbody legs unmodified. Males with extremely complex gonopod structure: hemispherical coxae, setose, and strongly papillate (Golovatch 1999: figs 33, 34; Figs 9A; 10C); telopodites nearly fully concealed or exposed from the gonocoel, containing conspicuous, hyaline, fringed lamellae (Golovatch 1999: figs 33, 35; Figs 9-11); prefemoral processes with distal branchlets (Fig. 9 C-F); solenomere fringed, with subterminal opening of seminal groove (Fig. 11B, C). Pseudoporatia resembles the widely distributed genus Poratia Cook & Cook, 1894 in somatic characters (Cook & Cook 1894; Golovatch & Sierwald 2000: 183), but differs mainly in having much more complex gonopods (see Golovatch & Sierwald 2000: 183). The gonopods of Pseudoporatia, with secondary processes on the femoral region and lamellae, superficially resemble those of some non-Neotropical genera such as Cryptocorypha Attems, 1907, Dedalodesmus Silvestri, 1927, and Tonodesmus Silvestri, 1923 (Attems 1907; Silvestri 1923, 1927; Golovatch 1999; Golovatch et al. 2011b; Golovatch & VandenSpiegel 2015), and particularly the Asian genus Ampelodesmus Miyosi, 1956 by the presence of subunciform branchlets, strongly fringed distal lobes, and lamellae partially covering the telopodite (Golovatch et al. 2011a: figs 5, 7). Nonetheless, no putative relationship is inferred between these genera until further phylogenetic analysis is carried out.
COMPOSITION. — Pseudoporatia perplexa Golovatch, 1999, and now including Pseudoporatia kananciue Iniesta, Bouzan, Souza & Brescovit, n. sp.
DISTRIBUTION. — Members of Pseudoporatia seem to be associated with tropical rainforests of the Amazonian region. The distribution of the genus is here extended from the Madeira province in the Brazilian subregion (Amazonas state, Brazil) up to the Xingu-Tapajós province in the Chacoan subregion (Pará state, Brazil).
