“…Description Distribution. According to Platnick et al (2012b), who recorded this species in the state of Amazonas, this Pantropical species was probably introduced in Americas from Asia. The present records in Brazil are anecdotic but depict a wide distribution in the Western and Central Amazonia, as well as in the Northeastern state of Sergipe (Fig.…”

“…Male and female, see Platnick et al 2012b:7, figs 1-99. Distribution. According to Platnick et al (2012b), this Pantropical species was probably introduced in Americas from Asia. Our records indicated that it was present only in three Brazilian states, the Northern State of Pará, the Northeastern State of Bahia and in the Southeastern State of São Paulo (Fig.…”

Twelve non-native species of the spider family Oonopidae are recorded in Brazil: Brignolia dasysterna Platnick, Dupérré, Ott & Kranz-Baltensperger, 2011, B. parumpunctata (Simon, 1893), Triaeris stenaspis Simon, 1892, Ischnothyreus peltifer (Simon, 1892), I. velox Jackson, 1908, Opopaea concolor (Blackwall, 1859), O. deserticola Simon, 1892, Pelicinus marmoratus Simon, 1892, Heteroonops spinimanus (Simon, 1892), Gamasomorpha parmata (Thorell, 1890) (herein restored to its original combination in Xestaspis), Orchestina pavesiiformis Saaristo, 2007 and O. dentifera (Simon, 1893). Among these species, six new synonyms were detected: Hytanis oblonga Simon, 1893, Xestaspis bipeltis Thorell, 1895, Gamasomorpha insularis Simon, 1907 and Opopaea lutzi Petrunkevitch, 1929 with Xestaspis parmata Thorell, 1890; Gammasomorpha humilis Mello-Leitão, 1920 with Opopaea concolor (Blackwall, 1859) and Gamasomorpha rufa Banks, 1898 with Opopaea deserticola Simon, 1891. Since Hytanis oblonga is the type species of the genus, its synonymy with Xestaspis parmata imply in the synonymy of Hytanis Simon, 1893 with Xestaspis Simon, 1884. The partenogenetic species T. stenaspis is the most distributed synanthropic oonopid in Brazil, occurring all over the country, mainly in urban areas. Some species are reported here to occur in the interior of natural caves, a finding that should raise conservation concerns.

“…The new species is similar to Ischnothyreus browni Chickering, 1968 (Platnick et al 2012), but can be distinguished from it by the dark brown body color, the (fdp)flake-like dorsal process on the male chelicerae (Fig. 9F, G), the finger-like apophysis on the distal part of the male papal bulb (Fig.…”

“…The new genus is also similar to Ischnothyreus Simon, 1893, but can be separated by the deeply incised labium, the branched endites, the unmodified chelicerae and the totally fused cymbium and bulb in males ( Ischnothyreuspeltifer (Simon, 1892), and most species of this genus usually with a tooth-like projection on the anteromedian tip of the endites, with processes on the base of the cheliceral fang and cymbium fused with bulb but with clearly defined seam, see Kranz-Baltensperger 2011: figure 1C; Richard et al 2016: figure 19C, D; Platnick et al 2012b: figs 7–11, 34; Tong et al 2018: figure 1e) and the T-shaped anterior sclerite (tsc, Figs 3J, 6J) and tube-like posterior receptacle (pr, Figs 3J, 6J) of the endogyne ( Ischnothyreus has an elongated, highly curved sclerotized duct). The new genus is also similar to Trilacuna Tong & Li, 2007 because of the modifications to the male labium and endites, but can be distinguished by the heavily sclerotized palps, the egg-shaped patches behind the eyes in males, the smooth sides of the carapace ( Trilacunarastrum Tong & Li, 2007 has granulates on the sides of carapace, see Tong and Li 2007: figure 1) and the large plate (pl, Figs 3I, 6I) in the endogyne (only T.kropfi Eichenberger, 2011 with a small semicircular plate, see Eichenberger and Kranz-Baltensperger 2011: figure 18B).…”
