RESUMO

The pseudoscorpion family Withiidae is widely distributed around the world, with most of its diversity in tropical areas. Five new species and a new genus from Colombia are described: Cystowithiusflorezisp. nov., Parawithiusbromelicolasp. nov., Oligowithiusachaguasp. nov., and the genus Paciwithiusgen. nov. with two species Paciwithiusvalduparensissp. nov. and Paciwithiuschimbilacussp. nov. A reassessment of the subgenus Dolichowithius (Oligowithius) Beier, 1936 allows the elevation to a full generic level, and the transfer of the only known species to Oligowithius, forming the new combination Oligowithiusabnormis (Beier, 1936), comb. nov.

RESUMO

The pseudoscorpion genus Rhopalochernes Beier, 1932 is restricted to the Neotropical region and currently includes eight species. Recent field collections in the Caribbean region of Colombia have revealed the presence of two previously undescribed species, which are here described as Rhopalochernes luiscarlosi sp. nov. and Rhopalochernes catalinae sp. nov. They differ from one another by the shape of the carapace, the position of the trichobothria and the length of the nodus ramosus. They differ from other species of the genus by the absence of eye spots, and the number of the cheliceral setae. One of these features, the presence of only four setae on the cheliceral hand, is shared with R. panamensis Heurtault, 1998 and R. chamberlini Heurtault, 1998, with other species possessing a higher number. Additionally, the key for the genus proposed by Beier (1932) is updated for included all the species.

RESUMO

The pseudoscorpion genus Verrucachernes Chamberlin, 1947 is widely distributed in the Old World tropics, with three named Australasian and West Pacific species and two from Africa. A review of some pseudoscorpions described from India has revealed that Withius parvus Beier, 1930 (currently in the genus Metawithius) and Pselaphochernes indicus Beier, 1974 are misplaced and actually belong to the genus Verrucachernes Chamberlin, 1947, forming the new combinations V. parvus (Beier, 1930) comb. nov. and V. indicus (Beier, 1974) comb. nov., respectively. Both species possess the single, large, rounded spermatheca and other features typical of Verrucachernes.

RESUMO

The goblin spider genus Cinetomorpha Simon is removed from the synonymy of Gamasomorpha Karsch and treated as the senior synonym of Yumates Chamberlin and Lucetia Dumitresco Georgesco. All 41 species occur only in the New World, and the genus is divided into four species groups: the simplex group, the puberula group, the patquiana group and the itabaiana group. The following species are transferred to Cinetomorpha: C. floridana (Banks), comb. nov., and C. sedata (Gertsch Mulaik), comb. nov., from Opopaea; C. angela (Chamberlin), comb. nov., and C. nesophila (Chamberlin), comb. nov., from Yumates; and C. patquiana (Birabén) and C. platensis (Birabén), comb. nov., from Gamasomorpha. Gamasomorpha wasmanniae Mello-Leitão and Lucetia distincta Dumitresco Georgesco are newly synonymized with C. simplex Simon. Two species currently in Gamasomorpha are transferred to Hexapopha Platnick Berniker: H. brasiliana (Bristowe), comb. nov. and H. m-scripta (Birabén), comb. nov. The following 31 species are newly described: C. adaga Ott Bonaldo (Brazil, Colombia, Ecuador and Peru); C. atlantica Ott Brescovit (Brazil); C. baja Ott Ubick (Mexico); C. bandolera Ott Harvey (Mexico USA); C. boraceia Ott Brescovit (Argentina and Brazil); C. campana Ott Harvey (Chile); C. central Ott Brescovit (Brazil); C. chicote Ott Bonaldo (Brazil, Colombia, Ecuador and Peru); C. concepcion Ott Harvey (Chile); C. iguazu Ott Brescovit (Argentina and Brazil); C. itabaiana Ott Brescovit (Brazil); C. laguna Ott Ubick (Mexico); C. lavras Ott Brescovit (Brazil); C. longisetosa Ott Harvey (Costa Rica and Brazil); C. lorenzo Ott Harvey (Guatemala); C. loreto Ott Bonaldo (Peru); C. nayarit Ott Harvey (Mexico); C. orellana Ott Bonaldo (Ecuador); C. pauferro Ott Brescovit (Brazil); C. peluda Ott Harvey (Chile); C. pinheiral Ott Brescovit (Brazil); C. pocone Ott Brescovit (Brazil); C. punctata Ott Brescovit (Brazil); C. quillota Ott Harvey (Chile); C. rinconada Ott Harvey (Chile); C. santamaria Ott Brescovit (Argentina); C. similis Ott Brescovit (Brazil); C. sternalis Ott Bonaldo (Brazil); C. sur Ott Ubick (Mexico); C. waorani Ott Bonaldo (Ecuador); and C. zero Ott Harvey (Mexico to Venezuela).
