Paradysderina and Semidysderina.

121 p. : ill. ; 26 cm.A new genus, Paradysderina, is established for a speciose group of Andean goblin spiders belonging to the Dysderina complex. Members of Paradysderina resemble those of Scaphidysderina Platnick and Dupérré in having the dorsal abdominal scutum of females either greatly reduced or entirely absent, but lack the highly crenulated sternum characteristic of Scaphidysderina and have instead a distinctively flattened, rugose sternal surface. Males of various species of Paradysderina show a wide range of remarkable autapomorphies, including projections at the sides of the clypeus and various kinds of excavations and projections on or between the chelicerae. Several species share the highly unusual occurrence of asymmetry between the left and right male pedipalps; in some species the asymmetry involves the size of the palpal bulb, but in those and other cases, the embolus structure also differs consistently between the two sides, to such an extent that if the left and right palps were studied in isolation, they would be considered to belong to different species. Dysderina globosa (Keyserling) from Colombia and D. montana (Keyserling) from Peru are transferred to Paradysderina, and their males are described for the first time. A total of 52 new species are described, including 26 from Peru (P. watrousi, P. consuelo, P. excavata, P. silvae, P. malkini, P. maldonado, P. asymmetrica, P. apurimac, P. convencion, P. macho, P. tambopata, P. schizo, P. wygodzinskyi, P. newtoni, P. thayerae, P. carpish, P. rothae, P. tabaconas, P. sauce, P. piura, P. tambo, P. fatima, P. bagua, P. yasua, P. loreto, and P. pithecia), 15 from Ecuador (P. zamora, P. lostayos, P. puyo, P. hermani, P. yanayacu, P. baehrae, P. righty, P. centro, P. fusiscuta, P. lefty, P. vlad, P. yasuni, P. dracula, P. pecki, and P. sucumbios), and 11 from Colombia (P. imir, P. pinzoni, P. leticia, P. pira, P. vaupes, P. huila, P. chingaza, P. boyaca, P. carrizal, P. monstrosa, and P. chinacota); P. loreto is also recorded from far western Amazonas, Brazil. A second new genus, Semidysderina, is established for species that share with Scaphidysderina and Paradysderina the absence of a dorsal scutum in females and a spinneret scutum in both sexes, but differ in having a groove connecting the posterior spiracles. Six new species of Semidysderina are described from Colombia (S. lagila, S. kochalkai, S. donachui, S. marta, S. mulleri, and S. sturmi). At least four of these species, from the Sierra Nevada de Santa Marta, are remarkable for the retention of a distinct seam between the male palpal cymbium and bulb

Scaphidysderina.

51 p. : ill. (some col.) ; 26 cm. "April 28, 2011."Dysderina Simon is one of the largest of the classical genera of goblin spiders, containing numerous species that have been associated only because they are heavily scutate gamasomorphines with long, paired spines on the ventral surface of the anterior tibiae and metatarsi. The Old World species that have been assigned to the genus are wildly misplaced, and the New World fauna constitutes a complex of over 225 species belonging to at least nine genera. The northern Andes house a highly diverse fauna, both of Dysderina itself and of closely related genera. The new genus Scaphidysderina is established for one of those related but distinct Andean groups, characterized by a crenulated sternum and by the reduction or loss of the dorsal abdominal scutum in females. Seventeen new species are described from Peru (S. manu, S. pagoreni, S. scutata, S. cajamarca), Ecuador (S. tayos, S. loja, S. molleturo, S. tapiai, S. pinocchio, S. palenque, S. tandapi, S. napo, S. baerti, S. cotopaxi, S. andersoni), and Colombia (S. hormigai, S. iguaque). Males of several species show remarkable modifications of the chilum and chelicerae; the chilum is sometimes enlarged to form a conspicuous snout, and the chelicerae often bear a heavily sclerotized, dorsally directed spine. A second new genus, Costarina, is established to contain the most commonly encountered species that have been misplaced in Dysderina; Dysderina plena O. P.-Cambridge, from Mexico, is chosen as the type species, and 15 additional taxa, all described from Central America by Chickering, are transferred from Dysderina to Costarina: D. abdita, D. belinda, D. concinna, D. dura, D. humphreyi, D. improvisa, D. intempina, D. meridina, D. obtina, D. potena, D. recondita, D. rigida, D. seclusa, D. silvatica, and D. watina

Simonoonops.

30 p. : ill. (some col.) ; 26 cm.The goblin spider genus Simonoonops Harvey has been known only from its Venezuelan type species, but the group occurs also in Guyana and the Lesser Antilles. Most of its members have been misplaced in the genus Dysderina Simon; D. princeps Simon, D. spinigera Simon, D. craneae Chickering, D. globina Chickering, D. soltina Chickering, and D. zinona Chickering are transferred to Simonoonops. Members of Simonoonops resemble those of Dysderina in having three transverse ridges on the sternum, but differ in lacking a groove connecting the anterior spiracles and having a more complex embolic region on the male palp. Two specific names are newly synonymized: S. orghidani (Dumitrescu and Georgescu) with S. craneae, and S. zinona with S. soltina. Six new species are described: S. simoni, S. grande, and S. andersoni from Venezuela, S. lutzi from Guyana, S. etang from Grenada, and S. chickeringi from Saint Vincent

Escaphiella, new genus of goblin spiders.

151 p. : ill. (1 col.), maps ; 26 cm. "Issued September 3, 2009." Includes bibliographical references (p. 146-147, 149-151) and index.A new genus, Escaphiella, is established for a group of 36 oonopid species found from the United States south to Chile and Argentina. The previously known species had been placed in Scaphiella Simon, and Escaphiella is hypothesized to be the sister group of that genus. Members of the two groups share a laterally extended ventral abdominal scutum and a distinctive female genitalic conformation, but differ in cheliceral shape and setation, female palpal tarsal shape, male and female palpal tarsal setation, embolus form, and posterior respiratory structure. At least seven species of Escaphiella are characterized by the highly unusual occurrence of asymmetry between the right and left male pedipalps. In at least eight species, the right and left posterior median spinnerets are fused into a single median projection, or even lost entirely. Nine specific names are transferred from Scaphiella: S. hespera Chamberlin ‪(‬chosen as the type species‪)‬, S. litoris Chamberlin, S. juvenilis ‪(‬Gertsch and Davis‪)‬, S. iguala Gertsch and Davis, S. schmidti Reimoser, S. gertschi Chickering, S. itys Simon, S. scutata Chickering, and S. argentina Birabén. Two of those names are newly synonymized: E. juvenilis with E. hespera, and E. scutata with E. itys. The female of E. hespera is described for the first time, and 29 new species are described: E. nye from California and Nevada, E. acapulco, E. colima, E. catemaco, E. tonila, E. chiapa, E. nayarit, E. magna, and E. olivacea from Mexico, E. viquezi from Honduras and Nicaragua, E. tayrona, E. betin, and E. gigantea from Colombia, E. bolivar from Venezuela, E. cidades, E. hesperoides, E. maculosa, E. cachimbo, E. aratau, E. bahia, E. pocone, E. blumenau, and E. morro from Brazil, E. exlineae from Peru, E. peckorum from Argentina, E. ramirezi from Argentina and Uruguay, E. ocoa from Chile, and E. cristobal and E. isabela from the Galapagos Islands

Scaphioides and Hortoonops.

62 p. : ill. (some col.) ; 26 cm.The genus Scaphioides Bryant contains species that resemble those of Stenoonops Simon but lack the sternal and palpal synapomorphies of that genus and have a longitudinal ridge on the male endites, a short, wide male embolus, and a more heavily sclerotized epigastric scutum in females. As delimited by those characters, the genus is circum-Caribbean in distribution and contains at least 19 species, including 11 described as new: S. campeche from the Yucatan peninsula of Mexico, S. irazu from Costa Rica, S. bimini and S. gertschi from the Bahama Islands, S. camaguey, S. granpiedra, S. siboney, S. cobre, and S. yateras from Cuba, S. miches from Hispaniola, and S. reductoides from the Virgin Islands. The male of S. halatus (Chickering) is described for the first time. A new genus, Hortoonops, is established for three similar Caribbean species that lack the synapomorphies of both Stenoonops and Scaphioides, but are united by peculiar excavations on the anterior metatarsi that represent an extraordinary convergence with the structures found in the African corinnid genus Hortipes Bosselaers and Ledoux. Stenoonops lucradus Chickering from the Virgin Islands and Stenoonops portoricensis Petrunkevitch from Puerto Rico are transferred to Hortoonops, and a new species, H. excavatus, is described from Hispaniola
