The goblin spider genus Pescennina Simon has been known only from females of its type species from Venezuela, whereas the more recently described genus Marsupopaea Cooke has been known only from males taken in Colombia. Discovery of the missing sexes, in both cases, indicates that these spiders belong to the Scaphiella complex; males have dorsal abdominal scuta that are absent in females. The presence, in the males of both type species, of a terminal, coiled embolus that can be held in an excavated "pouch" at the anterior edge of the sternum and is matched by coiled anterior ducts in the female genitalia, suggests that these taxa are congeneric. Marsupopaea is therefore newly synonymized with Pescennina, and its type species, M. sturmi Cooke, is placed as a junior synonym of P. cupida (Keyserling). Species of Pescennina occur widely in North, Central, and South America; many are apparently ant mimics, with color patterns (and sometimes a constricted abdomen) that enhance their antlike appearance. Although most of the species seem to be ground dwelling, with the extremely narrow geographic ranges typical of goblin spiders, at least four species inhabit the forest canopy, and at least one of those species is much more widespread. Males of the type species, P. epularis Simon, and females of P. cupida (Keyserling) are described for the first time; 16 new species are described: P. iviei, P. gertschi, P. sumidero, and P. ibarrai from Mexico; P. murphyorum from Nicaragua and Costa Rica; P. viquezi from Costa Rica; P. laselva from Costa Rica and Panama; P. fusca from Panama; P. arborea from Panama, Colombia, and Ecuador; P. magdalena and P. sasaima from Colombia; P. orellana from Ecuador; P. piura and P. loreto from Peru; P. grismadoi from Bolivia; and P. otti from southern Brazil.

Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.

The type species of Costarina, C. plena (O. P.-Cambridge), is redescribed, has an unusually broad distribution (extending from southern Mexico to northern Costa Rica), and is sometimes sympatric with a relatively widespread new sibling species, C. subplena. The same region also houses 26 additional new species with much smaller distribution ranges: C. iviei, C. llama, C. oaxaca, C. mixtepec, C. naja, C. sepultura, and C. bochil from southern Mexico, C. belmopan, C. peten, C. macha, C. cahui, C. morales, and C. izabal from Belize and Guatemala, C. cortes, C. cofradia, C. cusuco, C. tela, C. ceiba, C. branstetteri, C. olancho, C. muralla, C. coma, and C. gracias from Honduras, and C. waspuk, C. musun, and C. blanco from Nicaragua. At least 11 of these highly localized, microdistributed species have been taken in sympatry with C. plena. Because C. plena and C. subplena are the only members of the genus that have been collected in western and southern Guatemala, we suspect that this area represents the original range of one or both of the widespread species. However, five pairs of the microdistributed species have also been taken in sympatry with each other (and in one case together with C. plena as well).

The goblin spider genus Heteroonops is relimited to include those soft-bodied oonopids with anteriorly situated, posteriorly directed projections on the endites of males, and elongated, highly spinose pedipalps in females, and is hypothesized to be natively circum-Caribbean. The type species, H. spinimanus (Simon), has attained a pantropical distribution, has been known only from females, and has therefore been hypothesized to be parthenogenetic. Although the species may have some parthenogenetic populations, males have apparently been collected together with females twice, once in the Seychelle Islands and once in Florida. We therefore place Matyotia tetraspinosus Saaristo (a monotypic genus and species established for that Seychelle specimen) as the male (and hence a junior synonym) of H. spinimanus; Oonopinus hunus Suman, described from Hawaii, is also newly synonymized with H. spinimanus, which is newly recorded from Mexico, the Bahama Islands, Colombia, Madeira, Madagascar, the Marquesas Islands, the Cook Islands, Pitcairn Island, Fiji, New Caledonia, and Queensland. Four specific names are transferred to Heteroonops: Oonops singulus Gertsch and Davis (from Mexico), O. validus Bryant (from Hispaniola), O. castellus Chickering (from the Virgin Islands), and O. delegenus Chickering (from Puerto Rico); H. delegenus is placed as a junior synonym of H. castellus, and the female of H. validus is described for the first time. Ten new species are described: H. murphyorum from Costa Rica, H. andros from the Bahama Islands, H. spinigata from Jamaica, H. vega, H. iviei, and H. castelloides from Hispaniola, H. toro from Puerto Rico, H. croix from the Virgin Islands, H. saba from Saba and Montserrat, and H. macaque from Dominica. Because the status of Heteroonops as a genus separate from Oonops Templeton has been questioned, we present a redescription of the family's type species, Oonops pulcher Templeton, based on topotypical specimens from Scotland; it is unlikely that any of the plethora of New World species that have been assigned to Oonops are actually congeneric with O. pulcher.

The goblin spider genus Oonopoides Bryant was established for a species from Cuba, Oonopoides maxillaris Bryant, and most of the species that have subsequently been assigned to the genus are from that island. The group is actually circum-Caribbean in distribution, but many of its members have been misplaced in the genus Oonops Templeton; here we treat those representatives of the genus that have been collected in North and Central America. Six specific names are transferred from Oonops to Oonopoides: O. endicus Chickering from Florida and the Bahama Islands, O. secretus Gertsch from Texas and Tamaulipas, O mitchelli Gertsch from Mexico, and O. pallidulus (Chickering), O. tenebus Chickering, and O. anoxus Chickering from Panama. Males of O. zullinii Brignoli from Mexico and females of O. secretus are described for the first time; O. tenebus is placed as the male, and hence a junior synonym, of O. pallidulus. The holotype of Oonops zeteki Chickering from Panama is a juvenile that probably belongs to Costarina Platnick and Dupérré and the name is placed as a nomen dubium. Eight new species are described: O. iviei from Florida and the Bahama Islands, O. catemaco, O. chicanna, and O. kaplanae from Mexico, O. hondo from Honduras, O. cristo and O. upala from Costa Rica, and O. cartago from Costa Rica and Panama.

The Costarina faunas of Panama and Colombia are revised. Because Chickering described the sexes from his Panamanian collections separately, several of his names based only on females are placed as junior synonyms of names based only on males: C. humphreyi (Chickering) is newly synonymized with C. recondita (Chickering), as are C. belinda (Chickering) with C. intempina (Chickering), C. rigida (Chickering) with C. abdita (Chickering), C. silvatica (Chickering) with C. dura (Chickering), and C. improvisa (Chickering) with C. seclusa (Chickering). The Costa Rican species C. pittier Platnick and Berniker is newly recorded from Panama. Nine new species are described from Panama (C. sorkini, cerrocol, bocas, chiriqui, clara, fortuna, almirante, dybasi, and tskui), as are 11 from Colombia (C. sasaima, suiza, otun, choco, yotoco, saladito, antonio, anchicaya, gorgona, helechal, and taraira). Previous studies on more northern species are supplemented; newly available collections from Nicaragua reveal the presence there of two new species (C. kilambe and diablo), and locality records are provided for the Costa Rican members of the genus.

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.
