Book Description
A new genus, Varioonops, is established for a group of species characterized by sexual dimorphism in abdomen morphology (with a dorsal scutum present in males but not females), male palps with a separate cymbium and bulb, and a patterned abdomen. The closest relatives of the new genus appear to be three similar, but as yet undescribed, Neotropical genera that share those characters, but the members of Varioonops are united by a putative synapomorphy that does not seem to occur in those undescribed groups: a granulated sternum. Attention is drawn to the cymbial cone, a structure (possibly a receptor) found near the tip of the cymbium in Varioonops, members of the Orchestininae, and at least some soft-bodied members of the Oonopinae. A total of 23 new species are described: V. cafista (the type species), V. velsala, V. montesta, V. spatharum, V. poas, V. varablanca, V. tortuguero, V. veragua, V. heredia, and V. girven from Costa Rica, V. ramila and V. sansidro from Costa Rica and Panama, V. funator and V. cerrado from Panama, V. edvardi and V. sinesama from Colombia, and V. yacambu, V. trujillo, V. pittieri, V. chordio, V. parlata, V. potaguo, and V. grancho from Venezuela.

Book Description
Two new genera, Ponsoonops and Bipoonops, are established for groups of species characterized by sexually dimorphic dorsal abdominal scutum expression (with a scutum present in males but not females), male palps with a separate cymbium and bulb, and a patterned abdomen. Both genera belong therefore to the Varioonops complex, represented now by three described Neotropical genera. Members of Ponsoonops are united by three putative synapomorphies in males: a "pierlike" dorsal scutum completely fused to the epigastric scutum, a patch of short setae ventrodistally on metatarsi I and II, and a short anteromedian protrusion on the endites. Female Ponsoonops specimens differ from other members of the Varioonops complex in having small lateral sclerites at the epigynal area and a smooth sternum. Members of Bipoonops share a large, irregularly shaped, rather indistinct dark spot posteriorly on the carapace, a putative synapomorphy, and a moderately rugose sternum surface; males are characterized by a distinct, bipartite conductor. A total of 22 Ponsoonops species, 21 new to science, are described: P. duenas, P. hamus, and P. tacana from Mexico, Guatemala, and Belize, P. bilzi, P. lucha, P. samadam, P. sanvito, and P. viejo from Costa Rica, P. bollo, P. boquete, P. coiba, P. fanselix, P. frio, P. lerida, P. mirante, P. panto, P. salimsa, and P. vuena from Panama, P. pansedro from Colombia, P. micans (Simon, transferred from Dysderoides) from Venezuela, P. yumuri from Cuba, and P. lavega from the Dominican Republic. Bipoonops is described for three new species found on the western slope of the Andes in Ecuador: B. baobab, B. pucuna, and B. tsachila.

Book Description
A new genus, Reductoonops, is established for a group of New World soft-bodied oonopine spiders, found from Mexico south to Chile, characterized by reduced size, a flattened clypeus, loss of the posterior median spinnerets, and often by loss of the four posterior eyes. Members of this group resemble those of Stenoonops Simon but lack the clump of short setae found on the dorsal surface of the palpal tarsus of both sexes in that genus, and often have four pairs of deep channels at the sides of the sternum, the most anterior pair of which demarcate a short, trapezoidal, anterior portion of the sternum. A total of 34 new species are described from Mexico (chamela, armeria, niltepec, real, nubes, jabin), Costa Rica (monte, lucha), Costa Rica and Panama (naci), Panama (almirante, escopeta, bayano), Jamaica (ferry), Curaçao (hato), Martinique (diamant), Colombia (marta, sasaima, meta, leticia), Ecuador (tandapi, pichincha, tina, domingo, otonga, palenque, napo, jatun, hedlite, molleturo, celica, yasuni), the Galapagos Islands (pinta), Peru (carpish), and Chile (elqui).

The New World Goblin Spiders of the New Genus Neotrops (Araneae, Oonopidae).

Book Description
A new genus of soft-bodied oonopids, Neotrops, is established for a large assemblage of goblin spiders found in all tropical and subtropical areas of the Neotropical region, from Panama to Uruguay and central Argentina. Members of Neotrops have spinose forelegs, and share a general palpal morphology with those of Heteroonops Dalmas, but have a prolateral conductor connected with an internal bulbal vesicle that presumably discharges its secretion through a prolateral slit. Females lack a posterior receptacle in the internal genitalia, having only a posterodorsal plate serving for muscle attachment. Here we treat all the species except those from Brazil, which will be addressed in a subsequent paper. Twenty-three new species are described: N. darwini (type species), N. lorenae, and N. sciosciae (from Argentina and Uruguay); N. yunga, N. piacentinii, N. poguazu, and N. lopardoae (from Argentina); N. rubioi, N. pombero, and N. avalosi (from Argentina and Paraguay); N. labarquei (from Uruguay), N. yabare, N. izquierdoi, and N. kopuchianae (from Bolivia); N. pithecia, N. silvae, and N. pakitza (from Peru); N. platnicki, and N. waorani (from Ecuador); N. santamarta and N. caparu (from Colombia); and N. maracay and N. amacuro (from Venezuela). Four additional species, previously placed in Oonops Templeton, are transferred here to Neotrops: O. nigromaculatus Mello-Leitão, from Argentina and Uruguay; O. tucumanus Simon, from Argentina; O. donaldi Chickering, from Panama; and O. trapellus Chickering, from Trinidad and Venezuela. The females of the three latter species are here described for the first time. Most of the species are known from the leaf litter or the foliage of tropical and subtropical forests, but also from grasslands in the southern parts of their distributional range, where they appear as the dominant soft-bodied oonopids. The relationships of this new taxon are briefly discussed, and intrageneric groupings are also proposed.
