Abstract
A new genus, Noonops, is established to contain 23 species of soft-bodied, New World oonopine spiders that differ from those of Oonops Templeton and similar genera in having the male palpal bulb fused to the cymbium, and from those of Wanops Chamberlin and Ivie and Oonopoides Bryant in having shorter legs. Six specific names are transferred from Oonops to Noonops: O. floridanus (Chamberlin and Ivie) from Florida and Georgia (chosen as the type species), O. gertschi Chickering from the Bahama Islands (which is placed as a junior synonym of N. floridanus), O.furtivus Gertsch from Texas and Tamaulipas, O. sonora Gertsch and Davis from Arizona, California, Sonora, Baja California, and Baja California Sur, O. puebla Gertsch and Davis from Puebla, and O. chilapensis Chamberlin and Ivie from Guerrero. Males of N. sonora and females of N. furtivus are described for the first time; 18 new species are described: N. ocotillo, N. mortem, N. Joshua, N. skinner, N. coachella, and N. californicus from Arizona and southern California and N. willisi, N. mesa, N. naci, N. tarantula, N. miraflores, N. culiacan, N. taxquillo, N. chapul, N. beattyi, N. iviei, N. tonila, and N. minutus from Mexico.
Highlights
Brignolis recognition that few, if any, of the New World species are closely related to the European type species, Oonops pulcher Templeton, did little to solve the prob¬ lem; Gertsch (1977) subsequently assigned even a wider array of species to the genus
Most of the soft-bodied oonopines resemble other spiders in having a male palpal cymbium that is distinct from the palpal bulb itself
Among the generic names that have been used for New World soft-bodied taxa, this plesiomorphic condition occurs in the type species of Oonops, Oonopinus Simon, Heteroonops, Birabenella Grismado, Guaraguaoonops Brescovit et al, Predatoroonops Brescovit et al, and Neotrops Grismado and Ramirez
Summary
Diagnosis: Males differ from those of most soft-bodied New World oonopines in having the palpal bulb and cymbium fused, from those of Wanops in having a relatively short, subter¬ minal embolus, and from those of Oonopoides in lacking a hyaline conductor near the tip of the embolus; females have a distinct anterior receptaculum situated just anterior of a median, often T-shaped sclerotization. Male palp of normal size, not strongly sclerotized, right and left palps mirror images of each other, proximal segments, cymbium yellow; embolus light, prolateral excavation absent; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella basally; patella shorter than femur, not enlarged, without prolateral row of ridges, setae unmodified; tibia with three trichobothria AMNH PBI_OON 1756), Id, 29; High¬ lands Hammock State Park, N boundary, along county road, Apr. 6, 1966, Berlese, forest floor litter
