The soft-bodied goblin spiders of the new genus Noonops (Araneae, Oonopidae)

NORMAN I. PLATNICK[1] AND LILY BERNIKER[2]

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. mortero, 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.

INTRODUCTION

Soft-bodied members of the subfamily Oonopinae are widely distributed in the New World, occurring from California east to Florida, Georgia, and the West Indies and south to Chile and Argentina, but have been far less studied than their hard-bodied relatives. Most of the classical work on these species was done by two arachnologists, Willis Gertsch and Arthur Chickering, who each described a wide array of species but assigned them, by default, to the type genus of the family, Oonops Templeton. As a result, well over 50 New World species have been placed, in the past, in Oonops. Almost 40 years ago, Brignoli (1974: 204) pointed out that “it is anything but certain that these forms are congeneric with the European Oonops” and concluded “it is fairly evident that a series of species belonging to different genera have certainly been described as Oonops.”

Unfortunately, Brignoli’s recognition that few, if any, of the New World species are actually closely related to the European type species, Oonops pulcher Templeton, did little to solve the problem; Gertsch (1977) subsequently assigned even a wider array of species to the genus. More recently, Platnick and Dupérré (2009) provided a detailed redescription of O. pulcher, based on topotypical specimens from Scotland, and began the process of breaking up the highly polyphyletic assemblage of New World species residing in Oonops, transferring five species to the circum-Caribbean genus Heteroonops Dalmas. Subsequently, Grismado and Ramírez (in press) have transferred four other species to a new genus that is widespread from Panama south to Argentina.

In the present paper, we continue this process by recognizing another new genus that occurs in the southern United States and Mexico. Most of the soft-bodied oonopines resemble other spiders in having a male palpal cymbium that is distinct from the palpal bulb itself (although the cymbium in these taxa is often much smaller than in typical spiders). Among the generic names that have been used for New World soft-bodied taxa, this plesiomorphic condition occurs in the type species of Oonops (see Platnick and Dupérré, 2009: figs. 38, 39), Oonopinus Simon (see Saaristo and Marusik, 2009: figs. 28, 29), Heteroonops (see Platnick and Dupérré, 2009: figs. 87, 88), Birabenella Grismado (see Grismado, 2010: fig. 33), Guaraguaoonops Brescovit et al. (see Brescovit et al., 2012a: figs. 20, 21), Predatoroonops Brescovit et al. (see Brescovit et al., 2012b: figs. 43–45), and Neotrops Grismado and Ramírez (see Grismado and Ramírez, in press: figs. 18B–D).

In the spiders discussed below, however, the male palpal bulb and cymbium are fully fused, as also occurs in many hard-bodied oonopids. The New World type species of Wanops Chamberlin and Ivie, and of Oonopoides Bryant, also show the fused condition (see Chamberlin and Ivie, 1938: fig. 2; cf. Bryant, 1940: fig. 6, which erroneously shows a distinct seam between the cymbium and bulb—the limits of the cymbium are actually indicated in Oonopoides only by the distribution of setae, not by a distinct seam). The species detailed below are clearly not members of either of those two genera. Wanops is an eyeless troglobite known only from Yucatán, whereas Oonopoides seems to be circum-Caribbean; members of both genera have longer legs than do those of the species assigned here to the new genus Noonops, as well as very different male genitalic conformations. Members of Oonopoides also seem to have relatively longer spinnerets (Dumitresco and Georgesco, 1983). A few of the males treated below retain some traces of the seam between the cymbium and bulb on one side of the palp (e.g., figs. 158, 167), but the other side is fully fused (e.g., figs. 156, 168).

Not all the North American species that have been assigned to Oonops in the past actually belong to Noonops, however. Indeed, several other groups seem to be represented, including one in which the palpal bulb and cymbium are not fused (Oonops chickeringi Brignoli from Mexico, for example, belongs to this group), one in which the embolus is terminal and whiplike (Oonops stylifer Gertsch from Texas is an example of this group, whose members may belong to Wanops), a third group, whose members probably belong to Oonopoides (Oonops mitchelli Gertsch from Mexico is an example of this group), and others (most of whose members are undescribed).

Interestingly, a few males of a different species have been collected in the San Francisco Bay area of California, considerably north of the Californian taxa described below. Surprisingly, the palps of those males do resemble those of true Oonops species from Europe, and we presume that these specimens represent an introduced population of one of the several European species that are closely related to O. pulcher.

As here limited, Noonops is primarily a North American genus, found across the far southern parts of the United States and in most of Mexico; it apparently does not occur in far southern Mexico (Oaxaca, Chiapas, or the Yucatán Peninsula) or in Central America. However, a population of the type species, N. floridanus (Chamberlin and Ivie), has been found on South Bimini in the Bahama Islands (where it was originally described under a different name), and a single male specimen that also appears to belong to this species was collected near Belém in northeastern Brazil. We suspect that both the Bahamian and Brazilian records represent human introductions, rather than natural parts of the range of N. floridanus, a hypothesis that may be falsified if future work on South American oonopines turns up additional species related to N. floridanus; we have been able to examine very few relevant samples from South America.

Although we suspect that the species detailed below form a monophyletic group, the evidence is not strong. The male palps are relatively simple, and (aside from the fusion of the cymbium and bulb) lack obvious specializations like the hyaline conductor found in Oonopoides (see Dumitresco and Georgesco, 1983), or the whiplike, terminal embolus found in Wanops (see Chamberlin and Ivie, 1938). The embolus varies widely, from a relatively small, simple structure (as in N. chilapensis, figs. 307–309) through somewhat wider structures with a few distal modifications (as in N. furtivus, figs. 97–105) to wide structures with highly complex tips (as in N. floridanus, figs. 37–57). Perhaps the best evidence for monophyly comes from the female genitalia, which have a distinct anterior receptaculum situated just anterior of a transverse sclerotized bar that separates the posterior receptaculum (figs. 95, 110), which typically has a sclerotized anterior portion. Among the other groups of New World oonopines, the female genitalia seem closest to those of Oonopoides, but a detailed comparison must await digestions of the full range of Oonopoides species, as that group seems to be large and circum-Caribbean in distribution. Interestingly, it appears that at least females of Noonops furtivus (Gertsch) may have the same kind of nail-shaped structure on the posterior end of the anterior receptaculum, fitting into a corresponding cone-shaped hole on the anterior end of the posterior receptaculum (fig. 110), that was first documented in hard-bodied oonopids by Burger et al. (2003). A similar system apparently exists in at least Heteroonops spinimanus (Simon), as indicated by Platnick and Dupérré (2009) and Burger (2011).

Species-level identification of Noonops specimens is not easy. Because of their small size (with total body lengths always under 2 mm and sometimes under 1 mm) and pale coloration, many of the relevant characters simply cannot be seen with ordinary dissecting microscopes. Accurate identifications require scanning electron micrographs of the male palps and endites, and compound microscopy of digested female genitalia; even compound microscopy is inadequate for study of the male palps. As a result, we have had to adopt a geographically based sampling strategy in choosing which specimens to scan or digest, and it is therefore entirely possible that some of the specimens recorded below that have not been scanned or digested are misidentified, and that some of the species recognized below are actually composites of two or more different species, the differences among which have not yet been detected. Ultimately, however, that is true for all species-level determinations, so we present here simply those hypotheses that have best survived the sampling strategy we have adopted, which has been to study in detail specimens from different localities, whenever potentially informative differences have been detected among them.

As a result, we are unable to present an identification key based on easily observable features; users will need to scan the palps and endites of newly discovered males, and digest the genitalia of newly discovered females, and compare those results to the diagnoses, descriptions, and figures presented below. For males, scans of the endites can help narrow down the range of species to be compared, as the taxa can be assigned to four (at least partly artificial) groups, based on the number of processes present on the anterior portion of the endites. Males can have three processes on each endite (N. mesa, beattyi), two processes on each endite (N. floridanus, ocotillo, sonora, skinner, coachella, californicus, naci, culiacan, chapul, puebla, iviei, minutus), a single process on each endite (N. mortero, taxquillo, chilapensis, tonila), or no processes at all (N. furtivus, joshua, willisi). Two species (N. tarantula, miraflores) are known only from females, and thus cannot be assigned to any of those groups. For females, digestions of the genitalia can help narrow down the range of species to be compared by focusing first on the shape of the anterior receptaculum, which can be bifid (N. floridanus), rounded (N. furtivus), rectangular (N. joshua, skinner, culiacan), elongated (N. sonora, mortero, californicus, tonila, minutus), triangular (N. ocotillo, coachella, tarantula, miraflores), or distally widened (N. mesa, naci, taxquillo, chapul). These female groupings may be close to monophyletic, but five species are known only from males (N. willisi, puebla, beattyi, chilapensis, iviei). Within each of the male and female groupings, geography provides the next best clues as to which species should be compared first.

Our methods follow those of Platnick and Dupérré (2009); only differences from the males (beyond the obvious lack of male endite modifications) are mentioned in the descriptions of females. Scans were sometimes taken from uncoated right male palps; in those cases, the images were flipped for consistency. All measurements are in mm. Species are discussed in geographic order, beginning in Florida and continuing west across the southern United States, and then east to west across the most northern tier of Mexican states, etc. High-resolution versions of the images, a sortable version of the geocoded locality data, and a distribution map for each species will be available on the goblin spider Planetary Biodiversity Inventory (PBI) project’s website (http://research.amnh.org/oonopidae). Users should note that the relatively small published images are merely avatars for the actual image files on the website, which can each be enlarged several times before pixelating; in many cases, the website hosts significantly more images for a given species than are presented here. Similarly, the maps made available on the website, via discoverlife.org, are more useful than printed versions would be, as each dot can be associated with the actual specimen data it represents.

Note: Chamberlin and Ivie (1935) reported the type locality as Gainesville (Alachua Co.), but the specimens labeled as the types by those authors were actually taken in Cocoa (Brevard Co.) instead; the species occurs at both localities.

Diagnosis: Males can easily be recognized by the relatively wide embolus with a subterminal rim (figs. 46–57), females by the bifid anterior receptaculum and wide posterior genitalic elements (figs. 88–96).

Male (PBI_OON 37991, figs. 1–57): Total length 1.47. Anterior portion of endites with two projections, distal one lobe shaped, directed anteromedially, proximal one sharp, posteromedially directed; serrula absent.

Synonymy: Given that Chickering (1969) studied Florida specimens of this distinctive species, it is odd that he later (1971) described specimens from the Bahamas, as Oonops gertschi, without even mentioning their obvious similarities. We have detected no significant, geographically consistent differences between the mainland and Bahamian populations (cf. figs. 43–45, 90, 95, 96, and other images available on the PBI website).

Noonops mortero, new species

Figures 153–163

Types: Male holotype, female allotype, and female paratype taken under rocks and thatch in a palm grove at Mortero Palms, south of Dos Cabezas, Anza-Borrego Desert State Park, San Diego, California (Mar. 26, 1991; D. Ubick), deposited in CAS (PBI_OON 35676).

Etymology: The specific name is a noun in apposition taken from the type locality.

Diagnosis: Males can easily be recognized by the enlarged, sharply bent basal process on the embolus (figs. 153–158), females by the long anterior receptaculum set on a strongly arched base (figs. 162, 163).

Male (PBI_OON 35676, figs. 153–160): Total length 1.39. Anterior portion of endites with single anterior process situated distally, directed anteriorly; serrula absent. Leg spination (leg III missing): tibia IV v0-0-2; metatarsus IV v0-0-2. Embolus with basal process greatly elongated.

Female (PBI_OON 35676, figs. 161–163): Total length 1.72. Leg spination: tibiae: III v0-0-1p; IV v0-0-2; metatarsi: III v0-0-1r; IV v0-0-2. Anterior receptaculum elongated, situated anterior of wide, recurved sclerotization.

Other Material Examined: One female taken in a Neotoma rodent nest on Magee Road, Tucson, Pima Co., Arizona, Nov. 10, 1960 (A. Aschwanden, AMNH PBI_OON 38489) was damaged during digestion, but may belong to this species, as it also seems to have an elongated anterior receptaculum but not more posteriorly situated, heavily sclerotized median elements. However, another damaged female taken in the same habitat has those median sclerotized elements and seems to belong to N. sonora instead, and thus possibly the median elements were simply lost during preparation of specimen 38489.

Distribution: San Diego Co., California (possibly east to Pima Co., Arizona).
