The goblin spider genus Oonopoides in North and Central America (Araneae, Oonopidae)

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

ABSTRACT

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.

INTRODUCTION

The New World soft-bodied members of the subfamily Oonopinae have posed a taxonomic conundrum for many years; over 50 New World species were described in the classical literature and assigned, without justification, to the type genus of the family, Oonops Templeton. As is often the fate of type genera, Oonops has thus served primarily as a wastebasket, in this case for a wide variety of New World taxa, none of which are actually congeneric with the European type species of the genus and its close relatives. Various participants in the goblin spider Planetary Biodiversity Inventory (PBI) project have made some progress in delimiting groups within this highly heterogeneous assemblage, transferring some of the misplaced species out of Oonops; five specific names were assigned to Heteroonops Dalmas by Platnick and Dupérré (2009), and several others have been placed in new genera by Grismado and Ramírez (in press) and Platnick and Berniker (2013).

Here we continue the process by considering the North and Central American species that we argue should be assigned to Oonopoides Bryant (1940). That genus was established for the species Oonopoides maxillaris Bryant, based on three males taken at Soledad, Cuba, but has not received much attention in the subsequent literature. Chickering (1951) added a second species, Oonopoides bryantae, based on a single male from Panama, but commented (1951: 226) that “It seems quite possible that O. bryantae sp. nov. is the male of Oonops reticulatus Petrunkevitch from Panama City.” Chickering (1970) subsequently confirmed that suggestion, synonymized the two names, and retained O. reticulatus in Oonops, thereby removing O. bryantae from Oonopoides. Oddly, Oonopoides was otherwise never mentioned in any of the long series of papers Chickering devoted to Central American and West Indian oonopids. Even though Chickering had ready access to the type specimens of Oonopoides, its members that he did describe were merely assigned to Oonops, along with many more distantly related species.

Brignoli (1974) was the first to point out the confusion rampant in the New World “Oonops,” making extensive comments in the context of dealing with four adult specimens from southern Mexico. One male and two females were described as Oonops chickeringi Brignoli, which he correctly placed as a close relative of Oonops tolucanus Gertsch and Davis (1942). Despite his recognition that the New World species were all likely to be misplaced, Brignoli assigned the species to Oonops. His male does resemble those of Oonops in having the cymbium and palpal bulb separate; had he studied males of any of the many Mexican species in which the cymbium and bulb are fused, he would likely have established a new genus for them instead. Brignoli’s description of O. chickeringi included the first detailed studies of the internal female genitalia of any of the New World oonopines, noting their complexity and predicting that they would supply information crucial to solving the generic-level puzzles.

Brignoli also studied another female, from Chiapas, that had internal genitalic structures very different from those of O. chickeringi, and he described that female as Oonopoides zullinii. At that time, no females were assigned to Oonopoides, and it isn’t clear why Brignoli considered his Mexican female to be congeneric with the males of the Cuban type species, O. maxillaris. He commented (1974: 207) that most of the characters mentioned by Bryant “are not entirely convincing” and admitted that he “assigned O. zullinii to this genus on account of a certain resemblance between the gnathocoxae and those of O. maxillaris and because this species cannot easily be included in any other Central American genus.” Bryant’s comments on the endites (i.e., gnathocoxae) of O. maxillaris were of course based on modifications that occur only in males and that are therefore not relevant to the placement of Brignoli’s female. Although we have not been able to examine Brignoli’s holotype, we have been able to study good samples from Chiapas, including males, that we consider to be conspecific with it, and we conclude that Brignoli’s placement of his female in Oonopoides was actually correct, despite having been based mostly on the luck of the draw!

More recently, Dumitresco and Georgesco (1983) described six additional species from Cuba, presenting a discussion of several characters that they suggested might serve to separate Oonopoides from Oonops, including the somewhat elongated spinnerets that had been mentioned by Bryant (1940) when she established the genus. Dumitresco and Georgesco presented detailed illustrations of the male and female genitalia, based on compound microscope preparations. Those illustrations are very useful, but are misleading in one important respect. Their figures of the male palps, like those of Bryant, indicate that the palpal cymbium and bulb are separated by a distinct seam, but they are actually fully fused (figs. 49, 50); the limits of the cymbium are indicated only by the distribution of setae, not by a seam. The same authors, publishing as Dumitrescu and Georgescu (1987), added a ninth species to the genus, from Venezuela; here again, their figures indicate that the palpal bulb and cymbium are separated by a seam.

All the males of Oonopoides that we have been able to study differ from those of Oonops in having the male palpal bulb fully fused with the cymbium. This includes the males of the type species, O. maxillaris; because this species has not yet been adequately documented in the literature, we present here images of the male palps and endites (figs. 1–11). These images are of specimens from the type series from Cienfuegos province, Cuba, and indicate that at least the male illustrated as O. maxillaris by Dumitresco and Georgesco (1983), which was taken in a cave in Matanzas province, Cuba, was misidentified by those authors, who did not examine the type series. In having the palpal bulb and cymbium fused, Oonopoides members resemble those of Noonops Platnick and Berniker (2013), rather than Oonops, and the two genera may well be sister groups. Noonops is primarily a North American group, whereas Oonopoides seems to be fully circum-Caribbean in distribution. Interestingly, though, they seem to be largely allopatric in Mexico, with Noonops found from Baja California east to Tamaulipas and south to Colima, Guerrero, and Puebla, and Oonopoides occurring mostly in areas further to the southeast (far southern Veracruz, Chiapas, and the Yucatán Peninsula). The only exception to this pattern detected to date is a single record of the Texas species Oonopoides secretus (Gertsch) from Tamaulipas.

As here limited, the monophyly of Oonopoides is well supported by male palpal morphology and male endite modifications; the hyaline conductor, bearing numerous tiny projections (figs. 51–53), is apparently unique to the genus, as are the ledgelike protrusions on the endites (e.g., figs. 19, 95, 106, 117, 128, 150, 172, 183). The male palpal bulbs also have a characteristic shape, being more constricted in the middle than they are at the proximal or distal ends (figs. 3, 5, 42, 44). The female genitalia show a wide range of structural forms, but often have ducts in the posterior receptaculum that are notably enlarged and three-dimensional. Such ducts are found also in the females from Texas that were identified as Noonops furtivus (Gertsch) by Platnick and Berniker (2013); those females, which have not been collected together with males, may thus be misidentified and may actually belong to an undescribed species of Oonopoides.

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 taken from uncoated right male palps, and the images were flipped for consistency. All measurements are in mm. Species are discussed in geographic order, beginning in Florida and continuing west to Texas and then south to Panama. To speed identifications, separate keys are presented to the species of North and Central America. High-resolution versions of the images, a sortable version of the geocoded locality data, and a distribution map for each species (with dots linked to the specimen data) will be available on the 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.

Oonopoides Bryant

Oonopoides Bryant, 1940: 265 (type species by original designation Oonopoides maxillaris Bryant).

Diagnosis: Males resemble those of Wanops Chamberlin and Ivie and Noonops Platnick and Berniker in having the palpal bulb fully fused to the cymbium, but differ from those of Wanops in having the embolus originating subterminally on the bulb and from those of Noonops in having a hyaline conductor, bearing numerous tiny projections, attached to the embolus (figs. 51–53).

Female genitalia with distinct anterior receptaculum situated on stalk; posterior receptaculum highly three-dimensional, often containing large ducts (figs. 89–92).

Distribution: Circum-Caribbean.

Unidentifiable Species: The holotype and paratypes of Oonops zeteki Chickering (1951), described from Isla Barro Colorado, Panama, were thought by Chickering to be adult females, as were three specimens later collected at Summit Gardens, Panama (see Chickering, 1970: 494). They are actually juveniles with leg spination indicating that they probably belong to Costarina Platnick and Dupérré (2011); apparently Chickering was unaware that juveniles of hard-bodied gamasomorphine groups lack the abdominal scuta found in adults. The name is here placed as a nomen dubium, as multiple species of Costarina occur at the type locality, and these juveniles cannot be identified at the species level.

Oonops balanus (misidentification): Chickering, 1971: 204 (some males from South Bimini only).

Oonops endicus (misidentification): Chickering, 1971: 209, figs. 24, 25 (females only).

Type: Male holotype taken on South Bimini, Bahama Islands (May 1951; W. Gertsch, M. Cazier), deposited in AMNH (PBI_OON 51291)

Etymology: The specific name is a patronym in honor of Wilton Ivie, who was the first person to collect specimens of Oonopoides in Florida.

Diagnosis: Males resemble those from Bimini described (but probably misidentified) as “Oonops balanus” by Chickering (1971: figs. 1–11), but have a longer, more evenly curved embolus (figs. 97, 100); females have a distally narrow anterior receptaculum and a heavily sclerotized, W-shaped anterior margin of the posterior receptaculum (figs. 102,103).

Male (PBI_OON 37348, figs. 93–101): Total length 1.83. Posterior eye row straight from front; ALE separated by their radius to diameter. Endites distally not excavated, anterior portion with single, rounded, protuberant ledge. Postepigastric scutum absent. Leg spination: femur IV d1-0-0; tibiae: III p0-0-1, v0-1p-2; IV d0-1-0, p1-0-1, v0-1p-2, r0-0-1; metatarsi: III v0-0-2; IV p1-0-1, v0-0-1p, r1-0-1. Embolus gently arched, with basal projection reduced to tiny spur no longer than tiny projections on hyaline conductor.

Female (PBI_OON 1719, figs. 102, 103): Total length 1.97. ALE separated by more than their diameter. Leg spination: femur III d1-0-0; tibiae: III p1-0-0, v1p-0-2, r1-0-0; IV p0-1-1, v0-1r-2; metatarsi: III v0-1p-2; IV p1-0-0, v0-1p-2, r0-0-1. Anterior receptaculum narrow, tubular, posterior receptaculum with heavily sclerotized, W-shaped anterior margin.
