SCOTOGNAPHA DALMAS

Scotognapha Dalmas, 1920: 119 (type species by original designation Pythonissa convexa Simon ).

DIAGNOSIS: Specimens of Scotognapha can be separated from other gnaphosids by the combined presence of a low, narrow, serrated keel on the cheliceral retromargin and a normal cheliceral tooth situated between the keel and the promarginal tooth row (figs. 2–4). The peculiar shape of the male palpal tegulum, which is extended posteriorly into a distinct prolateral lobe (as in figs. 19, 23, 27, 47) provides an excellent putative synapomorphy for the genus and is here predicted to occur in the as yet unknown males of S. paivai and S. costacalma .

DESCRIPTION: Total length 5.40 –14.05. Carapace oval in dorsal view, widest between coxae II and III, smoothly narrowed opposite palpi, light to dark brown, without darkened lateral margins; cephalic area slightly elevated; thoracic groove long, welldeveloped, longitudinal. From above, anterior eye row procurved, posterior row slightly recurved; from front, both rows slightly procurved. AME circular, dark; PME irregularly rectangular, light; other eyes oval, light; eyes almost subequal; AME separated by slightly less than their diameter, subcontiguous with ALE; PME usually separated by less than their diameter, by more than their diameter from PLE; lateral eyes of each side separated by more than their diameter; MOQ longer than wide, slightly wider in front than in back (fig. 1). Clypeal height more than twice AME diameter. Chelicerae with short, narrow, slightly serrated retromarginal keel, situated terminally, two or three promarginal teeth, and one intermediately situated tooth (figs. 2–4); retromarginal keel often appearing small, toothlike under light microscopy. Mouthparts and sternum dirty yellow to light brown; endites short, 1.5–2.0 times longer than wide, rounded, with oblique depression and weak distal scopula (fig. 5); labium twice as long as wide at middle (fig. 5); sternum oval, broad medially, with long setae at margins, short dark setae covering entire surface, rebordered, with short extensions to and between coxae.

Leg formula 4123. Typical leg spination pattern (only surfaces bearing spines listed): femora: I d1­1­0, p0­0­1; II d1­1­0, p0­0­1; III d1­0­1, p0­1­1, r0­1­1; IV d1­1­0, p0­0­ 1, r0­0­1; patellae: III p1­0­0, r0­1­0; IV r0­ 1­0; tibiae: III d2­0­1, p2­1­1, v2­2­2, r2­1­ 1; IV d1­0­0, p1­1­1, v2­2­2, r2­1­1; metatarsi: I v1­2­0; II v2­2­2; III d1­2­2, p1­1­1, v2­2­2, r1­1­1; IV d1­2­2, p1­1­1, v2­2­2, r1­ 1­1. Legs yellow­brown or light brown; tarsi lightly scopulate, with two dentate claws and claw tufts; trochanters not notched; metatarsal preening comb lacking; tibiae I, II of females ventrally without spines, of males with three pairs of spines; tarsi with two rows, metatarsi with single row of trichobothria, trichobothrial bases elevated, bearing 6–8 short, narrow ridges (figs. 7, 8); tarsal organ elevated, circular, smooth, with oval distal opening (fig. 6). Abdomen usually dirty yellow to brown with conspicuous anterior tuft of hairs, dorsum of some species with chevron pattern anteriorly, dark dots and stripes posteriorly; venter same color or lighter, with two closely spaced longitudinal rows of dark spots, few dark spots on sides; males with small anterior scutum. Carapace, abdomen, and legs covered by distally squamose, plumose setae bearing proximally 6–7 pairs of appendages originating from lateral surface (figs. 9, 10). Six spinnerets, anterior laterals large, cylindrical, separated by slightly more than their diameter, with two major ampullate gland spigots and five piriform gland spigots (fig. 13), posterior medians smallest, apically with minor ampullate and aciniform gland spigots, females with two posterior rows of cylindrical gland spigots; posterior laterals narrow, long, longer than ALS, with apical segment bearing aciniform gland spigots (fig. 14); posterior laterals typically strongly retracted into abdomen for 2/3 of their length, hence often appearing very short, even shorter than anterior laterals.

Male palp with prolateral portion of tegulum enormously extended posteriorly (figs. 16, 19, 23, 27, 31, 35, 39, 47); embolus fused with conductor, medially or prolaterally situated, directed anteriorly (figs. 17, 43, 51, 57, 61) or retrolaterally (figs. 19, 23, 27, 31, 35, 39, 47); median apophysis hooked; variously shaped terminal apophysis situated dorsally of embolus (figs. 19, 24, 28, 31, 47). Retrolateral tibial apophysis usually more or less conical, slightly curved at tip (figs. 20, 24, 28) or bifurcate ( S. teideensis only, figs. 15, 52–54). Epigynum with deep, rounded or elongated atrium, wide anteriorly and narrow to very narrow posteriorly, bearing wide anterior hood and raised median septum; copulatory openings situated medially (figs. 21, 25, 29, 33, 37, 41, 45, 49, 55, 59, 63, 65, 67); spermathecal ducts wide, short, with distinctive heads situated anteriorly, spermathecae consisting of posterior pair of large, globular or oval, widely separated receptacles (figs. 22, 26, 30, 34, 38, 42, 46, 50, 56, 60, 64, 66, 68).

Scotognapha convexa (Simon)

Figures 19–22

Pythonissa convexa Simon, 1883: 291 (male from Canary Islands, in MNHN, examined; see Note below).

Callilepis convexa: Simon, 1893: 382 .

Scotognapha convexa: Dalmas, 1920: 120 .

NOTE: Simon ( 1883) described Pythonissa convexa on the basis of a single female, in poor condition, collected by Verneau in the Canary Islands; no specific locality was mentioned, and there is no definitive indication in the original description as to whether the specimen was adult. In a later listing of specimens collected by Verneau in 1888, Simon ( 1889) recorded the species from named sites on three different islands (Grand Canary, Fuerteventura, and Lanzarote); again, however, no indication of the sex or maturity of any of those specimens was provided. When Dalmas ( 1920) first restudied the material in the Simon collection, he found one adult male and two juvenile females, and indicated that one of the juvenile females was actually the type specimen. He described the adult male, and it has seemed best to follow his decision and accept the choice of this adult male as representing Simon’s species. Unfortunately, there is no indication of an exact island of origin for that male, either. However, the only modern specimens matching that male are from Grand Canary, and we therefore assume that Grand Canary is the source, and type locality, of Simon’s species.

DIAGNOSIS: Males can easily be recognized by the long embolus bearing a wide, strongly curved tip (fig. 19) and the long, narrow terminal and median apophyses (fig. 20), females by the elongated, anteriorly narrowed epigynal atrium (fig. 21), as well as the short, wide heads of the anterolaterally directed spermathecal ducts (fig. 22).

MALE: Described by Dalmas ( 1920).

FEMALE: Total length 7.80. Carapace 3.71 long, 2.67 wide. Femur II 2.02 long. Eye siz­

es and interdistances: AME 0.17, ALE 0.17, PME 0.15, PLE 0.17; AME­AME 0.13, AME­ALE 0.04, PME­PME 0.06, PME­PLE 0.22, ALE­PLE 0.20; MOQ length 0.46, front width 0.43, back width 0.37. Leg spination: femur III d1­1­1; tibiae: II v0­0­1; III d1­0­1, p2­2­1, r1­1­1; IV r1­2­1; metatarsus I v2­2­0. Epigynal atrium elongated, narrowed anteriorly, with wide hood (fig. 21); heads of spermathecal ducts short, wide, directed anterolaterally, receptacles situated laterally (fig. 22).

MATERIAL EXAMINED: CANARY IS­ LANDS: no specific locality (Verneau, MNHN), 13, 2 juveniles . Grand Canary: Llanos de la Gorra, Mar. 23, 1997, under stones, elev. 100 m (J. Murphy, AMNH, JAM), 23, 1♀ .

DISTRIBUTION: Known only from Grand Canary. Records from Graciosa by Dalmas ( 1920), and from Lanzarote and Graciosa by Schmidt ( 1990), were based only on juveniles and are here rejected. The adult female recorded as this species by Schmidt ( 1990) from El Medano on Tenerife presumably be­

longs to S. medano instead, whereas the adult female similarly recorded from Gomera presumably belongs to S. canaricola . The male recorded as this species by Schmidt and Krause ( 1996) from Fuerteventura belongs to S. atomaria .

ETYMOLOGY: The specific name refers to the type locality.

DIAGNOSIS: This species seems closest to S. convexa , but can be separated in males by the wide, flat, apically untwisted embolus and wide median and terminal apophyses (figs. 23, 24), in females by the elongated and medially narrowed epigynal atrium (fig. 25), the narrow, anteriorly directed heads of the spermathecal ducts (fig. 26), and the posteriorly situated receptacles.

Scotognapha gravieri Dalmas, 1920: 121 (male holotype from ‘‘Syria’’, probably mislabeled, in MNHN, examined). NEW SYNONYMY.

Scotognapha convexa (misidentified): Schmidt and Krause, 1996: 266 (male from National Park El Jable, Fuerteventura).

DIAGNOSIS: Males can easily be recognized by the very long, narrow, apically arched embolus (which bears a small process medially), the large, spoon­shaped, and apically oval terminal apophysis and long, narrow median apophysis, and the long, anteriorly narrowed and apically slightly curved retrolateral tibial apophysis (figs. 27, 28), females by the wide, deep anterior portion and extremely narrow, shallow posterior portion of the epigynal atrium (fig. 29), as well as the slender heads of the spermathecal ducts (fig. 30).

NOTE: One of the males collected on Fuerteventura shows some variation in palpal structure: the embolus is slightly wider and more strongly bent anteriorly, and bears a larger medial process. Much larger samples would be needed to corroborate these slight differences as species­specific rather than individual variation.

MALE: Described by Dalmas ( 1920).

FEMALE: Total length 10.50. Carapace 4.25 long, 3.00 wide. Femur II 2.31 long. Eye siz­

es and interdistances: AME 0.14, ALE 0.17, PME 0.14, PLE 0.12; AME­AME 0.12, AME­ALE 0.03, PME­PME 0.06, PME­PLE 0.24, ALE­PLE 0.18; MOQ length 0.42, front width 0.36, back width 0.34. Leg spination: femora: III d1­1­2; IV d1­1­1, p0­1­ 1; patellae: III p1­1­0, r1­1­0; IV p1­0­0; tibiae: III d2­0­2; IV d1­1­0, p2­1­2; metatarsi: I v2­0­0; II v2­2­1.

Scotognapha paivai: Denis, 1963: 40 , figs. 7–9.

Scotognapha bewickei: Denis, 1963: 41 , figs. 10– 12.

DIAGNOSIS: Females resemble those of S. canaricola , but can be recognized by the extremely narrow, anteriorly rhomboidal epigynal atrium (fig. 65) and the large, long heads of the spermathecal ducts (fig. 66).

MALE: Unknown. The male from Tenerife described by Blackwall (1868: 407) could not be found in HDO, but was presumably misidentified.

FEMALE: Described by Blackwall ( 1864).

MATERIAL EXAMINED: SALVAGE IS­ LANDS: Great Salvage: ( HDO), 2♀ ( S. paivai syntypes) , 2♀ ( S. bewickei syntypes) ; 1983 (J. Murphy, AMNH), 1♀ .

DISTRIBUTION: Known only from the Salvage Islands (see Denis, 1963, for additional records); the juveniles from Tenerife record­

ed by Schmidt (1975c: 503, 504) are presumably misidentified.

SYNONYMY: No genitalic differences were detected among the female syntypes. Blackwall and Denis separated the two species only by differences in the size of the posterior lateral spinnerets: S. bewickei has very long spinnerets that are longer than the anterior laterals, with a long basal segment and a small apical segment, whereas S. paivai has a short basal segment on the posterior lateral spinnerets, which are shorter than the anterior laterals. The same character was probably used by Simon ( 1912) when he inferred that S. bewickei belonged to the Agelenidae rather than Gnaphosidae . Our study of the types and additional material indicates that all species of this genus have narrow, very long posterior lateral spinnerets (fig. 11) that are longer than the anterior laterals, but that the posterior laterals are most commonly retracted into the abdomen (at least in preserved specimens) and thus look quite short, even shorter than the anterior laterals.
