WADOTES CHAMBERLIN

Wadotes Chamberlin, 1925: 120 . – Brignoli, 1983: 483; – Platnick, 1989: 426; – Platnick, 1993: 581; – Platnick, 1997: 672.

TYPE SPECIES: Wadotes dixiensis Chamberlin, 1925 , by original designation.

DIAGNOSIS: Wadotes can be easily recognized by the single, medially situated epigynal tooth of females (fig. 410), and by the presence of proximal cymbial apophyses in males (figs. 412–416). All Wadotes species examined have small AME, and three promarginal and two retromarginal cheliceral teeth (figs. 417, 418).

DESCRIPTION: See description of type species (below).

DISTRIBUTION: Eastern North America, from Nova Scotia to Georgia (map 20).

COMPOSITION: Twelve species were recognized in a recent revision ( Bennett, 1987). One of them, Wadotes primus Fox, 1937 , was transferred to the genus Coelotes by Wang et al. (2001) and is placed here as a member of Bifidocoelotes .

Wadotes dixiensis Chamberlin Figures 410–428

Wadotes dixiensis Chamberlin, 1925: 120 (male holotype from Lee Co., Alabama, deposited in MCZ, not found).

Wadotes bimucronatus: Muma, 1947: 5 , figs. 8, 9, 20, 21, 39, 40 (misidentification).

DIAGNOSIS: Females of this species can be distinguished by the broad spermathecal duct (fig. 411), and males by the shape of conductor dorsal apophysis (figs. 413, 414, 416).

DESCRIPTION: Total length about 5.00– 12.0. From front, anterior eye row slightly procurved, posterior row procurved; eye sizes and arrangements: AME smallest, about half ALE size, ALE slightly bigger than PLE, PME about 1.5 AME size; AME may be separated by roughly their diameter, AME­ALE about one­half AME diameter and subequal to ALE­PLE, PME­PLE about 1.5 PME diameter, PME­PME slightly short­ er than PME diameter, AME­PME about PME diameter. Clypeal height about twice AME diameter, covered with long, strong setae; chilum divided, hairless, short (fig. 417). Chelicerae with three promarginal and two retromarginal teeth (fig. 418). Labium about as long as wide, slightly notched distally. Length of female 1st leg patella + tibia shorter than carapace length.

Tarsal organ very small, situated close to distal end of tarsus, anterior of distalmost trichobothrium (figs. 420–422). Trachea simple (fig. 419). Apex of ALS with 2 major ampullate gland spigots (MAP), 13–20 piriform gland spigots in both sexes; PMS with 1 or 2 minor ampullate gland spigots (mAP) which may be more or less reduced and 37–38 aciniform gland spigots (AC) in both sexes, 2 cylindrical gland spigots (CY) in female; PLS with about 42–48 aciniform gland spigots in both sexes and 2 cylindrical gland spigots in female (figs. 423–428).

Female epigynum with single, median, broad epigynal tooth; atrium reduced to atrial slit; copulatory ducts short; spermathecal heads anterolaterally situated; spermathecal stalks long, enclosed in single, broad bursa; spermathecal bases small, bifid, laterally sit­ uated (figs. 410, 411). Male palp with one patellar apophyses, short; RTA long, occupying most of tibia, but not beyond tibia; lateral tibial apophysis transversely extend, formed small concavity on distal tibia; cymbial furrow moderately long, with distinct dorsal edge; tegular sclerite with prolateral apophysis; conductor long, strong; conductor dorsal apophysis with two dorsal and ventral teeth; conductor lamella large; embolus basal in origin, moderately long, linear; median apophysis spoonlike, with distal end not sharply pointed; tegular carina not apparent (figs. 412–416).
