CEPHALOTHORAX: Carapace light yellow, shiny, finely reticulate. Sternum light yellow, lightly suffused with gray. Clypeus height 2. Chelicerae light yellow, not excavated; seta-tipped tubercles absent; promargin six teeth, retromargin five denticles. Cheliceral stridulatory organ ~11 striae, well spaced throughout. ABDOMEN: Uniformly light gray. LEGS: Light yellow; leg I total length: 2.64; leg III total length: 1.73; Tm I: 0.33, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis long and narrow, hook-shaped; dorsal tibial apophysis long and narrow; two retrolateral trichobothria and a dorsal one (
Fig. 546
). Cymbium rounded; glabrous depression absent (
Fig. 546
); dorsal cymbial tubercle wide with a few rugosity; ventral tubercle wide, rugose; prolateral notch shallow (
Fig. 547
). Paracymbium apical pocket long, anterior pocket short and small, posterior pocket absent (
Fig. 546
). Embolus tip rounded; basally with prong; Fickert’s gland absent; ventral lamella small rounded or absent; thumb reaching the embolus proper (
Fig. 548
). Embolus proper set apically, of equal part (
Fig. 548
). Anterior terminal apophysis wide, tip with short protrusions; posterior terminal apophysis small, with well sclerotized pointed tips, somewhat fused to the curved lamella characteristica with large basal prong (
Fig. 549
).
Female
:
Unknown.
Other material examined:
One other male taken with the
holotype
.
Distribution:
Southeastern
USA
.
Notes:
The male palp was slightly expanded, especially the embolus and radical division, therefore the position of some of the sclerites (
Fig. 546
) does not reflect their original position.
