Etymology
. From the
type
locality. Noun in apposition.
Diagnosis
. Median guides wider than in
H
.
wisharti
(
Fig. 40
). Copulatory opening areas very strongly sclerotized, insemination ducts slightly bent, almost parallel (
Fig. 41
). Accessory glands at the junction between copulatory ducts and spermathecae.
Description
. Female
holotype
. Cephalothorax pear-shaped, pale yellow. Setae scarce, composed of white and light brown adpressed hairs and single brown bristles (
Fig. 34
). Carapace with median white guanine spots. Eye surroundings black. Thorax with median pale stripe. Abdomen long, with distinct pattern of white guanine spots on light background, sides brownish (
Fig. 34
). Spinnerets long, whitish. Clypeus pale yellow, narrow (about 21% of AME diameter), covered with white hairs, protruding bristles between AME (
Fig. 38
). Chelicerae light brown, with rugose frontal surfaces (
Fig. 38
), promargin and retromargin with 3 and 4 teeth, respectively (
Fig. 39
). Pedipalps pale yellow, darker distally. Endites and labium light brown with whitish distal halves. Sternum yellowish. Venter pale yellow with white guanine dots (
Fig. 36
). Legs pale yellow with darker bands on femora and metatarsi. Leg I the longest and more robust than others, ventral spination: tibia 2-2-2, metatarsus 2-2. Legs II more delicate, with similar colouration and ventral spination, but with a prolateral spine on tibiae. All femora with dorsal spines: femora first 1-1-2, the others 1-1-3. Epigyne with visible posterior pouch (
Fig. 40
), copulatory ducts elongated, spermathecae oval (
