Diagnosis

This species can be distinguished from known congeners by its straight, tapering embolus ( Fig. 9 B–D), medium sized, hook-shaped tibial apophysis ( Fig. 9 C, E) and the shape of the proximal tegular lobe ( Fig. 9 F). The male palp of this species is close to that of H.bovei Lucas, 1846 , H. ibericum Dalmas, 1920 and H. lepidum Dalmas, 1920 , but it differs in the shape proximal lobe of tegulum and tegular ledge.

Etymology

The speciFc epithet refers to the type locality.

COLOR AND BODY. Carapace dark brown. Chelicerae blackish brown. Labium yellowish brown with black edges. Dark brown bristles in vicinity of front eyes. Ocular region blackish brown, slightly elevated. PLEs surrounded by grey hairs. White and grey hairs intermingled on lateral and posterior sides of prosoma. Sternum oval shaped with tiny blackish dots. Prosoma longer than wide. First eye row slightly curved upward. Eye Feld short and wide occupying about one–third length of prosoma. Median ocular quadrangle much broader than long. Posterior margin truncated. Abdomen. Oval shaped, smaller and narrower than prosoma. Anterolateral dorsum with black blotches, posterior dorsum with pale white chevrons just above spinnerets ( Fig. 9 A). Venter pale yellow medially, blackish yellow laterally. Spinnerets yellow.

LEGS. All legs yellowish brown without any banding pattern.

PALP. Yellowish brown palp. Cymbium covered with dark brown hairs. Comparatively thin and straight embolus that tapers toward tip, and base of embolus emerging from under tegular ledge ( Fig. 9 B–D). Elongated bulbus. Tegulum with a proximal lobe, protruding posterolaterally beyond base of cymbium. Part of sperm duct clearly visible at distal end of tegulum. Short palpal tibia with medium sized and hook-shape tibial apophysis.

Female
