Diagnosis. The genus can be distinguished by the following combination of characters: legs long and slender, palpal tegulum ovoid with posterior lobe, embolus short, arising anteriorly; epigyne with large posterior pocket, copulatory openings located anteriorly, insemination ducts straight or wavy. Unlike in Adoxotoma leg spination not distinctive.

Description. Pluridentate spiders, 4–8 mm long. Transverse ocular fringe in males present ( H. minitabunda and H. occidentalis, see Wanless 1988), indistinct or missing (other species). Cephalothorax with gentle posterior slope and fovea located just behind PLE. Abdomen either elongate or ovoid, without scutum, with a mosaic of light and dark markings and translucent guanine, sometimes with stripes of pale hairs. Legs rather long and slender, in males first pair the longest and more hairy than in females, sometimes with femoral-patellar fringes. Tibia I with 3–7 proventrolateral and 3–6 retroventrolateral spines, metatarsus I with 2–4 pairs of ventrolateral ones. Leg formula in males: I–IV–II–III or I–IV–III–II, in females: IV–I–II–III or IV–I–III–II. Genitalia as described by Wanless (1988).
