Emended diagnosis. External morphology: Dorsal scutum rectangular. Prosoma slightly tuberculate, sometimes with an anterior hump. Eye mounds smooth. Area I divided by a median groove; I–II with small tubercles; III with two spines (just one spine in Auranus xerxes sp. nov.). Pedipalpal femur large; basal socket apex of tibia normal. Without tarsal process or scopula. Penis: Ventral plate present as a thin lamina parva, apically shaped as a calyx (Figs 2 A–D, 5A–C) and with two lateral flat projections directed ventrally (Figs 2 B, 5B–C). Truncus large and cylindrical, swollen distally, malleus surrounding completely the basis of the lamina parva. Chaetotaxy: MS A1– A3 flat and bifid, placed laterally on malleus; B ventrally on malleus, usually following the same row as MS A; MS C small, cylindrical and sharp, laterally on lamina parva; MS D reduced only to D1, dorsally on lamina parva; MS E1 close and similar in size and shape to MS C, E2 absent or when present, very large and located ventrally on malleus. Glans without dorsal process (one exception occurs in Auranus xerxes sp. nov.).
