Popis: Alaeho New Genus Description: Carapace moderately attenuated in front, margins serrated except the attenuated sides of the cephalic and the posterior end of the thorax. Fovea present. Eight eyes in two transverse rows, all clear except PME slightly whitish. AE shorter than the straight PE, slightly recurved in dorsal view to slightly procurved when viewed in front. Eye diameter: PME> ALE> AME> PLE. Eye separation: PME-PLE> AME-AME> PME-PME> AME-ALE. ALE slightly elliptical and very close to AME. PME elliptical, anteriorly diverging and posteriorly converging. PLE and ALE far apart, separated by almost the height of clypeus. Median ocular quadrangle narrower in front than behind, length as long as posterior width. Clypeus height small, less than one AME diameter. Sternum longer than wide, punctated, anterior end moderately concave medially to receive the labium base, laterals extended in between coxae to the venter of carapace, posterior end broad and blunt in between coxae IV. Labium as long as wide, widest posteriorly and apical margin cleft in the middle, apical end beyond midlength of maxillae. Maxillae longer than wide, outer lateral margin not excavated to house pedipalp, distal border almost entirely with scopulae. Chelicerae small and robust, swollen dorsally in the middle, constricted in the posterior one third, promargin bears no teeth except scopulae, retromargin with three teeth. Legs moderately long and slender, tibia III and IV with zero to two ventral spines, metatarsi III and IV bear zero or one ventral spine. Tarsi two-clawed, each claw with three or four teeth, claw tuft club. Leg formula 4123. Pedipalp with a porrect and pointed retrolateral tibial apophysis, as long as diameter of tibia, with a very long dorsal and two promarginal spines below midlength, and membranous conductor and median apophysis very minute. Abdomen depressed, dorsally and ventrally made up of shield-like plates (scutum) that terminate before the end of the abdomen, separated laterally or lateroventrally by a narrow membranous membrane. Anterior end of abdomen with a circular sclerotized structure housing the pedicel. Spinnerets all visible ventrally, anterior pair separated from each other basally by about one third diameter of spinneret. Posterior spinneret more cylindrical than the anterior pair and far apart, separated by one length of each spinneret. Type species: Alaeho linoi n. sp. Etymology: Derived from the expression of the collector in masculine form.
