Diagnosis
Chilehexops can be distinguished from other diplurid genera by the absence of posterior median eyes, heavily sclerotized spermathecal trunks, a male palpal tibia nearly as long as the femur, and the absence of mating spurs, apophyses, and keels on the legs of adult males.
Description
Small mygalomorph spiders. Carapace with two (sometimes one or three) large erect setae just in front of fovea, single row of large erect setae extending posteriorly from ocular quadrangle along midline toward fovea, and several prominent erect setae on and in front of ocular quadrangle. Caput slightly elevated above thoracic region. Fovea shallow rounded depression to deep pit; slightly transverse or triangular. Six eyes in compact quadrangle groups, wider than long and slightly elevated; anterior median eyes well developed; anterior row strongly procurved; one pair of posterior eyes; central portion of quadrangle dark brown or black. Sternum longer than wide. Six indistinct, small, rounded sigilla, marginal. Labium about twice as wide as long, without cuspules. Chelicerae with one row of 6 to 13 teeth on promargin of fang furrow and 1 to 4 teeth on retrolateral margin. Maxillae without cuspules; maxillary lobe short, triangular; Serrula a broad band of sharp conical teeth. Pedipalp claw with single row of 11-14 teeth. Pedipalp of adult male with elongate patella and tibia; tibia nearly cylindrical, only slightly shorter than femur; tarsus with three to five terminal spines and two ventral rows of long slender macrosetae, one on each side of palpal organ; tarsus tip not extending much beyond base of palpal organ. Bulb of palpal organ elongate; gradually tapering into strongly curved embolus. Legs with three tarsal claws; single row of many teeth on each superior claw; row of two to four teeth attached directly to unpaired claw of tarsus I. Tarsi not pseudosegmented. Usually four (occasionally three or as many as nine) spines on tarsus I. No scopulae or metatarsal preening combs. Two rows of trichobothria on dorsal surface of each tibia; single row dorsally on each metatarsus and tarsus. Metatarsi III and IV with large number of very long spines. Male legs with several long suberect spines clustered on prolateral and ventral surface of tibia I. Anterior face of abdomen with many long strong setae that curve dorsoposteriorly with the contour of the abdomen. Anterior genital lip of female with transverse sclerotized plate visible in posteroventral view. Two heavily sclerotized spermathecal trunks, each with two sclerotized stalks, each stalk ending in unsclerotized bulb. Four spinnerets; median pair short, unsegmented, without crescent-shaped sclerite at base; lateral pair moderately long, with basal article longest, terminal article digitiform and equal to or slightly shorter than middle article.
