Diagnosis. ( Table 13 ) Entirely dark brown to black; stigma pale, often indistinct; eyes bare; palpal segment 3 sensory pit as deep as wide, broadening internally on female (as in Fig. 32 L . foulki ); hind tibial comb with four spines; claw without basal tooth. Female: antenna with 11 flagellomeres; clypeus with four setae, median pair about as far apart from each other as from corresponding lateral setae; hind tarsomere 3 ~1.5× longer than 5; two ovoid spermathecae, vestigial third absent; cerci>3× longer than wide (as in Fig. 1 ). Male: tergite 9 with distal shoulders abruptly narrowed to base of adjacent apicolateral processes; aedeagal sclerites longer than any paramere sclerite,>0.3 as long as gonocoxite; strongly sclerotized lobe in median portion of tergite 9 dorsal to aedeagus. Distribution. California , Arizona . Adult behavior. Females and males have been collected on the face of and swarming around a human, but not biting ( Wirth and Atchley 1973 ); and Mullens and Dada (1992a) collected L . belkini from domestic rabbit ( Oryctolagus cuniculus ), Japanese quail ( Coturnix japonica ), and bighorn sheep ( Ovis canadensis nelsoni Merriam , Bovidae ).
