Raines, T. Phillips), male holotype(AMNH).Diagnosis.-The more slender, apically pointedmale flagellum of this species serves to separate itfrom A. lucifer. The presence of a pair of setae onabdominal tergite I separates this species from A.stygius. The two species may also be separated bythe femur IV length/depth ratio (4.8 in A. huitzmolotitlensisversus 6.0 in A. stygius). The presenceof ventrolateral lobes on the male flagellum readilyseparates this species from A. patei.Description.-Male holotype (length from distaledge of propeltidium to base of flagellum, 7.0 mm);light orangish brown.888990Figs. 88-92.-AgaslOschizomus huilzmolotillensis: 88, male flagellum, dorsal aspect; 89, male flagellum, lateral aspect; 90, maleflagellum, ventral aspect; 91, male pedipalp, lateral aspect; 92, male femur IV, lateral aspect.
