03A7643CFFDB4F19FF3359A1FE5BA8E2.taxon	diagnosis	Diagnosis. Neischnocolus males differ from other Theraphosinae genera by the presence of one or two subconical processes on the retrolateral surface of the male palpal tibia (Figs 2 D, 4 D). Females differ from all other theraphosines by their spermathecae with paired ventral receptacles attached to a semi-circular to rectangular, sclerotized basal atrium. (Figs 7 D, 10 D).
