Systematics: N. americana is different from all species in Nearctic and Neotropic Regions in having the body densely covered with wax plates including the venter of the thorax (Kozár & Konczné Benedicty, 2001). Males of Newsteadia americana differs from N. floccosa in lacking lateral branches of dorsal midcranial ridge (vs. present), ridge fading before reaching postoccipital ridge (vs. bifurcating posteriorly); trochanter and femur unfused (fused on N. floccosa), number of tubular ducts smaller than on N. floccosa. (Vea, 2014)
Structure: Adult female is completely covered dorsally by heavy, definitely arranged plates of secretion, and at maturity secreting an ovisac equaling or sometimes exceeding the body in length. Adult male is small, elongate (Morrison, 1925). Total body length 1.63 mm. Antennae nearly 1.3 times total body length; body with few setae, locular pores absent, but simple minute pores, present sparsely throughout body. (Vea, 2014)
Biology: "Occurring in moist situations beneath rotten bark, on rotten logs, and in trash; possibly feeding on the roots of trees, shrubs or plants that had forced their way into the situation mentioned (Morrison, 1925)."
General Remarks: Original description and illustration by Morrison (1925). Redescription by Kozár (2004). Detailed description and illustrations of adult male in Vea (2014).
