Remarks
- Systematics: Kozár (2004) discussed the history and definition of Newsteadia, presenting also a diagnosis of the genus. The description of this genus was necessary to accomodate Transnewsteadia nepalensis which posessed distinctive characteristics of both Newsteadia and Nipponorthezia (Richard, 1990). The genus Newsteadia is characterised by having: (i) scape obviously larger than other antennal segments; (ii) middorsal wax plates protruding forwards; (iii) tubular ducts present on dorsum between the wax spines; and (iv) absence of spine bands within the ovisac band on the venter (Vea & Grimaldi, 2012). Adult male. Head with developed mid-cranial ridge and ventral midcranial ridge bifurcated. Compound eyes each with 30–75 ommatidia. Antennae each 9- or 10-segmented. Prosternum with a triangular sclerotized area. Metathorax with a small
metapostnotum in the middle. Fore wing shape rounded with costal thickening, subcosta, radius, cubitus anterior and anal fold. Hamulohalteres absent or present. Trochanter and femur fused or separate. Apex of aedeagus wide at tip. Body with minute pores but lacking locular pores. (Zheng, et al., 2023)
- Structure: Adult female of this genus is completely covered with depressed or flattened tufts or plates of secretion, much as in Orthezia. Ovisac is as long as the body. Larvae are similar to Orthezia, differing primarily in the possession of only four segmented antennae (Morrison, 1925). Adult male. Newsteadia is characterised by having: (i) head with developed mid-cranial ridge and ventral midcranial ridge bifurcated; (ii) compound eyes each with 30–75 ommatidia; (iii) antennae each 9 or 10 segmented, without minute pores; (iv) prosternum with a triangular sclerotized area, with well-sclerotized posterior margins; (v) metathorax with a small metapostnotum in the middle; (vi) wing shape rounded with subcostal and cubital ridges, and posterior edge of anal lobe forming a narrow fold for holding the hamulohalteres (if present); (vii) trochanter and femur fused or separate; (viii) apex of aedeagus widening at tip; and (ix) body completely lacking locular pores.(Zheng & Xing, 2021)
- Biology: There is no clear indication about host plant preferences. Members of this genus have been found in litter, in moss, under rocks, on roots of very different kinds of plants and plant communities (Kozár, 2004).
- General Remarks: Detailed description of the genus by Morrison (1925). Mamet (1947a) discussed the distribution of the genus. Redescription by Kozár (2004). Detailed description of the adult male in Vea, 2014.
