Standard measurements of two examined specimens (ZIN 8995 and ZIN 9011): AW 49, 49; PW 70, 72; SB 33, 28; ASB 18, 22; PSB 23, 29; SD 41, 50; P-PL 7, 11; AP 28, 31;AM 37, -; AL 47, -; PL 54, 58; S 22, -; H 50, 54; D min 29, 32; D max 50, 52; V min 25, 32; V max 32, 40; pa 421, 430; pm 380, 387; pp 443, 446; Ip 1244, 1264; TaIIIL 131, 131; TaIIIW 15, 15; DS 32, 33; V 30, 28; NDV 62, 61.
Distribution. Australia, Malaysia, Taiwan, USA (California, South Carolina, Texas, Virginia) (Wharton & Hardcastle 1946; Stekolnikov 2021), and Paraguay (this study).
Hosts. Various species of birds (McClure 1987; Stekolnikov 2021) and, occasionally, Sylvilagus sp. (Lagomorpha: Leporidae) (Domrow & Lester 1985).
Material examined. 18 larvae (ZIN 8995–9003, 9005–9013) ex Hemitriccus margaritaceiventer Nos PG 261 and PG323, Coryphospingus cucullatus No PG 267, Coryphistera alaudina No PG 303, PARAGUAY: Teniente Agripino Enciso National Park, 31 August–3 September 2012.
Remarks. Records from Australia, Malaysia, and Taiwan can actually pertain to other species of Neoschoengastia Ewing, 1929, for example, Neoschoengastia solomonis Wharton and Hardcastle, 1946, which was described as a subspecies of N. americana (Stekolnikov 2021).
