Two new species of Cunaxa (Acari, Prostigmata, Cunaxidae) from South-East Asia with a world key to the genus

Abstract

Two new mite species of the family Cunaxidae (Acari, Prostigmata)—Cunaxa asiatica sp. nov. and C. smileyi sp. nov.—are described from Vietnam, based on females. Cunaxa asiatica sp. nov. is similar to C. doxa (Chaudri, 1980) in having the medial hysterosomal shield smooth and bearing setae c1–e1, c2, but differs from the latter by the presence of 1 sts, finger-like palpofemoral apophysis and smooth setae c1–e1 on basifemora IV (vs. 2 sts, uncinate palpofemoral apophysis and spiculate c1–e1 in C. doxa). Cunaxa smiley sp. nov. is similar to C. oblongostriata Kalúz and Ermilov, 2022 in having 4-4-4-4 sts on telofemora I–IV and 2 solenidia on genu II, but differs from the latter by the presence of 3-3-3-0 sts on basifemora I–IV, 1 asl and 5 sts on genu IV, and well developed medial hysterosomal shield (vs. basifemora I–IV setal formula of 3-3-3-1 sts, genu IV bearing 7 sts, and the hysterosomal medial shield absent in C. oblongostriata).
