Note. In the original description of the species, Walker (1854) did not mention the sex and the number of specimens. In order to stabilise the nomenclature, we hereby designate the female syntype specimen deposited in the NHMUK collection and labeled as ‘Type’ as lectotype.

Diagnosis. The forewing length is 7.5–10.0 mm in males and 8.5–10.5 mm in females. Miltochrista humilis is reminiscent of M. nubilalis but differ in its larger size. The male genital capsule of M. humilis is very similar to Miltochrista postseriata ( Holloway, 2001) (illustrated by Holloway (2001) and Volynkin (2020)) but distinguished by the proximally broader valva with a shorter and somewhat distally downcurved distal saccular process, which is slightly upcurved in the congener. The vesicae of the two species are very similar but in M. humilis , the dorsal diverticulum bearing the larger cornutus is somewhat shorter than in M. postseriata . The female genitalia of M. humilis differ from M. postseriata (illustrated by Volynkin 2020) in the more anteriorly tapered antrum, and the shorter and thinner spines in the posterior section of the corpus bursae.

Distribution. The species is known from central and southern Myanmar, and Southern Thailand.
