Nos.: AV2578 (male), AV2577 (female) (prepared by Volynkin) ; 1 male, Chiang Mai [Prov.], Chiang Dao, Doi Din Daeng , 525m, 19°19'26''N 98°55'26''E, 1.XII.2005, K.

Diagnosis. The forewing length is 8.0–8.5 mm in males and 10.0 mm in females. Miltochrista dagmarae anaptigmena ssp. n. ( Figs 3–6 ) differs from the nominate subspecies ( Figs 1, 2 ) in the somewhat narrower forewing having ante- and postmedial fasciae interrupted into rows of spots whereas the pattern of M. dagmarae dagmarae is reduced to the medial discal spot only. The male genital capsules of the two subspecies ( Figs 9–12 ) are similar but distal saccular process of M. dagmarae anaptigmena ssp. n. is somewhat more elongate and markedly slenderer than in the nominate subspecies. The phalli of the two subspecies are alike. The vesica of the new subspecies is similar to M. dagmarae dagmarae but bears basally narrower distal cornuti. In the female genitalia, M. dagmarae anaptigmena ssp. n. ( Fig. 16 ) is distinguished from the nominate subspecies ( Fig. 15 ) by the somewhat broader ductus bursae.

Distribution. The new subspecies is known from Northern, Eastern and Southeastern Thailand (Chiang Mai, Ubon Ratchatani, Nakhon Ratchasima, and Sakhon Nakhon Provinces).

Etymology. The subspecific epithet originates from the Greek ‘αναπτηγμένος’ meaning ‘developed’ and refers to the developed ante- and postmedial fasciae.
