Miltochrista producta (Černý, 2009)

(Figs 89–94, 134, 153)

Lyclene producta Černý in Černý & Pinratana, 2009, Moths of Thailand, 6: 87, pl. 19: figs 174a, 174b (Type locality: “N. Thailand, Chiang Mai, Doi Inthanon NP, 1416 m, 18°30’59’’N, 98°28’13’’E ”).

Type material examined. Holotype (Fig. 89): ♂, “N. Thailand | Chiang Mai-prov. | Doi Inthanon-NP, 1416m | 18°30’59’’N, 98°28’13’’ E | 6.–7.VI.2005 leg. K. | Cerný [recte: Černý]” / red label “HOLOTYPE | Lyclene | producta | Karel ČERNÝ, 2009 ” / “Genitalpräparat | Heterocera | Nr. 33.823 | Museum WITT München” (MWM / ZSM).

Additional material examined: series of specimens of both sexes from North, Northeast and South India (Assam, Meghalaya, West Bengal, Nagaland, Sikkim, Mizoram, Arunachal Pradesh, Uttarakhand, and Tamil Nadu), Nepal, Northern Thailand (Chiang Mai and Lampang Provinces) and Northern Vietnam (Tuyên Quang and Vĩnh Phúc Provinces) (NZCZSI, MWM / ZSM, CKC).

Diagnosis. The forewing length is 8.5–11.0 mm in males and 10.0– 11.5 mm in females. Although significantly variable in size, M. producta is easily distinguishable from the other congeners by the oblique, dash-shaped discal spot of the forewing and the medially angled medial transverse line. The male genital capsule of M. producta readily differs from the other species in the species-group by the proximally dilated and bilobate distal saccular process which is slender and unilobate in the similar congeners. The phallus and the vesica of M. producta are reminiscent of those of M. andamana but the phallus of the current species is longer and broader, and the vesica is markedly broader and two distal of its three cornuti are considerably shorter and narrower than the proximal one whereas the corresponding cornuti of M. andamana are only slightly shorter and narrower than the proximal one. The female genitalia of M. producta differ from the other taxa in the species-group by the shorter antrum (in proportion to the ovipositor length), and the more elongate corpus bursae bearing smaller spines posteriorly and covered with more robust spinules anteriorly.

Distribution. The species is currently known from Northeast India (Kirti & Singh 2016), Nepal (new record), Thailand (Černý & Pinratana 2009), Laos (Bucsek 2020), and Vietnam (new record).
