Miltochrista kosterini ( Dubatolov & Bucsek, 2013)

( Figs 31–33 , 52, 53 , 63 )

Lyclene kosterini Dubatolov & Bucsek, 2013 , Tinea 22 (4): 284, figs 5, 20 (Type locality: “ Cambodia, Kampot Prov., Bokor Hill Station , h= 1030 m, 10º 37’37”N 104º01’33”E ”).

Type material examined. Holotype ( Figs 31 , 52 ): male, “ Cambodia, Kampot Prov., Bokor Hill Station , h = 1030 m, 10˚37’37”N, 104˚01’33” E, O.E. Kosterin leg., 18.VIII.2011 ” / handwritten red label “ Holotypus ♂ Lyclene kosterini Dubatolov et Bucsek ”, slide AV1712 Volynkin, ex preparation in sugar by Dubatolov (Coll. SZMN).

Paratypes: 3 females, with same data as in the holotype, slide AV2431 Volynkin (Coll. SZMN) .

Additional material examined. CAMBODIA: 18 males, 18 females, Cambodia, Kampot Prov., Bokor N.P., Hill Station , 1025 m, 10°37’N, 104°01E, 19–21.I.2006, leg. G. Csorba & G. Ronkay, slide MWM 33521 (male) Volynkin (Coll. MWM/ZSM) .

Diagnosis. Forewing length is 10 mm (wingspan 20 mm) in males and 11 mm (wingspan 22 mm) in females. The male specimens of M. kosterini can be easily distinguished from other members of the species-group by the darker forewing ground colour with more diffuse pattern and the intense grey suffusion in the subterminal area of hindwing. The female of M. kosterini is similar to those of M. stenovalva sp. n., M. adelfika sp. n. and M. kontumica , but differs by its slightly darker forewing ground colour and the presence of grey suffusion at the hindwing apex. The differences between the genitalia of both sexes of M. kosterini and its closest relative M. lavides sp. n. are listed in the ‘Diagnosis’ of the latter species.

Distribution. Cambodia (Kampot and Pursat Provinces) ( Dubatolov & Bucsek 2013; Bae et al. 2016).
