( Figs. 48, 49 , 106 , 137 )

Type material. Holotype ( Figs. 48 , 106 ): ♂, “ Vietnam, Vinh Phuc Province, Tam Dao , N21°27.053' E105°38.798', 19.IX. 2014, 944 m, at light, G. Martin, BMNH (E) 2014-174”, slide BMNH (E) Arct. -6546 ♂ Volynkin (Coll. NHMUK) .

Paratypes: 1 ♀, same data as in the holotype (Coll. NHMUK) ; 2 ♀, Vietnam, Vinh Phuc Province: Tam Dao, roof of Hoang Lonh Hotel , N21°27.471' E105°38.679', 09.IX. 2014, 925 m, at light, G. Martin, BMNH (E) 2014- 174, slide BMNH (E) Arct. -6547 ♀ Volynkin (Coll. NHMUK) ; 1 ♂, 1 ♀, Vietnam sept, Tam Dao , 950 m, V.1990 leg. V. Kubáň (Coll. CKC).

Diagnosis. Length of forewing is 12.5–13 mm in males and 14–15.5 mm in females. The species is externally similar to N. hortensis fansipana , ssp. nov . due to its orange-reddish forewing pattern, but differs in its more yellowish coloration of the pattern elements, and the slightly more elongated male forewing. The male genitalia of N. martini sp. nov. are very characteristic and differ clearly from other species of the N. pusilla species-group in the very broad and long apical lobe of the valve and the small subapical saccular process; the aedeagus structure is similar to that of some other related species (e.g., N. thomaswitti sp. nov., N. fangae sp. nov., N. hortensis sp. nov.), but differ in the presence of the subbasal diverticulum of the vesica. The female genitalia of N. martini sp. nov. are most similar to those of N. karenkonis and N. hortensis sp. nov., but differ in the significantly longer antevaginal plate, the slightly broader ductus bursae, and the slightly larger signum.

Distribution. North Vietnam (Vinh Phuc Province).

Etymology. The new species’ name is dedicated to Mr. Geoff Martin (NHMUK, London), a collector of the holotype and three paratypes.
