Type material. Holotype ( Figs 15 , 28 ): male, “N. Vietnam, Mt. Fan-si-pan, N-Seite [N side], Cha-pa (= Sapa), 2800m, 22.15’ N 103.45 ’E, prim. Nebelwald [primary cloud forest], 26.III.1995, leg. et coll. Schintlmeister ”, slide ZSM Arct. 2019-954 Volynkin (Coll. MWM / ZSM).

Paratypes. N VIETNAM: 1 male with the same data as in the holotype (Coll. MWM / ZSM) ; 10 males, 2 females, 16[00]– 1800m, Mt. Fan-si-pan (West), Cha-pa, secondary forest, 22.20’ N 103.40 ’E, (agricultural landscape) IV.1995, leg. Sinyaev & local collectors, slides ZSM Arct. 2020-053 Volynkin (male), ZSM Arct. 2020-054 Volynkin (female) (Coll. MWM / ZSM) ; 25 males, Tonkin , Mt. Fan-si-pan (North), Cha-pa, cloud forest (22.15’N, 103.45’E), 2–4.III. 1995, 2240 m, leg. Dr. R . Brechlin (Coll. MWM / ZSM) .

Diagnosis. Forewing length is 19–20 mm in males (20 mm in the holotype) and 20.5– 21 mm in females. Ghoria synnefo sp. n. ( Figs 15, 16 ) is most similar externally to G. sinotibetica ( Figs 11, 12 ), but can be distinguished by its slightly larger size and brighter yellow edge of forewing costa. The male genital capsule of G. synnefo sp. n. ( Figs 28, 29 ) is most similar to that of G. albocinerea ( Figs 30, 31 ) due to its broad valva, but the distal saccular process is slightly more robust than in the allied species. Compared to that of G. mubupa sp. n. ( Fig. 26 ), the male genital capsule differs by the slightly tapered valva apex. Aedeagus of the new species differs from that of other relatives by the presence of a ventral dentate field on the carina. The vesica shape of G. synnefo sp. n. resembles that of G. mubupa sp. n., but the subbasal chamber bears a broad field of more robust spinules apically (whereas in G. mubupa sp. n. a similar field is situated laterally), the medial section of vesica is much shorter, and the distal diverticulum is slightly larger, bearing a broader cluster of more robust spines. The female genitalia of G. synnefo sp. n. ( Fig. 37 ) differ clearly from those of other members of the species-group by the globular, fully scobinated corpus bursae lacking signum (that is sack-like or elliptical and bears a large lateral signum bursae in the other related species). In addition, compared to those of G. albocinerea ( Fig. 38 ), the female genitalia of G. synnefo sp. n. differ by the shorter apophyses anteriores, narrower antrum, and the membranous anterior section of ductus bursae (in G. albocinerea that is covered with a shortly spinulose scobination).

Distribution. North Vietnam (Lào Cai Province).

Etymology. In Greek, ‘σύννεφο’ means ‘a cloud’. The specific epithet refers to the cloud forest habitats of the Mount Fan-si-pan where the new species was collected.
