Diagnosis. The new species is characteristic by: General colour pale, head without distinct markings; male terminalia with a bell-shaped hammer, a pair of hook-shaped paraprocts and the triangular epiproct with a small membranous triangular median area.
Description. Adult. Body length 13.0–
14.3 mm
(
n
= 8), forewing length
11.5–12.5mm
, hindwing length 10.1–11.0 mm. Body color pale. Head pale, occiput elongated, compound eyes black. Biocellate. Antennae pale. Pronotum brownish and rectangular with paler rugosities, corners obtuse (
Fig. 3A
). Wings transparent, veins brownish. Legs generally pale, femur paler. Cerci pale brown.
Tergum 10 with a pair of brown subtriangular spines on posterior margin, apex sharp and separated far from each other, about in position of paraprocts. Epiproct triangular and divided by small membranous triangular area (
Fig. 3B
). Paraprocts hook-shaped, curved forward, pointed (
Fig. 3B
). Hammer bell-shaped, sometimes tapering to a nipple-like brown pigmented apex as shown in
Fig. 4D
in ventral view; apex swollen and curved upward dorsally in lateral view (
Figs 3C–D
,
4D–E
). Aedeagus generally membranous, sub-rectangular in ventral view, about 3X longer than wide, with a pair of basolateral lobes and meso-lateral processes, respectively. Caudally with a brown “bell-shaped” marking and a pair of “comb-shaped” marking (
Figs 4A–C
).
Female. Unknown.

Distribution.
China
(
Shaanxi
,
Sichuan
). The
types
in Qinling of
Shaanxi Province
were trapped near a wide stream. Elevation of habitats ranges from ca.
1500–1570 m
.
Etymology. The specific name refers to the
type
locality, Qinling Moutains.
Remarks. The new species is similar to
F. basomarginata
Chen, 2019
from
Sichuan
, by having similar color pattern and hammer. But it can be easily separated from
F. basomarginata
by the aedeagus apically with a brown “bell-shaped” marking, a pair of “comb-shaped” marking and lacking ventral lobes while the latter has heart-shaped lobe in ventral view and a pair of lateral spines at apex.
