(Fig. 1)
Description. Male. Body small. Fastigium verticis conical, apex rounded, furrowed on dorsal surface. Eyes oval, slightly protruding forward. Apical segment of maxillary palpus slightly longer than subapical one, apex slightly swollen. Pronotum slightly elongate backwards, anterior margin almost straight, posterior margin rounded; lateral lobe longer than high, without humeral sinus. Most parts of the tegmina concealed beneath pronotum, terminals reaching middle area of third abdominal tergite, apices rounded; hind wings absent.
All femora unarmed on ventral surfaces. Fore coxa with 1 spine; fore tibia with 5 internal spines and 6 external spines on ventral surface; tibial tympana open on both sides, elongate to oval. Middle tibia with 5 spines on inner margin and 6 spines on outer margin of ventral surface. Genicular lobes of hind femur with apices rounded; hind tibia with 21–25 spines on both sides of dorsal surfaces separately, bearing 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.
Tenth abdominal tergite with posterior margin slightly concave. Cercus comparatively long, stout at base, narrowing towards tip; dorsal surface with a long and narrow lamellar expansion near base, basal half of lamellar expansion slightly curved dorsad on internal margin (Fig. 1C), apex with a rounded angular process (Fig. 1D); near middle area with a rounded angular process on ventral surface (Fig. 1E); apical half of cercus divided into dorsal and ventral branches, dorsal branch short, curved inward and dorsad, apex rounded; ventral branch slightly longer, recurved, apex rounded. Subgenital plate with base broad, slightly concave on basal margin, apical area narrowing; subapex convex dorsad, apex curved ventrad, posterior margin truncate (Fig. 1E); styli comparatively long, inserted on ventral surface of subapex of subgenital plate.
Female. Appearance is similar to male. Lateral surface of eighth abdominal tergite on apical area with a short conical projection separately (Fig. 1F). Lateral surface of ninth abdominal tergite expanded backwards. Posterior margin of tenth abdominal tergite split (Fig. 1G). Epiproct triangular, slightly concave at apex. Cercus conical, apex acute. Ovipositor (Fig. 1I, J) short, gently curved upwards; dorsal and ventral margins smooth, dorsal valvula slightly longer than ventral one, dorsal valvula with apex acute, apex of ventral valvula hook-shaped. Subgenital plate roughly circular, posterior margin lightly concave (Fig. 1F); lateral margins arc-shaped concave near base (Fig. 1H).
Coloration. Body yellowish brown. Eyes reddish brown. Dorsum of head with 4 longitudinal dark brown stripes. Scape and pedicel brown, lamellar uplift on internal margin of antennal socket blackish brown, flagellum with annulate black annulate stripes. Disc of pronotum with a broad longitudinal brown stripe, posterior half slightly expanded, two thirds anterior area of longitudinal stripe blackish brown on lateral margins. Exposing area of tegmen brownish. With pinniform brown stripes on outer surface of hind femur; genicular lobes black; tibia with spines brown. Tarsi blackish brown. Abdomen dark brown. Male cercus yellowish white.

Discussion. This new species can be distinguished from known species of the genus Phlugiolopsis by: male cercus comparatively long, dorsal surface with a long and narrow lamellar expansion near base, basal half of lamellar expansion slightly curved dorsad on internal margin, apex with a rounded angular process; apical half of cercus divided into dorsal and ventral branches, dorsal branch short, curved inward and dorsad, apex rounded; ventral branch slightly longer, recurved, apex rounded. Lateral surface of female eighth abdominal tergite on apical area with a short conical projection separately.
Etymology. The name of new species is derived from the furcate of male cercus, from Latin ‘furc-’ (furcate) and ‘caud-’ (caudatus).
Distribution. China (Yunnan)
