Diagnosis

This new species resembles Phlugiolopsis damingshanis Bian, Shi & Chang, 2012 ( Fig. 9 ), but differs in male cercus with rectangular process on interno-ventral surface near middle area, apex truncate; female subgenital plate with apex roundly triangular.

Etymology

The specific epithet of the new species refers to the type locality Rongshui (Guangxi).

Description

BODY. Small.

HEAD. Fastigium verticis conical, apex rounded with longitudinal sulcus on dorsum. Eyes roughly globular, projecting forwards ( Fig. 3A ). Apical segment of maxillary palpus subequal to subapical one in length, apical area inflated.

THORAX. Pronotum feebly elongate backwards, anterior margin roughly straight, posterior margin rounded; lateral lobe longer than deep, humeral sinus absent ( Fig. 3B ).

TEGMEN. Tegmina short, terminals slightly surpassing posterior margin of pronotum, reaching middle area of third abdominal tergite, apices rounded ( Fig. 3B ). Hind wings absent.

LEGS. All femora without spines on ventral surfaces. Fore coxa with 1 spine; fore and middle tibiae each with 4 inner spines and 5 outer spines on ventral surfaces, respectively; fore tibial tympana open and ovoid on both inner and outer sides. Genicular lobes of hind femur with apices rounded; hind tibia with 1–2 spines on inner side and 3–4 spines on outer side of ventral surface as well as 28–29 inner spines and 31–33 outer spines on dorsal surface, bearing 2 pairs of ventral apical spurs and 1 pair of dorsal apical spurs.

MALE ABDOMEN. Tenth abdominal tergite with posterior margin faintly concave. Cercus stout on basal area, expanding inwards on dorsal surface, its apical area obtusely triangular; near middle area with rectangular projection on interno-ventral surface, apex truncate; apical half of cercus spinous, obviously incurved and upcurved, apex slightly acute ( Fig. 3C–D ). Subgenital plate with base broad, apical area narrowing; basal margin V-shaped concave, posterior margin rounded; styli short, conical, tips rounded, inserted at subapico-lateral angles of subgenital plate on ventral surface ( Fig. 3D ).

FEMALE ABDOMEN. Posterior margin of tenth abdominal tergite faintly concave. Cercus conic, tip acute. Ovipositor short, feebly upcurved; dorsal valvula slightly longer than ventral valvula, dorsal valvula with apex acute, ventral valvula with a terminal hook ( Fig. 3E ). Subgenital plate almost straight on basal margin; basal half rectangular, wide and short, lateral margins parallel; apical half triangular, apex rounded ( Fig. 3F ).

COLORATION. Body yellowish brown. Eyes black. Dorsum of head with 4 longitudinal dark brown stripes. Flagellum of antenna with sparse annulate black stripes, lamellar uplift on inner margin of antennal scrobe dark brown. Disc of pronotum with broad longitudinal brown stripe, posterior half slightly widened, lateral margins of two thirds anterior area of longitudinal stripe black. Genicular lobes dark brown; tarsi dark brown.

MEASUREMENTS (mm). Body length: ♂: 7.0–7.8, ♀: 6.4–7.5; length of pronotum: ♂: 3.2–3.5, ♀: 3.3– 3.5; length of tegmen: ♂: 1.3–1.5, ♀: 0.9–1.4; length of hind femur: ♂: 7.6–8.0, ♀: 7.4–9.0; length of ovipositor: 5.7–6.0.

Distribution

China (Guangxi).
