description: Phlugiolopsis (Uncinata) angustimarginis Bian & Shi, sp. nov.
(Figure 4)
Material examined. Holotype, 6, Huguo, Longchuan, Yunnan, China, 10 August, 2013, coll. Jiao Jiao. Paratypes: 1 6, same data as holotype but 9 August, 2013, coll. Guanglin Xie. Other specimens (conserved in alcohol): 2 6, same data as holotype.
Description. Male. Yellowish brown. Head. Face yellowish brown. Internal margin of antennal socket, scape and pedicel blackish brown. Fastigium verticis conical, apex obtusely rounded, in the centre a shallow furrow is present; dorsal surface of head with 4 distinct darkish brown stripes (Figure 4A): outer stripes extending to internal margin of antennal socket, which continued along the pronotum, medial stripes fused in fastigium verticis. Eyes round-oval, lighter brown. Apical segments of maxillary palpi slightly longer than subapical ones, apices slightly inflated; the apices of maxillary palpi slightly darker brown.
Thorax. The outer stripes of the head continued to the apical area of metazona, area between them with a blackish brown stripe; anterior margin of pronotum slightly straight, posterior margin narrowly rounded; the lateral lobe longer than high (Figure 4B).
Tegmina. Tegmina surpassing the pronotum, the posterior margin reaching the middle area of third abdominal tergite (Figure 4B); around the tegmina yellowish brown. Hind wings absent.
Legs. All femora without ventral spines. Fore coxae with a small spine. Fore tibiae with 4 internal and 5 external spines on ventral margin, apices with 1 pair of ventral spines. Middle tibiae with 4 pairs of spines and 1 pair of apical spines. Genicular lobes of hind femora with obtuse apices, black; tibiae with 25–25 internal spines and 23–25 external spines on dorsal surface, apices with 1 pair of dorsal spines and 2 pairs of ventral spines, darkish brown.
Abdomen. Tergites and sternites black. Tenth abdominal tergite with arched concavity; epiproct tongueshaped, distinctly invaginated dorsally. Cerci. Yellow. Dorsal internal margin of basal half slightly expanded, (Figure 4C), ventral internal margin with 1 obviously longer digitiform lobe (Figure 4C), the apical pointed insides, apices obtusely rounded. Apical half of cerci spine-shaped, slightly incurved, apices obtuse (Figure 4F). Subgenital plate with base broad, gradually narrowing, basal margin nearly straight, with 1 V-shaped membranous area; subapical area slightly trapezoidal, projecting, posterior margin truncate (Figure 4F). Styli conical, apices obtuse, inserted on the subapex of subgenital plate.
Female. Unknown.
Measurements. Body length: ♂ 8.0– 8.5 mm, ♀ 7.4 mm; length of pronotum: ♂ 4.4–4.6 mm, ♀ 3.4 mm; length of tegmina: ♂ 2.8–3.0 mm, ♀ 0.8 mm; length of hind femora: ♂ 8.3–8.8 mm, ♀ 8.5 mm; length of ovipositor: 4.6 mm.
Distribution. CHINA (Yunnan).
Diagnosis. The new species is very similar to Phlugiolopsis (Uncinata) mistshenkoi (Gorochov, 1993), but differs from the latter in: basal area of male cerci with slightly expanded dorsal margin and 1 longer digitiform ventral lobe, subapical area of subgenital plate trapezoid projecting. In Phlugiolopsis (Uncinata) mistshenkoi (Gorochov, 1993) male, the cerci have keel-like round dorsal lobe and wide curved internal lobe, the apices of internal lobe nearly triangular.
Etymology. The specific name ‘ angustimarginis ’ is derived from Latin word ‘ angust ’ (=narrow) and ‘ margin ’ (=margin). It refers to the dorsal margin of male cerci slightly expanded.
