Name

Diagnosis

General coloration light yellow, antennae with flagellum black except the first flagellomere, pleura white conspicuously patterned with yellow, abdominal tergites with two black lateral stripes and one brown median stripe, ninth tergite with two rounded lobes, posterior margin of ninth tergite slightly concaved at base of lobes.

Description

Male (n=2): body length 9.6 mm, wing 11.0 mm, antenna 5.1 mm.
Nasus brown with brown setae, palpi black. Antennae relatively long, if bent backward extending to the first abdominal tergite, scape and pedicel yellow, flagellum 10-segmented, with the first flagellomere yellow, with second to tenth flagellomeres black and enlarged at base and apex, each flagellomere with black setae at base, subequal to the flagellomeres where they are found. Head yellow without occipital brand (Fig. 20). Pronotum entirely yellow. Prescutum yellow with three brown stripes, median one percurrent and expanded apically, lateral stripe straight and rounded apically, the area between lateral stripe and lateral border of prescutum suffused with brown (Fig. 21). Scutum light brown, each lobe with jet-black anterior border, median area of scutum yellow (Fig. 21). Scutellum yellowish brown. Postnotum light brown with white median stripe. Pleura white, variegated by yellow on anepisternum and katepisternum. Halters yellowish brown throughout. Legs with coxae and trochanters yellow; femora and tibiae yellow with brown tips; tarsi dark brown. Wings transparent, cells c and sc variegated with brown; stigma oval, dark brown; wing tip narrowed and slightly suffused with light brown. Cell r1 with five to six stigmal trichiae, cell m1 petiolate (Fig. 22).
Abdomen generally yellow, the first segment yellow with light brown tergite, tergites two to seven with a brown median stripe and two black lateral stripes, the median stripe expanded at hind border, tergite eight entirely brownish black; sternites two to seven with light brown median stripe, hypopygium chiefly yellowish brown. Male hypopygium (Figs 23, 24) with the ninth tergite having the median notch rounded and widened basally, separating the ninth tergite into two rounded black lobes, which densely covered with black spines, almost connected to each other (Fig. 25). Outer gonostylus lanceolate, basally widened and gradually narrowed to the end (Figs 23, 24, 26). Inner gonostylus with two black beaks, the dorsal side of inner gonostylus obviously extended (Fig. 27).
Aedeagal guide very similar to that of Nephrotoma liankangensis, with paramere not blunt apically, the dorsal margin slightly arched, the ventral and outer margins forming an obtuse angle (Fig. 28). Semen pump very similar to that of Nephrotoma liankangensis, with posterior immovable apodeme (PIA) not bent directed dorsad at the apex in lateral view (Fig. 30); compressor apodeme (CA) fan-shaped, broader than that of Nephrotoma liankangensis (Figs 29, 31), with median ridge slightly expanded in lateral view, which more degenerated than that of Nephrotoma liankangensis (Fig. 30); anterior immovable apodeme (AIA) more expanded than that of Nephrotoma liankangensis in lateral view (Fig. 30).
Female (n=3): body length 15.8 mm, wing 13.0 mm, antenna 2.5 mm.
The colouration of head, thorax and abdomen similar to those of male.
Antennae relatively short, scape and pedicel yellow, flagellum 10-segmented, each flagellomere cylindrical, gradually shorter, the basal two flagellomeres entirely yellow, three to ten flagellomeres yellowish brown with black at base.
Ovipositor (Figs 32, 33) very similar to that of Nephrotoma liankangensis, with ninth sternite obviously longer than that of Nephrotoma liankangensis (Fig. 34).
Vaginal apodeme widened at basal two fifths, the rest of vaginal apodeme tubular, parallel, acute apically (Fig. 34).
Spermatheca spherical, brown, well-sclerotized, with membranous extension truncate (Figs 35, 36).

Material examined

Holotype male. Pinned specimen. China: Yunnan Province, Kunming, Baofeng wetland park, 31 Aug. 2013, coll. Bin Zhang. Paratype. Pinned specimen. China: 1 male 3 females, same data as holotype.

Distribution

China (Yunnan).

Etymology

The specific epithet is based on the name of the related species, Nephrotoma liankangensis, with the Latin prefix ‘pseudo’, referring to the morphological similarity of the new species to Nephrotoma liankangensis.

Remarks

This new species is externally similar to Nephrotoma liankangensis by the colouration of head, thorax, abdomen and wings, and the shape of inner and outer gonostyli. It can be easily distinguished from the latter by antennae with the second to tenth flagellomeres black (the second to tenth flagellomeres yellow with basal enlargement black in Nephrotoma liankangensis), the occiput unpatterned (with brown median brand in Nephrotoma liankangensis as shown in Fig. 20), and the inner gonostylus with the dorsal margin obviously extended (just slightly extended in Nephrotoma liankangensis as shown in Figs 8, 9). The new species is also similar to Nephrotoma liankangensis in some internal reproductive organs, but differs from the latter in the female vaginal apodeme widened at basal two fifths, tubular and parallel at apical three fifths (vaginal apodeme widened at basal half and gradually tapered to the end in Nephrotoma liankangensis as shown in Fig. 17), the spermatheca laterally with membranous extension truncate (with membranous extension angular in Nephrotoma liankangensis as shown in Fig. 18), the male aedeagal guide with paramere not blunt apically (apically blunt in Nephrotoma liankangensis as shown in Fig. 10), the semen pump with posterior immovable apodeme not dorsally bent (dorsally bent in Nephrotoma liankangensis as shown in Fig. 13), and compressor apodeme with median ridge slightly expanded in lateral view (median ridge obviously more expanded than that of Nephrotoma pseudoliankangensis in Nephrotoma liankangensis as shown in Fig. 13).
