Diagnosis. Scape and pedicel yellow. First flagellomere brownish on lower 1/2–2/3. Scutellum light yellow on apical 1/3. Abdominal tergite 3 on basal 1/4 and tergites 4–5 on basal 1/3 with a pruinose band that is slightly interrupted at middle. Male face about 1.4 times as long as frons and facial ridge with 8–9 stout setae on lower 2/3. Fronto-orbital plate with 3–4 reclinate orbital setae. First flagellomere about 6 times as long as pedicel. Arista thickened on almost whole length. Gena short, 0.2 of eye height. Costal spine semi-erect and distinct. Abdominal tergite 3 with 1 pair of median marginal setae, male sternum 5 with rounded posterior lobes. Surstylus slender basally and pointed apically in posterior view.
Etymology. The name refers to the type locality (Zhanjiang) and should be treated as a Latin adjective.
Description. A small to medium-sized species. Body length 3.5–7.0 mm. Coloration. Head. Parafacial silvery white. Fronto-orbital plate concolorous with parafacial or with golden tinge. Frontal vitta yellow to brownish. Antenna mostly yellow, first flagellomere brownish on apical 1/2–2/3 (sometimes black at apex). Palpus yellow. Occiput silvery white. Thorax. Black in ground color, with gray pruinosity (appearing gray against a black ground color) except for 4 black vittae continuous across transverse suture, inner pair of vittae thin and outer pair broad. Scutellum black except light yellow on apical 1/3. Wing. Colorless and hyaline. Upper and lower calypteres white, semihyaline and lower one often with slight yellowish tinge. Halter yellow basally and brown apically. Tegula and basicosta black. Veins yellow. Legs black except femora slightly pollinose on anterior surface and pulvilli pale yellow. Abdomen black dorsally, brown laterally and ventrally. Basal 1/4 of tergite 3 and basal 1/3 of tergites 4 and 5 with pruinose band that is slightly interrupted at middle.
Male. Head. (Fig. 3) Eye bare. Frons at narrowest point about 0.38 head width. Frontal vitta a little wider anteriorly and slightly narrower than fronto-orbital plate. Fronto-orbital plate with 3–4 reclinate orbital setae (sometimes 1 or 2 comparatively fine) and some short hairs. Seven pairs of frontal setae slightly curved backward, lowermost seta situated at the level of arista. One pair of ocellar setae. Inner vertical seta about 1/2 of eye height in length. Outer vertical seta distinct, about 1/3 length of inner vertical seta. One pair of postocellar setae. One pair of paravertical setae. Occiput flat and white haired. Face concave and lower facial margin scarcely protruding beyond vibrissal angle. Parafacial bare, somewhat bulged at midlength and not narrowed downwards, subequal in width to first flagellomere. Facial ridge visible in lateral view and with 8–9 stout setae on lower 2/3. Vibrissa strong and situated at level of lower facial margin. Antenna long, first flagellomere blunt-tipped and about 6 times as long as pedicel. Arista bare, 0.7 times as long as first flagellomere and thickened on almost whole length. Second aristomere 4–5 times longer than wide. Gena height about 0.2 of eye height, with 2 strong subvibrissal setae and some long hairs. Maxillary palpus clavate, scarcely curved, with sparse black hairs; 1/2 length of first flagellomere. Prementum short and labellum medium-sized.
Thorax. Prosternum broad and with 3–4 hairs on each side. Postpronotum with 3 setae arranged in a line (innermost one fine and short). Three presutural and 3 postsutural acrostichal setae. Three presutural and 4 postsutural dorsocentral setae. One presutural and 3 postsutural intra-alar setae. Three postsutural supra-alar setae, first one strong. Two notopleural setae. Anepimeral setae short. Katepisternum with 3 strong setae and usually a fourth weak seta just behind and above anteriormost seta. Katepimeron bare. Scutellum (Fig. 7) semi-circular, bulged with a pair of discal setae on apical 1/3 and many semi-erect fine hairs dorsally. Basal scutellar setae well developed. Subapical scutellar setae parallel or convergent and 1.5–2.0 times as long as scutellum. Two pairs of fine lateral setae. One pair of weak and parallel apical setae, subequal in length to discal setae. Wing. (Fig. 6) Broad. Costal spine semi-erect and distinct. Second costal section (CS2) bare ventrally. Vein R4+5 basally with 2–3 hairs dorsally and 1–3 hairs ventrally. Proportion of costal sectors 2nd, 3rd and 4th nearly as 1: 2: 1. Cell r4+5 closed slightly before wing tip. Bend of vein M obtuse. Length of vein M from crossvein dm-cu to its bend about 1.4 times the distance between the bend and wing margin. Crossvein dm-cu straight and intersecting vein M halfway between crossvein r-m and bend. Legs. Tarsi shorter than tibia. Fore tibia without posterior setae, with a row each of anterodorsal and posterodorsal setae. Mid tibia with 2 strong anterodorsal, 2 posterodorsal (slightly shorter than anterodorsal) and 1 ventral setae. Hind tibia with a row each of anterodorsal and posterodorsal setae, 2–3 ventral setae, and 2 dorsal and 3 posterior setae apically. Claws and pulvilli shorter than 5th tarsomere.
Abdomen. Ovoid in shape and with dense short black hairs dorsally and laterally. Mid-dorsal depression on syntergite 1+2 reaching posterior margin. Syntergite 1+2 with 1 pair of indistinct lateral marginal setae and without median marginal setae. Tergite 3 with 1 pair of median marginal setae, 1 pair of lateral marginal setae and without median discal setae. Tergite 4 only with a row of 10–12 marginal setae. Tergite 5 with a row of discal setae and a row of weak marginal setae. Sternum 5 (Fig. 12) with posterior lobes somewhat rounded, with many fine hairs on inner apical margin as shown in the figures. Male terminalia. (Figs 10, 11) Cerci broad in posterior view, thick haired dorsally, and with a suture medially; slightly separated apically, apex slightly curved ventrally in lateral view. Surstylus straight and slender in lateral view, with 2 hook-like setulae latero-apically. Shape of epandrium, aedeagal apodeme, hypandrium, phallus, pregonite and postgonite as shown in figures.
Female. (Fig. 5) Very similar to male except as follows: vertex at narrowest point about 0.41 head width. Fronto-orbital plate with 2 proclinate orbital setae. Outer vertical seta well developed. The black hairs on frontoorbital plate slightly stronger than in male. First flagellomere slender and short, only about 5–6 times as long as pedicel. Facial ridge with setae a little sparser than in male. Claws and pulvilli subequal in length to 5th tarsomere.
Hosts. Unknown.
Remarks. This species is similar to K. conspersa Townsend, which is known from China and Japan (O’Hara et al. 2009). It is distinguished from K. conspersa by: shorter face (about 1.4 times as long as frons); facial ridge with only 8–9 setae on lower 2/3 (especially in male); first flagellomere shorter, about 6 times as long as pedicel; costal spine semi-erect and distinct; scape and pedicel yellow; apical 1/3 of scutellum light yellow, without any red or reddish; sternum 5 somewhat rounded without distinct inner bulge, basally concave medially; surstylus slender basally and pointed apically in posterior view.
We examined specimens of K. conspersa Townsend from Japan carefully and compared them with the type series of K. zhanjiangensis. The differences between these two related species are given in the key above, the diagnosis and description of the new species, and also in the figures (K. conspersa shown in Figs. 4, 8, 9, 13–15). Examined specimens of K. conspersa bear the following collection data: 13, Japan, Hyogo, Tanba, kusayama, 15.ix.1966, coll. K. Iwata; 13, 1Ƥ, Japan, Ryukyus, Nakanoshima (Takara Isl.), vii.1973, coll. K. Setoya; 1Ƥ, Japan, Kyushu, Fukuoka City, Mt.Aburayama, 15.vii.2008, coll. H. Shima (all on loan from Kyushu University Museum, Fukuoka, Japan).
