Japanagallia trifurcata View in CoL sp. nov.
( Figs 40–55 View FIGURES 40 – 55 ; 56)
Body length (including tegmina). ♂, 3.8–4.0 mm; ♀, 3.9 – 4.3 mm.
Holotype description.
Head and thorax (color). Ground color yellowish brown, generally paler in females. Head with pair of elliptical black spots dividing crown into three equal parts, and with small brown macula medially. Face with similar pattern as in J. gracilenta sp. nov.. Pronotum with black transverse band on anterior margin, longitudinal band at middle, two black spots on sides of middle line, and lemon yellow transverse band on posterior and both lateral margins. Scutellum black, with lateral margins yellow brown. Basal half of forewings black, distal half yellowish brown, venations yellowish brown. Legs yellowish.
Morphology. Body slender. Face across eyes distinctively wider than long; end of anteclypeus slightly expanded, and projected beyond genae and lorae. Scutellum as long as pronotum. Claval veins connected by two cross veins.
Male genitalia: Pygofer ( Fig. 43 View FIGURES 40 – 55 ), in lateral view, with small, scattered setae on distal half; posterior margin divided by posteroventral cleft with posterodorsal subtruncate section and rounded posteroventral lobe, spine-like. Valve broader than long, with front margin slightly concave, lateral margins sinuate; hind margin nearly straight, and narrower than anterior margin, lateral corners bluntly angled. Subgenital plates, elongate, triangular in ventral view, lateral margin slightly excavated, not fused to each other on basal part, with few scattered setae. Style ( Fig. 44 View FIGURES 40 – 55 ), with short and stout stem, apex with indistinctive prominence; inner arm slender, moderately elongated, exceeding beyond stem, apex truncate and expanded. Connective ( Fig. 45 View FIGURES 40 – 55 ), I-shaped. Aedeagus ( Figs 46–51 View FIGURES 40 – 55 ), in lateral view, bearing dorsal apodeme widened robustly, rather quadrangular; preatrium well developed, elongated, bearing long process, trifurcated apically, longer than shaft; and with small process at base; shaft bent dorsally, ventral margin with pair of long and slender processes directed apically; sub apex of shaft broadening towards truncate apex; gonopore apical on ventral margin.
Female genitalia. Seventh sternite wider than long, hind margin excavated medially, both lateroposterior corners nearly rounded, ovipositor clearly exceeding pygofer. First valvulae ( Fig. 52 View FIGURES 40 – 55 ), in lateral view, dorsally curved from base; ventral interlocking device on basiventral portion of shaft distinct; dorsolateral surface with reticulate sculptured area formed by oblique rows of scalelike processes ( Fig. 53 View FIGURES 40 – 55 ) on distal 2/3 of shaft; ventroapical region with more scalelike processes, dorsoapical and ventroapical margins pseudodentate; apex subacute ( Fig. 53 View FIGURES 40 – 55 ). Second valvulae ( Fig. 54 View FIGURES 40 – 55 ), in lateral view, curved dorsally from base, with broadest region at apical fifth; with dorsal hyaline area present, located nearly on median portion; dorsal prominence conspicuously pronounced; teeth on apical half of dorsal margin, positioned behind dorsal hyaline area, uniform, mostly subtriangular, not bearing denticles ( Fig. 55 View FIGURES 40 – 55 ); shaft apex subrounded ( Fig. 55 View FIGURES 40 – 55 ). Gonoplacs, in lateral view, shoelike, with basal half narrow and nearly paralleled between dorsal and ventral margins, dorsal margin suddenly broadened on apical 2/5 and then narrowing gradually toward rounded apex; surface with tiny spiniform processes and several setae along ventral margin.
Intraspecific variation (based on all examined specimens). Pronotal black pattern varies among specimens examined; black transverse band on anterior margin, longitudinal band at middle, and two black spots on sides of midline sometimes separated from each other, and sometimes fused to each other. In male, trifurcated apex of preatrium process varies within several specimens.

Distribution. China (Guizhou, and Yunnan Provinces, and Guangxi Autonomous Region).
Remarks. Japanagallia trifurcata sp. nov. resembles J. curvipenis Viraktamath et al. but differs in having a basal pair of slender processes on the aedeagal shaft, the trifurcated aedeagal ventral process longer than the shaft, and the inverted H-shaped connective; it is also similar to J. gracilenta sp. nov. and J. viraktamathi sp. nov., but differs from J. gracilenta sp. nov. in having shaft processes and ventral processes on the aedeagus, from J. viraktamathi sp. nov. by the serrated caudal margins of the pygofer, the trifurcated longer ventral process of the shaft, absence of spines on the dorsal apodeme, and also the differently shaped connective.
Etymology. The species epithet, trifurcata , is derived from the Latin words “ tri -” and “ furcate ”, and refers to the trifid aedeagal process.
