Homoneura (Homoneura) spectabilis sp. nov.

( Figs 92−98 View FIGURES 92–98 , 99−103 View FIGURES 99–103 )

Description. MALE. Body length 5.4−5.7 mm, wing length 5.2−5.5mm.

Head ( Figs 92−93 View FIGURES 92–98 ) yellow. Ocellar setae longer than anterior fronto-orbital setae. Gena about 1/6 height of eye. Antenna yellow, 1st flagellomere about 1.9 times longer than high; arista blackish brown, with longest ray as long as 1/2 height of 1st flagellomere. Proboscis and palpus yellow.

Thorax ( Fig. 94 View FIGURES 92–98 ) brown, postpronotum yellow. Mesonotum with 0+3 dorsocentral setae (anteriormost dorsocentral setae behind the transversal suture), acrostichal setulae in 6 rows and a pair of prescutellar setae longer than 1st post-sutural dorsocentral setae. Legs mostly yellow, all trasomers 3−5 brown. Fore femur with 5 posterodorsal setae, 4 posteroventral setae and ctenidium with 11−14 short setae; fore tibia with 1 long preapical anterodorsal seta and 1 short apicoventral seta. Mid femur with 3 anterior setae and 1 short apicoposterior seta; mid tibia with 1 strong preapical anterodorsal seta and 2 strong apicoventral setae. Hind femur with 1 preapical anterodorsal seta; hind tibia with 1 long preapical anterodorsal seta and 1 short apicoventral seta. Wing ( Fig. 98 View FIGURES 92–98 ) yellow, brown apical spots on R 2+3, R 4+5 and M 1 separated each other; a brown median spot on R 4+5 separate from brown cloud on dm-cu; subcostal cell pale yellow; 2nd (between R 1 and R 2+3), 3rd (between R 2+3 and R 4+5) and 4th (between R 4+5 and M 1) sections in proportion of 4.6:1.3:1; r-m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.6; ultimate sections of CuA 1 about 1/9. Halter pale yellow.

Abdomen ( Figs 95−96 View FIGURES 92–98 ) yellow. Male genitalia ( Figs 97 View FIGURES 92–98 , 99−103 View FIGURES 99–103 ): syntergosternite 7+8 circular (but sternal part trapezoid); epandrium broad with three pairs of long setae in lateral view; surstylus pale brown, with a hyaline rectangular area and some marginal setulae in lateral view; hypandrium H–shaped; pregonite flat and hyaline, blunt at apex; phallus with a pair of brown triangular blunt subapical processes in ventral view and a small sharp lateral process in lateral view; phallapodeme longer than phallus.

FEMALE. Unknown.

Type material. CHINA, Shaanxi Province: Holotype ♂ ( IMAU), Foping County, Daguping , 1329.2 m, 24. VIII. 2014, Xiumei Lu . Paratypes ( IMAU): 2♂♂, data same as the holotype .

Remarks. The new species is similar to Homoneura (Homoneura) platimarginata sp. nov., but the latter has the following features: the surstylus being broad and margined apically in lateral view, the pregonite and postgonite being sharp at apex in lateral view, and the phallus having sharp dorsal and lateral processes in lateral view.

Etymology. Latin, spectabilis , meaning marvelous, referring to very special phallic complex; a feminine adjective.
