Male. Body length: 12.0 mm, humeral width: 4.5–5.0 mm (2 individuals); holotype ( Figs 27–43 ), body length: 12.0 mm, humeral width: 5.0 mm. Body reddish brown, antennomeres V–X (except for apex) and antennomere XI yellowish brown; antennomeres III–X dark brown apically; prothorax (except for prosternum), most parts of elytra, sides of meso- and metaventrite and urosternite I (except for base) black; urosternites IV–V yellowish brown ( Figs 27–29 ). FIGURES 27–29. Paragnia tiani sp. nov. , holotype, male. Habitus: 27. dorsal view; 28. ventral view; 29. lateral view. Scale bar: 5 mm. Frons sparsely covered with short grayish-white and black setae ( Fig. 30 ). Scape, pedicel and middle of antennomere XI sparsely covered with short black setae; apical half of antennomere IV with moderately dense short black setae, antennomeres IV–IX with several long black setae ventrally, scape, pedicel and base of antennomere III with sparse short grayish-white setae, basal half of antennomere IV with moderately dense short light-yellow setae ( Figs 27–29 ). Prothorax with a yellow setal band at laterobasal half ( Figs 27, 29 ). Each elytron with a longitudinal yellow setal band on the basal 1/3 close to the suture and an irregular yellow setal spot on inner margin of apex ( Fig. 27 ). Prosternum and mesoventrite sparsely covered with short grayish-white setae ( Fig. 28 ). FIGURES 30–32. Paragnia tiani sp. nov. , holotype, male. 30. Head, frontal view; 31. prothorax, dorsal view; 32. right hind wing, dorsal view (A: anal, C u : cubital, MP: medial posterior, MS: medial spur, r: radial). Scale bars: 2 mm. Antennae 1.4 times as long as body, antennal formula (ratio) based on length of antennomere III: scape= 0.60, pedicel= 0.10, IV= 0.87, V= 0.53, VI= 0.47, VII= 0.40, VIII= 0.35, IX= 0.32, X= 0.28, XI= 0.38. Inner side of antennomeres V–IX slightly projected near base ( Figs 27–28 ). Elytra 2 times as long as wide at base. MP 3+4 and MP 4 veins of hind wing far from each other ( Fig. 32 ). Margin of urosternite V slightly notched medially ( Fig. 28 ). Male terminalia. Tergite VIII ( Figs 33–34 ) sub-semicircle, with a feebly triangular projection at apical middle. Stem of spiculum gastrale more than 2 times as long as branches ( Figs 35–37 ), curved near basal 1/ 3 in lateral view ( Fig. 36 ). Tegmen ( Figs 38–40 ) shorter than penis, dorsum of parameres sparsely covered with short fine brown setae and several long thick brown setae near base and apex, phallobase expanded near the apical 1/3 and gradually tapered to base, then curved near the basal 1/ 3 in lateral view ( Fig. 39 ), tegminal struts distinctly expanded towards inside near apex ( Figs 38, 40 ). Venter of dorsal struts of penis distinctly constricted near apical 1/ 4 in lateral view ( Fig. 42 ). Female. Unknown. Diagnosis. Males of this new species can be distinguished from Paragnia fulvomaculata by the prothorax with a yellow setal band on the laterobasal half (without yellow setal band in P . fulvomaculata ); the long yellow setal bands on basal middle and basal margin of elytra (short in P . fulvomaculata ); each elytron with a yellow setal band on the basal 1/3 close to suture (with several yellow setal spots in P . fulvomaculata ), with a yellow setal spot on inner margin of apex (with sparse short light yellow hairs in P . fulvomaculata ); antennae short (long in P . fulvomaculata ), antennomeres III–IV thicker (thin in P . fulvomaculata ); CuA 2 vein of hind wing short (long in P . fulvomaculata ), the distance between MP 3+4 and MP 4 veins long (short in P . fulvomaculata ), sr vein missing (with sr vein in P . fulvomaculata ); ventrites slightly notched at apical middle (sub-truncated in P . fulvomaculata ); tergite VIII with a feebly triangular projection at the apical middle (truncated in P . fulvomaculata ); stem of spiculum gastrale narrow (wide in P . fulvomaculata ), membrane connecting both parameres wide (narrow in P . fulvomaculata ); tegminal struts distinctly expanded towards inside near apex (not expanded in P . fulvomaculata ); venter of dorsal struts of penis distinctly constricted near apical 1/ 4 in lateral view (not constricted in P . fulvomaculata ). Type material. Holotype : male ( LPSNU ), VIETNAM . Dak Lak , IV.2019 , local collector leg . Paratype : 1 male ( LPSNU ), same data as the holotype, but III.2018 . Etymology. This new species is dedicated to Prof. Ying-Zhou Tian (mLJNJ), former president of Liupanshui Normal University, for his generous supports to this study. Distribution. Only known from type locality of Dak Lak province , Vietnam .
