Description of the holotype. Well preserved ♁ specimen. Length 6.89 mm, width 2.25 mm, length/width ratio: 3.06.

Body: suboval, elongate; head, legs, scutellum and ventral side metallic green; pronotum blackish medially, lateral sides golden-green with white efflorescence on lateral impressions; elytra violet to violet-reddish, basal fifth near suture with metallic green stripe, outer margin of elytra greenish-blue. Dorsal side with short, dense, pale pubescence ( Fig. 1A View FIGURE 1 ). Head: vertex roughly punctate, in narrowest part between the eyes reduced to two rows of punctures; antennae reaching to about half of pronotal length; antennomeres 1 and 2 swollen, 1 coniform, 2 globoid, 3–5 filiform, 6–11 serrate ( Fig. 1A View FIGURE 1 ). Pronotum strongly transverse, 2.01× as wide as long, widest in the middle, sides strongly curved; anterior pronotal lobe weakly bisinuate; disk with obvious, deep impressions; lateral impressions covered with white efflorescence ( Fig. 1A View FIGURE 1 ). Scutellum cordiform with small, dense and plicated sculptures ( Fig. 1A View FIGURE 1 ). Elytra about 2.39× as long as wide; across humeral part slightly wider than widest part of pronotum; densely covered with white to yellow pubescent hairs; elytral apices subtruncate, with small lateral spines, space between the spine only slightly sinuate ( Fig. 1A View FIGURE 1 ). Legs metallic green; protarsomere 1 ( Fig. 2A–C View FIGURE 2 ) with a sharp spine on outer angle extending downward and inward to anterior margin of protarsomere 2; protarsomere 1 distinctly longer than protarsomeres 2–4 together; mesotarsomere 1 ( Fig. 2D View FIGURE 2 ), subtriangular and strongly incrassate with posterior angle more prominent than anterior one; apex of metatibia with long spur; metatarsus ( Fig. 2E View FIGURE 2 ) without sexual modifications; metatarsomere 1 shorter than metatarsomeres 2–5 together. Underside metallic green to blue with dense pale, semierect pubescence; prosternal process subparallel and flat; inner posterior angle of metacoxal plates subangulate; intercoxal abdominal process impressed; disk of last ventrite flat, apex of last ventrite subtruncate ( Fig. 1B View FIGURE 1 ). Aedeagus: Membranous, paramere of aedeagus strongly expanded apically, outer sides subparallel slightly concave near apices; medial lobe sharp at apex ( Fig. 1C View FIGURE 1 ).

Sexual dimorphism. Male: see holotype description. Female: body usually larger and more robust ( Fig. 1G View FIGURE 1 ), eyes separated on vertex in narrowest part by 11–12 rows of punctures, antennae shorter ( Fig. 1E–G View FIGURE 1 ); metatibia with very inconspicuous spur at apex ( Fig. 2F View FIGURE 2 ). Female ovipositor in Fig. 1H View FIGURE 1 .

Variability. Body ♁♁ (n=42) length: 6.08–7.85 mm, width: 2.04–2.60 mm, length/width ratio: 2.98–3.02; ♀♀ (n=4) length: 6.37–10.29 mm, width: 2.23–3.72 mm, length/width ratio: 2.77–2.86.

Diagnosis. All diagnostic characters only refer to the males. Coomaniella sunfengyii Liao, Su, Qi & Song , sp. nov. ( Fig. 1A–B View FIGURE 1 ) belongs to the C. macropus species-group as defined by Jendek & Kalashian (1999) by the arcuate sides of pronotum; bidentate elytral apices, subangulate (not spinate) inner posterior angle of metacoxal plates; strikingly incrassate basal mesotarsomere ( Fig. 2D View FIGURE 2 ), and particularly by the spine on outer margin of basal protarsomere ( Fig. 2A–2C View FIGURE 2 ). The following set of characters will help to recognize this new species more precisely from other related species: 1) dorsal surface (except eyes) tricoloured rather than almost monochromatic or bicoloured as C. daoensis Jendek & Kalashian, 1999 , C. humeralis Jendek, 2021 , C. isolata Jendek & Kalashian, 1999 , C. janka Jendek, 2005 , C. lao Jendek & Kalashian, 1999 and C. sausa Jendek & Kalashian, 1999 ; 2) male antennae shorter, only reaching to about half of pronotal length rather than antennae longer, reaching to posterior pronotal angles as C. calcarata Jendek & Pham, 2013 and C. copipes Jendek & Pham, 2013 ; 3) spine of protarsomere 1 reaching anterior margin of protarsomere 2 rather than reaching anterior margin of protarsomere 3 as C. simulatrix Jendek & Pham, 2013 ; 4)parameres of aedeagus expanded before apex, outer sides subparallel, slightly concave (red arrows in Fig. 1C View FIGURE 1 ), rather than outer sides of paramere arcuate apically or subparallel but not concave near apices as C. macropus Théry, 1929 , C. nativa Jendek & Kalashian, 1999 , C. orlovi Jendek & Kalashian, 1999 and C. pacholatkoi Jendek & Kalashian, 1999 . Differences of the new species and some similar species are also showed in Table 1 View TABLE 1 .

Distribution. China (Fujian).

Etymology. This species is named after Mr. Feng-Yi Sun (Yongan, Fujian, China), who firstly found the new species and provided the type specimens for our study.

Adult host plant. Melia azedarach L.
