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). 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). 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). Scutellum cordiform with small, dense and plicated sculptures (Fig. 1A). 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). Legs metallic green; protarsomere 1 (Fig. 2A–C) 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), subtriangular and strongly incrassate with posterior angle more prominent than anterior one; apex of metatibia with long spur; metatarsus (Fig. 2E) 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). Aedeagus: Membranous, paramere of aedeagus strongly expanded apically, outer sides subparallel slightly concave near apices; medial lobe sharp at apex (Fig. 1C).
Sexual dimorphism. Male: see holotype description. Female: body usually larger and more robust (Fig. 1G), eyes separated on vertex in narrowest part by 11–12 rows of punctures, antennae shorter (Fig. 1E–G); metatibia with very inconspicuous spur at apex (Fig. 2F). Female ovipositor in Fig. 1H.
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) 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), and particularly by the spine on outer margin of basal protarsomere (Fig. 2A–2C). 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), 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.
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.
