156ED405DA6451B5BE1611D788DE8B43.taxon	discussion	Discussion. The female (Figs 11, 12) differs from the male (Figs 9, 10) by its stouter body and more convex elytra, which are parallel-sided in the anterior two-thirds, then tapering, apices separately rounded. Elytra shiny black with red tinge in posterior half, green elytral maculae same as in male. Ventral side black to dark blue-green with a shiny green stripe in the anterior margin of the prosternum and mesosternum, and with a narrow stripe along the lateral margins of the sternites. Anal sternite with a “ Y ” notch (in male notch widely rectangular).	en	Plachetka, Mikuláš (2025): A new species of Anthaxia (Merocratus) Bílý, 1989 (Coleoptera, Buprestidae, Anthaxiini) from Vietnam.

2004D5B8C0A356E9A8B9395C80BC2EA4.taxon	discussion	Discussion. This species is similar to Anthaxia (Merocratus) rydzii sp. nov., but it can be distinguished by a more distinct elytral pattern and different aedeagus. Its aedeagus is slender and has a different shape (Fig. 16).	en	Plachetka, Mikuláš (2025): A new species of Anthaxia (Merocratus) Bílý, 1989 (Coleoptera, Buprestidae, Anthaxiini) from Vietnam.

620DE6C95B1F5A298C3E85439753B719.taxon	diagnosis	Diagnosis. Large, slender, green-black species. Dorsal body surface covered by sparse, white setae. Head retracted into prothorax, black-green, frons with wide but shallow, asymmetrically rounded depression. Eyes not projecting beyond outline of head. Pronotum green, with two large, indistinct, often fused, black or dark violet maculae. Antennae slightly overlapping mid-length of lateral pronotal margins when laid alongside. Pronotum widely depressed near posterior angles. Structure of pronotum consists of polygonal cells with central grains. In prescutellar part of pronotum cells smaller, with or without central grains, forming several feeble wrinkles. Scutellum cordiform, black or black-green. Elytra subparallel, weakly wedge-shaped, tapering from humeral callosities. Elytra 2.1 times as long as wide, green with black tinge and with indistinct black macula along suture. Elytra depressed from humeral callosities along lateral margin to apex. Transverse, basal depression deep, extending from anterior margin of humeral callosities to scutellum. Legs long, blue-green to violet, covered by sparse, white setae. Protibiae green, microdenticulated on inner margins with row of short brown setae. Mesotibiae slightly bent inward with short microdenticulation on apex of inner margins. Metatibiae bent inward with several distinct teeth near inner margin of apex, both outer and inner margins with row of brown setae. Tarsal claws and adhesive pads brown.	en	Plachetka, Mikuláš (2025): A new species of Anthaxia (Merocratus) Bílý, 1989 (Coleoptera, Buprestidae, Anthaxiini) from Vietnam.

620DE6C95B1F5A298C3E85439753B719.taxon	description	Description of holotype. Holotype male (Figs 1 – 4, 14). Head retracted into prothorax, frons with wide but shallow, irregularly rounded depression. Frons green, partly with black tinge, vertex black. Sculpture of frons consists of irregularly rounded punctures with central grains, with white setae growing from central grains. Eyes large, reniform, not projecting beyond outline of head. Inner margin S-shaped. Antennae serrate, metallic green, rather long, overlapping mid-length of pronotum when laid alongside. Scape long, about 3.5 times as long as wide, claviform; pedicel barrel-shaped, approximately 2 times as long as wide; third antennomere rectangular, about 3 times as long as wide; antennomeres 4 - 10 obtusely trapezoidal; terminal antennomere oval, tip pointed. Pronotum weakly convex, approximately 1.6 times as long as wide, with wide lateroposterior depressions, lateral margins irregularly rounded. Pronotum widest in the middle, anterior margin bisinuate, lobate in the middle, anterolateral angles acute. Posterior margin shallowly bisinuate. Depression in lateroposterior angles wide, not deep. Pronotum green with black tinge, in anterior part black tinge almost covers basic green colour. Black tinge forms two anteriorly fused asymmetrically triangular maculae. Sculpture of pronotum consists of irregular, polygonal cells, mostly with central grains with short white setae. In prescutellar part of pronotum horizontal border of cells forms short, feeble wrinkles (one wrinkle is formed by border of 3 – 6 cells), with shorter vertical borders. Scutellum cordiform, as long as wide, black, with very slight green tinge. Elytra 2 times as long as wide, green with indistinct black macula around suture, partly with black tinge. Elytra subparallel, tapering from humeral callosities, depressed from humeral callosities to apex along margin, in second third depression widest, reaching half of elytral length. Elytral margins with fine microdenticulation, apices separately rounded. Sculpture of elytra consists of very fine wrinkles. Space between them often with small, deep, rounded punctures. Elytra with sparse, short, white pubescence. Deep basal, transverse depression above humeral callosities reaching scutellum. Green colour of elytral surface in this depression and in circumscutellar triangle lighter than in rest of elytra. Ventral side black, partly with green or golden tinge, with lustrous reflection. Structure of pronotum consists of asymmetrically rounded cells with central grains with long white setae. Prosternum black, prosternal process with green tinge. Sternites black with green or golden tinge. All sternites slightly depressed near lateral margins, slightly truncate with irregularly S-shaped lateral margins. Anal sternite with irregularly circular depression in the middle and depression along apex, without notch. The shape of anal sternite significantly changes based on angle of view (Figs 3, 4). Legs rather short, green to blue-green, covered with sparse, rather long, white setae. Protibiae slightly bent inward with pale brown setae along two-thirds of apical inner margins. Mesotibiae slightly bent inward, with pale brown setae only near apex of inner margin. Metatibiae bent inward with six distinct teeth near apex of inner margin, with pale brown setae on apical margins. Procoxae and mesocoxae green. Metacoxae black with green margins. Structure same as prosternum, outer lateroposterior angles acutely protruded, inner lateroposterior angle acute, forming small spine. Femora blue-green, metafemora and metatrochanters with white setae on lateral margins. Tarsi blue-green, adhesive pads and tarsal claws brown. Tarsal claw simple, only slightly enlarged near base. Aedeagus (Fig. 13 – paratype, Fig. 14 – holotype) well sclerotized, stout. Parameres laterally, angulately widened, then narrowing, near apex with indistinct serration, with only few pale brown setae. Median lobe wide, with reticulate microsculpture, lateral margins as dark as parameres, central area and apex brighter. Apex tapering to rather wide, rounded tip.	en	Plachetka, Mikuláš (2025): A new species of Anthaxia (Merocratus) Bílý, 1989 (Coleoptera, Buprestidae, Anthaxiini) from Vietnam.
