Supplement to the revision of the genus Brachelytrium Obenberger, 1923 (Coleoptera: Buprestidae: Buprestinae: Anthaxiini) Bílý, Svatopluk Bellamy, Charles L. Zootaxa 2010 2721 15 27 MSCR [151,709,1674,1700] Insecta Buprestidae Brachelytrium GBIF Animalia Coleoptera 1 16 Arthropoda species mauritanicum sp. nov. Brachelytrium   Diagnosis.Small ( 4.3 mm), convex, robust, parallel-sided; dorsal surface bronze, scutellum purple; ventral surface black, lateral portion of ventrites and legs bronze with purple lustre; frons with short, white pubescence (length of setae equal to diameter of cells), remainder of dorsal surface asetose; ventral surface with very short, sparse, nearly indistinct, white pubescence, prosternum asetose.   Description of the female holotype.Length: 4.3 mm; width: 1.9 mm. Head small, as wide as anterior pronotal margin; frons flat, vertex 0.9 times as wide as eye; anterior margin of frontoclypeus straight; eyes small, reniform, not projecting beyond outline of head; antennae short, extending to mid-length of lateral pronotal margins when laid alongside; scape slightly pyriform, somewhat curved, 3.3 times as long as wide; pedicel globular, as long as wide; antennomere 3 triangular, as wide as long; antennomeres 4–10 trapezoidal, slightly wider than long; terminal antennomere nearly globular, as wide as long; sculpture of head consisting of small, dense, oval cells with large, flat central grains. Pronotum convex, somewhat wider than elytra, 1.8 times as wide as long, with poorly developed lateroposterior depressions; anterior margin nearly straight, posterior margin biarcuate; lateral margins regularly rounded, maximum width anteriad mid-length; sculpture consisting of dense, polygonal cells with small, sharp central grains; ocellation somewhat longitudinally prolonged along lateral margins. Scutellum small, lustrous, as wide as long. Elytra subparallel, 1.5 times as long as wide, shortly, obtusely rounded at apical 1/4, distinctly, widely depressed anteriad mid-length and at posterior 1/3; humeral swellings small but well-developed; basal transverse depression wide, nearly reaching scutellum; epipleuron narrow, extending to apex; sculpture rather homogenous, punctate-rugose without basal microsculpture.   FIGURES 1–8.1–6, dorsal habitus of six new species of  Brachelytrium( Brachelytrium): Fig. 1,  B. nigrum  sp. nov., holotype, 5.6 mm (maximum length); Fig. 2,  B. mauritanicum  sp. nov., holotype, 4.3 mm; Fig. 3,  B. beninense  sp. nov., holotype, 4.7 mm; Fig. 4,  B. niehuisi  sp. nov., holotype, 5.0 mm; Fig. 5,  B. purpureiventre; sp. nov., holotype, 5.2 mm; Fig. 6,  B. aeneum  sp. nov., holotype, 5.8 mm; and Figures 6, 7, dorsal habitus of two new species of  Brachelytrium( Elytrobrachium): Fig. 7,  B. caeruleum  sp. nov., holotype, 3.8 mm; Fig. 8,  B. metallicum  sp. nov., holotype, 4.6 mm.   FIGURES 9–23.9–20, dorsal aspect of male genitalia of  Brachelytrium( Brachelytrium): Fig. 9,  B. nigrum,  sp. nov.; Fig. 10,  B. africanum(Pochon, 1972); Fig. 11,  B. beninense,  sp. nov.; Fig. 12,  B. niehuisi,  sp. nov.; Fig. 13,  B. transvalenseObenberger, 1923; Fig. 14,  B. lesneiBílý & Bellamy, 2000; Fig. 15,  B. straussaeBílý & Bellamy, 2000; Fig. 16,  B. holmiBílý & Bellamy, 2000; Fig. 17,  B. fissifronsBílý & Bellamy, 2000; Fig. 18,  B. namibienseBílý & Bellamy, 2000; Fig. 19,  B. tanzanienseBílý & Bellamy, 2000; Fig. 20,  B. gibbicolleBílý & Bellamy, 2000; and Figures 21–23 of  Brachelytrium( Elytrobrachium): Fig. 21,  B. blairi(Obenberger, 1931); Fig. 22,  B. metallicum,  sp. nov.; Fig. 23,  B. ventrale(Kerremans, 1911). Figures 10, 13–21, 23 are those used in Bílý & Bellamy (2000) where no scale bars were used. The scale bars for Figs. 9, 11, 12 and 22 = 1.0 mm and are approximately to scale for the remaining figures, all drawn by the senior author from the same magnification originally, with slight scale adjustments in the creation of this plate. Figures 9–20 are to the scale of 9, 11 and 12, while Figures 21 and 23 are to the scale of 22. Ventral surface lustrous, widely, finely ocellate; anal ventrite shortly truncate to emarginate without distinct lateral serration. Legs relatively short, meso- and metatibiae straight, slightly enlarged posteriorly; tarsal claws thin, slightly hook-shaped, somewhat enlarged basally. Male unknown.  Bionomy.The holotypewas reared from  Acacia senegal(Fabaceae).   Etymology.Named after the country of the origin, Mauritania.   Distribution. Mauritania.  Differential diagnosis.  Brachelytrium( B.) mauritanicum  sp. nov.stands close to  B.( B.) tanzaniense Bílý & Bellamy, 2000and differs from it (except for the distribution) by a smaller, more slender, lustrous body, small, sharp central grains on the pronotum (large, flat grains in  B.( B.) tanzaniense) and by the finer elytral sculpture.  Brachelytrium( B.) mauritanicum  sp. nov.resembles very much the nearly sympatric  B.( B.) beninense  sp. nov.from which it differs by having a finer and denser frontal ocellation, narrower pronotum, wider pronotal ocellation which is longitudinally prolonged along the lateral margins, a smaller and lustrous, purple scutellum and by the sparser but rougher elytral sculpture;  B.( B.) beninense  sp. nov.also possesses more distinct elytral depressions.
