description: <i>Anomala ordinata</i> spec. nov. urn:lsid:zoobank.org:act: 1177FA2D-BF2B-417C-8B01-BD230DBC23DE (Figs 5, 14) <b>Type series</b>: <b>Holotype</b>: , C. VIETNAM: Quang Nam dist near Danang 16.IV.-15.V.2010. (NSMT). Paratypes: 2 , 2 , C-VIETNAM Tua Thien Hue Prov. Bach Ma Natl. Park, surr. Hotel Morin (1350-1400 m), 16,2°N 107,85°E 23.-28.V.2014 (at light) / legit L. Bartolozzi, G. Chelazzi, A. Bandinelli, S. Bambi, F. Fabiano (n° Magazz. 2978) (CZPC, MZUF). <b>Description</b>: Body shape broadly ovoid, rather weakly convex; body length: 21.1-24.1 mm, width: 11.8-12.7 mm. <b>Color</b>. Entire body dark brown to reddish brown with strong iridescent shine. <b>Head</b> with erect yellow setae (0.5-0.75 mm in length) along eyes; interocular distance equals 0.65 times the maximum transverse head width. Clypeus trapezoidal with broadly rounded front angles, strongly reticulately punctate; anterior margin enlarged and distinctly reflexed; fronto-clypeal suture weakly sinuate. Frons very densely punctate, punctures sparser and smaller medially and posteriad. Vertex with dense punctation. <b>Pronotum</b> 1.8 times as wide as long; sides convergent in anterior 2/5, almost straight and subparallel in posterior 3/5; widest at base; lateral marginal line disappearing before reaching the hind angles; base without trace of marginal line; front angles produced and acute, hind angles completely rounded off; disc with dense, transverse punctures, each puncture bearing a distinct short seta which is approximately as long as the puncture; with erect brownish setae (0.75-0.88 mm in length) along lateral margins. <b>Scutellum</b> 1.5 times as wide as long, apex rather rounded; irregularly scattered with transverse punctures, bearing a short seta. <b>Elytra</b>. Regularly striate-sulcate; intervals moderately convex; each stria marked by a regular line of round, well separated, hairless punctures; entire surface covered with strongly transverse, short-seta-bearing punctures which are partly adjacent to each other in proximity of the striae; irregular punctation denser near shoulder and apex; punctures becoming sparser and small towards suture; subsutural interstice covered with a mixture of both types of punctures in the central part, somewhat sulcate in the posterior half; elytra laterally somewhat flanged; epipleura strong, disappearing rather abruptly shortly before apical curvature; marginal membrane starting near middle of metacoxa. <b>Pygidium</b> triangular, somewhat tumid and pointed at apex; with dense transverse striolation which is arranged concentrically around the tumidity; with scarce reddish brown setae (0.13-0.88 mm in length) in basal and apical portions. <b>Mesoventrite</b> very narrow and somewhat concave between the approximated mesocoxae. <b>Metaventrite</b> densely covered with partly confluent transverse punctures, with yellowish brown setae (0.25- 0.5 mm in length) in lateral portions; sparsely punctate and almost glabrous in the middle. <b>Abdominal ventrites</b> densely covered with very transverse punctures which confluate laterally, each puncture bearing a short seta; 2nd to 4th abdominal ventrite with a transverse row of semierect yellow setae (0.3-0.38 mm in length); 1st to 3rd abdominal ventrite strongly carinate laterally. <b>Legs</b> rather slender, moderately long; protibia bidentate; terminal tooth rather short, somewhat pointed at apex; protarsal segment 5 ventrally with a sharp tooth approximately in the middle; inner protarsal claw and outer mesotarsal claw apically incised; the upper branch of the inner protarsal claw small and slender, the lower branch broad, somewhat enlarged ventrally but without tooth; the upper branch of outer mesotarsal claw slightly more slender than the lower one. <b>Females</b>: Body shape somewhat stouter, pronotum more convex and the sides more rounded; pygidium convex but not tumid, with impressions near each latero-basal angle; terminal tooth of protibia spatulate; modified protarsal claw less enlarged. <b>Diagnosis</b>: <i>Anomala ordinata</i> is very distinctive in bearing very short but distinct setae on pronotum and elytra. The length of these setae approximately equals the length of the associated puncture. All other Asian species with distinct dorsal setosity, including those subsumed in the <i>hirsutula</i> -group (LIN 1996), have longer setae. Apart from the setosity, <i>A. ordinata</i> cannot be confused with similar species with sulcate elytra because of the combination of a large body size, a rather broad body shape and dark brown coloration. The structure of the boot-shaped aedeagus is unique within <i>Anomala</i> (fig. 14). There appears to be no closely related species. <b>Etymology</b>: The specific epithet is formed by the Latin adjective “ordinatus, -a, -um” and translates as “put in order”. It is an allusion to the evenly striate elytra in the new species.
