Holotype description. Length: 5.4 mm, length of elytra: 3.3 mm, width: 3.0 mm. Body oblong, black; elytra reddish brown with narrowly black borders; dorsal surface dull with long, dense, erect setae; pilosity on head and anterior pronotum black, on pronotum base and elytra dark yellow. Head: Labroclypeus transverse, widest medially with lateral margins strongly convex and convergent anteriorly and toward base, anterior angles strongly rounded, lateral border and ocular canthus producing a distinct blunt angle, anterior and lateral margin strongly reflexed, anterior margin moderately sinuate medially. Surface almost flat medially and moderately shiny with double punctation; punctures coarse, dense, each bearing a long, erect seta mixed with fine glabrous punctures. Frontoclypeal suture distinct, weakly curved, slightly elevated; smooth area anterior to eye as wide as long. Ocular canthus moderately long, slender; finely, densely punctate; densely setose. Frons with double punctation; punctures coarse, dense, each bearing a long, erect seta; coarse punctures mixed with fine glabrous punctures; posteriorly punctation sparser. Eyes small, ratio of diameter / interocular width: 0.48. Antenna with ten antennomeres, dark yellow; club brown with five equal in length antennomeres; club 2.5 times as long as remaining antennomeres combined, reflexed. Prementum flat. Pronotum: widest at base; lateral margins in posterior half almost straight and subparallel, strongly convex and convergent in anterior third; anterior angles not produced, moderately rounded; posterior angles blunt, weakly rounded; anterior margin weakly convex medially with distinct, fine marginal line; basal margin with fine marginal line. Pronotal surface with dense, double punctation; punctures fine, glabrous, mixed with large punctures, bearing a long erect seta; pilosity moderately dense; anterior and lateral borders setose; basal margin of hypomeron not produced ventrally, not transversely sulcate anterior to base. Scutellum : moderately long, apex sharp with fine and irregularly dense punctures; posterior third almost smooth; minute setae present in punctures. Elytra: oblong; widest medially; striae indistinctly impressed with fine, dense punctures; intervals flat with fine, moderately dense punctures; punctures with long, erect, evenly dense setae; even intervals setose at base; sutural interval with robust, long seta. Epipleural edge fine, ending at strongly convex external apical angle of elytra; epipleura densely setose; elytra strongly curved in anterior third; apical border chitinous; without short microtrichomes. Venter: Ventral surface dull with fine, dense punctures. Metasternum with dense, long setae; setae partially appressed, partially erect. Metacoxa with moderately dense, fine, long appressed setae. Abdominal sternites with indistinct transverse row of coarse punctures bearing thick setae between fine, dense punctation; all sternites with fine, long setae; tegument of abdominal sternites (60x magnification) with fine polygonal mesh pattern formed by microtrichomes; penultimate sternite at midline with longitudinally impressed line. Mesosternum between mesocoxae narrow, narrower than mesofemur, with irregularly scattered, strong setae. Ratio of length of metepisternum / metacoxa: 1 / 1.51. Pygidium moderately convex, dull with fine, dense punctures bearing fine, long setae; pilosity denser along apical margin; without smooth midline. Legs: slender with shiny surface. Femora with two longitudinal rows of setae; punctures fine, dense, setose. Metafemur with anterior edge acute, lacking adjacent serrated line; posterior margin weakly convex with a few fine setae medially; ventral posterior margin weakly widened in apical half; posterior margin smooth ventrally and dorsally. Metatibia moderately slender and long, widest at apex; ratio width / length: 1 / 3.3; dorsally with moderately sharp edge, not serrate; with two groups of spines, basal group at one third, apical one at two thirds of metatibial length; basally with a few single spines in punctures; lateral face longitudinally convex with moderately dense, fine, glabrous punctures; ventral edge serrated with four strong, long, equally spaced spines; medial face finely punctate; apex sharply truncate interiorly near tarsal articulation. Tarsomeres dorsally glabrous with fine, dense punctures; ventrally with sparse, short setae; metatarsomeres dorsally without longitudinal impressions, ventrally with strongly serrated ridge adjacent to strong longitudinal carina, laterally without strong longitudinal carina; first metatarsomere slightly shorter than the following two tarsomeres combined and slightly longer than the upper tibial spur. Protibia short, bidentate. Protarsal claws asymmetrical; basal tooth of inner protarsal claw widened and truncate apically. Aedeagus: Fig. 2G–J View FIGURE 2 .

Intraspecific variation. Length: 5.0– 5.4 mm, length of elytra: 3.0– 3.3 mm, width: 2.5– 3.0 mm. Coloration variable, paratypes uniformly brown, or elytra dark yellow with larger sutural interval, 1–2 adjacent intervals, lateral edge largely dark. Density of punctation on dorsal surface variable. ♀: antennal club with three antennomeres and distinctly shorter than the remaining antennomeres combined; eyes equal in size to that of male.

Diagnosis. Anomalophylla subfastuosa is similar to A. liciata in external shape and genital morphology of male. It differs from A. liciata by the evenly straight and narrow right paramere, the dorsoventrally flattened left paramere, and the slender and sharply pointed lateral apophysis of the phallobase.

Etymology. From Latin prefix sub­ (rather) and the adjective fastuosus (splendid, beautiful).
