Holotype. Male ( Fig. 5 View Figs ). Body oval. Length 10.88 mm, width 5.52 mm. Head reddish brown. Pronotum dark brown on disc, with sides and basal median part ochre. Scutellum dark brown with reddish sides. Elytra ochre with dark brown margins, expanding on median and apical parts of suture; punctures of striae pigmented. Pygidium, legs, and venter ochre. Head: Clypeus trapezoidal, surface densely punctate-reticulate, convex. Anterior margin straight, clypeus thin in frontal view, width/length ratio 2.24. Frons punctate, less densely than clypeus, with a triangular concavity. Ocular canthus long, thin, with rounded apex. Ratio of interocular width/width of eye 2.99. Ratio antennal funiculus/ club 0.73. Pronotum: Subtrapezoidal. Ratio width/ length 1.7. Lateral margins angulated at 1/3 of pronotal length from the anterior margins. Anterior angles quadrate, posterior angles obtuse. Basal margin sinuate, subapical bead complete. Surface with deep dense punctures. Scutellum: Subtriangular, with rounded sides and acute apex. Ratio width/length 1.38. Surface densely punctate. Elytra: With costae defined by regular rows of punctures. Subsutural interstice with 2–4 rows of sparse punctures, 2 nd –4 th interstices with 1 irregular, secondary stria. Surface covered with secondary punctures. Pygidium: With coalescing punctures and long setae on posterior margin. Ratio width/length 1.66. Venter: Space between mesocoxae narrow, slightly convex. Mesometasternal suture well-defined at base of mesocoxae. Abdominal sternites with 1 row of setae and 3–5 rows of punctures per sternite. Sixth abdominal sternite slightly raised, as a bump. Last sternite punctate, with subapical bead thick and sinuate, apical membrane wide. Legs: Protibia ( Fig. 13 View Figs ) tridentate, apical tooth long and curved, middle tooth below internal apex of protibia triangular, acute, basal tooth scarcely developed. Metatibia fusiform. Ratio length/ width 3.23. First external carina well-developed. Surface punctate. Internal protarsal claw bifurcate, with upper branch slightly shorter, as wide as the width of the lower one, inferior margin curved. Male genitalia: Parameres short with wide, blunt apex in lateral view ( Fig. 21 View Figs ), ventral margin sinuate. Endophallus ( Fig. 29 View Figs ) composed of a long sacculus, with a ridge of sclerotized spines at about half the length and a stripe of sclerotized setae at base. Ejaculatory opening lateral, at apex of an inflation.

Female. Similar to male except protibia ( Fig. 13 View Figs ) with longer and wider teeth, last sternite with curved apex.

Variation. Nine paratypes. Head and pronotal disc vary from reddish to dark brown; extension of dark maculae on pronotum variable to almost dark with thin, ochre sides; dark lateral bands and median expansion on elytra variable in width; venter varies from ochre to light brown. Body length 10.26–11.76 mm, body width 5.52–6.38 mm. Clypeal width/length ratio 2.00–2.24. Ratio of interocular width/width of eye 2.91–3.05. Ratio of antennal funiculus/club 0.73–0.87. Pronotal width/ length ratio 1.62–1.72. Scutellar width/length ratio 1.33–1.49. Pygidial width/length ratio 1.59–1.73. Metatibial length/width ratio 2.79–3.23.

Etymology. From the Greek prefix méso s, middle, and adjective stiktós, maculated, for the central macula on the elytra.

Distribution. Anomala mesosticta occurs in the Caribbean lowlands of Costa Rica, from 0 to 200 m elevation ( Fig. 35 View Figs ).

Diagnosis. This species is recognized by its ochre elytra with dark brown margins expanding medially, tridentate protibia, and parameres short with a wide blunt apex. This species has an elytral pattern similar to that of Anomala denticollis Bates, 1888 ( Guatemala) , and A. hoepfneri . The former species has sinuate lateral margins on the pronotum and black maculae on the calli, which are not present in A. mesosticta . The latter species is larger, has dark maculae on the basal calli and light-colored lateral elytral margins, and wide interstices on the elytra with several irregular rows of punctures.
