Holotype male description. Body shape elongate. Length 17.5 mm. Width 9.7 mm.
Color. Head, pronotum, and scutellum metallic green. Elytra metallic green with branched ochre lines along apical portion of costae and coppery luster. Pygidium bronze. Legs metallic green with coppery luster. Venter dark metallic green, abdominal sternites copper.
Clypeus trapezoidal, surface densely punctate, convex. Clypeus anterior margin slightly sinuate, anteriorly thick. Clypeus ratio width/length 2.5. Frons moderately punctate, flat. Ocular canthum long, thin, with rounded apex. Interocular ratio (interocular width/width of eye): 3.0. Antenna: ratio funiculus/club 0.7.
Pronotum subtrapezoidal, ratio width/length 1.9. Lateral margins sinuate. Anterior angles acute, sharp; posterior angles obtuse, blunt. Basal margin sinuate, subapical bead obliterated in the middle. Surface with fine punctures.
Figures 7–12. Shape of protibia in 7: Anomala aglaos (male: holotype; female: paratype, Isla Bonita, Costa Rica). 8: A. estrella (male: holotype; female: paratype, Los Almendros, Costa Rica). 9: A. inbio (male: holotype; female: paratype, Reserva Biológica Hitoy Cerere, Costa Rica). 10: A. pincelada (male: paratype, Parque Nacional Santa Rosa, Costa Rica; female: paratype, Tierras Morenas, Costa Rica). 11: Callistethus ruteloides (male: holotype; female: paratype, El Copal, Cartago). 12: Shape of protibia of Callistethus yalizo (male: paratype, Esperanza del Guarco, Cartago; female: paratype, Quebrada Segunda, Cartago). Scale = 1 mm.
Scutellum. Shape subtriangular, with rounded sides and blunt apex. Ratio width/length 1.4.
Elytra with costae defined by irregular rows of sparse punctures. Interstices with sparse, shallow punctures; surface slightly irregular.
Pygidium sparsely punctate with long setae at apical margin. Ratio width/length 1.5.
Space between the mesocoxae narrow, flat. Mesometasternal suture well defined, at base of mesocoxae. Abdominal sternites with 1–2 rows of setae (2–3 rows on 2nd sternite) and 6–8 rows of punctures per sternite. Last sternite punctate, with subapical bead thin and sinuate, apical membrane narrow.
Protibia (Fig. 7) bidentate; apical tooth long and curved; basal tooth at same level as internal apex of protibia, triangular in shape, acute. Metatibia slender, fusiform. Ratio length/width 3.2. First external carina obliterated. Surface punctate above second external carina and rugose below. Protarsal claws: internal claw bifurcate, with upper branch of same length and 2/3 the width of the lower one, inferior margin sinuate.
Aedeagus (Fig. 13): parameres large and stout in a lateral view, but narrow dorsally. Ventral plate with curved apex in a lateral view. Endophallus (Fig. 19) with 2 long sacculi; 1 ending with a pair of thick, long, sclerotized projections with a long diverticle in between, and with a patch of sclerotized spines medially; the other sacculi with swollen base, where ejaculatory sclerite and duct opening are located, and a ridged plate of thick spines at apex. Median lobes asymmetric, 1 with a triangular fold near apex.
Variation. Ochre lines on elytra of variable length; elytra with green or copper luster. Female. Similar to male, protibia (Fig. 7) with longer and wider apical tooth; basal tooth above internal apex; internal protarsal claw narrower with curved inferior margin; last sternite with curved apex.
Body length 17.5–18.8 mm, body width 9.7–10.2 mm. Clypeus w/l: 2.3–2.7. Interocular ratio (interocular width/width of eye): 3.0–3.4. Antenna: ratio funiculus/club 0.7–0.9. Pronotum w/l: 1.8–1.9. Scutellum w/l: 1.4– 1.6. Pygidium w/l: 1.5–1.6. Metatibia l/w: 2.9–3.5.
Diagnosis. Size large, shape elongate, metallic green color with branched ochre lines on apical portion of elytra, elytral surface irregular, parameres large and stout, endophallus with a pair of long, sclerotized projections.
This species is similar to A. obovata Ohaus, 1933, with the slightly bigger size, oblong shape, and dark green color; but A. obovata lacks the ochre lines on elytra, its elytral surface is strongly irregular with large and deep coalescing punctures, and it has slender parameres (Fig. 27), endophallus with a sacculus with a large patch of dense setae on basal portion, instead of sclerotized projections (Fig. 28).
Etymology. From the Greek adjective aglaós, splendid, beautiful, treated as a noun in apposition, for the nice and elegant aspect of this species.
Distribution. Guanacaste and Central mountain ranges, Costa Rica, from 800–1100 m (Fig. 34).
