Holotype
male description.
Body shape elongate. Length
14.9 mm
. Width
8.4 mm
.
Color. Head dark brown. Pronotum orange ochre with 1 large irregular dark brown macula on disc, not reaching basal margin, crossed by a lighter weak longitudinal line; small maculae on lateral foveae; surface with green luster. Scutellum light brown with lighter center. Elytra orange ochre. Pygidium ochre. Legs reddish brown; protibiae with darker margins, metafemura ochre, metatibiae and metatarsi dark brown with green luster. Venter, sternum reddish brown with darker margins, abdominal sternites ochre.
Clypeus trapezoidal, surface densely punctate-reticulate, flat. Anterior margin straight, clypeus anteriorly thin. Clypeus ratio width/length 2.3. Frons densely punctate, flat. Ocular canthum long, thin, with rounded apex. Interocular ratio (interocular width/width of eye): 2.9.
Pronotum subtrapezoidal. Ratio width/length 1.7. Lateral margins angulated at 1/3 of pronotum length. Apical angles acute, sharp; basal angles obtuse, blunt. Basal margin sinuate, subapical bead complete. Surface densely punctate.
Scutellum. Shape subtriangular, with rounded sides, apex acute. Ratio width/length 1.5. Surface densely punctate.
Elytra with costae defined by regular rows of punctures. Subsutural interstice with 3–5 rows of punctures, 2nd– 4th interstices with 1–2 irregular rows of punctures. Surface covered with secondary punctures.
Pygidium finely granulate with long setae at apical margin. Ratio width/length 1.4.
Space between the mesocoxae narrow, flat. Mesometasternal suture well defined, at base of mesocoxae. Abdominal sternites with 1 row of sparse setae and 5–6 rows of punctures per sternite. Terminal sternite punctate, with subapical bead narrow and sinuate, apical membrane narrow.
Protibia (Fig. 8) bidentate; apical tooth long and curved; basal tooth below internal apex of protibia, triangular in shape, acute. Metatibia stout, slightly narrower subapically. Ratio length/width 2.6. First external carina obliterated; surface densely punctate above second external carina, rugose below. Protarsal claws: internal claw bifurcate, with upper branch of same length and 2/3 the width of the lower branch; inferior margin sinuate.
Aedeagus (
Fig. 14
): parameres with sinuate dorsal and ventral margins, apex acute in a lateral view. Endophallus (
Fig. 20
) with 1 long sacculus with wide apex, covered with setae medially and with a strip of long and short, thick spines at apex. Ejaculatory duct opening placed on a ventral inflation.
Variation.
Macula on pronotum with variable extension either fusing with maculae on foveae, forming a starshaped macula or reaching the posterior margin; elytra ochre to red. Female. Similar to male, protibia (Fig. 8) with longer and wider apical tooth; basal tooth above internal apex; internal protarsal claw with curved inferior margin.
Body length
14.4–16.1 mm
, body width
7.9–9.6 mm
. Clypeus w/l: 2.2–2.3. Interocular ratio (interocular width/width of eye): 2.5–3.0. Antenna: ratio funiculus/club 0.6–0.7. Scutellum w/l: 1.2–1.5. Pygidium w/l: 1.4–1.6. Metatibia l/w: 2.5–2.8.
Diagnosis.
Size large; macula on pronotum irregular, dark; elytra ochre; parameres with sinuate dorsal and ventral margins in lateral view; endophallus with a strip of long and short, thick spines at apex.
Anomala jansoni
Ohaus, 1897
is a similar species of similar size but with two small maculae on pronotum and parameres with long, narrow, curved apex (
Fig. 29
) (Monte Rotondo,
Costa Rica
; MNHUB).
Anomala antica
Ohaus, 1897
,
A. luciae
Blanchard, 1851
, and
A. quiche
Ohaus, 1897
are similar but smaller species, with one small and pentagonal macula on pronotum (
A. antica
), pronotum with sinuate lateral margins (
A. quiche
), maculae on elytra (
A. luciae
and
A. quiche
), and differences in the parameres:
A. antica
has a long thin apex (
Fig. 30
),
A. luciae
has lobes on anterior portion of inferior margins (
Fig. 31
), and
A. quiche
has wide rounded parameres, and the ventral plate curved at apex in a lateral view (
Fig. 32
).
Etymology.
Latinized from the Spanish noun
estrella
, star, for the star-shaped macula on pronotum. Treated here as a noun in apposition,.
Distribution:
Guanacaste and Tilarán mountain ranges,
Costa Rica
, from
280–1520 m
(
Fig. 34
).
