Description of
holotype
(male)
. Length 3.82, width
2.81 mm
. Form elongate oval, widest at middle of elytra, flattened dorsoventrally (
Fig. 2
C). Dorsal and ventral general color reddish brown (
Figs. 2
A, B). Outline of pronotum and elytron discontinuous. Antenna, mouthparts, hypomera, epipleura and legs reddish brown. Clypeus and frons joined at abrupt angle. Pronotum translucent; finely, densely punctured, punctures uniform in size, with a slight depression at lateral sides; pubescence of semidecumbent yellowish hairs; with black spot at base (
Fig. 2
D). Elytra reddish brown with a black spot chalice-shaped in the middle, not reaching humeral callus (
Fig. 2
A). Elytral punctures coarse, dense, slightly larger than on pronotum and similarly dense, uniform in size. Metaventrite finely, sparsely punctured medially and anteriorly; coarsely, densely punctured laterally and posteriorly with punctures large, often confluent; each puncture with long, yellow, decumbent seta. Abdominal ventrites coarsely punctured, punctures separated by about twice a diameter, punctures becoming coarser laterally and on last ventrite. First abdominal ventrite with postcoxal line extending beyond middle of ventrite (
Fig. 2
E). Genitalia with basal lobe equal in length to paramere, lateral margin slightly thickened, parameres slightly curved in lateral view (
Figs. 2
G, H); sipho sinuous, apex nearly membranous, unmodified (
Fig. 2
F).
Female
. Length 4.21, width
3.02 mm
. Similar to male in all aspects externally. Genitalia with genital plates elongate, styli with setae; spermatheca elongate, unmodified (
Fig.
2
I).
Etymology
. The name of this species refers to the shape of black spot of the elytra.
Discussion
.
Oryssomus calix
sp. nov.
is similar to
O. guillermo
sp. nov.
and
O. unimaculatus
, but is clearly distinguished by the chalice-shaped spot on the elytra, and the genitalia.
