DIAGNOSIS: Uniformly small beetles (
4 mm
); the cranium, pronotum, legs, and abdomen are cyanescent; the pygidia are trigonal; aedeagus distinctly sagittate; elytral discal setal tuft as in figure 165. Tegmen as in figures135 and 136.
DESCRIPTION:
Size
: Length
4.1–4.5 mm
; width 1.7–2.0 mm.
Integument
: Cranium, pronotum, legs, and abdomen cyanescent; elytra piceous.
Vestiture
: Integument vested predominantly with dark setae, few pale setae; metepisternal, sutural tuft moderately developed, elytral discal tuft bipartite, anterior and posterior patches widely separated, setae of anterior patch directed anteriorly, setae of posterior patch directed posteriorly.
Head
: Width across eyes same as width across pronotum (22:22) finely punctate; interocular depressions and frontal umbo shallow; eyes subspherical, moderately convex, antenna as in figure 62.
Thorax
: Pronotum subequal in width and length (22:24), narrower than width of elytron across humeri (22:27); finely punctate, side margins subparallel, feebly incised by anterior transverse depression; elytral depth at humerus 14, greatest depth in posterior half 20; humeral umbo prominent.
Abdomen
: Pygidia (figs. 110, 112) trigonal; sixth visible abdominal sternum deeply incised in female (fig. 113), moderately incised in male (fig. 111).
Male genitalia
: As in figures 135 and 136.
VARIATION: In some specimens the elytra tend to be more brunneus than piceous (which may reflect a teneral condition of the specimens). The extent of development of the posterolateral outer angles of the parameres are variously expressed.
NATURAL HISTORY: No information available.
DISTRIBUTION (map 21): Known only from
Guatemala
.
ETYMOLOGY: The trivial name is taken from the Latin feminine
sagitta
(arrow). I refer to the arrowshaped apex of the aedeagus.
