Derivation of name
. From apici (Latin= small) plus spina (Latin= spine) for the small spine in the exterior apical angles of the elytra.
Diagnosis
. This species is in group 6 (
Uhmann 1937
). It can be distinguished from all other members of species group 6 by the fovea on the vertex of the head, having antennomeres II and III subequal in length, by the pronotum lacking a basal impression, and by the small spine in the apical exterior angles of the elytra.
Description
. Brownishyellow; eyes black; elytra with humeral and exterior apical angles margined with black, lateral margins from base to just past middle with black aeneous vitta, puncture row 2 with black vitta on first four punctures. Head: vertex with fovea which becomes sulcus, smooth; small tooth present between antennal bases; frons not angulate. Antenna: antennomere I subglobose; IIVII cylindrical, IIIII subequal in length, VVII decreasing in length; VIIIX transverse; XI pointed at apex; IVII glabrous; VIIIXI setose. Pronotum: lateral margin angulate before middle, sinuate at base, strongly converging to apex; each anterior angle with blunt tooth; posterior angle acute; disc convex, densely, coarsely punctate; basal impression absent; pronotal length
1.4 mm
; pronotal width 2.0 mm. Scutellum: quadrate; alutaceous. Elytron: lateral margin parallel for basal 1/2 then expanding, smooth; apical margin smooth; exterior apical angle with large, flattened, curved lamina; humerus produced, angular; with 10 rows of punctures plus short scutellar row; interspaces 2 and 4 costate for entire length, 6 and 8 costate at apex; elytral length
6.1 mm
; elytral width
3.4 mm
. Venter: prosternum punctate laterally; metasternum black laterally; abdomen variable, with diffuse black and yellow. Total length:
7.9 mm
.
Variation.
Specimens vary in pronotal width from 1.72.0 mm, in elytral length from 6.0
6.1 mm
, and in total length from
7.77.9 mm
. The color and sculpture is very similar to that of the
holotype
.
