Diagnosis.
Species small, close to
A. chopardi
and
A. humboldti
n. sp.
from which it differs by the shape of the pseudepiphallus in male genitalia.
Description.
Size small for the genus. Colouration little contrasted, mostly light brown. Head dorsum with 6 brown longitudinal bands. Fastigium setose, brown with dark spots. Scapes light brown with dark brown patterns anteriorly, antennae dark brown with yellow rings. Cheeks black dorsally, dark brown ventrally. Face homogeneously brown, the dorsal limit with fastigium black. Mouthparts and palpi dark brown. Pronotum: Dorsal disk almost homogeneously brown. Lateral lobes black. Legs: FI, FII yellow brown with faint dark brown spots; TI, TII yellow brown with 2 dark brown rings; tarsomeres yellow brown, their distal part black. Legs III almost homogeneously brown; tarsomeres
III-1
dark brown with a yellow brown ring. TIII serrulation: 6 inner and 10 outer spines above spurs; 7 inner and 9 outer spines between spurs. Tarsomeres
III-1
: 1 spine on dorsal inner edges; 3 spines on dorsal outer edges; 1 outer lateral spine. Abdomen and cerci almost homogeneously brown.
Male:
FW not reaching abdomen mid length. Dorsal field clearly shorter than lateral field. FW colouration: Cells and veins homogeneously brown, except MP, dark brown, and a yellowish sclerotized area around 1A and posterior to the plectrum; lateral field homogeneously brown. FW venation (
Fig. 1
B): CuP absent; diagonal strong; harp triangular, flat, with 2 complete transverse veins, the anterior one faint; c1 cell wide, partly crossed by a transverse vein; D alignment and mirror (d1) little differentiated. Apical field restricted to one cell in E alignment (e1). Lateral field: Latero-dorsal angle made by MP; distal part of MP weak, fusion with MA not visible; R bifurcated once at mid length; ventral part of lateral field with 7 longitudinal veins.
Male genitalia (
Figs 1
F–H): Very similar to that of
A. chopardi
. Dorsal face of pseudepiphallic sclerite with lateral crests forming a dorsal furrow; median process wider than in
A. chopardi
and
A. humboldti
n sp.
, spoon-shaped, with 4 wide apical teeth. Pseudepiphallic apex with ventral crest very close together.
Female:
