( Fig. 3 View FIGURE 3 )

Type material. Holotype: [Lesser Antilles], St. Lucia.

Type material. Holotype: [Lesser Antilles], Sainte Lucie, Des Cartiers trail, 1 male, 26.vii.2014, fn 2014- LCU-SH033, S. Hugel (MNHN-EO-ENSIF4188). Allotype: Same data as the holotype, 1 female, fn 2014-LCU- SH035 (MNHN-EO-ENSIF4189). Paratypes, 1 male, 2 femelles. Same data as the holotype, fn 2014-LCU- SH034, 0 36, 0 37 (MNHN-EO-ENSIF4190-4192).

Additional material examined. Same data as the holotype, 1 male, 1 female, fn 2014-LCU-SH040-042, in alcohol (Coll. SH), 1 male, 1 female, fn 2014-LCU-SH040-042, in alcohol ( MNHN, vial number 630).

Type locality. Lesser Antilles , St. Lucia, Des Cartiers trail.

Distribution. Lesser Antilles, St. Lucia.

Diagnosis. Within the genus, species most similar to A. vincenti n. sp., especially by its small size. It can be separated from the latter species by the yellowish margin of its cheeks, details in coloration of the head and pronotum, and details in male genitalia.

Description. In addition to characters of the genus ( Desutter-Grandcolas, 1993):

Size similar to A. vincenti n. sp., smaller than A. septentrion n. sp., A. alatus and A. darienicus n. comb.

Coloration. Fig. 3 View FIGURE 3 A–D. Compared to A. vincenti n. sp., head dorsum clearly yellowish along eyes inner margins ( Fig. 3 View FIGURE 3 A), face lighter below median ocellus ( Fig. 3 View FIGURE 3 B), cheeks yellow ( Fig. 3 View FIGURE 3 C), scape light yellow but antennae darker from their bases ( Fig. 3 View FIGURE 3 B); maxillary palpi yellowish, distal half of joint 5 dark brown ( Fig. 3 View FIGURE 3 B). Antennae light brown, getting darker along their length. Anterior and posterior margins of DD yellow ( Fig. 3 View FIGURE 3 A). LL and abdomen, including subgenital plate, black brown ( Fig. 1 View FIGURE 1 C), but subgenital plate lighter from above ( Fig. 3 View FIGURE 3 A). Cerci light brown. Legs yellowish brown with darker knees.

Male genitalia. Fig. 3 View FIGURE 3 E–G. Pseudepiphallic sclerite more similar to A. septentrion n. sp., but median lobes separated apically by a small notch and anterior margin of pseudepiphallic sclerite strongly sclerotized as in A. vicenti n. sp.; pseudepiphallic process shorter than in A. vincenti n. sp., thus more similar to A. septentrion n. sp. in lateral view.

Female. Subgenital plate very transverse, distal margin bisinuate; entirely black brown. Penultimate sternite black brown. Ovipositor shorter than TIII.

Female genitalia. Not examined.
