Anastrepha antilliensis Norrbom

Recognition
Anastrepha antilliensis belongs to the daciformis species group, which differs from other species of Anastrepha in having the basal third or more of the scutellum brown, the male phallus extremely short (less than 0.30 mm long) and with the glans absent (as in the dentata group), and the female eversible membrane dorsobasally with a single, medially interrupted row of very stout scales.  Anastrepha antilliensis differs from all other species of the daciformis group as follows: scutum with medial pale stripe rounded posteriorly, and sublateral pale stripe not extended to intra-alar seta. Other useful diagnostic characters include: the posterior orbital seta, usually absent in other species of the group, usually present; C- and S-bands separated; S-band complete, basally with broad extension across vein Cu2+A1 to posterior wing margin; and scutum mostly yellow, with 2 dark brown lateral spots, one anterior to and one posterolateral to postsutural supra-alar seta, and with large, irregular dark brown area on posterior margin.

Description
Body predominantly yellow.

Head: Entirely yellow except ocellar tubercle brown. 2 orbital setae (1 from Dominican Republic has 2 on right side, 1 on left).

Thorax: Scutum with 2 dark brown lateral spots, one anterior to and one posterolateral to postsutural supra-alar seta, and with large, irregular dark brown area on posterior margin, extending to or almost to acrostichal and dorsocentral setae and including intra-alar setae. Medial pale stripe poorly differentiated anteriorly, rounded or acute posteriorly. Presutural dorsocentral pale stripe absent. Presutural lateral pale stripe poorly differentiated, appears to extend across scutum, but absent from notopleuron. Sublateral pale stripe ending at margin of dark brown area, not extended to intra-alar seta. Scutellum largely dark brown, often with small orange area around basal seta, and with medial and apical white area, sometimes divided, in Dominican Republic specimens diffuse and sometimes reduced to medial area. Anepimeron with medial dark brown spot, but pleuron otherwise without dark markings. Subscutellum and mediotergite entirely dark brown. Scutum nonmicrotrichose except lateral margin of postsutural part lateral to postsutural supra-alar seta; notopleuron mostly microtrichose; scutellum nonmicrotrichose.

Wing: Bands yellow, orange and brown. C- and S-bands separated. S-band complete, basally with broad extension across vein Cu2+A1 to posterior wing margin; subapically narrow, hyaline area in cell r2+3 extended to vein R2+3; apically broad, extended to apex of vein M. V-band extended anteriorly to vein R4+5, not connected to S-band; distal arm absent. Vein M relatively weakly curved apically, sometimes meeting costa at slight angle; M ratio 1.75-2.06.

Wing.

Abdomen: Mostly yellow. Tergite 4 with nearly complete transverse brown stripe or with only paired lateral brown spot; tergite 5 with paired lateral brown spot.

Female terminalia: Oviscape length 2.25-2.75 mm, 1.10-1.25 times as long as mesonotum. Eversible membrane, on expanded basal part, with most dorsal scales weakly sclerotized, but with one, medially interrupted row of large, strongly sclerotized, hooklike scales. Aculeus slender, less than 0.04 mm wide, except at base, length 2.39 mm; tip needlelike, nearly circular in cross-section, with several minute apical serrations, length 0.16 mm, width 0.02 mm.

Male terminalia: Lateral surstylus very short, barely extended beyond prensisetae. Phallus extremely short, less than 0.30 mm long; glans absent.
