Anastrepha murrayi Norrbom

Recognition
Anastrepha murrayi belongs to the daciformis species group, which differs from other species of Anastrepha in having the basal third 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. The extent of the dark brown area on the mesonotum, in combination with the mostly orange thoracic pleuron distinguishes A. murrayi from the other species of the daciformis group. Only it, A. antilliensis, and some A. stonei have the S-band complete. The female terminalia are relatively long compared to the other Antillean species of the group (see Table); in the other 3 species, the oviscape/ mesonotum length ratio is less than 1.35.

Description
Body predominantly orange.

Head: Yellow except ocellar tubercle brown. Posterior orbital seta absent.

Thorax: Mesonotum dark brown except pale stripes, postpronotal lobe, and anterior margin and medial half of anterior half of scutum. Medial pale stripe bilobed posteriorly, lobes moderately stout, with distinct anterolateral corner, not extended to dorsocentral seta. Presutural dorsocentral pale stripe connected anteriorly to pale area on postpronotal lobe and connected to pale sublateral stripe. Presutural lateral pale stripe incomplete, narrowly interupted at margin of scutum and postpronotal lobe, extended to level of presutural supra-alar seta, but absent from notopleuron. Scutellum dark brown except small white apical area. Pleuron mostly orange, without brown markings; dorsal margin of anepisternum and dorsal half of laterotergite white (other white markings, if present, not well differentiated in holotype). Subscutellum dark brown, mediotergite entirely orange. Scutum, notopleuron and scutellum nonmicrotrichose.

Wing: Bands yellow orange and brown. C- and S-bands connected along vein R4+5, but separated along costa (cells r1, and r2+3 with marginal triangular hyaline mark). S-band complete, basally with broad extension across vein Cu2+A1 to posterior wing margin; subapically relatively narrow, hyaline area in cell r2+3 extended almost to vein R2+3; apically moderately 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 moderately curved apically; M ratio 1.74.

Wing.

Abdomen: Tergites orange banded with posterior margins broadly white.

Female terminalia: Oviscape length 3.91 mm, 1.52 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, no more than 0.04 mm wide, except at base, length 3.24 mm; tip needlelike, nearly circular in cross-section, with apex broken, length at least 0.11 mm, width 0.03 mm. Spermathecae not studied.

Male terminalia: The male of this species is unknown, but the terminalia are presumably similar to other species of the daciformis species group, as follows: Lateral surstylus very short, barely extended beyond prensisetae. Phallus extremely short, less than 0.30 mm long; glans absent.
