Anastrepha daciformis Bezzi

Recognition
Anastrepha daciformis 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.  Anastrepha daciformis is one of three species with a wing pattern comprising only a narrow, uninterrupted, costal band (not covering all of cell r2+3), a distinct band covering crossvein DM-Cu, and a cubital streak not extended along vein Cu1 beyond BM-Cu.  It most closely resembles A. castanea and A. katiyari, which differ as follows:  A. katiyari with pale dorsocentral stripe connected anteriorly to pale area on postpronotal lobe; microtrichose only on and lateral to sublateral stripe, and on and posterior to expanded posterior part of medial pale stripe; occiput mostly yellow, usually with pair of small brown dorsal stripes; propleuron and base of syntergite 1+2 yellow; oviscape length 3.95-5.00 mm, 1.25-1.65 times mesonotum length. A. castanea with mesonotum with presutural lateral pale stripe reduced to pale spot on posterior part of notopleuron, absent from scutum; oviscape length 2.95-3.49 mm, 1.10-1.30 times mesonotum length; abdominal tergite 3 sometimes with small apical white band, tergite 4 without apical white band.  Anastrepha daciformis also has a larger M ratio than in both of those species.

Description
Body predominantly dark orange-brown to red-brown.

Head: Mostly yellow. Frons with brown transverse dorsal band, moderately broad, usually bilobed, broadest along eye margin where it extends anteriorly beyond level of orbital seta. Gena with large brown spot below eye. Occiput brown except anterior margin and sometimes narrowly dorsomedially, in teneral specimens brown only dorsally. Posterior orbital seta absent (of 22 specimens with intact head setae examined by Norrbom 1998, present on one side only on 1 female).

Thorax: Medial pale stripe bilobed or triangular posteriorly, not extended to dorsocentral seta. Presutural dorsocentral pale stripe isolated anteriorly from pale area on postpronotal lobe and not connected posteriorly to sublateral stripe along transverse suture. Presutural lateral pale stripe well differentiated, complete, including posterior part of notopleuron. Pleuron brown except following yellow areas: posterodorsal third of anepisternum; two small dorsal spots on katepisternum; katepimeron; anterior 2/3 of katatergite; and most of anatergite. Subscutellum and mediotergite entirely brown. Scutum microtrichose except for medial presutural bare area on and between dorsocentral stripes, at most extended halfway to transverse suture; notopleuron microtrichose; scutellum entirely microtrichose except for small basal area on side.

Wing: C- and S-bands completely fused along costa to form narrow, uninterrupted, brown to dark brown marginal band; in cell br not extended to vein M along cell bm; covering all of cell r1, but cells r2+3 and r4+5 hyaline except apically; apically narrow, separated from or occasionally extended to apex of vein M. S-band incomplete, middle part between veins R2+3 and Cu1 absent; basal part as dark as C-band but hyaline or very faintly infuscated in posterior third or more of cell bcu. V-band as dark as C-band, extended anteriorly at most slightly into cell r4+5; distal arm absent. Vein M strongly curved apically; M ratio 1.52-2.00.

Wing.

Abdomen: Tergites, including lateral margins, red-brown; except for male tergite 5, each with narrow apical pale band. Syntergite 1+2 also with small medial pale band; brown or orange basally.

Female terminalia: Oviscape length 2.12-2.70 mm, 0.75-0.98 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 1.79-2.20; tip needlelike, nearly circular in cross-section, finely serrate apically, length 0.11-0.15 mm, width 0.025-0.03 mm.

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