Anastrepha martinsi , new species

Fig. 8

Diagnosis. Anastrepha martinsi can be recognized by the following combination of characters: aculeus 4.08–4.87 mm long; aculeus tip 0.26–0.32 mm long, apical 0.56–0.66 serrate with minute serrations, serrate part gradually tapered ending in a sharp apex, basal to serrate part slightly narrowed; denticles of eversible membrane fine, long and very numerous in trapezoidal pattern. In the key of Zucchi (2000), martinsi runs to mixta, from which differs in having the serrate part of the aculeus tip less extensive and S-band with vertex wide, extending from vein R4+5 to M. If the C- and S-bands are separated, in the key it runs to consobrina which differs in having the aculeus shorter and the serrate part less extensive.

Description. Mostly yellow to pale brown. Setae dark brown.

Head: Pale brown, except blackish ocellar tubercle. Facial carina, in profile, concave. 4–6 (usually 4) frontal setae; 2 orbital setae well developed, posterior seta slightly more slender than anterior one; ocellar setae brown, minute, weak. Setae black.

Thorax: Integument mostly yellow to pale brown with following areas white: postpronotal lobe; paired sublateral scutal vitta from transverse suture to posterior margin; and entire scutellum. Subscutellum and mediotergite entirely pale brown. Mesonotum 3.1–3.5 mm long. Scutum entirely microtrichose, including postpronotal lobe and scutellum; setulae golden. Setae red brown to dark brown ( Fig. 3b ). Katepisternal seta small, weak and pale brown.

Wing ( Fig. 8a ): Length 7.89–9.14 mm, width 3.5–4.19 mm. Crossvein DM-Cu 1.32–1.61 mm. Section of vein M between BM-Cu and R-M 1.7–2.2 times as long as section between R-M and DM-Cu. Section between R-M and DM-Cu 0.7–0.9 times as long as DM-Cu. Veins dark brown. Vein M curved apically, not reaching S-band, cell r4+5 0.84–1.01 times as wide at apex as at level of DM-Cu. Pattern mostly orange and moderate brown. Pterostigma moderate brown. C- and S-bands narrowly (the hyaline area is not constricted) connected (Espírito Santo specimens) or separated (Bahia female) along vein R4+5. V-band complete and separated from S-band, vertex wide, extending from vein R4+5 to M.

Abdomen: Pale brown. Tergites without markings, entirely microtrichose; setulae red brown.

Female terminalia ( Fig. 8c–d ): Oviscape 4.1–4.9 mm long, 1.13–1.36 times as long as mesonotum, entirely microtrichose; spiracle at basal 0.8–0.9 mm. Eversible membrane with numerous slim, long denticles in trapezoidal pattern. Aculeus 4.08–4.87 mm long; in ventral view base expanded, 0.2 mm wide; shaft 0.10 mm wide at midlength, sides parallel; tip 0.26–0.32 mm long, apical 0.56–0.66 serrate with minute serrations, serrate part gradually tapered to sharp apex, elongate triangular, basal to serrate part slightly narrowed, gradually broadening to 0.09–0.12 mm wide at cloacal opening. Spermathecae pear-shaped, about 0.1 mm wide (broadest diameter), moderately sclerotized, with outer surface covered by V-shaped spines ( Fig. 8e ). Egg white, slightly curved, 1.85 mm long, in straight line, gradually tapered from micropylar (anterior) to nonmicropylar (posterior) end ( Fig. 8f ).

Discussion. This species has a long aculeus tip, with more than the distal half minutely serrate, this being considered as a possible synapomorphy for the pseudoparallela species group (Norrbom et al. 1999). Furthermore, this species shows several characteristics similar to other species of this group. The eversible membrane denticles are slim, long and numerous, as in A. consobrina (Loew) , although different from the latter by the arrangement of the denticles, these being in a triangular pattern in A. consobrina and trapezoidal in the new species ( Fig 8d ). The vertex of the V-band is wide, extending from vein R4+5 to M, as observed in A. consobrina , A. dissimilis , A. lutzi and A. pseudoparallela ( Fig 8a ). The pear-shaped spermathecae are similar to those of A. consobrina , A. dissimilis and A. pseudoparallela , and the eggs are shaped like those of A. pseudoparallela . Nevertheless, A. martinsi can be distinguished from these species mainly by having a narrower aculeus tip, basal to the serrate part slightly narrowing, and by the minute serrations, i.e., much smaller than those of the above species.

Distribution. Known from the states of Espírito Santo and Bahia, Brazil.

Host. Unknown.

Comments. Specimens from Bahia have the C- and S-bands separated along vein R4+5.

Etymology. This species is named for David dos Santos Martins, collector of the species, who has carried out intensive surveys of fruit flies throughout Espírito Santo state.
