( Figs 1 A–H View FIGURE 1 , 2 A–E View FIGURE 2 )

Diagnosis. Doryctobracon maculatus sp. nov. is readily separated from the other species of Doryctobracon , as it is the only species with dark-brown to black spots on the head, lobe of mesoscutum, mesopleura, mesosternum and dorsal metasoma ( Fig 1A–G View FIGURE 1 ). Besides the dark spots on the body, D. maculatus is also distinguished from the species of group 1 (areolate propodeum), namely D. areolatus , D. adaimei , D. fluminensis and D. whartoni .

Type material. Holotype. Female (ESALQENT0261), Brazil, São Paulo, Piracicaba, 23-III-2006, reared from larva of Anastrepha pseudoparallela (Loew) in sweet passion fruit ( Passiflora alata Curtis ), coll. Wyratan S. Santos. Paratype with same data as holotype, 1 female (ESALQENT0262); 2 females (ESALQENTO263 and 581), São Roque, SP, 31.III.2000, reared from larva of Anastrepha pseudoparallela (Loew) in sweet passion fruit ( Passiflora alata Curtis ), colls. Miguel F. Souza-Filho and Adalton Raga.

Female. Length of body, excluding ovipositor, 5.7–6.7 mm.

Head. 1.4–1.5 × wider than long; 1.2–1.3 × wider than width of mesoscutum; face polished and shiny, distinctly setose, weakly punctate; midridge smooth, weakly developed ( Fig 2A View FIGURE 2 ); distance between toruli equal to distance from torulus to eye. Antenna longer than body, 7.7–9.7 mm in length, with 58 to 60 flagellomeres; first flagellomere about 0.9–1.0 × length of second flagellomere, 1.4–1.8 × longer than wide. Eyes large, 1.2–1.3 × wider than high ( Fig 2A View FIGURE 2 ); in dorsal view, eye 1.7–1.8 × wider than temple width; in lateral view 2.1–2.2 × longer than temple length; malar space 0.4–0.5 × eye height. Clypeus 2.7–4.0 × wider than high, sinuate with median lobe on ventral margin, polished, obscuring labrum, with sparse setae, two to three times longer than setae on face ( Fig 2A View FIGURE 2 ).

Mesosoma. 1.3–1.5 × longer than high; 1.8–1.9 × longer than wide; 1.2–1.4 × higher than wide. Pronotum not visible dorsally; median lobe and lateral lobes of mesoscutum polished, shiny, with few sparse bristle-like setae; notaulus smooth, complete, deeper anteriorly and shallower posteriorly, converging in large impression without midpit ( Fig 2B View FIGURE 2 ); scutellar sulcus divided into two large pits by median longitudinal carina; scutellum smooth with small punctures, margins setose ( Fig 2B View FIGURE 2 ); mesopleuron shiny, smooth, without longitudinal impression; propodeum with anterior median longitudinal carina (0.11–0.14 mm) followed by complete posterior areola; anteriorly, on both sides of areola, small transverse carinae radiate without reaching lateral longitudinal carina (only one, which appears at midpoint of areola, reaches lateral longitudinal carina). Many bristle-like setae coincide with the carinae, from center, anteroposterior region and base of propodeum and metapleura ( Figs 1F View FIGURE 1 , 2D View FIGURE 2 ).

Metasoma. 1.9–2.2 × longer than wide and 1.0–1.6 × wider than high; length of T 1 0.8–1.0 × greater than width at apex; T 1 apex about 1.3–1.5 × width at base; tergum completely smooth, polished and shiny ( Figs 1G View FIGURE 1 , 2C View FIGURE 2 ); T 1 with two parallel dorsal keels, just above spiracles, well developed at base but indistinct posteriorly ( Figs 1G View FIGURE 1 , 2C View FIGURE 2 ); spiracles just before midpoint of T 1; ovipositor about 5.6–6.4 mm long; ovipositor sheath twice as large as metasoma; ovipositor with one subapical dorsal node and ventral serrations, similar to D. areolatus ( Fig 2E View FIGURE 2 ).

Wings. Fore wing infumate, stigma, veins and setae dark brown, 5.9–6.6 mm long; stigma 3.5–3.7 × longer than wide, with vein r slightly projecting from its midpoint; (RS+M)a 1.2–1.4 × longer than 3RSa; 2RS 1.1–1.2 × longer than 3RSa, 1.3–1.4 × longer than 1m-cu and 2.0–2.2 × longer than r-m; 1m-cu directly in line with 2RS; 3RSa 2.0–2.5 × longer than vein r; 2M 1.7–1.8 × longer than 3RSa ( Fig 1H View FIGURE 1 ). Hind wing 3.8–4.8 mm long, m-cu present and distinctly pigmented ( Fig 1H View FIGURE 1 ).

General coloration. Head and mesosoma orange or reddish orange. Head with black to dark reddish-brown spot resembling dorsomedian band posterior to toruli, which widens as band surrounding the ocellar triangle, vertex, and reaching occiput ( Fig 1B View FIGURE 1 ); mandibles orange with black apex; pronotum with dark red-brown spots on anterolateral margin, close to propleura, and posteriorly close to scutellum, which gradually fade to orange-red tones and, finally, orange in the center ( Figs 1A, 1D View FIGURE 1 ); mesoscutum with median mesonotal lobe with semi-oval black spot; lateral mesonotal lobes with broad black bands that reach anterolateral region of scutellum ( Fig 1C View FIGURE 1 ); mesopleuron with anterior dorsoventral third reddish orange, and posterior margin light orange, remaining part completely black, reaching and involving mesosternum ( Figs 1D, 1F View FIGURE 1 ); propodeum, metapleura, labial and maxillary palps light yellow; front and median legs with apical tarsomere black ( Fig 1A View FIGURE 1 ); hind legs dark-brown to black except coxa yellow with small smoky dark-brown spots, posterior third of femur orange to orange-red, external anterior region of tibia with small round orange area, posterior extremities of trochanter and tarsi red-orange ( Figs 1A, 1E View FIGURE 1 ); metasoma T 1, T 2 and sternum yellow, terga T 3 to T 6 with dark-brown to black crossbands ( Fig 1G View FIGURE 1 ) (only one specimen, from São Roque, showed color variation, i.e., dark mark between dorsal carinae of pronotum laterally and on T 1 posteriorly); ovipositor sheath dark brown, ovipositor red-orange ( Fig 1A View FIGURE 1 ); scape, pedicel and flagellomeres dark brown, anellus red-orange ( Fig 1A View FIGURE 1 ); and tegulae reddish-orange ( Fig 1C, 1D View FIGURE 1 ). Fore wing and hind wing infumate; stigma, veins and setae dark brown ( Fig 1H View FIGURE 1 ).
