description: Doryctobracon maculatus Marinho, 2021
(Figs 11–16, 34)
Description. Body length (female), excluding ovipositor, 5.7–6.7 mm. Antenna with 58–60 flagellomeres. Head orange, with uninterrupted black or dark reddish brown spot or stripe that occurs on frons and vertex (ocellar triangle) and ends on occiput (Figs 12a, 13); lobes of mesoscutum with well-defined pitch-black spots, located at ends of lobes, being widely separated by orange color of mesosome; spot on median lobe is semi-oval, and lateral lobes are wide black bands that reach anterolateral region of scutellum (Marinho et al. 2021) (Fig. 14). Mesopleuron almost completely black, mainly posteriorly, black color extending over mesosternum (Fig. 12b) except for longitudinal groove on ventral surface of mesothorax (mesodiscrimen), which is orange. Hind coxa yellow with three small dark-brown smoky spots, arranged circularly (Fig. 12c). Propodeum with a short mid-anterior longitudinal carina followed by complete posterior areola (Figs 15, 34a). Areola with rounded edges anteriorly, where two to three short carinae radiate on each side, weakening without reaching lateral longitudinal carina (Figs 15, 34b); only one carina, posterior transverse carina of areola, reaches lateral longitudinal carina (Figs 15, 34c). Within areola are two very weak longitudinal carinae, bending posteriorly (Figs 15, 34d), and another transverse carina at base (Figs 15, 34e). Metasoma with dark-brown to black crossbands (T3–T6) (Fig. 16). Fore wing 5.9–6.6 mm long, darkened (infumate); stigma, veins and bristles all dark brown (Fig. 11). Hind wing 3.8–4.8 mm long; ovipositor about 5.6–6.4 mm (Fig. 11) (details in Marinho et al. 2021).
Distribution. Piracicaba and São Roque, São Paulo State, Brazil (Marinho et al. 2021).
Fruit fly and associated plant. Anastrepha pseudoparallela (Loew) in passion fruit (Passiflora alata Curtis, Passifloraceae) (Marinho et al. 2021).
Specimens examined. Holotype (female) (ESALQENT0261) and paratypes (3 females) (ESALQENT0262–263 and 581).
Comments. Only the type material is known. Doryctobracon maculatus is easily separated from other species of Doryctobracon by the black spots on the median and lateral lobes of the mesoscutum (Fig. 14). Despite this species having been described as the first of the genus to have this characteristic, D. fluminensis was previously characterized by Lima (1938) as having similar black spots (Figs 8, 30). However, the shape of these spots in the two species separates them, as discussed above. Other characters in D. maculatus and D. fluminensis that easily separate the two species are the mesopleuron, head, hind coxa, and propodeum (detail in notes, D. fluminensis). In general, D. maculatus is characterized by having many black spots on the body, such as on the vertex, pronotum, hind legs, and dorsal bands of the metasoma (T3 to T6) (Figs 11–16). In the illustrated key (Marinho & Zucchi 2023), the image of D. fluminensis actually corresponds to D. maculatus.
