Doryctobracon maculatus Marinho, 2021

( Figs 11–16 View FIGURES 5–22 , 34 View FIGURE 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 View FIGURES 5–22 ); 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 View FIGURES 5–22 ). Mesopleuron almost completely black, mainly posteriorly, black color extending over mesosternum ( Fig. 12b View FIGURES 5–22 ) 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 View FIGURES 5–22 ). Propodeum with a short mid-anterior longitudinal carina followed by complete posterior areola ( Figs 15 View FIGURES 5–22 , 34a View FIGURE 34 ). Areola with rounded edges anteriorly, where two to three short carinae radiate on each side, weakening without reaching lateral longitudinal carina ( Figs 15 View FIGURES 5–22 , 34b View FIGURE 34 ); only one carina, posterior transverse carina of areola, reaches lateral longitudinal carina ( Figs 15 View FIGURES 5–22 , 34c View FIGURE 34 ). Within areola are two very weak longitudinal carinae, bending posteriorly ( Figs 15 View FIGURES 5–22 , 34d View FIGURE 34 ), and another transverse carina at base ( Figs 15 View FIGURES 5–22 , 34e View FIGURE 34 ). Metasoma with dark-brown to black crossbands (T3–T6) ( Fig. 16 View FIGURES 5–22 ). Fore wing 5.9–6.6 mm long, darkened (infumate); stigma, veins and bristles all dark brown ( Fig. 11 View FIGURES 5–22 ). Hind wing 3.8–4.8 mm long; ovipositor about 5.6–6.4 mm ( Fig. 11 View FIGURES 5–22 ) (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 View FIGURES 5–22 ). 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 View FIGURES 5–22 , 30 View FIGURES 24–33 ). 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 View FIGURES 5–22 ). In the illustrated key ( Marinho & Zucchi 2023), the image of D. fluminensis actually corresponds to D. maculatus .
