Additional material: Col. CF Baker (1ò and 5ñ) with the following QR codes: 00960262 (ñ), 00960464 (ñ), 00960565 (ñ), 00960598 (ñ), 00960742 (ñ) and 00960874 (ò); Col. Ashmead (1ñ) with the following QR code: 00960652.

Comments: According to Gillette (1896: 94), this species was described based on 24 females and 22 males. We located 4 males and 10 females in the NMNH from Ashmead and Baker’s collections; 3ò and 6ñ have similar labels to the ones of the Lectotype and a handwritten label with the word ‘type’. So, we assume these specimens belong to the typical series. Baker’s material mentioned in ‘Additional material’ probably belongs to the typical series too, but the ‘type’ label is missing.

Synergus punctatus has partially smooth mesopleurae (striae are not extended into the speculum) as all the species mentioned in this study. Synergus punctatus is closely related to S. gilletti because females of both species have head and body coloration entirely black, except for a light halo around the mouth; also, both sexes of these two species have frontal carinae, the mesoscutum with weak transverse carinae, the scutellum wrinkled with the circumscutellar carina not visible and the metasomal punctuation forming a wide band, amongst others (see the differences between these species in the diagnosis of S. gilletti ). On the contrary, S. punctatus mainly differs from S. cibriani , S. citriformis (= S. elegans ), S. laticephalus , S. longimalaris and S. striatifrons sp. nov. by having frontal carinae (absent in all these species), the mesosoma with a few weak transverse carinae (coriaceous or weakly imbricated in all these species), the circumscutellar carina not visible (visible in all these species), a wide band of micropunctures in the metasomal syntergite (no punctures or only forming a posterodorsal patch in all these species), and body coloration entirely black in females, except for a yellow and well defined halo around the mouth (other coloration in all these species).

Short description: Synergus punctatus is characterized by the following combination of morphological traits: in females, body and head black, except for a yellow and well-defined halo around the mouth ( Fig. 8a View Fig ); in males, head yellow except for a black spot in the vertex. Frons and vertex coriaceous, without punctures ( Figs. 6a, b, c View Fig ). Frontal carinae weak but visible, incomplete and not branched ( Figs. 6b, c View Fig ). Female antennae 14-segmented, F1 just slightly longer than F2 ( Fig. 6f View Fig ); in males, F1 about 1.4 times longer than F2, curved, medially excavated, more expanded distally ( Fig. 6b View Fig ). Mesoescutum ( Fig. 6d View Fig ) weakly but densely transversely carinated; notauli inconspicuous in the anterior third of the scutum; mesopleurae ( Fig. 6g View Fig ) transversely striated, speculum smooth. Scutellum ( Fig. 6d View Fig ) wrinkled; circumscutellar carina not visible. Metasomal syntergite punctuation forming a band, occupying the distal half of the syntergite and reaching the ventral part of metasoma; not incised dorso-distally ( Fig. 6h View Fig ). Tarsal claws with a small basal tooth ( Fig. 6e View Fig ). Radial cell closed, 2.5 times longer than wide.
