Some specimens from Madagascar, 16°24.24’S 45°18.36’E, are more darkened, with part of occiput and entire mesopleuron and metapleuron brown. Occasionally mesosoma testaceous, except mesoscutum, mesoscutellum, part of mesopleuron and median region of propodeal declivity brown. In specimen from Madagascar, 16°41.49’S 44°31.41’E, head black, except mandible, clypeus, part of malar space and stripe between antennal toruli ferruginous-dark; antenna brown, except scape and pedicel testaceous; prothorax ferruginous-dark; mesoscutum totally black; rest of mesosoma black; metasoma brown; legs testaceous. In specimen from Madagascar, 23°13.351’S 43°52.853’E, head black, except mandible, clypeus, malar space and stripe along orbits testaceous, area between antennal toruli ferruginous-dark; antenna brown, except antennomere 1 testaceous; mesosoma black, except prothorax (dorsally brown), posterior third of mesoscutum and basal third of metapleuron testaceous; metasoma brown; legs testaceous. In specimen from Madagascar, 21°13.11’S, 45°19.26’E, head and mesosoma completely testaceous-reddish, except ocellar triangle and axilla brown.

Head dull, convex, granulate and slightly rugose; frontal line absent; occipital carina complete; POL = 5.5; OL = 2; OOL = 6; OPL = 1; TL = 4; greatest breadth of lateral ocelli longer than OL (4:2). In dark specimens head with some irregular keels on frons. Mesoscutum dull, as sculpured as head (in dark specimens mesoscutum with some irregular keels). Notauli complete, posteriorly separated; minimum distance between notauli as long as greatest breadth of lateral ocelli (4:4), shorter than breadth of each lateral region of mesoscutum measured at posterior margin of mesoscutum ( Fig. 159B ); in two specimens from Madagascar, 21°15.05’S 47°24.43’E, minimum distance between notauli longer than greatest breadth of lateral ocelli (4:3). Mesoscutellum shiny, punctate, unsculptured among punctures. Metanotum shiny, unsculptured. Metapectal-propodeal disc reticulate rugose, without strong transverse posterior keel; propodeal declivity reticulate rugose, without longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (19:14); 2R1 cell open.

Hosts. Unknown.

Distribution. Madagascar, Mayotte.

Remarks. It is possible that Thaumatodryinus merinus is the opposite sex of T. dentatus Benoit (because one ♀ and six ♂♂ have been collected in the same site in Mahajanga, 18°01’35’’S 44°03’02’’E, and 1 ♀ and 7 ♂♂ have been collected in the same site in Antsiranana, Bekaraoka Forest, 13°10.00’S 49°42.36’E).
