03C3FA6F2012FFFF22C355ADFE5177FA.taxon	diagnosis	Diagnosis Known from a single female deposited in ZIN. Type specimen small, brown, with slender build. Scutellum partly obscured by a glued wing, scutellar plate very narrow, dorsal surface of scutellum smooth. Anteroventral cavity of metapleura present. First flagellomere subequal to second, third flagellomere smaller than first two, fourth subequal to third. Front and middle legs missing. The poor condition of the type made its study inconclusive. The specimen is most similar to R. villosa due to the small, slender body and narrow scutellar plate, but differs in the proportion of antennal segments. No specimens similar to the holotype were found among the material examined from Western and Northern Europe or from the Macaronesian islands. We suggest that it is either a representative of an eastern species or an aberrant specimen of R. villosa.	en	Costa Baião, Guilherme, Forshage, Mattias (2018): Revision of the West Palaearctic species of Rhoptromeris Förster, 1869 (Hymenoptera: Figitidae: Eucoilinae).

03C3FA6F2013FFFF22D05296FE5170EE.taxon	diagnosis	Diagnosis Species known from female holotype, one paratype and two additional specimens, all deposited in MGAB. Body small, pale, stout, antennae and legs remarkably short. Globular head with broad genae. Anteroventral metapleural cavity present, posteroventral incision of metapleura absent. Elongate metasoma with lateral hairy ring. Holotype wings damaged, paratype wings missing. The stout body, short appendages and antennal characters suggest this species is most similar to Rhoptromeris heptoma or possibly a synonym of it. No specimens similar to the holotype were found among the material examined from Western and Northern Europe or from the Macaronesian islands. We suggest that the known individuals are either representatives of an eastern or rare species, or perhaps even aberrant specimens of R. heptoma.	en	Costa Baião, Guilherme, Forshage, Mattias (2018): Revision of the West Palaearctic species of Rhoptromeris Förster, 1869 (Hymenoptera: Figitidae: Eucoilinae).

03C3FA6F2013FFFA22A0558AFD9875BF.taxon	diagnosis	Diagnosis Head and mesosoma dark brown or black, female metasoma lighter, usually with reddish or orange tinge ventrally, 1.5 – 1.6 mm (Figure 3 a), male metasoma brown. The species can be distinguished from R. heptoma or R. villosa by the long and narrow marginal cell, elongate antennae and more strongly sculptured scutellum, and from R strobigena or R. koponeni by the long and narrow marginal cell, the medial bridge on the pronotal plate and the smaller eyes. Specimens show considerable variation in size of female flagellomeres, height of scutellum and sculpture of the dorsal scutellar surface. It is possible that future molecular studies or analysis of additional material will reveal that the species as conceived here can be split into two or more distinct species.	en	Costa Baião, Guilherme, Forshage, Mattias (2018): Revision of the West Palaearctic species of Rhoptromeris Förster, 1869 (Hymenoptera: Figitidae: Eucoilinae).

03C3FA6F200CFFE022E95285FB9373C9.taxon	diagnosis	Diagnosis This species shares with R. ru fi ventris and R. macaronesiensis sp. nov. the lack of the anteroventral cavity of the metapleura. It can be distinguished by the pronotal foveae separated by a medial bridge, larger eyes, broader wings and higher scutellum with relatively broad scutellar plate. Several studied specimens exhibited a mix of diagnostic characters of both R. nigriventris and R. ru fi ventris, and more extensive molecular studies could be useful to better elucidate the relationship between these species.	en	Costa Baião, Guilherme, Forshage, Mattias (2018): Revision of the West Palaearctic species of Rhoptromeris Förster, 1869 (Hymenoptera: Figitidae: Eucoilinae).

The species is most similar to R. macaronesiensis sp. nov., from which it can be distinguished by the absence of the posterior incision of the metapleura. R. ru fi ventris can further be separated from R. nigriventris by the pronotal fovea fused medially into a continuous furrow (separated by a medial bridge in R nigriventris), narrow scutellar fovea and very short scutellum.

03C3FA6F200EFFE222DC5291FC1F73C9.taxon	diagnosis	Diagnosis A common and remarkably variable species in terms of colouration, size, sculpture of scutellum and size of scutellar plate. It is possible that large-scale molecular studies will eventually reveal that the species as currently circumscribed comprises a complex of closely related species. The short female antennae with F 3 smaller than F 4 and the male antennae with almost straight F 2 separate R. villosa from all other Rhoptromeris species. The species can be further distinguished from R. heptoma by the slender femora, and from R. dichromata by the smooth scutellar surface.	en	Costa Baião, Guilherme, Forshage, Mattias (2018): Revision of the West Palaearctic species of Rhoptromeris Förster, 1869 (Hymenoptera: Figitidae: Eucoilinae).
