Illustration for a comparative ecophylogenetic analysis of local myrmecofaunas, based on r/K selection theory and intra / interspecific parabiosis / lestobiosis, particularly focused on allochthonous and invasive species.

[Opius Wesmæl 1835: 33 (IT: 18) sgg, 1,202 (IT: 84) spp]

Cfr. notes¹ over the above image.

Opius is the largest genus in Opiinæ (39 gg, 2,061 spp), recognized primarily by asymmetrical (excluding ventrobasal carina) more or less abruptly widened mandibles. Solitary koinobiont ovilarval endoparasitoid of Agromyzidæ, Anthomyiidæ, Drosophilidæ, Tephritidæ, Ephydridæ, Cecidomyiidæ; emergence of imago from host puparium. This specimen belongs to the plausibly nonmonophyletic taxon Phædrotoma, often treated as Opius sg or as distinct genus, without widened mandible base. After several hours using different keys it couldn't be identified up to sp level; it is likely a species nova to be described in upcoming revisions. Even in M. Fischer NHMW collection, 3 different spp may be present under 1 common sp; selected references give an impression about direction to revise this genus. Opius exiguus is very common but also a waste bin taxon to some degree. Compared to this specimen, it has different mesosoma (pronope, no medioposterior mesoscutal depression), leg colour, shape of venation and 1st tergite.
