Original description	Long. 6 millim. - Viridi-cyaneus, abdominis dorso aurato, emarginatura triangulari, ultimi segmenti lateribus unisinuatis. Capite confertim et mediocriter punctato; prothoracis et mesothoracis punctis laevibus ac diffusis; scutelli et postscutelli validis et confertis. Postscustello sub hemisphœrico-truncato. - Sainte-Baume, sur les hêtres, très-rare. Diffère de tous les autres Omalus par l'incision triangulaire de l'abdomen; s'éloigne en outre de l'auratus par sa ponctuation plus serrée et les côtés du 3e segment ventral unisinués; du punctulatus, par l'impression faciale remontant plus prés des ocelles; de l'œneus, par ses pro et mesonotum ponctués; des pusillus et minutus, par son abdomen d'un doré cuivreux non douteux; du cœruleus, par sa couleur et sa forme plus élancée; du Wesmaëli, par son corps plus court et son postécusson non conique.

Notes on Hosts

Known Plants & Habitat

Plants for rest	Inula viscosa Ait. and Lavatera arborea L. infested by aphids, leaves of Ceratonia siliqua L., flowers of Euphorbia cyparissias L., Rubus (Invrea, 1922), flowers of Euphorbia (Schmidt, 1977)
Plants for refuge
Habitat
Parasites
Biological notes	Because Pseudomalus females have never been observed at the nest entrances of their hosts, the suggestion is that Pseudomalus species place their eggs on the body of aphids before they are collected by Pemphredoninae (Veenendaal, 2011)
