Type species. Electrostephanus petiolatus Brues, 1933 .

Diagnosis. Male: Body of moderate-size (ca. 9 mm); slender. Antenna with more than 20 articles (23 in type species). Metacoxa without dorsal tooth; ventral surface of metafemur with three principal teeth, one blunt tooth near base, one larger blunt tooth near midlength, and one blunt tooth near apex, with seven minor, blunt teeth between principal teeth; tarsi pentamerous; pretarsal ungues simple; arolium present. Forewing with long, arched basal vein; vein Rs+M b absent; bullae absent; 2Cu a and 2Cu b present and tubular; 2A, 3A, and 2cu-a nebulous; hind wing with only Sc+R present. First metasomal terga and sterna elongate, about five times longer than wide, but distinctly separate (not fused as in Stephaninae , such as Denaeostephanus Engel & Grimaldi , also in Baltic amber), thus forming “pseudo-petiole”, pseudo-petiole nearly as long as mesosoma; gaster slender, not distinctly thickened relative to pseudo-petiole, width gently tapering along its length. Female: Unknown.

Etymology. The new genus-group name is a combination of Electrostephanus and an adjectival derivative of eidos (Greek, meaning, “kind” or “having the form of”). The name is masculine (while generic words ending in the noun eidos are neuter, those ending in the adjectival derivatives, such as – odes or – oides, may be in practice any gender [masculine, feminine, or neuter]: Brown, 1954).
