Diagnosis. Eurygenys bilbo is a small testaceous species with darker mesosoma characterized by very long antennae and a dense mesosomal pilosity which hides the propodeum sculpture.

Description. FEMALE. L: 8.7.

Head. Strongly constricted behind eyes. Temples short and rounded. Frons shagreened, matt. Face and clypeus densely punctate-shagreened with dense white hairs, punctures confluent. Clypeus subtriangular without distinct transverse carina (Ci = 1.4). Malar space short (MLMi = 0.7). Maxillar and labial palpi with 4 and 3 segments respectively. Antenna 1.3x longer than body, with 57 flagellomeres.

Mesosoma . Entire mesosoma densely covered with long white hairs. Mesonotum and all pleurae deeply and densely punctate-shagreened. Speculum smooth. Propodeal carination coarse, hidden by long white hairs: basal carina incomplete, apical carina complete but centrally indistinct, longitudinal carinae absent. Propodeal apophyses well developed. Propodeal spiracles ovale. Tarsal claws basally pectinate.

Metasoma. Smooth. Tergite II narrow, about 4x longer than wide, the following tergites strongly compressed. Glymma absent. Ovipositor short (OTi = 0.5).

Color. Orange: head, mesosoma , base of metasoma and legs testaceous, antennae distal of article 9, second and following tergites, orange. Fuscous: occiput, mesosternum, speculum, scuto-scutellar groove, tegula, base of propodeum and postpetiole. Wings slightly infuscate apically, pterostigma elongated, light brown.
