Synophromorpha Ashmead, 1903

Type species.

Synophrus sylvestris Osten Sacken, 1861.

Diagnosis.

Mesoscutum generally less coarsely sculptured, appearing mostly or entirely coriaceous, less pubescent, and with some strong setigenous punctures. Notauli complete, strong throughout. Fore wing with marginal cell open. Metasoma with syntergite in females but with all tergites free and articulating in males.

Note.

Synophromorpha is represented by four species in North America, all of which are inquilines of Diastrophus species associated with Rubus L. Ritchie and Shorthouse (1987) described the species S. kaulbarsi Shorthouse & Ritchie, 1987 from a single specimen collected in Mexico; they speculated that this species was evidence of undiscovered Mexican Diastrophus or represented the use of an alternative host such as an oak gall wasp.
