Remarks.

Goniozus Förster is the second most speciose genus in Bethylinae , being composed by 174 described species, three of them representing fossil taxa, two from Baltic amber and one from Dominican amber ( Azevedo et al. 2018). Its species are distributed around all zoogeographic regions. The taxonomic efforts for this genus are represented by a species revision for the Nearctic region (Evan, 1978), in which nine species groups were recognized; and a species revision for the Sino-Japanese region ( Terayama 2006). The latest phylogenetic work for this group, published by Ramos and Azevedo (2020), included the largest representation of the diversity within Goniozus , and retrieved it as a paraphyletic group, a result also found here. Based on this result, Ramos and Azevedo (2020) reinforced the necessity to further investigate its constituent groups in order to better delimit the genus, based on the morphological evidence.

The fossil fauna of Dominican amber is interpreted here as containing two species of Goniozus . In addition to † G. respectus , described by Sorg (1988), we also transfer the taxon † Pterosclerogibba antiqua , described by Olmi (2005) as a sclerogibbid wasp, to Goniozus (see below).
