Baltimorda succinea ( Bao, Walczyńska, Bojarski, Jarzembowski, Wang & Rust, 2018) comb. nov.

Tomoxia succinea Bao, Walczyńska, Bojarski, Jarzembowski, Wang & Rust, 2018: 32 . Holotype and paratype: Baltic amber.

Comments on identification. The examination of figures and description of Tomoxia succinea provided by BAO et al. (2018) indicates that this species is not associated with the genus Tomoxia , because this placement is based on erroneous arguments and poor knowledge of the generic delimitations within the Mordellini . The diagnosis they provide is as follows: ‘Diagnosis (emended). The diagnostic characters for the genus Tomoxia when compared to the other members of the tribe Mordellini are: (1) eyes finely granulated; (2) scutellum quadrilateral or irregular shaped; (3) hind tibia with a fine dorsal ridge and a lateral ridge; basal tarsomere of hindleg also with a fine dorsal ridge (SMITH 1882, LILJEBLAD 1945, FRANCISCOLO 1965, JACKMAN & LU 2001).’ While points (1) and (2) do not provide any information relevant to the definition of the genus (e.g., eyes with small facets are present in all three genera included in the informal Tomoxia complex ( HORÁK 2007) and in many other Mordellini ), point (3) is incorrect per se because in Tomoxia , a dorsolateral ridge (dorsal ridge sensu BAO et al. 2018) is present on the metatibia, but absent on the first metatarsomere.According to the generic key to the Tomoxia complex provided by HORÁK (2007), the genus Tomoxia is defined as follows: ‘Hind tibiae besides preapical ridge with fine dorsolateral ridge. First tarsomere of posterior tarsus without dorsolateral ridge. Eyes very finely facetted, with interfacetal setae.’ In the description of eyes of Tomoxia succinea the authors stated those are ‘large, ellipsoidal, finely faceted and granulated, apparently not reaching occiput, hairy.’ This term likely indicates the presence of interfacetal setae, which are present in Tomoxia and Tomoxioda , but absent in Paratomoxioda . The combination of eyes with small facets covered with setae and presence of dorsolateral ridges on hind tibia and first metatarsomere conforms with the diagnosis of the genus Klapperichimorda Ermisch, 1968 , which contains four Oriental species ( ERMISCH 1968; HORÁK 1996, 2020).

Because of the uncertain generic identity of the holotype and paratype of Tomoxia succinea , this species is transferred here into Baltimorda new collective group.
