Distribution. Mediterranean species (for details see REGALIN & MEDVEDEV 2010b).
Comments. Tituboea biguttata is one of the most common and widespread Mediterranean clytrines with extensive variability of dorsal pattern. This species evidently forms many local populations which can slightly differ also in the shape of the aedeagus and male protarsi.
The type material of T. biguttata was not traced in MNHN and its deposition is unknown. However, there is no doubt about the identity of the species based on the description (OLIVIER 1791) and colour picture in OLIVIER (1808).
The type material of var. vagenotata was not found in MNHN and the deposition is unknown to us. We left this taxon in synonymy with T. biguttata.
According to KOCHER (1959: 9, note 2), A. tredecimpunctata var. ssavipennis was described based on one female (holotype) deposited in Institut scientiħque chériħen in Rabat. In PJCJ only non-type specimen mentioned by KOCHER (1959: 12) was found. However, there is no doubt about its synonymy with Tituboea biguttata.
Antipa biguttata var. legionis was described in a publication containing also descriptions of subspecies (KOCHER 1959), thus it became infrasubspeciħc according to Article 45.6.4 of the Code (ICZN 1999). Two original specimens are deposited in PJCP and bear ‘holotype’ and ‘paratype’ labels, but these were added later by Jolivet (Jolivet, pers. comm. 2014). This variety is conspeciħc with T. biguttata.
The type series of A. bicoloripes is split into two parts: two syntypes are placed in Pic ̓ s collection and additional three syntypes are in Peyerimhoff ̓ s collection. The colouration of the specimens, particularly on pronotum, resembles that of T. tredecimpunctata, however examination of aedeagus conħrmed that A. bicoloripes is conspeciħc with T. biguttata. Protarsi I in the male syntypes of A. bicoloripes are slightly shorter than in typical T. biguttata, however we think that such difference can occur in local marginal population of this widely distributed species. Antipa bicoloripes was described twice based on the same type specimens (PIC 1942a,b), thus, both names are objective synonyms and are also proposed as new synonyms of T. biguttata.
