03DEA12FFF8DFFE9CFDEFF7D45BDFF77.taxon	description	The original specimens of acuminatus have not been studied, the identifications here being based on zur Strassen (2003) and on specimens in BMNH, London and ANIC, Canberra. The synonymy of parisae is based on the type specimens (Figs 7 – 15). One male listed but misidentified by Goldarazena (2013) as longistylosus has been re-examined. Contrary to that publication, this male has pore plates only on sternites III – VII, not on VIII. The species acuminatus shares with the two species previously placed in Nigritothrips the presence of tergal and sternal posteroangular setae slightly in front of the margins. This condition is also found in Rubiothrips parisae, resulting in the synonymy given above. In contrast, these setae are marginal in all the species previously placed in Rubiothrips. Females of the two species placed in Nigritothrips have antennal segments V and VI closely approximated, but this is less so for the males (Figs 3 – 4). The antennal segments also have fewer microtrichia than are found in acuminatus and other species here considered members of Belothrips.	en	Mirab-Balou, Majid, Mound, Laurence, Goldarazena, Arturo, Negiş, İnci Şahin (2025): The Palaearctic genus Belothrips Haliday (Thysanoptera: Thripidae), with new synonyms and new combinations.

03DEA12FFF8CFFE9CFDEFEA0430FFCF9.taxon	description	Bhatti provided an extensive description together with an impressive list of seven differences between his new species and the species described by Priesner. However, considering that these comparisons were based mainly on females, and that only one female of zurstrasseni is known, then some of these differences become unconvincing. This applies to the first two characters, the relative lengths of sense cones on antennal segments V and VI, and also to the fifth character — density of microtrichia on the antennal segments surface. The third and fourth characters listed refer to the relative lengths of segments VI and VII, but apply only to the holotype female and not to the two paratype males of zurstrasseni (Figs 1 – 4). Character state differences six and seven are also based on the single female and could be expected to be due to individual variation. As a result, it is concluded here that there is insufficient evidence to consider the holotype female of zurstrasseni as a different species from longistylosus, and the name is therefore listed as a synonym.	en	Mirab-Balou, Majid, Mound, Laurence, Goldarazena, Arturo, Negiş, İnci Şahin (2025): The Palaearctic genus Belothrips Haliday (Thysanoptera: Thripidae), with new synonyms and new combinations.

03DEA12FFF8CFFE9CFDEFC2D44EBFA3F.taxon	description	This species was based originally on a single female from Stockholm, but both sexes are distinguished from acuminatus in the key to European Terebrantia by zur Strassen (2003), who gives the distribution as “ Russia, Scandinavia, East Central Europe ”. The web site of the Senckenberg Museum indicates the presence of only a single slide of morio, but through the courtesy of Nikolai Ignatev of that Museum seven slides bearing the identification morio by zur Strassen were found in the Senckenberg collections (Fig. 16). These seven slides bear specimens from Finland, Sweden, Poland, Czech Republic and Western Canada, and this record of morio from Canada, Alberta, was published by Chiasson (1986: 53). However, Canada was not mentioned by zur Strassen (2003) although that record includes the only male of morio available. The character states used in the 2003 key to distinguish morio are far from robust, particularly considering the few specimens available all of which lack host data. The validity of the species will remain in doubt until further information becomes available, such as good population samples and host data.	en	Mirab-Balou, Majid, Mound, Laurence, Goldarazena, Arturo, Negiş, İnci Şahin (2025): The Palaearctic genus Belothrips Haliday (Thysanoptera: Thripidae), with new synonyms and new combinations.
