Notes on type specimens of Rhinogobius flumineus (Mizuno 1960) (Perciformes: Gobiidae) and Cobitis takatsuensis Mizuno 1970 (Cypriniformes: Cobitidae) in Tokushima Prefectural Museum, Tokushima, Japan Author Ito, Taiki Tokushima Prefectural Museum, Hachiman-cho, Tokushima 770 - 8070, Japan Author Suzawa, Yuzuru Institute of River Biology Ltd., Hinosato, Munakata, Fukuoka 811 - 3425, Japan Author Sato, Yoichi Tokushima Prefectural Museum, Hachiman-cho, Tokushima 770 - 8070, Japan text Zootaxa 2024 2024-05-02 5446 4 564 572 http://dx.doi.org/10.11646/zootaxa.5446.4.8 journal article 10.11646/zootaxa.5446.4.8 1175-5326 11102244 D2B1309F-CA37-485B-B5CD-4478CDA196D4 Rhinogobius flumineus (Mizuno 1960) ( Figs. 4 – 7 ) Holotype : TKPM-P 3000 , female, 37.0 mm SL, Sojya-gawa River , Oshita , Ochi District , Ehime , Japan , 31 August 1959 , N. Mizuno. Paratypes : All paratypes collected with holotype. TKPM-P 3001 , female, 34.2 mm SL ; TKPM-P 3002 , male, 33.5 mm SL ; TKPM-P 3003 , male, 32.3 mm SL ; TKPM-P 3004 , male, 38.2 mm SL ; TKPM-P 3005 , female, 34.3 mm SL . Remarks. Mizuno (1960b) noted that while he had preserved the type specimens of the species in “my collection,” each type specimen had not been individually assigned a number. After TKPM received these type specimens, TKPM-P registration numbers were assigned to the holotype and five paratypes . Specimen jars containing the holotype and paratypes were labeled with their type status, localities, and collection dates. The collection date indicated on these jar labels was 31 August 1959 , whereas Mizuno (1960b) erroneously described the collection date of the holotype and paratypes as 30 August 1959 . In Mizuno (1960b) , neither the vertebral count nor details of the cephalic sensory system of each of the type specimens of R. flumineus were provided. Herein, in Fig. 6 , we present an illustration of the cephalic sensory system of the holotype , as well as the vertebral counts (abdominal + caudal) of the holotype and five paratypes as follows: TKPM-P 3000 : 11+17, TKPM-P 3001 : 11+16, TKPM-P 3002 : 11+17, TKPM-P 3003 : 11+17, TKPM-P 3004 : 11+17, TKPM-P 3005 : 11+17.
