| 内容記述 | Four specimens of Pseudogobio agathonectris Tominaga and Kawase, 2019 (70.9–96.7 mm standard length) were collected from two tributaries of the Yamato River system, Nara Prefecture, Japan. These specimens were identified as the species based on the following characters: long mouth (35.9–43.3% of head length); long barbel (22.7–34.1% of head length), with the tip extending beyond vertical through anterior edge of eye; tip of outer edge of pectoral fin strongly curved posteriorly; tip of pectoral spiny soft ray not reaching that of 6th soft fin ray; 13 pectoral soft fin rays; short length between anus and anal-fin ori-gin (18.5–19.6% of standard length), with 10–12 scales; distinct dark blotches and obscure black spots on dorsal and lateral body. The present specimens represent the first specimen-based record of P. agathonectris from the Yamato River system. It remains unknown whether this species occurs naturally in the system. Freshwater fish species in the Yamato River system have been reduced by past environmental degradation, and appropriate conservation measures may be required for this species as well. If its presence is the result of artificial introduction via the Yoshino River diversion from the Kino River system, suitable management actions should be considered. | |||||
