Abstract

Two individuals of wavy jaw slopefish, Cymatognathus aureolateralis, were collected from a fish landing area in the coastal municipality of Governor Generoso in Davao Gulf, Philippines. This extends the species’ known geographic distribution northward, approximately 579 kilometers from Bitung, North Sulawesi, Indonesia, where it was first described. The specimens collected from Davao Gulf have similar overall appearance, including the elevated tooth patch that is distinct for this genus. Morphological and meristic characters were also comparable with the measurements and counts provided for the specimen from Indonesia. Although interconnectivity of C. aureolateralis between southern Mindanao and North Sulawesi is possible given the similar bathymetric contour along the stretch of the Sangihe arc, larval transport remains unclear due to the prevailing oceanographic currents. The new records of marine fishes reported recently in Davao Gulf emphasizes the importance of strengthened management measures through an ecosystem-based approach to sustain biodiversity amid various anthropogenic threats.

在菲律宾达沃湾首次记录到波浪颌坡鱼，Cymatognathus aureolateralis (Acropomatiformes: Symphysanodontidae)

在菲律宾达沃海湾格内诺索总督沿海城市的一个鱼类上岸区采集到了两只波浪颌坡鱼--Cymatognathus aureolateralis。这将该物种的已知地理分布范围向北扩展，距离首次描述该物种的印度尼西亚北苏拉威西省比通（Bitung）约 579 公里。从达沃湾采集的标本具有相似的整体外观，包括该属特有的隆起齿斑。形态和分部特征也与印尼标本提供的测量和计数结果相当。虽然棉兰老岛南部和北苏拉威西之间的金线鲃有可能相互连接，因为桑吉河弧一带的水深轮廓相似，但由于洋流的影响，幼体的迁移情况仍不清楚。最近报告的达沃湾海洋鱼类新记录强调了通过基于生态系统的方法加强管理措施的重要性，以在各种人为威胁中维持生物多样性。
