Abstract

Combtooth Blennies (Blenniiformes: Blenniidae) are small, cryptic coastal fishes that are often underrepresented in regional ichthyofaunal surveys. Lampung Province, located at the southern tip of Sumatra, encompasses diverse coastal habitats suitable for blenniid fishes; however, information on their occurrence remains limited. Here, we present preliminary records of Combtooth Blennies from Lampung Province, based on field observations and photographic documentation conducted between 2017 to 2025, complemented by verified citizen-science records. A total of seven taxa representing five genera were recorded, including Alticus saliens. Aspidontus taeniatus, Entomacrodus vermiculatus, Istiblennius sp., Istiblennius dussumieri, Salarias sp. and Salarias fasciatus. Records were obtained from multiple coastal districts and habitats, including rocky intertidal zones, shallow reefs and nearshore coastal areas. Istiblennius dussumieri was the most frequently recorded species and was widely distributed across the study area. The findings provide essential baseline data on the distribution of Blenniidae in Lampung Province, emphasizing the importance of targeted surveys alongside citizen-science initiatives for documenting cryptic coastal fish diversity in southern Sumatra.

Abstract

This study reports the first confirmed record of Zenarchopterus gilli from Lampung Province, southern Sumatra, Indonesia, based on field surveys conducted on 7 November 2025 in the Petengoran Mangrove Area, Pesawaran Regency. Several individuals were observed in shallow estuarine waters along mangrove creeks and tidal channels, and species identification was verified through diagnostic morphological characters, including the elongated lower jaw and distinctive modifications of the male anal-fin and dorsal-fin rays. The specimens conform to published descriptions of Z. gilli. Previously, the species had been recorded from northern Sumatra, Java, Bali, Lombok, Kalimantan, Sulawesi, Halmahera, Komodo, Maumere and Raja Ampat, but not from Lampung. This new record fills a geographic gap in its distribution in western Indonesia and suggests that the species likely has a broader and continuous coastal distribution across Sundaland, highlighting the need for further surveys in underexplored estuarine and mangrove habitats.
