Referred material.

CUF - NKNY - O 06 - 1 (217 individuals; Figs 12 K , 17 E ).

Habitat.

Attached to hard substrates, mainly shells of oysters and gastropod molluscs and stalks of seaweed, as well as wooden piles and supports, bamboo, various objects installed under water on muddy beds for oyster culture, and buoys, in freshened closed inner parts of bays and estuarine coastal areas, from intertidal to subtidal zones ( Henry and Mclaughlin 1975; Chan et al. 2009; Kepel’ 2018).

Distribution.

Indian Ocean; Indo-West Pacific, from Japan to New Zealand ( Henry and Mclaughlin 1975; Puspasari et al. 2000; Jones and Hosie 2016). Records of fossils from the Pleistocene and Holocene in Japan ( Yamaguchi 1977 b; Karasawa and Kobayashi 2022).

Record in Thailand.

Gulf of Thailand ( Henry and Mclaughlin 1975; Puspasari et al. 2000).

Taxonomic remarks and comparisons.

The subfamily Amphibalaninae was erected to incorporate most of the species under the Balanus amphitrite complex / group ( Pitombo 2004). Currently, there are a total of six species from this subfamily recorded from Thailand: Amphibalanus amphitrite (Darwin, 1854) , A. reticulatus (Utinomi, 1967) , A. thailandicus ( Puspasari, Yamaguchi & Angsupanich, 2001), A. variegatus (Darwin, 1854) , Fistulobalanus kondakovi ( Tarasov & Zevina, 1957) , and F. patelliformis ( Bruguière, 1789) ( Henry and Mclaughlin 1975; Puspasari et al. 2000, 2001; Pochai et al. 2017). The presence of two or more rows of parietal tubes on shell walls assigns these specimens to the genus Fistulobalanus ( Zullo 1984; Chan et al. 2009). We attribute these specimens to F. kondakovi because of the smooth outer surface of shells without any longitudinal ribs ( Henry and Mclaughlin 1975; Chan et al. 2009; Kim 2011; Kepel’ 2018).
