03B14F40FFFCBD6FFFC418DE63C47EC3.taxon	discussion	Remarks Type specimen was collected from Madura Straits near Surabaya and Kammal, Java, Indonesia (AqGRISI, 2019). This species was first described as Gobius cyanomos by Bleeker in 1849. Later Ataur Rahman 1989 placed this species under Acentrogobius 7. Larson and Zafar, 2022 placed the species under the genus Aulopareia Smith, 1945. Presence of elongated infraorbital pore and absence of postorbital pore and presence of a single inter-orbital pore are the characters, which distinguishes Aulopareia from Acentrogobius.	en	Sen, Arya, Sreeraj, Chemmencheri Ramakrishnan, Raghunathan, Chelladurai (2023): First report of two euryhaline gobiid fishes (Gobiidae Cuvier, 1816) from West Bengal, India.

03B14F40FFFDBD68FFC41BF667CA7907.taxon	distribution	Distribution India: Godavari estuary in Andhra Pradesh (Rao, 1971). Elsewhere: Vietnam, Singapore (Venkateswarlu and Ramarao, 1986; Tan and Lim, 2019).	en	Sen, Arya, Sreeraj, Chemmencheri Ramakrishnan, Raghunathan, Chelladurai (2023): First report of two euryhaline gobiid fishes (Gobiidae Cuvier, 1816) from West Bengal, India.

03B14F40FFFDBD68FFC41BF667CA7907.taxon	discussion	Remarks This species can be differentiated from its commonly related species by its distinctive vertical sub-marginal bluish-black bar on the first dorsal fin and four dusky blotches on the side behind the anus, the rearmost blotch is almost joined to two similar blotches at the base of the caudal fin (Tran et al., 2013). Also, the transparent anal fin, truncated caudal fin and a smaller number of lateral line scales helps in the identification. Study of the specimens Collected from the type locality, i. e., from Coringa Wildlife Sanctuary of Godavary estuary, by the authors also supports the original description of the species and provides the fact of S. yanamensis being a valid species. The species was described as S. yanamensis by Visweswara Rao from the Godavari estuary in India (Rao, 1971). Talwar and Jhingran, (1991) discussed this species as a questionable synonym of S. minima Hora, 1923 without any suitable justification. Although the present study as well as the study by Larson and Hammer, (2021), gives justification of S. yanamensis to be a separate valid species. The holotype and six paratypes are held at the Zoology Museum, Andhra University, Waltair (Fricke et al., 2021). Larson H. K. on the revision of Stigamtogobius placed this species under Pseudogobius Popta, 1922; without much justification (Larson, 2005). Although it seems to be poorly known, the species was again recorded from the Mekong delta in Vietnam (Tran et al., 2013). From 17 years old survey of mangroves of Singapore, this species has been identified in 2019 (Tan and Lim, 2019). Recently in 2021, Larson & Hammer in the revision of Pseudogobius, again removed the species from this genus because it has a different setup of sensory canals and pores on its head and does not have the same characteristic corkscrew-shaped intestinal arrangement that is found in Pseudogobius (Larson et al., 2016). As well as the S. minima which was previously been confused with S. yanamensis is now placed under the genus Pseudogobius (Larson and Hammer, 2021). Still S. yanamensis has been recorded as a synonym of S. minima in World Register of Marine Species, accepted as a Nomen Dubium in Catalogue of Fishes and as a doubtful species from India by Parenti, (2021). Authors suggest that S. yanamensis should be accepted as a valid species following the current study (Rao, 1971; Larson and Hammer, 2021).	en	Sen, Arya, Sreeraj, Chemmencheri Ramakrishnan, Raghunathan, Chelladurai (2023): First report of two euryhaline gobiid fishes (Gobiidae Cuvier, 1816) from West Bengal, India.
