F74987AEFFABFFEC38C4FB75FD83BB0F.taxon	discussion	Remarks Luciogobius chaojinensis sp. nov. is more similar to Luciogobius opisthoproctus Chen & Liao, 2024 than it is to any other congeneric species. However, Luciogobius chaojinensis sp. nov. can be well distinguished from the closely related species, Luciogobius opisthoproctus, by the following features: (1) anal fin rays I / 11 vs. I / 12; pectoral fin rays 13 vs. modally 11; (2) pectoral fin with one upper free rays vs. none of them; (3) vertebral count: 41 vs. modally 43; and (4) specific coloration: head in lateral side with densely-set of small brown spots superficially (around 60 – 95, higher count in male) vs. with very few brown to black spots (8 – 10); pectoral fin base: in having several brownish black spots vs. entirely spotless. It is quite possible that we will see more undescribed species with a slender form in the cryptic habitats of Taiwanese waters in the near future.	en	Chen, I-Shiung, Ren, Yu-Ting, Jiang, Guo-Chen, Wang, Shen-Chih, Chang, Chih-Wei (2024): Three new species of Luciogobius Gill (Teleostei: Gobiidae) from Taiwan.

F74987AEFFAFFFE138C4FBBCFBA5BC27.taxon	discussion	Remarks Luciogobius huatungensis sp. nov. is more similar to Luciogobius grandis Arai, 1970 than it is to any other remaining congeneric species. However, Luciogobius huatungensis sp. nov. can be well distinguished from its closely related species, Luciogobius grandis, by the following features: (1) pectoral fin rays modally 14 vs. modally 15; with one lower free ray vs. two of them; (2) vertebral count: 17 + 22 = 39; and modally 18 + 23 = 41; and (3) specific coloration: belly less spotted vs. belly highly spotted; pectoral fin base with 4 – 5 large blackish brown spots and upper brownish mark vs. entirely brown background with few white spots. Luciogobius grandis is only endemic to mainland Japan and South Korea as a template coastal species. However, Luciogobius huatungensis sp. nov. is completely different, being a subtropical species endemic to Taiwan, mainly in the eastern region. The so-called “ Luciogobius grandis ” mentioned in some previous records in Taiwanese fish guide books may have been misidentified and overlooked for this new species.	en	Chen, I-Shiung, Ren, Yu-Ting, Jiang, Guo-Chen, Wang, Shen-Chih, Chang, Chih-Wei (2024): Three new species of Luciogobius Gill (Teleostei: Gobiidae) from Taiwan.

F74987AEFFA2FFE238C4FC54FBD5BD07.taxon	discussion	Remarks Luciogobius newtaipeiensis sp. nov. is quite similar to Luciogobius guttatus Gill, 1859 due to the similarities in the number of pectoral fin rays and the presence of one upper free ray, more so than any other congeneric species. However, Luciogobius newtaipeiensis sp. nov. can be well distinguished from Luciogobius guttatus by the following features: (1) second dorsal fin rays I / 11 vs. modally I / 12; (2) anal fin rays I / 12 vs. modally I / 13; (3) vertebral count: 16 + 20 = 36 vs. 17 + 21 = 38; (4) an upper dermal projection on orbit: present in male vs. none; and (5) specific coloration: pectoral fin membrane with less brown spotted merely extending around anterior 1 / 3 of fin membrane vs. rather high black spotted extending beyond middle of fin membrane. Since L. guttatus is believed to be an endemic species to Japan, it is possible that some fish guide books in Taiwan may have misidentified this new species as the so-called “ Luciogobius guttatus ”.	en	Chen, I-Shiung, Ren, Yu-Ting, Jiang, Guo-Chen, Wang, Shen-Chih, Chang, Chih-Wei (2024): Three new species of Luciogobius Gill (Teleostei: Gobiidae) from Taiwan.
