This species is widely distributed in the western Pacific Ocean, including Japan ( Nakabo & Doiuchi, 2013 ), East China Sea ( Yamada et al, 2007 ), Taiwan ( Amaoka & Ho, 2019 ), and Vanuatu ( Voronina & Causse, 2014 ).

“…The dextral specimen (NMMB-P 38889) and one sinistral specimen (NMMB-P 38874) were dissected to examine the internal organs. Determination of sex follow Amaoka & Ho (2019) , with specimens possess rostral spine, mandibular knob, and a rather wide interorbital space identified as male, others as female or juvenile.…”

“…The sinistral flatfish family Bothidae, currently comprised of 20 genera and 169 species, are widely distributed in tropical to temperate waters globally ( Amaoka & Ho, 2019 ; Fricke, Eschmeyer & van der Laan, 2023 ). Among them, the genus Parabothus ( Norman, 1931 ) can be discriminated from other bothid genera by having an elliptical body; tip of isthmus below or slightly behind the posterior margin of the eye; scales on ocular side with moderately long ctenii; eyes separated by a concave space; usually absence of rostral spine in males; no white blotches on anterior margin of head ( Amaoka, Mihara & Rivaton, 1997 ; Amaoka & Ho, 2019 ).…”

“…There are currently ten species recognized as valid and distributed in the Indo-West Pacific Ocean ( Voronina, Pruvost & Causse, 2017 ), with four species currently recognized in Taiwanese waters, namely, Parabothus coarctatus ( Gilbert, 1905 ), Parabothus kiensis ( Tanaka, 1918 ), Parabothus polylepis ( Alcock, 1889 ), and Parabothus taiwanensis Amaoka & Shen, 1993 ( Amaoka & Ho, 2019 ). Among these species, P .…”

Background Reversed condition is rarely found in most flatfishes in natural environment, except for some certain species. The mechanism controlling the reversals in flatfishes has been studied in some cultivated species, whereas some have only few cases for the entire family and remain unclear. Here, we report the first record of a dextral (reversed) specimen of Parabothus taiwanensis Amaoka & Shen, 1993 collected off southwestern Taiwan recently. It represents the second reversed case ever recorded in Bothidae. We aim to provide a detailed description of this dextral specimen and compared to the sinistral (normal) specimens collected from the vicinity. Methods Specimens were fixed in 4% formaldehyde and transferred to 70% ethanol for preservation. Meristic and morphometric characters were examined for both dextral and sinistral specimens. Dissections were made on specimens to confirm the position of internal organs. Lastly, X-radiographs were taken to elucidate the osteological features. Results As a result, no differences of both meristic and morphometric characters were observed between the dextral and sinistral specimens. Nevertheless, situs inversus viscerum is discovered in the dextral specimen for the first time in Bothidae and the sixth record within flatfishes.

Specimens of the largescale dwarf flounder, Engyprosopon macrolepis (Regan, 1908) (Pleuronectiformes: Bothidae), were collected from the fishery landing of Chi-kan, Peng-hu Islands, western Taiwan. Although this species has been recorded from western Pacific Ocean including the Philippines and Japan, it has never been recorded from Taiwanese waters. Therefore, our specimens represent the first record for Taiwanese waters and fill a gap in the distribution of this species between the two countries. A detailed description of the specimens, including coloration of the fresh condition is provided and compared to the data of specimens collected in other regions. With the addition of E. macrolepis, a total of 11 species of Engyprosopon are recorded from Taiwanese waters, and we suggest that more species are expected to occur off Taiwan.
