41. Aphaniops kruppi (Freyhof, Weissenbacher & Geiger, 2017) ―Omani Killifish, Omani Tooth-carp ―Endemic Taxonomy. Original description: Aphanius kruppi Freyhof, Weissenbacher & Geiger, 2017:561, figs. 2-5 [from a spring in Al Mudayrib, Oman, 22°36’46”N, 58°40’31”E; Holotype: ZFMK-ICH 103668]. Status in the Arabian Peninsula. Recorded from Oman in original description by Freyhof et al. (2017); confirmed by Freyhof et al. (2020) from from Oman, and Yemen, and by Esmaeili et al. (2022), and Zarei et al. (2023) from Oman. General distribution. Middle East: Oman and eastern Yemen. Habitat: freshwater. Distribution in the Arabian Peninsula. Widely distributed in Wadis and Aflaj in Oman, and in eastern Yemen. See Freyhof et al. (2020), Esmaeili et al. (2022), and Zarei et al. (2023). Economic importance. No commercial importance. It has potential to be used as aquarium fish. Conservation. Least Concern (LC). Remarks: Several populations of this tooth-carp were reported from Oman by Esmaeili et al. (2022), and Zarei et al. (2023). The synonymy of A. hormuzensis from southern Iran with A. kruppi was proposed by Jouladeh-Roudbar et al. 2020). Howevere, the taxonomic distinctness of A. hormuzensis as a valid taxon was demonstrated by Teimori et al. (2022). According to Teimori et al. (2022) both Bayesian and Maximum likelihood phylogenetic analyses of COI sequences revealed that both A. hormuzensis and A. kruppi are monophyletic, with high support values.
