07331834FF83FF9CFF18D28EEEDDF842.taxon	description	Australoheros mboapari can be distinguished from all other species of Australoheros by absence of scales from all or lower half of cheek, or present deeply embedded (vs exposed in thin skin layer or with free margins and covering cheek). Australoheros mbapoari shares with A. forquilha, A. ricani, A. tembe, and A. ykeregua a row of minute scales along base of dorsal fin reaching anteriorly to or almost to anterior insertion of dorsal fin (vs scale layer ending at middle or more posterior position along dorsal-fin base); with A. ricani black soft dorsal fin in adult females (vs soft dorsal fin light). Australoheros mboapari differs from all other species of Australoheros except for A. forquilha, A. tembe, and A. ykeregua by absence of abbreviated dorsal portions of bars 5 – 6 anterodorsally on flank; prepelvic scales deeply embedded (vs with free margins); caudal fin subtruncate (vs rounded); broad pelvic-fin tip with first and second rays subequal in length (vs first ray longest) (first may be longer also in A. ykeregua); from all except for A. forquilha, A. kaaygua, A. tembe, and A. ykeregua by deep lachrymal bone).	en	Santos De Lucena, Carlos A., Kullander, Sven, Norén, Michael, Calegari, Bárbara Borges (2023): Healing nomenclature: making the names Australoheros mboapari and Australoheros ricani available (Teleostei: Cichlidae).

07331834FF80FF9FFF18D0E0EE9EF819.taxon	discussion	Definition. Based on observation of the morphology of adults in the type series, the position in the phylogenetic trees based on mt-cyb and mt-coI, and more than 3 % divergence in minimum uncorrected p - distance from other species of Australoheros (Lucena et al. 2022), A. ricani is a distinct evolutionary lineage. No morphological autapomorphy is registered. Specimens of A. ricani share with A. mboapari, A. forquilha, and A. ykeregua a row of minute scales along the dorsal-fin base extending cephalad to close to anterior insertion of dorsal fin (fourth dorsal-fin spine), and with A. mboapari a black soft dorsal fin in females (vs dorsal fin black throughout, or with black blotches at intervals). It is distinguished from A. mboapari by 3 – 5 rows of scales on cheek, exposed or discernible beneath skin cover.	en	Santos De Lucena, Carlos A., Kullander, Sven, Norén, Michael, Calegari, Bárbara Borges (2023): Healing nomenclature: making the names Australoheros mboapari and Australoheros ricani available (Teleostei: Cichlidae).

07331834FF80FF9FFF18D0E0EE9EF819.taxon	etymology	Explanation of specific name. Oldřich Říčan, University of South Bohemia, was the first to recognise Australoheros species richness, and made the pioneering analyses, discovering and highlighting the phylogeny and species richness of inland species of Australoheros. The specific name is a noun in the genitive case.	en	Santos De Lucena, Carlos A., Kullander, Sven, Norén, Michael, Calegari, Bárbara Borges (2023): Healing nomenclature: making the names Australoheros mboapari and Australoheros ricani available (Teleostei: Cichlidae).

07331834FF80FF9FFF18D0E0EE9EF819.taxon	discussion	Comparative data for Australoheros mboapari and Australoheros ricani. In the Rio Jacuí drainage, Australoheros mboapari is most similar to the geographically adjacent A. ricani, e. g., in the long row of minute scales along the dorsal-fin base, and absent or indistinct caudal spot. The rare number of five anal-fin spines is recorded from both species. Nonparametric comparison of counts showed that they are distinct (Mann-Whitney U test, p = 0.000 – 0.001) in overlapping number of anal-fin spines (modally five in A. ricani, six in A. mboapari), dorsal-fin spines (modally 15 in A. ricani, 16 in A. mboapari), E 1 scales, upper and lower lateral line scales, but not in number of soft dorsal- and anal-fin rays, or pectoral-fin rays (Lucena et al. 2022). Australoheros mboapari has the highest number of E 1 scales recorded in the genus, modally 26, occasionally 27. Twenty-six E 1 scales are frequent also in A. forquilha and A. ricani. Australoheros mboapari differs from A. ricani in slopes on SL of preorbital depth, lower jaw length, head width, pectoral-fin length, and length of last dorsal-fin spine (ANOVA p <0.05), and on intercept on head length, snout length, orbital diameter, interorbital width, and upper jaw length (ANCOVA, p <0.05) (Lucena et al. 2022). The slight difference in jaw lengths shows in the proportional measurements, (Lucena et al. 2022: figs 13 – 16, where the size ranges are reasonably comparable), A. mboapari has slightly shorter upper jaw (8.8 – 10.9 % SL (vs 10.2 – 11.5 in A. ricani), and lower jaw (11.7 – 14.2 % SL vs 13.1 – 15.7 % in A. ricani). Australoheros mboapari has deeper preorbital than the other coastal Australoheros except for A. acaroides (Lucena et al. 2022: tables 3 – 16). This character, however, is positively allometric, and only extremely large specimens of A. acaroides have a deep lachrymal bone (Lucena et al. 2022).	en	Santos De Lucena, Carlos A., Kullander, Sven, Norén, Michael, Calegari, Bárbara Borges (2023): Healing nomenclature: making the names Australoheros mboapari and Australoheros ricani available (Teleostei: Cichlidae).
