Diagnosis: Tatia is diagnosed by 13 molecular and three morphological synapomorphies. Non-exclusive: (1) coronomeckelian bone obliquely positioned (char. 3596: 0 → 1), reversed in Tatia intermedia and Tatia sp. 4 , convergent in Duringlanis romani , Balroglanis macracanthus , Gelanoglanis and Liosomadoras ; (2) hyomandibula and metapterygoid separated from each other (char. 3620: 0 → 1), convergent in Ageneiosini , Gelanoglanis and Centromochlus ; and (3) contralateral anteromedial processes of basipterygium sutured to each other on anterior portion only (char. 3723: 0 → 2), reversed in Tatia musaica and Tatia meesi , convergent in Gelanoglanis , Centromochlus , Entomocorus , Gephyromochlus , Trachelyopterichthys , Trachelyopterus albicrux , Trachelyopterus insignis , Trachelyopterus striatulus and Trachelyopterus teaguei .

C o m p a r i s o n s: Ta t i a d i f f e r s f r o m r e m a i n i n g centromochlines, exceptGelanoglanis and Centromochlus , by having the hyomandibula and metapterygoid separated from each other (vs. hyomandibula and metapterygoid contacting each other). Tatia (but not Tatia intermedia and Tatia simplex ) is distinguished from Glanidium , except Glanidium cesarpintoi , Balroglanis , Ferrarissoaresia and Centromochlus , by the lack of serration on the posterior border of the dorsal-fin spine (vs. dorsal-fin spine serrated on posterior border). It differs from Duringlanis and Centromochlus by having the outer mental barbel longer than inner (vs. outer and inner mental barbels of approximately the same length); from Centromochlus and Balroglanis by having the maxillary barbel laterally positioned, not visible ventrally (vs. proximal portion of maxillary barbel ventrally positioned, in such a way that it is visible ventrally), and eye not visible, or little visible in ventral view (vs. eye ventrally displaced, in such a way that almost the entire eye is visible in ventral view); and from Gelanoglanis by the rounded and depressed head (vs. laterally compressed head) and mouth straight (vs. mouth sinuous in lateral view). Tatia , except Tatia meesi , Tatia musaica , Tatia reticulata and Tatia simplex , is further distinguished from Gephyromochlus , Ferrarissoaresia , Balroglanis and Gelanoglanis by the possession of an anterior nuchal plate (vs. anterior nuchal plate absent).

SUBFAMILY AUCHENIPTERINAE BLEEKER, 1862 (CLADE 67)

Auchenipterini Bleeker, 1862 (in Bleeker, 1862 –63): 14 (type genus: Auchenipterus Valenciennes, 1840 View in CoL ).

I n c l u d e d t r i b e s: A s t e r o p h y s i n i, A g e n e i o s i n i, Auchenipterini , LiosomadoradiniandTrachelyopterini.

Diagnosis: Auchenipterinae are diagnosed by 21 molecular and three morphological synapomorphies. Exclusive: (1) lateral margin of frontal not participating in orbital margin (char. 3553: 0 → 1), reversed in Entomocorus , Tocantinsia , Trachycorystes trachycorystes and Trachelyichthys . Non-exclusive: (2) coronoid process of anguloarticular developed as a large and laminarprocess (char.3602:0→1),reversedin Ageneiosus (except Ageneiosus dentatus ), Auchenipterichthys , Pseudauchenipterus and Trachelyichthys , convergent in Tatia boemia , Tatia nigra , Tatia jacaratia , Tatia sp. 4 , Glanidium and Ferrarissoaresia ; and (3) compound centrum including up to sixth vertebra (char. 3667: 1 → 2), reversed in Auchenipterini and Trachelyopterini (except Pseudepapterus ), Tympanopleura cryptica , Tympanopleura brevis and Ageneiosus militaris , convergent in Glanidium catharinensis and Glanidium cesarpintoi .

Comparisons: Auchenipterinae is mostly represented by members of large body size, except Epapterus , Pseudepapterus and Spinipterus , and differs from all centromochlines by having a medium to long anal fin (vs. short anal fin), genital tube of adult males attached to the base of the anal-fin origin and united by skin to the anal-fin rays (vs. genital tube of adult males located anterior to the anal-fin rays and apart from anal-fin base), lack of sexual dimorphism in the shape of the anal fin (vs. secondary sexual dimorphism present in the anal fin, where the male and female have distinct anal-fin shapes), and by the genital papilla of adult males not being covered by a hood-like flap of skin (vs. adult males with a hood-like flap of skin covering the urogenital base, except Gelanoglanis ).
