[[ Pseudolaguvia tuberculata ]]

Britz & Ferraris (2003) diagnose P. tuberculata from P. tenebricosa by the contact between the adipose fin and the base of the last dorsal-fin ray in the former species (while P. tenebricosa and all other congeners lack this contact). I have obtained fresh material from northern Myanmar ( UMMZ 245493) that, except for the adipose fin not contacting the base of the last dorsal-fin ray, is otherwise identical in other respects to P. tuberculata . In some of this material, particularly in smaller specimens, the adipose fin extends anteriorly into a faint ridge that approaches very close to, but never touches, the base of the last dorsal-fin ray. This is most likely the reason behind Prashad and Mukerji's (1929) assertion that the adipose fin contacts the base of the last dorsal-fin ray in P. tuberculata . The adipose-fin base and snout are longer in the material from northern Myanmar than in the paratypes of P. tenebricosa examined (16.8-22.7% SL vs. 14.2-16.0 and 52.7-55.5% HL vs. 48.1-50.0 respectively), and it is these reasons that argue for the continued recognition of the two species as distinct. An examination of the two specimens from northern Myanmar ( CAS 98614) quoted by Britz & Ferraris (2003) shows that they are conspecific with my material ( UMMZ 245493). They are hence reidentified here as P. tuberculata .
