 Diagnosis.- Axillary pore present, large; mandibu-
 lar teeth 28-51; body lacking large spots; fin spines brown
 to black; 7-8 pectoral-fin rays; black triangles present
 on bases of all rayed fins; eye 31.2-50.2% snout length;
 premaxillary toothpad uninterrupted; secondary branches
 on medial mandibular barbel absent; occipito-nuchal
 shield not covered with skin; granular papillae present
 on skin of body; humeral process length 253.8-437.2%
 of humeral process width; hindgut chamber absent;
 maximum TL 270 mm.
 Synodontis granulosus can be distinguished from
 S. ilebrevis, S. irsacae, S. lucipinnis, S. melanostictus,
 and S. polli by the presence of an axillary pore.
 Synodontis granulosus is further distinguished from
 these species, and also from S. dhonti and S.
 tanganaicae by the lack of secondary branches on the
 medial mandibular barbel (vs. present). An uninterrupted
 premaxillary toothpad further separates S. granulsosus
 from S. ilebrevis, S. irsacae, S. lucipinnis, S.
 melanostictus, S. petricola, S. polli, and S.
 tanganaicae. Synodontis granulosus further differs
 from S. tanganaicae by differences in humeral pro-
 cess shape humerall process length 253.8-437.2% of
 humeral process width in S. granulosus vs. 172.9-
