Etymology. The species name is from the Latin word for a knob, referring to the irregular spine on the palm of gnathopod 1.

Diagnostic description. Antenna 1 callynophore absent. Eyes present. Mouthpart bundle subconical. Mandible left incisor with straight margin, smooth, right with slightly convex margin, smooth; lacinia mobilis absent; molar absent; palp attached proximally, article 2 longer than article 3. Maxilla 1 outer plate with 7 setal teeth in a 6/1 crown arrangement, outer row with cusps in 1 row; palp apical margin not serrate, without apical setae. Maxilliped palp 3-articulate. Gnathopod 1 subchelate; ischium short; carpus posterior margin produced into broad triangular lobe; propodus subquadrate, proximal margin transverse, palm serrate, posterodistal corner produced into blunt, distally expanded spine, without robust setae. Gnathopod 2 minutely chelate; carpus much longer than propodus (about 2x); palm obtuse. Pereopod 4 coxa posteroproximal excavation small. Pereopods 5–7 basis with strongly serrate posterior margin; dactylus short, slender. Epimeron 3 posterior margin smooth, posteroventral corner acute. Uropod 3 peduncle subequal to outer ramus, with large distoventral spur; inner ramus vestigial; outer ramus 2-articulate; rami without robust setae, without plumose setae. Telson about as long as broad, entire, distally tapered, without dorsal robust setae.

Male not known.

Remarks. Podoprionella bulla is very similar to P. dagadugaban but differs in having no callynophore on antenna 1, only one set of cusps on the setal teeth of maxilla 1 outer plate, an irregular blunt spine on the posterodistal corner of gnathopod 1 propodus, no serrations on the inner margin of gnathopod 1 dactylus and a much deeper posterior lobe on the coxa of pereopods 5 and 6. Both species differ from the northern hemisphere P. fissicaudata and P. norvegica in having only two robust setae in the mandible accessory setal row, a transverse serrate palm on gnathopod 1 and a vestigial inner ramus on uropod 3.

Distribution. South-eastern Australia; 363 m depth.
