Legs: CI yellow; trochanter I yellow with dark brown apical rim; coxae and trochanters II and III yellowish with brown areas, and covered with grey pruinosity; FI and TI yellow; It 1 distinctly brown, in contrast to yellow TI and distal tarsomeres; It 2–5 yellow; It 2 and It 3 each with two closely appressed subapical pv setae, which are distinctly longer than single corresponding single av seta.(MSSC); It 2–5 ventrally flattened with pale vestiture; FII and TII yellow; It 1–2 brown, and It 3–5 yellow; FIII yellow basally, grading to brown in distal third; TIII yellow with but distal quarter brown; IIIt dark brown.

Remarks. Bandella cerra is known from Nothofagus moorei dominated cool temperate rainforest in the Barrington Tops and Mt Banda Banda, in northeastern New South Wales. These sites are in the Central Eastern Rainforest Reserves of Australia (CERRA) World Heritage Area, hence the specific epithet.
