Treatment

Key to Erenna View in CoL species based on their nectophores.

- No "horn" canals. Thrust block with median indentation...................................................... 2

2 Mature nectophores with digitate processes on thrust block.................................................... 3

- Mature nectophores without digitate processes on thrust block................................................. 4

3 Upper lateral ridges divide close to ostium. Incomplete lateral ridges present............... Erenna richardi Bedot, 1904 View in CoL

- Upper lateral ridges undivided. No lateral ridges........................................... Erenna sirena View in CoL sp. nov.

4 Upper lateral ridges divide close to ostium forming broad "m"-shaped branches. Thrust block consisting of one pair of lobes............................................................................... Erenna laciniata Pugh, 2001 View in CoL

- Upper lateral ridges undivided. Thrust block with two pairs of lobes........................ Erenna insidiator View in CoL sp. nov.
