With a small specimen in hand, I take a close look at the key features of this genus. It is a very close match with N. australiensis … but equally, it may be one of several undescribed, all black species of Australian Nitela.
(specimen #2603A)

A close look at our local Sphodrotes species … now confirmed as Sphodrotes punctuosa, the type species for the genus. In addition to the detailed evidence and logic behind my species ID, I’ve included brief biological observations and a small set of images.

Also included is a summary table for the 12 species of this endemic – and little known – Australian genus.
