Studies of Australian Hydrobiosella Tillyard: a review of the Australian species of the Hydrobiosella bispina Kimmins group (Trichoptera: Philopotamidae)

Abstract

Descriptions and keys are provided for males of 12 philopotamid caddis fly species in the genus Hydrobiosella Tillyard, H. bispina group. Among these are ten new species from Australia: Hydrobiosella bilga, H. dugarang, H. gurara, H. moorda, H. mundagurra, H. nandawar, H. thurawal, H. unispina, H. woonoongoora and H. yokunna. Females of six of the species are also described. Group separation is based on male genitalic characteristics, the key features for the H. bispina group being inferior appendages with an elongate terminal segment, fringed ventrally by a row of dark setae, and nearly all species with paired, hooked lateral processes on segment ten. Of the 12 species treated here, all are endemic to the east coast region of the Australian mainland.

Two further species groups and new species among Australian Hydrobiosella Tillyard: new species from south-eastern Australia (Trichoptera: Philopotamidae)

“…He diagnosed three groups based primarily on male genitalia and these, the H. bispina, H. eminentia and H. waddama species groups were detailed more recently and included in an updated key to the Australian species and species group (Cartwright 2010(Cartwright , 2012a(Cartwright , 2012b. Two further species groups are diagnosed here and include 11 newly described species which bring to 54 the total number of Australian species of Hydrobiosella.…”

“…The recent history of the genus Hydrobiosella Tillyard in Australia is revised and summarized by Cartwright (2010Cartwright ( , 2012aCartwright ( , 2012b. In brief, the first Australian species in the genus were described in 1953 by Mosely (in Mosely and Kimmins, 1953).…”

“…In brief, the first Australian species in the genus were described in 1953 by Mosely (in Mosely and Kimmins, 1953). Further species were added by Korboot (1964); Jacquemart (1965); (Neboiss, 1977(Neboiss, , 1982(Neboiss, , 2003 and Cartwright (2010Cartwright ( , 2012aCartwright ( , 2012b. A total of 53 species of Hydrobiosella are known worldwide: from Australia (43 species -Cartwright 2012b), New Zealand (4 species -Morse 1999) and New Caledonia (6 species - Espeland and Johannson 2007).…”

“…Two further species groups are diagnosed here and include 11 newly described species which bring to 54 the total number of Australian species of Hydrobiosella. Australian mainland species in the H. waddama group have recently been reviewed (Cartwright 2012b).…”
