A review of the Australian species of Ecnomina Kimmins and Daternomina Neboiss (Trichoptera: Ecnomidae)

Abstract

Descriptions, keys and a checklist are provided for males of 52 ecnomid caddisfly species, including 35 species new from Australia. These are placed in two genera, Ecnomina s. str. Kimmins and Daternomina Neboiss. Females of 31 species are also described. The new species are: Daternomina alicewellsae, D. bifida, D. birrarung, D. genoaensis, D. hamata, D. ikathan, D. loowa, D. scissura, D. ulltra, D. warrook, Ecnomina alluna, E. anulla, E. attunga, E. beela, E. boogoo, E. bula, E. concava, E. foramen, E. gippslandica, E. gullea, E. incisura, E. kepin, E. lamingtonensis, E. manicula, E. merki, E. ramosa, E. rostrata, E. scutica, E. serrata, E. sheldoni, E. specensis, E. volcella, E. wamoom, E. wanarra, and E. wirromandi. New combinations are suggested for Daternomina trulla (Neboiss, 1982), D. merga (Neboiss, 1982), D. scindens (Neboiss, 1982). Generic separation is based on female genitalic features supported by small differences in wing, head warts and male genitalic characteristics. Of the two genera treated here, Daternomina is endemic to Australia; one species of Ecnomina has been recorded from each of New Zealand and New Caledonia.
