Abstract

Four new species of Gomphodella De Deckker, 1981 are described in the present paper, thereby doubling the number of known recent species. All new species were collected in subterranean waters of the Pilbara region in Western Australia. Gomphodella belongs to the subfamily Timiriaseviinae and the genus is endemic to Australia. In order to facilitate identification of the recent Timiriaseviinae, a key to all species is presented. Only three of the 52 species recognized were not included in the key, due to a lack of distinguishing characters. In addition, Cytheridella chariessa Rome, 1977 is herein synonymized with C. damasi Klie, 1944. Cladistic analysis is also used to show phylogenetic relationships between the species of Gomphodella and the genera of the Timiriaseviinae. The first analysis included eight known Gomphodella species and two outgroup taxa, i.e., representatives of the genus Gomphocythere described from Australia and New Zealand. This analysis was based on 19 morphological characters, and resulted in seven equally parsimonious trees, 36 steps long, with consistency and retention indices of 0.56. The second analysis included all 52 recognized species of Timiriaseviinae and was based on 29 morphological characters. It resulted in 31 equally parsimonious trees with a length of 31 steps, a consistency index of 0.76 and a retention index of 0.94. The majority rule trees are presented herein. As a result of the second analysis, the genus Thaicythere Savatenalinton, Borgonie & Martens, 2008 is synonymized with Metacypris Brady & Robertson, 1870. © 2009 Brill Academic Publishers.
