LLUÍS DEL CERRO AND DOMÉNEC LLORIS Instiiut de Ciéncíes del Mar (C.S.l.c.), Passeig lQan de Borbó, sin 08039, Barcelona, Spain. ABSTRACT , . A new species of the family Triglidae, Lepidorrigla russelli sp. nov. , from the waters off the Northem Territory and Queensland (Au'stralia) ii presented. The new laxon is compared with its similar relatives in !he genus LepidotTigla Günther, 1860: L. faurei Gilchrist and Thompson, 1914, and L. cadmani Regan, 1915. Brief comments on the genus Lepidorrigla are included. KEYWORDS: Triglidae, Lepidorrigla russelli, sp. nov., taxonomy, new species, F.A.O. Fishing Area 71 , northem Australia, eastem Australia. INTRODUCTION Measurements and counts of body parts are a combination of methods of Hubbs and Lagler As part of a general study on ¡he systematics (1958), Teague (1951), Richards (1968), and of supra-specific taxa of the family Triglidae, a Richards and Saksena (1977), with the excep­ large number of specimens collected in different lion of the following characters. The length of parts of¡he world have been examined.
