Recordsofthe WesternAustralianMuseum 23: 193-198 (2006). A troglobitic cryptopid centipede (Chilopoda: Scolopendromorpha) from western Queensland GregoryD. Edgecombe AustralianMuseum,6CollegeStreet,Sydney, NSW2010,Australia Abstract - Cryptops Trigonocryptops camoowealensis sp. nov. from Five ( ) O'Clock cave in the Camooweal district of Queensland, is the second troglobitic species of the subgenus Trigonocryptops to be described from Australia. Thenew species is less troglomorphic than is a recently described congenerfromcavesintheNullarborRegionofWesternAustralia. INTRODUCTION SYSTEMATICS The scolopendromorph Cryptops Leach, 1815, is FamilyCryptopidaeKohlrausch,1881 one of the most diverse centipede genera, with 153 named species (Lewis 2002). Among these, SubfamilyCryptopinaeKohlrausch, 1881 troglomorphic species include members of the subgenera Cryptops Leach, 1815, and Genus CryptopsLeach,1815 Trigonocryptops Verhoeff, 1906 (see Edgecombe 2005 and Lewis 2005 for discussion of subgenera of Typespecies Cryptops and diagnostic characters of Scolopendra hortensis Donovan, 1810, by Trigonocryptops). Troglomorphic species of monotypy. Cr\rptopshavebeendescribedfromcavesinEurope, the Canary Islands, Cuba, and Western Australia. The latter record is based on the highly troglomorphic C. (Trigt>nocryptops) roeplainsensis Edgecombe, 2005, which occurs in caves in the Nullarbor Region. This troglomorph was the first Australian species to be referred to C. (Trigonocryptops), which is otherwise known from Spain, North Africa, tropical West, Central and East Africa,Peru,Brazil,Cuba,India, Indonesia,and New Caledonia. Additional records of C. ('Trigonocryptops)inAustralia,aswellasoccurrence in New Zealand, Fiji and theSolomon Islands, were \CAIRNS provided bythereassignmentofC. spinipesPocock, 1891,tothatsubgenus(Edgecombe2005).

The Camooweal caves are part of the extensive Barkley Karst Region, developed in the Cambrian Camooweal Dolomite. Five O'Clock cave (C-36 of Matthews 1985) has a length of 800 m +/- 10 m, and is dry with connectionstointermittentstandingwater.
