Fig. 2. Photographs of whole specimens of species of Limnadopsis. (A) L. birchiv, (B ) L. tatei; (C) L. parvispinus\ (D) L. minuta; (E) L. 
multilineata-, (F) L. occidentalis; (G) L. paradoxa\ ( H) L. pilbarensis. Scale bars 5 mm. 
and only two lobes on the first antennae. Finally, and first 
introduced in the generic key provided by Richter & Timms 
(2005), all species of Limnadopsis have spines on the tip of 
the movable finger of the clasper, not a sucker as in other 
species of Limnadiidae. This unique character, together with 
the large and protruding first spine of the telson spine rows 
can be used to diagnose the genus, with limited reference 
as well to the numerous well-marked growth lines and 
dorsal carinae, The general appearance of specimens of 
Limnadopsis is shown in Figs. 1, 2.
