Ilyocryptus paranaensis subsp. inarmatus Kotov, Eliaz-Gutierrez & Gutierrez-Aguirre 2001

Description

Ilyocryptus paranaensis inarmatus Kotov, Eliáz-Gutiérrez & Gutiérrez-Aguirre, 2001

Ovoid body, dorsal keel present but not developed, molting complete; each valve bears a horn-like projection; depression between head and rest of body well developed; setae on the posterior margin of valves with inflated base and armed with a single spine which is followed by setulae; posteriormost setae on the valves armed with setulae. Head triangular shaped, fornices prominent; first segment of antennules with developed mounds; spine on the second segment of endopodite of antenna bi-segmented. Postabdomen wide, preanal part slightly longer than postanal; marginal denticles of the preanal part with regular morphology; 7-9 marginal spines; distalmost part of the postanal part with 7-13 rudimentary lateral setae, up six long lateral setae which are markedly longer than marginal spines; basal spines on the postabdominal claw of different length.

Comments: Ilyocryptus paranaensis inarmatus was initially described from materials obtained in different parts of Mexico. It is likely that this taxon possesses a broad distribution in the Neotropics, even though there is only one known record (in central Brazil) obtained from outside its type-region (Fig. 3B). For further information regarding the morphology of this species regarding the Brazilian population, or information concerning its habitat, see Sousa & Elmoor-Loureiro (2011).
