Systematics and ecology of Linderiella baetica n. sp. (Crustacea, Branchiopoda, Anostraca, Chirocephalidae), a new species from southern Spain

摘要

Linderiella baetica n. sp. (Anostraca, Chirocephalidae), is described from atemperate Mediterranean climate, episodic temporary fresh water body inPuerto Real (Cadiz, South Spain). Linderiella baetica n. sp. is characterizedby the display of the shape of the basomedial outgrowth on the male secondantenna, margin structure of praepipods, structure of medial margin of endopod,penis basal projections, horn-like process on the inner side of the femaleantenna, female genital somites and of a combination of morphological featuresinvolving egg morphology. The study includes a morphological analysis usingoptical and scanning electron microscopes. Based on the differential diagnosis,a dichotomous key for males, females and resting eggs to Linderiella species isproposed. The diagnosis is complemented with phenology of the species andaccompanying fauna and aquatic vegetation, and physico-chemical evolutionof water along monitoring.
