Branchinecta oterosanvicentei n. sp. (Branchiopoda: Anostraca), a new fairy shrimp from the Chihuahuan desert, with a proposal for the conservation of the Branchinectidae of Mexico

Reproductive cycle and genitalia of the fairy shrimp Branchinella thailandensis (Branchiopoda: Anostraca)

“…Structural morphology of cross-sectioned egg shells has been studied in species of several genera (Gilchrist, 1978;De Walsche et al, 1991;Maeda-Martínez et al, 1992;Hill and Shepard, 1997). For species of Branchinecta, Obregón- Barboza et al (2002) report three types of shells: 1) shells with a subcortical space present, the outer cortex and inner alveolar layer completely separated from each other; 2) shells with a subcortical space present, but the outer cortex and inner alveolar layer are not completely separated from each other; and 3) shells with a subcortical space absent and composed of a single spongy cortex. Branchinella thailandensis belongs to the fairy shrimp group without a sub-cortical space beneath the egg shell.…”

Eubranchipus stegosus n. sp. (Crustacea: Anostraca), a bizarre new species of fairy shrimp from the southeastern United States

“…In fact only western and southern North America have been extensively surveyed (e.g., Dodds, 1915;Mackin, 1938;Prophet, 1963;Belk, 1975Belk, , 1992Eng et al, 1990;Maeda-Martı´-nez, 1991;Hill et al, 1997;Maeda-Martı´nez et al, 1997a,b;Eriksen & Belk, 1999;Rogers, 2001;Rogers et al, unpublished). Even in these areas, new species and new records are being found with regularity (e.g., Belk & Fugate, 2000;Rogers 2000Rogers , 2001Rogers & Fugate 2001;Belk & Rogers, 2002;Obrego´n-Barboza et al, 2002;Maeda-Martı´nez et al, unpublished;Rogers & Quinney, unpublished).…”

“…Since the vast majority of species rely solely upon seasonal wetlands, large branchiopods have become flagship animals for ephemeral wetland habitat imperilment and are the subject of increasing conservation attention (USFWS, 1994;Eriksen & Belk, 1999;Obrego´n-Barboza et al, 2002;Rogers, 2002a,b;Rogers et al, unpublished).…”
