Leydigia (Neoleydigia) cf. striata Birabén, 1939 (Crustacea: Cladocera: Chydoridae) from Colombia and its differentiation from L. (N.) cf. ipojucae (Brehm, 1938)

Abstract

-This paper concerns the chydorid cladoceran Leydigia

Cladocera (Crustacea, Branchiopoda) of a temporary shallow pond from northern Colombia

“…striata Birabén, 1939 Material examined: fifty adult females, 5 adult males catalog number:CBUMAG: MEI: 0027, CBUMAG:MEI:0029-1,CBUMAG:MEI:0029-2 Remarks: It was found among macrophytes in all samplings and was the most abundant observed species among the family Chydoridae. The morphology of the fifty adult female specimens from La Guajira, Colombia agrees in general with previous descriptions and illustrations of the species (Kotov et al 2003, Kotov & Elías-Gutierrez 2004, Kotov 2009, Fuentes-Reinés 2014b, Fuentes-Reinés & Elmoor-Loureiro 2015a. Leydigia cf striata can be recognized from its congeners by a unique combination of characters including: (1) The female postabdomen is the narrowest among its congeners of acanthocercoidesgroup; (2) setules in lateral fascicules on labrum are shorter or the same size as marginal setae; (3) preanal margin of female postabdomen with hillokcs, (4) basal segment of the distal most scrapper of Limb II (setulated).…”

“…In Colombia, the knowledge about the cladoceran fauna has been increased in recent years considerably (Fuentes-Reinés & Elmoor-Loureiro 2015a, Fuentes-Reinés et al 2012, Fuentes-Reinés & Zoppi de Roa 2013, Fuentes-Reinés 2014a, 2014b, 2014c, 2015, Kotov & Fuentes-Reinés 2014, Sinev & Fuentes-Reinés 2016, Fuentes-Reinés et al 2018. According to Fuentes-Reinés et al (2018), there are 107 valid species in Colombia, being the Caribbean region the one with the largest number of recorded species (72 spp.…”
