8E7187A2FFBBFFC1698B5DDF9E88CD11.taxon	etymology	Etymology. The name wolof refers to the ethnic group native to Senegal, Gambia, and in a lesser extent, to Mauritania. Most of the known geographic range of the newly described species overlaps with the Wolof ethnic distribution. The name is a noun in genitive case.	en	Sainz-Escudero, Lucía, Alonso, Miguel, Sánchez-Vialas, Alberto (2022): Diversity and distribution of Anostraca in temporary ponds in Western Africa with description of a new species of Streptocephalus Baird, 1852 (Pancrustacea: Branchiopoda: Streptocephalidae).

Streptocephalus wolof is known from the following localities in Senegal: 2 km north of Podor, Diembéreng, 1.9 km south-east of Bokiladji, 6 km east of Koutenable and Diabal (Table 2). Future studies could likely extend its distribution to the neighboring countries Mauritania, Gambia, Mali, Guinea, and Guinea-Bissau. The previous recorded populations identified as S. zeltneri in Senegal [Lingure and Palagu (Monod 1969; Hamer et al. 1994 b; Maeda-Martínez et al. 1995 b)] require revision as they were not examined by us, and therefore, we were unable to confirm its taxonomic identity. However, we tentatively treated these records as S. zeltneri until additional studies confirm its identity (Fig. 1).	en	Sainz-Escudero, Lucía, Alonso, Miguel, Sánchez-Vialas, Alberto (2022): Diversity and distribution of Anostraca in temporary ponds in Western Africa with description of a new species of Streptocephalus Baird, 1852 (Pancrustacea: Branchiopoda: Streptocephalidae).

8E7187A2FFBBFFC1698B5DDF9E88CD11.taxon	discussion	Remarks. The new species is closely related to Streptocephalus zeltneri. Both species cannot be distinguished based on adult morphological characters, and consequently they can be considered as cryptic species (Marrone et al. 2017). However, they differ on the basis of the eggs macrosculpture. Eggs of S. wolof present their surface covered with carinated ribs, delimiting polygons of variable number of sides (Fig. 3 A). This trait was consistent in each revised population that contained mature females. Streptocephalus wolof is the most commonly found and widespread Anostraca species in Senegal, occurring in several ecoregions (including the Sahelian and Sudanian savannas, and the Guinean forest savanna close to the Guinean forest) (Fig. 1). The studied specimens of S. wolof were found during the rainy season in temporary ponds, both with transparent and turbid waters, often in syntopy with amphibian larvae, as Sclerophrys xeros (Tandy, Tandy, Keith & Duff-MacKay, 1976), Kassina senegalensis (Duméril & Bibron, 1841), K. fusca Schiøtz, 1967, Ptychadena bibroni (Hallowell, 1845), and Phrynobatrachus francisci Boulenger, 1912 (Fig. 5).	en	Sainz-Escudero, Lucía, Alonso, Miguel, Sánchez-Vialas, Alberto (2022): Diversity and distribution of Anostraca in temporary ponds in Western Africa with description of a new species of Streptocephalus Baird, 1852 (Pancrustacea: Branchiopoda: Streptocephalidae).

Senegal: pool at Ndilla dam, close to Linguère (Monod 1969; Hamer et al. 1994 b); Palagu (Maeda-Martínez et al. 1995 b). Geographic distribution. This species is only known from Mali and Senegal (Monod 1969; Hamer et al. 1994 b; Maeda-Martínez et al. 1995 b; Belk & Brtek 1997). Records from Sudan (Hamer et al. 1994 b; MaedaMartínez et al. 1995 b) are currently located in Mali. The previously recorded populations of S. zeltneri in Senegal need revision (see comments on the geographic distribution account of S. wolof).	en	Sainz-Escudero, Lucía, Alonso, Miguel, Sánchez-Vialas, Alberto (2022): Diversity and distribution of Anostraca in temporary ponds in Western Africa with description of a new species of Streptocephalus Baird, 1852 (Pancrustacea: Branchiopoda: Streptocephalidae).

8E7187A2FFA2FFDC698B5CEB9DEACE89.taxon	discussion	Remarks. According to the literature, Streptocephalus zeltneri is morphologically similar to S. trifidus Hartland-Rowe, 1969 and S. bouvieri Daday 1910 (Daday 1910 a; Hartland-Rowe 1969; Hamer et al. 1994 b). In their revision, Maeda-Martínez et al. (1995 b) included S. zeltneri in a species group formed by S. bouvieri, S. gauthieri, S. rothschildi and S. spinifer. A more detailed study including morphological and molecular characters would be desirable to unveil the evolutionary relationships among the species of the bouvieri species group sensu Maeda-Martínez et al. (1995 b). Brendonck & Coomans (1994) provided a description and a picture of the eggs of the holotype of S. zeltneri, stating that the eggs have simple and more or less regular polygons, and that their ribs are unkeeled. Similarly, the eggs from our samples of S. zeltneri of southeastern Senegal, have unkeeled ribs (Fig. 3 B). This trait was consistent in the revised populations of S. zeltneri with mature females (two out of the three populations). Specimens were found in small and transparent pools with clam shrimps. Live specimens present the cercopods and the brood pouch with a strong red coloration.	en	Sainz-Escudero, Lucía, Alonso, Miguel, Sánchez-Vialas, Alberto (2022): Diversity and distribution of Anostraca in temporary ponds in Western Africa with description of a new species of Streptocephalus Baird, 1852 (Pancrustacea: Branchiopoda: Streptocephalidae).

(1992) noted the singularities of Streptocephalus sudanicus based on the presence of spinules on the finger dorsal side and the existence of tetrahedral eggs (Fig. 3 C). They also created a new taxon, the subgenus Parastreptocephalus, based on these characters. Other species included in this taxon are S. lamellifer Thiele, 1900, S. kaokoensis Barnard, 1929, and S. zuluensis Brendonck & Hamer, 1992 (Brendock et al. 1992). The studied pecimens of S. sudanicus were found in pools with turbid water.
