Two parthenogenetic females from Bonita pond (15 ° 35 ' 22.1 " S, 47 ° 41 ' 50.1 ”W), Ecological Station of Águas Emendadas, Planaltina, Distrito Federal, Brazil, collected by GEEA on 27.05. 2008. Fourteen parthenogenetic females and one ephippial female from Henrique pond (15 ° 41 ' 16.5 "S, 47 ° 56 ' 22.2 "W), Brasília National Park, Distrito Federal, Brazil, collected by LMAEL (EL00723, EL01716) and GEEA.

Goiás. Two parthenogenetic females from Capivaras pond (18 ° 16.245 'S, 52 ° 50.529 'W), Emas National Park, Mineiros, Goiás, Brazil, collected by Guilherme Miranda on 0 9.12. 2000, (EL00728). Two parthenogenetic females from Feia Pond (15 ° 34 ' 25.05 "S, 47 ° 18 '9.00"W), Instruction Field of the Brazilian Army, Formosa, Goiás, Brazil, collected by LMAEL on 12.12. 2009 (EL02511). Thirty parthenogenetic females from Cabloca II pond (15 º 48 ' 22.6 ''S, 47 º 14 ' 10.6 ''W), Instruction Field of the Brazilian Army, Formosa, Goiás, Brazil, collected by GEEA on December/ 2009. Two parthenogenetic females from Estiva stream (14 °06'40,3"S, 47 ° 44 '02,2"W), Chapada dos Veadeiros National Park, Alto Paraíso, Goiás, Brazil, collected by GEEA on 13.03. 2013, (EL02377). One parthenogenetic female from a pond at Chapada dos Veadeiros National Park (14 °04'26,5"S, 47 ° 39 '40,7"W), Alto Paraíso, Goiás, Brazil, collected by GEEA on 14.03. 2013 (EL 2512).

Ceará. One parthenogenetic female from a lagoon at Pecém (3 ° 33 ’ 22 ”S, 38 ° 49 ’ 26 ”W), São Gonçalo do Amarante, Ceará, Brazil, collected by Maria Beatriz Gomez e Souza on 18.12. 2007.

FIGUR 2. Anthalona brandorffi (Sinev & Hollwedel, 2002)   , parthenogenetic female from Bonita Pond, Distrito Federal, Brazil. A, lateral view. B, lateral head pore. C, labral keel. D, postabdomen. E, limb I, IDL. F, limb II, scraper 1 and exopodite. G, limb II, scraper 7–8 and gnathobase. Abbreviations in Material and Methods. Scale bars = 50 µm.

Comments. One short seta on the exopodite of limb II (Fig 2 F). Morphology of the IDL setae (Fig 2 E), number of setae on the filter comb of limb II (Fig 2 G), and morphology of scraper 8 (Fig 2 G), as observed by Van Damme et al. (2011). However, the anal margin of the postabdomen is concave, not straight (Fig 2 D), and the seventh scraper on limb II has no denticles (Fig 2 G). Anthalona brandorffi   has also a variation on the labral keel and spinulae at the base of the postabdominal claw; some individuals of the populations from Central Brazil had a small denticle on the labral keel (Fig 2 C) as observed in A. acuta   and A. verrucosa (Van Damme et al. 2011)   . A spinule on the base of the postabdominal claw longer than the basal spine was observed in the studied populations (Fig 2 D), which had not been previously observed in any other species of Anthalona (see Van Damme et al. 2011; Sinev & Kotov 2012). Anthalona brandorffi   may be confused with A. verrucosa   , but differs in carapace setae (in A. brandorffi   the posterior setae are long) and postabdomen ( A. brandorffi   has long lateral spinules on the postanal fascicles). Besides that, scrapers 7–8 are strongly modified and different from those in other species of Anthalona (for morphology of A. verrucosa   , see Van Damme et al. 2011).

Distribution and ecology. Anthalona brandorffi   has a wide geographical distribution in the Neotropics ( Fig 6 View FIGURE 6 B). The range of the species goes from Central America to Central Brazil. Records of A. verrucosa   from southern South America need to be checked, since the two species may have been confused. In Bonita pond we observed A. brandorffi   , A. acuta   and A. verrucosa   coexisting in the macrophytes from the family Cyperaceae Juss.   and Pontederiaceae Kunth   beds. Thus, A. brandorffi   may coexist with other South American species of the genus.
