03DCB256FFF9FFD2FE632B64DB71FA64.taxon	description	Male: size 0.55 mm, valves dorsally not oval, posterior-dorsal angle pointed, antennulae rather long, post-abdomen similar to female, claw with setules, but no pecten.	en	Dartnall, Herbert J. G., Hollwedel, Werner (2007): A limnological reconnaissance of the Falkland Islands; with particular reference to the waterfleas (Arthropoda: Anomopoda). Journal of Natural History 41 (21 - 24): 1259-1300, DOI: 10.1080/00222930701401010, URL: http://dx.doi.org/10.1080/00222930701401010
03DCB256FFFEFFD4FE8F2B69DB60FA44.taxon	description	Adult female: 2.5 – 3.25 mm; valves oval with a depression between head and dorsal margin. The latter and posterior half of ventral margin with small denticles, the central third of inner ventral margin with a row of longer setae directed inward and posteriorly. Shell spine short or completely reduced. Head high, anterior rounded, ventral margin straight or slightly concave; rostrum pointed, antennulae do not reach the tip of rostrum; ocellus extremely small. First abdominal process double the length of the second, the former curved anteriorly and covered with setules, the latter curved posteriorly and thinly covered with setules, the third and fourth processes are small protruberances. Postabdomen (Figure 15) long and broad, narrowing distally, dorsal margin slightly concave with 16 – 19 post-anal denticles, post-abdominal claw stout with two pectens, a proximal one with seven to nine smaller denticles, and a distal one with 9 – 12 longer denticles (Figure 16). Juvenile female: ventral margin of valves broadly rounded, the whole length covered with denticles, dorsal margin straight, and denticulate, passing over a dorsally directed shell spine, nearly as long as body. Ventral margin of head equally convex, no rostrum, eye near the margin, ocellus not visible; head bearing a rounded horn directed obliquely backward (Figure 17), as in Daday de Dées’s illustration (1902, Table 12, Figure 9) and Paggi’s drawing (1999, p. 32, Figure 45). Villalobos (1994) mentions that some of her juvenile specimens from South America have ‘‘ a little helmet’ ’. A similar horn seems to occur in other species. Rane (1986) describes and illustrates juveniles of Daphnia sarojae Rane with a helmet that is similar to the Falkland D. dadayana, but note that Sharma and Sharma (1990) believe Daphnia sarojae to be a helmeted morphotype of D. lumholtzi.	en	Dartnall, Herbert J.

03DCB256FFFFFFD7FE3C2A8FDDF7FB9A.taxon	description	Female: 1.42 – 1.65 mm, valves broad and oval, dorsal and ventral margin with denticles, inner ventral margin without setae, shell spine short or absent, all juveniles with spines; ventral margin of head concave; antennulae do not reach tip of rostrum. Post-abdominal claw with a pecten of eight to nine denticles. Juvenile male: 0.62 – 0.95 mm; anterior ventral margin with long spines; rostrum short; antennulae nearly as long as flagellum, not on a curved projection. Second abdominal projection relatively short, not reaching the root of abdominal setae; dorsal margin of postabdomen straight as in D. obtusa. Daphnia pulex was reported from the Falkland Islands by both Smith and Sayers (1971) and Brooks et al. (2005). According to Benzie (2005) the occurrence of D. pulex in South America is doubtful, suggesting our specimens may belong to a different species. This needs clarification.	en	Dartnall, Herbert J.

03DCB256FFE2FFCBFE792EDDDE62F902.taxon	description	Female: 0.6 mm, brown colour, valve with ridge, one denticle at the postero-ventral angle, rostrum longer than labrum, tip of rostrum rounded, anal and post-anal segments of post-abdomen equally long (Figure 22), but both longer than pre-anal region, postabdominal claw stout with two basal spines, the longer one nearly as long as width of claw, shorter one half as long.	en	Dartnall, Herbert J.

03DCB256FFE2FFCBFE792EDDDE62F902.taxon	description	Two cyclopoid copepods were identified in the field. One of these, a stream-dwelling species from Fox Bay, thought to be Tropocyclops meriodionalis, is sometimes treated as a subspecies of T. prasinus (G. Boxshall, personal communication). The other cyclopoid was subsequently determined to be two species including a larger Acanthocyclops michaelseni and a smaller Diacyclops sp. possibly D. (Acanthocyclops) mirnyi (G. Boxshall, personal communication, who considers the original descriptions of both taxa inadequate and in need of revision). Harpacticoida: a few small specimens were observed. These have been assigned to two (unidentified) Canthocamptidae one of which was also present at South Georgia (G. Boxshall, personal communication). Attheyella trigonura (Ekman) has been reported from the Falkland Islands (Ekman 1905; Pugh et al. 2002). Ostracoda: only one species, Newnhamia patagonica, a new record for the Falkland Islands, was observed.	en	Dartnall, Herbert J.

03DCB256FFE2FFCBFE792EDDDE62F902.taxon	description	Trichoptera: two types of caddis fly larvae were recognized in the field: (1) those that make their protective tubes from reeds and other detritus pieces, and (2) a smaller larva with a transparent flattened cone-shaped tube, open at both ends. The reed-cased specimens comprise two Magellomyia spp., including M. appendiculata (Ulmer), with a uniformly coloured head and a slightly curved tube, and Magellomyia stenoptera Schmid, which has a banded head and straight tube. This distinction was not known at the time of the collection when specimens were pooled. The transparent-cased caddis is an Oxyethira spp. probably O. bidentata Mosely though both O. andina Kelley and / or O. vipera Kelley, known from southern Chile and Argentina, are also potential contenders (I. Wallace, P. Barnard and O. S. Flint Jr, personal communication). No caddis larvae were found on either Sea Lion or Pebble Islands. Coleoptera: two species of diving beetle were found, Lancetes falklandicus and a much smaller bidessine (G. Foster, personal communication). Both are powerful swimmers able to avoid slowly trawled plankton nets but were collected in hand nets and are probably more widespread than indicated. Hemiptera: unidentified specimens of waterboatman were observed at both Pebble Island and Fox Bay. These powerful swimmers can avoid nets and are probably more widespread than indicated. These records represent the first report of waterboatmen from the Falkland Islands. Chelicerata. Acarina: only two specimens were found, in the Felton Stream near Stanley and in a stream by the Hawk’s Nest Shanty pond. They have been identified as Soldanellonyx monardi Walter and Mucronothrus nasalis (Willmann), both of which are ‘‘ cosmopolitan’ ’ freshwater species (P. J. A. Pugh, personal communication). Vertebrata Two species of fish were found in this survey, the Falkland Island minnow Galaxias maculates (Jenyns) and the Falkland Island trout Aplochiton zebra Jenyns. Both are diadromous though landlocked populations are known (McDowall et al. 2001). Neither was particularly common and solitary individuals were usually obtained in hand net sweeps but were noticeably absent from the very small water bodies around Stanley and from Sea Lion Island.	en	Dartnall, Herbert J.
