Total body length 0.9−1.1 mm (for morphometric characters see Table 4). Pediger 4 and pediger 5 posterolaterally bearing long fine hairs and thick (spinule-like) hairs, respectively (Fig. 8 A−B) – pilosity of pediger 4 could only be verified in females from Kirando, Lake Tanganyika. Genital double-somite (Fig. 8B) as long or slightly shorter than wide. Seminal receptacle as common in genus (Fig. 8B), anterior and posterior parts short in length, posterior part wider than anterior, single large copulatory pore in anterior fifth of somite. Anal operculum (Fig. 8D) nearly straight, anal sinus with longitudinal rows of hairs, posterior margin bearing continuous row of robust spinules. Caudal rami (Fig. 8D) 4.0−6.0 times as long as wide, no hairs on medial margin. Serra extending from insertion of anterolateral (II) caudal seta to anterior ⅕−⅙ of rami. Seta II inserted in posterior ¼−⅕ of caudal ramus. Spinules present next to insertion of posterolateral (III) caudal seta. Relative length of caudal setae in Table 4.</p> <p>ANTENNULE. 12-segmented, reaching middle length to posterior margin of pediger 2. Setation formula same as in E. azorensis. Aesthetasc (Fig. 7A) on segment 9 short, ~12 μm in length, not reaching distal margin of segment. Segments 10−12 with smooth (very finely serrate) hyaline membrane. First antennular segment bearing spinules on ventral surface, spinules absent on other segment. Terminal antennulary segment 5.0−7.1 times as long as wide.</p> <p>ANTENNA. Composed of coxobasis and three-segmented endopodite, and bearing 3, 1, 9 and 7 setae, respectively. Exopodite seta reaching slightly (paratype, Lake Victoria) or distinctly (Kirando, Lake Tanganyika) beyond enp3, proximal setules can be similar in length or distinctly longer than setules in distal section of seta (Figs 7B, 8F). Caudal surface ornamentation of antennal coxobasis (Figs 7B, 8E) with same groups of spinules as those in E. azorensis in lateral half of segment, except for additional group of spinules next to distal margin (group marked with arrow in Fig. 7B). Medial half of segment with reduced ornamentation: few spinules sometimes present at height of insertion medial setae (Fig. 7B), or below setae (Fig. 8E). Frontal surface (Figs 7C, 8F) adorned with spinule-like hairs next to distal margin, hairs absent mediodistally, longitudinal/oblique row of spinules (8−13) along lateral margin, and oblique rows of large and small spinules near proximal margin.</p> <p>MOUTHPARTS. Labrum (Fig. 8G) with naked epistoma, distal fringe hairs arranged in two groups, teeth acute on distal rim, obtuse lateral lobes with tiny spinules. Paragnaths (Fig. 8H) bearing longitudinal rows of hairs on outer (ventral) surface, longitudinal row of spinules more dorsally (indicated by dotted line in Fig. 8H), mediodistal lobe with group of spinules. Four medial claw-like elements (three inserted close to each other and one inserted more distally) located slightly dorsally to hairs on outer (ventral) surface (not shown in figure). Long spinules present posterior to paragnaths. Mandible (Figs 7D, 9A) bearing two long and one short seta. Near palp transverse row of long spinules and smaller spinules arranged in row rather than oval pattern present on anterior surface of gnathobase. Maxillulary palp (Figs 7D, 9 B−C) with few spinules arranged in discontinuous row/arc. Setation of maxilla (Fig. 9 D−E) as common in Eucyclops, endopodite 2-segmented. Praecoxopodite and coxopodite separated on caudal surface and partially fused on frontal surface; short transverse row of spinules present near lateral margin on caudal surface (Fig. 9E, marked with arrow). Armature of maxilliped (Fig. 9 F−G) as common in Eucyclops, arthrodial membrane between terminal endopodal segment and its medialmost seta failed to form. Basipodite with two rows of spinules on caudal surface. Tiny dents on free margin of flap-like structure (Fig. 9G, marked with arrow) sometimes present (maxilliped could be verified in specimens from Kirando, Lake Tanganyika).</p> <p>P1−P4. Setation formula same as in E. azorensis (Table 2). P1 intercoxal sclerite (Fig. 9H) naked on both frontal and caudal surfaces in all specimens examined (one paratype from Lake Victoria and three females from Kirando, Lake Tanganyika). P2−P3 intercoxal sclerites (Fig. 10 B, D): hairs arranged in two groups present on frontal surface in both legs; transverse row of spinules present or absent on caudal surface in P2 and present in P3. P4 intercoxal sclerite (Figs 7E, 10E) caudally bearing hairlike spinules in two (three) rows, free margin avoid of hairs in middle; frontal surface naked. Coxopodite setae with long and fine setules in P1, and short and thick setules in P2−P4 (Figs 9H, 10B, D−E). P4 coxopodite seta lacking setules in short proximal section on lateral margin (two ♀♀, Kirando, Lake Tanganyika) – whole length (continuous) setulation shown in Sars (1909). Caudal surface ornamentation of P4 coxopodite (Figs 7E, 10E) as common in genus; number of spinules 20, 21 (two ♀♀, Kirando, Lake Tanganyika) in transverse row along distal margin. Medial expansion of basipodites pilose in P1−P4. Medial seta of P1 basipodite (Fig. 9H) with short setules, seta reaching beyond distal margin of enp2. Second exopodal segment laterally pilose, exp1 and exp3 laterally naked in P1−P4 (Figs 7 E−F, 9H−I, 10A, C, E−F). P4 enp3 (Figs 7G, 10G) 2.2−2.4 times as long as wide, medial terminal spine 1.4−1.5 times as long as lateral spine, and about as long as segment (Table 4). None of setae of P4 enp3 reaching beyond tip of longer (medial) terminal spine.</p> <p>P5 (Fig. 8C). One-segmented, with three appendages. Medial spine distinctly longer than segment (Table 4), small spinules present at insertion of spine. Apical seta 1.4 (paratype, L. Victoria) to 2.3 (Kirando, Lake Tanganyika) times as long as medial spine, lateral seta and medial spine subequal in length.</p> <p>Male</p> <p>Unknown.</p> <p>Geographic distribution and habitat preferences</p> <p>Eucyclops agiloides has been reported from various regions of Africa, Asia and even Eastern Europe: Lake Malawi (Alekseev &amp; Defaye 2011), Ethiopia (Defaye 1988), Nigeria (Boxshall &amp; Braide 1991), Northern Algeria (Hamaidi et al. 2010), Crimea, Lesser Caucasus and Talysh region (South Azerbaijan) (Monchenko 2003), China (Tai &amp; Chen 1979 − E. agiloides was considered by these authors as a synonym of E. serrulatus), India (Kiefer 1939; Lindberg 1939; Dev Roy &amp; Venkataraman 2018), Sumatra and Java (Kiefer 1933), and Borneo (Alekseev et al. 2016). Part of these records may refer to other taxa (e.g., E. roseus), and the geographic distribution of the species is still poorly understood (Fig. 11 shows only the verified records). The same holds true for the habitat preferences of E. agiloides. The specimens examined here were collected in large lakes and a river mouth in Lake Tanganyika, yet precise information on the collection sites is missing.</p> </div>	http://treatment.plazi.org/id/03BC87DD925EBF23A960A736D151FE37	Public Domain	No known copyright restrictions apply.
