Kurzia (Kurzia) latissima (Kurz, 1875) View in CoL s. lat.
( Figs. 1 View FIGURE 1. A and 2 View FIGURE 2 )
Length: 0.652 (parthenogenetic female) & 0.664 mm (sexual female).
Shape. Body sub-rectangular, compressed laterally, dorsal margin curved and tapering posteriorly, maximum height near the middle ( Fig. 2 View FIGURE 2 B).
Carapace lined with longitudinal lines, more conspicuous in parthenogenetic females, dorsal margin evenly arched, postero-ventral angle rounded, ventral margin lined with sub-equal setae starting anteriorly with long setae followed by short setae in the middle continued again by long setae which decrease in size posteriorly. Ventral margin of valves concave in middle bearing feathered setae longer at the anterior portion of the margin, decreasing in size in its middle and increasing in size at the posterior region ( Fig. 2 View FIGURE 2 B).
Head with a relatively short rostrum, ocellus smaller than compound eye situated closely to eye than to apex of rostrum ( Fig.1 View FIGURE 1. A C; Fig. 2 View FIGURE 2 B). Three connected circular major head pores ( Fig. 2 View FIGURE 2 C).
Labrum roughly sub triangular in shape, labral keel with a somewhat wavy anterior margin and bluntly pointed apex ( Fig.1 View FIGURE 1. A C; Fig. 2 View FIGURE 2 A).
Antennule long, narrow with nine aesthetascs which project well beyond the tip of rostrum. Antennal to rostral length is 0.8:1 ( Fig.1 View FIGURE 1. A C; Fig. 2 View FIGURE 2 B).
Antenna thin, setal formula: 0-0-3/1-1-3 and spine formula 1-0-1/0-0-1. The spine on basipodite undersized, not easily seen, terminal spines almost equal in length (full setae not illustrated due to damaged antennae) ( Fig. 2 View FIGURE 2 D)
Trunk Limb I with two longer IDL setae uniformly and finely serrated, smallest seta lined with small spine like setules ( Fig. 2 View FIGURE 2 G)
Postabdomen long, slightly tapering distally ( Fig. 2 View FIGURE 2 E), distal angle not projecting beyond base of claw ( Fig. 2 View FIGURE 2 F), preanal angle distinct, anal margin slightly concave or straight, distal angle with 2 marginal teeth, 7–8 marginal teeth on postanal margin, about 11 groups of lateral fascicles (each with the anterior most member longer than others) ( Fig. 2 View FIGURE 2 E) Terminal claw long, curved distally with a single basal spine twice long as basal diameter of terminal claw, basal spine without serrations, 4-5 fine setules on basal margin. Concave margin of the claw with two groups of setules, first group of setules increase in length distally and the second group of smaller setules similar in size almost reach the tip ( Fig. 2 View FIGURE 2 E).
Ephippial female and Ephippium. Similar to parthenogenetic female in overall characters with central part of the valves darkened and with distinct curved markings. Single oval resting egg present ( Fig. 1 View FIGURE 1. A D). Male. Not found.
