Dorsal shield oval, length 147 (143–152), width 62 (58–68). Anterior margin triangular, posterior margin rounded, weakly narrowed, with seven pairs of setae, first pair is longer than the other pairs and six pairs of large pores; pores surrounded by radially arranged short furrows; longitudinal lateral furrows not developed, distinct only in the intervals between the anterior margin and first pairs of pores; third pair of pores connecting by a transverse furrow (Figs. 1A, 2A). The ocular plates lie on each side of the dorsal plate with two separate lens-like structures, length 33 (28– 38) (Fig. 2A). Two triangular-shaped lateral plates lie posterior to the ocular plates, each lateral plate bears two side-by-side arranged setae, length 29 (28–30) (Fig. 2A). Measurements of body parts are given in Table 1.</p> <p>Gnathosoma; D. Palp; E. velum. Scale bar: 68 μm for A and B; 28 μm for C; 33 μm for D; 30 μm for E.</p> <p>Venter (Fig. 2B) – Coxal plates I and II are fused together, each with 2 setae, coxal plate III separate contains 2 setae; anal shield long, narrowed at both ends, lying between the posterolateral plates, two small pores situated in front of the excretory pore; posterior lateral plates lie posterior to coxae III, tapering to a point beside the excretory plate, each with 4 setae (Figs. 1B, 2B).</p> <p>Gnathosoma (Fig. 2C) – Mouthparts include the chelicerae, palps and rostrum that supported by basis capitulum. The stylophore consist of fused basal segments of the chelicerae that forms the dorsal cover for the mouthparts. Stylophore oviform, length 36 (33–42), anterior margin rounded, posterior margin weakly narrowed (Fig. 1E). The velum, which holds the mouthparts of the larva to the integument is on the ventral face of the rostrum. Velum with two rows of eight large papillae, proto- and tritorostral setae visible (Figs. 1C, 2E). Chelicera triangular in outline, pointed at tip, tip is weakly bent, its length exceeds than basal width. Pedipalp large, five segmented, trochanter short, discoid; femur and genu moderately developed, genu with a narrow medial crest, tibia with large furcate setae, with a developed wing-shaped branch, tibial claw length 23 (20–24), tarsus bilobed, with two normal setae and one solenidion (Figs. 1D, 2D).</p> <p>Legs (Fig. 3) – The number of leg setae from coxa to tarsus is 2-1-5-4-9-18; epimera I and II partly fused (Figs. 1B, 2B); legs terminate in two sickle-shaped claws (Fig. 3D); all legs have a trichobothrium on the dorsal surface of the telofemur (Fig. 3B); solenidion on tarsus II 22 (18–23) long (Fig. 3C); length of legs I-III respectively: I, 153; II, 156; III, 168; length of leg segments given in Table 1.</p> <p>Material examined</p> <p>Twenty larvae of Eylais extendens were separated from abdominal tergites of the water beetles of families Noteridae and Dytiscidae. Two larvae were separated from leg (femur) of water beetles of family Heteroceridae (Fig. 4).</p> </div>	https://treatment.plazi.org/id/03AA87C0B73696561C4F0566E9059A11	Public Domain	No known copyright restrictions apply.
