Description of the 5th instar larva

(all morphological characters identical to those of Apataniana stropones except as noted below). Diagnosis. Setal transversal band at 1st abdominal dorsum interrupted at center; central submentum parallel-sided.

Biometry. Body length of 5th instar larvae ranging from 6.4 to 6.9 mm, head width from 0.76 to 0.83 mm (n= 3).

Head. Head reddish brown with paler, wedge-shaped areas from eyes to mandible bases and around anterior border of head capsule (Fig. 15). Labrum medium to dark brown. Submentum narrower than in Apataniana stropones , wedge-shaped, parallel-sided at center (Fig. 16); light to yellowish brown, with dark brown anterior, broadened section and medium brown posterior tip.

Thorax. Pronotum dark brown. Pentangular prosternite with medium brown transverse band; lateral sclerites indistinct. Mesonotum medium brown, posterolateral corners black (Fig. 19). Lateral sclerites with anterior groups of 10-20 setae per sclerite; anterior and posterior metanotal sclerites completely lacking and replaced by groups of setae: 10-28 at each anterior and 10-15 at each posterior metanotal position (Fig. 17). Mid tarsal claw shorter than half tarsal length (Fig. 18).

Abdomen. Setal transversal band at 1st abdominal dorsum interrupted at center, consisting of 30-40 setae (Fig. 17); setal group dorsal of lateral protuberance with 4-7 setae each. Ventral section of lateral protuberances and 1st abdominal sternum with continuous field of setae with basal sclerites minute and inconspicuous; total setal number is 120-140.

Dorsal gills present at 3rd segment (postsegmental position), ventral gills ranging from 2nd (postsegmental) to 6th segment (postsegmental). Lateral gills lacking.

Case. Fifth instar larval case 8.3_8.7 mm long (n= 3), curved, tapering posteriorly (width at anterior opening 2.5-4.9 mm and at posterior opening 1.5-1.8 mm).
