description: Stenopsyche sp. 1
(Fig. 11)
Larva (5th instar). Body length 43 mm. Head and pronotum strongly sclerotized. Head: length 5 mm, width 1.25 mm (n=3), subrectangular, setae brown, long. Ground color brown, with distinct punctate pattern as follows: frontoclypeal apotome with dark stripes and spots forming ghost face; other portions of head capsule with scattered dark spots or stripes of coalesced black dots, and dark stripe along ventral ecdysial line in ventral view. Eyes small, eye areas large, pale. Labrum dark brown mesally and light brown laterally, with 2 hair brushes at anterior margin. Frontoclypeus yellow, with 3 indistinct longitudinal pale lines separating 4 rectangular darker areas. Mandibles dark brown basally and black distally, in ventral view with 4 apical teeth, only left mandible with mesal brush of stiff hairs. Mentum semicircular, anterior margin with mesal tongue-like lobe, single seta on each side. Anterior ventral apotome black, triangular, about 1/8th as long as ventral ecdysial line. Pair of #18 setae near posteroventral margin with each seta located at center of dark brown triangular spot and posterior to base of ventral ecdysial line; distance from each seta to posteroventral margin shorter than distance of that setae to ventral ecdysial line (d1:d2 = 1:1.67).
Thorax: Pronotum heavily sclerotized, subrectangular in dorsal view, ventrolateral margin sinuous in lateral view, brown, mesal basodorsal portion with -shaped pattern of coalesced dark dots, laterally with semicircular pattern of dark dots; anterior half of each lateral margin with dark stripe connected with elongate black stripe just above insertion of forecoxa; anterior margin fringed with hairs. Foretrochantins in ventrolateral view rhomboid, long; episterna small, subtriangular in lateral view; epimera surrounding forecoxae posteriorly, in ventral view each rectangular, with its anterior margin concave, posterolateral margin black. Forelegs each with forecoxa short, cylindrical, with 2 black conical processes at anterior margin in lateral view, basal process triangular and apical one slender. Femur cylindrical, progressively wider from base to apex in lateral view, outer side with dark brown longitudinal line and 3 dark brown rings above line, inner side with longitudinal indentation; tibia and tarsus slender, progressively shorter, tarsus with row of hairs on inner side along lower margin from basal 1/5th to apex; claw curved downward with small finger-like ventral process at base. Mesonotum and the metanotum membranous. Mesonotal setae arising in sa 1, sa 2 and sa 3, each with 1 seta. Middle and hind legs nearly equal in length, yellowish brown; femora slightly broader apically, punctate; claws bifid, hook-like.
Abdomen: Almost uniformly broad, greenish grey in live specimens, brownish in alcohol, with scarce setae. Anal prolegs brown, stout, with few dark setae; claws hook-like.
