995487A7FF94FFD6FF6BFC0F2480FE2C.taxon	description	Biometry. Body length ranging from 16.4 to 17.5 mm, head width from 1.08 to 1.39 mm (n = 13). Soft body parts (mesonotum, metanotum, and abdomen) of live specimens green dorsally, pale green ventrally. Specimens in alcohol, purplish-green or purplish brown dorsally; lightly coloured ventrally. Sclerotised areas (head, pronotum, legs, abdominal dorsum IX and anal prolegs) light brown or yellowish with dark brown or black markings (Figures 1 – 17). Head. Head capsule elongated, yellowish brown, with lateral margins almost parallel, slightly convergent anteriorly, with slight constriction at eyes (Figs. 1 – 8). Broad, transverse brown or light brown band across posterior 1 / 3 of frontoclypeus and adjacent sides of head interrupted by thin pale lines along frontoclypeal sutures, broad pale areas along coronal suture, and pale areas surrounding primary setae, especially setae 15 and 16 (Figs. 1 – 6, 9). Conspicuous brown muscle attachment spots at dorsal and lateral sides of parietalia, and along coronal suture (Figs. 1 – 6, 9). Dark brown marking at aboral end of frontoclypeus forming spade- or heart-shaped with crescentic row of four characteristic light muscle attachment spots (Figs. 1 – 6, often inconspicuous). Anterior edge of frontoclypeus (anteclypeus) almost straight, margined by light brown. Ventral view pale yellow except pale brown anterior and posterior margins, without any spots (Figs. 7 – 8). Ventral apotome triangular, light brown or yellowish, merged with rectangular submentum (Figs. 7 – 8 sm). Mouthparts (Figs 4 m, 8) and labrum (Figs 1 – 3 lb) typical of the genus. Thorax. Pronotum trapezoidal, covered by two large sclerites tapering posteriorly, wider than head capsule (Fig. 10). Yellowish and usually with few darker attachment spots in anterior half; posterior half mostly covered by transverse brown band bearing group of dark attachment spots, not always visible (Figs. 6, 10 tb). Posterior and lateral margins thickened and darkly striped, including anterolateral corners (Figs. 9, 10). Legs pale brown, with numerous setae on coxae, trochanters, and femora; tibiae and tarsi brownish with few smaller and thinner setae (Figs. 11 – 14). Forelegs shorter and stronger than mid- and hind legs. Forefemora distinctly wider than mid- and hind femora. Tarsal claws long and slender, curved, pointed, each with basal spur (Figs. 11, 12, 14). Thoracic gills with slender, long filaments arising laterally from two basal branches above each coxa, characteristic for the Rhyacophila s. str. Group (Figs. 12 – 14). Abdomen. Abdomen slightly flattened dorsoventrally (Fig. 16); most specimens in alcohol pale brown to yellowish-green ventrally and darker purplish-brown to purplish-green dorsally. Tufted gill filaments present on each side of segments I to VIII each arising from common base (Figs. 15, 16). As in all species of Rhyacophila s. str., tracheal gills each consisting of short, thick ventral branch (vb) with numerous filaments near apex, and longer, more-slender dorsal branch (db) with numerous filaments on its dorsal side (Figs. 15, 16). Dorsal sclerite on segment IX (Fig. 17) trapezoidal and light brown in colour, with a darker posterior margin. Setae at posterior end long and black (Fig. 17). Anal appendages each with proximal sclerite (Fig. 18 b) with ventral basal hook (Fig. 18 h) and with long lateral sword process (Figs 17, 18 sp), extending beyond suture line but shorter than anal claw; anal claws each with three ventral teeth (Fig. 18 ac).	en	Karaouzas, Ioannis, Ibrahimi, Halil, Waringer, Johann (2018): The larva of Rhyacophila palmeni McLachlan 1879 (Trichoptera: Rhyacophilidae) from Greece and Kosovo with notes on ecology and zoogeography including a key to the known Greek Rhyacophila larvae.
