ZML, published in Aubert 1956). <b>Male genitalia</b> (Figs. 3, 9-10, 16-19). Paraprocts: Median lobe with a rounded base and a blade-shaped expansion with variable length (Aubert 1956: Figs. 9- 10); outer lobe sclerite widely enlarged at the tip, with a rounded dorsal expansion carrying few strong spines (1–7) and a rather long and thin ventral expansion, curved inwards, and ending in one or two spines (Fig. 19 and Aubert 1956: Fig. 9, Raušer 1963: Fig. 3a). Epiproct: Thin, with its sides slightly convex, ending progressively in an oval tip; terminal filament of moderate size and bifid at the tip (Figs. 10, 16). In side view the terminal filament is about parallel to the epiproct but it can be slightly rising due to the condition of the specimen (Figs. 3, 9). Lateral sclerites thin, visible by transparency, and slightly curved upwards on each side of the epiproct’s tip. Ventral sclerite with a prominent bulge partly covered with two rows of long spines forming a ‘V’ shape in ventral view (Fig. 3 and cf. <i>P. pectinata</i> Berthélemy &amp; Dia 1982: Fig. 23). Sternite IX: Vesicle racket-shaped and widening at the tip (Fig. 17 and Aubert 1956: Fig. 7), but this character is rather variable. <b>Female genitalia</b> (Figs. 20-21). Subgenital plate slightly concave, with rounded vaginal lobes. Sternite VII with a postero-median pigmented pregenital plate. <b>Mature larva</b> (Figs. 22-27, 75). Body relatively slender, body length 6.5–9.0 mm. General colour brown. Pilosity distinct. Scales present only in the dorsal midline of the femora and on the tarsi. Legs typical of the genus, tibiae slightly longer than femora; width of hind femora less than one third of its length. Head stout, brown with dark patches. The pronotum is subtrapezoidal, with distinct granules and rounded corners; it is slightly narrowing towards the posterior margin and its length is more than two thirds of its maximum width. Cervical gills simple, the longest one equivalent to the width of the fore coxa. Wing pads shortened or of typical length for the genus. Abdomen relatively slender, integument light and matt, first 6 abdominal segments divided by pleura. Posterior margin of sternite IX of the mature male larva triangular, tip rounded; paraprocts slightly elongated but not pointed (Fig. 75 and Aubert 1956: Figs. 13-14). Genital opening well visible on the mature female larva, and placed under the anterior half of sternite VIII; paraprocts not pointed (Aubert 1956: Fig. 15). Cerci long, with more than 30 segments; segment sides nearly parallel, the width of segments 13–17 is three fifths of their length. Pilosity: Head with dense, stout bristles, and a few sensilla; the eyes bear small setae between the ocelli. Antennal segments with short pilosity. Pronotum with dense, stout and blunt bristles, and a few sensilla. Margin of the pronotum bearing acute bristles, the length of the longest ones is less than 1/15 of the pronotum’s width (Fig. 22). The bristles on the anterior corners of the meso and metanotum are as long as the marginal bristles of the pronotum. The setae placed in lines on the wing pads are short and blunt. Legs with dense setation. All femora bear both short and long, acute bristles and a few thin hairs. Long bristles occur mostly on the outer surface; on hind femora they are placed on the apical half. Bristles not in a regular arrangement; the longest ones reach one fourth of the femur’s width on the first pair, one fifth on the hind legs (Figs. 23-24). A bald median line is conspicuous on the dorsal surface of all femora and it is covered with rounded scales. Tarsi relatively slender, covered with thin hairs and bristles, metatarsi with triangular scales on the dorsal surface; apical spike of tibiae short. Tergal segments with acute bristles and thin hairs. Paired spines on the posterior margin acute, not much longer than the other spines of the row; on tergite V they reach more than one fourth of the segment’s length (Fig. 25). Distal margin with tiny triangular spikes around the row of bristles. Cercal segments with acute bristles, blunt or thin ones occur only in the apical whorl (Figs. 26-27). The apical whorl on segments 13-15 is a set of 13–16 strong, acute spikes mixed with short, blunt and short, thin setae. Longest bristles reach one third of the segment’s length on segments 13–15. <b>Affinities.</b> In the male, the outer lobe of the paraprocts has a characteristic ventral finger-shaped expansion, and the epiproct is slender at the tip. In <i>Protonemura algirica</i>, <i>P. berberica</i> and <i>P. dakkii</i> sp. n., it is stronger at the tip, with wide rounded apex. The female is very close to that of <i>P. dakkii</i> sp. n. The larva is very similar to those of <i>P. dakkii</i> sp. n. and <i>P. berberica</i>, and only the pharate males can be identified with sure, on the basis of the male imago terminalia under the larval skin. However, it differs by its darker habitus and the frequency of stout, blunt bristles on the pronotum, tergites and femurs. <b>Geographical distribution and ecology.</b> <i>P. talboti</i> is a west Maghrebin species inhabiting the Rif, the Middle and High Atlas, and the Tlemcen Mountains in western Algeria (Fig. 6). It occurs in mountain springs and brooks at various altitudes (85–2900 m). The specimens collected in the highest localities of the High Atlas are brachypterous.
