Redescription. Measurements (n=30): HW: 0.68–0.81; HL: 0.46–0.68; OL: 0.17–0.23; LT: 0.12–0.16; AL (holotype): 1.80; PL: 0.65–0.83; PWMax: 0.85–1.02; PWMin: 0.56–0.77; EL: 1.33–1.58; ESL: 1.16–1.41; EW: 1.38–1.61; MTbL (holotype): 0.90; MTrL (holotype): 0.47; AW: 1.28–1.49; AedL: 0.70–0.85; FL: 2.58–3.27; TL: 3.75–4.65 (holotype: 4.00).

Body brown or reddish-brown, sometimes with somewhat paler elytra and apical abdominal tergites; antennomeres and legs yellow-brown to brown (sometimes antennes paler); mouthparts and tarsi yellow. Punctation of head dense, fine and moderately deep, sparser in middle and between ocelli, finer and denser around eyes; punctation of pronotum similar to that in middle portion of head, but markedly denser, with interspaces between punctures in middle as wide as diameters of nearest one-two punctures, sparser in mediobasal portion; punctation of elytra regular, sparse, larger and deeper than that in pronotum, finer in prescutellar and sometimes along suture; abdominal tergites without distinct punctures. Lateral portions of head around eyes sometimes with indistinct fine meshes; pronotum usually without microreticulation, but some specimens with very fine and indistinct transverse meshes in medioapical third; abdominal tergites with distinct isodiametric microsculpture. Habitus as in Fig. 12 .

Head 1.1–1.4 times as broad as long, widely elevated in middle; middle portion separated from lateral portions by very deep and moderately wide longitudinal depressions; eyes about one and a half times as long as temples. Antennae with elongate antennomeres; basal antennomere disitnctly more than twice as long as broad, 2 significantly narrower and shorter than basal antennomere, 3 slightly longer than 2, 4 slightly broader than 3, 5–8 slightly narrower and about as long as 4, 9–10 slightly shorter and wider than 8, apical antennomere about 1.4 times as long as 10, from about middle shaprly narrowed toward acute apex.

Pronotum 1.2–1.3 times as broad as long, 1.2 times as broad as head, from their widest apical third sharply narrowed toward subparallel latero-basal margins; dorsal surface sometimes with paired oval impressions in about middle and without or with indistinct, transverse mediobasal impression.

Elytra slightly broader than long, 1.6–1.7 times as long as pronotum, significantly widened toward hind angles.

Male. Apical margin of abdominal tergite VIII rounded. Apical margin of abdominal sternite VIII deeply concave. Aedeagus with wide moderately median lobe, from apical third significantly narrowed toward small, rounded apex; parameres slightly exceeding apex of median lobe; internal sac wide and long ( Figs. 20, 22 ). Lateral aspect of aedeagus as in Fig. 21 .

Female. Apical margins of abdominal tergite VIII and sternite VIII rounded.

Comparative notes. Regarding the general shapes of the body and antennomeres, body size and coloration, L. (s.str.) mariei is similar to the Iberian L. (s.str.) mateui , but differs by shorter elytra, the shape of the median lobe and length of the parameres (for details see the key below).

Distribution. Lesteva mariei is widely distributed in the Pyrenees and Cordillera Cantabrica ( Fig. 8 ).

Natural history. Specimens were collected at elevations from 1200 to 2300 m a.s.l. Detailed ecological data are unknown, but some specimens from Spain were collected by sifting wet mosses near streams.

Remarks. Lesteva mariei was originally described from several localities of the French Pyrenees.

The species is here recorded from Spain for the first time.
