Redescription. Measurements (n=15): HW: 0.70–0.92; HL: 0.50–0.62; OL: 0.20–0.26; LT: 0.11–0.15; AL (mean): 2.30; PL: 0.63–0.85; PWMax: 0.84–0.96; PWMin: 0.59–0.70; EL: 1.38–1.65; ESL: 1.11–1.45; EW: 1.23– 1.53; MTbL (averaged): 1.00; MTrL (averaged): 0.60; AW: 1.14–1.44; AedL: 0.67–0.75; FL: 2.87–3.05; TL: 3.00– 4.80 (holotype of L. mateui : 4.20).

Body yellow-brown to brown, with slightly paler elytra; antennae and legs yellow to yellow-brown, with darker apical portion of femora and sometimes tibia; mouthparts and tarsi yellow. Punctation of head dense and fine, slightly larger in middle and denser between longitudinal depressions and eyes, distance between punctures in middle about as broad as nearest puncture; neck with punctation similar to that of middle portion of head; punctation of pronotum denser and sometimes finer than that of head, slightly sparser in medioapical and mediobasal portions; scutellum with very fine and moderately dense, irregular punctation; punctation of elytra distinctly sparser and coarser than that of pronotum. Habitus as in Fig. 13 .

Head with markedly convex middle portion and very deep longitudinal depressions; eyes small, about twice as long as temples; distance between ocelli markedly shorter than distance between ocellus and posterior margin of eye. Antennae reaching anterior third or middle length of elytra when reclined, with long antennomeres 4–10; antennomeres 3–7 of approximately equal length, 8–10 slightly shorter and broader than 7.

Pronotum 1.1–1.3 times as broad as long, markedly broader than head, usually very wide in anterior portion.

Elytra distinctly broader than long, about twice as long as pronotum, significantly widened apicad.

Basal metatarsomere slightly longer than combined length of tarsomeres 2–3 and distinctly longer than apical metatarsomere.

Male. Apical margin of abdominal tergite VIII convex. Apical margin of abdominal tergite VIII concave. Aedeagus with moderately wide basal portion, gradually narrowing toward median lobe and slightly widened in apical third, with sharply narrowed apical portion and subacute apex; parameres nearly reaching apex of median lobe; internal sac long and moderately wide ( Figs. 23, 25, 27 ). Lateral aspect of aedeagus as in Figs. 24, 26, 28 .

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

Comparative notes. Regarding body, size, coloration, the punctation of the forebody, the proportions of the antennomeres, and the shape of the elytra, L. mateui is similar to L. mariei (see above), from which it is distinguished by slightly longer elytra, a narrower median lobe with a differently shaped apical portion, the length of the parameres, and a different structure of the internal sac.

Distribution. The species is distributed in South Spain ( Fig. 8 ).

Natural history. Specimens were collected at elevations from 1300 to 2900 m a.s.l. The specimens from Rio Nante (Sierra Nevada) were taken from wet mosses near the confluence of a stream and a river.

Remarks. Lesteva mateui was originally described from several localities of Sierra Nevada. Lesteva cobosi was described from Sierra de Cazorla ( Coiffait 1970) and later synonymized with L. mateui by Lohse (1987). In the same article, Lohse presented a new species without description: L. cazorlana Lohse, 1987 , referring to specimens with somewhat larger eyes and a longer median lobe, which had been identified by Coiffait as L. mateui and illustrated by him in Figs. 3 g-i ( Coiffait 1970). Lohse designated the specimen from his collection (see above) as the holotype of L. cazorlana . A study of material of this morphologically variable species revealed no significant differences between specimens from different localities. The proportions of the longitudinal length of the eyes in relation to the length of the temples, the width of the pronotum, and the apical portion of the median lobe may vary even in material from the same locality ( Figs. 23, 25 ). Thus, L. cazorlana is synonymized with L. mateui .
