Redescription. Measurements (n=15): HW: 0.67–0.70; HL: 0.45–0.50; OL: 0.20–0.25; LT: 0.08–0.10; AL (holotype): 1.69; PL: 0.62–0.70; PWMax: 0.72–0.80; PWMin: 0.60–0.66; EL: 1.50–1.63; ESL: 1.35–1.55; EW: 1.35–1.40; MTbL (holotype): 0.92; MTrL (holotype): 0.50; AW: 1.18–1.38; AedL: 0.82–0.86; FL: 2.62–3.18; TL: 3.20–4.00 (holotype: 3.90).

Body brown to reddish-brown, sometimes with slightly paler elytra; antennae and legs yellow-brown; mouthparts and tarsi yellow to yellow-brown. Punctation of head moderately large, sparser in middle and denser between longitudinal depressions and eyes; punctation of pronotum dense, slightly deeper than that of head. Habitus as in Fig. 11 .

Head 1.4 times as broad as long, with distinctly elevated middle portion, indistinct transverse impression at level of middle length of eyes and separated from lateral portions by very deep longitudinal depressions; eyes more than twice as long as temples. Antennae reaching one third of elytra when reclined, with slightly thickened antennomeres 7–10; antennomeres 2–7 approximately equal in length, 8–9 slightly shorter than 7, 10 about as long as and slightly broader than 9.

Pronotum slightly broader than long, about as wide as head, widest in anterior third portion, sharply narrowed toward subparallel latero-basal margins, with obtuse or subacute hind angles; mediobasal third of pronotum with distinct transverse impression.

Elytra about as broad as long, more than twice as long as pronotum.

Metatarsus less than twice as long as metatibia, with basal metatarsomere slightly shorter than combined length of tarsomeres 2–3.

Abdomen with paired transverse tomentose spots in the middle of abdominal tergite V.

Male. Apical margin of abdominal tergite VIII rounded. Apical margin of abdominal sternite VIII widely concaved.Aedeagus with very wide basal portion, strongly narrowed toward acute apex; parameres narrow, widened apically, distinctly exceeding apex of median lobe, with four long apical and preapical setae; internal sac moderately short and narrow ( Fig. 18 ). Lateral aspect of aedeagus as in Fig. 19 .

Female. Apical margins of abdominal tergites and sternites VIII rounded.

Comparative notes. Regarding the coloration, large and deep punctation of the pronotum, the shape of the apical margins of the elytra, and the length of the apical metarsomere, L. lusitana is similar to L. monticola and L. osellai sp.n. Regarding the shape of antennomeres it is more similar to L. monticola , from which it is distinguished by smaller body size and broader pronotum. From both these species, it differs by the shape of narrow median lobe, significantly longer parameres, and the different structure of the internal sac.

Distribution. The species is known from several localities in central Portugal and the north-western provinces of Spain ( Fig. 8 ).

Natural history. Specimens were collected at elevations from 450 to 1585 m a.s.l. Detailed ecological data are unknown.

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