Habitus as in Fig. 19 . Body yellow-brown to reddish-brown, usually with darker head and abdomen; mouthparts, antennomeres 1–2 or 1–3 and legs yellow. Head without microsculpture except of apical part of clypeus with fine transverse microreticulation and latero-basal portions with fine subdiagonal meshes; neck with fine transverse sculpture; abdomen with fine transerse microsculpture. Head with relatively dense punctation, finer and sparser in frontal portion, larger and denser in middle, denser and deeper on infraorbial portions; punctation of pronotum distinctly denser, larger and deeper than that in middle portion of head, sparser and finer in mediobasal portion; punctation of elytra denser, slightly larger and deeper than that on pronotum, sometimes with indistinct longitudinal elevations between punctures in middle; abdominal tergites with fine and sparse punctation.

Head 1.7–1.9 times as broad as long, with distinctly elevated median portion; anteriomedian depression moderately wide and deep, connected with deep lateral depressions; anteocellar foveae moderately wide and deep, strongly divergent anteriad toward about level of middle length of eyes; postocular ridges acute, with interspace between posterior margin of eyes and ridge about as long as diameter of two-three ommatidia. Ocelli moderately large, located at level or slightly below level of postocular ridges; distance between ocelli 1.5–1.8 times as long as distance between ocellus and posterior margin of eyes. Antenna reaching basal third of elytra when reclined; basal antennomere about two and a half times as long as broad, 4–5 distinctly shorter than 3, 6–7 slightly shorter than 5, 8 indistinctly shorter than 7, 9–10 slightly broader than 8.

Pronotum 1.6–1.8 times as broad as long, gradually narrowed both anteriad and posteriad; distinctly more than twice as long as pronotum, reaching apical margin of abdominal tergite IV–V, indistinctly broadened toward preapical portion, with widely rounded apical angles; posterior angles obtuse, usually with slightly concave latero-basal margins; apical angles distinctly protruded anteriad; middle portion without or with shallow longitudinal impression and without or with indistinct semicircular mediobasal impression (some specimens without impressions).

Elytra about as long as broad, 1.1–1.2 times as long as pronotum, slightly broadened posteriad; some specimens with irregular elevations between punctures in mediobasal part and/or irregular two to three longitudinal elevations in middle; lateral portions narrowly impressed; latero-apical edges without or with indistinct small crenulation.

Male. Apical margin of abdominal tergite VIII straight or indistinctly sinuate. Apical margin of abdominal sternite VIII widely sinuate. Aedeagus wide, from basal part gradually narrowed apicad toward wide truncate or slightly sinuate apex; parameres moderately wide, significantly exceeding apex of median lobe, with four short apical setae; internal sac long and narrow ( Fig. 24 ). Lateral aspect of the aedeagus as in Fig. 25 .

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

Comparative notes. Based on the general shape of the body and the aedeagus, A. moczarskii is similar to widespread A. unicolor , from which can be distinguished by the denser punctation of the forebody, apical angles of pronotum more protruded anteriad, distinctly longer parameres and different details of the structure of the internal sac. Many specimens of A. moczarskii with distinctly reddish-brown body, while the body of A unicolor is fully yellowish.

Distribution. Anthobium moczarskii is widely distributed in the Iberian Peninsula ( Fig. 31 ).

Bionomics. Specimens were collected at elevations from 832 to 2020 m a.s.l. by sifting litter in deciduous and coniferous ( Pinus ) forests.

Remarks. Lathrimaeum moczarskii was originally described from “Süd-Spanien auf der Sierra Alfacar” based on three specimens. Prior to the present study, it was known only from the type material. Based on the vast material, it has been found that A. moczarskii is a common species in the Iberian Peninsula. It is here recorded from Portugal for the first time.
