Speonemadus brusteli sp. n.

Figs 1 , 6 , 14

Type locality: Morocco, Talembote , Moroccan fir ( Abies marocana ) forest of Talassemtane, 35°5'N 5°8'W, 1400 m .

Type series: Holotype: ♂: " Hervé Brustel leg. / MO Rif Talembote / (Sapinière) Talassemtane / 10/13 XI 2015" [printed], " HOLOTYPUS / Speonemadus / brusteli sp. n. / JF-AF-HF-IR det. 2016" [red label, hw]; aedeagus mounted in Canada balsam on a transparent microslide pinned with the specimen (MNHN). Paratypes: 15 exs, same labels as holotype, except " PARATYPUS " instead of " HOLOTYPUS " ( CAF, CFL, CHB, CHF; IBE). Two paratypes were used for DNA extraction and sequencing, with voucher numbers IBE-AN489 and IBE-AN523 respectively. Extracted specimens and DNA aliquots deposited in the IBE .

Description of the holotype: Habitus as in Fig. 1 . Body length 2.3 mm. Body shape elongate; colouration of body reddish-brownish, somewhat depigmented. Head. Eyes well developed; surface with dense punctation; suture between epistome and frons visible; antennomeres VII–XI forming a lose club, antennomeres VIII–X clearly transverse. Pronotum transverse (maximum width 0.9 mm; maximum length 0.6 mm); sides more arcuate posteriad; base straight, slightly wider than base of elytra; surface with dense, rough punctation. Elytra. Elongate, broadening posteriad in first third of length, then regularly tapering towards apex; with parasutural striae. Transverse striola on elytra broad and widely spaced. Legs. All tarsi pentamerous; protibiae simple; pro- and mesotibia slightly dilated; first three protarsomeres and first two mesotarsomeres dilated. Male genitalia ( Fig. 6 ). Aedeagus slightly curved towards ventral side; basal lamina of median lobe longer than apical part; parameres much longer than median lobe, with straight basal part, but apical third bent inwards with strong angle; apical third broader in middle region, tapering towards apex, here provided with a triangular expansion on external side; apex of parameres with three setae, without conical spine ( Fig. 14 ). Median lobe in dorsal view with broad, short apex. Endophallus with two series of sclerotised denticles, not joined in apical part, forming an apical dent.

Females similar to males except for pro- and mesotibiae, which are thinner; pro- and mesotarsi not dilated.

Etymology. The species is dedicated to our friend and colleague Hervé Brustel, from l'Ecole d'Ingénieurs de PURPAN ( France, Toulouse). The species name is a noun in the genitive case.

Remarks. According to the morphology and in particular to the aedeagus, Speonemadus brusteli sp. n. is included in the S. vandalitiae -group of Giachino & Vailati (1993), near S. orchesioides . This group is characterised by: transverse pronotum, with dense to rugose punctation; transverse striola on the elytra either fine and dense or thick and sparse; protibiae simple; sutural angle of elytra rounded in both sexes; parameres much longer than median lobe, with 3–5 apical setae and without conical spine ( Figs 13, 15–18 ); endophallus with two series of sclerotised denticles, without apical indentation. The species of the group are externally very homogeneous, and can only be separated by the study of the aedeagus ( Giachino & Vailati 1993). The general structure of the aedeagus is similar to that of S. orchesioides ( Fig. 5 ). However, the dilated apex of the parameres with a triangular expansion on the external side clearly separates S. brusteli sp. n. from this species, which has simple parameres ( Fig. 13 ). The expansion on the apex of the median lobe is also regularly arched in S. brusteli sp. n. ( Fig. 6 ), but roughly pentagonal in S. orchesioides ( Fig. 5 ). Molecular data place S. brusteli sp. n. as sister to S. maroccanus , with a considerably different aedeagus and included in the clathratus -group sensu Giachino & Vailati (1993).

Distribution ( Fig. 38 ). So far only known from the type locality in the Rif chain, Morocco.
