Antireicheia deuvei sp. nov.

( Figs. 11–16 )

Type material. Holotype ( MNHN) male labelled "Mt Bamboutos/ 2600 m / 30.31.X.[19]75// lavages de/ terre// Mission Cameroun / C.N.R.S. RCP 318/ Octobre-Novembre 1975// Muséum/ Paris". Paratypes ( MNHN, PBC, PMC): 19 unsexed specimens with the same data as HT; 4 unsexed specimens labelled "Bamboutos/ 2600 m / 31.X. [19]75// Mission Cameroun / C.N.R.S. RCP 318/ Octobre-Novembre 1975// Muséum/ Paris".

Description. Body light rusty-brown, antennae, mouthparts and legs slightly paler ( Fig. 11 ); length 2.10– 2.30 mm (HT 2.15 mm, mean 2.19 mm, n=24). Head with ocular part of genae not protruding, eye remnant discernable as very small, whitish unfacetted field in anterolateral margin of moderately vaulted genae; genal posterior angles moderately rounded; supraantennal plates separated from genae by moderately deep and broad furrow; vertex with fine, irregular reticulation; antennomeres 6–10 slightly wider than long; antennal length 0.62 mm (HT). Pronotum with sides in anterior part very slightly (HT, some PT) to slightly (other PT) rounded, moderately attenuated anteriorly; anterior angles sharp, slightly protruding anterad; ratio of pronotal length to width 1.02–1.08 (HT 1.06, mean 1.05); ratio of pronotal width to head width 1.38–1.48 (HT 1.45, mean 1.45). Elytra almost oval, slightly broadened, maximum width just before middle; base slightly sloping; humeri broadly rounded; lateral channel broad, not narrowed apicad; reflexed lateral margin with 2(–3) humeral teeth; all striae consisting of rows of sparse, fine punctures; in apical third punctures finer; lateroapical part almost smooth; elytral intervals flattened, third interval without DSP; ratio of elytral length to width 1.66–1.79 (HT 1.71, mean 1.72); ratio of elytral length to pronotal length 2.03–2.13 (HT 2.08, mean 2.08); ratio of elytral width to pronotal width 1.21–1.32 (HT 1.28, mean 1.27). Aedeagus with median lobe ( Figs. 12, 13 ) 0.50 mm (HT); parameres as in Fig. 14 ; urite as in Fig. 15 . Stylomeres as in Fig. 16 .

Differential diagnosis. Antireicheia deuvei sp. nov. can be distinguished from A. demirei sp. nov. by the smaller body (2.10–2.30 mm versus 2.70–3.00 mm), by the elytra with less rounded humeri and by the distinctly deeper strial punctures; from A. hintelmanni sp. nov. by the non-protruding ocular part of the genae, by the elytral lateral margin without several teeth, by no DSP, and from both species by the shape of the aedeagus ( Figs. 12–13 versus Figs. 2–3 , 7–8 ). Antireicheia deuvei sp. nov. can be distinguished from A. camerounensis sp. nov. using the last couplet in the species key.

Etymology. Patronymic, in honor of Thierry Deuve (MNHN, Paris, France).
