Antireicheia hintelmanni sp. nov.

( Figs. 6–10 , 23–29)

Type material. Holotype ( MNHN) male labelled "OKU, 2000 m / route de Banyo/ 5– 9 –XI–[19]75// lavages de/ terre// Mission Cameroun / C.N.R.S. RCP 318/ Octobre-Novembre 1975// Muséum/ Paris". Paratypes ( MNHN, PBC, PMC): 4 males, 3 females with the same data as HT; 1 female ( PBC) labelled: " Cameroon: N.- West/ prov., Mt. Oku, N 06°12./ 801´; E 010°31.837´/ 3.V.2006, 2800 m / V. Grebennikov leg."

Description. Body rusty red-brown, antennae, mouthparts and legs slightly paler ( Fig. 6 ); length 1.85– 2.00 mm (HT 1.90 mm, mean 1.92 mm, n=8, excluding single much larger 2006 female with body length 2.20 mm). Head with ocular part of genae protruded, eye remnant discernable as small, whitish unfacetted field in anterolateral margin of strongly vaulted genae; genal posterior angles shortly rounded; supraantennal plates separated from genae by deep, broad furrow; vertex with fine, regular reticulation; antennomeres 6–10 distinctly wider than long; antennal length 0.59 mm (HT). Pronotum with sides moderately rounded, not attenuated anteriorly; anterior angles sharp, distinctly protruding anterad; ratio of pronotal length to width 0.95–1.00 (HT 1.00, mean 0.97; excluding single 2006 female with ratio 1.03); ratio of pronotal width to head width 1.52–1.61 (HT 1.57, mean 1.56). Elytra slightly ovate, moderately broadened, maximum width just before middle; base slightly sloping; humeri moderately rounded; lateral channel very broad, slightly narrowed apicad; reflexed lateral margin with about 20 humero-lateral teeth, first 6–8 humeral teeth shorter and sharper, latero-apical teeth longer and more obtuse; median stria slightly and irregularly impressed in basal two thirds, other striae consisting of rows of sparse punctures; median striae moderately and equally punctured in basal two third; striae 6–7 slightly finer, latero-apical part smooth; elytral intervals flattened, third interval with 3–4 DSP; ratio of elytral length to width 1.53–1.60 (HT 1.54, mean 1.55); ratio of elytra length to pronotal length 1.90–2.05 (HT 1.92, mean 1.98); ratio of elytral width to pronotal width 1.19–1.27 (HT 1.24, mean 1.23). Aedeagus with median lobe ( Figs. 7, 8 ) 0.36 mm long (HT); parameres as in Fig. 9 . Stylomeres as in Fig. 10 .

Variability. Single female collected in 2006 at the altitude of 2800 m is lighter, larger (2.20 mm versus 1.85–2.00 mm), its pronotum is slightly narrower (ratio length to width 1.03 versus 0.97–1.00) with less protruded anterior angles.

Differential diagnosis. A. hintelmanni sp. nov. can be distinguished from A. demirei sp. nov., the second species from Mt. Oku, mainly by its smaller body (1.85–2.20 mm versus 2.70–3.00 mm); by the more protruding eyes; by the elytral margin with several marginal teeth; by the third elytral interval with (3–)4 DSP and by the different shape of the aedeagus ( Figs. 2–3 versus Figs. 7–8 ).

Etymology. Patronymic, in commemoration of the late Robert J. H. Hintelmann (Munich, Germany).
