Andrahomanus particularis ( Pic, 1932)   comb. nov.

( Figs. 19–23 View Figs , 39 View Figs , 45, 46 View Figs )

Anthicus particularis Pic, 1932: 22   .

Type locality. Mozambique, Nova-Choupanga, near Chemba.

Type material. LECTOTYPE: 1 J ( Fig. 45 View Figs ), ‘MUSÉUM PARIS ZAMBÈZE NOVA CHOUPANGA PRÈS CHEMBA P. LESNE 1929 [printed; bluish label] // 1 n JANVIER [printed] // Anthicus particularis   n sp M. Pic det [both printed and handwritten]’ ( MNHN)   . PARALECTOTYPES: 2 JJ 3 ♀♀, same data, but lacking the last label ( MNHN)   ; 1 ♀, same data, except the last label: ‘ Anthicus particularis Pic   [handwritten]’ ( MNHN)   .

Redescription (male, lectotype). Body length 3.5 mm. Head and pronotum dark brown; elytra brown black, nearly unicolour; anntennae reddish, legs reddish brown.

Head 1.2 times as long as wide, widely rounded posteriorly; posterior temporal angles rounded but distinct. Eyes small, moderately convex. Dorsal surface largely slightly glossy, densely and simply punctate; punctures large, shallow, mostly very densely spaced, nearly contiguous postero-medially, distinctly sparser anteriorly on frons. Setation short, appressed, with a few short and erect setae. Antennae rather robust, distinctly enlarged in terminal third ( Fig. 19 View Figs ); antennomere X as long as wide, antennomere XI 1.9 times as long as wide.

Pronotum robust, slightly transverse, 0.9 times as long as wide, distinctly wider than head including eyes, widely rounded to angulate anteriorly ( Fig. 46 View Figs ); pronotal disc rather convex; dorso-lateral sides of pronotum forming rounded edge, their outlines sinuous and narrowing posteriorly in dorsal view. Dorsal surface matt, very densely punctate; punctation evenly developed, punctures contiguous, similar to those on head. Setation as that on head.

Elytra 1.6 times as long as wide, conjointly rounded apically, rather convex. Surface moderately glossy, distinctly punctate; punctation in basal third distinctly finer than that on head, punctures distinctly separated. Setation pale to whitish, longer than that on head; erect setae rather distinct and numerous.

Legs simple; setation uniformly short and fine, stiff apical setae of meso- and metatibiae less conspicuous.

Abdominal sternum and tergum VII simple. Sternite VIII as in Fig. 20 View Figs ; paired prongs simple, narrow, moderately curved ventrad, rounded apically, with some longer setae subapically. Tergite VIII evenly rounded posteriorly ( Fig. 21 View Figs ). Segment IX as in Fig. 22 View Figs .

Aedeagus as in Fig. 23 View Figs ; apical portion of tegmen 0.5 times as long as basal piece, nearly evenly narrowing towards rounded apex in ventral view.

Female. Externally identical with male.

Variation. Body length (J ♀) 3.0– 3.5 mm.

Differential diagnosis. Andrahomanus particularis   is close to A. sabulicola   sp. nov. and A. opacus   sp. nov., as suggested by the similarity of the male characters. It can be distinguished from both species by unicolourous setation of elytra (not forming transverse bands), trapezoidal pronotum in dorsal view (angulate anteriorly, lateral sides less vaulted, cf. Figs. 39, 41 and 43 View Figs ) and posteriorly somewhat less bulging pronotal disc.

Distribution. Mozambique.

Remarks. PIC (1932) described Anthicus particularis   from an unstated number of specimens that were deposited in MNHN and his personal collection. Seven syntypes, belonging to the same species, were found in the general collection of MNHN, and one of them is herein designated as lectotype. No attempt was made to find any syntypes in the Pic’s collection.
