Thaumaglossa demeyeri sp. n.

( Figs 1-2)

Thaumaglossa rufescens : Háva, 2003b: 210.

Type material. Holotype (male) labelled: “ Congo Elisabethville, 1957-1958, Ch. Seydel lgt.“, ( MRAC) . Paratypes: (1 male): “ Congo, Lulua , Sandoa, x.1930, G. F. Overlaet lgt.“ ( JHAC); (1 female) : “ Guinea Equatorial , Bokote, R. P. Hulstaert lgt.”, ( MRAC); (1 male): „Lualaba, Ruwe, i-iii.1960, (á la lumiere), Dr. V. Allard”, ( JHAC) .

Description. Male holotype: Body measurements (mm): TL 1.67 PL 0.40 PW 0.85 EL 1.32 EW 0.97. Strongly convex, oval, widest at humeri, orange-brown on dorsal surface; antennae and legs brown; ventral surfaces orange-brown; pubescence yellow on dorsal surface, yellow on ventral surfaces; suberect on dorsal surfaces, subrecumbent on ventral surfaces.

Head in width closely approximating length of pronotum; punctures of frons and clypeus round, shallow, about two and one-half times as large as facets of eye, nearly contiguous, becoming somewhat smaller and less dense on vertex; antennae 11-segmented, funicle sparsely clothed with fine setae, eleventh segment densely clothed with fine, erect yellow pubescence about equal in length to sixth antennal segment (fig. 1). Pronotum dark brown, with punctures of disc simple, equal in size to facets of eye, separated by one to three diameters, becoming larger and nearly contiguous toward sides, surface between them smooth and shining; pronotum covered by yellow pubescence. Elytra with punctures of disc twice as large as facets of eye, covered by yellow pubescence. Prosternum deeply, coarsely and confluently punctate on disc, without impunctate median line, becoming granulate-punctate on sides. Antennal fossae occupying entire hypomeron; fossae completely open (without margins) medially. Mesosternal disc with punctuation similar to that of prosternal disc. Abdomial sternites 2-5 with long, yellow pubescence. Male genitalia as in Fig. 2.

Female. External characters corresponding to those in male except for the form of antennal club; terminal segment small and semicircular.

Differential dignosis. The new species is visually very similar to T. holubi Háva et Kadej, 2006 , but differs from it by the unicolorous elytra (without fasciae; the elytron of T. holubi is with a transverse orange fascia), shape of terminal antennal club and male genitalia; from other Afrotropical species it differs by the colour of dorsal surfaces, shapes of antennae and male genitalia.

Remarks. The new species was erroneously cited by Háva (2003b) as T. rufescens Pic. The species T. rufescens Pic is transferred to the new genus as Volvicornis rufescens (Pic, 1927) and differs from the new species described here by the colour, male antennae and genitalia.

Etymology. The species is dedicated to my friend Dr. Marc de Meyer (MRAC).
