Pareumenes (Pareumenes) flavopetiolatus Giordani Soika 1979, stat. nov.

Pareumenes (Pareumenes) flavopetiolatus Giordani Soika, 1979, stat. nov. (Fig. 8) Pareumenes sansibaricus flavopetiolatus Giordani Soika, 1979: 244, ♂ — “ Niger: Dosso ” (NHMUK). Diagnosis. Placed in the subgenus Pareumenes due to the lateral carina of propodeum forming a sharp triangular lobe, the propodeal valvula forming a long lobe strongly exceeding the apex of the propodeum, and the elongate and petiolate T1 with a basal angle, it is recognized from the other species of the subgenus by the mostly impunctate and velvety body, the narrow and deep apical emargination of clypeus, the largely smooth posterior depression of propodeum, the long, robust and flattened lobes of the lateral carina of propodeum, the less elongate T1 (2.05× as long as apically wide) with a deep pit near the posterior end, the decolorate and lamellar apical margin of T1, the weakly reflexed apical margin of T2 forming a translucent lamella, and the silvery pubescence. Material examined. HOLOTYPE OF PAREUMENES SANSIBARICUS FLAVOPETIOLATUS: ♂ labeled “ NIGER / Dosso / 15.x.76 // PAR / 1 // HOLOTYPUS / Pareumenes / sansibaricus / flavopetiolatus / A. Giordani Soika [red label] // [QR code] / NHMUK015610162” (NHMUK). Distribution. Niger (Giordani Soika 1979) (Fig. 13H). Notes. Giordani Soika (1944, 1979, 1981) used a broad concept of Pareumenes sansibaricus and divided this species into six subspecies differentiated only by pattern. Photographic examination of the holotype of P. sansibaricus flavopetiolatus however showed how this taxon presents a markedly shorter and stouter T1 (about 2.05× as long as apically wide) and a translucent apical margin of T2. Given these morphological differences, the markedly different pattern and the geographical isolation of P. sansibaricus flavopetiolatus in West Africa, this taxon is elevated to species-rank.
