Data from SANC accession books

AcSN 1823; Duffyoemida barkeri Martins. det. K Adlbauer, 1996. Western Cape Province, Lower Palmiet River, near Kleinmond, 18.xii. 1995, S. Neser. Adults: one found on Polygala myrtifolia ( Polygalaceae ); one emerging from twig. Larvae found burrowing in twigs of diameter c. 4-7 mm.

Remarks. – Westudiedtheholotype of Obrium rudebecki Tippmann, 1959 ( Fig. 5A) and propose that the species cannot remain in Obrium due to the presence of a distinct pre-apical cicatrix formed by a prominent transverse ridge on the scape; antennomeres VI–X nonfiliform and angulate at the apex ( Fig. 5B). In Obrium , the antennomeres are without grooves, carinae, or apical expansions ( Joly, 2010); and the genus lacks erect/sub-erect setae on the pronotum and/ or elytra. These morphological characters, together with the habitus of the pronotum and elytra, indicate the species belongs to the genus Duffyoemida Martins, 1977 , where we hereby transfer it.

We examined the holotype (♂), paratype (♀) and a series of male and female non-type specimens (SANC, det. K Adlbauer, 1996) of Duffyoemida barkeri and compared the female specimens with the holotype (♀) of Obrium rudebecki . No morphological differences were found.Therefore, we propose that Duffyoemida barkeri Martins, 1977 is a junior synonym of Duffyoemida rudebecki (Tippmann, 1959) .

Host plant: Specimens and larvae of D. rudebecki were found associated with the September Bush, Polygala myrtifolia L., an evergreen shrub occurring naturally from the Bokkeveld Mountains in the Western Cape to KwaZulu-Natal. It commonly grows on coastal dunes, rocky slopes, in forests or scrub and open grassland ( Manning & Goldblatt, 2012; Van der Walt, 2003).

Distribution. – South Africa: KwaZulu-Natal, Eastern Cape and Western Cape.
