Stenorhamphus barbiger ( Weirauch, 2008) , new combination

Mangabea barbiger Weirauch, 2008: 394 .

Distribution. Currently only known from the holotype collected at Parc National Ranomafana in Fianarantsoa, Madagascar, via Malaise trap at a forest edge at fairly high elevation (1,130 m, 21.2261°S, 47.3698°E), and from one male specimen collected from Province Fianarantsoa, Manombo Special Reserve camp site 32 km SSE of Farafangana via Malaise trap in lowland rainforest (36 m, 23.0218°S, 47.720°E). Deposited at the California Academy of Sciences, UCR_ENT 00005202 and UCR_ENT 00127634.

Discussion. In our analysis, Stenorhamphus orientalis and S. barbiger , new combination, are identified as sister taxa by several synapomorphies, including wing venation and head shape. Stenorhamphus barbiger differs from S. orientalis by the fascicle of stout setae on the anterior area of the gena (two pairs of setae in S. orientalis ) and the posterior pronotal lobe being slightly longer than the anterior. Stenorhamphus orientalis is found in NE Madagascar ( Villiers, 1970), while S. barbiger is found in SE Madagascar ( Weirauch, 2008). Though S. troglodytes is also found in Madagascar, it was collected along the eastern side of the country in a cave and appears to have diverged significantly from S. barbiger and S. orientalis .
