Holotype , Glostatus perplexus : Z.A.99, Seder Berg , 500–1100m , Clanwilliam distr. C.P., humus under bushes and large stones, 1.V.1962 , N. Leleup [ NHMW ] . Diagnosis. Length 2.3–2.5 mm , 2.4 × as long as wide, colour dark brown; male(?) frons broadly flattened, with low lateral carinae from epistoma to upper level of eyes; antennal club with two clearly marked, weakly procurved, almost bisinuate sutures; setae on elytral interstriae variable in length and colour, in confused rows mixed with ground vestiture of short and broad setae; striae with deep large punctures.

Collected on several occasions from Widdringtonia (African cypress, Cupressaceae ), in the Cape region ( Wood & Bright 1992 ). It is a unique species in its variegated confused interstrial setae of variable length. However, it has split setae on the metaventrite and first abdominal ventrite as in other Diplotrichus species.
