Pentatrachyphloeus patruelis Voss, 1974: 417 (original description).

Pentatrachyphloeus patruelis: Borovec & Meregalli, 2013: 501 (note).

Type locality. Cape Prov . , Elands Height, 15 miles SW Mount Fletcher [ South Africa, Eastern Cape] .

Material examined. Holotype: 1 spec. (MZLU): ‘S. Afr. Cape Prov. Elands Height 15 miles SW Mount Fletcher 9.III.51 No. 217 [p] / Swedish South Africa Expedition 1950–1951 Brinck—Rudebeck [p] / Pentatrachyphloeus patruelis n. sp. E. Voss det., 1969 Holotypus [hw] / Zool. Mus. Lund Sweden Curculionidae Type No. 796: 1’ [partly p, partly hw] ( Fig. 3B ). Paratypes: 4 spec. (MZLU), labels as on holotype, except numbers from ‘796: 2’ to ‘796: 5’ (one also bearing handwritten label: ‘Museum Entomologicum, Lund. S. Afr. Cape ca 15 miles SW mt. Fletcher (Elands heights) 6000 ft. Grasmarsch’).

Remarks. Voss (1974) described Pentatrachyphloeus as a monotypic genus based on 7 specimens from Mount Fletcher in the Eastern Cape province of South Africa. The holotype is 1.97 mm long, well preserved with only the left protarsus missing. Three paratypes were remounted, two of them (male and female) after dissection. All genitalia are mounted on the labels of the respective specimens.

Pentatrachyphloeus patruelis is the type species of the genus and easily differentiated from the Palaearctic genus Trachyphloeus by the following characters: slender sulcus present between rostrum and head, elytral posthumeral calli present, protibiae without distinct spines and indentations, claws connate at base, ventrite 2 short with straight suture and plate of sternite VIII of female with posterior margin membranous and with apodeme terminated inside of plate. This exclusively South African genus now includes also P. nanus as well as 21 undescribed species, which will be described in a pending revision of the genus.
