Figs 44–47
Scrapter perpunctata [sic!] Cockerell, 1933: 205–206, holotype ♀ (type locality: Knysna, South Africa) (NHML), examined.
Diagnosis
The male of S. perpunctatus is here described for the first time. The female of S. perpuncatus can be separated from that of all other species of this group by the following character combination: T3 anterior of premarginal line with a row of points (Fig. 45C–D); fine and irregular punctation on discs of T1–T4, basomedial punctation often sparse (Fig. 45C–D); propodeum with carinae, often on the entire width, not smooth (Fig. 45A–B). The male is characterized by dense (i = 0.2 d) punctation on discs of T2–T4 (Fig. 46D); dense (i = 0.2 d) punctation on disc of T2 covers at most three quarters of the tergum (Fig. 47A); relatively small stripe on T3 parallel to posterior margin without dense punctation (Fig. 46D); punctation of scutum completely dense (i <0.5 d) (Fig. 46B) and form of S7 (Fig. 47C).

Distribution
Widespread in the Greater Cape Floristic Region and known from Knysna in the SE to the Kamiesberg Mts in Namaqualand, apparently with a preference for the Fynbos biome.
Floral hosts
On Senecio sp., Felicia sp. (Asteraceae) and various unidentified yellow Asteraceae.
Seasonal activity
August–September.
Remarks
Eardley (1996) synonymised this species with S. nitidus.
A couple of female specimens that are morphologically similar to but not identical with S. perpunctatus were collected later in the year (October–November). Their identity is not clear so they are preliminarily labelled as S. cf. perpunctatus until further material from that season is available. All records of this taxon are listed below:
