Diagnosis.
The species is distinguished from congeners by the presence of apical scutellar macrosetae, the entirely gray pubescent scutellum, and two black medial macrosetae laterally on abdominal tergites 2-5.

Distribution, biodiversity hotspots, seasonal imago flight activity, and biology.
Known only from eastern South Africa, southern Mozambique, and south-eastern Zimbabwe (Fig. 51). A moderately commonly observed and collected species known from 44 specimens from 15 collecting events between 1913-1990 (Table 2). The species occurs in but is not endemic to the Maputaland-Pondoland-Albany biodiversity hotspot. Adult flies are active from spring to late summer (September-March) (Table 3). Londt (2000) reports one prey record: Diptera: Chironomidae .
Remarks.
A. unicolor was originally described from eastern-most South Africa, adjacent Mozambique, Zimbabwe, another South African locality (Nauwport interpreted to be 'Pietersburg (= Polokwane), Naawpoort’ by Londt (2000)) in north-eastern South Africa, and Namibia. The paratypes from Namibia, deposited in the NHMUK, were studied through photographs and it became clear that they are not representing the same taxon as the holotype from Ndumu Game Reserve, KwaZulu-Natal, South Africa, but belong to the widespread species A. fasciatus and are listed under that species. Therefore, this species is restricted to eastern South Africa, southern Mozambique, and south-eastern Zimbabwe.
Key to species of Anypodetus
An online, illustrated version of the below dichotomous key is available at https://keys.lucidcentral.org/keys/v4/anypodetus_dichotomous. The male terminalia illustrations included in Londt (2000) can be helpful as well but the identification below does not rely on those structures as other features can be utilized to distinguish all species.

| - | only 1 yellow or black medial macroseta laterally on abdominal T2-5 (Fig. 36) | 2 |
