A new material for the genus Afrohercostomus Grichanov, 2010 was recently collected and/or identified. The present research gives new records, including A. eronis (Curran, 1926) found for the first time in Cameroon and Ethiopia, A. golubtsovi (Grichanov, 1999) in Burundi, A. ultimus (Parent, 1935) in Uganda, and A. jani (Dyte, 1957) in Kenya. First colour photographs are provided for A. eronis and A. jani.
Key words: Afrotropical, Diptera, Dolichopodidae, Dolichopodinae, Dolichopodini, new records.
Introduction
The species of the genus Afrohercostomus were separated from the Hercostomus Loew, 1857 by Grichanov (2010), who provided a key for the Afrotropical species of Afrohercostomus. Later new records and new illustrations for some species have been published (Grichanov, 2011; Grichanov et al., 2011a, b; Grichanov & Brooks, 2017). The genus consists of 14 described and named species, which are all Afrotropical [see Grichanov (2018) for a catalogue of included species], known from Angola, Botswana, Burundi, Cameroon, Democratic Republic of the Congo, Ethiopia, Kenya, Lesotho, Madagascar (?), Malawi, Namibia, Rwanda, South Africa, Tanzania, Uganda and Zimbabwe (Fig. 1). A. argyropus (Loew, 1858) with two parapatric subspecies has the widest distribution in the region. A. a. argyropus is a southern African subspecies, whereas A. a. par (Parent, 1934) is mainly an equatorial subspecies. In this paper I provide new records for known species of the genus and first colour pictures for A. eronis (Curran, 1926) and A. jani (Dyte, 1957).
