(2023): A review of the Afrotropical Thinophilus Wahlberg, 1844 (Diptera: Dolichopodidae), with the descriptions of ten new species. European Journal of Taxonomy 878: 1-52, DOI: 10.5852/ejt.2023.878.2153, URL: http://zoobank.org/07efe4b6-4184-41c7-82a5-747bf67ba093
282DC677E93AFF9CC03FC89FFAB57AC8.taxon	discussion	Notes See diagnosis and discussion in Negrobov (1979) and Grootaert (2018). Grootaert & Meuffels (1984, 1998) distinguished three subgenera of Thinophilus in the Australasian and Oriental Regions, i. e., Thinophilus s. s., Parathinophilus Parent, 1832 and Schoenophilus Mik, 1878, and noted that the differences between them are rather poor. Negrobov (1979) and Grootaert & Meuffels (1998) described Paralleloneurum, originally described from Egypt and known also from the Oriental Region. The authors provided only one reliable character, the presence of four pairs of strong dorsocentrals on the mesonotum, to distinguish this genus from Thinophilus with five or more dorsocentrals, either nearly equal in length or greatly decreasing in length anteriorly. Later, a lot of Oriental species of Thinophilus with four pairs of dorsocentrals were described by Grootaert and his co-authors (Grootaert et al. 2015; Samoh et al. 2017, 2019; Grootaert 2018); with some of these species having apical or dorsoapical arista on postpedicel. Nevertheless, the status of Paralleloneurum Becker, 1902, Parathinophilus and Schoenophilus was not discussed. Negrobov (1979) described also Thinophilus versutus Haliday, 1851 in the genus Schoenophilus that was considered a subgenus or synonym of Thinophilus by some authors before and after 1979. He distinguished Schoenophilus from Thinophilus by the presence of only four pairs of dorsocentrals on the mesonotum and from Thinophilus and Paralleloneurum by apical or subapical arista on postpedicel. Both Paralleloneurum and Schoenophilus are regarded here as synonyms of Thinophilus (see also Discussion section). Therefore, the following new combinations are here established: Thinophilus cilifemoratus (Becker, 1902), comb. nov. and T. pygmaeus (De Meijere, 1916), comb. nov. The latter species is known only from type locality in Indonesia (Java) (De Meijere, 1916). The status of the Australian subgenus Parathinophilus needs further study. As a result, the tribe Thinophilini includes now only two genera, Thinophilus and Machaerium Haliday, 1832 with three known species in the latter genus. Incompletely described Thinophilus aquaticus Becker, 1914 known by females from Kenya (Tiwi), is not included into the key below. Thinophilus atritarsis Parent, 1929 and T. tinctus Parent, 1929 known by females from South Eastern Desert of Egypt were included into the Afrotropical Catalog (Grichanov 2018), but they are excluded here from the Region. The Palaearctic T. quadrimaculatus Becker, 1902 is also excluded from the Afrotropical fauna (see below). Thinophilus atritarsis, T. tinctus and T. quadrimaculatus are inserted into the key to West and Central Palaearctic species of Thinophilus (Grichanov 2022).	en	Grichanov, Igor Ya.

282DC677E93EFF92C057C850FAF47959.taxon	diagnosis	Diagnosis Thinophilus argyropalpis Becker, 1910 keys to T. subpalpatus sp. nov. and T. medvedevi sp. nov., differing from the latter in entirely black tarsi and black apices of tibiae; surstylus straight, slightly narrowed distally. Thinophilus subpalpatus sp. nov. and T. medvedevi sp. nov. have entirely yellow tibiae and mostly yellow tarsi; surstylus different. The male from Senegal is conspecific with the material collected from Central Asia and south-eastern Europe (see Negrobov 1979; Grichanov 2022). They have some minor differences in colouration mainly; therefore, I describe the species based on the Senegalese specimen.	en	Grichanov, Igor Ya.

282DC677E931FF93C029C821FE247DFA.taxon	discussion	Notes Types of Thinophilus calopus were collected from a sea coast; later the species was once reported from the National Park Albert (= Virunga), DR Congo, at a height about 1000 m above sea level, by Vanschuytbroeck (1951), far from the sea coast. RMCA collection contains three females identified by Vanschuytbroeck as T. calopus: two of them belong to the genus Tachytrechus and one specimen to an indeterminable species of Thinophilus. I think the species must be excluded from the fauna of the Democratic Republic of the Congo. Thinophilus annulitarsis was described from a female collected on a beach at Dar Es Salam. It has never been recorded again. A male examined from Zanzibar’s beach, close to the type locality of T. annulitarsis, is identical to the female holotype (examined) and original species description (Parent 1936) and to the detailed description of T. calopus by Loew (1862). One more male of this species was found at the site Mtwara, close to the Tanzania-Mozambique border. Therefore, I consider the two names as synonyms.	en	Grichanov, Igor Ya.

282DC677E933FF97C047C823FB1A7C39.taxon	discussion	Notes Grichanov & Mostovski (2009) examined male and female types of Thinophilus bipunctatus (NMSA) and noted that there are no principal differences from the description of T. maculatus, and the two names may be synonyms. Thinophilus bipunctatus was previously recorded from DR Congo, Namibia, and South Africa, usually from wet material (in ethanol). Unnoticed in the original description, its types have a distinct prescutellar spot in addition to six lateral spots on the mesonotum. Thinophilus maculatus was previously recorded from Gabon, Namibia and South Eastern Desert of Egypt, sometimes from females only. Both species were in fact found in the same countries as widely distributed and common T. indigenus Becker, 1902. The key characters formerly used included only colour characters, e. g., the number of dark spots on the mesonotum (Parent 1936; Grichanov 1997). The rather abundant material examined shows that this feature is variable and invisible on wet specimens. The male genitalia examined are identical in all listed specimens, corresponding with the pictures of T. indigenus from Iranian Baluchistan published by Negrobov (1978). Therefore, I consider all three names as synonyms. Thinophilus indigenus was mentioned by Rossi & Leonardi (2018: 111), as a host for the Laboulbeniales fungus Stigmatomyces ligabuei W. Rossi, 1986, found in Sierra Leone and Sudan.	en	Grichanov, Igor Ya.

282DC677E929FF8BC032CB6CFC6A7E5F.taxon	discussion	Notes Grichanov (1997) described and figured genitalia of a male from Angola under the name T. prudens, but noted that it differs from the original description of the latter species and from a male collected from Senegal in much shorter cercus, about as long as surstylus. The Angolan male belongs most probably to the new species described here as T. sigwalti sp. nov. So, Angola is excluded from the species area.	en	Grichanov, Igor Ya.

282DC677E91BFFBFC013CE37FEFB7EB0.taxon	diagnosis	Diagnosis Thinophilus fluvialis sp. nov. is close in habitus to T. manambato sp. nov., differing in fore coxa with mainly black bristles and setae; mid coxa with black bristle and setae. The last species have fore coxa with mainly white setae, with at most 2 – 3 black apical bristles; mid coxa with white setae and one black bristle. The hypopygium of T. manambato is similar to that in T. fluvialis, but the surstylus of the latter is thin (lateral view), bearing about seven short spine-like apicoventral setae; the surstylus of T. manambato is broad (lateral view), with simple ventral and apical setae. Thinophilus fluvialis keys to T. cataractae sp. nov. (see key above), differing in colour of the antenna, palp, and in morphology of hypopygium.	en	Grichanov, Igor Ya.
