“…This is due to the fact that mainly colour characters (of femur, lower postoculars, antenna) were used for the first classification of the species, which is clearly illustrated by the fact that species of Gymnopternus were assigned to two different groups (III, V), whereas particular Hercostomus species were even included in more than one group. During the last decade, a number of species groups in primarily Chinese Hercostomus have been erected mainly based on morphological features (Yang & Saigusa 2001;Zhang et al 2004Yang & Saigusa 2002;, 2007. Dolichopodinae represent more than 25% of all described Dolichopodidae worldwide.…”

The molecular phylogeny of the subfamily Dolichopodinae (Diptera : Dolichopodidae) is reconstructed based on 79 species of 7 dolichopodine genera as ingroup, and 10 non-dolichopodine species from different genera as outgroup. A Bayesian analysis based on a mitochondrial DNA dataset consisting of 1702 characters (COI : 810; 12S : 366; 16S : 526) was carried out. Genital and non-genital morphological characters from a hitherto unpublished data matrix (based on 57 Dolichopodidae species) were used to explain and support the lineages hypothesised by our molecular phylogenetic analysis. The monophyly of the subfamily Dolichopodinae, and of the genera Dolichopus and Gymnopternus, was confirmed. The molecular analysis yielded nine species groups in Dolichopus that were proposed in previous studies using COI and Cyt-b. No evidence was found to support a clade including Dolichopus, Ethiromyia, and Gymnopternus. The genus Hercostomus proved polyphyletic with respect to Poecilobothrus, Sybistroma, and Gymnopternus. The following lineages were represented by strongly supported clades: Hercostomus germanus species group, H. vivax species group, H. nigrilamellatus species group, H. plagiatus species group, H. longiventris species group, H. fulvicaudis species group, and Poecilobothrus, Gymnopternus, Tachytrechus and Sybistroma (including Hercostomus nanus and H. parvilamellatus). Two clades that were previously established on the basis of morphology were confirmed in our phylogenetic analysis: (i) Poecilobothrus and the flower-feeding Hercostomus germanus species group, and (ii) the H. longiventris lineage and Sybistroma. In most cases, the groups identified in the molecular analysis could be supported and explained by morphological characters. Species of the Hercostomus germanus species group, Poecilobothrus, the Hercostomus longiventris species group, and a Sybistroma subclade have a similar microhabitat affinity.

“…There were 28 known species from China before 1995, of which only 11 species are distributed in continental China (Dyte 1975;Negrobov 1991). The 225 species of Hercostomus have been added to the fauna of China since 1995 mainly based on the work of Wei (1997), Yang & Grootaert (1999), Yang & Saigusa (1999, 2000, 2001, 2002, Yang & Yang (1995), Zhang & Yang (2003), Zhang, Yang & Masunaga (2004, 2005. Up to now, 253 species of Hercostomus are known to occur in China.…”

“…Diagnosis. Using the key of Yang et al (2011), Setihercostomus scharffi seems close to S. huangi (Zhang et al, 2004) from Yunnan, but differs from that species by its entirely yellow abdominal segment 1 and partly yellow segments 2 and 3, entirely yellow hind coxa and femur, and different shape and setation of the epandrial appendages (compare Grichanov 1999, fig. 29 andZhang et al 2004, figs 3, 4;Yang et al 2011, fig.…”

Setihercostomus Zhang et Yang, 2005 is separated from the genus Hercostomus Loew, 1857, by the following combination of characters: clypeus short and narrow, not reaching lower margin of eyes, bearing one pair of strong bristles in both sexes; pteropleuron (= anepimeron) with group of fine hairs in front of posterior spiracle; male cercus large and thick, nearly as long as epandrium (Zhang & Yang 2005). Prior to this study, the genus has been recorded from the Palaearctic and Oriental regions (Zhang & Yang 2005; Yang et al. 2011), with two species from Oriental China, one known from both Palaearctic and Oriental China, one from Taiwan, and one from the Far East of Russia (Primorskii Territory). A female specimen of Setihercostomus has been recorded from Slovakia (Pollet 2009), which may be conspecific with S. setifacies (Stackelberg 1933) from the Russian Far East. Recently the senior author examined new material from Tanzania in the collection of the Natural History Museum of Denmark, Zoological Museum, University of Copenhagen (ZMUC). A male of Hercostomus scharffi Grichanov, 1999, was found, bearing characters not listed in the original description (setose clypeus and haired anepimeron), but fully corresponding with the generic diagnosis of Setihercostomus (Yang et al. 2011). Therefore, we propose a new generic combination for this species and consequently Setihercostomus is newly reported from the Afrotropical Region. Setihercostomus scharffi (Grichanov), comb. nov.
