Name
Aphelopus fuscoflavus Guglielmino & Olmi & Marletta & Xu, 2017 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnosis
Male with antenna filiform; head testaceous, except large brown spot on vertex; mesosoma testaceous, except area of scutum between notauli darkened, scutellum and metanotum brown, metapectal-propodeal complex black; notauli complete, posteriorly separated; basivolsella with one subdistal bristle, fused with paramere.
Description
Male. Fully winged (Fig. 1). Length 1.7 mm. Head testaceous, except large brown spot on vertex. Antenna yellow, except segments 4–10 darkened. Mesosoma testaceous, except area of scutum between notauli darkened, scutellum and metanotum brown, metapectal-propodeal complex black. Metasoma brown. Legs yellow. Antenna filiform. Antennal segments in following proportions: 3:3:4:4:5:6:6:6:6:9. Head dull, granulated. Frontal line incomplete, present in anterior half of face. Occipital carina complete. POL = 7; OL = 3; OOL = 2; OPL = 2.5; TL = 2; greatest breadth of posterior ocelli shorter than OL (2:3). Scutum, scutellum and metanotum dull, granulated. Notauli complete, posteriorly separated; minimum distance between notauli longer than greatest breadth of posterior ocelli (3:2). Metapectal-propodeal complex with dorsal surface (i.e. metapostnotum) dull, reticulate rugose; posterior surface (i.e. first abdominal tergum) reticulate rugose, with median area shiny, unsculptured. Forewing hyaline, without dark transverse bands. Basivolsella (Fig. 2) fused with paramere and with one subdistal bristle. Tibial spurs 1/1/2.
Female. Unknown.

Etymology
The name fuscoflavus derives from the Latin adjectives “fuscus” (dark) and “flavus” (yellow), because of the partly testaceous and partly brown colour.
Remarks
Because of the head testaceous, except large brown spot on vertex, the mesosoma partly testaceous and partly brown, the complete notauli, the basivolsella with one subdistal bristle, the new species is similar to Aphelopus zonalis Xu, Olmi & He, 2013, described from China, Hainan. The main difference between A. fuscoflavus and A. zonalis is centered on the structure of the basivolsella; fused with the paramere (Fig. 2) in A. fuscoflavus, not fused in A. zonalis (Fig. 3). In the key to the males of the Oriental Aphelopus species published by Xu et al. (2013)[1], the new species can be included by replacing couplets 1–4 as follows:
