The empoascine genus Ficiana Ghauri is reviewed based on specimens from China. One new Ficiana species, Ficiana aurantia sp. n. is described from Guangxi in south China. An identification key to all species in this genus is provided. The morphological characters of Ficiana and related genera in this tribe are discussed.

The empoascine genus Ficiana was established by
The generic characters of Ficiana need to be revised because no additional information had been added to this genus after its establishment. In this paper, a more detailed description based on specimens from China is provided. This is the first report of this genus in the Chinese fauna. In addition, a new species of Ficiana from Guangxi in south China is described, and the interpretation of morphology resemblance and reconsider the evolutionary relationship of this genus with related genera in the tribe Empoascini is discussed.
The specimens used in this study are deposited in the Entomological Museum, Northwest A&F University, Yangling, Shaanxi, China (NWAFU). Male genitalia dissections were carried out as described by
Ficiana Ghauri, 1963: 472.
Ficiana pruthii Ghauri, 1963, by original designation.
Body robust. Head including eyes broader than maximum width of pronotum in dorsal aspect (Figs
Ficiana aurantia sp. n. 8 forewing 9 hind wing 10 male genitalia, left lateral view 11 pygofer side, left lateral view 12 pygofer, dorsal view 13 anal tube and anal styli, left lateral view 14 aedeagus, left lateral view 15 aedeagus, dorsal view 16 connective 17 paramere 18 subgenital plates. Scale bars: 0.5 mm (8, 9); 0.2 mm (10); 0.1 mm (11–18).
Male abdominal apodemes developed, parallel sided (Fig.
The original illustrations of the type species made the male genital diagnosis of this genus hard to understand, especially the configuration of the aedeagus. Based on our additional new findings, it has a median sulcus of frons (Fig.

F. pruthii Ghauri |
Body length: Male 3.75–4.05 mm.
Color. General color of male orange. Crown with a brownish shallow depression beside coronal suture, sublaterally near eyes with a narrow blackish stripe on each side which is continuously extended to base of face, the stripes curved near base of vertex (Figs
Basal abdominal sternal apodemes reaching the end of segment 4 (Fig.

Unknown.
The specific epithet is an adjective derived from the Latin word “aurantium”, referring to the orange body color of the new species.
This new species differs from Ficiana pruthii Ghauri by the male pygofer not truncated caudally (Figs
China (Guangxi).
A key to the genera of the Ficiana group in the tribe as follows:
1 | Coronal suture absent | 2 |
– | Coronal suture present | 3 |
2 | Male pygofer without hook at its upper part; paramere well developed, neither concave nor provided with setae apically (spirally twisted or bifurcated apically) | Ishiharella Dworakowska |
– | Male pygofer has a well developed hook at its upper part; paramere very feebly developed and provided with setae at their concave tip | Mahmoodia Dworakowska |
3 | Anal tube with baso-ventral processes | 4 |
– | Anal tube without baso-ventral processes | 5 |
4 | Subgenital plates fused from base to subapex, lateral margins slightly convex basally and gradually narrowed apically | Ficiana Ghauri |
– | Subgenital plates fused only at their bases, lateral margins strongly convex basally and abruptly constricted near mid-length | Dialecticopteryx Kirkaldy |
5 | Aedeagal shaft with a short ventro-basal and paired slender dorso-basal processes; subgenital plates fused only at their bases | Nimabanana Dworakowska |
– | Aedeagal shaft simple, without processes; subgenital plates fused in basal 2/3–4/5 | 6 |
6 | Length of vertex, pronotum and scutellum subequal; aedeagus with preatrium; paramere with distinct preapical lobe | Daluana Ramakrishnan |
– | Length of vertex distinctly shorter than pronotum and scutellum; aedeagus without preatrium; paramere without preapical lobe | Kotwaria Dworakowska |
