Fu, Siying, Jin, Zezhong & Ye, Zhen, 2025, Three new species of Velia (Cesavelia) Koçak & Kemal, 2010 (Hemiptera, Heteroptera, Veliidae) from China, ZooKeys 1254, pp. 313-329 : 313-329

Subgenus Cesavelia Koçak & Kemal, 2010

Diagnosis

(modified from Andersen 1981, and Tran et al. 2009). Antennal segment I distinctly longer than head width across eyes (except Velia anderseni Tran, Zettel & Buzzetti, 2009 , which is almost equal to head width). Mesotarsus less than 2 / 3 mesotibia length. Metatibia distinctly longer than metafemur. Metafemur of male slender or moderately incrassate (in V. anderseni ) and more heavily armed than in female on flexor side. Metatibia with scattered erect setae. In males, abdominal segment VIII relatively large, dorsal hind margin medially emarginated; proctiger plate-shaped, apically broadened; parameres prominent, strongly curved. In females, proctiger plate-shaped, covering gonocoxae and genital opening.

Key to the species of Velia ( Cesavelia)

Note. Apterous forms; updated based on the “ Key to the species of Velia ( Haldwania) in the Oriental Region ” in Tran et al. 2009). Hitherto, apterous forms of V. championi and V. steelei are still unknown ( Tran et al. 2009).
