Sinoelcana Gu, Tian, Wang & Yue gen. nov.
Type species.
Sinoelcana minuta Gu, Tian, Wang & Yue, sp. nov.
Etymology.
The generic name is a combination of the Greek prefix “sin-” (China) and Elcana . Gender: feminine.
Diagnosis.
Sickle-shaped ovipositor; meta-tibiae has leaf-like spurs; presence of two longitudinal veins between stem of RP and CuA+CuPaα; free CuPaα short, fused with M+CuA immediately after diverging from CuPa; CuPaα fused with M+CuA for a long distance.
Comments.
Based on the forewing venation, Sinoelcana gen. nov. can be assigned to Archelcaninae owing to its free distal parts of CuPaβ, CuPb, and AA1. The new genus is similar to Sibelcana Gorochov, 1990 and Synelcana Zessin 1988 by presence of two longitudinal veins between CuA+CuPaα and stem of RP, but it differs from Sibelcana in having a very short, free CuPaα and having CuA+CuPaα reaching the posterior wing margin, far beyond of the end of ScP; it differs from Synelcana in having a short, free CuPa, M, CuA, and CuPaα fused for a long distance, and narrow anals. Parelcana Handlirsch 1906 and Cascadelcana Fang, Muscente, Heads, Wang & Xiao, 2018 have the free CuA fused with CuPaα, which is much different from the new genus. Furthermore, the less numerous and spaced branches of the subcosta and radius, short CP, and more basal end of CuA+ CuPaα of Cascadelcana are quite different from the new genus. Sinoelcana differs from Archelcana Sharov, 1968 in that the latter only has one longitudinal vein between CuA+CuPaα and stem of RP. The type of Sinoelcana has leaf-like subapical spurs of meta-tibiae; the first three pairs are rather large. This kind of spurs is also present in another Chinese elcanid genus Jeholelcana Fang, Heads, Wang, Zhang & Wang, 2018, but differs from Hispanelcana Penalver & Grimaldi, 2010. Sinoelcana can be distinguished from Jeholelcana by its three branches of M and short CuPa.
