Etymology.
The specific epithet is derived from the Greek word
mageia
, meaning ‘magic’.
Diagnosis.
As for the genus with additional characters: large and dense areolate ornamentations evenly distributed over tegmen surface, including marginal membrane but apparently smaller; RP with four terminal branches; MP forked apicad of terminal CuA; MP

with two terminal branches.

Description
. Tegmen length
7.6 mm
, broadest at apex; costal margin smoothly arched; apical margin truncate, with widely rounded anterior angle and apparently angulate posterior angle; posterior margin convex at level of termination of CuA, creating apical portion obviously widened; commissural margin carinate; basal cell absent; postcostal cell nearly as wide as the widest portion of median cell and narrower than radial cell; venation distinct; stem R almost straight, diverged from common stem R+MP at about 1/6 of tegmen length; stem ScP+R apparently longer than ScP+RA, forked at basal 0.42 of tegmen length; RA
1
simple; RP distinctly arched, with four terminal branches; stem MP sinuous, forked distinctly apicad of ScP+RA forking and slightly basad of RP forking, at basal 0.70 of tegmen length; MP 1+2 dichotomous; stem CuA closely subparallel to CuP, then bent strongly towards stem MP; CuA 1 entirely fused to stem MP and crossvein
mp-cua
replaced by free base of CuA 1
