Fig. 5: Diversity of broadened specialized areas in Titanoptera.
From: Sound vs. light: wing-based communication in Carboniferous insects
a Theiatitan, areas between RP, M, CuA and CuP, series of relatively irregular intercalary veinlets separating large cells. b Mesotitanodes, area between branches of M with regular large cells. c Gigatitan, area between branches of M with regular large cells subdivided into irregular nets of small cells. d Clatrotitan, areas between RP, branches of M, and CuA, with highly specialized cells. Scale bars: 5 mm. e Distribution of the structures used to communicate (see Fig. 2 for more details) among the Titanoptera. Colors of veins: pink radial vein; blue median vein; green cubitus anterior vein; yellow cubitus posterior.
