Table 1 Dimensions of cells and cellular structures of female Megaphragma viggianii chordotonal organs (Johnston’s organ (JO) and central organ (CO)); mean ± SD (n), µm. JONL—long JO neurons, JONS—short JO neurons, CONS—short CO neurons, CONL—long CO neurons, IDS—inner dendritic segment.

From: The 3D ultrastructure of the chordotonal organs in the antenna of a microwasp remains complex although simplified
