Scanning electron microscopy (SEM) micrographs of the male antenna of P. solenopsis. A Shows fifth antennal segments with different sensillum types: trichoid (TS) and chaetica subtypes 1 and 2 (ChS1 and ChS2, respectively). B A magnified view of chaetica subtype 1 (ChS1). C Distribution of different sensillum types on the fifth antennal segment: TS, ChS1, and ChS2; and a higher magnification of ChS2 at the upper left side of the micrograph. D, E The seventh flagellar segment is associated with different sensillum types: BS subtype 1, ChS subtype 1, and CaS subtype 1 with higher magnification at the upper left side of the D micrograph. F The sixth flagellar segment is associated with TS, ChS1, and CaS1 sensilla with higher magnification at the upper right side of the micrograph. G The terminal flagellar segment (eighth) associated with different sensillum types: TS, ChS subtype 1, ChS subtype 3, BS subtype 1, BS subtype 2 (higher magnification at the upper left side), and CaS subtype 2. H The tip of the terminal flagellomere associated with TS, ChS3, BS2, and CaS1 sensilla. I A magnified view of BS2 and CaS1sensilla
