The head displays relatively small eyes and mandibles resembling those of a typical female (Fig. 3). The lateral margins of the pronotum are convex and arcuate, narrowing towards the posterior angles, as typically seen in females (Fig. 3). The antennae are pectinate, similar to those of a typical male and asymmetrical between the left and right sides, with nine irregularly transformed flagellomeres (Fig. 4). The genitalia are fully developed and identical to a typical ovipositor (Fig. 5). Behavioral interactions between an intersex and a typical female To examine the b ehavioural interactions between an intersex individual and a typical female, one of each was placed in a single breeding case for observation. As a result, they exhibited only biting and aggressive behaviour, with no mating behaviour observed. Notes In P. fortunei, the prominent male sexual characteristics include pectinate antennae, relatively large eyes and a narrow pronotum (Figs 2, 3). In the observed specimen, only female sexual characteristics were displayed in all body parts, including the genitalia, except for the antennae (Figs 2, 3, 4, 5). The antennae exhibited a pectinate pattern similar to that of a male. However, the nine flagellomeres appeared as if the female flagellomeres had been transformed into a slender and elongated shape like those of a male (Fig. 4). Consequently, it was ambiguous to clearly identify this as a distinct male trait; thus, the specimen was classified as intersex. This is the first record for this family.
