Exempel på hur man kan använda POSTPETIOLE i en mening

• Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of the abdomen has a circular or U-shaped opening (the acidopore), usually fringed with hairs.
• The body of males is depigmentated, the cuticle is thin, the petiole and postpetiole are widely connected, and degenerate mandibles, palps, and antennae are observed.
• The clypeus, legs and antennae are covered in punctulates (spots), and the postpetiole and gaster have less punctulates.
• Myrmicaria can be discerned from related ant genera by a postpetiole with a complete tergosternal fusion, a postpetiole-gaster articulation shifted ventrally on the gaster, and an antenna with seven segments.
• The head and gaster are black, and the thorax, node, and postpetiole are either red or yellowish red, while the antennae and legs are either yellow or testaceous.
• The unique shape of the promesonotum, trapezoidal in dorsal view and with well defined angles at the sides; the comparatively high and narrow petiolar node, contrasting with the broader, low and round postpetiolar node, the low position of the insertion of the postpetiole on the anterior face of first gastral segment, and the dorsal extensions of abdominal sternite 4 are unique and represent potential apomorphies of Diaphoromyrma.
• insinuator, the anteroventral edge of the postpetiole is broadly and evenly concave, without a broad median anteroventral extension.
• This species can be distinguished from all congeners by the ornate lacunose sculpturing on the head, mesosoma, petiole and postpetiole which gives the ant its specific name.
• Similar to the long clubbed hairs are short clubbed hairs present in dense amounts on the gaster, legs and postpetiole segment, and in sparser amounts on the mesosoma sides, corners of the head and on the crenulations of the facial ridges.
• Amblyoponinae is characterized by these worker characters: eyes small or absent, situated behind midlength of side of head; anterior margin of clypeus with specialized dentiform setae; promesonotal suture flexible; petiole very broadly attached to abdominal segment 3 and without a distinct posterior face; postpetiole absent; sting present and well developed.
• Pilosity pattern B is characterized by very short, fully appressed, and regular spaced setae arrayed homogeneously and equidistantly on the head, mesosoma, petiole, postpetiole and gaster.
• bessonii from Madagascar, as the two share important key characters such as the occipital collar and the elongated shapes of the head, mesonotum, scapes, legs, and postpetiole in minor workers, and the acute lateral postpetiolar process and face with obliquely longitudinal rugae in major workers.
• vulcan by slightly longer mandibles, scapes, and postpetiole, while the majors have a lower promesonotal process with a conspicuously concave transverse groove in profile view.
• kronaueri is noted for its unusual mechanism of phoretic transport - it uses its mouthparts (the mandibles) to attach itself to the waist (between the petiole and postpetiole) of medium sized ant workers of the species Eciton mexicanum.
