Type species: Paratrechina pallida , by monotypy. Paraparatrechina as junior synonym of Paratrechina : Brown 1973: 183 ; Trager 1984: 58 . Status as genus. LaPolla et al. 2010 a : 128. Diagnosis. Worker (adapted from LaPolla et al. 2010 a ): Paraparatrechina workers can be identified by the following combination of characters: antenna with 12 segments; mandible with 5 or 6 teeth; maxillary palp and labial palp 6 - and 4 - segmented, respectively; erect setae on head form a distinct pattern consisting of 4 setae along posterior margin and 6 or 7 rows of paired setae from posterior margin to clypeal margin; erect setae absent on antennal scapes and legs; head excluding clypeal surface and mesonotal dorsum with dense pubescence; eyes typically well developed and positioned laterally towards the midline of head; erect mesosomal setae distinctly paired – 2 pairs on pronotum, 1 pair on mesonotum, and 1 pair on propodeum; propodeum dorsal face typically short compared to its longer posterior face; general overall mesosoma shape compact, although a few species have elongated mesosoma. Queen (adapted from Cantone 2018 ): antennae filiform with 12 segments, extending beyond occipital margin; antennal socket located near posterior edge of clypeus; forewings exhibit typology III, formica type , with a closed marginal cell; hindwings display typology II, lacking anal 2 vein; mandibles triangular and dentate; palp formula 6: 4, or in P. bufona and P. weissi , maxillary palp consists of 5 segments; mesosomal setal pattern same as in workers; metatibiae with a single spur. Male (adapted from Cantone 2017 ): antennae with 13 segments, with the scape extending beyond occipital margin; first funicular segment longer and wider than second; forewings exhibit typology III, with a closed marginal cell; hindwings correspond to typology II; mandibles edentate.
