Parasyscia reticulata

Identification
Chen et al. (2022) - Concolorous species, whole body yellowish brown to dark yellowish brown. Eyes reduced, ommatidial edge unclear. Petiole as long as broad in dorsal view, with almost parallel margins. Head, mesosoma petiole and abdominal segment III punctate-reticulate, sculpture of abdominal segment IV from dense punctures to sparse piligerous punctures.

This species was described based on the winged female by Emery (1923). So far, no morphological description of the worker of this species has been reported. Through careful morphological comparison, Chen et al. (2022) found that the workers of specimens (No. GXNU192821, Fig. 28) were consistent with the morphological characteristics of the queen of P. reticulata. The worker caste of P. reticulata is described for the first time here. This species is nearly identical to Parasyscia hashimotoi in worker morphology, but the petiole is more symmetrical, with the anterodorsal corner as high as the posterodorsal corner in lateral view, and in dorsal view it is subrectangular, with lateral margins parallel.
