Worker

Chaul 2020, Figure 4. Discothyrea neotropica, worker (UFV-LABECOL-000067): A) head in full-face view; B) profile view of the body; C) dorsal view of the body; D) detail of antenna; E) mesosoma and petiole profile; F) anterior head profile view. Abbreviations: flm = frontal lamella; fl1-5 = flagellomeres 1 to 5; mssp = mesonotal spiracle; mtsp = metanotal spiracle; pe = pedicel; petsp = petiole spiracle; propsp = propodeal spiracle; sc = scape (only apical portion appearing). Scale bars are 0.1 in D, E and F and 0.2 in C. Scale bars are 0.1 mm in A, E and F and 0.2 mm in B and C.
