Figure 12 Comparison of Temnothorax worker petiole characters. (A) Arrow indicates the anterodorsal tubercle; measurements depict a short petiolar peduncle; profile view of T. parralensis sp. nov (LACMENT323355). (B) Arrows indicate the transverse carina uniting the anterodorsal petiolar tubercles; dorsal view of T. parralensis sp. nov. (LACMENT323355). (C) Arrows indicate the lack of a transverse carina; dorsal view of T. quetzal sp. nov. (CASENT0614495). (D) Arrows indicate the lack of an anterodorsal petiolar tubercle and a dentiform subpetiolar process; measurements depict a moderately long petiolar peduncle; profile view of T. quetzal sp. nov. (CASENT0614495). (E) Arrow indicates a spiniform subpetiolar process; measurements depict a long petiolar peduncle; profile view of T. aztecus (CASENT0758793). (F) Measurements of NOH and NOL, used to calculate NI, depicting a long petiolar node; profile view of T. ocarinae (USNMENT00531636). Scale bars 0.2 mm. Full-size DOI: 10.7717/peerj.11514/fig-12
