1A750C9F85A15D5AA49705077F16B28F.taxon	etymology	Etymology. The specific epithet “ carinolateralis ” is a compound Latin adjective, derived from “ carina ” (meaning “ keel ” or “ ridge ”) and “ lateralis ” (meaning “ lateral ”), referring to the diagnostic character of coarse longitudinal carinae on the lateroventral portion of the head capsule.

70D1A656B94C5ECF94617821032B218C.taxon	etymology	Etymology. The specific epithet “ subuncinata ” is derived from the Latin prefix “ sub - “ (meaning “ somewhat ” or “ slightly ”) combined with “ uncinatus ” (“ hooked ”), referring to the weakly upturned propodeal spines that distinguish this species. The name reflects the characteristic subtly curved propodeal spines, which is intermediate between the strongly hooked spines of some congeners (e. g., M. hamula) and the weakly hooked spines of some congeners (e. g., M. eruga from Australasia).	en	Gu, Zhuojian, Zhang, Chen, Du, Congcong, Chen, Zhilin (2025): Synopsis of the ant genus Myrmecina Curtis, 1829 from China (Hymenoptera, Formicidae, Myrmicinae), with description of eleven new species.
