Zigrasimecia JGD-10

(“ Z. caohuijiae _nr ”)

This worker specimen is similar to Z. caohuijiae, except for the petiolar shape which is more antero-posteriorly compressed, therefore, without the evenly round top of the node in lateral view, and by the mesosomal dorsal surface in dorsal view, which is apparently slightly more compact than in Z. caohuijiae . They share a similar head shape, to a great extent the mesosomal shape, and the petiolar shape in anterior view (petiole with a curved dorsal outline in anterior view rather than flat or bilobed). It was added to multientry key but excluded from the dichotomous; the images are by José Gómez Durán, reproduced with permission.

Examined material. One worker (ANTWEB1047077). Hukawng Valley, Kachin Province, Myanmar; Lower Cenomanian (ca.98.79 ± 0.62 Ma) [JGDC] .
