Table 1. Abbreviation (Abbr.) of morphometric characters, definition of measurements, and magnification (Mag.) used to measure each certain trait.

Abbr.	Description of the trait	Mag.
CL	Maximum median length of head capsule. The head must be carefully tilted so the maximum length is positioned in the measuring plane	×50
CWb	Maximum width of head capsule in full-face view	×50
EL	Eye length. Maximum diameter of the compound eye	×100
FL	Maximum width of frontal lobes	×100
FRS	Frontal carina distance. Distance of the frontal carinae immediately caudal of the posterior intersection points between the frontal carinae and the torular lamellae	×100
ML	Diagonal length of the alitrunk in profile. Measured in lateral view from the anteriormost point of anterior pronotal slope to the caudalmost point of the lateral metapleural lobe	×25
MW	Maximum width of pronotum	×100
NOH	Petiole node height; in a right angle from a reference line beginning at the petiolar spiracle and ending at the most caudo-dorsal point of the petiole	×100
PEL	Petiole length; horizontal distance between the petiolar spiracle and the most caudo-dorsal point of the petiole	×100
PEW	Petiole width. The maximum width of petiole in dorsal view	×100
PoOC	Postocular distance. Use a cross-scaled ocular micrometer and adjust the head to the measuring position of CL. Caudal measuring point: median occipital margin; frontal measuring point: reference line between the caudalmost border of the two compound eyes	×50
PPH	Postpetiole height. Maximum height of the postpetiole in lateral view. Measured perpendicularly to a line defined by the linear section of the segment border between dorsal and ventral petiolar sclerite	×100
PPW	Postpetiole width. Maximum width of postpetiole in dorsal view	×100
SL	Scape length. The maximum straight-line scape length excluding the articular condyle	×25
SPST	Propodeal spine length. Distance between the center of propodeal stigma and spine tip	×100
SPTI	Propodeal spine apical distance. The distance between spine tips in dorsal view; if spine tips are rounded or truncated, the centers of spine tips are taken as reference points	×100
