Trait abbreviation: description Character definition Reference to Fig. 2
CL: Head capsule length Maximum cephalic length in median line. The head must be carefully tilted to the position with the true maximum. Fig. 2a
CW: Width of head including eyes Maximum width of the head including compound eyes. Fig. 2a
CWb: Width of head capsule Maximum width of head capsule posterior of the eyes. Fig. 2a
EL: Eye length Maximum diameter of compound eye. All structurally visible ommatidiae, pigmented or not, are included. (Not illustrated)
FRS: Frontal carinae width Distance of the frontal carinae immediately caudal of the posterior intersection points between frontal carinae and the torular lamellae. If these dorsal lamellae do not laterally surpass the frontal carinae, the deepest point of scape corner pits may be taken as reference line. These pits take up the inner corner of scape base when the scape is fully switched caudad and produce a dark triangular shadow in the lateral frontal lobes immediately posterior of the dorsal lamellae of scape joint capsule. Fig. 2b
ML: Mesosoma length Measured from caudalmost point of propodeal lobe to transition point between anterior pronotal slope and anterior pronotal shield (preferentially measured in lateral view; if the transition point is not well defined, use dorsal view and take the centre of the dark-shaded borderline between pronotal slope and pronotal shield as anterior reference point). In gynes: length from caudalmost point of propodeal lobe to the most distant point of steep anterior pronotal face. Fig. 2c
STPL: Propodeal spine tip erection Maximum distance from the center of the propodeal stigma to the margin of lateral metapleural lobe. Fig. 2d
MW: mesosoma width In workers: maximum width the pronotum excluding the pronotal spines. Fig. 2e
NOH: Maximum height of the petiolar node Measured from the uppermost point of the petiolar node perpendicular to a reference line set from the petiolar spiracle to the imaginary midpoint of the transition between dorso-caudal slope and dorsal profile of caudal cylinder of the petiole (Fig. 1D). Do not erroneously take as reference point the dorso-caudal corner of the helcium, which is sometimes visible. Nodal spines, if present, are excluded. If there is a dorsal plane of node (i.e., no convexity in frotal section), take care that left and right highest points of node are superimposing and use also position of setae bases for correct adjustment. Fig. 2d
NOL: Length of the petiolar node In lateral view NOL is measured orthogonally from the reference line fitted to the margin of caudal cylinder to the centre of petiolar spiracle. Take care that left and right profiles of caudal slope of node are superimposing and use also position of setae bases for correct adjustment. Fig. 2d
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: median head at the level of the posterior eye margin. Fig. 2a
PEH: Maximum petiole height Measured perpendicular to a ventral reference line defined as follows: the chord spanning between caudal corner of ventral petiole profile and the caudal end of the subpetiolar process. If there is a dorsal plane of node (i.e., no convexity in frontal section), take care that left and right highest points of node are superimposing and use also position of setae bases for correct adjustment. Fig. 2f
PEL: Petiolar lenght Diagonal petiolar length in lateral view; measured from the tip of subpetiolar process to dorso-caudal corner of caudal cylinder. Do not erroneously take as reference point the dorso-caudal corner of the helcium, which is sometimes visible. Fig. 2f
PEW: Petiole width Maximum width of petiole in dorsal view. Nodal spines - if any - are not considered. Fig. 2g
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 (Fig. 1F). Take care that the lowest point of left and right part of sternites are superimposing and use also position of setae bases for correct adjustment. Fig. 2f
PPL: Postpetiole length The longest anatomical line that is perpendicular to the posterior margin of the postpetiole and is between the posterior postpetiolar margin and the anterior postpetiolar margin (Fig. 4). Take care that the left and right part of frontal face of node are superimposing and use also position of setae bases for correct adjustment. Fig. 2d
PPW: Postpetiole width Postpetiole width. Maximum width of postpetiole in dorsal view. Fig. 2g
SL: Scape length Maximum length of the scape excluding the neck of articulatory condyle. Fig. 2a
SPST: Spine length Distance between the centre of propodeal stigma and spine tip. The stigma centre refers to the midpoint defined by the outer cuticular ring but not to the centre of real stigma opening that may be positioned excentrically. Fig. 2d
SPBA: Spine base width The smallest distance of the lateral margins of the spines at their base. This should be measured in dorsofrontal view, since the wider parts of the ventral propodeum do not interfere with the measurement in this position. If the lateral margins of spines diverge continuously from the tip to the base, a smallest distance at base is not defined. In this case, SPBA is measured at the level of the bottom of the interspinal meniscus. Fig. 2g
SPTI: Propodeal spine tip distance Distance of propodeal spine tips in dorsal view; if spine tips are rounded or thick take the centers of spine tips as reference points. Fig. 2g
