Etymology This adjective [ laconicus (masculinum)] refers to Laconia, the region of the Peloponnese peninsula in which the type locality is situated.
Workers ( Figs. 5–7 View Fig View Fig View Fig )
General colouration of this species somewhat darker than in T. lichtensteini ; appendages, mesosoma, waist and basis of first gaster tergite dirty yellowish-brown to light-brown. Head dorsum and the posterior surfaces of gaster tergites darker, usually light-brown to brown. Small species ( CS 545 μm), but similar in size to its sister species. Head significantly longer than broad (CL/CWb 1.226) and with feebly convex sides. Vertexal corners rounded, posterior margin of vertex strait. Scape long (SL/ CS 0.788) with variable pubescence: adpressed (0–5°) to decumbent (10–15°) on the surface that is adjacent to head surface when the scape is directed fully caudad and subdecumbent (30°) to suberect (35–45°) on the surface that becomes external in the same scape position. Clypeus between sagittal level of frontal carinae with a number of longitudinal carinulae, interstices smooth and shiny. Eyes rather large ( EL / CS 0.246) and more approached to hind margin of vertex (PoOc/CL 0.396). Vertex with fine microreticulate sculpture that is superimposed by a number of longitudinal rugulae. Frontal carinae non-divergent. Frontal lobes widely distant ( FRS / CS 0.344). Propodeal spines very long, longer than in T. lichtensteini ( SPST / CS 0.409) and acute, in lateral view deviating from longitudinal axis of mesosoma by 20–25°. Propodeal spines in dorsal view much more divergent than in related species ( SPWI / CS 0.434), spine-tips curving inward ( SPTI / CS 0.410). Mesosoma as wide as in related species ( MW / CS 0.608). Metanotal depression well visible, moderately deep. Mesosoma with microreticulate sculpture that is
T. lichtensteini “ West Mediterranean cluster ” (blue rectangles) and T. lichtensteini type material (purple rectangle)
superimposed by a few irregular or longitudinal rugulae. Petiole and postpetiole covered by a fine reticulate microsculpture that can occasionally be superimposed by a few irregular rugulae in particular on dorsum of petiolar node. Petiole in profile with a high node and a rather straight or slightly concave anterior face; the top of the node forms a short truncate dorsum that slopes down to caudal cylinder without a distinct step.
For morphometric data of 17 nest sample means see Table 3.
Diagnosis
Pairwise analysis confirms nearly complete separation (99.4 %) between workers of T. lichtensteini (“ Western ” and “ Eastern clusters ” combined) and T. laconicus sp. n. Even drastic character reduction up to three characters (D3= − 0.0498 PoOc– 0.0541 FRS +0.0975 SPST +3.3108) yields 98.6 % classification success at individual level.
D3 scores forT: lichtensteini ð n ¼ 295 Þ: –0:6671; ½ − 4:0905; þ 1:9182 D3 scores forT: laconicussp:n: ð n ¼ 64 Þ þ 3:0748 ½þ 0:8556; þ 4:9404
The same function yields complete separation at nest sample mean level.
D3 scores forT: lichtensteini ð n ¼ 84 Þ: − 0:6762; ½ − 2:1468; þ 0:9519 D3 scores forT: laconicussp:n: ð n ¼ 17 Þ þ 3:1357 ½þ 1:9419; þ 4:2677
Application of a simple ratio ( SPST / CS) yields nonoverlapping ranges of T. lichtensteini and laconicus sp.n. at nest sample mean level (see Table 3); therefore, it can provide the most simple opportunity for separation.
