Biology

Borowiec and Salata (2022) - Greece: Stigmatomma denticulatum is a thermophilous species most often collected close to streams in luminous deciduous and mixed forest. Sometimes the species was collected under stones in coniferous forest with mediterranean shrubs. In mountains, specimens were observed under limestones rocks and stones in pastures with oak shrubs. Nests were found under stones or in rock crevices on limestones walls exposed to sun. Collecting sites come from low and middle altitude (from 40 to 720 m).

Description

Worker

Borowiec and Salata (2022) - (partly after Baroni-Urbani 1978). Small to moderately large: HL: 0.746-0.921 (mean 0.833); HW: 0.627-0.809 (mean 0.714); SL: 0.397-0.543 (mean 0.481); ML: 0.94-1.24; MW: 0.40-0.51. Color. Whole body from yellow to rusty yellow. Head. Moderately elongate, 1.1-1.3 times as long as wide, widest in anterior third then softly converging posterad, occipital corners rounded, occipital margin shallowly concave. Clypeus short, transverse, with softly rounded anterior margin armed with a row of slightly angulated denticles, each denticle at apex with a minute spine. Clypeus with diffused longitudinal striation, surface microreticulate but shiny, with a pair of long erected setae in the middle and few short erected setae laterally. Mandibles long and narrow, with striated sculpture, inner margin with four large and apically bidentate teeth, two large unidentate teeth and small tooth close to apex of mandibles, a small additional tooth can be located also behind the last bidentate tooth. Head distincty microreticulate and granulate, frons often with distinct longitudinal striation, interspaces from slightly shiny to slightly dull, with long and sparse subdecumbent pubescence not covering head surface, erected setae absent, ventral side of head mostly with short subdecumbent pubescence and few erected setae. Scape very short, 0.6-0.7 times as long as width of head, stout, slightly widened from base to apex, but apically slightly constricted, its surface distinctly microreticulate and slightly dull, with short subdecumbent to suberect pubescence, ventral surface also with few erect setae. Funicular segments transverse, stout, only the first segment 1.4 times as long as wide, segments 2-5 short, slightly wider than long, the rest of funicular segments distinctly broader than six basal segments. Eyes rudimental, reduced to the one ommatidium, almost invisible. Mesosoma. Elongate, 2.3-2.5 times as long as wide, dorsally and laterally without or with rudimental microreticulation but with sparse punctuation, propodeum on sides with oblique and longitudinal striation, interspaces shiny, with short and sparse appressed to decumbent pubescence. In lateral view pronotum slightly convex, mesonotum and propodeum straight, posterior face of propodeum oblique, mesonotal suture distinct. Mesosomal dorsum lacking erected setae. Waist and gaster. Petiole in form of globular node broadly connected with gaster, surface sparsely punctate, interspaces shiny, covered with sparse and short pubescence in anterior half and longer subdecumbent to decumbent pubescence basally. Gaster longer than mesosoma, tergites with micropunctation and finely diffused microreticulation, surface shiny, covered with moderately long and moderately dense subdecumbent pubescence not covering surface and few to several longer erected setae. Legs. Stout, tibiae distinctly widened from base to apex, surface covered with moderately long and sparse subdecumbent to decumbent hairs, erected setae absent sometimes few additional suberect hairs present.

Type Material

Holotype worker from Monte Scapo (Mt. Scapo), Insel Zante (Zante Is.), Griechenland (Greece), Von Kiesenwelter (Berlin Museum für Naturkunde der Humboldt-Universität): 18992, CASENT0104566 (Yoshimura & Fisher, 2012: 3). Only one specimen from Greece is in ZMHB and it is labeled ‘‘typus.’’ Original labels on this specimen seem to have been replaced by new labels. The new label mistakenly lists the collector as ‘‘Roger, S.’’ instead of Von Kiesenwelter.
