Identification
A member of the Tetramorium caespitum complex. The species can be determined with a discriminant analysis of a set of morphological measurements. See Wagner et al. (2017) and https://webapp.uibk.ac.at/ecology/tetramorium/
Distribution
According to the present data (Csősz et al., 2014) T. indocile is widely distributed in steppe-like habitats from Kyrgyzstan (E 76.74◦) to Spain (W 04.06◦), but seems to be generally rare in Southern and Western Europe.
Distribution based on Regional Taxon Lists
Palaearctic Region: Armenia, France, Hungary, Kyrgyzstan (type locality), Russian Federation, Spain, Switzerland (type locality), Ukraine.

Description
Worker
Wagner et al. (2017) - Smaller than most other species of complex, CS = 717 ± 52 [575, 822] μm. Dark brown to blackish.
Head moderately elongate, CL / CW = 1.011 ± 0.014 [0.982, 1.051]. Eye medium-sized, EYE / CS = 0.174 ± 0.005 [0.162, 0.181]. Scape moderately long, SLd / CS = 0.764 ± 0.013 [0.734, 0.790]. Mesosoma moderately long and moderately wide, ML / CS = 1.155 ± 0.020 [1.107, 1.205], MW / CS = 0.637 ± 0.011 [0.609, 0.667].
Promesonotal dorsum convex, metanotal groove shallow. – Head dorsum and occiput with longitudinal costae and costulae. Postoculo-temporal area of head with rather few longitudinal costae and costulae, POTCos = 6.08 ± 1.69 [2.63, 9.75]. Mesosoma dorsum longitudinally rugulose, lateral side of propodeum with rather pronounced smooth and shiny area, Ppss = 50.0 ± 23.8 [17.6, 110.5]. – Dorsum of petiolar node often smooth, rarely feebly microreticulated. General surface appearance on average rather smooth and shiny compared with other species. – Connected stickman-like or reticulate microsculpture: small units scattered over 1st gastral tergite, MC1TG = 14.01 ± 2.44 [6.41, 19.96]. – Some workers with long c-shaped, crinkly, or sinuous hairs on ventral head posterior to buccal cavity.
Male
Wagner et al. (2017) - Paramere structure belongs to caespitum-like form: ventral paramere lobe with one or two sharp corners; without distinct emargination between paramere lobes in posterior view, paramere lobes reduced in size; in ventro-posterior view, second corner on ventral paramere lobe missing or < 87 μm apart from first. In posterior view, two sharp corners on ventral lobe.
Type Material
- Tetramorium caespitum indocile: Lectotype (designated by Csősz, Wagner, et al. 2014: 477), worker, Ssemiretschie, Kisil-Kija’ pass, Kyrgyzstan, Kusnezow, Naturhistorisches Museum, Basel.
In order to avoid any further nomenclatural problems lectotype designation for the type series is essential. We investigated 5 workers, one gyne and one male mounted on two pins. The lectotype worker by the present designation is labeled as: TYPE [—] “T. caespitum L. v indocile Sant [/] SANTSCHI det. 19 “26” [—] “Semiretschie”[/] “Kisil-Kija Pass” [/] “(Kusnezow)” [—] Sammlung Dr. F. SantschiKairouan [—] NATURHIST. MUSEUM BASEL [—] “9” [—]. The lectotype is positioned on the proximal end of the third card from the top. The lectotype worker is considered the best preserved one, a leg of a paralecto type worker is caught by its mandibles (Fig. 3A–C),but it does not hinder examination.
