Identification
Seifert (2023) - Worker. Numeric data given are arithmetic means based on measurement of 5 specimens (for standard deviation, minimum and maximum values see Tab. 1). Medium-sized, CS 738 µm. Head elongated, CL/CW 1.253. Genae in dorsal view nearly parallel. Median third of anterior margin of clypeus and hind margin of vertex in dorsal view straight. Frons narrower than in Formicoxenus sibiricus (FRS/CS 0.432), scape slightly shorter (SL/CS 0.712. Eye very small, EYE/CS 0.164. Dorsal profile of promesonotum and propodeum slightly convex, metanotal depression moderately deep (MGr/CS 2.95 %). Spines rather short and acute (SP/CS 0.153), their bases moderately distant (SPBA/CS 0.289). Petiole with strong anterolateral corners, in profile without peduncle and with a less broad subpetiolar lobe. Postpetiolar sternite with a welldeveloped spine. All surfaces of head, mesosoma, waist and appendages matt due to a reticulate microsculpture. Dorsal vertex strongly longitudinally carinulaterugulose. Gaster smooth and shiny but in contrast to F. sibiricus with subdecumbent to semierect setae. Head, mesosoma, waist, and gaster with long (PnHL/CS 0.128) setae, tapering apicad (Fig. 17) and round in cross-section. Color of head, mesosoma, waist and gaster homogenously yellowish brown.
As a combination of long, tapering setae, well-developed sculpture on head, mesosoma, waist and appendages and narrower frons, Formicoxenus gebaueri is unmistakable among the Palaearctic Formicoxenus species.
