Synonyms

Pashaei Rad et al. (2018) found this species in Iran on the ground in a moderate to low rainfall area. Seifert et al. (2024) report that it was found in open or partially shaded natural, rural and urban habitats with sparse soil vegetation, in semidesert, farmland with irrigation, settlements and on open river banks, and that nest entrance may be surrounded by craters of ejected soil.

Identification

Seifert et al. (2024) - Worker (Tab. 5): All shape ratios given below are, in contrast to those in Tab. 5, primary ratios without RAv and all data are given as arithmetic mean ± standard deviation. Slightly larger than T. phoenicaeum, CS 884 ± 96 µm. Head moderately elongated, CL/CW 1.077 ± 0.045. Postocular distance larger than in T. phoenicaeum, PoOc/CL 0.386 ± 0.010; excavation of hind margin of vertex smaller than in T. phoenicaeum, ExOcc 0.94 ± 0.61%. Anteromedian clypeal excision deeper and wider than in T. phoenicaeum, ExCly/CS 10.89 ± 0.66%, ExClyW 6.01 ± 0.70%. The edge of clypeal excision curves slightly down below the level of adjacent clypeal surface, thus appearing rather blunt. Sum of pubescence hairs and smaller setae protruding across the margin of clypeal excision including its dorsal edge moderate, nExCly 6.6 ± 2.6. Scape moderately long, SL/CS 0.973 ± 0.029. Minimum distance of the inner margins of antennal socket rings rather small, dAN/CS 0.296 ± 0.006. Eye moderately large, EL/CS 0.252 ± 0.011. Metanotal groove moderately deep, MGr/CS 3.58 ± 0.67%. Mesosoma longer than in T. simrothi and moderately wide, ML/CS 1.300 ± 0.038, MW/CS 0.635 ± 0.022. Second funiculus segment shorter than in T. phoenicaeum, Fu2L/CS 13.58 ± 0.43%, IFu2 1.676 ± 0.058. Pubescence, seta and pigmentation characters as in T. simrothi.

Nomenclature

The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.

  • karavaievi. Tapinoma simrothi subsp. karavaievi Emery, 1925d: 52, fig. 5 (w.q.m.) KAZAKHSTAN. Raised to species: Arnol'di & Dlussky, 1978: 547. Senior synonym of azerbeidzhanica: Dlussky, Soyunov & Zabelin, 1990: 170.
  • azerbeidzhanica. Tapinoma simrothi subsp. azerbeidzhanica Karavaiev, 1932: 248, fig. 1 (w.m.) AZERBAIJAN. Junior synonym of karavaievi: Dlussky, Soyunov & Zabelin, 1990: 170.

Type Material

Seifert et al. (2024) - This species has been described from Turkmenistan. Investigated were 4 syntype workers on the same pin labelled “Imam Baba Karavaiev”, “SYNTYPUS T.simrothi karavaievi Emery, 1925” and 6 syntype workers on two other pins with similar labelling which are deposited in MCSN Genova. As lectotype is fixed by present designation a major worker with CW 970 µm and SL 929 µm placed on the top card of the first pin. The lectotype sample is allocated with p = 0.9998 to its name-bearing cluster in a LDA considering all for species of the T. simrothi group.

Tapinoma simrothi ssp. azerbaidzhanica Karavajev, 1932 [image of type and zoogeography]

This taxon has been described from near the railroad station Ganja in Azerbaijhan (40.713°N, 46.372°E, 345 m) on the basis of males and workers. The synonymization with T. karavaievi is based on evaluation of the images of the specimen CASENT0917138 in ww.antweb.org, labelled “Gandzha Azerbeidzh. Rekat.”, “5416. Coll. Karavaievi”, “Tapinoma simrothi ssp. azerbeidzhanica Kar. typ.” [all three labels written by Karavaiev]. From Karavaievs drawings of male genitalia and the features shown by the image of the worker it is clear that the taxon belongs to the T. simrothi group. The imaged specimen is allocated in a wild-card run of an LDA with p=0.764 to T. karavaievi, with p=0.177 to T. phoenicaeum and with p=0.059 to T. insularis when considering 10 absolute measurements which could be derived from the image (CL, CW, PoOc, ExOcc, dAN, ExCly, ExClyW, Fu2L, Fu2W, SL). This morphometric classification is fully in line with occurrence probabilities expected from zoogeography.

Taxonomic Notes

Khalili-Moghadam et al. (2019) - The status of Tapinoma karavaievi requires revision. The male genitalia are extremely similar to those of Tapinoma simrothi. Perhaps T. karavaievi is the only eastern morphotype of the widespread T. simrothi. Both taxa have been recorded in Iran but only T. karavaievi probably occurs in this area.

Pashaei Rad et al. (2018) - Type location imprecise. Emery (1925) gave the type location as “Turkestan”, he also reported a specimen from Astrabad (northern Iran). The Emery specimens, e.g. as shown at CASENT0904019, are not from the original report by Mayr (1877, as “Tapinoma nigerrimum”) of collections in Turkestan, in an area most probably in (now) Uzbekistan, but from Imam-Baba, Turkmenistan.
