Centromyrmex hamulatum

Typhloteras hamulatum Karawajew, 1925b: 129, Fig. 5, w. Current status: Centromyrmex hamulatum. Combination in Centromyrmex: Brown 1953: 8 (s/f Ponerinae). Type locality(-ies): “ Siak, Sungei Pinang (Sumatra), O. John (Nr. 355, 363 und 366), einige ww bei Capritermes, Mirotermes und Eutermes gesammelt”. Original Karawajew labels: 2 w, “ Sumatra, Siak, / Sungei Pinang, / O. John, 356, 363-6”, “ Typhloteras / hamulatum / Karavaiev, 1923. / Typus ”, “ Syntypus ww / Typhloteras / hamulatum Karaw. ”. Material: SYNTYPES, 2 w (CASENT0916831) (Box 3). Notes. There is also 1 worker (def.) with the labels “ Sumatra, Siak / Sungei Pinang / O. John, № 337-e”, “ Typhloteras hamulatum Karawajew, 1923. / Typus”, “ Syntypus / Typhloteras / hamulatum Karaw. ”, but its collection number (337-e) does not correspond with the numbers given in the original description. Beside this, there are one queen with the labels “ O. John, 411”, “ Typhloteras / hamulatum Kar. / Det. Karawajew, 25”, and one male with the labels “ O. John, 411” and “ Typhloteras / hamulatum Kar. / Det. Karawajew, 25”. Despite the queen and male not belonging to the type series, Karawajew (1926e: 419) described them for the first time, and this material has important taxonomic value.Published as part of Radchenko, Alexander G., Fisher, Brian L., Esteves, Flavia A., Martynova, Ekateryna V., Bazhenova, Tatyana N. & Lasarenko, Svetlana N., 2023, Ant type specimens (Hymenoptera, Formicidae) in the collection of Volodymyr Opanasovych Karawajew.
