Polyrhachis (Myrmhopla) sexspinosa Latr. var. sericea Karawajew, 1927a: 26, w, q, m (also described as a new by Karawajew, 1928: 316).
Current status: junior synonym of Polyrhachis sexspinosa (Latreille, 1802): 126, w, “Indes orientales”. Synonymy: Bolton, 1975: 12.
Type locality(-ies): “Wammar, Aru, 24.III.1913 (Nr. 2642), ww, geflüg. qq und mm in einem Nest gesammelt”.
Original Karawajew label(-s): “ Polyrhachis (Myrmhopla) / sexspinosa Latr. v. sericea / Karav . typus. / Wammar, Aru, 2597, 2642, Leg. / et det. V. Karavaev”.
Material: SYNTYPES, 6 w, 1 q (newly mounted, IN 314/6/2), 27 w (in alcohol, IN 314/ BAMS 1/Karaw11– 13).
Notes. Karawajew (1927a) provided in the original description collection number 2462 for the type series of this taxon, while in the single vial with alcohol material in NMNH NASU there are original Karawajew labels with collection numbers 2642 and 2597. We investigated all workers from this vial and confirm their conspecificity. Moreover, among the mounted specimens of var. sericea from SIZK there are syntypes series with number 2462, and one worker labeled as “Wamman, Aru. 2671. Karawajew”, “ Polyrhachis (Myrmhopla) sexspinosa Latr. v. sericea Karaw. typus ” that also does not correspond to the collection number given in the original description. We may only suppose that Karawajew did not provide all the collection numbers when describing this taxon, and we consider all the material from NMNH NASU as syntypes.
