Taxonomic notes. Pisarski (1967) described T. striativentre subsp. kabulistanicum based on the two nest samples from two different localities: 30 workers (including holotype), six gynes and one male from Cheikhabad (coll. No A 473), and three workers from Hassan Guilan (coll. No A 314). The specimens from the second locality belong to T. pisarskii sp. n., described above, and are excluded from the type series of T. kabulistanicum (see Taxonomic notes to the latter species).

T. kabulistanicum well differs from T. striativentre first of all by the sculpture of the first gastral tergite: only its basal half is densely longitudinally striato-punctated, the remaining part of tergite is smooth and shiny or at most with fine superficial microreticulation, while in the latter species whole surface of the first gastral tergite is densely longitudinally striato-punctated.

By the character of sculpture of the first gastral tergite T. kabulistanicum resembles T. pisarskii , but differs from it by the sculpture of mesosoma and waist, as well as by the sculpture on the head dorsum (see also Taxonomic notes to T. pisarskii , above).

D i s t r i b u t i o n. Afghanistan and Turkmenistan.

E c o l o g y unknown.
