Type species: Teulisna ganesha Volynkin, 2023 , by present designation.

Diagnosis. Species of the subgenus ( Figs 19–91 ) are externally reminiscent of Teulisna (Tegulata) but are clearly different in their male genitalia structures ( Figs 102–144 ), which are characterised by the combination of the following features. (1) The vinculum lacks the processus intrinsicus, the medius and the medial saccate corema. The plostri with caselli are present in most species but the T. bipectinis and T. differens sp. n. species-groups. (2) The tendon is elongate and fused with its counterpart into a gelatinous string whereas other subgenera of Teulisna have a very short tendon. (3) The lamella centralis is short plate-like, with a thorn-shaped or triangular pseudoampulla in most species, situated in the middle of the valva. (4) The dorsal branch of the distal saccular process is relatively short. The female genitalia of the subgenus ( Figs 154–181 ) display no fundamental differences from other subgenera.

Etymology. The subgenus name is an aggregate of the Greek ‘ποικίλος’ meaning ‘diverse’ and the genus-group name Lithosia Fabricius, 1798 , and refers to the surprising hidden species diversity of the new subgenus. Gender is feminine.

Note. The subgenus is reviewed below in the present paper.
