Subgenus Lipotactes s. str.

Type species Lipotactes alienus Brunner-Wattenwyl, 1898 (Malaysian Borneo).

NOTE. The type species of Lipotactes was described from a single female collected in northern part of Sarawak State in Malaysia (Brunner-Wattenwyl, 1898:

“Flumen Baram [Baram River] in ins. Borneo”). The male of this species from

Brunei was firstly described in details by Tan et al. (2020). Judging by the latter paper, this species has the hind femora with uniformly light proximal halves in the both sexes, and the proximedial hook of the male cercus practically as in L. alienus similajau subsp. n. ( Figs 4, 5 ); thus, if the determination of the latter authors is correct, L. alienus as well as all the other species of this subgenus are characterized by the male last tergite lacking any distinct posteromedian lobe but having a very short posteromedian notch, the male epiproct normal (not strongly reduced and without additional lateral lobules), the male paraproct with a small finger-like or roundly conical lobule at the apex, the male cercus elongately conical and with the proximedial hook having an additional tubercle on its base or very near it, as well as the male genitalia completely membranous.

The nominotypical subgenus includes the following species (in primary binomen):

type one; L. virescens Ingrisch, 1995 (Malay Peninsula); L. kabili Tan, Japir et

Chung, 2020 (Malaysian Borneo); L. (L.) sumatranus sp. n.; possibly Mortoniellus digitatus Karny, 1931 (Sulawesi) , M. digitatus var. concolor Kästner, 1933

considered by Ingrisch (1995) as a separate species (Sulawesi), M. ovatus Ingrisch,

1995 (Indonesian Borneo), M. macrognathus Ingrisch, 1995 (Malaysian Borneo)

and M. parvus Ingrisch, 1995 (Sula Islands in Indonesia).
