A new material on the subfamilies Pteroplistinae, Phaloriinae and Cacoplistinae from the
Indo-Malayan and Afrotropical regions of the Old World is considered. Nineteen new taxa of
these subfamilies are described: Pteroplistes malaccanus sp. nov. from Malacca, P. borneoensis
sabahi subsp. nov. from Borneo, Tramlapiola? bugiamap sp. nov. from Vietnam [Pteroplisti-
nae]; Trellius (Zatrellius) kinabalu sp. nov., T. (Z.) crocker sp. nov. and T. (Z.) tawau sp. nov.
from Borneo, T. (Neotrellius) logunovi sp. nov. and T. (N.) simulator sp. nov. from Vietnam,
Borneloria spinosa gen. et sp. nov. and B. moorei occidentalis subsp. nov. from Borneo, Pha-
loria (Papuloria) multa sp. nov. from Sulawesi and a nearest island [Phaloriinae: Phaloriini];
Subtiloria semota sp. nov. and S. succinea korup subsp. nov. from Cameroon, Schizotrypus con-
radti nigericus subsp. nov. from Nigeria, Afrophaloria malawi sp. nov. from Malawi, A. dja sp.
nov. from Cameroon [Phaloriinae: Subtiloriini]; Homoeogryllus ambo sp. nov. from Ethiopia,
H. reticulatus limbe subsp. nov. from Cameroon [Cacoplistinae: Homoeogryllini]. New data on
distribution of some other species are also given.

nae из Индо-Малайской и Афротропической областей Старого Света. Описаны девят-
надцать новых таксонов, относящихся к этим подсемействам: Pteroplistes malaccanus sp.
nov. из Малакки, P. borneoensis sabahi subsp. nov. с Борнео, Tramlapiola? bugiamap sp. nov.
из Вьетнама [Pteroplistinae]; Trellius (Zatrellius) kinabalu sp. nov., T. (Z.) crocker sp. nov. и
T. (Z.) tawau sp. nov. с Борнео, T. (Neotrellius) logunovi sp. nov. и T. (N.) simulator sp. nov. из
Вьетнама, Borneloria spinosa gen. et sp. nov. и B. moorei occidentalis subsp. nov. с Борнео,
Phaloria (Papuloria) multa sp. nov. с Сулавеси и соседнего острова [Phaloriinae: Phalori-
ini]; Subtiloria semota sp. nov. and S. succinea korup subsp. nov. из Камеруна, Schizotrypus
conradti nigericus subsp. nov. из Нигерии, Afrophaloria malawi sp. nov. из Малави, A. dja
