Eight new taxa belonging to the tribe Landrevini are described from Laos, Malaysia and Indo-
nesia: Duolandrevus (Eulandrevus) namlik sp. nov.; D. (Duolandrevus) matang sp. nov.; D. (D.)
spinicauda gading subsp. nov.; D. (Bejorama) lambir sp. nov.; Endodrelanva aliena sp. nov.;
E. similajau sp. n.; Endolandrevus? buton sp. nov.; E.? papua sp. nov. These taxa are distin-
guished from each other and from the all previously described congeners by body colouration,
tegminal structure, peculiarities of male metanotal gland, and/or shape of some genital parts.
Additional data on distribution of some old species are also provided.
Из Лаоса, Малайзии и Индонезии описаны восемь новых таксонов трибы Landrevini:
Duolandrevus (Eulandrevus) namlik sp. nov.; D. (Duolandrevus) matang sp. nov.; D. (D.)
spinicauda gading subsp. nov.; D. (Bejorama) lambir sp. nov.; Endodrelanva aliena sp. nov.;
E. similajau sp. n.; Endolandrevus? buton sp. nov.; E.? papua sp. nov. Эти таксоны отлича-
ются один от другого и от всех ранее описанных представителей тех же родов окраской
тела, строением надкрылий, особенностями метанотальной железы самца и/или формой
некоторых генитальных частей. Приведены также новые данные по распространению
некоторых уже описанных видов.
