RESUMO

Four new species of genus Rhyacophila are described and illustrated from Thailand and Myanmar, Southeast Asia. Rhyacophila longicaudata sp. n. is in the R. nigrocephala Group; the very long basal segment of each inferior appendage distinguishes it from other related species. Rhyacophila aksornkoaei sp. n. and R. limsakuli sp. n. are in the R. anatina Group: they can be differentiated from other species of the group by the brush-like parameres and presence of a ventral process of the aedeagus in R. aksornkoaei sp. n., and by the rectangular apical segment of each inferior appendage and the hooked parameres in R. limsakuli sp. n.. Rhyacophila kengtungensis is in the R. yishepa Group and is characterized by the subtriangular shape of the preanal appendages in dorsal view and by the very large dorsal appendages of the phallic apparatus.

RESUMO

Two new species of caddisflies, Macrostemum nigralatum n. sp. and Anisocentropus tairomyenensis n. sp., are described and figured from lower-hill evergreen forests in southern Thailand. Wings of M. nigralatum are black, which distinguishes the new species from other related species. Anisocentropus tairomyenensis n. sp. is a member of the subgenus Anisomontropus and is characterized by the obvious basal expansion of the preanal appendages.

RESUMO

Five new species of caddisflies are described from the Upper Tenasserim Range, including Chimarra keawpradubi n. sp., Ecnomus niyomwasi n. sp., Psychomyia pinsuwanae n. sp., Leptocerus suwannarati n. sp., and Setodes lertpongsombatae n. sp., based on distinctive characters of male genitalia. Chimarra keawpradubi n. sp. differs from other Chimarra spp. in ventral aspect of inferior appendages, each of which is rectangular with a bulging process apicoventrally and with an acute apex. The basal part of each inferior appendage is square and the apical part is narrow in E. niyomwasi n. sp., differentiating it from other species in the genus. Psychomyia pinsuwanae n. sp. differs from P. amphiaraos Malicky and Chantaramongkol 1997, a closely similar species, by characters of the inferior appendages; the inner branch of each inferior appendage has a long, straight spine on its inner side. Leptocerus suwannarati n. sp. can be distinguished from other Leptocerus spp. by the processes of segment X, which are long, thin, and symmetrical. Setodes lertpongsombatae differs from other Setodes spp. in characters of segment X, which is deeply divided subapically into two very long saber-like blades in lateral view.

RESUMO

Three new species of Ceraclea (Leptoceridae) from Southeast Asia are described and illustrated: Ceraclea (Athripsodina) trisdikooni n. sp. from Myanmar, C. (A.) thongnooi n. sp. from Thailand and Myanmar and C. (A.) thongpongi n. sp. from Laos. Ceraclea trisdikooni n. sp. is distinguished from other species by its inferior appendages recurved ventrad nearly 180° apically. The apex of the basal segment of each inferior appendage is more pointed. In ventral view, each inferior appendage of the new species has an obvious basoventral lobe with numerous long setae. Ceraclea thongnooi n. sp. is distinguished from those by inferior appendages that are each shaped like a seahorse head both in lateral view and ventral view. Ceraclea thongpongi n. sp. is distinguished from other species by the rectangular preanal appendages. In dorsal view, the apical end of segment X is oval and notched apically; in ventral view, the subapicodorsal lobe of each inferior appendage is rounded and straight.

RESUMO

A new species of Limnocentropus, Limnocentropus kritsaneepaibooni n. sp. from Keng Tung Province, Shan State, Myanmar, is described and figured. Three other, previously described species of Limnocentropus are newly recorded for Myanmar, including L. apollon Malicky 1999, L. sammuanensis Malicky & Chantaramongkol 1989, and L. siribhumensis Malicky & Chantaramongkol 1989, resulting in 7 species of the family found in Myanmar.
