Abstract

The genusVietnamellaTshernova, 1972 is investigated in detail for the first time in Thailand. As a consequence, four species are recognized, namelyVietnamella maculosasp. nov.,Vietnamella thaniTshernova, 1972,Vietnamellasp. B andVietnamellasp. C. Herein, larvae and eggs ofV. maculosasp. nov.are described and reported from Chiang Rai Province. The larva ofVietnamellasp. B from Tak Province is also described, but not named due to insufficient material, and the imaginal stages and eggs ofV. thaniTshernova, 1972 are described and presented for the first time. Our morphological evidence is supported with COI data. The phylogeny showed that four different lineages of the genusVietnamellaoccur in Thailand, one of them, viz.,Vietnamellasp. C, only known from a couple of COI sequences retrieved from the Barcode of Life Data System (BOLD). Diagnoses for all known Oriental species are also presented.
