Abstract: The previously known species of the thread-legged bug genus Ischnobaena Stål,
1871 (Hemiptera: Heteroptera: Reduviidae: Emesinae: Metapterini), namely I.
dohrnii Stål, 1871, I. macerrima Stål, 1871 and I. staliana Wygodzinsky,
1966, are reviewed and diagnosed. Lectotypes are designated for I. dohrnii and
I. macerrima. A new species, I. castroae sp. nov., from Mindanao Island in the
Philippines is described and photographed. The new species can be distinguished
from its congeners primarily by the unicolored fore tarsus and several male
genital characters. A revised key to species of Ischnobaena is provided.
