Comments: Discothyrea soesilaesp. nov. is very similar to Discothyrea horni Menozzi , (1927) from Panama. The mandible of Discothyrea horni Menozzi has a dense covering of moderately long thick hairs, while the mandible of Discothyrea soesilaesp. nov. has about 30 long fine hairs. The distance between the antennae is wide in D. horni but narrow in D. soesilaesp. nov.
