Genus 2. Pherotilla Brothers, 2015

Diagnosis. See the key above and Brothers (2015). This is the only genus in the subfamily Rhopalomutillinae known from the Oriental region.

Diversity and Distribution. Brothers (2015) lists five described species and mentions the existence of five undescribed species. This genus is widespread in the Afrotropical and Oriental regions. One additional species was described from China (Zhou et al. 2017).

Remarks. Brothers (2015) mentioned that this genus occurs in Thailand but did not specify which species. Okayasu et al. (2018) illustrated a female of P. striganovae from Thailand. Two females of P. striganovae were collected (along with several of their putative males) with Malaise traps in Phethaburi Province during the 2018 expedition.
