Lipurometriocnemus amazonicus n. sp. from Manaus in the Amazon and L. biancae n. sp. from Urubici in Santa Catarina State are described and illustrated as males. Lipurometriocnemus amazonicus n. sp. can be separated from other described Lipurometriocnemus species because it lacks setae on the R1 and R4+5; has a comparatively long, low inferior volsella; comparatively few, mostly uniserial dorsocentrals; and a low AR. Lipurometriocnemus biancae n. sp. differs because it has setae on both R1 and R4+5; a distinct, rounded inferior volsella; and bi- to triserial dorsocentrals. The generic description is emended and a key to the males of all known species is provided.
