Collection locality: CEIBA Biological Station , Madewini, Guyana ( CBA) and Karanambu EcoLodge, North Rupununi, Guyana, ( KBO) . GPS: 6°29 ʹ N, 58°13 ʹ W ( CBA), 3°46 ʹ N, 59°20 ʹ W ( KBO) . Collection date: 15 August 2012 ( DECBA1777 ), 7 June 2013 ( DEKBO0706 ) 9 – 10 January 2015 ( DEKBO1308 ), and 15 June 2013 ( DEKBO0514 ) . Collectors: D. Evangelista, W . Kuhn ( CBA voucher), S .

Collection/ecological information

These specimens were collected both by hand and in pitfall traps baited with beer. Specimens from the Rupununi were found entirely at sites near flood zones or bordering bodies of water. CEIBA biological station has an overall wetter climate compared to Karanambu which might be why we did not collect the CBA specimen near a body of water.

Morphological identification

This species was identified by the shape of the subgenital plate, asymmetry of the penultimate tergite and coloration of the pronotum.

Genetic information and evolutionary placement

The individual from CEIBA Biological Station (DECBA1777 – KF155133 ) was a part of the tree in Evangelista et al. (2014) however they did not find a relationship to any other taxa.

Known geographic distribution

Guyana (new record), Suriname and Brazil (Para).
