DistributionBrazil (Pará)

Type locality: Monte Branco Plateau located in the Saracá-Taquera National Forest, Pará, Brazil (01°37’56.99”S, 56°33’29.03”W, 195 meters above sea level (m a.s.l.)  
Reproduction 
TypesHolotype: MNRJ 27562, Adult female (Figs 3–5 in Martins et al. 2023).
Paratypes (Figs 3–5). Six specimens, two females (MNRJ 27557 and 27561) and four males (MNHN-RA-2023.0001, MNRJ 27558–60). MNRJ 27557–61, unknown collector, from the type locality (01°37’S, 56°33’W); and MNHN-RA-2023.001, collected by T. Decaens and E. Lapied on March 2015, from Mitaraka (02°14’8.77”N, 54°26’57.41”W; 328 m a.s.l), French Guiana. 
DiagnosisDiagnosis: The putative autapomorphy of Siagonodon exiguum sp. nov. may be represented by lateral pointed projections on the snout or with inconspicuous lateral projection by presenting a slight concavity on the mid-rostral portion of snout (see below in comparison the opposite states for snout condition). (Martins et al. 2023)

Comment 
EtymologyThe specific epithet exiguum is a Latin word meaning little, short, scanty and/or poor. Although readers might think that the name was chosen in allusion to the small size of the species, we dedicate the species to all minorities in science including gender, race/color, ethnicity, and sexual orientation that are considerably underrepresented in the academia throughout the world, especially in higher positions. Although several worldwide initiatives have been implemented in the past few years, the scientific environment is still biased, discouraging and, sometimes noxious, largely because of persisting systemic social, economic and cultural aspects.
