Marmosops (Marmosops) caucae

(Thomas, 1900)

VOUCHER MATERIAL: Tingana: 1 adult female ( FMNH 203324 ), 2 juvenile males ( FMNH 203326 ; MUSM 39248 ) ; see table 2 for measurements.

IDENTIFICATION: We follow Díaz-Nieto et al. (2011) and Díaz-Nieto et al. (2016) in recognizing M. caucae as a species distinct from M. impavidus . Our specimens conform in all respects to the morphology and measurements described by Díaz-Nieto et al. (2011) for M. caucae (e.g., interdigital pad 4 and hypothenar pad of hind foot in contact, two antebrachial vibrissae, palatine fenestrae present, subsquamosal foramen constricted anteroposteriorly, absence of accessory cusps on the upper canine).

REMARKS: The adult female was caught in a Victor rat trap in an agricultural field. The two adult males were caught in Victor rat traps in a renacal (flooded forest of Coussapoa trinervia ).
