Spea bombifrons (Cope, 1863) , Great Plains Spadefoot

New record. First record for Ojinaga Municipality: found calling in cattle tank along E–W road across northern edge of Llano Amapolas (29.02702° N, 104.16879° W; WGS84), 16 May 2016, Sean P. Graham, Mark W. Herr, and Tomas Hernandez (SRSU-D 37).

Remarks. A chorus of about 5–7 calling males heard; 1 was recorded calling and photographed. There are only a handful of records for this explosively-breeding frog from Chihuahua; this record extends the species’ range in the state some 200 km from the nearest populations to the west (Municipality of Chihuahua) and southwest (Municipality of Camargo). There are also closer records to the north from Presidio and Brewster County, Texas ( Dixon 2013, Graham and Kelehear 2014).
