FROGS OF COLOMBIA — COCHRAN AND GOIN

Figure 16. — Mouthparts of tadpole, Gastrotheca aureomaculata. 



A recently transformed individual is 19.4 millimeters in head and 

 body length. It is heavily pigmented but no discernible pattern can 

 be made out in the preserved specimen. The young were bright green 

 in life. 



Remarks. — In addition to the type and paratype, a dried, faded 

 female (USNM 152333) received from the National Zoological Park 

 seems to be referable to this species. According to the data that 

 accompanied the specimen, this female was collected at 10 to 15 

 miles west of Playa de Oro, Chocd, Colombia, by Marte Latham. 



Although the holotype came from the state of Huila and the para- 

 type from the state of Cauca,both are really from the same vicinity, as 

 the two localities are in the same mountain range only about 40 kilo- 

 meters apart.

Holotype. — MZUM 121024, an adult female from Moscapan, Cauca, 

 Colombia, collected by Marte Latham, April-May 1957. 



Paratypes.—MZVM 121025-30, 121031 (7 young), CJG 2305-6 

 (alive), USNM 148567-8 (alive), 152334-74 (41 young), all from Mos- 

 cop&n, Cauca, Colombia. 



Diagnosis. — A Gastrotheca without dermal appendages on heels, 

 without superciliary processes, and with the cranial derm free from 

 the cranium. An intersquamosal shelf is present but incomplete later- 

 ally, thus not forming a complete transverse shelf at the rear of the 

 head. In life the male ranges from bronzy to greenish on all exposed 

 dorsal surfaces with a dark, inky blue color on the concealed surfaces 

 of the thighs and under the arms. The female in life is a waxy green on 

 the exposed dorsal surfaces and dark inky blue on the concealed sur- 

 faces of the thighs and under the arms. Sometimes the female has the 

 top of the head change to a pale blue. In preservative adults of both 

 sexes are gun metal blue above and dirty gray below.
