Description:
This small toad has round parotoid glands, a characteristic that distinguishes it from other toad species in the region. It tends to be whitish when found in association with limestone, light tan to red around volcanic rocks, to brown above, with scattered reddish tubercles (raised bumps); the underside is creamy white. Males have dark throats and single vocal sacs. The body and head are dorsoventrally compressed, giving this toad a flattened appearance.
Adults normally 38-64 mm (1½-2½ inches) in snout-vent length. The largest Kansas specimen is female (KU 337000) from Barber County with a snout-vent length of 62.5 mm (2 7/16 inches) collected by Matthew F. Jones, Nicole D. Dzenowski, and David S. McLeod on 27 May 2014. The maximum length throughout their range is 3 inches (Conant and Collins, 1998).

Distribution:
The occurrence of this species has been documented in western Barber County and extreme southeastern Comanche County, with an isolated population in northern Clark County. An adult (51mm SVL) specimen from Morton County (KU 9100, 12 mi N Elkhart, ca Walsh's Ranch [= Wood Walsh Ranch]: 25 June 1927: Burt and Parker) was reported by Hill (1931) from the material also reported on by Taylor (1929). The Morton County specimen is supported by extant populations upstream in Cimarron County, Oklahoma, however, it is questionable because 1) it was not reported initially by Taylor (1929) and 2) has not been found in Morton County since. This specimen is in need of corroboration.

Natural History:
They search for prey at night and remain under cover during the day. Red-spotted Toads are slow-moving, more apt to walk or crawl with only occasional short hops. However, they are excellent climbers in the rocky canyons they occupy. The call is a 4 to 10-second musical trill that can be heard along intermittent canyon pools following rains in June and July. The eggs are laid in short strings or singly.

Occurrence Activity:
The blue dates denote chorusing actity. The red dates are other occurrences. The darker a date is, the greater the relative number of observations for that date.
Chorusing:

Audio recording by Keith Coleman.

Chorusing Phenology: The black outlined dots denote the Julian date (day of the year; 1 January = 1 to 31 December = 365) an observation was made. The thin red line depicts the range of dates between the beginning of the first, and end of the fourth quartile (excluding outliers; Tukey method). The thick light blue bar represents the second and third quartile (interquartile range; the middle 50% of all observations). Only one observation per Julian date is included in the graphs; so a date with multiple observations carries the same weight as a date with only one observation. The vertical bars correspond to the 12 months of the year; January through December.

Remarks:
The Red-spotted Toad was first reported in Kansas by Hill, (1931) based on the earliest existing specimen collected in 1927 (KU 9100).
The Morton County specimen (KU 9100) was collected in 1927 and all but one of the Clark County specimens were collected in 1936 and 1938 (KU 21079-94). A single specimen was collected by Jim Knight (FHSM 5250) below the dam at Clark County State Lake in 1971; however, that specimen cannot be located. The persistence of the Clark County population was verified by a specimen taken 12 May 2005 under a rock southwest of the state lake, and subsequent personal observations. The Clark County records probably represent a relictual population, as survey efforts to the south and east have produced no specimens in the intervening area through southeastern Comanche County. The Clark County population occurs in the Kiowa Shale/Cheyenne Sandstone formations there and it is interesting that they are absent from the same formation in Kiowa County.
The population that previously existed in Morton County was likely extirpated during the 1930s, however, they do persist in along the Cimarron River drainage in Oklahoma and may eventually make their way back into Kansas along that river.
Miller (1983, 1987) studied this species in western Barber County and contributed several new localities. Of particular importance in his study were his records of chorusing activity in Kansas.
The Barber and Comanche county populations occur over a vast area of relatively contiguous habitat and appear to be secure. In this area, its distribution largely coincides with the surface exposures of the Blaine Formation (Medicine Lodge Gypsum Member). Potential threats include agricultural runoff, gypsum mining, overgrazing, and the encroachment of red cedar.
The Red-spotted Toad was listed as a Kansas SINC species in 1987.
