fuscus does not make them (Bishop 1941).īreeding phenology has not been studied in D. Unknown in this species, but the sister species D. Reproduction is likely aquatic or semi-aquatic based on adult habitat preferences and aĬonsistent lack of breeding migrations by Desmognathus species. Of the Desmognathus genus have internal fertilization via spermatophores, terrestrial eggs, Not much is known about the life history and reproduction of D. Life History, Abundance, Activity, and Special Behaviors The species was collected in shallow, active streams that were cool in temperature with Into the Piedmont region of North Carolina (Tilley et al. 2008) and Patrick County, Virginia (Mitchell 2013). The distribution of this species is concentrated within Floyd County (TilleyĮt al.

In the ventral mottling with a select few individuals with full mottled ventral side (Newmanĭesmognathus planiceps is found in southwestern Virginia within the Blue Ridge Mountains Males have a more pointed mental glad than females do. There is evidence of sexual dimorphism with males having well-developed heads (Martof and Same mottling, except it occurs posterior to the hind limbs (Newman 1955). Section, throat and gular fold region, is mottled with tan spots, while the other has the planiceps is white-tan and plain other than two sections. The sides of the tail have a row of light spots with dark borders. There isīrown and whitish-grey mottling on the sides of the body that stops abruptly on the outerĮdge of the belly. Dark-bordered light blotches line the tail region.
Other distinct markings are the yellow spots on the edge of the bandĪbove the forelimb junction with the body and the black spot on the center of the posterior
Within the band are dark spots that line up along This marking isĪ black outlined, reddish-brown band that extend from the most dorsal region of the gularįold to the posterior section of the vent. The most noticeable marking is the dorsal marking. Premaxillary fontanelle of the latter” (Newman 1955).ĭesmognathus planiceps is a brown (variation between shade of brown) colored salamander withĪ few distinct markings. These species can beĭifferentiated by the “inconspicuous inner naris, compressed tail, and absence of a marmoratus, mainly due to the flattened head. fuscus, along with a “zone of distal crown expansion” closer to However, there are minor morphologicalĭifferences between the two, including tooth morphology, in which D. Is the best way to differentiate between the two. fuscus were considered the same species and genetics Planiceps having a flattened head, dorsal makings (see next paragraph), and tan spots on the quadramaculatus but can be differentiated by D. Side with a rounded ventral side (Newman 1955).ĭesmognathus planiceps looks very similar to many species of the genus Desmognathus, The tail has a slender keel in the dorsal The relative finger lengths are 1 < 4 < 2 < 3Īnd relative toe lengths are 1 < 5 < 2 < 3 < 4. Like the body the digits have minimal webbing. The vent is “slightly raised.” The legs are stout The vertical groove extends from the sinuous groove to the junction of the jaw.ĭesmognathus planiceps has a large body that has 14 costal grooves and a range of 3 - 5 The sinuous groove extends form the superior edge of the gular fold to Two grooves have been identified on the head of the Enlarged cheeks have been described along with “pointed” mental The species has a “strongly depressed snout” with the gradient lasting from the eyes Ranges from 20 to 63 mm with some male individuals described as exceeding 120 mm in total The average snout-vent length of the species Physical Description - Desmognathus planiceps is a salamander species with a broad and flat head, stout andįlattened body, and laterally flattened tail.
