Species Description: Matsui M, Nishikawa K, Eto K 2014 A new burrow-utilising fanged frog from Sarawak, East Malaysia. (Anura: Dicroglossidae). Raffles Bulletin of Zoology 62: 679-687.
Compared to other Limnonectes, this species is fairly small (snout-vent length is 45mm in males and 32-43mm in females). The following combination of characteristics distinguishes L. cintalubang from other Limnonectes. Adult males have a pointed tusk and no cephalic hump. The tympanum is noticeable and the legs are fairly short. There are small pads on the digits. There is very little toe webbing. The back is quite smooth, with hints of wrinkles running horizontally across it. The back is also brown, and shows small blue spots that go down to the sides and limbs (Matsui et al. 2014).
In life, it has a chocolate brown back with small light blue spots that reach the flanks and limbs. The head has a dim orange bar behind the eyes that spans the distance between both eyes. The lower lip is brown and spotted white. The backsides of the limbs are reddish brown, whereas the sides of the limbs are speckled brown. The throat shows uneven light brown blotching. The chest and stomach are cream colored. The undersides of the hands and feet are light brown. In preservative, the back is darker in color, and the light blue spots turn white (Matsui et al. 2014).
There is little color variation between individual frogs. Body proportions were variable most likely due to ontogenetic changes. Too few specimens were found to accurately describe differences between sexes. Some smaller individuals had faint dark brown bars on the tibia and tarsus (Matsui et al. 2014).

Trends and Threats
This species is part of the Limnonectes kuhlii complex which is a clade of Bornean fanged frogs (Matsui et al. 2014).
The species name was given to allude to its burrow-utilizing lifestyle and comes from the Malay words “cintai”, meaning to love, and “lubang”, meaning a hole (Matsui et al. 2014).
This species is thought to use burrows constructed by other animals rather than constructing the burrow itself due to the lack of several morphological features associated with digging such as spade-like tubercles on the hand feet, a spade-like snout, and large forelimbs (Matsui et al. 2014).
The skin is extremely fragile and will readily rip when captured. It is possible that this is a defense mechanism to loose itself from the grasp of predators (Matsui et al. 2014).
