Occurrence of Small-toothed Palm Civet Arctogalidia trivirgata in Dampa Tiger Reserve, Mizoram, North-east India T. R. Shankar RAMAN1 and ZAKHUMA2 Abstract Single Small-toothed Palm Civets Arctogalidia trivirgata were seen and photographed on two consecutive nights in March 2014 in Dampa Tiger Reserve, Mizoram, India. They visited a fruiting tree used also by Masked Palm Civet Paguma larvata and Com- mon Palm Civet Paradoxurus hermaphroditus. The present note describes the observation, adding to the few recent records of A. trivirgata from North-east India. The sighting was close to the location of a 1995 sighting of Stripe-backed Weasel Mustela strigidorsa, another species rarely recorded in the region. We suggest further targeted spotlighting and camera-trap surveys for better documentation of the occurrence and distribution of small carnivores in Dampa.

Between 22 and 28 March 2014, as part of a bird survey in Dampa TR, we were camped at Tuichar Puk, a cave (puk = cave in Mizo language). The cave is located at 23°40′19.6″N, 92°25′10.7″E (WGS 84 datum, elevation 350 m measured on a perennial stream running through primary tropical wet ever- greena Garmin forests. eTrex The GPS, forest verified canopy with height altimeter) is around along 30–35 Tuichar m with Lui, evergreen and some deciduous trees, and lianas, interspersed with tall (about 40 m) emergent trees such as Dipterocarpus Fig. 1.

The Small-toothed Palm Civet, apparently ig- noring us, moved down closer on the lianas to the same level as the fruiting tree’s canopy, but did not move onto the fruiting tree. The Masked Palm Civet was also seen looking repeatedly 20 m away. No direct interaction between the two species was noticed,in the direction besides ofthe the apparent other civet avoidance that was by approximately the Small-toothed 15– Palm Civet of the fruiting tree where the Masked Palm Civet was foraging. At 21h00, when we decided to leave the animals, the Masked Palm Civet was still foraging on the fruiting tree, and the Small-toothed Palm Civet moved higher up on the liana onto the taller tree’s branches and was lost to sight. On 24 March, soon after 20h00, two civets were again observed on the same fruiting tree. One was a Common Palm Civet, foraging in the dense branches, and only its head with more distinct white facial markings and dark throat were vis- ible most of the time (Fig. 5). The second was a Small-toothed Palm Civet, also foraging on the branches with fruits. Although Fig. 3. Small-toothed Palm Civet Arctogalidia trivirgata on a liana in Fig. 5.
