A puported javan tiger recently caught on photo in the Ujung Kulon. Just a leopard I think.

That is definitely a leopard.

Here is the evidence that it is a leopard

Abstract.

We describe a specimen of the extinct Javan tiger Panthera tigris sondaica in the Finnish Museum of Natural History LUOMUS (FMNH) in Helsinki, Finland. This specimen has not previously been described in the literature. It consists of the complete skeleton of a subadult individual collected in the nineteenth century, supposedly in Java. We confirmed the specimen's identity as a Javan tiger with a DNA analysis, an identification which was supported by a morphological examination. In addition to this Javan tiger specimen, we also subjected a few other old, wild-caught tiger specimens in the collections of the FMNH to DNA analysis. Notable results of these analyses were the identification of two twentieth-century flat skin specimens of the South China tiger P. t. amoyensis, which still survives in captivity but is extinct in the wild, and a probable Malayan tiger P. t. jacksoni skull specimen. Results of a DNA analysis of one further nineteenth-century specimen, a mounted skin of a juvenile, were inconclusive beyond establishing that it originates from the Sunda Islands; however, certain features of this specimen's pelage suggest that it, too, may be a Javan tiger.

Is the Javan tiger Panthera tigris sondaica extant? DNA analysis of a recent hair sample.

The Javan tiger Panthera tigris sondaica and the Bali tiger P. tigris balica were categorized as Extinct on the IUCN Red List in 2008 and 2013, respectively, leaving only the Sumatran subspecies P. tigris sumatrae extant in Indonesia. There have, however, been occasional, more recent reports of the Javan tiger but without conclusive evidence. Here, a potential observation in 2019 of a Javan tiger in a community plantation near the village of Cipendeuy in the forest of South Sukabumi, West Java, and a single hair found on a fence nearby, are assessed. The cytochrome b mitochondrial DNA (mtDNA) gene sequence of the putative Javan tiger hair were compared with that of a Javan tiger specimen in Museum Zoologicum Bogoriense, collected in 1930; hair samples of several tiger subspecies and the Javan leopard Panthera pardus melas were used as controls. The results showed that the genetic distances (d) of the putative Javan tiger hair with the Sumatran, Bengal P. tigris tigris and Amur P. tigris altaica tigers and the Javan leopard are 0.074 ± SE 0.009, 0.071 ± SE 0.009, 0.072 ± SE 0.009 and 0.088 ± SE 0.010, respectively, whereas the genetic distance of the putative Javan tiger hair with the Javan tiger museum specimen is 0.040 ± SE 0.006. In addition, phylogenetic trees showed that the putative Javan tiger hair sample belongs to the same group as the museum specimen of the Javan tiger, but is differentiated from other tiger subspecies and the Javan leopard. Whether the Javan tiger still occurs in the wild needs to be confirmed with further genetic and field studies.

No Reliable Evidence Supports the Presence of Javan Tigers - Data Issues Related to the DNA Analysis of a Recent Hair Sample.

A paper recently published in Oryx by Wirdateti et al. (2024) suggests that the extinct Javan tiger may still survive on the Island of Java, Indonesia, based on mtDNA analysis of a single hair collected from a claimed tiger encounter site. After carefully re-analyzing the data presented in Wirdateti et al. (2024), we conclude that there is little support for the authors’ statements. Importantly, the sequences of the putative tiger hair and museum Javan tiger specimens generated by the authors are not from tiger cytoplasmic mitochondrial DNA but more likely the nuclear copies of mitochondrial DNA. In addition, the high mismatches found between the two “Javan tiger” sequences generated by the authors is unusual for homologous sequences that are both from tigers and hence indicative of data unreliability. Yet, too few details regarding the quality control were provided in Wirdateti et al. (2024) to rule out the possibility of contamination introduced during the data production process. In conclusion, it is inappropriate to use these unreliable sequences presented in Wirdateti et al. (2024) to infer the existence of the Javan tiger.
