“…The use of COI data also helped in the identification of various firefly species of the genus Pteroptyx, which revealed the existence of cryptic species (Jusoh et al, 2020). This study presents the NJ, MP and BI trees of COI sequences of P. tener from Malaysia, while Luciola cruciata (Luciolinae) was chosen as an outgroup in order to construct comprehensive phylogenetic trees by referring to the previous phylogenetic studies of fireflies (Cheng, Munian, Tan, Mohd Azahari, & Shah-Fadir, 2019).…”

“…The isolation of populations in Peninsular was often hypothesized due to the Titiwangsa mountain range acting as a physical barrier that limits the movement of organisms. This isolation was observed in insect species such as Anopheles mosquitoes (Sum et al, 2014), and Coptotermes termites (Cheng et al, 2014) Nevertheless, since P. tener is highly associated with mangrove areas, it was also suggested that the distribution of this species was due to the ancient river network during Pleistocene era (Cheng et al, 2019). However, isolation over distance was not applied to the populations of P. tener in Sungai Rembau and Sungai Sepetang.…”

“…The robustness of the tree was estimated using bootstrap analysis of 1000 replications; all codons containing gaps or missing data were eliminated. The NJ, MP and BI trees were constructed with the out group of Luciola cruciata as the closest related genus to Pteroptyx species based on Cheng et al (2019).…”

The synchronous-flashing firefly, Pteroptyx tener Olivier, 1907 is a congregating firefly with high economic value for the ecotourism industry. However, the populations of P. tener are increasingly being threatened due to habitat destruction. The assessment of genetic variation within and among populations of the species from Malaysia might play a major role in conservation and management programs. Objectives of this study were to investigate the relationships among P. tener from five populations in Malaysia (Peninsular Malaysia and Borneo (Sabah) using cytochrome oxidase subunit I (COI), and to obtain its haplotype information. A total of 50 sequences of P. tener were used in the Neighbour-Joining (NJ), Maximum Parsimony (MP), and Bayesian Inference (BI) phylogenetic analyses and successfully formed several distinct clades of West and East Malaysia (East Coast and West Coast of Peninsular Malaysia) with moderately to highly supported bootstrap values and posterior probabilities. Several haplotype analysis parameters are presented; low nucleotide diversity (PiT, 0.01893), haplotype number (Hn, 19), and high haplotype diversity (Hd, 0.89469). Our findings assumed that the geographical isolation due to the inability for flying long distances without help by the wind and flooding in tidal rivers. The data presented here are important genetic information on the P. tener populations and are important for the conservation programme in Malaysia by conducting the breeding program among populations that have similar genetic information.

“…In this scenario, inland habitats represent ecological barriers and dispersal routes are consequently restricted to the coastline. However, the distribution of ancient mangroves are likely to be different compared to the present day and a recent study suggested that the dispersal of certain populations of P. tener in Peninsular Malaysia could have occurred along ancient river networks during the Pleistocene (Cheng, Munian, Sek-Aun, Faidi, & Ishak, 2019).…”

1 6 boundaries; systematics 1 7 1 8 2 ABSTRACT 1 9 Synchronous flashing fireflies of the genus Pteroptyx are ubiquitous throughout 2 0Southeast Asia, yet, knowledge on its biodiversity and evolutionary history remains 2 1 lacking. Recent studies have revealed notable population-level phylogeographic 2 2 structure within the P. tener and P. bearni groups in Malaysia, suggesting that cryptic 2 3 species may exist. Additionally, the close morphological and genetic affinity of the 2 4 recently described species P. balingiana to P. malaccae has raised questions about 2 5 its validity. In this study, we assembled the most densely sampled genetic dataset on 2 6Pteroptyx to-date to estimate a comprehensive phylogeny using mitochondrial and 2 7 nuclear DNA and subsequently implemented a suite of distance-, phylogeny-, and 2 8 coalescent-based species delimitation methods to characterize species boundaries 2 9 within the P. tener, P. bearni, and P. balingiana/P. malaccae groups. Using a total 3 0 evidence approach from multiple lines of evidence, we showed that populations of P. 3 1 tener along the west coast of Peninsular Malaysia are sufficiently divergent from 3 2 populations from the east coast and Borneo to warrant specific recognition, despite 3 3

“…Lloyd et al (1989) reported the co-occurrence of Pteroptyx malaccae and Pteroptyx valida in mangroves in Tha Chin River, a tributary of Chao Phraya River in Thailand. Although P. valida was sometimes found alone in canals further away from the river, all localities where estuarine fireflies were found were always under tidal influence (Lloyd et al, 1989) Reconstructions of the phylogenetic relationships of populations of P. tener, have in the past, consistently recovered two clades, one comprising Peninsular Malaysian samples along the west coast of Peninsular Malaysia, and Peninsular Malaysia populations from the east coast and a conspecific from Borneo, in another clade (Cheng et al, 2020;Jusoh et al, 2020). The pattern of Bornean conspecifics clustering with east coast sequences was also observed in Pteroptyx bearni, and to an extent, the clade comprising Pteroptyx malaccae and Pteroptyx balingiana (Jusoh et al, 2020).…”

Estuarine fireflies from the genusPteroptyxare widely distributed in Southeast Asia and famous for their nightly displays of bioluminescence by adult fireflies congregating or lekking on mangrove trees.Pteroptyxfireflies also offer insights into the history of the region, as their distribution in many of the isolated rivers they now inhabit are likely a product of dispersal via palaeorivers that formed in Southeast Asia during the Pleistocene. Here, we report the presence of widespread cytochrome oxidase subunit I (cox1) haplotypes among populations ofPteroptyxspp. in estuaries throughout Southeast Asia and suggest possible dispersal routes for these haplotypes vis-à-vis the Siam and Malacca River systems. Separately, reconstruction of the haplotype tree from thecox1gene indicated that the ancestors ofPteroptyx asymmetria, Pteroptyx bearni, Pteroptyx malaccae, Pteroptyx tener, andPteroptyx validaeither had a Thai, Bornean, or Peninsular Malaysian origin. Previous reconstructions of the phylogenetic and network trees ofPteroptyxsp. did not consider the presence of identical mitochondrial DNA haplotypes in their datasets, and the role palaeorivers had on their dispersal. The perspectives reported here aim to guide future taxonomic, phylogenetic and phylogeographic work onPteroptyxfireflies in Southeast Asia.
