Abstract
We provide the first identification of male specimens of Leptobrachella korifi from its type locality in Doi Inthanon, Thailand, along with a description of its tadpole, using DNA barcoding identification. This account is based on the discovery of male and tadpole specimens of L. korifi from Inthanon National Park. Less than 0.1% of the 12S rRNA, tRNA-Val, and 16S rRNA gene sequences from the tadpoles deviate from those of the holotype of L. korifi in GenBank and the adult, thereby clarifying the identification. Adults were typically seen at night calling while resting on the dry litter of bushes surrounding streams and waterfalls, where tadpoles of this species were collected. The characters of adult males of this species are: small-sized (SVL 22.8±1.85 mm); dorsal skin smooth; venter dusted with a fine brown network; ventrolateral glands completed; distinct axillary gland, parabrachial gland, and femoral gland; toe webbing with basal and lateral fringes narrow. Tadpole’s coloration in life is beige with brown blotches on the body, tail, and fin. The Keratodont Row Formula is 1:3+3/2+2:1.

Abstract
We evaluated differences in morphology and advertisement calls of Microhyla fissipes and M. heymonsi from Nantou County, Taiwan, to better delineate the species and to improve our ability to identify them in the field. M. heymonsi in the tadpole stage is easily recognized due to the presence of an upturned funnel-like oral disc in the mouth, which has not been noted in other microhylids so far. While the two species exhibit similar call structures in temporal attributes with a series of calls each with rapidly repeating pulses, they were distinguishable with different pulse numbers per call and pulse rate. Mean call duration for M. fissipes and M. heymonsi was 0.31 ± 0.03 s (n = 97) and 0.36 ± 0.09 s (n = 153), respectively, with the calls comprising 14.3 ± 0.9 and 10.27 ± 2.09 repeating pulses with a pulse rate of 46.66 ± 2.65/s and 28.95 ± 2.91/s, respectively.

Abstract
We present the first cumulative list of freshwater diatoms from Indonesia, encompassing literature extending from 1865 until 2023. A total of 1160 names have been published. With a consideration of homotypic synonyms, the total number of different freshwater diatom taxa reported from Indonesia is over 1050. Genera with the largest number of reported species include Nitzschia (94), Cymbella sensu lato (73), Eunotia (72), Pinnularia (67), Surirella (60), and Gomphonema (48). There are two genera endemic to Indonesian freshwaters, namely Alveocymba and Celebesia, while all but one species of Tetralunata are endemic. Over 30% of the reported taxa are endemic to Indonesia. The flora of Indonesia is similar in size to that reported for all of Europe. The reported freshwater diatom flora of Indonesia, with the desmid flora, when combined, surpasses the number of all other algae reported for Indonesia.

Abstract
Sri Lanka harbors a notable diversity of freshwater crab species. 50 endemic species out of 51 described species in seven genera are found in Sri Lanka. In this study, freshwater crab distribution, densities, and hotspots were identified using geospatial techniques with a collection of data consisting of field surveys and available literature from 1960 to the present. The distribution of freshwater crabs shows distinctive patterns across the country, with spatial distribution clustered in the wet zone. Genus Oziothelphusa exhibited a widespread distribution over Sri Lanka. Density maps reveal high-density clusters in the wet zone, exhibiting a preference by crabs for wetter conditions. Ultimately, the hotspot analysis revealed that the central highlands, southwestern, and western lowlands of the wet zone of the country are the hotspots for freshwater crabs with 99% confidence. The results emphasize the importance of prioritizing conservation plans for the long-term survival of freshwater crabs in Sri Lanka.

ECOLOGICAL RISK ANALYSIS OF HARMFUL ALGAL BLOOMS (HABS) IN BIMA BAY, WEST NUSA TENGGARA, INDONESIA

Abstract
In April 2022, the occurrence of Harmful Algal Blooms (HABs) was first reported in Bima Bay, West Nusa Tenggara, resulting in a mass fish mortality event and the formation of a brown gel-like biomass that covered a significant portion of the Amahami coastal area. Here, we assess the extent of pollution and its associated ecological risk in the aquatic environment of Bima Bay. The assessment is conducted through two scenarios: 1) the vulnerability of the bay and the potential occurrence of HABs and associated pollutant load index (PLI) and water quality index (WQI); 2) the potential ecological impact of HABs related to the structure of the phytoplankton community. The PLI calculation at all stations exceeded 1, indicating an increase in environmental pollution. The pollution index (PI) at eleven stations was classified as moderately polluted, and one station was classified as lightly polluted, with a WQI of 31.67 or in the poor water quality category. Phytoplankton abundance in Bima Bay ranged from 811 – 854,724 individuals/liter. The five most dominant phytoplankton species were identified as Pseudonitzschia sp., Chaetoceros spp., Lauderia spp., Rhizosolenia spp., and Chatonella sp. The level of HAB risk in different areas of Bima Bay is based on the PI value and the proportion of the highest toxic species obtained at stations 2 and 1, with PI values of 5.83 and 5.60, and toxic proportions of 0.41 and 0.38. The distribution of HAB tends to be concentrated in the inner bay, particularly on the east and south coasts. The potential for phytoplankton blooming is relatively higher during the months of the rainy season, as indicated by the results of the chlorophyll index (satellite imagery).
