Diversity of Decapod Crustaceans in Lasongko Bay, Southeast Sulawesi, Indonesia
https://doi.org/10.31396/Biodiv.Jour.2018.9.3.303.311

ABSTRACT
The aim of this study was to reveal the species diversity of Decapod Crustaceans in Lasongko Bay, Southeast Sulawesi, Indonesia. The study was conducted from April 2013 to March 2014. The sample collections were conducted on a monthly basis using gillnets at six stations. The abundance, diversity, and similarity indices of decapod species are presented spatially and temporally. Nineteen families and thirty-eight species were found in the bay, and they were dominated by the brachyuran group. The Shannon-Weiner diversity index, the evenness index, and the Simpson dominance index of the decapods spatially ranged 0.812–0.893, 0.592–0.683, and 0.215–0.313, respectively. The species similarity index ranged 0.560–0.831 spatially and 0.363–0.902 temporally. Decapods with high economic value were also discussed.

New records of Panulirus femoristriga Von Martens, 1872 (Crustacea Achelata Palinuridae) from Celebes and Seram Islands, Indonesia

ABSTRACT
The spiny lobster, Panulirus femoristriga Von Martens, 1872 (Crustacea Achelata Palinuridae), is reported for the first time from Celebes and Seram Islands, Indonesia. Three specimens were captured by hand by local fishermen on coral reefs in June 2016. Its morphological characters, habitat and distribution are reported.

On the presence of the Andaman lobster, Metanephrops andamanicus (Wood-Mason, 1891) (Crustacea Astacidea Nephropidae) in Palabuhanratu bay (S-Java, Indonesia)

ABSTRACT
The first Andaman lobster, Metanephrops andamanicus (Wood-Mason, 1891) (Crustacea Astacidea Nephropidae) record from south of Java waters, part of Indian Ocean is reported in this paper. A total of 3 specimens were collected at a fish harbor in Palabuhanratu bay in May 2015. Morphological characters are illustrated and described. This finding enhances the biodiversity lists of Indonesian crustaceans.

The mole crab Hippa marmorata (Hombron et Jacquinot, 1846) (Crustacea Anomura Hippidae): a first record from Indonesian waters

ABSTRACT
Specimens of Hippa marmorata (Hombron et Jacquinot, 1846) (Crustacea Anomura Hippidae) were collected from several coastlines of Indonesia (Sulawesi, Lombok, Tual Island, and West Papua). The specimens represent the first record of this species in Indonesia and confirm its presence in the Wallacea Line region and to its eastern fringes. Its systematic and morphological characteristics (i.e., anterior median lobe of carapace having two lobes and left antenna having two to three articles) are described. This finding provides new information on the geographical distribution of the species in Indonesian waters.

New Distribution Record of Mud Owls (Polychaeta Sternaspidae) in Mangrove Ecosystem at Lubuk Damar, Aceh Tamiang, Aceh Province, Indonesia
https://doi.org/10.31396/Biodiv.Jour.2023.14.4.623.631

ABSTRACT
The uniqueness of the Sternaspidae family was discovered in the intertidal area of the mangrove ecosystem, Lubuk Damar, Aceh Tamiang, Aceh Province. This study reports the occurrence of the mud owl Polychaete in the mangrove ecosystem as a new record in Indonesia. Samples were obtained at low tide (0–500 m) using cores with a diameter of 12.7 cm and a depth of 0–20 cm. The Sternaspidae family had morphological character differences from other Polychaeta in the form of a short and puffy body. The genus Sternaspis Otto, 1821 Lubuk Damar has two types of caudal shields, outward and deep grooves. The specimen was collected from a substrate with a percentage range of 26.67%–43.33% (sand), 46.67–56.00% (silt), and 8.00–15.33% (clay). The total 54 individual samples showed an average body length, width, and weight of 1.8–18 mm, 1–1.4 mm, 0.0009-0.1462 g, correspondingly. This research confirms that the genus Sternaspis is a cosmopolitan macrozoobenthos across the broad.

The first occurrence of Cycloachelous granulatus (H. Milne Edwards, 1834) (Decapoda Portunidae) from Klah Island, Indonesia
https://doi.org/10.31396/Biodiv.Jour.2020.11.3.793.797

ABSTRACT
This article reported the first occurrance of Cycloachelous granulatus (H. Milne Edwards, 1834) (Decapoda Portunidae) from Klah Island (close to Sabang Island), Aceh Province. Two specimens were collected in intertidal zone of Klah beach, on June 2018. Our findings contribute to Indonesian Biodiversity Database and could be used as the basis to develop faunal knowledge such as study on taxonomic, biogeographic, evolutionary or conservation.

Two morphotypes of tri-spine horseshoe crab, Tachypleus tridentatus (Leach, 1819) (Xiphosura Limulidae) in Indonesia and implications for species identification
https://doi.org/10.31396/Biodiv.Jour.2020.11.2.535.540

ABSTRACT
Of the four extant species of horseshoe crabs in the world (Xiphosura Limulidae), Indonesia have three species, i.e., Tachypleus tridentatus (Leach, 1819), T. gigas (O.F. Müller, 1785) and Carcinoscorpius rotundicauda (Latreille, 1802). The species identification based on morphology of especially the females of the two Tachypleus species can be difficult. This study aimed at evaluating morphological characters used in species determination of T. tridentatus and T. gigas. Two morphological characters for separating the two species are the number and position of immovable spines and the spinnerets on the opisthosomatic carapace. The study was conducted in Balikpapan coastal area in Indonesia. Two morphotypes of T. tridentatus were found. Of the 120 collected specimens, 13.33% had one immovable spine, while 86.67% had three immovable spines on the opisthosomatic carapace. The two morphotypes were found in both males and females. DNA barcoding of both males and females with two morphotypes confirmed that the specimens were T. tridentatus. Thus, three immovable spines at opisthosoma can still be used as a morphological characters for T. tridentatus identification, but another morphotype with only one spine is present. This makes the distinction between the females of the two Tachypleus species more difficult. However, spinnerets on the dorsal opisthosoma can still be used to separate them.

New distribution record of Elysia leucolegnote (Jensen, 1990) (Sacoglossa Plakobranchidae) in mangrove ecosystem of Biak Numfor, Papua - Indonesia
https://doi.org/10.31396/Biodiv.Jour.2020.11.1.259.262

ABSTRACT
Elysia leucolegnote (Jensen, 1990) (Sacoglossa Plakobranchidae) was firstly found in Hong Kong and described in 1989. Furthermore, in the past decade, the mangrove leaf-slug, E. leucolegnote, has been found outside Hong Kong, for example in Thailand, India, and Australia, but it is here reported for the first time in Indonesia. Details on the distribution, habitat and external morphology of E. leucolegnote in Biak Numfor, Papua, Indonesia, are here described. This species is found in mangrove ecosystems and has a similar morphological external character with previously reported which are distributed worldwide from East, South and South-east Asia to Australia. The IUCN redlist category is discussed in this paper.
