Paratetillabacca (Selenka, 1867) and Cinachyrellaaustraliensis (Carter, 1886) occur in a broad range of marine environments and are allegedly widely distributed species in the Indo-Pacific. We coin the term ‘moon sponges’ for these species as they are spherical in shape with numerous porocalices resembling the lunar surface. Both species have a complex taxonomic history with high synonymization, in particular by Burton (1934, 1959). An examination of the junior synonyms proposed by Burton (1934, 1959) was conducted to establish the validity of the names. More than 230 specimens from Naturalis Biodiversity Center were reviewed that belong to the genera Paratetilla and Cinachyrella from marine lakes, coral reefs, and mangroves in Indonesia. The aim of the current study was to untangle the taxonomic history, describe the collection of moon sponges from Indonesia, and develop a key. We extensively reviewed the taxonomic literature as well as holotypes of most of the species synonymized by Burton. The taxonomic history of Paratetilla spp. and Cinachyrellaaustraliensis showed some cases of misinterpreted synonyms, misidentifications, and lack of detailed descriptions for some species. The conclusion of the revision is that there are three valid species of Paratetilla (P.arcifera, P.bacca, and P.corrugata) and four valid species of Cinachyrella (C.australiensis, C.porosa, C.paterifera, and C.schulzei) in Indonesia. This is furthermore corroborated by molecular work from previous studies. ParatetillaarciferaWilson 1925 and C.porosa (Lendenfeld, 1888) are resurrected. A full review of taxonomic history is provided as well as a key for identification of moon sponges from Indonesia. All species are sympatric and we expect that there are undescribed species remaining within the Tetillidae from the Indo-Pacific. Our current review provides the framework from which to describe new species in the genera Paratetilla and Cinachyrella from the Indo-Pacific.

“…Hence, they are relatively young systems estimated to be about 6,000-12,000 years old (Dawson et al, 2009). Large numbers of marine lakes are found in the Coral Triangle in Indonesia (Becking, de Leeuw, & Vogler, 2015;Becking et al, 2011). This region is characterized by extremely high marine biodiversity (Hoeksema, 2007;Mangubhai et al, 2012).…”

Striking genetic structure among marine populations at small spatial scales is becoming evident with extensive molecular studies. Such observations suggest isolation at small scales may play an important role in forming patterns of genetic diversity within species. Isolation-by-distance, isolation-by-environment and historical priority effects are umbrella terms for a suite of processes that underlie genetic structure, but their relative importance at different spatial and temporal scales remains elusive. Here, we use marine lakes in Indonesia to assess genetic structure and assess the relative roles of the processes in shaping genetic differentiation in populations of a bivalve mussel (Brachidontes sp.). Marine lakes are landlocked waterbodies of similar age (6,000-10,000 years), but with heterogeneous environments and varying degrees of connection to the sea. Using a population genomic approach (double-digest restriction-site-associated DNA sequencing), we show strong genetic structuring across populations (range F : 0.07-0.24) and find limited gene flow through admixture plots. At large spatial scales (>1,400 km), a clear isolation-by-distance pattern was detected. At smaller spatial scales (<200 km), this pattern is maintained, but accompanied by an association of genetic divergence with degree of connection. We hypothesize that (incomplete) dispersal barriers can cause initial isolation, allowing priority effects to give the numerical advantage necessary to initiate strong genetic structure. Priority effects may be strengthened by local adaptation, which the data may corroborate by showing a high correlation between mussel genotypes and temperature. Our study indicates an often-neglected role of (evolution-mediated) priority effects in shaping population divergence.

“…Around the world, there are more than 200 marine lakes with semisubmerged karst characteristics concentrated in four main locations − Bahamas, Palau, Vietnam and Indonesia (West Papua and East Kalimantan) (Dawson et al 2009). It has been reported that Palau has 57 lakes (Colin 2009), Ha Long Bay in Vietnam has about 46 lakes (Cerano et al 2006), Derawan Islands in East Kalimantan has 14 pieces of anchihaline habitat (Becking et al 2011), and Raja Ampat in West Papua has at least 55 marine lakes (Becking et al 2009;Becking et al 2011;Becking et al 2014). Fifteen of the lakes in Raja Ampat are in Wayag and Gam, and 40 or more in Misool.…”

Purba GYS, Haryono E, Sunarto, Manan J, Rumenta L, Purwanto, Becking LE. 2018. Jellyfish Lakes at Misool Islands, Raja Ampat, West Papua, Indonesia. Biodiversitas 19: 172-182. Misool Islands, located in southern Raja Ampat in West Papua, has dozens of anchihaline lakes (marine lakes). Three of these lakes, Lenmakana, Karawapop, and Keramat, house populations of jellyfish. This study mapped and described the characteristics of the three â€˜jellyfish lakesâ€™ during field surveys in October 2015 and May 2016. The lakes ranged in area from 0.5âˆ’3.2 hectares. All three lakes harbored Mastigias papua, Lenmakana and Keramat lakes also harbored Aurelia sp., and Keramat had a third jellyfish species Cassiopea ornata. However, at Karawapop the jellyfish were not found on the water surface during the first round of field work because of effects associated with the El NiÃ±o phenomenon at that time. As a result of the El NiÃ±o effect, at Keramat, brown Mastigias became white in May 2016. The three lakes have different tidal delays (30âˆ’120 min) and dampened tidal amplitude (62%) compared to the sea. The benthos was found to be dominated by bivalves (Brachidontes sp.), algae (Cladophora sp., or Halimeda sp.) and sponges (predominantly Haliclona spp. and Tethya spp.). In addition, species of the family Synaptidae (Holothuroidea) were abundant and spread over almost all the bottom of Karawapop Lake, while tube-worms of the Polychaeta class were identified in Keramat Lake. Although these lakes are identified as a conservation area, currently there is no management activity in Lenmakana and Karawapop Lakes, despite the fact that the lakes are growing in popularity as a tourist site. Our paper provides the baseline data for future conservation efforts.
