The entry of foreign predatory fish into Indonesian open waters had the potential as a disease vector, predation, and damaging food webs that would have a systemic impact on the local ecosystem. In this study, we report the presence of the foreign predatory fish Jaguar cichlid Parachromis managuensis (Günther, 1867) from Central America in the Lingsar River, West Lombok Regency. This record is the first time for this species in Lombok, where previously this fish was found in Java. A description of the morphological characters of the captured specimens is provided in the discussion.

The genus Aristelliger comprises seven species of which six inhabit the West Indies, and one occurs in Central America and satellite islands. For the first time, the genus is reported from Cuba, and a new species (Aristelliger reyesi sp. n.) is described from that island. The new taxon has affinities with the smaller species of the genus (subgenus Aristelligella): A. expectatus, A. cochranae, and A. barbouri. It differs from them in color pattern and other morphological characters.

Representatives of some poorly known spider species collected in the rainforest litter of the Orchid Island (Taiwan) are illustrated and discussed here. A new species, Brignoliella tao sp. nov. (Fam. Tetrablemmidae), endemic to Orchid Island, is described based on both sexes. The previously unknown female of Theridiosoma triumphale Zhao & Li, 2012 (Fam. Theridiosomatidae), is described for the first time. Zoma taiwanica (Zhang, Zhu & Tso 2006) comb. nov., from the same family, is illustrated and its transfer from the genus Theridiosoma O. Pickard-Cambridge, 1879 to Zoma Saaristo, 1996 is proposed on the basis of morphological characters. Habitus and genitalia of the endemic species Gongylidioides angustus Tu & Li, 2006 (Fam. Linyphiidae) are also illustrated.

Preimaginal stages of the six species of Hydraenidae presently known from Cuba were obtained by rearing adults in the laboratory. Eggs of Hydraena perkinsi Spangler, 1980, H. decui Spangler, 1980 and H. franklyni Deler-Hernández & Delgado, 2012 are described and illustrated for the first time. The first instar larva of Gymnochthebius fossatus (LeConte, 1855) is redescribed, adding some new remarkable morphological characters including what could be the first abdominal egg-burster reported for this family. All larval instars of H. perkinsi, H. guadelupensis Orchymont, 1923 and Ochthebius attritus LeConte, 1878 are described and illustrated for the first time, with a special emphasis on their chaetotaxy. The second instar larva of G. fossatus along with first and third instar larvae of H. decui and H. franklyni are also studied for the first time. The pupal morphology and vestiture of a species belonging to the genus Hydraena are described for the first time, based on the pupa of H. perkinsi. Biological notes for several preimaginal stages of the studied species are also given.

Different Color

In 1958 Deichmann synonymized Holothuria inornata Semper, 1868 with Holothuria kefersteinii (Selenka, 1867). This nomenclature has been adopted until now. However, some specimens recently collected from the Mexican Pacific matched the original description of H. inornata Semper (1868) whereas others matched the original description by Selenka (1867). A morphological, molecular and ecological study of the specimens was conducted to confirm the identification of these specimens. The morphological characters of our specimens were compared with those contained in the original descriptions and figures of the types of both species. Besides the different color pattern of live specimens of both species, the main differences found are the presence of straight distally perforated rods in the dorsal papillae, and the presence of Holothuriophilus trapeziformis Nauck, 1880 in the cloaca of H. inornata, versus the absence of these kind of rods in the dorsal papillae, and the absence of symbionts in the cloaca in H. kefersteinii. The species identified by Deichmann (1958) as H. kefersteinii is, in fact H. inornata. Both species might have been confused because the morphology of preserved specimens is very similar and the presence of the straight rods in papillae might have been overlooked during identification. A more thorough review of the ossicles from the specimens, together with the comparison of ossicles from the type specimens, has allowed the resurrection of long-forgotten species, H. inornata

1. The main facts in Brasil's (1907) account of the intracellular schizogony inSelenidium caulleryifromProtula tubulariahave been confirmed. Early stages in the sporogony of this species are described now for the first time.2. Intracellular schizogony is described for the first time inSelenidium mesniliBrasil fromMyxicola infundibulum, and here also the early stages in sporogony are noted for the first time.3. The life histories of Caullery and Mesnil's two unnamed species ofSelenidium(now calledS. spionis(Köll.) andS. foliatumn.sp.) fromScolelepis fuliginosahave been exhaustively studied. No schizogonic phase has been observed in either. The gametocysts, here described for the first time, are found to develop fully only after escape into the sea. The gametocysts ofS. spionisare ovoid, 108μ x 60μ and contain spores with four sporozoites: those ofS. foliatumare spherical, 70μ in diameter, and their spores contain eight sporozoites.4. New or hitherto little known species ofSelenidiumare recorded fromCirratulus cirratusMüll.,Branchiomma vesiculosumMont.,Sabella pavoninaSav.,Pomatoceros triqueterL. andTerebella lepidoriaKühl, and the morphological characters of the trophozoites are described.5. A discussion follows of the value of the diagnostic characters of the genusSelenidium. It is suggested that this genus requires drastic revision and will probably have to be dismembered. Stress is laid, however, on the occurrence in all the gregarines examined, and at all the observed stages of their development, of characteristic chromatic bodies at the anterior end, structures which have hitherto escaped the notice of most observers.

Abstract Albuneid crabs are specialized and active sand-burrowing organisms. Despite their substantial diversity, their ability to avoid fishing gear leads to “under collection” and a discontinuous record of distribution. The present study documents the first distributional record of Albunea occulta Boyko, 2002 from the Bay of Bengal, eastern Indian Ocean. Albunea thurstoni Henderson, 1893 is also recorded for the first time from the area, i.e., from the Gulf of Mannar, southwestern Bay of Bengal. This study further reports variation in morphological characters, especially in the carapace grooves (CG) from previous records and across specimens from different regions. Morphometric characters were found useful in species discrimination, which is explained as well.
