“…Up to this date, the family was represented by a single species, Lourinia armata (Claus, 1866); although two species ( Lourinia aculeata (Thompson I.C. & Scott A., 1903) and Lourinia nicobarica (Sewell, 1940)) and three subspecies ( Lourinia armata major (Sewell, 1940), Lourinia armata minor (Sewell, 1940) and Lourinia armata sulamericana Jakobi, 1954), now considered direct child taxa, have been proposed to belong to this family in the past.…”

Mesophotic coral ecosystems (MCEs) are found on the insular and continental slopes of Caribbean islands and comprise mainly scleractinian corals, sponges and macroalgae. These species provide habitat for a highly diverse and specialized crustacean fauna. A new genus and species of the family Louriniidae is described from samples taken from an MCE in south-west Puerto Rico. The new taxa can be diagnosed by: body elongate, almost cylindrical and with inconspicuous podoplean boundary between prosome and urosome; double genital somite with a discontinuous chitinized cuticular ridge; telson short with rectangular anal operculum; furca short; rostrum sinusoidal, well defined at the base; antennules 7-segmented with aesthetasc on the fourth segment; antenna with a brush-like basal seta and an abexopodal seta, exopod 1-segmented with 2 setae; endopod with 7 elements (1 geniculate seta and 1 modified inner spine); maxilliped well developed, prehensile, composed of syncoxa, basis, one segmented endopod and one claw-like apical seta; leg 1 endopod 3-segmented, first segment with a modified inner seta; legs 2, 3 and 4 with 2-segmented endopod with inner seta on the first segment; leg 5 basendopod fused, well developed with 4 setae, exopod well developed, with 5 setae; leg 6 represented by a single seta; and genital slits wide apart. The new genus and species can be confidently assigned to the family Louriniidae on the basis of the following synapomorphies: rostrum well-developed with rounded tip; antennule of female 7-segmented; mandible palp reduced; maxillule endopod and exopod absent; maxillae endopodite 2 represented by 3 setae; leg 5 basoendopod of female confluent, intercoxal sclerite absent, exopod 1-segmented; eggs retained in a single ventral egg sac; telson shorter than last urosomite; and furca short and with 6 setae.

In this paper, two new species of Onychocamptus Daday, 1903 are described from Thailand: Onychocamptussatunensissp. n. and Onychocamptustratensissp. n. The following features mainly distinguish O.satunensissp. n. from known species: internal sausage-like and internal rounded structures on cephalothorax and one outer seta on the male P5 exopod that is as long as the supporting segment. In contrast, the cephalothorax of O.tratensissp. n. is smooth but has rounded integumental window-like structures, and the outer seta on the male P5 exopod is two times as long as the supporting segment. Onychocamptusanomalus shows the highest similarity with the two new species, but in contrast to both Thai species, it has only one seta on the exopod of the antenna. In addition, in the present study, two additional species, O.bengalensis and O.vitiospinulosa, are newly recorded in Thailand. Thus, the number of Onychocamptus species recorded in Thailand increases to five species. A key to all known species of this genus in the world is also proposed.

ABSTRACT. POPULATION STRUCTURE OF THE SEAWEED DWELLERHYALE MEDIA (DANA) (AMPII IPODA, GAMMARIDEA , HVALlDA E) FROM CAIOBÁ , MATlNIIOS, PARANÁ, BRAZIL.A study ofcolTelation between the tota l body length and the som ites length was c31Tied out in a population of l-fyale media (Dana, 1857), in order to know whi ch somite or group of som ites has the highest correlation index w ith the total body Iength. As the sum ofthe length ofthe first to fourth pereonites showed th e highest linear correlation index (Y=0.0764+0.2736X; r=0.9723), this meristic parameter was chosen to describe the population structure ofthe spec ies. The following aspects were treated: di stributi on of the body size classes in the various phytals, population compos itioll, seasonal Ouctuatioll of population density, relative freq uency of the ov igerous females and correlation between th e body length alld the number of eggs inside the marsupium 01' the ovigerous females. The amphipods were obtained from the seasona l collections of six phyta ls from a rocky seashore of Caiobá, Paraná State: Plerosiphonia pellnala (Roth) Falkenberg, Gymnogongrus griffithsiae (Turner) Martius, Pteroc/adia capillacea (G melin) Bornet & Thured, SargasslIIlI cymosum Garth, GelidiulJI sp and Uiva fasciata Delile; they did not occurred in Padilla gyll7llo;pora (Kútsing) Vickers and POIphyra alropurpurea (O liv i) De Toni. The ai r temperature osc illated from 16°C (winter and autumn) to 23°C (s ummer), the surtàce water temperature from 17°C (winter) to 25°C (summer) and the sllrlàce water salinity , Ii'om 29.3%. (autumn) to 32.8%. (winter). The density ofl-fyale media varied fro m 0.20 ind.g-I (in Uiva) to 26.37 ind.g-I (in Plerosiphonia) ofalga-substratum weigth, and th e population was distribllted mainly in branched a lgae. Tt was detennined three s ize classes in the population, within a range li'om 0.0 I to 2.99m111 of pereonits 1-4 length. Small amphipods prefer finely branched algae like Gyll1l1ogongrus and Pterosiphollia, whereas broad-thallii or less branched a lgae suc h as SargasslIm , Pleroc!adia, Gelidium and Uiva harbour proporcionally high number of large indi viduais. The life cycle of Hyale media takes place wholly in the phytals and the species reproduces cOlltinually ali year round: males, ovigerous females and juveniles are present every season. The highest female reproductive activity occurs in winter and the juveniles are more numerous in Sllmmer. The number of eggs inside the marsupiul11 and the pereonites 1-4 length has a linear correlation (Y=-9,9682+ 12,0729X; 1 = 0.8024).
