The genus Penares Gray 1867 (Tetractinellida Marshall; Astrophorina Sollas; Geodiidae Gray) is reviewed from new and existing New Zealand collections, with 75 specimens examined and registered. The only species known from New Zealand prior to this study, P. tylotaster Dendy 1924, is re-examined and re-described from the holotype, using new scanning electron microscope images. Nine new species are described from New Zealand’s Exclusive Economic Zone: P. mollis sp. nov., P. aureus sp. nov., P. vermiculatus sp. nov., P. kermadecensis sp. nov., P. turmericolor, sp. nov., P. deformis sp. nov., P. okokewae sp. nov., P. orbis sp. nov., and P. astronavis sp. nov. A specimen of P. schulzei (Dendy 1905), first described from Sri Lanka and subsequently recorded from New Caledonia, was also found in New Zealand, extending the range of this species. This study brings the total New Zealand Penares fauna to 11 species, making a significant contribution to the now, global total of 39 species. All previously described Penares species are reviewed based on their published descriptions, and species names have been corrected to their masculine form. Based on the published description of P. obtusus Lendenfeld 1907, it is recommended that this species be reassigned to the genus Stelletta Schmidt 1862.

The nematode genus Bulbocephalus Rasheed, 1966 (Nematoda, Physalopteridae) was found to be a homonym of Bulbocephalus Watson, 1916 (Apicomplexa) and, therefore, a new name, Rasheedia n. nom., is proposed to substitute it. Based on light and scanning electron microscope studies of specimens collected from the digestive tract of perciform fishes off New Caledonia, two new species of Rasheedia are described: R. heptacanthi n. sp. from the Cinnabar goatfish Parupeneus heptacanthus (Mullidae) (type host) and Dentex fourmanoiri (Sparidae), and R. novaecaledoniensis n. sp. from the Indian goatfish Parupeneus indicus (Mullidae). These new species are mainly characterized by the number of anterior protrusible oesophageal lobes (two in R. heptacanthi and four in R. novaecaledoniensis), structure of the oesophagus and the lengths of spicules. An amended diagnosis of Rasheedia and a key to species of this genus are provided. Three previously described congeneric species are transferred to Rasheedia as R. deblocki (Le-Van-Hoa, Pham-Ngoc-Khue & Nguyen-Thi-Lien, 1972) n. comb., R. inglisi (Rasheed, 1966) n. comb. and R. pseudupenei (Vassiliadès & Diaw, 1978) n. comb. Cestocephalus Rasheed, 1966 [genus inquirendum], including C. serratus Rasheed, 1966 and C. petterae (Le-Van-Hoa, Pham-Ngoc-Khue & Nguyen-Thi-Lien, 1972) n. comb., should be considered to be separate from Rasheedia. The names Pseudomazzia Bilqees, Ghazi & Haseeb, 2005 and P. macrolabiata Bilqees, Ghazi & Haseeb, 2005, established for a nematode somewhat resembling Rasheedia spp., should be considered nomina dubia. Rasheedia heptacanthi n. sp. and R. novaecaledoniensis n. sp. are the first representatives of the Physalopteridae recorded from fishes in New Caledonian waters.

The species ofMeranoplusSmith, 1853 of the Arabian Peninsula are reviewed based on the worker caste. Two species are recognized, keyed, and illustrated by Scanning Electron Microscope images (SEM),Meranoplus mosalahiandM. pulcher, Sharaf, 2014.Meranoplus mosalahisp. n.is described from the Dhofar Governorate, Oman based on the worker caste. The new species belongs to theM. magrettii-group and closely resemblesM. pulcherSharaf, 2014 from the Kingdom of Saudi Arabia (KSA), from which it can be distinguished by the bicolored body, the shallowly concave anterior clypeal margin, the absence of well-developed anterior clypeal teeth, the fewer irregular longitudinal cephalic rugae, and the feeble longitudinal rugae on posterior face of petiolar node.

The first pararchaeid species to be recorded from outside Australia or New Zealand, Flavarchaea humboldti n. sp., is described from female specimens collected near the summit of Mont Humboldt, New Caledonia. Morphological and behavioural data are further described for Western Australian species of Ozarchaea Rix, with the spinneret spigot morphology of O. harveyi Rix imaged under a scanning electron microscope, and the egg sac of O. westraliensis Rix described for the first time. Pararchaeid spinnerets possess two major ampullate gland spigots on the anterior lateral spinnerets and no triad on the posterior lateral spinnerets; such a spinneret spigot arrangement does not support the placement of the Pararchaeidae in the superfamily Araneoidea, and further research is needed to test the phylogenetic position of this enigmatic family.

The genus chiton Loricella is revised. It comprises nine species. Two of these species, L. neoguinensis n. sp. and L. solomonensis n. sp., are described as new. Based on the analysis of morphological features studied using a scanning electron microscope, a revised diagnosis of the genus is provided. The characters diagnostic for this that distinguish it from the related genus Squamophora are as follows: a tubular hollow inside the dorsal scales, bristles on the dorsal side of the girdle, a wide ventral mouth region, a narrow mantle fold covered with simple longitudinally ribbed scales, smooth ventral scales, pits arranged in longitudinal rows in the central area of the tegmentum, and a bicuspid head of the major lateral teeth of the radula.

Introduction: The knowledge of polychaetes in the subtropical region of Africa benefited from the activity of J. Day. However, 50 years after the publication of his Monograph of the Polychaeta of southern Africa, it is necessary to reconsider the identity of the Cirratulidae due to changes in the diagnostic characters and new approaches to the taxonomy of the group to corroborate the status of cosmopolitan species in this region. Objective: We hypothesize that biodiversity of multitentacular Cirratulidae polychaetes has been significantly underestimated in southern Africa. Methods: The present work analyzes material deposited in the Iziko museum, as well as recently collected specimens, using scanning electron microscope to identify them. Results: The material corresponds to two new species belonging to the genus Protocirrineris. Protocirrineris strandloperarum sp. nov. is characterized by having the tentacular filaments between the chaetigers 5 to 10-12 and the first pair of branchiae from chaetiger 7, and P. magalhaesi sp. nov. is characterized by having tentacular filaments between chaetigers 4-8 and the first pair of branchiae from chaetigers 2 or 3. Descriptions of these species, with light and scanning electron microscope images, are given. Schematic drawings of the two new species are shown comparatively with diagnostic characters. Conclusions: The use of new techniques enables discovery of new taxonomic characters and two new species of the genus. The diversity of Cirratulidae polychaetes is underestimated also in the subtropical and tropical regions of Africa.
