A New Species

A small number of treefrog species (Litoria) from Melanesia are unusual amongst Anura in having distinctive fleshy rostral spikes. Here, we first present an extended description for Litoria pronimia Menzies, a small species that is widespread along the southern edge of the Central Cordillera of New Guinea, and in which males have a long and erectile rostral spike. Second, we describe Litoria pinocchio sp. nov. a new, morphologically similar, yet geographically disjunct species from the Foja Mountains in northern Papua Province, Indonesia. The new species differs from Litoria pronimia in aspects of body shape, proportions and colouration. A review of variation in the size, structure and degree of sexual dimorphism of the rostral spike across different species of Litoria suggests varying function including mate selection and camouflage.

A New Species

An unusual new omaliine species, Anthobium alekseevisp. nov., is described and illustrated from Eocene Baltic amber, tentatively placed in the megadiverse genus Anthobium Leach, 1819. A new monotypic species-group is established. The new species can easily be distinguished from other species of the genus by the larger body, shape of the subrectangular pronotum, and the presence of a median carina on the prosternum and large, subtriangular tooth on the inner side of each mesotibia, likely exhibiting a peculiar sexual dimorphism in the male. Based on the study of the specimen with support of microtomographic images, a brief comparative analysis of a new species with described extant species of Anthobium is provided.

A New Species

Catinia aiso sp. n. was found in association with the mud shrimp, Axianassa australis Rodrigues & Shimizu, 1992 collected in the intertidal zone of Araçá Beach, state of São Paulo, Brazil (23°48’50’’S, 45°23’48’’W). The new species shares with Catinia plana Bocquet & Stock, 1957 the structure of the oral appendages, the setal formula of the swimming legs, the robust pedunculate sucker on the antenna, and the absence of the maxilliped in adult females. However, the two species can be separated by the rostrum shape, the presence or absence of an inner coxal seta on leg 4, and the structure of leg 5 in both sexes. Catinia aiso also differs from C. plana in the depressed ovoid body shape, the ornamentation of the maxilla in the female and in the modified claw of the maxilliped of the male. The sexual dimorphism expressed in the armature of the antennule and the endopodal segments of the swimming legs in C. plana, is absent in C. aiso. This is the first record of Catinia since the genus was established on the basis of material from the Baie de Morgat, France, in 1957.

A New Species

Extensive beds of sulphide-habitat-associated clams are present on the summit of Edison Seamount (1450 m depth) near Lihir Island, Papua New Guinea. These vesicomyids represent a new species. Imagery indicates that two major fields are several hundred metres in size. Four large grabs yielded over 270 live clams up to 23 cm in length plus many shells. The size structure of the populations suggests that settlement occurs in cohorts and that successful recruitment occurs mostly in areas with few adult clams. Dead juveniles were most abundant in the grabs with dense adults. Images from a towed camera sled included scales to allow density estimates that range up to 240 clams/m2 (in small patches) with sizes averaging around 16.5 cm in length. A biometric relationship for length to wet mass allows calculation of estimates of biomass represented by clams measured in photographs. The average biomass value in Lihir clam beds is 13.3 kg/m2, with maximum values over 29 kg/m2 (wet mass including shells). We compare these values with those of other studies that retrieved fewer specimens or imagery. We suggest that several overestimates populate the literature but that values around 30 kg/m2 rival the biomass of intertidal bivalve beds.

Synodontis acanthoperca, a new species of mochokid catfish, is described from rapids within the Ogôoué River system of Gabon. This relatively small species (<50 mm SL) is distinguished from all congeners by a distinctive pigmentation pattern that includes a pair of dark patches on the caudal fin and by the presence of hypertrophied opercular spines in sexually mature males.

A New Species

We describe a new species of bent-toed gecko in the genus Cyrtodactylus from hill forest in Southern Highlands Province, Papua New Guinea. Cyrtodactylus manos sp. nov. can be distinguished from all congeners in New Guinea by its small size in combination with aspects of colouration and body and tail scalation. The new species adds to the growing number of vertebrate species known only from karstic mountains along the southern edge of New Guinea’s Central Cordillera, suggesting that this region holds previously overlooked endemic karst-associated biota.
