Oil Characteristics

Over 400 specimens from 26 locations, mainly in the Lesser Sunda Islands and some from New Guinea and northern Cape York, were examined. These were representative of an array of forms ordinarily assigned to Eucalyptus urophylla, E. pellita and an undescribed species as well as those considered by some to be hybrid between E. alba and E. urophylla. The latter has long been considered to show considerable polymorphism. Re-examination of the available material and records suggest that interspecific hybridisation is not significantly involved in this variability. Although this examination pointed to the existence of some differentiation at the level of species in this array, there was still a core of material which could not be separated readily into subgroups. Measurements were taken of selected floral and foliar morphological features which were then subject to statistical analysis to ascertain if subgroups were discernible on this basis. As a result, the separation of two species, Eucalyptus orophila sp. nov. and Eucalyptus wetarensis sp. nov. from Eucalyptus urophylla sensu lato in the Lesser Sunda Islands, is supported. The related populations called species A by Pinyopusarerk et al. (1993), from New Guinea and northern Cape York, were to a somewhat lesser extent separated on these criteria. These results were paralleled by evidence from seedling morphology and oil characteristics. Isozyme analysis gave a similar grouping for the material from Wetar, but did not indicate other separations from the core E. urophylla.

Length Width

Twenty two populations of Eucalyptus urophylla, 13 of E. pellita and two of E. scias were selected throughout the species' natural distributions in Indonesia, Papua New Guinea and Australia, and the morphology of seedlings compared under greenhouse conditions. Leaf length, width, length/width ratio, base angle, stem shape and, to a lesser extent, intranode length provided good discrimination between species and provenances. Canonical variate analysis revealed four groups, two of which contain E. urophylla, one E. pellita and one E. scias. Wetar Island provenances formed one of the two E. urophylla groups, distinguished from the other group consisting of Alor, Adonara, Flores, Pantar and Timor provenances on the basis of narrower leaves, greater length/width ratios, more acute leaf base angles and square stems. Seedling leaves of E. pellita were generally longer and broader than the other species, with a tendency for a separation between the northern occurrences (New Guinea and northern Cape York Peninsula, Queensland) and southern occurrences (Helenvale to Rockhampton, Queensland); those from the north had smaller leaves and more distinctly square stems. E. scias is clearly distinguished by its narrower leaves and longer intranode length.

The Australian Tortricini, Schoenotenini, and Chlidanotini together include 40 species in 17 genera. The Tortricini which are represented by 16 species in six genera, fall into two groups, the Phricanthes group with two genera and the Eboda group with four genera. Phricanthes Meyr. contains four Australian species, P. peistica and P. diaphorus being described as new. The other two species have a wide distribution abroad. The larvae attack plants in the family Dilleniaceae. The endemic genus Scolioplecta Meyr. includes seven widely scattered species, of which S. exochus and S. allocotus are described as new. A new species, A. diapella, from the Cape York Peninsula is referred to Amboyna Razowski, based on an Indonesian species. Anameristes, gen. nov. is a monotypic genus from north Queensland rain forest, established for Eboda cyclopleura Turn. Eboda Walk, contains one Australian species, and a series of others in the Indo- Malayan and Papuan areas. Asterolepis Razowski includes three species from Australia and New Guinea, with A. earina from Cape York and A. brandti from Papua described as new. The Schoenotenini are represented by 19 Australian species in seven genera. Two elements are distinguished. The Proselena group ranges from India to the New Hebrides and Rapa, including eastern Australia and New Zealand, while the Schoenotenes group has reached its greatest diversity in New Guinea. Proselena Meyr, has two species; Syncratus, gen. nov. has two new species, S. scepanus and S. paroecus; Tracholena, gen, nov., with type species Cnephasia sulfurosa Meyr., has three species; and Palaeotoma Meyr. is monotypic. The larvae of Proselena are leaf miners in Bursaria, those of T. sulfurosa tunnel in the bark of exotic Cupressus, while Palaeotoma has larvae boring in insect galls on Eucalyptus. Larval characters of these are discussed and compared with those of the New Zealand Prothelymna and Dipterina. The wide-ranging Diactenis Meyr., with a single new Australian species D. tryphera, may also belong to this group. Two genera of the Schoenotenes group are known from Australia. Cornuticlava Diak. includes three rain forest species in northern Queensland, including C. aritrana and C. phanera described as new. Epitrichosma Low. contains seven Australian species, one of which comes from the Darwin area, another E. hesperia, sp. nov. from south-western Australia, one from rain forest in southern Queensland and eastern New South Wales, and four including two new species E. ceramina and E. metreta from north-eastern Queensland. The last also occurs in New Guinea. The Chlidanotini contain five Australian species in four genera. Trymalitis Meyr. and Caenognosis Wals. are small but widely distributed Old World genera. The two new monotypic endemic genera Daulocnema, based on D. epicharis, sp. nov., and Leurogyia, based on L. peristictum, sp. nov., are described. The venation, genitalia, mouth-parts, and other adult structures, used to distinguish the genera, together with the larval characters of a few species, are discussed and figured. The genitalia of both sexes and the wings of the Australian species are figured and keys to the genera and species are given.

Two New Species

Additional work on the islands of Vanuatu has improved our understanding of the actual diversity of South Pacific coastal fireflies. Prior to recent fieldwork in Vanuatu, the only known lampyrid from Vanuatu was Atyphella aphrogeneia (Ballantyne), a coastal species also found in Papua New Guinea. After further examination, we determined that specimens from Vanuatu formerly classified as Atyphella aphrogeneia actually belong to an undescribed species. New species, Atyphella maritimus Saxton and Powell and Atyphella marigenous Saxton and Bybee, are described from specimens collected in Vanuatu. An updated key for coastal Atyphella in the South Pacific is provided.

The green-eyed treefrogs (Litoria eucnemis species-group) are found throughout New Guinea and some of its offshore islands, and in two geographically separated regions in north-eastern Queensland, Australia. We examine the genetic relationships among populations of the complex from across its range and find that populations fall into two major lineages: 1) specimens referable to L. genimaculata from New Guinea and its offshore islands, and L. exophthalmia, and 2) samples referable to L. eucnemis from New Guinea and northern Cape York, Australia, and two lineages from the Wet Tropics of north-eastern Australia that are currently assigned to L. genimaculata. Based on our molecular genetic analyses, morphological assessment of new collections and re-examination of type material, we retain L. eucnemis as currently recognised for northern Cape York populations but resurrect the name L. serrata for the Wet Tropics populations. The degree of reproductive isolation between the two Wet Tropics lineages is being studied currently and so at this point we refer both to L. serrata. The degree of genetic variation observed in L. genimaculata across New Guinea locations and possible paraphyly with L. exophthalmia suggest the presence of additional undescribed species. Reexamination of type material and collection of new specimens, allow us to reassess the status of several other names currently synonymised with L. eucnemis and L. genimaculata. Our observations support the present synonymy of Hyla rhacophorus with L. eucnemis and we remove Nyctimystes loveridgei from the synonymy of L. genimaculata and place it in the synonymy of L. eucnemis.

Land Planarian

The Brazilian land planarians Cratera crioula, C. joia, Geoplana hina, and G. taxiarcha (Platyhelminthes, Tricladida, Geoplanidae) are revised taxonomically from type material and additional specimens. Geoplana hina sensu Carbayo et al. (2013) was found to be an undescribed species and therefore is described and named as Cratera picuia sp. n. A new species of the genus is also described and named as Cratera arucuia sp. n. G. hina and G. taxiarcha are transferred to Cratera. The most remarkable morphological feature of Cratera—a dilated terminal portion of the ejaculatory duct—is either absent, inconspicuous, or variable in C. hina, C. joia, C. picuia sp. n., and C. arucuia sp. n. Based on the monophyletic status of Cratera inferred elsewhere, an emendation of the genus is here proposed to encompass the morphological variation observed in the genus.
