Additional Collection

Elaeagia Wedd., a genus of some 16 species belonging to the tribe Rondeletieae, is centered in South America with a single species known from Cuba. Two additional species occur in Central America, one of which, E. nitidifolia Dwyer, is known only from Panama. The other, E. auriculata Hemsl., extends as far north as Guatemala (Standley & Williams , 1975; Dwyer, 1980). Most members are large trees, some attaining 35 meters, although the Cuban species is said to be shrubby (Standley, 1921). All known species occur in montane forest at altitudes of 800 to 2 800 meters. Consequently, it was surprising to see material, apparently representing an undescribed species, from lowland tropical rain forest in SE Oaxaca and adjacent Veracruz in Mexico. However, Dr. Tom Wendt's collecting efforts towards a woody flora of the Uxpanapa Zone have yielded a number of range extensions for taxa previously known only from Central America or Chiapas. Significantly, this region lies at the northern limits of the area to be included in Flora Mesoamericana. An additional collection is known from montane forest at 1 100 m in northern Chiapas, a habitat more typical for the genus .

Endemic Genera

The endemic Hawaiian sap beetles were originally placed in 13 genera in 1908; Apetasimus, Apetinus, Cillaeopeplus, Cyrtostolus, Eunitidula, Eupetinus, Gonioryctus, Goniothorax, Nesapterus, Nesopeplus, Nesopetinus, Notopeplus, and Orthostolus. Apetasimus, Cyrtostolus, Eunitidula, and Notopeplus were described for single species, with additional species later described for Apetasimus and three undescribed species known for Eunitidula from Oahu, Molokai, and West Maui. Nesopeplus and Nesopetinus have been previously shown to be junior synonyms of Prosopeus. The monophyly of the genera is tested using morphological characters, primarily of the male copulatory sac, in a parsimony framework. The results provide the rationale for reducing the number of endemic genera to six; Apetasimus (= Cyrtostolus + Orthostolus in part), Cillaeopeplus (= Notopeplus), Eupetinus (= Apetinus), Gonioryctus (= Eunitidula + Goniothorax + Nesapterus), Orthostolus s.s., and Prosopeus. Brachypeplus (= Cillaeopeplus) gracilis, a species endemic to Guam, was placed in the formerly Hawaiian endemic Cillaeopeplus in 1962. Examination of the types of all species of Cillaeopeplus shows no direct connection between B. gracilis and the Hawaiian taxa comprising the remainder of Cillaeopeplus. Brachypeplus gracilis is placed incertae sedis in Brachypeplus herein. The position of the endemic Hawaiian sap beetles within the nit idulid subfamily Cillaeinae is surveyed using exemplar species from 22 of 27 genera placed in Cillaeinae. Undescribed species from eastern Polynesia allied with Brachypeplus subgenus Selis are proposed as the closest relatives of the Hawaiian endemic sap beetles based on internal and external morphology.

AbstractExtensive collections of synanthropic fly parasitoids in animal excrement accumulations in the United States, Mexico, Costa Rica, Puerto Rico, Uruguay, Chile, Denmark, Israel, and South Africa yielded seven forms of a Muscidifurax complex which were totally or partially reproductively isolated. Morphological studies of female and male parasitoids coupled with biological and zoogeographical information permitted the identification of five sibling species. Muscidifurax raptor Girault and Sanders 1910 is redescribed and four additional species are described as new: M. zaraptor, from the southwestern United States; M. raptoroides from Central America and Mexico; M. uniraptor from Puerto Rico, and M. raptorellus from Uruguay and Chile. Biological notes are added to the descriptions, and it was postulated that the genus is undergoing a process of speciation with local populations slowly becoming reproductively isolated and eventually giving rise to morphologically distinguishable entities. Most evidence suggests the establishment of Muscidifurax in the New World, concomitant with or shortly following the establishment of muscoid flies in accumulated excrement. Scanning electronmicroscopy was used in the analysis of some morphological structures.

Primary Habitat

Habitat utilisation and foraging behaviour by the common striped possum (Dactylopsila trivirgata) was investigated by means of spotlighting and radio-tracking at Shiptons Flat, far north Queensland. Vine forest was the primary habitat of D. trivirgata; however, animals were also observed in open eucalypt (Eucalyptus tereticornis) woodland. Information collected on foraging behaviour suggests that D. trivirgata are generalist insectivores consuming some fruit and other foodstuffs, such as honey. Radio-tracking data were used to calculate the home-range areas of two subadult males. The home range of the smaller male (body weight 290 g) was 5.2 ha (by the 95% harmonic mean (HM) method) or 6.5 ha (by the minimum convex polygon (MCP) method), and that of the larger male (body weight 415 g) was 21.2 ha (95% HM) or 21.3 ha (MCP). Large trees with hollows, which are utilized for denning, appear to be an important feature of the habitat for this species. D. trivirgata exhibits a pronounced degree of sociality and may breed seasonally. Observations suggest that amethystine pythons (Morelia amethistina) may be major predators of D. trivirgata at Shiptons Flat.

We measured carbon stocks at two forest reserves in the cloud forest region of Monteverde, comparing cleared land, experimental secondary forest plots, and mature forest at each location to assess the effectiveness of reforestation in sequestering biomass and soil carbon. The biomass carbon stock measured in the mature forest at the Monteverde Institute is similar to other measurements of mature tropical montane forest biomass carbon in Costa Rica. Local historical records and the distribution of large trees suggest a mature forest age of greater than 80 years. The forest at La Calandria lacks historical documentation, and dendrochronological dating is not applicable. However, based on the differences in tree size, above-ground biomass carbon, and soil carbon between the Monteverde Institute and La Calandria sites, we estimate an age difference of at least 30 years of the mature forests. Experimental secondary forest plots at both sites have accumulated biomass at lower than expected rates, suggesting local limiting factors, such as nutrient limitation. We find that soil carbon content is primarily a function of time and that altitudinal differences between the study sites do not play a role.

The morphology of the genus Scapheremaeus Berlese, 1910 is reviewed and characters of taxonomic utility delineated. Based on the morphological review, some 13 species-groups are outlined based on major morphotypes. There are two main categories: i) species that have a complete circumdorsal scissure with plicate microsculpture on the circumnotogastral plate and strongly contrasting microsculpture (foveolae, ridges or tubercles) on the centrodorsal plate (plicate species-groups), and ii) species with the circumdorsal scissure complete, incomplete or absent but with little or no contrast in microsculpture between the central and lateral regions: typically both regions foveolate or reticulate (non- plicate species-groups). A catalogue of world species of Scapheremaeus is provided. Scapheremaeus petrophagus (Banks, 1906) is not a Scapheremaeus but belongs to an undetermined genus in the Ameronothroidea. Cymbaeremaeus cyclops Oudemans, 1915 is recombined to Scapheremaeus. Five new species are described (S. angusi sp. nov., S. cheloniella sp. nov., S. ewani sp. nov., S. lambieae sp. nov., and S. pulleni sp. nov.) from soil and litter habitats in semi-arid Mallee eucalypt vegetation at Bookmark Biosphere Reserve, South Australia. These are the first members of the genus Scapheremaeus to be described from Australia, though undescribed species have been recorded previously. All the new species are morphologically closely-related and belong to a single species-group: Carinatus.

Three New Species

Of the 92 Codonoboea species that occur in Peninsular Malaysia, 20 are recorded from the state of Terengganu, of which 9 are endemic to Terengganu including three new species, C. norakhirrudiniana Kiew, C. rheophytica Kiew and C. sallehuddiniana C.L.Lim, that are here described and illustrated. A key and checklist to all the Terengganu species are provided. The majority of species grow in lowland rain forest, amongst which C. densifolia and C. rheophytica are rheophytic. Only four grow in montane forest. The flora of Terengganu is still incompletely known, especially in the northern part of the state and in mountainous areas and so, with botanical exploration, more new species can be expected in this speciose genus.

Recent Attention

Recent attention to members of the sepiolid squid genusEuprymnaand symbiotic associations with luminescent bacteria (Vibrio fischeristrains) has prompted a review of this poorly-resolved group of squids. Twelve nominal species have been placed in this genus of which the majority are ill-defined, known only from their original descriptions and separated on the basis of inadequate characters. As a first step in resolving this group, a temperate Australian species, the Southern dumpling squid,Euprymna tasmanica, is here redescribed in detail. As the genusEuprymnacurrently stands, most members are only distinguished on the number and position of enlarged suckers in mature males. No diagnostic characters are available to identify females. All nominal species placed in this genus are reviewed and a key to proposed valid species is presented. Six species are considered here to be valid:Euprymna berryi, E. hoylei, E. morsei, E. scolopes, E. tasmanicaand an undescribed species treated here asEuprymnasp. 1.Euprymna similisis a synonym ofE. morseiof Japan. Due to inadequate original descriptions, and lost or poor type material, two species are considered here to benomen dubia(E. schneehageniandE. pusilla), while the taxonomic status of four additional species remain unresolved (E. albatrossae, E. bursa, E. phenaxandE. stenodactyla).

Abstract:The upper canopy of some rain forests in New Caledonia is dominated by single species. These monodominants are commonly secondary species, their dominance not persisting without disturbance. We tested whether dominance is associated with efficient uptake and use of nutrients (N, P and K), comparing between seedlings of monodominants (Nothofagus spp., Arillastrum gummiferum and Cerberiopsis candelabra) and 14 subordinates, grown in a nursery house. We also tested whether this trend applies more broadly to shade-intolerant trees that regenerate episodically (ER species) versus shade-tolerant trees that regenerate continuously (CR species). In the sun treatment, monodominants had higher photosynthetic nutrient-use efficiency and productivity for N and K, and uptake efficiency for N, P and K, than subordinates; ER species had higher photosynthetic nutrient-use efficiency for N, P and K, and uptake efficiency for N and P, than CR species. Uptake efficiency and productivity per nutrient mass were uncorrelated across species, yet Nothofagus spp., A. gummiferum and C. candelabra combined high levels of both traits for N, and Nothofagus spp. and A. gummiferum combined moderate to high levels for P, in sun-grown seedlings. This trait combination may contribute substantially to competitiveness and post-disturbance dominance on these nutrient-poor soils.
