A New Species

The biology of the moss and leaf litter inhabiting flea beetles is poorly understood. In this study, a new species of moss-eating flea beetles Cangshanaltica fuanensis sp. nov. is described; the morphology of adult and immature stages is examined and illustrated. Its life history and biology are studied. The remarkable and unique biological features are revealed: (1) females deposit one large egg at a time, egg length equals 0.4–0.5 times the female body length, these are unusual in Chrysomelidae; (2) females have only two ovarioles on each side of the ovary, which has not been reported in other Chrysomelidae species; (3) females lay and hide each egg under a spoon-shaped moss leaf; (4) cannibalism of a second instar larva on an egg was observed. Both adults and larvae feed on moss and are polyphagous; their feces mainly consist of un-digested moss fragments; high humidity is essential for the survival of eggs and larvae and expedites the hatching. In addition, a modified fan-driven Berlese funnel is designed for faster extraction of moss inhabiting flea beetles. This device could also be used for collecting other ground-dwelling arthropods. Its working diagram is illustrated and described.

AbstractThe adult, pupa, and final-instar larva of Trichothaumalea elakalensis sp.nov. (Diptera: Thaumaleidae) are described and illustrated. This is the first record of this genus from eastern North America and first description of the immature stages. In addition, reinterpretation of the homologies of the male terminalia and preliminary observations on the male reproductive system of Thaumaleidae are presented and the phylogenetic implications upon the monophyly of the Chironomoidea are discussed.

A new species of the genus Corythucha, C. bonaerensis n. sp., is described along with its egg and all immature stages. It was found in the province of Buenos Aires (Argentina) feeding on Quercus robur, its host plant. Comments on the life history of C. bonaerensis are provided together with photographs, and illustrations. The main differences with the other South American species, and other Corythucha species that feed on Quercus worldwide, are also discussed.

A New Species

During my recent studies on the lepidopterous miners in the needles of various conifers, I have found several undescribed species. One of them occurs near Ottawa, Ontario, and in Nova Scotia. It was also found in Quebec by Dr. J. M. McLeod and Mr. J. A. R. Ducharme, Forest Research Laboratory, Sillery, Quebec. I describe this species here, to enable those officers to report on the immature stages and life history in a companion paper that follows.

A new species of opilioacarid mite, Neocarus belizensis sp. nov., is described from mid-level elevations in Belize’s Maya Mountains. Laboratory observations confirmed that females nearly always deposit only one egg at a time, and that eggs are coated before deposition. Females guard both eggs and larvae. The larvae are non-feeding and molt quickly to protonymphs. Adults appear to facilitate feeding by protonymphs. Actual mating could not be observed, but pre-mating behavior is documented.

A New Species

Eucharissa (Hymenoptera: Eucharitidae) is an enigmatic genus within Chalcidoidea. Adults have at least 16 antennal segments, which is shared only by the closely related genus, Saccharissa, with some species of Eucharissa having as many as 22 antennal segments. At most, other Chalcidoidea have up to 14 segments. Phylogenetic analyses place Eucharissa within the poneromorph-ant attacking clade, but until now, the host and immature stages of this genus were unknown. Eucharissa insolitasp. nov. was discovered in two cocoons of Bothroponera granosa (Ponerinae) from South Africa; one a fully developed male and the other a second-instar larva. The larval exuviae present within the cocoons allowed for description of the life stages and comparison with other members of the poneromorph-attacking clade of Eucharitidae. Morphology of the pupa across Eucharitidae is reviewed, and synapomorphies of the immature stages are identified that support monophyly of the poneromorph-attacking clade within the tribe Eucharitini.

A New Species

Abstract Culex longitubus Somboon, Namgay & Harbach is described as a new species of the Mimeticus Subgroup of the subgenus Culex. The larva is most similar to the larva of Cx. tianpingensis Chen from China, but is distinguished by the length of the siphon and the anal papillae, the form of the comb scales and pecten spines, and the development of setae 7-P, 13-T, 1-X, and 4-X. The adults have wing markings and male genitalia similar to those of species of the Mimeticus Complex. Phylogenetic analysis of COI sequences revealed that the new species is closely related to Cx. murrelli Lien of the Mimulus Complex. The immature stages of the new species were found in stagnant pools and marshes at high altitudes in several districts of Bhutan.

Average Adult

Material collected in Loch Tannoch was allowed to macerate in a chemical nutrient. A rich crop of Euglena gracilis as well as other infusoria resulted. Eight months later, when the Euglena had encysted, many amoebae were found at the bottom of the receptacle. They constitute a new species, here named Amoeba hugonis. An average adult specimen, when extended, measures about 104x52·2µ. The nucleus consists of a central karyosome lying in the nuclear sap, separated from the cytoplasm by a wellmarked nuclear membrane. Between the latter and the karyosome is situated an achromatic ‘collar’ with chromatin particles embedded in it. Fission is described, but a study of mitosis has been deferred. The life-history of this small amoeba is very similar to that of the large A. proteus, &c. The cycle occupies two months. Chromidia begin to appear in the cytoplasm of the early adult. They give rise to spores, out of which amoebulae hatch.

Anopheles (Nyssorhynchus) deaneorum sp. n. is described from specimens collected in Guajará-Mirim, Rondônia state and Rio Branco, Acre state, Brazil, on human and animal baits, inside dwellings and from the progenies of engorged females. A detailed description of the shape of egg, external appearance of adult female and male, genitalias, female cibarial armature and complete chaetotaxy of pupa and larva show that it can be distinguished from Anopheles albitarsis from the type-locality and other areas by the paler general external appearance of the adult, the posterolateral tufts of scales, on the female abdominal terga and the branching of the outer anterior clypeal seta (3-C) of the fourth instar larva (as shown in illustrations). If species can also be distinguished from An. albitarsis from the type locality by the allele frequencies at 11 enzymic loci as represented by Nei's Genetic Distance.
