The population ecology of Amorbus Dallas (Hemiptera: Coreidae) species in Australia

Species of Amorbus Dallas (Hemiptera: Coreidae) appear to exhibit a tight link between oviposition preference and nymphal performance: females apparently select vigorous plant modules to facilitate the development of their offspring. Such behaviour suggests that these insects should exhibit population dynamics consistent with the latent classification proposed by Price et al. (1990). While this empirical hypothesis is intuitively appealing it does not appear to incorporate current population dynamics theory. Berryman's ecodynamics (1992) offers the potential to describe a species' population dynamics which is grounded in a quantitative theoretical framework. The population ecology of Amorbus species from Australia is considered in relation to these hypotheses.

Appendage Homologies and the First Record of Eyes in Platycopid Ostracods, with the Description of a New Species of Keijcyoidea (Crustacea: Ostracoda) from Japan

A median nauplius eye is reported for the first time in a platycopid ostracod, a group hitherto considered to be blind. A new species of the platycopid ostracod genus Keijcyoidea is described from coastal rocky marine habitats on the Pacific coast of Japan. Observations of living specimens in the laboratory show that it is capable of burrowing to a depth of several millimeters in sandy sediment, using the first two head appendages (antennulae and antennae) and the furca. Females brooded a maximum of five eggs in the posterior brood space of the carapace. The homologies and phylogenetic implications of the trunk segmentation and limbs are discussed, paying particular attention to the sexually dimorphic fifth and sixth limbs; the copulatory appendages of both sexes are interpreted as being attached to trunk segments T6–T7 (counting from the posterior; T1 = posteriormost segment).     

Revision of the Neotropical genus Nyttum (Hemiptera: Coreidae)

Abstract The Neotropical genus Nyttum, belonging to the wholly New World tribe Acanthocephalini of the plant-feeding heteropterous family Coreidae, is redescribed. Its distribution is shown to extend from Mexico to Uruguay. Nyttum limbatum Spinola, from Brazil, and N.punctatum (Dallas), widespread in South and Central America, are redescribed; Anasa perfusa Distant is synonymized with N.punctatum. Seven new species are described: Nyttum amaralae, from Uruguay; N.beckeri, from Brazil and 'West Indies' N.nigrum, from Venezuela; N.pallens, from Mexico; N.pulchrum, from Peru; N.rubrum, from Brazil; and N.spinolai from Brazil and Guyana. A key to the species is included. Placoscelis is regarded as the genus most closely related to Nyttum and it is shown that the same two types of paramere and the same two types of aedaegus occur in both genera.  

Resumen

. Se redescribe el género neotropical Nyttum, perteneciente a la tribu Acanthocephalini que se encuentra exclusivamente en el Nuevo Mundo, dentro de la familia Coreidae (Hemiptera-Heteroptera) que se alimenta exclusivamente de vegetales. Se indica que la distribución de este género se extiende desde Mexico al Uruguay. Se redescriben Nyttum limbatum Spinola del Brasil y N.punctatum (Dallas), de amplia distribución en América del Sur y Central. Anasa perfusa Distant es sinonimizada con N.punctatum. Se describen siete neuvas especies: Nyttum amaralae, del Uruguay; N.beckeri, del Brasil e 'Indias Occindentales' N.nigrum, de Venezuela; N.pallens, de Mexico; N.pulchrum, de Perú; N.rubrum, de Brasil; y N.spinolai, de Brasil y Guyana. Se incluye una clava para la separation de las especies. Se considera que Placoscelis es el género mas cercano a Nyttum, y se indica que los mismos dos tipos de parameros y los mismos dos tipos de aedeagus se encuentran en ambos.     

Morphology of Immatures of Caonabo pseudoscylax (Bergroth) (Hemiptera: Pentatomidae)

Characters of immatures are potentially useful in identifying taxa, but few immatures of Pentatomidae were described. The objectives here are to describe the egg and five nymphal instars of Caonabo pseudoscylax (Bergroth) under light and scanning electron microscopy. Adults, eggs, and nymphs were collected on Homolepsis glutinosa during 2008, in Criciúma (Santa Catarina, Brazil). The egg of C. pseudoscylax is subcylindrical, chorion reddish brown, slightly translucent, and with granulate surface. Aero-micropylar processes translucent, spongy, and strongly clavate. Nymphs without punctures, spiracles placed near the lateral abdominal margin. The dorsal abdominal gland has rounded ostioles bearing cuticular valve; spout peritreme smooth, directed anteriorly; evaporatorium network-shaped; and microsculpture poorly ornamented. Humeral angles of the pronotum were produced from fourth instar. The almost marginal placement of abdominal spiracles may diagnose the nymphs of C. pseudoscylax from first instar to adulthood.
