The genus Elsiella Froeschner, 1981 is validated based on the analysis of a recently found male specimen of E. plana(Walker, 1867). A cladistic analysis comprising a data set of 40 morphological characters and 22 taxa, including the generaElsiella, Serdia Stål, Similliserdia Fortes & Grazia, Neotibilis Grazia & Barcellos, and Tibilis Stål, was performed. Elsiellaplana is redescribed and illustrated. Maps are provided for Elsiella and Serdia with biogeographical considerations for Serdia.

Three New Species

The present work brings together the dispersed information on the Neotropical genus Chloropepla. It was established in 1867 by Stål and reviewed in 1968 by Grazia; since the revision, ten new species have been added. In this work a cladistic analysis of the species of Chloropepla is presented. The monophyly of the genus was confirmed. Three monophyletic groups of species were identified: clade A (C. rideri sp.n., C. paveli, C. vigens, C. luteipennis), clade B (C. costaricensis sp.n., C. aurea and C. pirani) and clade C (C. dollingi, C. tucuriuensis, C. stysi, C. caxiuanensis sp.n. and C. rolstoni). An extended description of the genus and diagnoses for the species are provided. Three new species from Costa Rica, Venezuela and Brazil are described extending the northern distribution of the genus into Central America. A key to the species is also provided.

Biogeographical Analysis

In this paper, Brachystethus Laporte, 1832 is analyzed cladistically, using 21 characters and 15 taxa, including as outgroups, in a first analysis, the genera Neotibilis Grazia & Barcellos, 1994, Edessa Fabricius, 1803, Olbia Stål, 1862, Peromatus Amyot & Serville, 1843, and Pantochlora Stål, 1870. Further, these edessine genera were included in the ingroup, without any changes in the only resulting cladogram. The monophyly of Brachystethus is supported by four synapomorphies: metasternal carina partially bifurcated, pygophore with blade-like processes, anterior margin of gonocoxites 9 deeply concave medially, and a mesial thickening on gonapophyses 9. Brachystethus shares with Edessa, Olbia, Pantochlora, and Peromatus four synapomorphies: loss of subcallous margin on pronotum, mesosternal carina lower than metasternal carina, phallus with a short vesica, and presence of a beak-like projection on the thickening of vaginal intima. Based on the cladogram, the transferal of Brachystethus to Edessinae is here proposed. Biogeographical analysis has shown congruence between the distributional pattern of the clade formed by B. rubromaculatus Dallas, 1851, B. signoreti Stål, 1872, B. cribrus (Fabricius, 1781), and Brachystethus sp. nov. A, and vicariant events on Neotropical region, in the late Cretaceous.

A New Species

Odontopleura (Odontopleura) arctica, a new species of odontopleurine trilobite, is described from the Canadian Arctic. A method of cladistic analysis is detailed. Parsimony analysis should be performed treating all characters as unordered. The universe of directed trees implied by the resulting rootless network(s) can then be examined and a preferred tree selected by a criterion of congruency. Namely, the most parsimonious directed tree that accommodates the most congruent arrangement of character-states should be taken as the preferred cladogram. Since this is essentially a general congruency method operating within the constraints of parsimony, it is termed “constrained congruency.” The method is applied to the genus Odontopleura, resulting in the recognition of two major species groups, the nominate subgenus and Sinespinaspis n. subgen. Odontopleura (Ivanopleura) dufrenoyi Barrande is tentatively included in the genus, but considered too poorly known for cladistic analysis. Species assigned to Odontopleura (Odontopleura) include Odontopleura ovata Emmrich, Odontopleura brevigena Chatterton and Perry, Odontopleura (Odontopleura) arctica n. sp., and Diacanthaspis serotina Apollonov. Species assigned to Sinespinaspis n. subgen. include Taemasaspis llandoveryana Šnajdr, Odontopleura greenwoodi Chatterton and Perry, Odontopleura maccallai Chatterton and Perry, and Odontopleura nehedensis Chatterton and Perry. Odontopleura bombini Chatterton and Perry is tentatively placed in synonymy with Odontopleura nehedensis. The genus had a wide distribution throughout the Early and Middle Silurian, due to preferences for deep-water, distal shelf or shelf-slope transition zone habitats.

Biological control has been reducing the use of chemical products against insect pests, specially predatory Pentatomidae. Species of this group can present high variations in their life cycle as a result of their diet. Thus, the objective of this research was to study nymph development and reproduction of Podisus distinctus (Stäl, 1860) (Heteroptera: Pentatomidae) fed on Bombyx mori L., 1758 (Lepidoptera: Bombycidae) larvae (T1), compared to those fed on Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae) (T2) and Musca domestica L., 1758 (Diptera: Muscidae) larvae (T3) at a temperature of 25 ± 0.5ºC, relative humidity of 70 ± 2%, and photophase of 12 h. Predators fed on B. mori showed duration of the nymph phase (18.68 ± 1.02) similar to those fed on T. molitor (18.32 ± 1.49). Pre-oviposition and oviposition periods and number of egg masses, besides eggs and nymphs per female, were higher with B. mori (5.83 ± 2.02; 15.00 ± 7.40; 8.42 ± 1.84; 296.69 ± 154.75; and 228.55 ± 141.04, respectively) while longevity of males and females of P. distinctus was 25.76 ± 16.15 and 35.00 ± 16.15 days with T. molitor, and 20.57 ± 13.60 and 23.46 ± 12.35 days with B. mori, respectively.
