Sexual selection, male morphology, and the efficacy of courtship signalling in two wolf spiders (Araneae: Lycosidae)
It is hypothesized that the tufts of the brush-legged wolf spider serve to increase the efficacy of visual displays of S. ocreata, as vibratory communication is constrained by the complex leaf litter habitat of some populations, which may make visual signalling over distance a critical factor for effective courtship communication.
Molecular Evidence of Cryptic Species within the Liriomyza huidobrensis (Diptera: Agromyzidae)

Maximum parsimony analysis of mitochondrial cytochrome oxidase I and II genes showed that L. huidobrensis contains two well-defined monophyletic groups, one composed of specimens from California and Hawaii and one composed from South and Central America together with populations that have been recently introduced into other parts of the world.
DNA Barcoding Applied to Invasive Leafminers (Diptera: Agromyzidae) in the Philippines
It is concluded that although a DNA barcoding approach can provide rapid species identifications, in certain instances it is likely to either overestimate or underestimate the number of species present.
Molecular phylogenetics and the evolution of host plant associations in the nematode genus Fergusobia (Tylenchida: Fergusobiinae).

- 1 October 2007
Phylogenetic analysis of sequences from D2/D3 and mtCOI, separately and combined, revealed many monophyletic clades within Fergusobia, which supported a monophylets within a paraphyletic Howardula.
Mitochondrial Phylogeography of Vegetable Pest Liriomyza sativae (Diptera: Agromyzidae): Divergent Clades and Invasive Populations
Phylogeographic analysis of mitochondrial cytochrome oxidase I sequence variation indicates that L. sativae harbors distinct mitochondrial clades suggestive of the presence of cryptic species, and two of the major mitochondrialClades exhibited polyphagy.

A fossil-calibrated molecular chronogram is used to compare the effects of a major biotic factor and a major abiotic factor on the macroevolutionary dynamics of a large Cenozoic radiation of phytophagous insects, the leaf-mining fly genus Phytomyza, and finds one of the first statistically supported examples of consistently elevated net diversification accompanying shift to new plant clades.
Hidden Neotropical Diversity: Greater Than the Sum of Its Parts
It is suggested that neotropical herbivorous insect diversity is not simply a function of plant taxonomic and architectural diversity, but also reflects the geographic distribution of hosts and the age and area of the neotropics.
Tracing the geographical origin of Megastigmus transvaalensis (Hymenoptera: Torymidae): an African wasp feeding on a South American plant in North America
It is concluded that M. transvaalensis was originally an African Rhus‐feeder that readily attacks Schinus, and implications of the results for biocontrol efforts against invasive Schinus populations are discussed.
Molecular Identification of Two Closely Related Species of Mealybugs of the Genus Planococcus (Homoptera: Pseudococcidae)
Results from maximum parsimony analysis of DNA sequence data from both genes indicate the existence of a third clade from the Hawaiian Islands, whose members are distinct from both P. citri and P. minor.
Molecular phylogeny and systematics of leaf‐mining flies (Diptera: Agromyzidae): delimitation of Phytomyza Fallén sensu lato and included species groups, with new insights on morphological and…
The large size of the Phytomyza lineage and an inferred pattern of host family‐specific species radiations make it a promising candidate for the study of macroevolutionary patterns of host shift and diversification in phytophagous insects.
