The morphological and the combined matrices analyzed with TNT yielded a single most parsimonious cladogram that allows recognition of two main lineages within the Pantomorus-Naupactus complex in North and Central America. One is represented by the species formerly placed in Phacepholis and the Pantomorus species group II sensu Sharp, ranging along the Pacific coast of Central America and Mexico and reaching the Great Plains of North America in the United States, yet not occurring in South Amferica. The other lineageis represented by the species of Naupactus and Pantomorus species group I, with closer relationships to the South American species of these genera. The Pantomorus group I includes the type species of the genus (P. albosignatus Boheman) whereas the Pantomorus group II includes the type species of Athetetes Pascoe, 1886 (A. globicollis Pascoe). Based on the results of our phylogenetic analysis, we recommend retaining the name Pantomorus Schoenherr for most species of the Pantomorus group I, except P. stupidus (Boheman) and P. fem-oratus Sharp which should be transferred to Naupactus Dejean. Moreover, we enlarge the previous concept of Phacepholis to include most species of the Pantomorus group II, and we establish the synonymy oi Athetetes Pascoe, 1886with Phacepholis Horn, 1876, being the latter the valid name, by priority.

The male of Downeshelea cebacoi (Lane & Wirth) is redescribed and illustrated and the distribution of this species is now restricted to Panama and Costa Rica. In their revision of the Ceratopogonini of the world, Wirth and Grogan (1988) placed the species of the Monohelea multilineata group in the new genus Downeshelea, which includes 33 species worldwide (Borkent, 2009). Borkent and Spinelli (2000, 2007) listed 18 species from the Neotropical Region and Felippe-Bauer and Silva (2008) subsequently described D. oliveirai Felippe-Bauer from northem Brazil. Seven of these 19 species were originally described from Brazil and two others, D. cebacoi (Lane & Wirth) and D. guianae (Wirth), were reported as occurring in northem Brazil (Para state). With the addition of the new species described here, there are now 10 species knownfrom Brazil and 20 from the entire Neotropical Region.

查看更多>>摘要：The mitochondrial DNA control region (mtDNA CR) has been cloned and sequenced from 56 individuals representing five species of the genus Gampsocleis. The Neighbor-Joining (NJ) tree under the Kimura 2-parameter (K2P) model, G sedakovii haplotypes cluster into two distinct clades A and B. It suggests there may be more than one species within this group. The macropterous species, G. sinensis grouped among G. ussuriensis. Two brachypterous species, G. carinata and G. gratiosa grouped as sibling species.Individuals of G. carinata and G gratiosa grouped together in distinct clades, even when collected from different localities. MtDNA CR stmctural analysis found two conserved motifs in the primary sequences "(TA)n" and poly-A stretch in the twelve ensiferan species examined, which may be involved in mtDNA transcription or replication control.

A comparison between Domene lusitanica n. sp.and the other species of the Iberian endemic subgenus Lathromene is made using diagnostic characters. An identification key for the males of Lathromene species is presented, and biogeographical and ecological comments are also included. The species of Domene known from the Iberian Peninsula are listed and their distributions are mapped.
