Abstract
Phylogenetic relationships of the braconid wasp genus Yelicones Cameron are studied using the D2-D3 region of the nuclear 28S rRNA gene, both alone and simultaneously with morphology. The results support a morphology-based phylogeny, pre- sented elsewhere, with Yelicones being divided into two major groups corresponding to the New and Old World faunas. The African and Asian species largely form separate clades except for Yelicones wui Chen & He from China which is associated with the Afro- tropical species. Potential molecular synapomorphies are illustrated.
Highlights
Yelicones Cameron is a cosmopolitan and highly distinctive genus of parasitic rogadine braconid wasps
Parsimony analysis of 28s rRNA sequence data based on 564 alignable base pairs resulted in 2 most parsimonious trees (MPTs), the strict consensus of which is shown in Fig. 1A
Our molecular-based phylogeny supports the phylogeny based on morphological characters and indicated that Yelicones species are divided into 2 large clades, the Old World (OW) and New World (NW) species groups
Summary
Yelicones Cameron is a cosmopolitan and highly distinctive genus of parasitic rogadine braconid wasps. The genus was known for many years after its original description (Cameron, 1887) from only a few specimens collected in the Neotropics (Shenefelt, 1975). Over the last 40 or so years, many more species have been described, extending the known range to the IndoAustralian (including Oceania), Afrotropical, East Palaearctic and Oriental regions [Fischer, 1961, 1962 (as Pectenopius Fischer, a junior synonym of Yelicones); Togashi, 1980; Papp, 1985, 1989, 1991, 1992; Belokobylskij, 1993a,b; Quicke & Kruft, 1995; Chen & He 1997; Quicke et al, 1996, 1997, 1998; Quicke & Chishti, 1997; Areekul & Quicke, 2002; Areekul & Quicke, 2004a,b, in press a]. The genus is known to be widely distributed throughout the Old and New Worlds and has recently been recorded from the West Palaearctic (Spain: Shaw, 1998)
