Figure 2 in Occurrence of the Ambrosia Beetle Xyleborinus exiguus (Walker) (Curculionidae: Scolytinae: Xyleborini) on the Island of Oʻahu, Hawaiʻi, USA
Figure 2. One of five most parsimonious trees found in an exhaustive search. The clade comprising individuals from Hawaiʻi and Papua New Guinea was unresolved in the strict consensus of the five most parsimonious trees. Numbers at nodes are bootstrap values (>90%) determined with 500 pseudo-replicates using branch and bound searches.

New non-native pseudocryptic Cyclorhipidion species (Coleoptera: Curculionidae: Scolytinae: Xyleborini) found in the United States as revealed in a multigene phylogeny
<p>Pseudocryptic species, those that are difficult to diagnose using traditional taxonomic methods, are serious impediments for recognizing the introduction of non-native species. Rapid identification of species facilitates a rapid response to newly introduced species which can lessen their damaging effects. This situation is acute for known pest species such as xyleborine ambrosia beetles which are difficult to identify given minute morphological, often variable, diagnostic characters. These beetles have been introduced into non-native temperate regions and have caused economic and ecological havoc. In this study, we produced DNA-based phylogenies using four genes for individuals of <em>Cyclorhipidion bodoanum</em> (Reitter, 1913)<em>, C. distinguendum </em>(Eggers, 1930), and <em>C. pelliculosum </em>(Eichhoff, 1878) sampled from their introduced and native Asian ranges and as well as other <em>Cyclorhipidion </em>species. In addition, we review subtle morphological characters for diagnostic potential for these similar species. Bayesian phylogenetic analysis produced well-resolved and supported phylogeny that provided evidence for multiple introductions of <em>C. bodoanum and C. distinguendum</em> into the US and the occurrence of pseudocryptic species. The ambrosia beetles <em>Cyclorhipidion tenuigraphum </em>(Schedl, 1953)<em> </em>and<em> C. nemesis </em>Smith & Cognato, sp. nov. are reported in North America for the first time. We find that the pattern of elytral interstrial setae is an unrealized source for the identification of <em>Cyclorhipidion</em> species. This study resulted in the recognition of six species adventive to the US with the revised status of <em>C. californicum</em> (Wood, 1975). All species known from North American are diagnosed, illustrated and a key is provided.</p>

FIGURE 8. A in New genera of Palaeotropical Xyleborini (Coleoptera: Curculionidae: Scolytinae) based on congruence between morphological and molecular characters
FIGURE 8. A morphology-based cladistic analysis of species previously placed in Amasa, Cyclorhipidion, Xyleborus, and similar species of unclear affiliation. Combinable-component consensus of 240 most parsimonious trees (60 steps). The large number of MP trees is almost entirely due to the lack of resolution among the terminal Amasa spp., illustrating the paucity of synapomorphic characters in these dubious species. Numbers at nodes indicate Bremer support.
