“…Trichadenotecnini, Li, 2002, a new junior synonym of Ptyctini Mockford, 1993 Type genus of Trichadenotecnini: Trichadenotecnum Enderlein, 1909. As clearly shown in the present analyses, two trichadenotecnini genera Trichadenotecnum based on some stable morphological data (Mockford, 1993;Yoshizawa et al, 2007;Yoshizawa et al, submitted). Trichadenotecnum, the type genus of Trichadenotecnini, forms well supported clade which is deeply divergent from the other genera.…”

“…Some clades can be recognized within Ptyctini (Fig. 2); however, except for the strongly supported Copostigma-Ptycta complex (Yoshizawa & Smithers, 2006;Bess & Yoshizawa, 2007) and the fairly well supported Psocidus-Indiopsocus clade, inter-generic relationships of ptyctini genera are nearly unresolved. Because dense taxon sampling is critical for the accuracy of phylogenetic estimation (Graybeal, 1998), inclusion of additional genera or additional species of some poorly sampled genera (e.g., Camelopsocus and Atlantopsocus) may improve the resolution of deep branches.…”

“…Monophyly of Ptyctini was not recovered by any analysis and was also rejected by the AU test (P=0.025, CI=48.3). Some clades were recognized within Ptyctini but, except for the Copostigma-Ptycta complex (100% by all analyses:Bess & Yoshizawa, 2007) and Indiopsocus-Psocidus (s.str.) clade (100% PP, 55-60% bootstrap), deep inter-generic relationships within Ptyctini were poorly supported.The tribes Psocini, Cerastipsocini and Metylophorini always composed a monophyletic group, together with the subfamily Thyrsophorinae.…”

We evaluated the higher level classification within the family Psocidae (Insecta: Psocodea: 'Psocoptera') based on combined analyses of nuclear 18S, Histone 3, wingless and mitochondrial 12S, 16S and COI gene sequences. Various analyses (inclusion/exclusion of incomplete taxa and/or rapidly evolving genes, data partitioning, and analytical method selection) all provided similar results, which were generally concordant with relationships inferred using morphological observations. Based on the phylogenetic trees estimated for Psocidae, we propose a revised higher level classification of this family, although uncertainty still exists regarding some aspects of this classification. This classification includes a basal division into two subfamilies, 'Amphigerontiinae' (possibly paraphyletic) and Psocinae. The Amphigerontiinae is divided into the tribes Kaindipsocini (new tribe), Blastini, Amphigerontini, and Stylatopsocini. Psocinae is divided into the tribes 'Ptyctini' (probably paraphyletic), Psocini, Atrichadenotecnini (new tribe), Sigmatoneurini, Metylophorini, and Thyrsophorini (the latter includes the taxon previously recognized as Cerastipsocini). We examined the evolution of symmetric/asymmetric male genitalia over this tree and found this character to be quite homoplasious.

“…The genus Ptycta includes more than 170 species from all zoogeographical regions of the world, with the greatest diversity in subtropical and tropical regions of Africa (29 species), Asia (43 species) and the Pacific Islands (63 species) (Lienhard & Smithers, ; Bess & Yoshizawa, ). The genus was erected by Enderlein () to include two Hawaiian species – the type species Psocus haleakalae Perkins, 1899 and Psocus distinguendus Perkins, 1899 – and the Indonesian species Clematostigma schillei Enderlein, 1906.…”

Aim The use of intuitive or explicit biogeographical reconstruction techniques to estimate the timing of species radiations on the Hawaiian Islands, while often incorporating evidence on the timing of island formation, may be misleading if the effects of extinction are overlooked. Using phylogenies of the bark louse genus Ptycta (Psocidae), we compared results from biogeographical character mapping with those from molecular dating analyses. These results were used to evaluate the 'progression model', which predicts an oldest-toyoungest pattern of island colonization.Location The main Hawaiian Islands (Kauai, Oahu, Maui, Lanai, Molokai and Hawaii).Methods With a data set including 101 Hawaiian Ptycta specimens and 18 outgroup species, we constructed molecular phylogenies based on sequences of the nuclear gene wingless and mitochondrial genes 12S, 16S and cytochrome c oxidase subunit I (COI). Maximum-likelihood, maximum-parsimony and Bayesian phylogenetic analyses were used. We used beast to estimate a timecalibrated tree under a relaxed clock model. ResultsOur analyses suggested a single colonization event, followed by extensive movement of Ptycta among islands and species radiations within and between islands. This monophyletic radiation is composed of two wellsupported clades that are also supported by two synapomorphic characters of the male genitalia.Main conclusions Very different biogeographical patterns are inferred by molecular dating versus approaches based on character mapping. Simple biogeographical reconstruction over the molecular phylogeny supports a pattern of youngest-to-oldest island colonization, the reverse of that predicted by the 'progression model', and implies that this radiation could be as young as the most recent islands of Maui (1.4 Ma) or Hawaii (0.5 Ma). Molecular dating, however, infers a pattern consistent with oldest-to-youngest island colonization, and suggests a lineage age of 7.1 Ma. Extinction on the oldest island of Kauai may account for the differences in results between the two analyses.

“…These last three genes have been extensively sampled in previous studies of the Psocidae phylogeny (e.g. Yoshizawa, 2001Yoshizawa, , 2004Bess and Yoshizawa, 2007;Yoshizawa and Johnson, 2008;Bess et al 2014). Additionally, the gene sequences of two outgroup free living lice species in the Hemipsocidae (Hemipsocus chloroticus) and Psilopsocidae (Psilopsocus malayanus) were sampled from publicly available databases.…”

Despite tropical psocids comprise ~60% of species diversity within the Psocidae (Insecta, Psocodea), previous studies on the Psocidae phylogeny have poorly sampled tropical species (<40% species in trees). Here we discuss the evolution and systematics of the Psocidae based on the most comprehensive species-level sampling of the Psocidae. We sequenced and inferred the phylogenetic position of 43 previously unsampled Neotropical species from COI, H3, WNT, 18S, 16S, and 12S. Based on our phylogenies we found that Neotropical psocids are generally not closely related to morphologically similar taxa in the Holarctic region. Consequently, the monophyletic status for the major groups within Psocidae (subfamilies and tribes) is recovered only when Holarctic groups are sampled (7–10 of 11 higher-level groups are monophyletic) but violated when Neotropical species are included in the dataset (1 of 11 higher-level groups are monophyletic). Leveraging the largest phylogeny of the Psocidae, our study pinpoints the downfalls of simply extending taxonomic knowledge from lineages of a certain area to inform diversity and evolution of lineages in other regions.HighlightsTropical psocids comprise >60% of the extant family richnessPrevious phylogenies have undersampled Tropical psocidsHolarctic and Neotropical species are classified under the same morphological groupsHolarctic and Neotropical generally correspond to evolutionarily distinct lineagesPhylogenies based on Holarctic psocids poorly inform evolution in the Neotropics
