The Philodromus pulchellus species-group is defined and diagnosed. Eleven species are included, described or redescribed, keyed and illustrated: P. afroglaucinus, sp. nov. from Algeria; P. bistigma Simon, 1870, P. glaucinus Simon, 1870, P. lamellipalpis, sp. nov. from Algeria; P. medius O. P.-Cambridge, 1872; P. pardalis, sp. nov. from northern Africa and the Iberian peninsula; P. pulchellus Lucas, 1846, P. punctigerus O. P.-Cambridge, 1908, P. ruficapillus Simon, 1885, P. simoni de Mello-Leitão, 1929, and P. wunderlichi, sp. nov. from the western Canary Islands. The validity of P. bistigma and P. medius is re-established (formerly in synonymy with P. pulchellus); neotype and lectotype, respectively are newly designated. The following new synonymies are proposed: P. torquatus O. P.- Cambridge, 1908 = P. pulchellus; P. salinarum Denis, 1939 = P. glaucinus; P. glaucinoides Wunderlich, 1987 = P. punctigerus; P. marionschmidti (Schmidt, 1990) = P. pulchellus. Philodromus albopictus Simon, 1875 and P. rubidus Simon, 1870 are considered nomina dubia. Determination of phylogenetic relationships within the group is difficult owing to continuous character variation, resulting in partially incongruent reconstructions using morphological and molecular data (partial mitochondrial cytochrome c oxidase I gene). Dispersal vicariance analysis provides support for a western Mediterranean origin of the group.

A new species of the genus Cyrtodactylus is described from Dien Bien Province, northwestern Vietnam based on morphological and molecular data. Cyrtodactylus ngati sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 69.3 mm; dorsal pattern consisting of six dark irregular transverse bands between limb insertions; inter-supranasals one; dorsal tubercles present on occiput, body, hind limbs and on first half of tail; 17–22 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, with interspersed tubercles; 32–38 ventral scales between ventrolateral folds; 13 precloacal pores separated by a diastema of 5/5 poreless scales from a series of 7/7 femoral pores in enlarged femoral scales; precloacal and femoral pores absent in females; 1–3 postcloacal tubercles on each side; transversely enlarged median subcaudal scales absent. In the molecular analyses, the new species is shown to be the sister taxon to C. interdigitalis from Thailand. This is the 47th species of the genus Cyrtodactylus and the first member of the C. brevipalmatus species group recorded from Vietnam.

Twenty-nine species are recognized in the Orasema stramineipes species group, including 22 new species in what is now the most diverse species group of the New World ant-parasitoid genus Orasema Cameron. Orasema aenea Gahan syn. n. is synonymized with O. freychei (Gemignani), the holotype of which has been rediscovered. Orasema smithi Howard syn. n. is synonymized with Orasema minutissima Howard. Orasema violacea Gemignani syn. n. and its replacement name Orasema gemignanii De Santis syn. n. are synonymized with O. worcesteri (Girault). Twenty-two species are described as new: O. arimbome Dominguez, Heraty & Burks n. sp., O. carchi Heraty, Burks & Dominguez n. sp., and the following 20 species by Burks, Heraty & Dominguez: O. chunpi n. sp., O. cozamalotl n. sp., O. evansi n. sp., O. hyarimai n. sp., O. kaspi n. sp., O. kulli n. sp., O. llanthu n. sp., O. llika n. sp., O. mati n. sp., O. nyamo n. sp., O. pirca n. sp., O. pisi n. sp., O. qillu n. sp., O. qincha n. sp., O. rikra n. sp., O. taku n. sp., O. tapi n. sp., O. torrensi n. sp., O. woolleyi n. sp., and O. yaax n. sp. The stramineipes-group has much greater diversity in tropical America than outside the tropics, and is much more diverse than its sister-group, the susanae-group, which is mainly present in temperate regions of Argentina. A hypothesis of phylogenetic relationships is proposed based on an analysis of 28S-D2 rDNA and cytochrome oxidase I (COI) for 14 stramineipes-group species. Species concepts were established using both morphological and molecular data. Most species in the stramineipes-group have a tropical distribution, with only a few species in temperate regions. Ant hosts for the group include Pheidole Westwood, Wasmannia Forel, and possibly Solenopsis Westwood (Formicidae: Myrmicinae). Orasema minutissima is a common parasitoid of Wasmannia auropunctata Roger in the Caribbean and has the potential to be a biological control agent in other areas of the world. Two distinct size morphs are recognized for O. minutissima, which are correlated with attacking either Wasmannia (small morph) or different castes of Pheidole (medium to large size morphs). Some species of Orasema have been regarded as pests due to scarring or secondary infections of leaves or fruit of banana, yerba mate or blueberry, but outbreaks are rare and the threat is usually temporary.

Autolytinae is revised based on available types, and newly collected specimens. Out of 170 nominal species, 18 are considered as incertae sedis, 43 are regarded as junior synonyms, and 25 are referred to as nomina dubia. The relationships of Autolytinae is assessed from 51 morphological characters and 211 states for 76 ingroup-taxa, and 460 molecular characters from mitochondrial 16S rDNA and nuclear 18S rDNA for 31 ingroup-taxa; outgroups include 12 non-autolytine syllid polychaetes. Two analyses are provided, one including morphological data only, and one with combined morphological and molecular data sets. The resulting strict consensus tree from the combined data is chosen for a reclassification. Three main clades are identified: Procerini trib. n., Autolytini Grube, 1850, and Epigamia gen. n. Proceraea Ehlers, 1864 and Myrianida Milne Edwards, 1845 are referred to as nomen protectum, while Scolopendra Slabber, 1781, Podonereis Blainville, 1818, Amytis Savigny, 1822, Polynice Savigny, 1822, and Nereisyllis Blainville, 1828 are considered

Genetic Comparison

A new species of the genus Cyrtodactylus from Vientiane Province, northern Laos is described based on morphological and molecular data. Cyrtodactylus muangfuangensis sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 83.9 mm; dorsal pattern consisting of dark nuchal loop, nape band and five dark transversal bands between limb insertions; intersupranasals two; dorsal tubercles present on occiput, body, hind limbs and tail base; 15 or 16 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, without interspersed tubercles; 31–37 ventral scales between ventrolateral folds; six precloacal pores and 15 femoral pores in males, which are interrupted by six to eight poreless scales; six precloacal pitted scales plus in total 10–15 pitted femoral scales in females, which are separated by six to eight poreless scales; enlarged precloacal and femoral scales present; two or three postcloacal tubercles; median subcaudal scales transversely enlarged. In molecular analyses, the new species is strongly supported as a member of the Cyrtodactylus phongnhakebangensis species group, and weakly corroborated as a sister taxon to C. pageli. Pairwise genetic comparison shows that it is at least 18% divergent from other congeners in the species group based on a fragment of the mitochondrial cytochrome C oxidase subunit I gene.

Morphological And Molecular Data

The systematic status of Kaindipsocinae (formerly Kaindipsocini) is revised based on morphology of the male terminalia and on molecular data. The genera Clematostigma, Lasiopsocus and Tanystigma are newly assigned to this subfamily. The ‘Blaste’ lunulata species-group is also placed within Kaindipsocinae and is probably closest to Kaindipsocus. Both morphological and molecular data provide strong support for monophyly of Kaindipsocinae and molecular data support a sister relationship between this subfamily and the rest of Psocidae.

Incomplete Sampling

Many species and subspecies of Potamon have been described from the easternmost distribution of the genus in the western tributaries of the Indus River. Most of them were synonymised subsequently under the two names of currently valid species known from the region: Potamon gedrosianum Alcock, 1909 and Potamon ruttneri Pretzmann, 1962. Genetic and morphological information, based on mitochondrial 16S rDNA and the first male gonopod (G1), were gathered in the course of the present study. The corresponding results suggest the occurrence of four groups and question the taxonomic status of both species. We also revise the distribution range of both species, in particular that of P. gedrosianum, with a new record from Iran. Overall, the study reveals the need for a major revision using further morphological and molecular data. Because of the complexity of this necessary revision and the incomplete sampling, we here refrain from proposing any taxonomic conclusions.

We describe two new species of Tropidodipsas related to the T. fasciata species group as defined by Kofron (1987), and provide morphological and molecular data to support the novelty of both species. A partial molecular phylogeny of the Mexican species of snail-eating snakes (Serpentes, Dipsadidae) is presented, and we discuss evolutionary relationships as supported by our molecular results. We analyze specific relationships of the new species described herein with their closest relatives. We present a distribution map for all species of Tropidodipsas and include photographs of living individuals of each species. Finally, we discuss other taxonomic changes based on our molecular phylogeny as well as conservation priorities of the new species.

Both morphological and molecular data have been used to examine the taxonomical status of Carpesium linearibracteatum (Asteraceae). We determined that C. leptophyllum var. linearibracteatum is closer to C. szechuanense and C. triste than to C. longifolium, thus not agreeing with the synonymization of this taxon and C. longifolium. We propose to elevate C. leptophyllum var. linearibracteatum to the species level as C. linearibracteatum.

The mealybug genus Ferrisia Fullaway is revised to include 18 species, based on morphological and molecular data. Wedistinguish the widespread pest species F. virgata (Cockerell) from morphologically similar species and provide a reviseddescription and illustration for the adult female of F. virgata. We resurrect Dactylopius dasylirii Cockerell stat. rev. fromsynonymy with Dactylopius virgatus Cockerell as Ferrisia dasylirii (Cockerell) and apply this name to many North Amer-ican and Caribbean populations previously recognised as F. virgata; F. dasylirii is the most difficult to distinguish mor-phologically from F. virgata and exhibits morphological and molecular variation among some populations. We designatea lectotype for D. dasylirii Cockerell. Eight new species of Ferrisia are described and illustrated based on the adult female,and named as Ferrisia colombiana sp. n., F. cristinae sp. n., F. ecuadorensis sp. n., F. kondoi sp. n., F. milleri sp. n., F.pitcairnia sp. n., F. uzinuri sp. n. and F. williamsi sp. n. The relationships of five of these new species and five namedspecies are discussed in relation to a previously published phylogenetic tree that was based on nucleotide sequence data.Taxonomically informative morphological features (such as the size, shape and position of discoidal pores associated withthe dorsal enlarged tubular ducts and the ventral oral-collar tubular ducts), identified for each of the genetic groups (clades)on the tree, are used to help to diagnose the species. We also describe and illustrate the adult female of a form of F. gilliGullan, found on Magnolia and some other host plants, that has numerous clusters of small ventral oral-collar ducts onthe body margins. For seven named species—F. claviseta (Lobdell), F. malvastra (McDaniel), F. meridionalis Williams,F. multiformis Granara de Willink, F. quaintancii (Tinsley), F. setosa (Lobdell) and F. terani Williams & Granara de Will-ink—we provide revised illustrations of the adult females as well as diagnostic morphological notes and information ondistribution and host plants. We also recognise Eurycoccus copallinae Ferris as a junior synonym (syn. n.) of Dactylopiusquaintancii Tinsley (now F. quaintancii) and designate a lectotype for E. copallinae. We include photographs of the liveappearance of the adult females of six Ferrisia species and also a key to all known species of Ferrisia based on the mor-phology of the adult females. We transfer the species currently known as Ferrisia floridana (Ferris) to a new monotypicgenus, Pseudoferrisia gen. n., as Pseudoferrisia floridana (Ferris) comb. n., and provide a description of the genus and its type species (Ferrisiana floridana Ferris), as well as a new illustration of the adult female.

The new genus Luthela gen. nov. is erected based on morphology and molecular data of the type species Luthela yiyuan sp. nov. A taxonomic revision of the new genus is given. Three Sinothela species are transferred to the new genus, L. luotianensis comb. nov. and L. schensiensis comb. nov. are redescribed using our newly collected specimens, include L. heyangensis comb. nov. as a junior synonym of L. schensiensis comb. nov., and describe six new species based on both male and female morphological characters: L. badong sp. nov., L. dengfeng sp. nov., L. handan sp. nov., L. taian sp. nov., L. yiyuan sp. nov., and L. yuncheng sp. nov.
