Psychotria subg. Heteropsychotria Steyerm. has been shown by morphological and molecular analyses to be polyphyletic. Most of its species, including its type, belong to Palicourea Aubl. (“Pal.”). Thirty-two species of this group are reviewed here, and 17 species in Psychotria L. are transferred to Palicourea and one to Rudgea Salisb. Two replacement names, Pal. agudeloana C. M. Taylor and Pal. tabayensis C. M. Taylor, are published. Taxonomic studies here clarify circumscriptions of similar, often-confused species for several distinctive species groups found variously in Mesoamerica and the Andes: the Palicourea aschersonianoides group, the Palicourea galeottiana group, the Palicourea sulphurea group, and the Palicourea tristis group. Three new species of Palicourea are described: Pal. aschersonianula C. M. Taylor, Pal. gonzaleziana C. M. Taylor, and Pal. wachterae C. M. Taylor. Nineteen names are newly typified, and infrageneric classifications are noted for the species of Palicourea studied.

Three New Species

The type species of Mischonyx Bertkau 1880, Mischonyx squalidus, was described based on a juvenile. The holotype is lost. Based on a revision of publications, the genus includes 12 species, all in Brazil. The objectives of this research are: to propose a phylogenetic hypothesis for Mischonyx based on Total Evidence (TE); propose taxonomic changes based on the phylogeny; and analyze the phylogenetic hypothesis biogeographically. Using the exemplar approach to taxon selection, we studied 54 specimens, 15 outgroups and 39 ingroup taxa using seven molecular markers (28S, 12S and 16S ribosomal genes, citochrome oxidase subunit I gene, carbamoyl-phosphate synthetase gene, internal transcribed spacer subunit 2 and histone H3 gene), totaling 3,742 bp, and 128 morphological characters. We analyzed the dataset under three optimality criteria: Maximum likelihood (ML), Maximum parsimony (MP) and Bayesian. We discuss the transformation of character states throughout the phylogeny, the different phylogenetic hypotheses using different datasets and the congruence of evidence between the clades obtained by the phylogenetic analysis and the biogeographical hypothesis for the Atlantic Forest areas of endemism. We estimate that Mischonyx clade diverged 50.53 Mya, and inside the genus there are two major clades. One of them cointains species from Paraná, Santa Catarina, South of São Paulo and Serra do Mar Areas of Endemism and the other has species from Espinhaço, Bocaina, South coast of Rio de Janeiro and Serra dos Órgãos Areas of Endemism. The first split inside these two clades occurred at 48.94 and 44.80 Mya, respectively. We describe three new species from Brazil: Mischonyx minimus sp. nov. (type locality: Petrópolis, Rio de Janeiro), Mischonyx intervalensis sp. nov. (type locality: Ribeirão Grande, São Paulo) and Mischonyx tinguaensis sp. nov (type locality: Nova Iguaçu, Rio de Janeiro). The genus Urodiabunus Mello-Leitão, 1935 is considered a junior synonym of Mischonyx. Weyhia spinifrons Mello-Leitão, 1923; Weyhia clavifemur Mello-Leitão, 1927 and Geraeocormobius reitzi Vasconcelos, 2005 were transferred to Mischonyx. Mischonyx cuspidatus (Roewer, 1913) is a junior synonym of M. squalidus Bertkau, 1880. In the results of the phylogenetic analyses, Gonyleptes antiquus Mello-Leitão, 1934 (former Mischonyx antiquus) does not belong in Mischonyx and its original combination is re-established. As it is now defined, Mischonyx comprises 17 species, with seven new combinations.

Three New Species

Australian mites in the genus Asca were last reviewed in 1956 when the first three Australian species were described. We here provide diagnoses for those species, describe three new species (Asca macromela, A. grostali and A. mindi) from the leaves of rainforest trees, and report on the occurrence in Australia of a species described from New Zealand (A. porosa Wood) and of a cosmopolitan thelytokous species (A. garmani Hurlbutt). Keys to the eight species and the three species-groups they represent are provided. Examination of 13 266 leaves from 193 species of woody plants in eastern Australian forests indicated that Asca mites are abundant and diverse inhabitants of tropical rainforest canopies, but decline in both diversity and abundance with increasing latitude.

The Agrilus purpurifrons species-group comprising twelve species from the Oriental region is defined and revised. A key to species is provided and complemented with illustrations of habitus and genitalia. Three new species are described: Agrilus cameronius sp. nov. (Malaysia); A. puncak sp. nov. (Indonesia); and A. vendibilis sp. nov. (Indonesia). The following taxonomic changes are proposed: the specific names lacroixi Obenberger, 1936 syn. nov. and chapaensis Descarpentries & Villiers, 1967 syn. nov. are junior synonyms in the synonymy of A. morio Kerremans, 1895; the name rousselatae Baudon, 1968 stat. rev. is removed from the synonymy of A. lacroixi Obenberger, 1936 and revalidated as the specific name of A. rousselatae Baudon, 1968.

Three New Species

An inventory of Phlebotomine sandflies was carried out in the Ankarana tsingy located in far northern Madagascar. A total of 723 sandflies were used for morphological, morphometric, and molecular studies (sequencing of partial cytochrome B (mtDNA) and partial 28S (rDNA)). Nine species were identified: Phlebotomus fertei, Sergentomyia anka, Se. sclerosiphon, Se. goodmani, two species of the genus Grassomyia, as well as three new species described herein: Se. volfi n. sp., Se. kaltenbachi n. sp., and Se. ozbeli n. sp. The recognition of these new species is strongly supported by molecular analyses. The first two of the new species could not be classified into any existing subgenus, therefore we proposed two new subgenera (Ranavalonomyia subg. nov., and Riouxomyia subg. nov.), with combinations as: Sergentomyia (Ranavalonomyia) volfi and Sergentomyia (Riouxomyia) kaltenbachi. Our study reveals important molecular variability in Se. anka, with the recognition of a population whose taxonomic status remains below that of species. Our research confirms the need to further study the specific diversity of Malagasy sandflies, which until the start of this millennium remained mostly unknown.

Three New Species

An integrative taxonomic analysis of the Ptychozoon lionotum group across its range in Indochina and Sundaland recovers P. lionotum sensu lato Annandale, 1905 as paraphyletic with respect to P. popaense Grismer, Wood, Thura, Grismer, Brown, & Stuart, 2018a and composed of four allopatric, genetically divergent, ND2 mitochondrial lineages. Multivariate and univariate analyses of continuous and discrete morphological and color pattern characters statistically and discretely diagnose each lineage from one another and together, with maximum likelihood and Bayesian inference analyses, provide the foundation for the recognition of each lineage as a new species—hypotheses corroborated with a Generalized Mixed Yule Coalescent species delimitation analysis. Ptychozoon cicakterbang sp. nov. ranges throughout Peninsular Malaysia to Pulau Natuna Besar, Indonesia; P. kabkaebin sp. nov. is endemic to northern and central Laos; and P. tokehos sp. nov. ranges from southern Thailand south of the Isthmus of Kra northward to Chiang Mai, fringing the Chao Phraya Basin and ranging southward through Cambodia to southern Vietnam. Ptychozoon lionotum sensu stricto ranges from northwestern Laos through southern Myanmar to eastern India. The phylogeographic structure within each species varies considerably with P. lionotum s.s. showing no genetic divergence across its 1,100 km range compared to P. cicakterbang sp. nov. showing upwards of 8.2% sequence divergence between syntopic individuals. Significant phylogeographic structure exists within P. tokehos sp. nov. and increased sampling throughout Thailand may require additional taxonomic changes within this species.

Maxillary Dentition

Dipsadine snakes of the genus Atractus are endemic to the Neotropical region, occurring from Panama to Argentina. Currently, the taxonomic status of most species of the genus is unclear and previous attempts of taxonomic revisions have been local in scale. In this paper we evaluate the taxonomic status of the Brazilian Atlantic Forest species of Atractus based on meristic, morphometric, maxillary dentition, and hemipenis characters. Quantitative and qualitative analyses suggest the recognition of one new species (A. caete sp. nov.) from the state of Alagoas, another (A. francoi sp. nov.) from the mountainous regions of the states of Rio de Janeiro and São Paulo, and the synonymy of A. kangueryensis with A. thalesdelemai. Specimens previously assigned to A. taeniatus in Argentina and Brazil are here considered A. paraguayensis. A key to the Atlantic Forest Atractus is provided and three new species groups are proposed for some cisAndean Atractus, mainly on the basis of hemipenial morphology: the A. emmeli, A. maculatus, and A. pantostictus species groups.

Pirate spiders (Mimetidae) are well known for their specialised feeding ecology. They are vagrant araneophagic predators, enter the webs of their prey spiders and exhibit patterns of aggressive mimicry to overcome the web owner. The mimetid fauna of Australia and New Zealand currently consists of 26 species in the following three genera: Australomimetus Heimer, 1986 (18 species), Mimetus Hentz, 1832 (six species), and Ero C.L. Koch, 1836 (two species). The systematic position of the majority of Australasian mimetids was investigated through phylogenetic techniques utilising morphological character systems of 29 exemplar taxa and 87 characters, including the first examination of spinneret structure in species of Australomimetus. The results support an expanded concept for Australomimetus, which, apart from the introduced Ero aphana (Walckenaer, 1802), is found to contain the entire Australian and New Zealand mimetid fauna, also recorded from Asia. The following taxonomic changes are proposed: A. catulli (Heimer, 1989), comb. nov., A. hannemanni (Heimer, 1989), comb. nov., A. japonicus (Uyemura, 1938), comb. nov., A. mendicus (O. P. Cambridge, 1879), comb. nov. and A. sennio (Urquhart, 1891), comb. nov.; Ero luzoniensis Barrion & Litsinger, 1995 is synonymised with Ero aphana, and A. andreae Heimer, 1989 is synonymised with A. daviesianus Heimer, 1986; Mimetus tikaderi Gajbe, 1992 from India is excluded from Mimetidae, and referred to Liocranidae. The Western Australian mimetid fauna is described for the first time and comprises nine species of Australomimetus, including the following five new species: A. diabolicus, sp. nov., A. djuka, sp. nov., A. dunlopi, sp. nov., A. nasoi, sp. nov. and A. stephanieae, sp. nov. Several species-groups of Australomimetus are identified.
