Taxonomic Studies

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

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.

A New Species

The genus Minagenia Banks, 1934 is reported for the first time from Australia. A new species, M. lasallei Decker, Rodriguez & Pitts, sp. nov. (Australia: from Queensland to Tasmania), is described and illustrated. A key to the four species from the Australasian and Oriental regions is given. Three species are removed from Asian Minagenia: granulosa Tsuneki, 1989, comb. nov., to the genus Priocnemis Schiødte, 1837; pempuchiensis Tsuneki, 1989, comb. nov., to the genus Nipponodipogon Ishikawa, 1965; and assimilis Smith, 1861, comb. nov., to the genus Dichragenia Haupt, 1950. Minagenia alticola Tsuneki, 1989 is a member of an undescribed genus. Placement of this species is maintained in Minagenia until the new genus can be described in a future work. Minagenia brevicornis (Banks, 1934) is redescribed.

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.

A comprehensive revision of the genus Thouarella is presented. Thirty-five holotypes of the 38 nominal Thouarella species, two varieties, and one form were examined. The number of original Thouarella species has been reduced to 25, mostly through synonymy or new genus combinations. In the process several new species have also been identified, one of which is described here as Thouarella parachilensis nov. sp. The genus is split into two groups based on polyp arrangement: Group 1 with isolated polyps and Group 2 with polyps in pairs or whorls. An illustrated dichotomous key and detailed character table of the 25 Thouarella species are presented alongside an up-to-date account of all species described in the 19th and 20th centuries and summaries of the few described from 2000 onwards. We propose that Thouarella longispinosa is synonymous with Dasystenella acanthina, T. versluysi with T. brucei, and, T. tenuisquamis, T. flabellata, and T. carinata are synonymous with T. laxa. Lastly, we propose that T. bayeri and T. undulata be placed in Plumarella and support recent suggestions that T. alternata, T. recta, T. superba, and T. diadema are also Plumarella.
