Title: Review of the leafhopper genus Thaia Ghauri and related genera (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini)
The leafhopper genus Thaia Ghauri, 1962 and two related genera, Parathaia Kuoh, 1982 and Pseudothaia Kuoh, 1982, are revised. Nlunga Dworakowska, 1974, previously treated as a subgenus of Thaia, is elevated to the genus level, and Parathaia Kuoh, 1982, previously treated as a synonym of Thaia, is reinstated to valid status. The Oriental species lacking foveae on the pronotum are excluded from Nlunga and transferred to a new genus, Etmaria gen. n. Two species, Pseudothaia caudata Song & Li, 2013 and Thaia (Nlunga) leishanensis (Song & Li, 2007), are treated as Incertae sedis within Erythroneurini. Moreover, nine additional new species are described and illustrated: Nlunga parareeneni, Etmaria brevis, E. chaiyaphumica, E. dentata, E. indonesica, E. magna, E. triquetra, E. ulterior and Pseudothaia forcipis spp. nov. more »« less

The Mexican leafhopper genus and species Devolana hemicycla DeLong, 1967 syn. nov., is recognized as a junior synonym of Usanus stonei DeLong, 1947. Three previously described species, U. tuxcacuensis (Pinedo-Escatel & Aguilar-Pérez, 2019) comb. nov., U. youajla (Pinedo-Escatel, 2019) comb. nov., and U. xajxayakamej (Pinedo-Escatel, 2019) comb. nov. are transferred to Usanus. Two new species, U. xochipalensis sp. nov. and U. igualaensis sp. nov. from Guerrero, are described and illustrated. An updated key to all known species of Usanus is provided.

Because of the problematical identity and status of the type of the xeniid soft coral genus Cespitularia Milne-Edwards & Haime, 1850, the species C. stolonifera Gohar, 1938 is revised. Examination of the type colonies has led to the establishment of the new genus Unomia gen. n. which is described and depicted. This genus features a stalk, commonly divided into branches featuring a diffuse polypiferous part consisting of distal clustered polyps and proximal individual ones on the stalk or the basal membranous part of the colonies. The sclerites are ellipsoid platelets composed of dendritic calcite rods whose tips are distinct on the surface of the platelets. Freshly collected material from Venezuelan reefs where the species is invasive was subjected to molecular phylogenetic analysis, the results of which substantiate the taxonomic assignment of the new genus under U. stolonifera comb. n. A new species, U. complanatis, from Japan and Green Island (Taiwan) is described and further illustrates the extent of the interspecific morphological variation within the genus. The results reveal that the biogeographic distribution of Unomia gen. n. includes Pacific Ocean reefs in addition to the previously reported invaded Caribbean reefs.
We describe a new species of frog of the genus Platymantis Günther (subgenus Tirahanulap), from the east-central regions of the Philippines. It belongs to the the previously-defined P. hazelae Group) based on morphological and bioacoustic datasets. The new species is phenotypically and ecologically most similar to members of Tirahanulap, an assemblage of small-bodied arboreal frogs inhabiting montane forests of the central and northern islands of the Philippine archipelago. The new species represents the first taxon in the Cloud Frog species known from the biogeographically unique Mindanao Pleistocene Aggregate Island Complex. Particularly susceptible to local extirpation following deforestation, all known species of Tirahanulap are important indicator species for environmental and conservation assessments, making this new species not only an exceptional addition to Philippine biodiversity but also an important symbol for conservation initiatives in the region.
Two new species of the cestode genus Caulobothrium, collected from the duckbill eagle ray, Aetomylaeus bovinus, off Senegal, are described. Although postulated as sister taxa in an earlier molecular phylogenetic analysis, Caulobothrium multispelaeum n. sp. and Caulobothrium katzi n. sp., respectively, are among the smallest and largest members of the genus. The smaller species is unique among its congeners in possessing unusual medial longitudinal grooves along the dorsal and ventral surfaces of its strobila that develop into a tandem series of elliptical apertures on the posterior proglottids. The inner surfaces of these apertures stained positively with McManus’ periodic acid Schiff in a manner similar to that seen in members of the distantly related lecanicephalidean genus Elicilacunosus. The larger species differs from its congeners in size, number of proglottids, and arrangement of bothridial loculi. Both new species were found to possess a small apical sucker on the anterior margin of each of their bothridia. Scanning electron microscopy (SEM) and frontal sections of a bothridium of Caulobothrium tetrascaphium suggests that this species also bears an apical sucker. Examination of the hologenophore of the species provisionally referred to as Caulobothrium n. sp. 5 in the earlier molecular analysis indicates it is conspecific with the recently described Caulobothrium pedunculatum, which was also determined to possess bothridial apical suckers. This leads us to suspect that this feature may be found to occur in all members of the genus. SEM of specimens of Caulobothrium for the first time indicates their bothridial surfaces are covered with filitriches of various sizes but lack spinitriches; spinitriches were seen only on the cephalic peduncle of C. katzi n. sp. The geographic distribution and host associations of Caulobothrium are expanded to include data now available for all species. The diagnosis of the genus is revised to include all of this information.
Five new species of the endemic Australian leafhopper genus Mayawa Fletcher, 2000 (M. affinifacialis sp. nov., M. bimaculata sp. nov., M. brevicephala sp. nov., M. kathyae sp. nov. and M. vestigia sp. nov.) are described and illustrated and a revised key to species is provided. One of the new species tested positive for a previously unknown strain of phytoplasma belonging to the 16SrV group. The related paralimnine genus Austroauridius gen. nov. based on A. iwaii sp. nov. from Queensland is also described and illustrated and a key to known genera of Australian Paralimnini is provided.
