Two New Species

Bottapotamon chenzhouense sp. n. and B. luxiense sp. n. are described from Hunan Province and Jiangxi Province, respectively. These species both have diagnostic features of the genus Bottapotamon and discernible characteristics as new species. B. chenzhouense sp. n. can be distinguished from co-geners by features such as the G1, which has a fold covering the surface of the entire subterminal article with a distal region. B. luxiense sp. n. has an elliptical carapace, and a sturdy and blunt terminal article of G1. The molecular phylogeny and biogeography of the genus Bottapotamon (Decapoda: Brachyura: Potamidae) were studied, using mitochondrial cytochrome oxidase I (mtDNA COI), 16S rRNA and nuclear histone H3 gene fragments. The results support the assignment of the two new species to the genus Bottapotamon. In addition, the divergence time of the genus Bottapotamon was estimated to be 3.49–1.08 Ma, which coincided with various vicariant and dispersal events that occurred in the geological area where the genus Bottapotamon is commonly distributed. Mountains appear to have played an important role in the distribution of this genus. The Wuyi Mountains gradually formed offshore and inland of southeastern China by the compression of the Pacific plate and the Indian plate in the Neogene-Quaternary, and the Luoxiao Mountains formed continuously in the continued forming in the north-south direction because of neotectonic movement, have resulted in the geographical distribution pattern of the genus Bottapotamon, which was also established gradually.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

AbstractThe genera Haida Keen and Pseudohaida Hatch are revised and transferred from the tribe Coryphiini to the Anthophagini; the Palearctic genus Eudectus Redten bacher is also placed in the Anthophagini. Eudectus crassicornis LeConte is transferred to the new gents Eudectoides. Two new species are described, Haida bisulcata from the Sierra Nevada in California and H. insulcata from Oregon. Pseudohaida ingrata Hatch is transferred to Subhaida Hatch, a member of the tribe Coryphiini.The mouthparts and antenna are illustrated for each genus and the male aedeagus for each species. A key is included to aid in the identification of all the included taxa.

Two New Species

Recent survey work for planthoppers at La Selva Biological Station in Costa Rica found two new species allied with Cenchrea Westwood. The cytochrome c oxidase subunit I (COI) and 18S were sequenced for the new taxa and used these data to assess the genus-level standing of the new taxa. The new taxa do not cluster with Cenchrea dorsalis Westwood, the type species of Cenchrea. A new genus Tico gen. n. described for the reception of new species described as Tico emmettcarri sp. n. (the type species) and Tico pseudosororius sp. n. Cenchrea sororia Fennah is moved to Tico gen. n., to form the new combination Tico sororius (Fennah). Tico gen. n. is compared with allied genera, and review genus-level diagnostic features and the species composition of Cenchrea, which appears to be compositionally heterogenous, but additional data is needed to evaluate genus-level placement of most species.
