A New Species

We describe and illustrate a new species of Beilschmiedia, from the Osa Peninsula of Costa Rica. It is distinguished by its small flowers, which are turbinate to campanulate, with six fertile stamens and pubescent ovary, in addition it has alternate leaves along the twigs, with the lower leaf surface glabrous and not glaucous. In the field, it can be recognized by its stature, a very large tree, with the bark reddish, and peeling in large plates. Among described congeners it is superficially similar to B. hexanthera, from French Guiana, which also has six fertile stamens, and staminodes of whorl III columnar, but differs in having a pubescent ovary and larger, more branched inflorescences.

Iucn Criteria

A new species of Glossoloma is described from the western Andean slopes of the Pichincha Province in northern Ecuador. Glossoloma wiehleri J.L.Clark & Tobar is differentiated from all other congeners by an epiphytic habit, elongate scandent shoots that exceed four meters in length, and coriaceous leaves with a velutinous indument on the lower leaf surface. The new species is illustrated, featured with field images from recent expeditions, and assigned the category of Endangered (EN) according to IUCN Criteria.

A New Species

Based on differences in hemipenial morphology we recognize two species of anoles related to Anolis polylepis: Anolis polylepis (Pacific versant of central and southern Costa Rica and western Panama, excluding the Osa Peninsula) and a species described herein which is restricted to the Osa Peninsula. The two species differ in hemipenial morphology (hemipenis bilobed in A. polylepis versus unilobed in the species from the Osa Peninsula) but show no discernable differences in external morphology (i.e., morphometrics, scalation, coloration, male dewlap). We therefore consider them to be cryptic species. At the neck of the Osa Peninsula where the ranges of the two species meet we detected a narrow (about 1 km wide) hybridization zone in which only individuals with an intermediate hemipenial morphology occur.

The new species Dorstenia marijanmatokii from Rwanda is described. It differs from Dorstenia nyungwensis in the discoid and entirely purple receptacle with shorter primary appendages and more numerous and irregular secondary appendages, and the densely tomentose lower leaf surface with purple venation. First records of Dorstenia brownii and D. psilurus from Rwanda and a key to the species of Dorstenia for Rwanda are provided.

A new vagrant species of Diptilomiopidae mite, in the Diptacus Keifer, 1951 genus, namely Diptacus rubuscolum sp. nov., living on the lower leaf surface of blackberry-Rubus sp. (Rosaceae) in South Brazil, is described and illustrated. In addition, Acalitus orthomerus Keifer, 1951, for the first time reported in Brazil and even in South America; a supplementary description of this species is presented based on females, males and immature specimens associated to the drupelets. Main morphological differences distinguishing the new Diptacus species and A. orthomerus species from those belonging to the same genera or morphologically similar also associated with Rubus are presented.

Surface Comparison

Study of selected specimens of Gymnomitrion collected by D. G. Long in Yunnan, China, revealed a new species, G. fissum Mamontov et Potemkin, sp. nov., with a fissured leaf surface. Comparison of SEM images of the leaf surface and leaf cross sections shows that the leaf surface of G. fissum is different from that of other known species with a superficially similar leaf surface, i. e. Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula. It has fissures around the cell lumen rather than grids and perforations. Outer cell walls of Gymnomitrion fissum are much thicker than in Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula, and their outer layers tend to be partly or completely caducous. G. fissum is related to the group of species assigned to the former genus Apomarsupella.

Calathea hylaeanthoides belongs to Calathea section Breviscapus, C. retroflexa belongs to Calathea section Calathea, and C. incompta belongs to the "Ornata group" of Calathea.

Partial Revision

The genus Robinsonia Grote, 1866 is partially reviewed following a large DNA barcode campaign. In the Robinsonia praphoea Dognin, 1906 group three new species are described: R. simulans sp. n. from French Guiana, up to now confused with R. praphoea itself and then R. decaensi sp. n. and R. maranhensis sp. n. both from the lower Amazon. R. drechseli sp. n. is described from Paraguay and R. inexpectata sp. n., a species close to R. mera (Schaus, 1910) from Costa Rica, is described as new from Peru and Bolivia. Finally the full species status is confirmed for R. flavicorpus Dognin, 1910 which is found to be differentiable from R. marginata Rothschild, 1909. All types are figured along with the male genitalia for most and some female genitalia for all studied species.
