A new species of aphis, Macrosiphum martorelli is described from the Dominican Republic. This yellow-green aphis attacks the flowers, young buds and tender foliage of "cacao", Theobroma cacao L. causing considerable injuries. Although of no economical importance at present it could be of some importance to the "cacao" industry in the future.

Pterula echo sp.nov. is described from culture. It was isolated from Theobroma cacao L. from Trinidad. Fruitbodies formed on sterile cocoa twigs and on nutrient agar. Optimum temperature for fruiting and sporulation was 20 to 25 °C. Meiosis was normal and chiastic. Phenotypic plasticity of some taxonomic characters in Pterula is discussed.

Cacao was introduced into West Africa in the latter years of the last century and for a time remained relatively free from pests and diseases. It is, in fact, only recently that two major scourges have developed to a point where they are threatening the future of the cacao industry in the Gold Coast and Nigeria. The first, the cacao Mirids (Sahlbergella singularis, Hagl., and Distantiella theobroma, Dist.) is outside the range of the present paper. The second, and most important, is a virus disease, known as “Swollen Shoot”, which is transmitted from tree to tree by at least three species of mealybugs of the family Pseudococcidae.

A review of the literature at large and the field photographic record of the senior author of this study indicate that there are several undescribed species of Aristolochia in Hispaniola (Dominican Republic and Haiti), related to A. bilobata. Here we show that A. mirandae is a synonym of A. bilobata and that what appears as A. bilobata in Marión H. (2011: 76–77) is a new species here described as Aristolochia adiastola. In addition, two new species, A. bonettiana and A. marioniana, also related to A. bilobata, are described and illustrated herein.

A new species of the eusirid amphipod, Rhachotropis reiwa is described from off Amamioshima Island, northwestern Pacific. The new species differs from its congeners in having large eyes, the middorsal tooth on pereonite 7, pleonite 3 and urosomite 1 without middorsal and dorsolateral teeth, the basis of pereopod 5 strongly produced posteriorly, and pereopod 6 with the triangular basis. A key to the species of Rhachotropis from Japanese and adjacent waters is provided. Additionally, a nucleotide sequence of mitochondrial cytochrome c oxidase subunit I from its holotype was determined for the future study.

A new species Neomyrmecridium asymmetricum, found on decaying leaves of Theobroma cacao, is distinguished by grouped conidiophores and polyblastic production of narrow clavate to subclavate, 1-septate, asymmetrical, and yellowish or subhyaline conidia. An ITS- and LSU-based phylogenetic analysis, description, and illustrations are provided. A key and illustrations to Neomyrmecridium species are also presented.
