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.

A New Species

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.

A New Species

Pelomedusoides is the most diverse clade of side-necked turtles and there is an extensive fossil record (de Broin, 1988; Lapparent de Broin, 2000; Gaffney et al., 2006, 2011) that dates back at least to the Barremian (Lower Cretaceous) (Romano et al., 2014). Its large fossil record evidences a greater diversity in the past, particularly at the end of the Mesozoic, and exhibits a good sampling of species that are represented by skull material (Gaffney et al., 2006, 2011). As a consequence, the most complete and recent phylogenetic hypotheses for this clade (e.g. Romano et al., 2014; Cadena, 2015) are based on matrices comprising a great amount of cranial characters derived largely from Gaffney et al. (2006, 2011). In addition, it is well established that shell characters show a lot of phenotypic plasticity, even in the fossil species (Romano, 2008; Gaffney et al., 2006, 2011). In most cases it consequently is not justified to rely on “diagnostic features” of poorly informative shell-only material for describing a new species. Because of that, most authors remark new morphotypes in the literature when such aberrant specimens are recovered, but do not make any nomenclatural act by proposing a new yet poorly supported species (e.g. Romano et al., 2013; Ferreira & Langer, 2013; Menegazzo et al., 2015). Unfortunately, such a supposedly new bothremydid turtle (Pleurodira: Bothremydidae) from the Early Paleocene of Brazil was recently described based on poorly diagnostic remains (Carvalho et al., 2016; hereafter CGB, for the authors initials) and a correction of this unfounded nomenclatural act is required. In addition I present some comments on shell only material from Brazil in order to guide splitter-taxonomists to stop describing poorly preserved fossil specimens as new species.

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.

AbstractA pycnodont premaxilla bearing a large incisiform tooth with an unusual crown morphology is described from the Palaeocene (Thanetian) phosphate deposits of Morocco. This peculiar tooth shows a broad, fan-shaped multicuspid crown with nine cusps, well adapted for benthic macroalgal scraping. This morph, assigned to a new species of Pycnodus (P. multicuspidatus sp. nov.), emphasizes the phenotypic plasticity of the group and documents an additional trophic specialization among Palaeogene pycnodontiform fishes. In the post-K/Pg boundary marine ecosystem of the Ouled Abdoun Basin, P. multicuspidatus sp. nov. may have opportunistically replaced Maastrichtian fish taxa with a similar front dentition and feeding behaviour, such as the putative specialized pycnodontiforms Stephanodus and Hadrodus.

Lasioseius is a genus widely distributed across the continents, found in many types of hosts. Two new species of blattisociid mites from Brazil, Lasioseius jorgeamadoi sp. nov. and Lasioseius gabrielae sp. nov., are described based on the morphology of adult females collected on buds of cocoa plants, Theobroma cacao L. (Malvaceae) and inflorescences of ornamental plants (Heliconiaceae and Musaceae) in the State of Bahia, and collected on sugar cane, Saccharum officinarum L. in the State of São Paulo. A key for the separation of females of the 14 species of Lasioseius recorded in Brazil is provided.

A New Species

A thermoalkalophilic new species ofBacillus, similar toBacillus arseniciselenatisDSM 15340, produced extracellular xylanase under solid state fermentation when wheat bran is used as carbon source. The extracellular xylanase was isolated by ammonium sulfate (80%) precipitation and purified using ion exchange chromatography. The molecular weight of xylanase was ~29.8 ;kDa. The optimum temperature and pH for the enzyme activity were 50°C and pH 8.0. The enzyme was active on birchwood xylan and little active onp-nitrophenyl xylopyranoside but not on Avicel, CMC, cellobiose, and starch, showing its absolute substrate specificity. For birchwood xylan, the enzyme gave a Km 5.26 ;mg/mL and Vmax 277.7 ;μmol/min/mg, respectively. In addition, the xylanase was also capable of producing high-quality xylo-oligosaccharides, which indicated its application potential not only in pulp biobleaching processes but also in the nutraceutical industry.

A New Species

A new species of Tyrrhenoleuctra from the Balearic Islands, T. antoninoi sp. n., is described on the basis of molecular and biochemical characters. Recent biochemical and molecular analysis clearly demonstrates the distinctness of this species. We describe its relatedness to other species in the genus. We also refer all specimens from the Balearic Islands previously assigned to T. minuta to T. antoninoi. As with all Tyrrhenoleuctra species, T. antoninoi shows marked phenotypic plasticity, presumably due to the variability inherent in temporary streams in which it inhabits.

Theobroma Cacao L

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.
