Phylogenetic relationships and species diversity within the genus Halymenia along the Brazilian coast were investigated through molecular and morphological analyses. Molecular studies included UPA, COI-5P and rbcL markers. A total of five Halymenia species were found: Halymenia cearensis sp. nov., H. ignifera, H. pinnatifida, H. silviae and H. cf. mirabilis. Halymenia cearensis was molecularly distinct from all other Halymenia species included in this study and is morphologically characterized by: cleft, lobate, oblong or obovate blades with broad base; apex irregular in shape; surface with bullations, rugosities, spiny and globular papillae irregularly distributed; abundant and conspicuous ganglionic cells throughout; blades up to 800 µm thick at base; outer cortical cells ellipsoidal or ovoid in shape, higher than broad; and inner cortex cells 4–25 µm in width. Our phylogeny demonstrated that entities attributed to H. floridana and H. elongata occurring in Brazil correspond to two distinct genera, which was also supported by morphological and ecological data. The use of molecular tools was crucial to provide a better understanding of the diversity of Brazilian marine flora.

Abstract A description is provided for Micronectriella nivalis[Monographella nivalis]. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: The fungus is a serious pathogen of cereals (barley, wheat, rye) and grasses, especially in temperate regions where it may cause total loss of winter sown wheat and rye (43, 1873; 48, 3456). Tropical records, especially those on rice, need to be confirmed. DISEASE: Pre-emergence blight, root rot and occasionally head blight of cereals. Snow mould of turf. GEOGRAPHICAL DISTRIBUTION: Europe, extremely widespread, USSR, Japan, Australia, New Zealand, N.E. and N.W. USA and Canada. Records have also been cited of its occurrence in India and West Africa (CMI Map 432, ed. 1, 1967). TRANSMISSION: By seed, soil, water and in summer by aerial dissemination of ascospores (48, 1628).

Abstract Within Hymenoptera, the superfamily Chalcidoidea (chalcidoid wasps) is the second largest superfamily after Ichneumonoidea. Because of the preponderance of parasitoid species, Chalcidoidea is one of the most important groups in applied biological control. This book provides a comprehensive, accurate checklists for the chalcidoid fauna of Iran. The species listed in each family chapter include all the species recorded in the literature from Iran through 2019, with one exception as noted in Chapter 10 (Eurytomidae). Each family chapter includes differential characters to distinguish the family, hypothesized phylogenetic relationships with other families, and general biological attributes of the family. Previous cataloguing efforts of the Iranian fauna for the family are summarized, as well as the information included in the checklist of species for the family. This summary information includes the number of species recorded from Iran, any newly recorded species, a comparison of the Iranian fauna with those of adjacent countries, and major host attributes of the family in Iran. Also included for each species record are host records and plant associates in Iran, when known, and additional comments as necessary. The final chapter tabulates the species diversity of Iranian Chalcidoidea by family, the species newly exclude from Iran, the species presently considered as endemic to Iran and the number of species of each family that are known from each of the 31 provinces that comprise Iran. Because of the importance of chalcidoids for biological control of pests in Iran, host information for parasitoid species that is provided throughout the chapters is synthesized in an Appendix at the end of the book.

Three new species in the diatom genus Eunotia were found in the freshwater ponds and streams of Acadia National Park, Maine, USA. Eunotia novaeangliae sp. nov. belongs to the E. incisa group, species with nose-like apices and terminal raphe fissures distant from the ends. It is most similar to E. tenelloides in that species cluster, although differs in the valve shape, geographical distribution, several ultrastructural details and slight but consistent differences in valve dimensions and striae density. Eunotia panda sp. nov. is in the E. bilunaris group, species with slight even curvature and smooth margins of the valves. However, E. panda can be distinguished from E. bilunaris by dorsally slightly recurved apices with rounded ends, ultrastructural details and noticeably constant valve width. Eunotia spatulata sp. nov. is most similar to E. eurycephala, but differs from that taxon by having straighter and significantly larger valves with more swollen apices. All three taxa were sufficiently abundant in the samples collected from the park that they could be found in both SEM and LM microscopes. Eunotia novaeangliae and E. panda have both been illustrated in other publications before but not named. All three species occurred in waters of low conductivity and pH, typical for the genus. Acadia National Park appears to be a hotspot for Eunotia species diversity, and further study of the oligotrophic waters of this site is certainly warranted.

AbstractEight genera and 25 species are recognized among the Nearctic, Mexican, and West Indian Oodini. Four new species are described: Oodinus pseudopiceus (type locality: Hillsborough River St. Pk., Hillsborough Co., Florida); Oodinus similis (type locality: San Quintín, Chiapas, Mexico); Oodinus darlingtoni (type locality: Cauto El Cristo, Oriente, Cuba); and Oodinus edentulus (type locality: 31.8 mi E Francisco Escárcega, Campeche, Mexico). Oodes fluvialis LeConte, 1863, previously recognized as a subspecies of O. americanus Dejean, 1826, is given specific status. The following new synonymies are established: Eulachnocrepis Habu, 1956 with Lachnocrepis LeConte, 1853; Stenocrepis texana (LeConte, 1863), S. chalcas Bates, 1882, and S. chalcochrous Chaudoir, 1883 with S. insulana (Jacquelin du Val, 1857); Stenocrepis quatuordecimstriata (Chaudoir, 1843), S. picipes (LeConte, 1844), S. stenocephala (LaFerté-Sénectère, 1851), and S. sulcata Chevrolat, 1863 with S. mexicana (Chevrolat, 1835). Lectotypes are designated for Oodinus alutaceus (Bates, 1882), Oodes amaroides Dejean, 1831, O. fluvialis LeConte, 1863, O. americanus Dejean, 1826, Stenocrepis texana (LeConte, 1863), S. chalcas Bates, 1882, S. lecontei (Chaudoir, 1857), S. quatuordecimstriata (Chaudoir, 1843), S. picipes (LeConte, 1844), S. cuprea (Chaudoir, 1843), S. tibialis (Chevrolat, 1834), S. femoralis (Chaudoir, 1835), S. elegans (LeConte, 1851), and S. gratiosa (Bates, 1882). The genus-group name Nanodes Habu, 1956, a homonym of Nanodes Schönherr, 1825, is replaced by Nanodiodes, new replacement name. For each genus treated, the following are provided: citation of original description and selected references, notes about synonymy (if required), description, geographical distribution and diversity, and monophyly and phylogenetic relationships. For each species included, the following are given: citation of original description and synonymies, type material, etymology (for new species only), notes about synonymy (if required), diagnosis, description, geographical distribution, bionomics, and phylogenetic relationships (if the genus includes more than two species). Keys to genera and, for each genus, to species are included. The species distributions are mapped, and the important structural features are illustrated.
