Tabanidae (Diptera) of State of Maranhão, Brazil II. Description of Esenbeckia (Esenbeckia) rafaeli, sp. nov

Esenbeckia (Esenbeckia) rafaeli, sp.nov. is described and figured from nine specimens collected in Carolina, state of Maranh?o, Brazil. The new species is compared with the species Esenbeckia (Esenbeckia) laticlava Wilkerson & Fairchild, 1983; Esenbeckia (Esenbeckia) bitriangulata Lutz & Castro, 1935 e Esenbeckia (Esenbeckia) enderleini Kr?ber, 1931.     

Neotropical Monogenoidea. 32. Cacatuocotyle paranaensis n. g., n. sp. (Dactylogyridae,Ancyrocephalinae) from Characidium spp. (Teleostei,Characidae) from the State of Paraná, Brazil

Cacatuocotyle paranaensis n. sp. (Dactylogyridae, Ancyrocephalinae) is described from the gills of the characid fishes Characidium lanei Travassos and C. pterostictum Gomes collected from two streams on the coast of the State of Paraná, Brazil. Cacatuocotyle n. g. is proposed for species possessing a single cephalic lobe (terminal), one pair of head organs, a convex haptor with thickened muscular anterior margins, one anchor-bar complex (ventral), seven pairs of ventral hooks (one pair associated with the anchor shafts; one central pair anterior to the bar; five submarginal bilateral pairs) and a sinistral vaginal aperture.     

Revision of “Phyllobrotica” from Taiwan with description of Jolibrotica gen. n. (Coleoptera,Chrysomelidae, Galerucinae)

All Taiwanese species formerly classified the genus Phyllobrotica Chevrolat, 1836 are revised. Jolibrotica Lee & Bezděk, gen. n., is described for Phyllobrotica sauteri (Chûjô, 1935) (Taiwan, China: Guangxi) and Phyllobrotica chujoi Kimoto, 1969 (Taiwan). Phyllobrotica shirozui Kimoto, 1969 is transferred to the genus Haplosomoides. All species are redescribed and their diagnostic characters illustrated.     

Ecology,development and pathogenicity of Buddenbrockia plumatellae Schröder, 1910 (Myxozoa,Malacosporea) (syn. Tetracapsula bryozoides) and establishment of Tetracapsuloides n. gen. for Tetracapsula bryosalmonae

Buddenbrockia plumatellae, an enigmatic worm-like myxozoan, was observed as continuously writhing free and attached 'worms' and as free mature spores in the coelom of the freshwater bryozoans Plumatella fungosa, Hyalinella punctata, and Fredericella sp. 'Worm' numbers could double every three days. 'Worms' and spores could be expelled from colonies by external pressure. Some mature 'worms' exited actively, entraining release of free spores, and gradually ceased movement outside the host. Bryozoans sealed off infected regions of the colony. Infected colonies grew slowly, produced no statoblasts, and eventually regressed and died. Transmission was not achieved and prevalence was low. Electron microscopy of 'worms' revealed a single layer of mural cells on a fibrous basal lamina overlying four longitudinal muscle blocks and an inner sheet of two types of proliferating cells, an organization indicative of the bilaterian ancestry of the Myxozoa. Primary type A cells were attached directly by striated tubules to mural cells at positions between muscle blocks. Secondary type A cells had a secretory function. Type B cells underwent meiosis and subsequently developed to typical malacosporean myxozoan spores filling the internal cavity of the 'worms'. External tubes were formed during capsulogenesis in 'worms' from Fredericella sp. Tetracapsula bryozoides is synonymised with Buddenbrockia plumatellae and a new genus is proposed for Tetracapsula bryosalmonae.     

Morphological and molecular reinvestigation of acanthoecid species III. – Kalathoeca cupula (Leadbeater, 1972) gen. et comb. nov. (=Stephanoeca cupula (Leadbeater) Thomsen, 1988)

Based on a further re-examination of loricate choanoflagellate species with detailed morphological (SEM/TEM) and molecular data of the SSU and LSU rRNA, the present study aims to give new insights for Stephanoeca cupula. In contrast to the original allocation within the family of tectiform reproducing species, morphological and molecular data of S. cupula sensu Leadbeater, 1972 points towards an affiliation within the nudiform reproducing family. Based on these new data, we here erect the nudiform genus Kalathoeca with its type species K. cupula gen. et comb. nov. Our data challenges morphological species assignments, as K. cupula shares its morphological lorica characteristics with tectiform reproducing species of Stephanoeca sensu stricto. Kalathoeca cupula is an interesting candidate for further investigating and understanding the evolutionary relationship of tectiform and nudiform reproducing species.Stephanoeca cupula sensu Thomsen, 1988 has been morphologically re-examined based on the renewed understanding of the morphological variability associated with S. cupula sensu Leadbeater, 1972 (=K. cupula), allowing us now to distribute the different morphological forms investigated within K. cupula and Pseudostephanoeca quasicupula.

Description of Micropygomyia (Micropygomyia) ancashensis sp. nov. and the female of Lutzomyia (Helcocyrtomyia) chavinensis Pérez & Ogusuku (Diptera, Psychodidae, Phlebotominae) from Ancash department, Peru

A male of a new species Micropygomyia (Micropygomyia) ancashensis sp. nov. and a female of the Lutzomyia (Helcocyrtomyia) chavinensis Pérez & Ogusuku, 1999 captured in the Antonio Raymondi province, department of Ancash, Peru are described and illustrated. The new species belongs to the cayennensis series, being closest to Mi. lewisi (Feliciangeli Ordo?ez & Férnandez) though presenting highly sclerotized pseudotracheae on the labella that seem to constitute an autapomorphy among American Phlebotominae, and a clypeus almost completely covered with setae, as in Warileya. The female of Lu. chavinensis is close to those of Lu. blancasi Galati & Cáceres 1990, Lu. noguchii (Shannon, 1929), and Lu. pallidithorax Galati & Cáceres 1994.

R. A. Fisher, Lancelot Hogben, and the Origin(s) of Genotype–Environment Interaction

This essay examines the origin(s) of genotype–environment interaction, or G × E. “Origin(s)” and not “the origin” because the thesis is that there were actually two distinct concepts of G × E at this beginning: a biometric concept, or G × E_B, and a developmental concept, or G × E_D. R. A. Fisher, one of the founders of population genetics and the creator of the statistical analysis of variance, introduced the biometric concept as he attempted to resolve one of the main problems in the biometric tradition of biology – partitioning the relative contributions of nature and nurture responsible for variation in a population. Lancelot Hogben, an experimental embryologist and also a statistician, introduced the developmental concept as he attempted to resolve one of the main problems in the developmental tradition of biology – determining the role that developmental relationships between genotype and environment played in the generation of variation. To argue for this thesis, I outline Fisher and Hogben’s separate routes to their respective concepts of G × E; then these separate interpretations of G × E are drawn on to explicate a debate between Fisher and Hogben over the importance of G × E, the first installment of a persistent controversy. Finally, Fisher’s G × E_B and Hogben’s G × E_D are traced beyond their own work into mid-20th century population and developmental genetics, and then into the infamous IQ Controversy of the 1970s.     

Phlebotomine sandflies (Diptera: Psychodidae) from Lábrea,state of Amazonas,Brazil, with a description of Evandromyia (Aldamyia) apurinan Shimabukuro,Figueira & Silva,sp. nov.

An entomological survey was conducted from July-December 2009 and September-December 2010, as part of the epidemiological monitoring of American cutaneous leishmaniasis (ACL) in the municipality of Lábrea, state of Amazonas (AM), Brazil. Sandflies were collected using CDC light traps installed in intra and peridomiciliary locations, as well as the border of forested areas around houses where autochthonous cases of ACL were recorded. A total of 510 sandflies belonging to 26 species were collected. The most abundant species was Nyssomyia antunesi (44.5%) followed by Evandromyia walkeri (10.6%) and Micropygomyia rorotaensis (9.8%). Here we also describe Evandromyia (Aldamyia) apurinan sp. nov. and report new records for Trichophoromyia flochi and Evandromyia sipani in AM and Brazil, respectively. Our results describe the composition of the sandfly fauna in the south of AM and suggest Ny. antunesi as the putative vector in the transmission of Leishmania in this area of the Amazon Region.
