The flagellar basal apparatus comprises the basal bodies and the attached fibrous structures, which together form the organizing center for the cytoskeleton in many flagellated cells. Basal apparatus were isolated from the naked green flagellate Spermatozopsis similis and shown to be composed of several dozens of different polypeptides including a protein band of 95 kD. Screening of a cDNA libr...

The Nearctic genus Prostoia (Plecoptera: Nemouridae) is reviewed. Prostoia ozarkensis sp. n. is described from the male and female adult stages mainly from the Interior Highland region encompassing portions of Arkansas, Missouri, and Oklahoma. Prostoia ozarkensis sp. n. appears most closely related to two species, one distributed broadly across the western Nearctic region, P. besametsa (Ricker)...

Karyotype, host preference, isozyzme patterns, morphometrics, and mating behavior of two burrowing nematode populations from Hawaii, one infecting Anthurium sp. and the second infecting Musa sp., were compared with Radopholus similis and R. citrophilus populations from Florida. The population from Anthurium sp. had five chromosomes (n = 5), and that from Musa sp. had four (n = 4). Neither of th...

Fourteen adult frogs including six banded frog, Rana camerani and eight marsh frog, Rana ridibunda ridibunda were collected from two sites of Chahar Mahal-o-Bakhtiari province at the southwest of Iran and then were examined for helminth parasites. Only Dolichosaccus rastellus  (50%) was found in R. camerani, Skrjabinoeces similis (50%) and metacercarian cysts of Codonocephalus urniger (12....

Observations on functional morphology and results from experiments demonstrate that setiferous epipods compose the major gill-cleaning mechanism in a penaeoid shrimp, Rimapenaeus similis. Epipods on the second maxillipeds and on pereopods 1-3 are equipped with long setae bearing an array of digitate scale setules. These multidenticulate setae reach to most gills and are jostled among them durin...

Parkella Chickering 1946 = Metacyrba F. O. P.-Cambridge 1901, n. syn.; Parkella venusta Chickering 1946 = Metacyrba venusta (Chickering 1946), n. comb.; Parkella fusca Chickering 1946 and Dendryphantes franganilloi Caporiacco 1955 = Metacyrba venusta (Chickering 1946), n. syn. The six valid described species of Metacyrba are diagnosed and re-illustrated to show previously unrecognized genitalic...

The flat bug genus Longitergus was established by Pham, Bai, Heiss & Cai (2013) with two species: L. productus and L. similis from Vietnam and with L. productus as its type species. Unfortunately, the name Longitergus Pham, Bai, Heiss & Cai (2013) was preoccupied by Longitergus Wang (1993), a subgenus Yezoceryx (Longitergus) Wang, 1993 in Ichneumonidae (Hymenoptera: Ichneumonoidea) based on typ...
