A new species of the genus Palaeagapetus Ulmer (Trichoptera, Hydroptilidae) from Japan

A new species of hydroptilid caddisfly, Palaeagapetus fukuiensis sp. nov., is described based on adult and immature stages from Japan. The habitat and food of this species are noted. This species is more closely similar to the Russian Far Eastern species of Palaeagapetus than to the Japanese species.     

Compound eyes and ocular pigments of crustacean larvae (Stomatopoda and decapoda,brachyura)

Larvae of decapod and stomatopod crustaceans possess paired compound eyes not unlike those of adult crustaceans. However, the visual demands of larval and adult life differ considerably. Furthermore, the eyes of adult stomatopods appear to be far more specialized than those of the larvae. We examined eyes of several stomatopod species just before and after larval metamorphosis. At this time, the entire larval retina is joined by a new, adult‐type retinal array which gradually replaces the remnants of the larval retina. The new retina of the postlarva is anatomically similar to that of the full‐grown adult, and has virtually identical assemblages of intrarhabdomal filters. We determined the photopigments of Gonodactylus aloha, the only species for which we were able to obtain both larval and adult specimens, using microspectrophotometry. The single middle‐wavelength larval rhodopsin (λ_max= 499 nm) disappears at metamorphosis; none of the 10 classes of adult rhodopsins has λ_max between 473 and 510 nm. This metamorphic change of visual pigment does not occur in a comparison species of decapod crustacean, the blue crab Callinectes sapidus. Here, rhodopsins both of the megalops larva and the adult had λ_max at 503–504 nm. The difference between these two species can be explained by the varying ecological requirements of their larvae and adults, and more study of visual pigments in retinas of larval and adult crustaceans is warranted.     

Soft scale insects (Homoptera: Coccidae) on Tillandsia in Central America*

A new genus of soft scale insect (Homoptera: Coccoidea: Coccidae), Tillancoccus, and two new species T. mexicanus and T. tillandsiae are described and illustrated from the adult females. The new species are recorded from Tillandsia plants in Guatemala, Honduras and Mexico.     

A New Species of the Neotropical Genus Oukuriella Epler (Diptera,Chironomidae, Chironominae)

The male of a new species of Oukuriella Epler, 1986, O. gracilis sp. n., is described from Brazil. The new species is distinguished by slender abdominal segments, distinctive setal tufts on abdominal tergites, markings on the abdominal segments, and brownish rings distally on the tibiae. A key to adult males of Oukuriella is provided.

Description of Optioservus gapyeongensis new species and Heterlimnius hasegawai (Nomura) (Coleoptera: Elmidae) new to Korea

A new riffle beetle species Optioservus gapyeongensis n. sp. is described from the adult and larval stages. Heterlimnius hasegawai (Nomura), previously misidentified in Korea as Optioservus (Cyclolimnius) kubotai Nomura or Optioservus variabilis Nomura, is redescribed. The adults and larvae of both species inhabit attached mosses on substrates of clean mountain streams, headwaters or springs. Photographs of dorsal adults and habitats and line drawings of diagnostic characters are provided.     

New species of parasitic copepods of the Genus Acusicola (Poecilostomatoida: Ergasilidae) from gill filaments of coastal and freshwater Brazilian fishes, and proposition of Acusicola rogeri n. sp. for A. tenax sensu Cressey & Collette (1970)

Four new species of Acusicola are described based on adult females found on gill filaments of several species of coastal and freshwater fishes caught in Brazilian basins. The distribution area of the genus in Brazil is significantly enlarged, since until now the previous Brazilian species had been known only from Amazonian fishes. The specimens identified as Acusicula tenax by Cressey and Collette (1970) are considered representatives of a new species, A. rogeri. A key for identification of the species of Acusicola is provided.

Descriptions of two new and one little known species of the genus Cacopsylla (Hemiptera: Psyllidae) on Sorbus japonica (Rosaceae) and an observation of their biology

Three species of the genus Cacopsylla were collected from Sorbus japonica in Japan. Two of them, Cacopsylla elegans and Cacopsylla sorbicoccinea, are described as new species based on adults and fifth (final) nymphal instars. The third species, Cacopsylla midoriae, is newly transferred from the genus Psylla. The adult of C. midoriae is redescribed and the nymph is described for the first time. A key to the species feeding on S. japonica (adults and nymphs) is provided. The three species were observed to coexist on the same tree of S. japonica in northern Kyushu. Such coexistence of psylloid congeners is uncommon in Japan.     

The mosquitoes (Diptera: Culicidae) of Tabasco,Mexico

To document and update the mosquito species of Tabasco, Mexico, field collection trips were conducted in the two physiographic regions of Tabasco: the coastal plain of the southern gulf and the mountains of Chiapas and Guatemala. Mosquitoes were collected as immature and adult stages during the dry and rainy seasons from 2014 through 2015. Additionally, the Reference Collection of Arthropods of Medical Importance (CAIM‐InDRE) containing mosquitoes of Tabasco was re‐examined. In total, 4,913 specimens were collected and examined, which are divided into seven tribes, 18 genera, 27 subgenera, and 104 species. Of these, one genus (Shannoniana Lane and Cerqueira), two subgenera (Georgecraigius Reinert, Harbach and Kitching, and Carrollia Lutz), and 21 species are new records for the mosquito fauna of Tabasco. Culex metempsytus Dyar is a new record for Mexico and Wyeomyia jocosa (Dyar and Knab) is removed from the Mexican mosquito fauna. Seventeen species historically reported were not found in the field collections conducted here. Taxonomic notes, new distribution limits, and comments about the medical importance of species of mosquitoes of Tabasco are discussed. Tabasco is the second state in Mexico with the largest mosquito richness (104 species), followed by Veracruz with 139 species.

Three new species, Glyptotendipes (Glyptotendipes) fumilatus, G. (G.) ingenius and G. (G.) validens are described. A short account of habitat, construction of dwellings, food and feeding of the larva and emergence of the adult has also been appended. A new dichotomous key to the Indian species is provided.     

Revision of the genus Ornithocheyletia Volgin, 1964 (Acari: Cheyletidae)

Summary The genus Ornithocheyletia Volgin, 1964 is revised. If the three species described below are included the number of known species in this genus is now 22. These species live on or in the skin of birds and produce mange. The holotypes of all these species have been examined except those of O. pinguis (Berlese) and of O. dubinini Volgin which were not available. Three new species and one new subspecies are described: O. geopeliae sp. nov. from Geopelia striata, O. lepidus sp. nov. from Garrulax leucolophus bicolor, O. eulabes from Eulabes javana and O. psittaci poicephali ssp. nov. from Poicephalus senegalus. O. similis Fain, 1972 is placed as a subspecies of O. hallae Smiley, 1970. The genus Ornithocheyletia is redefined and a key to the species is provided. The following stages have been observed in the life cycle: egg—prelarva—larva— protonymph—tritonymph—adults. A prelarva is observed for the first time: it is represented by a small ecdysis organ consisting of two small bifid sclerites serving for the rupture of the eggshell. The adult female develops into a tritonymph, the adult male into a protonymph. The males are either homeomorphic or heteromorphic; the latter are characterized by the hypertrophy and modification of the gnathosoma, especially the palps. ac]19800531

E. medogana sp. nov., E. nigra sp. nov., E. purpurata sp. nov. and E. simipunicea sp. nov.） are new to science and three （E. admirabilis Kirpichnikova, E. fuscobasalis Ragonot and E. valentis Kirpichnikova） are recorded for the first time in China. The adult features and genital structures of the new species are illustrated and a key to the Chinese species is given.     

A new species of Rhynchoidomonas Patton, 1910 (Kinetoplastida: Trypanosomatina) from Operophtera brumata (Lepidoptera: Geometridae)

Summary A new species of Rhynchoidomonas Patton was observed in a single adult male winter moth, Operophtera brumata (L.) from England. Intracellular amastigotes, and extracellular epimastigotes and trypomastigotes with an undulating membrane and free flagellum, were present. All stages had a large, reniform kinetoplast. As transmission of the flagellate between generations of winter moths by ingestion of infected faeces is a virtual impossibility, it is suggested that the flagellate's true host may have been a dipteran parasitoid and that an egg, surface-contaminated with the flagellate, was oviposited into or ingested by a winter moth larva. If the parasitoid had died, this flagellate infection could have been carried over to the adult moth. ac]19830601     

Responses to urinary stimuli in pigtailed (Macaca nemestrina) and stumptailed (Macaca arctoides) macaques

Responses to different urine samples were studied in pigtailed (M. nemestrina) and stumptailed (M. arctoides) macaques. Both species exhibited more interest towards urine samples from their own species than neutral stimuli. Responses towards urine samples from other macaque species did not significantly differ from those towards neutral stimuli. In stumptailed macaques, no differential interest was observed between urine samples from a known (the adult male of the group) and an unknown adult male conspecific.     

World revision of Ortheziola Šulc (Homoptera: Coccoidea: Ortheziidae) with descriptions of eleven new species

Soil samples and museum collections were analysed from all zoogeographic regions of the world. From this material eleven new species of Ortheziola?ulc are described from Africa and the U.K., five additional species are redescribed and a key is presented for the identification of all sixteen species. A slightly modified concept of the genus is presented and several new characters are given as diagnostic of the genus. A phylogenetic hypothesis is given based on analysis of the morphological features of adult females. Results show that Ortheziola is most diverse in eastern Africa where relatively more advanced species occur. Basal species occur primarily in western Africa and Asia.
