Bongotarsonemus unicornus gen. nov., sp. nov. (Tarsonemidae: Tarsoneminae) is described from adult females and males collected on leaves of Sweet Cherry, Prunus avium L. (Rosaceae). Another species, Bongotarsonemus bicornus sp. nov. is described from adult females collected on leaves of a mountain fern Arthromeris wallichiana (Spreng.) Ching (Polypodiaceae). Both species were collected from the Himalayan forests of Darjeeling district in the State of West Bengal, India. Adult females of this new genus are unusual in having a median raised section of the prodorsum which is delimited by elongated tubercles bearing setae v1 and sometimes sc2. This area is ornamented with sclerotized ridges or elevated strial thickenings; and has a single or bifurcated spear-shaped horn between bases of setae v1. The new genus also has a characteristically bipartite sejugal apodeme and seta d on tibia I often reaching beyond the claw. Adult males are characterized by seta sc2 subequal to sc1; tarsus II with baciliform seta pl'' longer than half the length of the segment, and a conspicuously enlarged solenidion on tarsus IV. Both sexes are unique in having a fish-hook shaped claw on leg I with an elongated shank and strongly curved apex, and seta l' on femur I plumose.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

Abstract The work is focused on the evaluation of variability of morphological and pomological characteristics of several old sweet cherries (Prunus avium L.) that were found in different Slovak regions. The experimental work has been performed during two years, 2014 and 2015. The following characteristics according to the descriptor list of subgenus Cerasus were evaluated - period of flowering and ripening, morphological characteristics of the flowers, fruit size, fruit weight, and quality parameters. The results showed high variability of evaluated accessions. From the 13 surveyed localities, the most valuable accessions were found in the locality Hornį Streda - places Čachtice, Krakovany, Nitra, and Brdárka. During the collecting expeditions, 170 accessions of sweet cherry, with fruit of the different quality were found. The most interesting accessions were grafted onto rootstocks with different intensity of growth (Prunus avium L., Prunus mahaleb L., and ‘Gisela5’). Some of the selected cherry accessions can be used for commercial growing after tests, while some of them can be used only for collection of genetic resources and as potential genitors in breeding programmes.

Little cherry virus disease of sweet cherry (Prunus avium L.) was transmitted under screenhouse conditions by 3 species of leafhoppers (Homoptera: Cicadellidae) out of 24 species tested. Macrosteles fascifrons (Stal), the 6-spotted leafhopper, transmitted the disease in seven tests; Scaphytopius acutus (Say), the sharp-nosed leafhopper, transmitted it once; and Psammotettix lividellus (Zett.) transmitted it once. The transmissions were made from diseased sweet cherry trees of the variety Lambert to indicators of the varieties Star or Sam. With the exception of 1 transmission, 2 to 4 years were necessary following inoculation for unmistakable expression of symptoms in the indicators. M. fascifrons was also implicated in 18 successful transmissions to mature sweet cherry trees grown in the open.
