Six species of the genus Bellulia Fibiger 2008 B tenebrosa sp n B clara sp n B jiaxuanae sp n B jiayiae sp n B fuscis sp n and B diannana sp n are described from China and Cambodia Two species Bellulia suffusa Fibiger 2008 and B basalia Fibiger 2010 are reported for the first time from Cambodia GSK2636771 Keys for identifying species in the kareni bella and suffusa speciesgroups and a complete checklist of the genus Bellulia are presentedPhalangopsids are a diverse group of crickets found in all tropical and subtropical regions and includes 1044 valid species Up to now only 22 species were studied cytologically with the chromosome number ranging from 2n 11 to 2n 21 In this paper we studied the chromosomes of 12 phalangopsid species from different Brazilian biomes eight of them reported for the first time and we traced some trends on chromosomal derivation in this group based on chromosome morphology and fundamental number We found that in the phalangopsid species the karyotype concentrates a large amount of metacentric chromosomes the result of successive centric fusions over evolutionary time Moreover pericentric inversions and translocations have been also important in the chromosomal derivation of these cricketsThe Neotropical species of the genus Manota Williston are studied based on material of 146 specimens from French Guiana Ecuador Nicaragua Dominica and the Dominican Republic Four new species are described viz M corniculata sp n French Guiana M pseudocavata sp n French Guiana M truuverki sp n French Guiana and M vladi sp n Dominican Republic Manota defecta Williston 1896 the type species of the genus is listed from Dominica representing the first record since its description more than a century ago from a Southern Caribbean Island St Vincent New records of 13 additional species are provided M acutistylus Jaschhof Hippa 2005 Dominica M aligera Hippa Kurina Sääksjärvi 2017 French Guiana M digitata Hippa Kurina Sääksjärvi

Giavarhynchus Bellò Osella Ruzzier gen n and its type species Giavarhynchus amicorum Bellò Osella Ruzzier sp n are described The new taxon is readily distinguished from all other members of the tribe due to the unique combination of lack of eyes elongate rostrum with a ventral transverse furrow and excised lateral margins located at apical third punctation of pronotum of two distinct sizes arranged in a distinctive pattern interval 7 of elytra protruding from base of pronotum and crenulate basally metafemora bearing a spinelike tooth much larger than that of pro and mesofemora female

nov and B grossepunctatus sp nov are described from Shaanxi central China The two species are morphologically similar to each other in possessing similar cephalic modifications of the male and the aedeagus with a welldeveloped endophallusMegalestes gyalsey Gyeltshen Kalkman Orr 2017 is recorded for the first time from India extending the known geographic range of the species This report is based on the collection of 5 individuals 4 males 1 female from Jang waterfall Tawang Arunachal Pradesh and 2 males from Neora Valley National Park Kalimpong district West Bengal The female of M gyalsey is described for the first time with notes on the variation in the male A probable larva of the species is also described and illustratedThe monophyly and taxonomic validity of some currently accepted genera of gall wasps in the Cynipini Hymenoptera Cynipidae are being challenged by recent systematic studies Here we used morphological and molecular data to redescribe and revise the taxonomic limits of the monotypic genus Kokkocynips PujadeVillar Melika previously recorded only from Mexico We describe a new species from Panama Kokkocynips panamensis Medianero NievesAldrey reared from galls on Quercus salicifolia Neé and add new records from Mexico for the type species of the genus K doctorrosae PujadeVillar Six Nearctic species Dryocosmus rileyi Ashmead 1896 D imbricariae Ashmead 1896 D coxii Basset 1881 D deciduus Beutenmueller 1913 Callirhytis difficilis Ashmead 1887 and C attractans Kinsey 1922 are transferred to Kokkocynips Species of Kokkocynips are associated only with red oaks Quercus section Lobatae Fagaceae and are distributed in the Nearctic and Neotropical regions from Canada through Mexico and Panama Taxonomic limits of Kokkocynips are discussed in light of the molecular phylogenetic relationships of the studied species Diagnostic characters gall description distribution and biological data of Kokkocynips species are given including a key for the identification of the asexual generations of seven speciesThe identities of two East and Southeast Asian species of the plant bug genus Fingulus Distant 1904 Hemiptera Heteroptera Miridae Deraeocorinae Deraeocorini are clarified based on their type specimens The following new subjective synonymies are proposed F longicornis Miyamoto 1965 F brevirostris Ren 1983 syn nov and F ruficeps Hsiao Ren 1983 F henrytomi Nakatani Yasunaga 2018 syn nov Previous records of F umbonatus Stonedahl Cassis 1991 from Hainan China and F collaris Miyamoto 1965 from Zhejiang and Yunnan China are regarded as misidentifications of F ruficeps and F inflatus Stonedahl Cassis 1991 respectivelySea spiders Class Pycnogonida Latreille 1810 are chelicerate arthropods with an extraordinarily reduced body armed with eight to twelve elongated legs A literature review of taxonomic and ecological studies of pycnogonids from Mexico identified 49 nominal species 36 out of 1335 species described worldwide This low species richness is likely caused by limited taxonomic research and intermittent sampling and research efforts initially carried out by foreign scientists 18931996 and later by Mexican scientists The present study investigates the latitudinal gradient of species richness of the pycnogonids associated with nine marine docks located between Cabo San Lucas 2253N and Santa Rosalía 2658N along the west coast of the Gulf of California 2253N Mexico and provides a detailed morphological redescription of each nominal species using light and scanning electron microscopy Nine nominal pycnogonid species and one unidentified species in the genus Tanystylum were collected and identified from the biological samples collected between 20112017 The highest pycnogonid species richness was recorded at Bahía de La Paz seven species 2414N and the lowest species richness at Cabo San Lucas one species without an evident latitudinal species richness gradient Anoplodactylus californicus Hall 1912 and Ammothella spinifera Cole 1904 were the most abundant species 52 of the total number of individuals Tanystylum occidentale Cole 1904 and Nymphon apheles Child 1979 were new geographical records for Mexico and Ammothella symbia Child 1979 and A californicus were new records for Baja California Sur state Adding these new geographical records of pycnogonids increased the species richness previously recorded at Baja California Sur from 20 to 24 nominal species and for Mexico the species richness increased from 49 to 51 nominal speciesPictonorchestia a new genus of talitrid amphipod is established for Orchestia dentata Filhol 1885 from New Zealand It is characterised by the dactylus of gnathopod 2 which has a welldeveloped projection on the posterior margin which interlocks with a shallow sinus on the palm and a proximal spine which defines the palm It differs from other talitrid genera in having gnathopod 1 carpus and propodus with palmate lobes gnathopod 2 dactylus not modified distally pleopods all welldeveloped uropod 1 exopod with marginal setae in one row Pictonorchestia is also unusual in having an incrassate antenna 2 but pereopod 7 not sexually dimorphic a combination shared by only ten other genera none of which have the gnathopod 2 dactylus with a prominent projection on the posterior margin
