Two new species of amphipods associated with the bioinvasive coral Tubastraea coccinea from Todos-os-Santos Bay are described. The bioinvasive sun coral is known for competing with native coral species, which shelter a big diversity of associated fauna, especially amphipods. Leucothoe oxumae sp. nov. shows acute rostrum, antenna 1 about 1/4 of body length; gnathopod 1 carpochelate, propodus with 5 anterodistal robust setae; gnathopod 2 propodus fusiform, slightly serrated on palmar margin and posterodistal corner of epimeral plate 3 produced and rounded. Stenothoe ogumi sp. nov. is unique by showing a pronounced and developed maxilliped inner plate, gnathopod 2 propodus palm pointed with slightly undulated processes and two developed ones near hinge of dactylus and palmar margin beset with dense fringe of long setae. Updated taxonomic key to Leucothoe and Stenothoe species from Brazil are provided.A new species of the genus Dendrelaphis is described from Xishuangbanna, southern Yunnan, China, based on molecular and morphological data. The new species can be differentiated from other congeners by the following combination of characters 1) ground color of body bronze, a black postocular stripe extending onto the neck only; 2) pale and dark ventrolateral stripe absent; 3) relatively indistinct transverse bands on the anterior part of lateral body; 4) loreal single; 5) vertebral scales strongly enlarged; 6) dorsal scale rows 15-15-11, all smooth; 7) ventrals 193-197, subcaudals 130-135, paired; 8) SVL/TOL ratio 0.292-0.301; 9) supralabials 9, 4th through 6th touching the eye; 10) the outermost row of dorsal scales the same color as other dorsal scales; 11) retracted hemipenis extending to the 6-7th subcaudal scales. According to molecular and morphological data, D. ngansonensis likely belongs to the D. cyanochloris complex. We further discussed D. cyanochloris complex from Tibet, Yunnan and Hainan, China. A key to Chinese species of Dendrelaphis is provided.Catomus aeolicus sp. https://www.selleckchem.com/products/Odanacatib-(MK0822).html nov. is described from the Aeolian archipelago (Sicily, Italy). The new species differs from the other European Catomus by having distinctly bent tibiae, longer antennae (especially in males), and strongly highlighted sexual dimorphism. The shape of the aedeagus also seems diagnostic for this new species.The genus Termitodiellus Nakane, 1961 is a member of the tribe Rhyparini, which includes several morphologically similar genera. Members of Rhyparini can be readily recognized by their carinate dorsal surface, elytral apex with bulbous projection bearing trichomes, hastate posterior prosternal process, and greatly reduced tibial spurs (Howden Storey 1992, 2000; Skelley 2007; Howden 1995; Pittino 2006).The description of the male of the species Quwatanabius chiaw (Smetana, 1995) is provided for the first time, including a habitus photo and illustrations of the aedeagus. A brief discussion of the endemic status of Q. chiaw on the island of Taiwan, as well as additional Taiwanese material of the wide-spread Q. flavicornis (Sharp, 1889) are also provided.The genus Ukamenia Oku (1981) was proposed with Simaethis sapporensis Matsumura (1931) from Japan as its type species, which had been originally described in the family Choreutidae. Oku (1981) based the new genus on characters of S. sapporensis that were typical of Tortricidae rather than Choreutidae, notably the naked haustellum (scaled in Choreutidae), among many other characters differing between the two families, such as wing venation, head morphology, and genital form. Oku (1981) assigned his new genus to the tribe Olethreu-tini, but mentioned that it resembled the genus Gatesclarkeana Diakonoff, 1966. In her extensive study of Australian Olethreutinae, Horak (2006) briefly noted Ukamenia as being referable to Gateclark-eanini.A new geometrid species, Archedontia agnesae sp. n. is described from Tadjikistan. The new genus Archedontia gen. n. is assigned to the sterrhine tribe Rhodometrini, aside genus Ochodontia Lederer. Adult moth, male and female genitalia are figured and described, and COI barcode data analysed.The type material of three Empis s. str. species described by J.E. Collin from Egypt and Syria are revised E. demissa, E. insulata and E. nigropilosa. Lectotypes for Empis insulata Collin, 1937 (Syria) and E. demissa Collin, 1949 (Egypt) are designated. A key to species of Empis s. str. of Egypt, Israel and Syria is provided.Here we consider the morphotypes and changing species composition of naked amoebae in soils of forest areas in Zhytomyr region (Ukraine). The species composition and morphotypes of amoebae are influenced by the microclimate of soil and litter. Complexes of naked amoebae in the study area constitute two clusters one of broadleaf (oak) and mixed forests, another of coniferous forests. The most similar species compositions were found in soils of oak and mixed forests (64 % similarity). The least similar were amoebae complexes of coniferous forests and oak forests, and coniferous forests and mixed forests. Non-parametric multidimensional scaling (MDS) showed that species complex of amoebae of mixed forests and oak forests had moister and more acidic soils compared to coniferous forests.A new species of the hitherto monotypic spider genus Proislandiana Tanasevitch, 1985 is described from the high altitude belt of Ararat Mountain (Turkey) and Aragats Mountain (Armenia). The genus Proislandiana is reviewed, its taxonomic relationships to the other genera are discussed. The diagnoses of the genus and its type species are revised. The distribution and the zoogeography of the two known Proislandiana species are summarized and discussed.This paper brings a series of contributions to the taxonomy of the Zethini description of a new species, Zethus denticlypeus Lopes, sp. n.; description of the female of Z. anomalus Cooper, 1999; description of the males of Z. angustior Bohart Stange, 1965, Z. clypeolaris Bohart Stange, 1965, Z. satanicus Bohart Stange, 1965 and Argentozethus willinki Stange, 1979; synonymy of Discoelius argentinus Brèthes, 1905 under Z. dicomboda Spinola, 1851; and rearrangements for the species of Raphiglossoides Giordani Soika, 1936, with Raphiglossoides minutus (Gusenleitner, 2000) (= R. aethiopicus Giordani Soika, 1936) and R. gibbus (Gusenletiner, 2000) n. comb.
