An ongoing survey for novel phytoplasmas and viruses that affect palms (Arecaceae) and their potential vectors is being conducted in Costa Rica. During that survey, a new species of derbid planthopper (Hemiptera Fulgoroidea) from the palm Astrocaryum alatum H.F. Loomis was found in Heredia State and is here described as Agoo dahliana sp. n. Omolicna dubia Caldwell and O. latens Fennah were also found on coconut palms (Cocos nucifera L.) and represent new country records. Sequence data for the cytochrome c oxidase subunit I (COI) were generated for 9 ingroup (Omolicna Fennah) and 1 outgroup (Neocenchrea Metcalf) taxa; and for 18S ribosomal RNA gene were generated for 8 ingroup plus 2 outgroup taxa (Neocenchrea, Cenchrea Westwood). These data were compiled with available data from GenBank and BOLD for maximum likelihood phylogenetic reconstruction for Omolicna. These results, plus morphological evidence, support changing the status of the genus-group name Agoo Bahder Bartlett from subgenus within Omolicna to full genus, resulting in the new combination of Agoo xavieri Bahder Bartlett. Based on the original description and illustration of the genitalia of Omolicna rubrimarginata Fennah (from Trinidad), we transfer this species to Agoo, creating the combination Agoo rubrimarginata (Fennah), and bringing the total number of species in this genus to three, with A. dahliana sp. n. and A. xavieri currently only known from Costa Rica. Based on both molecular and morphological evidence, O dubia is transferred to Anchimothon Fennah. A key to differentiate the species of Agoo is presented.The new anchovy Stolephorus babarani n. sp. is described on the basis of 26 specimens collected from Panay Island, central Philippines. The new species closely resembles Stolephorus bataviensis Hardenberg 1933 and Stolephorus baweanensis Hardenberg 1933, all these species having a long upper jaw (posterior tip extending beyond posterior margin of preopercle), and numerous dusky spots on the suborbital area (in adults), snout and lower jaw tip. However, the new species differs from S. bataviensis by usually having the posterior tip of the depressed pelvic fin not reaching to vertical through the dorsal-fin origin (vs. extending beyond vertical through dorsal-fin origin), a shorter head (23.9-25.5% of standard length vs. 25.3-28.0%), and a greater distance between the dorsal-fin origin and pectoral-fin insertion (D-P1; 133.9-151.8% of head length vs. 109.9-136.3%). Stolephorus babarani is distinguished from S. baweanensis by having a shorter snout (3.6-3.9% of standard length vs. 3.8-4.6%). Moreover, the new species can be distinguished from S. bataviensis and S. baweanensis by higher gill raker counts on the first and second gill arches (16-18 + 21-23 and 10-13 + 18-21, respectively, vs. 14-17 + 19-22 and 9-12 + 17-20 in S. bataviensis and 14-17 + 19-22 and 9-12 + 17-21 in S. baweanensis). Stolephorus babarani is separated by 5.3% and 10.7% mean p-distances in the mitochondrial COI from S. baweanensis and S. bataviensis, respectively.Farfantepenaeus isabelae is a recently described pink shrimp species with occurrence restricted to the South Atlantic. The real geographic distribution of this species is still uncertain, probably due to difficulties on identification in relation to congeners. The present study aims to increase the knowledge about its occurrence by using an integrative approach with morphology, molecular and niche modeling analysis. Our results extend both western and eastern limits of occurrence of F. isabelae, elucidating gaps along the northern region of Brazil. The knowledge about its distribution will contribute to updating the politics of management and fishing in order to preserve its natural stocks.Perissommatidae is a peculiar relict nematoceran family with one extant genus inhabiting Australia and South America. The family is known since the Middle Jurassic, but the fossil record is very poor and is restricted to Asia. The description of three species of Collessomma gen. nov. from Lower Cretaceous of Transbaikalia and Mongolia-C. sibirica sp. nov., C. gnoma sp. nov., and C. mongolica sp. nov.-expands our understanding of the family in the Mesozoic, when Perissommatidae were much more diverse morphologically and spread geographically then now. Two previously described genera Gurvaniella Kovalev, 1986 and Limnorhyphus Hong, 1983 are transferred to the Perissommatidae.A new genus of family Perlodidae, Parisoperla Huo Du, gen. nov. is described including two new species from Guizhou Province in southwestern China. Both sexes of the new genus are characterized by the posterior margin of tergum 10 with a sclerotized process. The male membranous aedeagus is covered ventrally by patches of fine spines.This synoptic paper is intended to summarize and supplement the information available on the larvae of Thremma McLachlan 1876 in Europe. https://www.selleckchem.com/products/pifithrin-alpha.html We present information on the morphology of the larvae and illustrate the most important diagnostic features. This information is used for the construction of a comprehensive discriminatory matrix for the four European species of family Thremmatidae Martynov 1935 known in the larval stage so far. In the context of this matrix, larvae can be easily diagnosed by the shape of mesonotal sclerites, foretrochantins, forefemora and ventral sclerites on abdominal segment I, by head coloration patterns, by case morphology, and by distribution. In addition, ecological characteristics and distributions of the European taxa are briefly discussed.As preparation for a revision of the Neotropical genera Adelopsis Portevin, 1907, Paulipalpina Gnaspini and Peck, 1996, and Parapaulipalpina Gnaspini, 1996, we review and redescribe the earlier named species and code characters of their genitalia. These characters are then used to redefine species groups. We review the following 22 "older" species Adelopsis ascutellaris (Murray, 1856) (male lectotype here designated); Adelopsis aspera Jeannel, 1936; Adelopsis asperoides Szymczakowski, 1963; Adelopsis azzalii Szymczakowski, 1975 (here raised to specific status-previously as Adelopsis brunnea azzalii); Adelopsis bellator Szymczakowski, 1968; Adelopsis benardi (Portevin, 1923); Adelopsis brasiliensis Jeannel, 1936; Adelopsis brevicollis Szymczakowski, 1975 (here raised to specific status-previously as Adelopsis brunnea brevicollis); Adelopsis bruchi (Pic, 1926) (male lectotype here designated); Adelopsis darwini Jeannel, 1936; Adelopsis grouvellei Jeannel, 1936; Adelopsis heterocera Portevin, 1907 (the type species of Adelopsis, here considered a junior synonym of Adelopsis ruficollis (Portevin, 1903)); Adelopsis insolita Szymczakowski, 1961; Adelopsis luculenta Szymczakowski, 1963; Adelopsis orcina Szymczakowski, 1975 (here raised to specific status-previously as Adelopsis brunnea orcina); Adelopsis ovalis Jeannel, 1936; Adelopsis pteromoria Szymczakowski, 1975 (here raised to specific status-previously as Adelopsis brunnea pteromoria); Adelopsis ruficollis (Portevin, 1903) (male lectotype here designated) (here considered a senior synonym of Adelopsis heterocera Portevin, 1907); Adelopsis triangulifer Szymczakowski, 1961; Parapaulipalpina filicornis (Jeannel, 1936); Paulipalpina dispar (Portevin, 1903) (male lectotype here designated); and Paulipalpina simoni (Portevin, 1903).
