Tomohide Yasunaga and Ram Keshari Duwal

Abstract

The phyline plant bug genus Randallopsallus Yasunaga, 2013 (Hemiptera: Heteroptera: Miridae: Phylinae) is rediagnosed, with discussion on its tribal placement in the subfamily Phylinae. Current evidence suggests that this unique genus is best placed in Pilophorini and may be closely related to Parastenaridea Miller, 1937. Two new species, Randallopsallus berastagi sp. nov. (from North Sumatra, Indonesia) and R. malayanus sp. nov. (Peninsular Malaysia), are described. A key is provided to facilitate the identification of the three known Randallopsallus species.

Abstract

The plant bug tribe Cylapini (Hemiptera: Heteroptera: Miridae: Cylapinae) is diagnosed and a worldwide key to the genera of the tribe is provided. The taxonomic review of the New World Cylapini genera Amapacylapus Carvalho & Fontes,1968 and Cylapus Say, 1832 is provided, including a key to species, diagnoses and redescriptions of genera and most included species, and descriptions of two new species, Amapacylapus unicolor sp. nov. (Ecuador) and Cylapus luridus sp. nov. (Brazil). Illustrations of the male genitalia, color photographs of the adult and scanning electron micrographs of the selected species are provided. The genus Cylapocerus Carvalho & Fontes, 1968 syn. nov. is proposed as a junior synonym of Cylapus with all species currently placed in Cylapocerus transferred to Cylapus. The following new combinations are established: Cylapus amazonicus (Carvalho, 1989) comb. nov., Cylapus antennatus (Carvalho & Fontes, 1968) comb. nov., and Cylapus tucuruiensis (Carvalho, 1989) comb. nov. Peltidocylapus labeculosus (Bergroth, 1922) is transferred to the genus Amapacylapus as Amapacylapus labeculosus (Bergroth, 1922) comb. nov. Male neotype is designated for Cylapus tenuicornis Say, 1832. The following new country records are provided: Amapacylapus amapariensis Carvalho & Fontes, 1968 (Ecuador, Guyana); Cylapus amazonicus (Bolivia, Ecuador); Cylapus antennatus (Ecuador); Cylapus citus Bergroth, 1922 (Bolivia, Brazil, Guyana, Peru); Cylapus marginicollis (Distant, 1883) (Nicaragua, Panama); Cylapus ruficeps Bergroth, 1922 (Brazil, Colombia, Ecuador); Cylapus tenuicornis (USA); Cylapus tucuruiensis (Venezuela).

Abstract

Type specimens of various taxa of Imatidiini and Hybosispini were examined to verify their identity. The following taxonomic changes are proposed based on these comparisons. New combinations: Cephaloleia apertura (Staines, 2013) comb. nov. (from Aslamidium Borowiec, 1984), Cephaloleia jataiensis (Pic, 1923) comb. nov. (from Xenispa Baly, 1859), Pseudimatidium bicoloricornis (Pic, 1926) comb. nov. (from Windsorispa Sekerka, 2014), Xanthispa miniacea (Blanchard, 1843) comb. nov. (from Homalispa Baly, 1859), Xenispa aeneipennis (Baly, 1859) comb. nov. (from Cephaloleia Chevrolat, 1836), Xenispa gilvipes (Uhmann, 1930) comb. nov. (from Cephaloleia), Hybosispa claripes (Pic, 1923) comb. nov. (from Solenispa Weise, 1905), Hybosispa delectabilis (Staines, 1996) comb. nov. (from Cephaloleia), Hybosispa sulciceps (Baly, 1885) comb. nov. (from Cephaloleia), and Hybosispa truncatipennis (Baly, 1869) comb. nov. (from Cephaloleia). New synonyms: Cephaloleia impressa Uhmann, 1930 = Demothispa clermonti Pic, 1934 syn. nov.; Xenispa atra (Pic, 1926) = Cephaloleia cyanea Staines, 1996, syn. nov. Change in status: Cephaloleia fernandoi (Bondar, 1940) stat. restit. is removed from synonymy with C. opaca Baly, 1859. The monotypic genus Serratispa Staines, 2002 assign. nov. is transferred from Sceloenoplini to Imatidiini based on morphological characters. Three species are described: Cephaloleia fouquei sp. nov. from Bolivia and Peru, C. renei sp. nov. from Ecuador, and Xenispa fouquei sp. nov. from Venezuela. Keys to Cephaloleia basalis Weise, 1910 species-group, Venezuelan species of Xenispa Baly, 1859, and species of Hybosispa Weise, 1905 are proposed to simplify identifi cation of respective taxa. Most of the taxa discussed herein are provided with colour photographs.

Abstract

Selected type and non-type material belonging to the genus Orthocladius van der Wulp, 1874 (Diptera: Chironomidae) sensu GOETGHEBUER (1940-1950), deposited in the Royal Belgian Institute of Natural Sciences (RBINS), originally comprising specimens dry pinned or stored in isinglass, were mounted on microscope slides and re-examined. Other chironomids present in the RBINS collection belonging to other genera were also examined. Fifty slides were prepared and identified to species, or to generic level when the condition of the specimens did not allow species identification. The following types, representing taxa formerly considered as nomina dubia, were examined and the concerned species are stated here as valid: Georthocladius collarti (Goetghebuer, 1941) comb. nov., Georthocladius scaturiginis (Goetghebuer, 1940) comb. nov., Lapposmittia succinea (Goetghebuer, 1942) comb. nov., Orthocladius (Euorthocladius) tolleti Goetghebuer, 1944 (new subgenus placement), Orthocladius (Orthocladius) timoni Goetghebuer & Timon-David, 1939, Pseudorthocladius hockaiensis (Goetghebuer, 1933). Orthocladius (Orthocladius) mitisi Goetghebuer, 1938, previously stated as junior synonym of Orthocladius (Orthocladius) glabripennis (Goetghebuer, 1921), is reinstated as valid species. The following new synonyms are proposed: Georthocladius (Georthocladius) collarti = Parachaetocladius retezati Albu, 1972: 19, syn. nov.; Cricotopus (Paratrichocladius) rufiventris (Meigen, 1830) = Orthocladius franzi Goetghebuer, 1949, syn. nov.; Cricotopus (Paratrichocladius) skirwithensis Edwards, 1929 = Orthocladius nigritus Goetghebuer, 1938, syn. nov. = Paratrichocladius spiesi Ashe & O’Connor, 2012; Hydrobaenus distylus (Potthast, 1914) = Orthocladius antennalis Goetghebuer, 1944, syn. nov. Lectotypes of Orthocladius collarti Goetghebuer, 1941, Orthocladius antennalis Goetghebuer, 1944, Orthocladius timoni Goetghebuer & Timon-David, 1939, and Orthocladius hockaiensis Goetghebuer, 1933 are designated. Non-type material assigned to Orthocladius was also mounted on slides and identified. Although a list of the non-Orthocladius taxa is also provided, no taxonomic changes are proposed for the latter.

Abstract

Species of the genus Epuraea Erichson, 1845 from New Zealand are revised and redescribed. The New Zealand fauna comprises six species. One new species, Epuraea glabrata sp. nov. is described. Epuraea mayendorfii (Reitter, 1873) is provided as a valid replacement name for Nitidula lateralis (White, 1846), not Nitidula lateralis C. R. Sahlberg, 1820. One new synonymy is proposed, Epuraea mayendorfii (Reitter, 1873) = Epuraea zealandica Sharp, 1878, syn. nov.

Abstract

The Venezuelan species of the genus Gyrinus Geoffroy, 1762 are reviewed (Gyrinidae: Gyrininae: Gyrinini). The Venezuelan Gyrinus fauna is found to be comprised of nine species distributed among the subgenera Neogyrinus Hatch, 1926 and Oreogyrinus Ochs, 1935, although Gyrinus (Oreogyrinus) colombicus Régimbart, 1883 is known from imprecisely localized and potentially mislabeled specimens and the species presumably does not occur in Venezuela. Three new species are described: G. (Oreogyrinus) vinolentus sp. nov. from the Andes, and G. (Oreogyrinus) iridinus sp. nov. and G. (Neogyrinus) sabanensis sp. nov., from the Guiana Shield region. Two new synonymies are established: G. amazonicus Ochs, 1958 syn. nov. is synonymized with G. guianus Ochs, 1935, and G. racenisi Ochs, 1953 syn. nov. is synonymized with G. ovatus Aubé, 1838. Gyrinus (Oreogyrinus) feminalis Mouchamps, 1957, described from Venezuela from two female syntypes only, is considered as species inquirendum, as the types were not found. For each species a dorsal habitus, illustration of male and female genitalia, and distribution map are provided. A key and checklist for the Venezuelan Gyrinus species is included.

Abstract

Renefouqueosis peruviensis gen. et sp. nov., a new tenebrionid genus and species of the tribe Stenosini (subtribe Stenosina) is described from the arid mountains of Northern Peru. Including the new genus Renefouqueosis gen. nov., the tribe Stenosini now includes 40 valid genera of which nine are from the New World. The genera are placed in six subtribes (two worldwide, two New World and two Old World). Type species and subtribal assignment for each genus is presented. Notes on the placement of the genera Anchomma LeConte, 1858 and Fitzsimonsium Koch, 1962 are given. The proper placement of these genera is uncertain. Because of numerous morphological similarities to the Stenosini, we have decided to place these in a key to the world genera of Stenosini, which we provide.
