The monotypic Neotropical genus Ectophasiopsis Townsend, 1915 (Diptera, Tachinidae, Phasiinae) is revised, with the addition of two species (one new and another transferred species), and a redefinition of the genus, accompanied by photographs and drawings of specimens and male terminalia. A new combination is proposed, Ectophasiopsis gradata (Wiedemann, 1830) comb. nov., previously Trichopoda Berthold, 1827, and a new species Ectophasiopsis ypiranga sp. nov. is described. A key for the genera of the “Trichopoda typica” subgroup sensu Sabrosky (1950), as well as a key to species of Ectophasiopsis is given. The geographical range of the genus and the host list are updated.
The genus-group taxon Megatrigon Johnson, 1898, stat. nov., is revised and treated as a valid genus within the Merodontini (= Eumerini). Extensive diagnoses are given for the genus and for its three constituent species groups: argenteus group [11 spp.], nivalis group [monotypic], sexfasciatus group [3 spp.]. Five new generic combinations are proposed within Megatrigon: M. argenteus (Walker, 1852) comb. nov., M. flavimarginatus (Hull, 1964) comb. nov., M. jacobi (Hervé-Bazin, 1913) comb. nov., M. nivalis (Hull, 1964) comb. nov. and M. ochreatus (Hull, 1964) comb. nov. All species of the argenteus group are revised and nine new species are described: Megatrigon apiformis sp. nov., M. argentifrons sp. nov., M. argentimaculatus sp. nov., M. cooksoni sp. nov., M. immaculatus sp. nov., M. magnicornis sp. nov., M. natalensis sp. nov., M. sexmaculatus sp. nov., M. tabanoides sp. nov. Within the sexfasciatus group, M. jacobi (Hervé-Bazin, 1913) comb. nov. is treated as a senior synonym of Eumerus connexus Hull, 1964 syn. nov., but no further work is done at the species level due to insufficient material.
The Neotropical fauna of Gyponini is very diverse and still poorly known. Many new species have characters that do not fit with the currently recognized genera, which makes it necessary to propose new ones. Herein, we propose two new Brazilian genera of Gyponini: Acuthana gen. nov., based on A. transgressa gen. et sp. nov. from the State of Mato Grosso, Central-West Brazil and Rectapona gen. nov. based on R. nigrifascia gen. et sp. nov. from the states of Paraná and São Paulo, South and Southeast Brazil, respectively. Diagnosis, detailed description and illustrations of male and female are provided for each taxon, as well as comparisons with closely related genera.
A new monotypic genus of Iassinae Walker, 1870 tribe Hyalojassini Evans, 1972 is proposed based on Guaricicana borgesi gen. et sp. nov. from the states of Paraná and Rio de Janeiro, southern and southeastern Brazil, respectively. Detailed descriptions and illustrations of males and females are provided, as well as comparisons with the presumably more closely related genus, Daveyoungana Blocker & Webb, 1992.
Recent samplings in cavities of the Iberian Peninsula led to the discovery of a new millipede species of the order Callipodida in one cave in the region of El Bierzo (León, Spain): Lusitanipus xanin sp. nov. In additional samplings (near that cave), more specimens of this new species were discovered in surface habitats. The species has various distinctive characteristics, such as its green colour, but the morphology of the gonopod has several similarities with that of Lusitanipus alternans (Verhoeff, 1893), indicating a close relationship between them. The diagnosis of the genus Lusitanipus Mauriès, 1978 has to be changed to accommodate the new species. The presence of crests in two different sizes is no longer a diagnostic character of the genus Lusitanipus, but of the species L. alternans. Lusitanipus xanin sp. nov. is the fourth species of the order Callipodida for the Iberian Peninsula, and the second species for the genus. Lusitanipus xanin sp. nov. seems to be an epigean but troglophile species.
Scolopendrellidae (Myriapoda, Symphyla) from the Afrotropics with descriptions of seven new species
(2012)
Among the Scolopendrellidae belonging to the collection of Symphyla of the Royal Museum for Central Africa (Tervuren, Belgium), ten species were found and seven new species are described: Symphylella erecta sp. nov., S. fuko sp. nov., S. kalundu sp. nov., S. lubumbashi sp. nov., S. malagassa sp. nov., S. tanganyika sp. nov. and Remysymphyla spinosa sp. nov. SEM micrographs and additional information of the new species and also of Remysymphyla hova Aubry & Masson, 1952, Ribautiella zagnanadina Brölemann, 1926 and R. schoutedeni Hinschberger, 1954 are provided, which contributes to an easier determination of the afrotropical scolopendrellid species. The diagnosis of the genus Remysymphyla is discussed.
A new genus and species of armored scale insect (Hemiptera: Diaspididae), Protomorgania koebelei.
Dooley and Evans, is described and illustrated from specimens collected by Albert Koebele on Pittosporum sp.
(Pittosporaceae) in Australia around the year 1900. A key to the genera of armored scale insects similar to Protomorgania
and known to occur in Australia is provided.
Eight new state records and the three newly described species are the subject of this publication. Whiteflies (Hemiptera: Sternorrhyncha: Aleyrodidae: Aleyrodinae) were collected from 2003 through 2009 within the Las Vegas area of Clark County, Nevada to determine the occurrence of newly established species and host range and distribution. Prior to 2003 the following ten whiteflies were known to be established in Nevada: Aleuroglandulus subtilis Bondar, Aleuroplatus berbericolus Quaintance and Baker, Aleyrodes spiraeoides Quaintance, Bemisia tabaci (Gennadius), Dialeurodes citri (Ashmead), Siphoninus phillyreae (Haliday), Tetraleurodes mori (Quaintance), Trialeurodes abutiloneus (Haldeman), Trialeurodes packardi (Morrill), and Trialeurodes vaporariorum (Westwood). Based on collections made after 2003, eleven additional whitefly species were found in Nevada. Of these the following eight were described species from California and other western U.S. states: Aleuroparadoxus arctostaphyli Russell, Aleuroplatus gelatinosus (Cockerell), Aleuropleurocelus ceanothi (Sampson), Aleuropleurocelus nigrans (Bemis), Tetraleurodes quercicola Nakahara, Trialeurodes corollis (Penny), Trialeurodes eriodictyonis Russell, and Trialeurodes glacialis (Bemis). Three new species are described and illustrated: Aleuropleurocelus nevadensis Dooley sp. nov., Tetraleurodes quercophyllae Dooley sp. nov., and Trialeurodes pseudoblongifoliae Dooley sp. nov.
Five new species of Bakerius Bondar (Hemiptera: Aleyrodidae: Aleurodicinae) are described and illustrated from the Americas and Vietnam based on the adult, nymph, and pupal stages: Bakerius asiaticus, Bakerius colombianus, Bakerius hondurensis, Bakerius leei and Bakerius peruvianus. The following six species: Bakerius attenuatus Bondar 1923, Bakerius calmoni Bondar 1928, Bakerius marmoratus (Hempel 1923), Bakerius phrygilanthi Bondar 1923, Bakerius sanguineus Bondar 1928, and Bakerius sublatus Bondar 1928 are re-described. An identification key to the New World genera of the subfamily Aleurodicinae, and a key to the adults and the puparia of Bakerius species are provided.
Drepanosticta kosterini sp. nov. (holotype ♂, from Gunung Penrissen, Kuching Division, Sarawak, Malaysian Borneo, deposited in RMNH) is described from both sexes. It is the sister species of D. actaeon Laidlaw, 1934; a fresh description of the male of D. actaeon and the first description of the female are given, along with discussion of variation in this species. Both D. actaeon and D. kosterini are considered to belong to a species group also including D. rufostigma (Selys, 1886) and a preliminary discussion of variation in this species is given, along with illustrations of both sexes. A neighbour joining COI gene tree for D. actaeon and D. kosterini is presented. The relationships of D. actaeon, D. kosterini and D. rufostigma to other members of the Platystictidae are briefly discussed.
Results of a collecting trip to the Samunsam Wildlife Sanctuary in western Sarawak are presented. Several species are reported from Sarawak for the first time: Elattoneura coomansi, Mortonagrion cf aborense, Macrogomphus phalantus and Pornothemis starrei. Other notable records include Coeliccia species, Prodasineura cf interrupta and Raphismia bispina.
Records of Odonata collected from Gunung Pueh and the surrounding area, in west Sarawak, in October 2012, are presented. 67 species were collected; two species were recorded in Borneo for the first time: Libellago stigmatizans and Copera ciliata. Othernotable records include Podolestes chrysopus, Telosticta gading, Agriocnemis mini-ma and Pseudagrion coomansi. Some additional, previously unpublished, records from the most western part of Sarawak are included in two appendices.
Odonata recorded during two brief sampling trips to the Kapit Town area in Kapit Division, Sarawak in 2020 are reported on. Seventy nine species were recorded, of which at least six (Onychargia atrocyana Selys, 1865, Ischnura senegalensis (Rambur, 1842), Pseudagrion lalakense Orr & van Tol, 2001, Megalogomphus borneensis (Laidlaw, 1914), Agrionoptera insignis (Rambur, 1842) and Hydrobasileus croceus (Brauer, 1867)) are first records for the division, bringing the total number of Odonata known from the division to 160. Notable records include Coeliccia kenyah Dow, 2010, Teinobasis laidlawi Kimmins, 1936, Burmagomphus insularis Laidlaw, 1914, Leptogomphus sp. cf coomansi Laidlaw, 1936 and Macromia callisto Laidlaw, 1922. Remarks are made on the habitat preferences of Agrionoptera insignis and Camacinia gigantea (Brauer, 1867). A highly atypical population of Neurothemis Brauer, 1867 (species unclear at present) is reported.
Records of Odonata from the southwest of Sri Aman Division and the extreme east of Serian Division in Sarawak are presented. The sampled areas are interesting not only because they are poorly known for Odonata but also because many are just to the south and west of the Lupar Line which is a division between the ancient Sunda shelf and more recent geological formations. Differences between the odonate faunas on either side of the Lupar Line are discussed. Eightyfive species of Odonata were recorded during the surveys reported on. The single most notable record is that of Coeliccia southwelli Dow & Reels, 2011, which represents a considerable extension to the known range of this species. Other interesting records include Telosticta dupophila (Lieftinck, 1933), T. species cf longigaster Dow & Orr, 2012, Podolestes parvus Dow & Ngiam, 2019 and Heliogomphus species cf olivaceous Lieftinck, 1961. Variation in the markings of Stenagrion dubium (Laidlaw, 1912) across its range is discussed and a gene tree using the COI marker is presented to illustrate the high variability of this species in this marker. However the variability in COI does not appear to be correlated with other characters.
The Odonata found during work on the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) Project in Riau Province, Sumatra, Indonesia are reported. Prior to the BEFTA project we are only aware of published records of 37 species of Odonata from Riau Province (these are listed in an appendix). Seventy five species have been recorded during the BEFTA project, including five that have not (Archibasis incisura, Archibasis rebeccae and Pseudagrion williamsoni), or not definitely (Argiocnemis species and Mortonagrion species cf aborense), been recorded in Sumatra before. Macromia dione is recorded for the first time since its description. The number of species now known from Riau Province is 88; 51 of these are reported from the province for the first time here.
A survey of Odonata on the Indonesian island of Belitung is reported. The work of Belitung Biodiversity Observer on Odonata is briefly outlined. Sixty four species were recorded during the survey, including two new records for the island. A checklist of the known odonate fauna, consisting of 105 species, of the island is given in an appendix.
