The unique Neotropical species of the alderfly genus Protosialis van der Weele, 1909, P. bifasciata (Hagen, 1861), is herein transferred to the newly described genus Caribesialis gen. nov. This new taxon is proposed to be sister to the clade Protosialis + Sialis Latreille, 1802, after a phylogenetic analysis that included male genital characters scored on a previous morphological matrix of the family. Also, Ilyobius nigrocephalus sp. nov., a remarkable new species from Ecuador, is described and its phylogenetic position is discussed. Furthermore, Ilyobius bimaculatus (Banks, 1920) from Bolivia, known solely from the female holotype, is redescribed. Based on the present study, the Neotropical fauna of Sialidae is proposed to be constituted by two genera, one insular (Cuba) and one continental (Mexico to Chile and Argentina).
A new genus, Cicatrisphaerion Lingafelter, Morris, Skillman, and Santos-Silva (Coleoptera: Cerambycidae), and three new species of the same authorship, C. wappesi from Quintana Roo, Mexico, C. rileyi from Chiapas, Mexico, and Eupogonius wappesi from Quintana Roo, Mexico, are described. New records and clarification on the distribution of Psyrassaforma janzeni Chemsak, 1991 and P. nitida Chemsak, 1991 are provided. Ameriphoderes amoena (Chemsak and Linsley, 1979) is redescribed based on four male specimens and a new country record from Guatemala is documented. New distributional records are provided for Estola flavobasalis Breuning, 1940 (including a new country record for Bolivia) and Estola vittulata Bates, 1874. A redescription and new distributional record are provided for Eupogonius flavovittatus Breuning, 1940 based on a female specimen.
We recognize and review 40 species of Chlamydastis Meyrick, 1916 (Lepidoptera: Depressariidae) from Costa Rica, including four previously described (i.e., C. vividella (Busck, 1914), revived status; C. phytoptera (Busck, 1914); C. orion Busck, 1920; and C. ungulifera (Meyrick, 1929)) and 36 new species: C. abelulatei Phillips and Brown, new species; C. carolinagodoyae Phillips and Brown, new species; C. angelsolisi Phillips and Brown, new species; C. lindapitkinae Phillips and Brown, new species; C. iangauldi Phillips and Brown, new species; C. anniapicadoae Phillips and Brown, new species; C. antonioazofeifai Phillips and Brown, new species; C. mignondavisae Phillips and Brown, new species; C. marianofigueresi Phillips and Brown, new species; C. colleenhitchcockae Phillips and Brown, new species; C. bernardoespinozai Phillips and Brown, new species; C. bobandersoni Phillips and Brown, new species; C. carlosviquezi Phillips and Brown, new species; C. christerhanssoni Phillips and Brown, new species; C. christhompsoni Phillips and Brown, new species; C. paulhansoni Phillips and Brown, new species; C. elenaulateae Phillips and Brown, new species; C. gladysrojasae Phillips and Brown, new species; C. powelli Phillips and Brown, new species; C. gracewoodae Phillips and Brown, new species; C. juanmatai Phillips and Brown, new species; C. isidrochaconi Phillips and Brown, new species; C. jimlewisi Phillips and Brown, new species; C. jimmilleri Phillips and Brown, new species; C. montywoodi Phillips and Brown, new species; C. johnnoyesi Phillips and Brown, new species; C. luisdiegogomezi Phillips and Brown, new species; C. paulthiaucourti Phillips and Brown, new species; C. dondavisi Phillips and Brown, new species; C. irenecanasae Phillips and Brown, new species; C. manuelzumbadoi Phillips and Brown, new species; C. noramartinae Phillips and Brown, new species; C. vitorbeckeri Phillips and Brown, new species; C. ronaldzunigai Phillips and Brown, new species; C. munifigueresae Phillips and Brown, new species; and C. willsflowersi Phillips and Brown, new species.COI nucleotide sequences (“DNA barcodes”) were obtained for 33 of the species, which helped associate males with females for sexually dimorphic species and revealed a few cryptic, presumably evolutionary siblings. We illustrate adults of all species, along with their male and female genitalia, where available.Nineteen species were reared from caterpillars, and their foodplants are listed. In Costa Rica, 15 species of Chlamydastis are recorded exclusively from Sapotaceae; one species each exclusively from Clethraceae, Vochysiaceae, Combretaceae, and Melastomataceae. Larvae are illustrated for 10 of the 36 new species, and superficial larval descriptions are provided based on photographs and notes. Of the 40 species of Chlamydastis reported from Costa Rica, 32 have been light-collected or reared from Área de Conservación Guanacaste.
The present study provides an important contribution to the knowledge of the geographic distribution of Xestotrachelus Bruner, 1913 (Orthoptera: Romaleidae: Romaleini), a monotypic genus comprised of Xestotrachelus robustus (Bruner, 1911) that has a wide geographic distribution in Brazil. Specimens were collected at the Panga Ecological Reserve, Uberlândia, Minas Gerais, in the Brazilian Cerrado. We provide a key to distinguish Xestotrachelus from other genera found in South America.
Allomyia renoa (Milne, 1935) (Trichoptera: Apataniidae) was described from six females. The male association is verified in this paper. The original type locality information is limited: “Reno, Nev.,‘78, Morrison”. An Allomyia Banks population found at Mount Rose in Washoe County, Nevada, was compared to the A. renoa type material and found to be the conspecific. Figures, descriptions and distribution of male, female, pupal and larval A. renoa are provided.
Two novel species of Russula (Russulaceae, Russulales), R. coronaspora Y.Song sp. nov. and R. minor Y.Song sp. nov. belonging to subgenus Russula crown clade, are described based on both morphological and phylogenetic evidence. In morphology, R. coronaspora sp. nov. is mainly characterized by its distinct spores ornamented with sparse, cylindrical and isolated spines, which resemble coronavirus, and gelatinized pileipellis with pileocystidia mostly septate and sometimes branched; R. minor sp. nov. possesses a very small basidiocarp with pileus less than 2.5 cm in diameter., small basidia, easily peeling and gelatinized pileipellis with slender terminal cells and abundant SV+ pileocystidia. Positions of the two new species in both phylogenetic trees based on ITS and 5-locus sequences (nLSU, mtSSU, rpb1, rpb2 and tef1) confirm their distinct taxonomic status.
Simulium (Trichodagmia) Enderlein, 1934 has an unstable classification system. The broader concept of the subgenus includes five species-groups resulting from an extensive history of synonymisations, often outside of a phylogenetic framework. This concept also ignores relationship hypotheses with the Afrotropical subgenera S. (Anasolen) Enderlein, 1930, S. (Freemanellum) Crosskey, 1969, S. (Xenosimulium) Crosskey, 1969, and the Oviedoi species-group, with several Neotropical species of S. (Trichodagmia). We performed a morphological phylogenetic analysis to test the monophyly of S. (Trichodagmia), its species-groups, and their relationship with the above-mentioned subgenera and Oviedoi species-group. We analysed a data matrix with 69 terminal taxa and 62 characters under parsimony implied weights, with a range of concavities (k1–100), finding three categories of k. Our analysis concludes that S. (Trichodagmia) is not monophyletic, since Oviedoi and the Afrotropical subgenera group with its species-groups Tarsatum and Orbitale. Therefore, we propose a new classification for S. (Trichodagmia) by restricting it to the Orbitale species-group, revalidating S. (Hearlea) Vargas et al., 1946, S. (Hemicnetha) Enderlein, 1934, S. (Obuchovia) Rubtsov, 1947 and S. (Shewellomyia) Peterson, 1975, synonymysing S. (Xenosimulium) with S. (Anasolen), and erecting a new subgenus, S. (Disculter) subgen. nov. for Oviedoi. The geographical distribution of the groups involved is discussed.
The genus Afronurus has several very common mayfly species in China and they are widely distributed in this country. Some of them are quite similar to each other in both imaginal and nymphal stages. However, these species have not been systematically compared and reviewed so far. In this study, six species are recognized. All nymphs of them share the following characters: gills V–VI with additional arrow-like accessory lobes, branched dentisetae, two rows of bristles and setae on hindtibiae and spotted abdominal terga. The males have divergent penes and clearly expressed titillators. The nymphs of the new species A. drepanophyllus sp. nov. have sickle-like gills I, spotted and striped body color, and males have unique genitalia. The nymphal stages of A. furcatus and A. hunanensis, which are associated and described for the first time, have similar body color to A. drepanophyllus sp. nov., but their pale dots on the head capsules and the shape of the hypopharynx are different. Keys to males and nymphs of the six species are provided.
Two new species of the genus Eponisiella Emeljanov, 1984 are described and illustrated from China (Guizhou and Shandong Provinces). These are E. dafangensis sp. nov. and E. shandongensis sp. nov., giving the genus eight species in total. A key to the species of Eponisiella is provided as well as a map of their geographic distribution, which is briefly discussed.
Ophiuroidea is the largest class among extant echinoderms, with over 2000 described species assigned to 33 families. Here, the first identification key to the recently revised classification was developed, and revised morphological descriptions were derived from it, expanding the previous short diagnoses. The key was built by analyzing internal and external skeletal characters of predominantly the type species of each family, including at least two mutually exclusive attributes per family. Various numeric and multistate characters were used to create a traditional as well as an interactive key using the DELTA and Xper software programs. Illustrations (SEM and digital photos) are included in the key to facilitate the assessment of character states by users. Not only is it the first identification key to the families, according to the recently proposed new classification and the examined species, but this interactive key also assists users in understanding the family level taxonomy of brittle stars. The interactive key allows new characters and states to be added, when more species will have been analyzed, without the need to reconfigure the complete key (as may be necessary with conventional keys).
