Additionally, a detailed description of the female of Eupogonius fulvovestitus Schaeffer, 1905 is provided for the first time, along with notes on the likely host of the species. New state records in Mexico are provided for Eupogonius comus Bates, 1885, and E. stellatus Chemsak and Noguera, 1995. Other taxonomic or nomenclatural actions included herein are: Eupogonius knabi Fisher, 1925 is transferred to Atelodesmis Chevrolat, 1841, new combination; the gender of the species-group name in Eupogonius azteca Martins, Santos-Silva and Galileo, 2015 is commented on; notes on the geographical distribution of Eupogonius affinis Breuning, 1942, and the problematic morphology of E. infimus (Thomson, 1868) are presented; Eupogonius subaeneus Bates, 1872, and E. marmoratus Fisher, 1925 are revalidated, and E. columbianus Breuning, 1942 is a new synonym of E. subaeneus”.
In the course of working on new species of North American Phyllophaga Harris, 1827 (Coleoptera: Scarabaeidae: Melolonthinae) some synonyms have been found and are proposed here. New synonymies: Phyllophaga knausii (Schaeffer, 1907) is synonymized with Phyllophaga sociata (Horn, 1878); Phyllophaga chippewa Saylor, 1939 is synonymized with Phyllophaga rugosa (Melsheimer, 1845); and Phyllophaga falta Sanderson, 1950 is synonymized with Phyllophaga bipartita (Horn, 1887). Lectotypes are here designated for the following species: Listrochelus knausii Schaeffer, Listrochelus sociatus Horn, and Lachnosterna bipartita Horn. A neotype for Ancylonycha rugosa Melsheimer is here designated from the Horn Collection.
Revision of the species confused with "Nereis falsa" de Quatrefages, 1866 (Annelida, Nereididae)
(2021)
Nereis falsa de Quatrefages, 1866 has been regarded as a cosmopolitan species, and several species described from different localities have been regarded as junior synonyms of N. falsa. The present study is an attempt to resolve the taxonomic confusion in N. falsa, which seems to contain several distinct species due to previous inappropriate synonymy, widely distributed in the Atlantic and eastern Pacific Oceans. For this purpose, the authors first propose the resurrection of the synonymy of N. falsa with Hediste diversicolor that was concluded during the 19th century but disregarded later. After the fixation of the identity of N. falsa sensu stricto, the authors re-evaluate the proper taxonomic status of species which have previously been confused with N. falsa. Type, topotype and non-type specimens were examined; most species are redescribed, and others are reinstated. Nereis splendida Grube, 1840 is a valid Mediterranean species, and a neotype is proposed; it includes the Mediterranean populations of what is currently regarded as N. falsa. Consequently, N. falsa is transferred to Hediste Malmgren, 1867, and some taxonomic comments are added for the latter genus and a key to species is also included. Nereis callaona Grube & Kröyer in Grube, 1857, N. marginata Grube & Örsted in Grube, 1857 and N. riisei Grube & Örsted in Grube, 1857 are restricted to tropical American shores and are all redescribed. Nereis pelagica lunulata Ehlers, 1901, formerly regarded as a junior synonym of N. falsa by Fauvel (1941), is redescribed and elevated in rank to species level. Nereis lucipeta Ehlers, 1908, formerly regarded as a junior synonym of N. splendida by Ehlers (1913) and of N. falsa by Fauvel (1919), is reinstated. Nereis occidentalis Hartman, 1945 is also redescribed. Furthermore, N. ambigua Treadwell, 1937, formerly regarded as a junior synonym of N. riisei by Monro (1933), deserves to be reinstated. Western Africa specimens recorded as N. falsa are newly described as N. mezianei sp. nov.
Three species of Corethrella Coquillett, 1902 from the state of Amazonas, Brazil are described as new to science based on female adult specimens. Corethrella cabocla Feijó, Belchior, Marialva & Pessoa sp. nov. possesses four large setae on the frons between the ventromedial area of ommatidia, a wide clypeus with 1–4 setae, a wing with the apex of R2 basal to the apex of M2 and with a midlength band, and with the abdomen entirely dark brown. Corethrella ielemdei Feijó, Ramires, Lima & Pessoa sp. nov. possesses an elongated coronal suture, four large setae on the frons between the ventromedial area of ommatidia, a clypeus squarish with 42–43 setae, a wing with the apex of R2 basal to the apex of M1 and with a midlength band and dark scales on the basal and subbasal areas of the anterior margin, legs with dark scales, and with the abdomen entirely dark brown. Corethrella menini Feijó, Picelli, Ríos-Velásquez & Pessoa sp. nov. possesses wings with the apex of R2 basal to the apex of M2 and a midlength band, with darker basal scales along all veins, basal band dark scales on C, Sc, R, M, and Cu and the abdomen entirely dark brown. With the addition of the new species, the numbers of frog-biting midges described in the Amazon basin, Brazil and in Neotropical region are now 31, 49 and 80 species, respectively.
Two new genera of Acanthocinini (Coleoptera: Cerambycidae), Luctithonus Lingafelter and Duocristala Lingafelter, are described from Hispaniola. Two new species of Luctithonus are described: Luctithonus aski Lingafelter and L. duartensis Lingafelter. A third species, L. pantherinus (Zayas), is newly recorded from Hispaniola and the Dominican Republic (new country record), and transferred from Sternidius Haldeman as a new combination. Additional new species of Lamiinae are described from Hispaniola: Eugamandus albipumilus Lingafelter; Leptostylopsis opuntiae Lingafelter; and Lethes turnbowi Lingafelter. Keys to tribes of Lamiinae, genera of Acanthocinini, and species of Luctithonus in Hispaniola are included.
Crioprosopus baldwini Eya (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini), sp. nov., from Costa Rica and Panama, is described. An amendment to the key to species of Crioprosopus Audinet-Serville, 1834, as presented in Eya (2015), is provided along with illustrations of the key characteristics to differentiate C. baldwini from other species.
The tribal allocation of Xalitla Lane, 1959 (Cerambycidae: Cerambycinae) is discussed. Xalitla limoni Santos-Silva and Skillman, new species,is described from Mexico (Jalisco). Xalitla lezamai Galileo and Martins,2008 is determined to be synonymous with X. genuina Martins,1970 and formally placed in synonymy. A key to the species of Xalitla, which includes the new species and synonymy, is provided.
The number of specimens in the type series of Hemilophus leuconotus Laporte, 1840 (= Cirrhicera leuconota) is corrected. Cirrhicera leucronota Thomson, 1857 (Coleoptera: Cerambycidae: Lamiinae: Hemilophini), currently considered lapsus calami or an error to C. leuconotus, and the number of specimens in the type series is also corrected. Cirrhicera leuconota is recorded from Guatemala for the first time. The sex of the holotype of Lamacoscylus albatus Martins, Santos-Silva and Galileo, 2015, is corrected, and a new state record in Mexico is provided. The description of the antennae in females of Lamacoscylus Martins and Galileo,1991 is discussed; Malacoscylus humilis Bates,1881 (currently Lamacoscylus humilis) sensu Gahan (1892) is discussed and the two varieties described by him, M. humilis var. fulvescens and M. humilis var. grisescens (only part of the speci-mens), as well as M. usingeri Linsley,1935 are transferred to Schmidarius Santos-Silva, Heffern, Botero and Nascimento, new genus. Additionally, a new species from Mexico (Mexico) is described in Schmidarius as S. kondratieffi Santos-Silva, Heffern, Botero and Nascimento. The correct type-species of Phoebe Audinet-Serville,1835 is determined as Saperda bicornis Olivier,1800 and Phoebe phoebe Lepeletier and Audinet-Serville,1825 and Phoebe tinga Martins and Galileo,1998 are transferred to Phoebella Lane,1966, which is redescribed. Leucophoebe Lane,1976 is synonymized with Phoebe. A key to species of Hemilophini with 12-segmented antennae is provided. The differences between Callanga Lane,1973 and Lapazina Lane,1973 are discussed, and a new species of Callanga from Peru is described as C. ashaninka Santos-Silva, Heffern, Botero and Nascimento. A new species of Fredlanea Martins and Galileo,1996 from Colombia is described as F. lazulina Santos-Silva, Heffern, Botero and Nascimento; a new department record in Colombia is provided for Fredlanea consobrina (Lane,1970) and a chromatic variation in this species is discussed.
