Twenty-nine species of caddisflies in the genus Agapetus Curtis in eastern and central North America are reviewed. Twelve are described as new species: Agapetus aphallus (known only from females); Agapetus baueri, Agapetus flinti, Agapetus harrisi, Agapetus hesperus, Agapetus ibis, Agapetus kirchneri, Agapetus meridionalis, Agapetus pegram, Agapetus ruiteri, Agapetus stylifer, and Agapetus tricornutus. Agapetus rossi Denning 1941 is recognized as a junior subjective synonym of Agapetus walkeri (Betten and Mosely 1940), new synonym. A key to males is provided, and species’ distributions are mapped.
The Neotropical ambrosia beetle genus Camptocerus Dejean was revised. Monophyly of the genus was tested using 66 morphological characters in a cladistic analysis. Camptocerus was recovered as monophyletic and 31 species were recognized. Six new synonyms were discovered: C. auricomus Blandford 1896 (= C. striatulus Hagedorn 1905), C. inoblitus (Schedl) 1939 (= C. morio (Schedl) 1952), C. niger (Fabricius) 1801 (= C. tectus Eggers 1943), C. opacicollis (Eggers) 1929 (= C. infidelis Wood 1969; = C. uniseriatus Schedl 1972), C. suturalis (Fabricius) 1801 (= C. cinctus Chapuis 1869). Two species were removed from synonymy: C. charpentierae Schedl and C. hirtipennis Schedl. Twelve new species of Camptocerus were described: C. coccoformus (Brazil, Ecuador), C. distinctus (Ecuador), C. doleae (Ecuador), C. igniculus (Brazil), C. mallopterus (Ecuador), C. noel (widely distributed across Amazonia), C. petrovi (Ecuador), C. pilifrons (Ecuador), C. pseudoangustior (widely distributed across Amazonia), C. satyrus (Brazil), C. unicornus (Brazil) and C. zucca (Ecuador). Lectotypes are here designated for the following species: Camptocerus auricomus Blandford, Camptocerus squammiger Chapuis, Hylesinus gibbus Fabricius, Hylesinus suturalis Fabricius, Hylesinus fasciatus Fabricius. A key, diagnosis, distribution, host records and images were provided for each species.
We provide new records of biting and predaceous midges (Diptera: Ceratopogonidae) from Florida, including the first documented United States records of Atrichopogon (Atrichopogon) caribbeanus Ewen, Dasyhelea griseola Wirth, D. scissurae Macfie, and Brachypogon (Brachypogon) woodruffi Spinelli and Grogan. Atrichopogon (Meloehelea) downesi Wirth, Forcipomyia (Thyridomyia) monilicornis (Coquillett), F. (T.) nodosa Saunders, Ceratoculicoides blantoni Wirth and Ratanaworabhan, Mallochohelea albibasis (Malloch), Bezzia (Bezzia) imbifida Dow and Turner and B. (B.) mallochi Wirth are recorded for the first time from Florida. Forcipomyia (Thyridomyia) johannseni Thomsen, Bezzia (Bezzia) expolita (Coquillett), and B. (B.) pulverea (Coquillett) are deleted from the ceratopogonid fauna of Florida. Dasyhelea koenigi Delécolle and Rieb is a junior objective synonym of Dasyhelea scissurae Macfie (NEW SYNONYM). The total number of Ceratopogonidae recorded from Florida is now 249 species contained within 27 genera.
Homophileurus neptunus Dechambre was found to be conspecific with H. waldenfelsi Endrödi after examination of types, descriptions, and illustrations. Accordingly, H. neptunus is placed in junior synonymy with H. waldenfelsi, new synonymy. Homophileurus waldenfelsi is an uncommon species and occurs in Ecuador, Colombia, Brazil, and Peru. Brazil and Peru are new country records.
This paper summarizes the information published on the beetle fauna of the island of St. Vincent (excluding the Grenadine islands). The fauna contains 62 families, with 371 genera, and 536 species. The families with the largest number of species are Staphylinidae (128), Curculionidae (54), Chrysomelidae (47), Scarabaeidae (31), Tenebrionidae (30), and Cerambycidae (29). At least 17 species (3.17%) were probably accidentally introduced to the island by human activities. One hundred four species (19.40%) are endemic (restricted) to the island and likely speciated on the island. One hundred twenty species (22.39%) are shared only with other islands of the Lesser Antilles (Lesser Antillean endemics), and 41 species (7.65%) are more widespread Antilles endemics. The remaining 254 species (47.38%) in the fauna are otherwise mostly widely distributed in the Antilles and the Neotropical Region. The St. Vincent beetle fauna has thus mostly originated elsewhere than on St. Vincent and is largely an immigrant fauna from other islands of the West Indies or the continental Neotropics. Of the St. Vincent species known to occur on other islands, the largest numbers are shared with (north to south) Guadeloupe (206), Dominica (115), Martinique (76), St. Lucia (87) and Grenada (298). Undoubtedly, the real number of species on St. Vincent is higher than now reported and may actually be around 1200 or more species.
Review of Synapsis Bates (Scarabaeidae: Scarabaeinae: Coprini), with description of a new species
(2010)
Presented are a checklist, a discussion of and keys to species groups and their constituent species, and a description of one new species: Synapsis horaki. The species Synapsis cambeforti Krikken and S. thoas Sharp are synonymized with S. ritsemae Lansberge, Balthasar’s synonymy of S. yunnana Arrow with S. tridens Sharp is revived, and the status of six recently described species is left unresolved because of insufficient data.
Six new species of the weevil genus Cercopeus Schoenherr are described from South Carolina: C. alexi, C. cornelli, C. femoratus, C. paulus, C. skelleyi, and C. tibialis. Three other species also found in South Carolina are redescribed: C. chrysorrhoeus (Say), C. maspavancus Sleeper, and C. strigicollis Sleeper. Keys to known males and females of all 17 species of Cercopeus are given, along with photographs of habitus, leg features, and antennae, and line illustrations of genitalia. Nearly all specimens of the new species were collected from January-March and these species are winter active.
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.
