A new species of Chrysina Kirby, C. clavellina Monzón, Blackaller, and Hawks (Coleoptera: Scarabaeidae: Rutelinae: Rutelini) is described from Santiago Clavellinas in the Sierra Azul in Oaxaca, Mexico. Chrysina cosijoezai (Ramírez-Ponce and Curoe) is placed as a junior synonym of C. lacordairei (Boucard), and notes on the Chrysina fauna of this mountain range are included.
Psyllids are an economically important group of insects. Several species are serious emerging pests with regulatory significance. About 20 adventive species have been discovered in Florida in the past 20 years, including several pests. Additionally, five species new to science have been found. We provide an annotated checklist of Florida species with taxonomic information and identification tools, including keys to Florida genera and known species. Seventy species of Psylloidea currently are reported from Florida. Forty-one are native to Florida, with 12 endemic to the state. Twenty are adventive, the majority being from the Neotropics. One was introduced deliberately for biological control, seven represent temporary populations (eradicated, reared in quarantine), and one is a dubious record. Craspedolepta euthamiae Burckhardt and Halbert, new species, Katacephala wineriterae Burckhardt and Halbert, new species, Pseudophacopteron gumbolimbo Burckhardt and Halbert, new species, Nothotrioza longipedis Burckhardt and Halbert, new species, and Trioza myresae Burckhardt and Halbert, new species are described from Florida and are native endemic species. Aphalara persicaria Caldwell is redescribed and separated from similar species. Aphalara persicaria var. cubana Caldwell is confirmed as a junior synonym of Aphalara persicaria. The Florida records of Craspedolepta spp. are revisited and revised, including Craspedolepta euthamiae Burckhardt and Halbert, new species. Bactericera nigrilla (Crawford), new combination, revived status is recognized from Florida, redescribed, and distinguished from similar species. Rhinopsylla caldwelli Tuthill is transferred to Kuwayama Crawford and becomes Kuwayama caldwelli (Tuthill), new combination.Trioza maritima Tuthill is transferred to Leuronota Crawford and becomes Leuronota maritima (Tuthill), new combination. Species of Bactericera Puton on Salix L. (Salicaceae) in North America are reviewed. Bactericera flori (Crawford), new combination, new status. is determined to be the correct name for Trioza assimilis Crawford nec Flor (= Trioza flori Crawford, replacement name, = Trioza pomonae Aulmann, replacement name), and Trioza dubia Patch, new synonym. Lectotypes are designated for Trioza marginata Crawford, Trioza minuta Crawford, Trioza minuta similis Crawford, and Trioza nigra Crawford.
A new millipede species of the genus Sechelleptus Mauriès, 1980 is described and illustrated from Mayotte Island, Indian Ocean. This new species, S. arborivagus sp. nov., found on trees, looks particularly similar to the sympatric S. variabilis VandenSpiegel & Golovatch, 2007, but is much larger and has a very different ecological behavior. Phylogenetic analyses based on a concatenated dataset of the COI and 16S rRNA genes and including nine species of Spirostreptidae (including Sechelleptus, Doratogonus Attems, 1914, Bicoxidens Attems, 1928 and Spirostreptus Brandt, 1833), strongly support the monophyly of Sechelleptus. Despite the similarity of their genitalia, the molecular analyses also reveal a clear-cut genetic divergence between S. arborivagus sp. nov. and S. variabilis (22.55% for COI and 6.63% for 16SrRNA) and further suggest the presence of a higher diversity within the genus Sechelleptus on Mayotte.
An annotated list of twenty species of rarely collected and little known bees of the genus Sphecodes Latreille, 1804 (Hymenoptera: Apoidea: Halictidae) from the Himalayas is given. Sphecodes bluethgeni sp. nov. is described from Bhutan. Three species are newly recorded from the Himalayas: S. binghami Blüthgen, 1924, S. kershawi Perkins, 1921 and S. laticeps Meyer, 1920. Based on type specimens, new synonymies have been proposed for Sphecodes cameronii (Bingham, 1897) = S. armeniacus Warncke, 1992 syn. nov.; S. gibbus (Linnaeus, 1758) = S. indicus Bingham, 1898 syn. nov.; and S. invidus (Cameron, 1897) = S. nigrobasalis Meyer, 1922 syn. nov. A lectotype is designated for Sphecodes sikkimensis Blüthgen, 1927. Illustrated keys to males and females of all species known from the Himalayas and an updated checklist of the 26 Himalayan species of Sphecodes are provided. Additionally, one new species from neighboring Uttar Pradesh (India), Sphecodes uttaricus sp. nov., is here described as new and included due to its close relationship to the Himalayan S. sikkimensis Blüthgen, 1927.
A new species of the genus Mesobiotus is described from the Republic of South Africa using a traditional morphological approach (light and scanning electron microscopy) combined with molecular analysis (18S rRNA, 28S rRNA, ITS-2 and COI markers). Mesobiotus anastasiae sp. nov. differs from all known Mesobiotus species by having a unique combination of characters of the adult animals and the eggs. Adults of the new species have an oral cavity armature without elongate teeth in the second band, while the processes of the egg chorion have a basal collar and distinct rows of large pores. An updated key to the species of the genus Mesobiotus, including 66 of 70 currently described species, is given. An aquatic mite species from the Lobohalacarus weberi complex (freshwater Halacaridae) co-occurs with M. anastasiae sp. nov., suggesting that the newly described tardigrade inhabits constantly wet moss cushion habitats.
The taxonomic and faunistic status of the spider family Oecobiidae in Iran, Afghanistan and Turkmenistan is revised. A new species, namely Uroctea gambronica sp. nov. (♂) is described from southern Iran, and the male of U. grossa Roewer, 1960 is described and illustrated for the first time. Additionally, new faunistic data are provided, including the first records of Oecobius putus O. Pickard-Cambridge, 1876 and U. grossa in Afghanistan and Turkmenistan, respectively, and the re-evaluation of previously misidentified and questionable records of this family in the region. The known distribution ranges of all species are mapped for these three countries.
Pholetesor acrocercophagus sp. nov., P. camerariae sp. nov. and P. indicus sp. nov.(Hymenoptera: Braconidae: Microgastrinae) are described as new to science. These three species were reared from Acrocercops sp., Acrocercops phaeospora Meyrick, 1916 and Cameraria virgulata Meyrick, 1914 (Lepidoptera: Gracillariidae), respectively. Characteristics of these new species and their affinities with related taxa are discussed. Data on habitat, host records and host plant species for all the parasitoid species is provided. A key to the Indian species of the genus Pholetesor Mason, 1981 reared from lepidopteran leafminers is also given.
Sweat bees in the subgenus Lasioglossum (Dialictus) are one of the most diverse and abundant bee taxa, and a critically important component of bee biodiversity. Yet, the most basic taxonomic knowledge of these bees is lacking in many regions. As a step towards a better understanding of the L. (Dialictus) of the western Nearctic region, a revision of the ‘red-tailed’ L. (Dialictus) species was completed. Thirty-six species were revised, 20 of which are described as new, and two names are treated as junior subjective synonyms. Descriptions, figures, distribution maps, floral hosts, and keys to species for females and males are provided. The following 20 species are described as new: Lasioglossum (Dialictus) arenisaltans sp. nov., L. (D.) argammon sp. nov., L. (D.) austerum sp. nov., L. (D.) cactorum sp. nov., L. (D.) cembrilacus sp. nov., L. (D.) clastipedion sp. nov., L. (D.) clavicorne sp. nov., L. (D.) decorum sp. nov., L. (D.) festinum sp. nov., L. (D.) imbriumbrae sp. nov., L. (D.) julipile sp. nov., L. (D.) lilianae sp. nov., L. (D.) meteorum sp. nov., L. (D.) miltolepoides sp. nov., L. (D.) minckleyi sp. nov., L. (D.) perditum sp. nov., L. (D.) rufornatum sp. nov., L. (D. ) spivakae sp. nov., L. (D.) tessellatosum sp. nov., and L. (D.) torrens sp. nov. Previously unknown males of L. (D.) clematisellum (Cockerell, 1904), L. (D.) droegei Gibbs, 2009, L. (D.) kunzei (Cockerell, 1898), and L. (D.) pallidellum (Ellis, 1914) are described and figured for the first time. Lasioglossum (Dialictus) clarissimum (Ellis, 1914) (= Halictus clarissimus Ellis, 1914) and L. (D.) perexiguum (Sandhouse, 1924) (= Halictus (Chloralictus) perexiguus Sandhouse, 1924) are new subjective junior synonyms of L. mesillense (Cockerell, 1898) (= Halictus nymphalis var. mesillensis Cockerell, 1898). A lectotype specimen is newly designated for L. mesillense, for which the location of the type material has not previously been known. The following five new records for Mexico are reported: L. clematisellum, L. droegei, L. eophilus (Ellis, 1914), L. kunzei, and L. pallidellum.
