Generic Rank

Over a century ago in his memoir on Gorytes, Lepeletier proposed Lestiphorus for the reception of Rossi's distinctive European species Crabro bicinctus. However, very few subsequent authors have recognized it as a discrete generic entity. It has generally been regarded as merely a species group or occasionally treated as a subgenus of Gorytes or some related genus. But Lestiphorus, although small, is indubitably entitled to full generic rank.

Tubpontania gen. nov. (type species Nematus anomalopterus Förster, 1854), is proposed for the species of the former Pontania crassispina group. Tubpontania anomaloptera (Förster, 1854), comb. nov., = Amauronematus maidli Zirngiebl, 1937, syn. nov., = Nematus (Pontania) tuberculatus Benson, 1953, syn. nov. Other European species of the genus are Tubpontania cyrnea (Liston, 2005) (= Pontania joergenseni Enslin, 1916, syn. nov.; preoccupied by Pontania jörgenseni Strand, 1908), Tubpontania crassispina (Thomson, 1871), comb. nov., Tubpontania purpureae (Cameron, 1884), comb. nov., and Tubpontania nudipectus (Vikberg, 1965), comb. nov. Tubpontania nitidinota sp. nov., closely related to T. nudipectus, is described from Fennoscandia. Furthermore, the following North American species belong here: Tubpontania arctophilae (Benson, 1960), comb. nov., Tubpontania populi (Marlatt, 1896), comb. nov., Tubpontania pumila (Rohwer, 1910), comb. nov., Tubpontania rotundidentata (Zinovjev & Vikberg, 1999), comb. nov. and Tubpontania terminalis (Marlatt, 1896), comb. nov.

AbstractThe North American species of Lauxania Latreille are revised. The genus contains five Nearctic species: L. albiseta Coquillett, L. glabrifronssp.nov., L. kafaristasp.nov., L. nigrimana Coquillett, and L. shewellisp.nov. All Nearctic species are illustrated and keyed. Consistent genitalic differences between Nearctic and Palaearctic specimens of the species usually identified as Lauxania cylindricornis (Fabricius) justify the recognition of the Nearctic specimens as a distinct species (L. shewelli). The male genitalia of Lauxania represent two types: the apparently plesiomorphic type has a simple rodlike phallapodeme, membranous phallus, and pointed unbranched postgonites; the apomorphic type has the phallapodeme expanded into a sclerotized hood surrounding the base of the phallus, a convoluted sclerotized phallus, and branched postgonites. These two genitalic types also occur in the related genus Calliopum Strand, which provides strong evidence that these genera, as currently recognized, may not be monophyletic relative to one another.

The Individual

The results are given of a survey of the cestode fauna of several thousand fishes representing thirty species common in the Hudson bay drainage system, particularly in the Hudson bay and in the larger lakes of Manitoba and Saskatchewan. The survey yielded twelve species of adult and seven species of larval cestodes, ten of which were identical with European species, while seven were purely North American. The incidence of infection was high and the individual intensity was heavy. The highest incidence and heaviest intensity occurred among nektonic types such as Hiodon, Leucichthys, Esox, Lucioperca and Salvelinus. Benthonic forms such as Catostomus, Ameiurus, Lota, Acipenser and Coregonus, were found relatively free from infection.The North American species of Cyathocephalus and Diplocotyle are regarded as identical with the European species C. truncatus and D. Olrikii; the species C. americanus Cooper, and Bothrimonus intermedius Cooper are rejected. The triaenophorid common in the area is regarded as Triaenophorus tricuspidatus (Bloch), and two morphae are recognized, microdentatus and megadentatus, the latter equivalent to T. robustus (Olsson). Bothriocephalus cuspidatus Cooper is regarded as comprising three sub-species, cuspidatus, hiodontos and luciopercae. The eubothriid cestode in Lota lota maculosa is regarded as identical with the European E. rugosum, but comprising two morphae, conformatus and deformatus. Two new species of Proteocephalus are described, namely coregoni from Coregonus atikameg, and luciopercae from Lucioperca vitreum.

AbstractThe species of the genus Entomacis Foerster in North America north of Mexico are revised. Nineteen species (12 new), including 8 species of the Holarctic-wide perplexa species group, are keyed, described, and figured. These taxa are E. ambigua (Brues), E. apopkaensissp. nov., E. arcticasp. nov., E. cellariasp. nov., E. cepasp. nov., E. eorariasp. nov., E. floridana (Ashmead), E. grandiclavasp. nov., E. longii (Ashmead), E. mellipetiola (Ashmead), E. parambiguasp. nov., and perplexa group members E. californica (Ashmead), E. microbipunctatasp. nov., E. notioxerasp. nov., E. oulasp. nov., E. parvasp. nov., E. perplexa (Haliday), E. sapratasp. nov., and E. subemarginata (Ashmead). Hemilexodes canadensis (Harrington) is synonymized under Entomacis mellipetiola (Ashmead) (syn. nov.). The status of Entomacis latipennis (Ashmead), E. filiformis (Ashmead), and Hemilexis jessei Mann is reviewed. New character complexes, particularly chaetotaxy, are emphasized for Diapriidae species taxonomy.

The north-western European species of the laevigatus-group of Apanteles are revised. Forty species are dealt with, of which twenty are described as new. Brief notes are added on North American species of the group in the British Museum (Nat. Hist.) to assist their eventual correlation with the European species.

Mr. Neumoegen and myself are at work upon this genus, with a view to present a revision of it; there are, however, some points upon which I should like to make a few independent remarks. The genus Halisidota is exclusively American, its stronghold being in the South. Indeed, the whole sub-family, the Phægopterinæ, are strongly, American, there being no European species and but few African, While still fewer reach through the East Indies to Australia.

Subjective Synonym

The larva of Epeorus punctatus (McDunnough) is described for the first time based on reared specimens from West Virginia. Larvae are differentiated from those of other E. vitreus species group species by the bluntly pointed femoral projections, subrectangular head capsule, and short posterolateral abdominal projections. Epeorus rubidus (Traver) is considered to be a junior subjective synonym of E. vitreus (Walker). A key for the known larvae of the eastern North American species of the E. vitreus species group [E. dispar (Traver), E. punctatus, E. subpallidus (Traver), E. vitreus] is provided.

AbstractDescriptions of Procloeon rubropictum (McD.), P. quaesitum (McD.), and P. rufostrigatum (McD.) are expanded to include features not previously published. A description of the nymph of P. quaesitum is given for the first time. Procloeon irrubrum sp.nov. is described from nymphs and female imagoes. From our interpretation of preliminary data, it is possible that P. rufostrigatum and P. rubropictum form one species group; P. quaesitum is included with P. pennulatum (Eaton) in another. Procloeon irrubrum does not fit either species group but shows some affinities to the P. rufostrigatum group. Some characters for separating the nymphs of Procloeon and Centroptilum are given.

A New Species

DNA barcoding is used to verify characters to morphologically differentiate genetically distinct species of eastern North American small carpenter bees, Ceratina. Here we reveal that the common eastern North American species, Ceratina dupla s. l., is actually three separate species based on fixed differences in DNA barcode sequences and morphological characters. This study adds a new species, C. mikmaqi Rehan & Sheffield, to the Ceratina dupla species-group of eastern North America, and raises another form, C. floridana formerly C. dupla floridana, to full species. Temporal niche partitioning between C. dupla and C. mikmaqi and geographic isolation of C. floridana further support the division of the C. dupla s. l. group into three species. A diagnosis and description of the new species are provided, as is a key for eastern North American species of Ceratina.
