A New Species

Parastenocaris brevipes Kessler is redescribed and its presence in North America is established through comparison of specimens from the U.S.A., Finland, and Germany. Parastenocaris wilsoni Borutskii, Parastenocaris starretti Pennak, Parastenocaris biwae Miura, and Parastenocaris sp. 2 Strayer (Strayer, D.L. 1988. Stygologia, 4: 279–291.) are assigned to the synonymy of P. brevipes. Biwaecaris Jakobi is a synonym of Parastenocaris Kessler. Some North American records of P. brevipes or P. starretti refer in fact to P. brevipes, other records to a presently undescribed species. Newly verified records of P. brevipes include Massachusetts, Michigan, New Hampshire, New York, Virginia, and Wisconsin in the U.S.A., and Lake Biwa, Japan. Parastenocaris trichelata, new species, is described from Virginia, U.S.A. The taxon is distinguished in both sexes by the combination of the long slender caudal ramus with all setae inserted in the distal half and by the medial spine of the leg 1 basipodite, and in the male by the leg 4 with slender hyaline endopodite and 3 spines on the basipodite medial to the endopodite. The new species little resembles any known North American parastenocaridid, nor is it assignable to any presently defined species-group in the genus.

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.

<em><strong>Colletes ultravalidus</strong></em> Hall &amp; Ascher, new species, is described from several sites in northwestern Florida and southeastern Georgia.  It is a member of the <em>inaequalis</em> species group, very similar to <em>C. validus</em> Cresson, a specialist of Ericaceae, but can be distinguished by an even more elongate malar area and the absence of conspicuous tergal fascia.  <em>Colletes ultravalidus</em> has been found flying from early winter to early spring when it forms nest aggregations in xeric sites adjacent to shrub bog or basin swamp, the habitat of <em>Pieris phyllyreifolia</em> (Hook.) DC. (Ericaceae), the most likely, but as yet unconfirmed, host plant of the new species.  State records of Colletes for Florida and Georgia are reviewed and discrepancies in taxonomy and distributional limits between Stephen’s 1954 revision of the genus and Mitchell’s 1960 monograph of eastern North American bees are noted.  We concur with Stephen that the distributions of several taxa in <em>Colletes</em> are more limited than that reported by Mitchell.

AbstractThe genusDyschiriusincludes 56 North American species which are arranged in 13 species groups. Keys are provided for the species groups and the species. Four new species are described:D.sculptusBousquet (type locality: Pass-a-Grille Beach, Florida);D.ferrugineusBousquet (type locality: Goose Island State Park, Texas);D.larochelleiBousquet (type locality: 6 mi. S Lake Placid, Florida); andD.comatusBousquet (type locality: Highlands Hammock, Florida). Six species names are placed in synonymy for the first time. They are (with the junior synonym listed first):D.arizonicusVan Dyke 1943 =D.interiorFall 1922;D.duplicatesFall 1901 =D.affinisFall 1901;D.desertusFall 1925 =D.perversusFall 1922;D.subpunctatusHatch 1949 =D.sphaericollis(Say 1825);D.basalisLeConte 1857 andD.transmarinusMannerheim 1853 =D.integerLeConte 1851. The adult and larval character states of the genus are listed and comments are provided for each species group.

AbstractNorth American members of the Liodessus affinis (Say 1823) species complex are revised. The species group comprises four species. Two new species are described: L. noviaffinis (type locality: Gainesville Forest Insect Lab, Alachua Co., Florida) and L. saratogae (type locality: Saratoga Springs, San Bernardino County, California). Liodessus obscurellus (LeConte 1852), formerly considered a junior subjective synonym of L. affinis, is given specific status. The following synonymies are established: L. affinis microreticulatus (Hatch 1928), L. charlottii (Clark 1862), L. emilianus (Clark 1862), L. erythrostomus (Mannerheim 1852), L. macularis (LeConte 1852), and L. nigrinus (Casey 1884) = L. obscurellus. All of these names were previously treated as junior subjective synonyms of L. affinis. Also, L. youngi (Larson & Roughley 1990) = L. abjectus (Sharp 1882). Lectotypes are designated for L. abjectus, L. charlottii, L. erythrostomus, L. emilianus, L. macularis, L. nigrinus, and L. obscurellus. A neotype is designated for L. affinis. Liodessus nanus (Aubé 1838) is considered a species name of uncertain status, but is probably a subjective synonym of L. affinis. A key is provided for the nine known species of North American Liodessus Guignot. The genus Liodessus is diagnosed, and its taxonomic history and questionable status as a natural group are discussed. The L. affinis complex is diagnosed, and its taxonomic history and natural history are discussed. Male genitalia are the only consistently useful structures known for differentiating species in the L. affinis complex. Females are not distinguishable based on currently known morphological features but may be identified using geographic information. Characters used previously, including coloration, punctation and general shape are too variable within and between species to be useful for species diagnosis or delimitation. For each species in the complex the following are provided: a bibliography of the species, discussion of type specimens, taxonomic history and synonymy, diagnosis, variation, etymology (for new species), geographic relationships, natural history, and geographic distribution. Distribution maps and illustrations of important structural features are provided for all species of the complex. For other Nearctic species of Liodessus the following are provided: a brief bibliography of the species, diagnosis, distribution, remarks about bionomics and/or taxonomy, and illustrations of important structural features.

The genus Leptodrepana Shaw was described in 1983, but prior to the current study only one Neotropical species had been described from Mexico and none were named from Costa Rica. In this paper twenty-four new species are described and named from Costa Rica: L.alexisae Dadelahi &amp; Shaw, sp. n., L.atalanta Dadelahi &amp; Shaw, sp. n., L.conda Dadelahi &amp; Shaw, sp. n., L.conleyae Dadelahi &amp; Shaw, sp. n., L.demeter Dadelahi &amp; Shaw, sp. n., L.eckerti Dadelahi &amp; Shaw, sp. n., L.gauldilox Dadelahi &amp; Shaw, sp. n., L.hansoni Dadelahi &amp; Shaw, sp. n., L.kimbrellae Dadelahi &amp; Shaw, sp. n., L.lorenae Dadelahi &amp; Shaw, sp. n., L.munjuanae Dadelahi &amp; Shaw, sp. n., L.ninae Dadelahi &amp; Shaw, sp. n., L.pamelabbas Dadelahi &amp; Shaw, sp. n., L.ronnae Dadelahi &amp; Shaw, sp. n., L. rosanadana Dadelahi &amp; Shaw, sp. n., L.schuttei Dadelahi &amp; Shaw, sp. n., L.scottshawi Dadelahi, sp. n., L.shriekae Dadelahi &amp; Shaw, sp. n., L.sohailae Dadelahi &amp; Shaw, sp. n., L.sorayae Dadelahi &amp; Shaw, sp. n., L.soussanae Dadelahi &amp; Shaw, sp. n., L.stasia Dadelahi &amp; Shaw, sp. n., L.strategeri Dadelahi &amp; Shaw, sp. n., and L.thema Dadelahi &amp; Shaw, sp. n. A key to Costa Rican species of Leptodrepana is provided. The flagellum of all female Leptodrepana described in this work is reduced to only 17 flagellomeres. This character state is also found in two North American species described by Shaw (1983), L.opuntiae Shaw and L.oriens Shaw. It is hypothesized that a female antenna with 17 flagellomeres is a synapomorphy for a species-group comprising all the Costa Rican Leptodrepana species as well as two of the Mexican and North American species, L.opuntiae and L.oriens.
