Three species in one: a revision of Clemensiaalbata Packard (Erebidae, Arctiinae, Lithosiini).

Clemensiaalbata Packard, previously thought to be a single, widely distributed North American species, is here shown to consist of three distinct, primarily parapatric species: Clemensiaalbata Packard, C.umbrata Packard, stat. rev., and Clemensiaochreata Schmidt & Sullivan, sp. n. Adults and genitalic structures of the three species are illustrated.

A revision of the genus Doryodes Guenée, 1857, with descriptions of six new species (Lepidoptera, Erebidae, Catocalinae, Euclidiini).

The genus Doryodes Guenée is revised to include ten species including six species described as new (Doryodes desoto Lafontaine & Sullivan; Doryodes okaloosa Sullivan & Lafontaine; Doryodes fusselli Sullivan & Lafontaine; Doryodes reineckei Sullivan & Lafontaine; Doryodes broui Lafontaine & Sullivan; and Doryodes latistriga Sullivan & Lafontaine). A key to species, descriptions, and illustrations of adults and genitalia are included.

The Phyllodonta latrata (Guenée) species group in Costa Rica (Geometridae, Ennominae).

Historically, the name Phyllodonta latrata (Guenée) has been applied to what is a complex of three undescribed species in Costa Rica. They are very similar in maculation, but can be differentiated by genitalic characters and barcodes. P. alajuela Sullivan, sp. n. occurs at lower altitudes in the northwestern part of Costa Rica whereas P. intermediata Sullivan, sp. n. and P. esperanza Sullivan, sp. n. are found at partially overlapping altitudes in the central mountain ranges.

The Disphragis notabilis (Schaus) species-group in Costa Rica (Lepidoptera, Notodontidae).

The four described taxa in the Disphragis notabilis (Schaus) species-group are reviewed, including the types and their dissected genitalia. Disphragis hemicera (Schaus), stat. rev., is elevated to species rank, D. normula (Dognin) is retained as a synonym of D. notabilis, D. sobolis Miller is confirmed as distinct from D. hemicera, and D. bifurcata sp. n., is newly described. Both D. hemicera and D. bifurcata occur in Costa Rica. The known ranges of the other species are outlined. Defining characters of each species are presented and a key to species is provided. Unusual variation in the genitalia is noted.

A new apameine genus and species from the southern Appalachian Mountains, USA (Lepidoptera, Noctuidae, Noctuinae).

Cherokeea gen. n. is proposed for a rarely collected apameine moth species from the southern Appalachian Mountains, C. attakullakulla sp. n. It is recorded from foothills and lower montane habitats of North Carolina and Georgia where hill cane, Arundinaria appalachiana Triplett, Weakley & L.G. Clark is found. Adults and their genitalia are figured and a mtDNA barcode sequence is given.

A new species of Palpita (Crambidae, Spilomelinae) from the coastal plains of southeastern United States.

A new species of Palpita Hübner (Crambidae, Spilomelinae), Palpita maritima, sp. n., is described from maritime forests of the coastal plains of southeastern United States.

Two new species of the Hagnagora anicata complex (Geometridae, Larentiinae) from Costa Rica.

Examination of the lectotype (here designated) reveals that Hagnagora anicata (Felder & Rogenhofer) does not occur in Costa Rica. Instead two new species are described, Hagnagora eliannesp. n. and Hagnagora unniasp. n., and their distribution is discussed. The previous treatment of Hagnagora anicata as a single widespread species ranging from Jamaica and Mexico to Bolivia needs to be critically evaluated.

The genus Neotherina Dognin (Geometridae, Ennominae) in Costa Rica.

So far, two species of Neotherina Dognin have been recorded in Costa Rica. Neotherina imperilla (Dognin) occurs primarily at altitudes between 1100 and 1700 meters and Neotherina callas (Druce) which is widely distributed above 1100 meters. A third, new species, Neotherina xanthosa Sullivan and Chacón is described from altitudes above 2400 meters. Heterogeneity of the genus is discussed.

Gondysia preceded Neadysgonia (Lepidoptera, Erebidae, Erebinae), a new generic synonymy from southeastern United States.

The recently proposed genus Neadysgonia Sullivan, 2010, was preceded in the literature by Gondysia Berio, 1955, a monotypic genus based on specimens without locality labels but presumed to be from Madagascar. The genus Gondysia replaces Neadysgonia and the species Gondysia pertorrida Berio, 1955, becomes a junior synonym of Gondysia consobrina (Guenée, 1852).

New synonymies and combinations in Argyrostrotis Hübner (Lepidoptera, Erebidae, Erebinae, Poaphilini).

After examining the type specimens of species in the eastern North American genus Argyrostrotis the number of known species in the genus is reduced from 10 to six through synonymy. A key to species is included along with illustrations of the adults and genitalia of each species. Three Neotropical species currently included in Argyrostrotis (Argyrostrotis eurysaces Schaus, 1914; Argyrostrotis quadrata Dognin, 1910; and Celiptera surrufula Dyar, 1913) are transferred to other genera as Argyrosticta eurysaces (Schaus, 1914), comb. n. [Noctuidae: Bagisarinae], Heterochroma quadrata (Dognin, 1910), comb. n. [Noctuidae: Amphipyrinae], and Ptichodis surrufula (Dyar, 1913), comb. n. [Erebidae: Erebinae: Euclidiini].

Integration of DNA barcoding into an ongoing inventory of complex tropical biodiversity.

Inventory of the caterpillars, their food plants and parasitoids began in 1978 for today's Area de Conservacion Guanacaste (ACG), in northwestern Costa Rica. This complex mosaic of 120 000 ha of conserved and regenerating dry, cloud and rain forest over 0-2000 m elevation contains at least 10 000 species of non-leaf-mining caterpillars used by more than 5000 species of parasitoids. Several hundred thousand specimens of ACG-reared adult Lepidoptera and parasitoids have been intensively and extensively studied morphologically by many taxonomists, including most of the co-authors. DNA barcoding - the use of a standardized short mitochondrial DNA sequence to identify specimens and flush out undisclosed species - was added to the taxonomic identification process in 2003. Barcoding has been found to be extremely accurate during the identification of about 100 000 specimens of about 3500 morphologically defined species of adult moths, butterflies, tachinid flies, and parasitoid wasps. Less than 1% of the species have such similar barcodes that a molecularly based taxonomic identification is impossible. No specimen with a full barcode was misidentified when its barcode was compared with the barcode library. Also as expected from early trials, barcoding a series from all morphologically defined species, and correlating the morphological, ecological and barcode traits, has revealed many hundreds of overlooked presumptive species. Many but not all of these cryptic species can now be distinguished by subtle morphological and/or ecological traits previously ascribed to 'variation' or thought to be insignificant for species-level recognition. Adding DNA barcoding to the inventory has substantially improved the quality and depth of the inventory, and greatly multiplied the number of situations requiring further taxonomic work for resolution.
