Based on the examination of 4,218 slide-mounted preparations of male and female genitalia of tortricine moths, representing all major clades of the subfamily worldwide, we propose a classification system for cornuti based on four criteria: (1) presence/absence; (2) deciduous/non-deciduous; (3) type of attachment; and (4) shape. In general, the taxonomic distribution of deciduous versus non-deciduous cornuti is in conformance with a recent phylogenetic hypothesis of the family. Some sister groups (i.e., tribes) have remarkably similar cornuti (e.g., Atteriini and Sparganothini); however, between other sister groups, features of the cornuti (presence/absence, attachment, shape, size, etc.) provide little or no evidence of putative relationships (e.g., Ceracini and Archipini). Our studies suggest that if deciduous cornuti are homologous throughout Tortricidae, which seems likely, this feature arose near the base of the tree at the branch that supports the sister groups Olethreutinae + Tortricinae. The least derived Tortricinae (i.e., Phricanthini) possess typical deciduous cornuti as do most Archipini, Sparganothini, and Atteriini, and some Epitymbiini (Tortricinae), as well as some Eucosmini and Grapholitini (Olethreutinae).
We sampled a juniper-oak-grassland habitat in southeastern Arizona for Symphyta over a seven-year period. Collections included 27 species of Symphyta: 1 Xyelidae, 5 Pergidae, 1 Diprionidae, 16 Argidae, and 4 Tenthredinidae. The peak season for sawflies is July through September, coinciding with the rainy season. Five new species are described, Acordulecera brevis Smith,A. tristis Smith, and A. comoa Smith (Pergidae), and Eustromboceros arizonicus Smith and E. alboclypea Smith (Tenthredinidae). Previously unknown males are described for Sphacophilus apiculus Smith, Zynzus luteiventris (Cameron) (Argidae), and Susana rufa Smith (Tenthredinidae). Zynzus himus Smith is a new record for the United States, and Periclista is a new generic record for Arizona.
Two new species of Incawockia, I. rubiginosa,newspecies from Costa Rica and I. samba,newspecies from Brazil, are described and illustrated. Morphological features of two new species, including the median lobe of the gnathos and the elongate saccular process with an apical spine, help to further define Incawockia.
A new species from the Philippines closely related to the emerald ash borer, Agrilus planipennis Fairmaire, 1888 (Coleoptera: Buprestidae) is described: Agrilus rubensteiniChamorroandJendek,newspecies. This is the first species in the A. cyaneoniger species-group recorded for the Philippines. Agrilus rubensteini resembles A. pseudolubopetri Jendek and Chamorro specifically by the elongate and narrow body shape, the narrow marginal and submarginal pronotal interspace not reaching the anterior pronotal margin, absent prehumerus and arcuate elytral apices, however, it can be easily distinguished from any other species in the group by the presence of golden tomentum in lateral pronotal impressions and laterally on ventrites 3 and 4.
Adult specimens of Geometridae from the Dale H. Habeck Lepidoptera collection were databased in Excel 97 for inclusion in the Florida Museum of Natural History collection databases. A synopsis of data from 58 reared Florida species is presented. Larval hosts are listed from 97 genera representing 45 angiosperm plant families. First known hosts for 11 Geometridae species and previously unknown hosts for 31 species are reported. Records of special interest are discussed including suspected and confirmed cases of lichenivory as well as herbivory of an invasive tree species.
An adventive, previously undescribed species, Neophyllaphis varicolor Miller and Halbert, n. sp., is described and illustrated. A modified key to Neophyllaphis found on Podocarpus spp. (Podocarpaceae) and a key to Neophyllaphis in the USA are provided.
Captive populations can play a significant role in threatened and endangered species management. An important consideration when developing and managing captive populations, however, is the maintenance of genetic diversity to ensure that adequate variation exists to avoid the negative consequences of inbreeding. In this investigation, we compared genetic diversity patterns within captive and wild populations of the federally endangered Quino checkerspot butterfly (Euphydryas editha quino Behr [Lepidoptera: Nymphalidae]), a taxon with a restricted distribution to chaparral and sage shrublands within Riverside and San Diego counties, California. Our analyses revealed that medium to high-frequency alleles from the wild populations were also present in the captive populations. While there was no significant difference in genetic diversity as quantified by expected heterozygosity, the captive populations showed tendencies toward significantly lower allelic richness than their wild counterparts. Given that alleles from the wild populations were occasionally not detected in captive populations, periodic incorporation of new wild specimens into the captive population would help ensure that allelic diversity is maintained to the extent possible. If performed in advance, genetic surveys of wild populations may provide the clearest insights regarding the number of individuals needed in captivity to adequately reflect wild populations.
Dictya behrmaniMurphy,newspecies (Diptera: Sciomyzidae), from Indiana, U.S.A., is described and illustrated. A male collected near Belmont, Brown County, Indiana, U.S.A., represents the only known specimen of the new species. The most recent key to the genus Dictya is updated to include the two species described since publication of the key.
