AbstractWe describe three new species of fruit flies (Tephritidae: Tephritinae) (Gymnocarena defoeisp. nov. and Gymnocarenanorrbomisp. nov., from eastern North America and Gymnocarena monzonisp. nov. from Guatemala) and redescribe Gymnocarena mississippiensis Norrbom. Gymnocarena monzoni is the first Gymnocarena species to be recorded from Guatemala. This brings the total number of named species in this genus to 19. New larval host plant (Asteraceae) records for Gymnocarena include Verbesina helianthoides Michx. for G. mississippiensis and G. norrbomi, Verbesinaalternifolia (L.) Britton ex Kearney for G. norrbomi, and Viguiera cordata (Hook. and Arn.) D'Arcy for G. monzoni. The latter represents the first record for Gymnocarena in Viguiera Kunth. Gymnocarena larvae were also recorded from Verbesina virginica L. but not identified to species. A revised key to the known species of Gymnocarena and additional information on larval host plants and biology are provided.

Phenotypic Convergence

Through integrating molecular, morphological and natural history evidence, nominal Hemaris diffinis (Boisduval) of eastern North America is shown to include a second, cryptic species, Hemaris aethra (Strecker) stat. rev. Despite highly divergent mtDNA sequences and differing larval phenotypes, genitalic morphology, habitat and larval host plants, adults of H. aethra and sympatric H. diffinis are externally so similar that H. aethra has remained unrecognized for over a century. With a more northerly distribution than H. diffinis, H. aethra occurs from Manitoba to Nova Scotia and adjacent parts of the United States, the two species occurring in strict sympatry in eastern Ontario and likely other regions. Co-mimicry of Bombus Latreille bumblebee models has likely resulted in phenotypic convergence of H. diffinis and H. aethra, as the two do not appear to be sister taxa, the latter instead being more closely related to the western species H. thetis (Boisduval). The larvae of H. aethra are illustrated for the first time, together with diagnostic images and comparisons of adults. Lectotypes are designated for Hemaris tenuis Grote and Hemaris marginalis Grote.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]

Work Done

Although the interest in shell middens in North America is often traced to reports of the discoveries in Danish kjoekkenmoeddings in the mid-nineteenth century, extensive shell midden studies were already occurring on the East Coast by that time. This article reviews selected examples of this early work done by geologists and naturalists, which served as a foundation for shell midden studies by archaeologists after the Civil War.
