The fl at bugs (Hemiptera: Aradidae) are primarily mycophagous, and some species may pose a threat to cultivated mushrooms. In addition, at least one species feeds on living plant tissue. For this reason, they are potentially of economic signifi cance. Their identifi cation below family level is sometimes diffi cult, partly due to the scattered nature of the literature. We present a list of the aradids intercepted at United States Ports of Entry from 1992 to March 2013. In addition, we provide keys and diagnoses for the identifi cation of aradid subfamilies and the intercepted, reportable genera of the Aradidae.

We present a list of the species of the genus Thrips (Thysanoptera: Thripidae) of quarantine importance to the United States and which have been intercepted in cut flowers (multiple species) imported from Europe. A total of 14 species of quarantine importance were recorded. We provide taxonomic keys for the identification of most of the species along with photographs and diagnostic characters for these species.

The agave snout weevil (AGW) or sisal weevil, Scyphophorus acu- punctatus Gyllenhal is here reported for the first time in St. Croix, U.S. Virgin Islands (USVI) where it threatens Agave eggersiana Trel., a USVI endemic and endangered century-plant. We provide molecular, morphological, and behavioral characters to suc- cessfully distinguish the two known Scyphophorus species at all developmental stages. We identified seven new larval characters on themandibles and characters relating to the chaetotaxy of the labrum and labio-maxillary complex as well as new, putatively infor- mative characters for weevil systematics: chitinized arm of mentum (postlabial strut or postlabial bracon) and the presence of 4 ventral malar setae, instead of 5. In the pupae, the difference in number and placement of rostral setaewere also found to be diagnostic. We analyzed two genes, mtCO1 and EF1a, to confirm the identity of the immatures. Phylogenetic analysis of both genes separately and together suggests a clear pattern of substantial phylogeographic structure with specimens clustering by geographic location and this pattern strongly suggests the presence of cryptic species or allopatrically di- verged populations. We provide management recommendations for the protection of Agave eggersiana against the threat posed byASW.We also report, for the first time, the presence of Sphenophorus cubensis (Buchanan) in St. Croix and Scyphophorus yuccae Horn in Panama on Hesperoyucca whipplei (Torr.) Trel. (Asparagaceae: Agavoideae).

Ackbaria vermiformis gen. & sp. nov. (Deltocephalinae: Faltalini) is described from Chile (Bío Bío and Araucanía Regions) and Argentina (La Pampa and Entre Ríos Provinces). It is differentiated from other Faltalini by the following combination of characters: narrow and dorsoventrally compressed body, brachypterous, forewing without reticulate venation, male pygofer with ventroapical tooth and side with 10–15 macrosetae dorsoapically, and female pygofer with many macrosetae.

New distribution and host records are provided for four whitefl ies intercepted at U.S. ports of entry on propagative material of Magnolia from Asia. Aleuroclava latus (Takahashi, 1934), Aleuroclava nitidus (Singh, 1932), and Cockerelliella meghalayensis Sundararaj & David, 1992 were intercepted on the leaves of Magnolia spp. (Magnoliaceae) from Thailand. Cockerelliella indica Sundararaj & David, 1932 was intercepted on the leaves of Magnolia yunnanensis (Hu) Nooteboom from China. An identifi cation key to the puparia of the whitefl ies found on Magnolia species is included along with revised descriptions and illustrations of all the species based on the specimens intercepted at U.S. ports of entry.

Wedescribe twonewspecies of bees fromColombia;one is a species of Exomalopsis found nesting in the city ofMedellin,Colombia, (the host) and its cleptoparasitic bee, a species of the genus Nomada. In addition, we provide information on the nest architecture of the new species and provide data on occupancy by both the host bee and its cleptoparasite. We present an updated list of the species of Exomalopsis and Nomada of Colombia and taxonomic keys to the species of Exomalopsis.
