Synetocephalus penrosei sp. nov. from Monterey County, California, U.S.A., is described and illustrated. Comparisons are made with the two most similar species, S. bivittatus (LeConte 1859) and S. diegensis (Blake 1942). Adults of S. penrosei are associated with Adenostoma fasciculatum Hook & Arn. (Rosaceae) during the spring months when plants are in bloom.

We determined the distribution of Rhagoletis fausta (Osten Sacken 1877) and Rhagoletis indifferens Curren 1932 (Diptera: Tephritidae) in California outside the state interior quarantine area. Our data confirmed the historical records of R. fausta in Alpine, Amador, El Dorado, Fresno, Kern, Mariposa, Mendocino, Modoc, Mono, Nevada, Placer, Plumas, Sierra, Tehama, Tulare, and Tuolumne counties and we trapped R. fausta for the first time in Butte, Calavaras, Glenn, Inyo, Lassen, Madera, and Yuba counties. We confirmed the historical records of R. indifferens in Amador, El Dorado, Fresno, Mendocino, Modoc, Nevada, Placer, Plumas, and Sierra counties and we trapped R. indifferens for the first time in Butte, Calaveras, Lassen, Madera, Mariposa, Tulare, Tuolumne, and Yuba counties. No R. fausta were trapped in Lake, Los Angeles, or San Bernardino counties and no R. indifferens were trapped in Alpine, Glenn, Inyo, Lake, Mono, or Tehama counties. The lower altitude at which we trapped both flies increased significantly southward from the northern end of the flies' range in California. The large, host free distances between the populations of R. fausta and R. indifferens and the major commercial sweet cherry production areas in California and the asynchrony between the time when commercial sweet cherry fruit are available for attack and the presence of adults of both fly species effectively prevent the adult flies from naturally dispersing into the major commercial sweet cherry production areas of the state and establishing breeding populations.

Hybopteroides gen. nov., with three new species in the Cryptobatida group of subtribe Agrina, Lebiini, living in the lowland rain forest canopy of Ecuador and Perú are diagnosed, described and illustrated. The new genus is likely the adelphotaxon of Hyboptera Chaudoir 1872 Thoasia Liebke 1939. Hybopteroides biolat sp. nov., the type species, is now known from the Río Manu watershed in Perú; Hybopteroides karolynae sp. nov. is now known from the Río Tambopata watershed in Perú; and Hybopteroides penrosei sp. nov. is now known from the upper and mid Río Napo watershed in Ecuador. The species of this new genus are known from insecticidal fogging collections from the rainforest canopy and upper understory and from two specimens collected by E. S. Ross at his ecotourism lodge at Alinahui, Ecuador, found in his live embiid colonies.

A new sap beetle species, Lobiopa penrosei Cline & Kinnee sp. nov., is described from Baja California Sur, Mexico. Habitus and genitalia images are provided. Major characters distinguishing L. penrosei include: dorsal surface setation consisting of all light colored thin and spatulate/subclavate setae with no dark to piceous setae present; spatulate/subclavate setae straight/erect not curved; and internal sac sclerites of male genitalia with a paired basal field of spines as well as ejaculatory rods with constricted bases. A review of Lobiopa Erichson is given, including biological notes on some of the inclusive members as well as a checklist of all described species.

A new species of Ammoplanus, A. natei, a new species of Parammoplanus, P. penrosei, and the unknown female of P. lenape (Pate 1937) are described. Partially revised keys are provided for Ammoplanus Giraud 1869 and Parammoplanus Pate 1939. Ammoplanops irwini R. Bohart & N. J. Smith 1978 is transferred to Pulverro. Pulverro eighmei N. J. Smith 1983 is entered into synonymy as P. irwini.

A spermophagous bark beetle (Coleoptera: Curculionidae: Scolytinae), Dactylotrypes longicollis (Wollaston), indigenous to the Canary Islands and Madeira, is documented from North America for the first time other than via occasional interceptions in imported palm seeds. Specimens were initially found in Lindgren funnel traps at two arboreta in southern California in 2009. Dead specimens were subsequently found in the fallen seeds of Brazilian needle palm, Trithrinax brasiliensis Martius (Arecaceae), at one of the arboreta. This palm is a new host record for this beetle previously known from several other genera of palms and Dracaena draco (Linnaeus) (Ruscaceae). Based upon the distribution of known and potential hosts, D. longicollis will probably be restricted to the vicinity of the southern border of the United States in North America and possibly greenhouses. As it only attacks the seeds of palms and related plants, it is unlikely to become a pest in North America. Since specimens were found in traps at two localities and from seeds at one site, we believe D. longicollis is established in North America.

The diurnal flight response of the walnut twig beetle, Pityophthorus juglandis Blackman (Coleoptera: Scolytidae), was assessed during two seasonal periods at two sites in northern California. Males and females flew primarily at dusk in response to aggregation pheromone-baited traps during late June/early July, and the percentage of beetles that flew between sunrise and late afternoon was positively correlated with the temperature at 6 AM of that day. Between late August and early November, the diurnal flight pattern was more varied and generally bimodal, though approx. 42 to 55% of the beetles still flew during the dusk period. During either period of the season, there was very little evidence that any flight occurred during the night. Between late August and late September, diurnal flight of both sexes during two-hour intervals was associated with temperature in a Gaussian manner with a threshold at 17–18 °C (62.6–64.4 °F) and peak activity at 23–24 °C (73.4–75.2 °F). The proportion of females in the catches of P. juglandis that responded to pheromone-baited traps ranged from 0.43 to 0.84 but did not vary throughout the day within a seasonal period.

By measuring and analyzing larval head capsule widths, we determined that a northern California population of the walnut twig beetle, Pityophthorus juglandis Blackman (Coleoptera: Scolytidae), has three larval instars. We also developed rules to classify P. juglandis larval instars. Overlap in the ranges of widths among consecutive instars was addressed by fitting a distribution model to the data and determining limits for head capsule width classes and probabilities of instar misclassification. Growth ratios for laboratory and field samples of P. juglandis were consistent with the Brooks-Dyar rule and with results in the literature for other bark and ambrosia beetle species. As a consequence of branch dissection to retrieve larvae of P. juglandis, we established that northern California black walnut, Juglans hindsii (Jeps.) Jeps. ex R.E. Sm., is a host for the xylophagous “California hardwood bark beetle,” Hylocurus hirtellus (LeConte) (Coleoptera: Scolytidae), and that H. hirtellus is associated with P. juglandis beneath the bark of small diameter branches. It appears that in northern California, univoltine H. hirtellus is active in flight from early March through early May, with the majority of the adults dispersing in April. The females are the colonizing sex.

A new monotypic genus of Madagascan Coraebini, Penroseius, is proposed for a new species, Penroseius lienosus in memory of Richard L. Penrose. The new genus is compared to other putative relatives from the Madagascan fauna and illustrated in five figures on one plate.
