ABSTRACT The Asian chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu is an invasive species of global concern that was inadvertently introduced into North America where it induces gall formation on chestnut species including Castanea mollissima Blume, C. crenata Siebold & Zucc., and C. sativa Mill. as well as on the American chestnut, C. dentata (Marshall) Borkh. The gall former was introduced into the United States in the 1970's and since its initial introduction into Georgia, it has been reported to have spread to 13 other states. It has previously been documented as far to the northeast as Connecticut and Massachusetts and as far to the northwest as Michigan. Prior to this study it had been reported in 13 counties within the state of Pennsylvania. The introduction and spread of D. kuriphilus is of particular concern given the intensive efforts to restore American chestnuts into the North American landscape. The purpose of this study was to gain a better understanding of the distribution and spread of the Asian chestnut gall wasp in Eastern Pennsylvania and neighboring states. During the course of this study, specimens of Castanea spp. (Fagaceae) were assessed/monitored for the presence of galls caused by D. kuriphilus at over 100 sites in four states. Herein, galls caused by the Asian chestnut gall wasp are documented, for the first time, on Castanea spp. at several sites in the U.S. states of New Jersey, New York, and Delaware, new state records. Additionally, we report an expansion of the range of the Asian chestnut gall wasp to encompass twenty additional counties within Eastern Pennsylvania. Dispersal of the gall wasps in this study appears to have been influenced by topographical features and wind direction. For further confirmation of identity, we reared D. kuriphilus from galls collected at several sites. These findings establish the range expansion of this gall-forming invasive pest species in the United States to now encompass all of the Mid-Atlantic States.

ABSTRACT Morphologies of male genitalia of Elateridae (Insecta: Coleoptera) were examined comprehensively by using scanning electron microscopy (SEM). Aedeagal ultrastructures of 65 species were investigated in detail. New morphological structures including small pustules on the apical part of median lobe, small pits with short spine on median lobe and parameres and spines and teeth of inner sac of median lobe were observed for the first time. The long and short bristles of male genitalia were examined comprehensively. Systematic value of these structures are evaluated within examined genera and subfamilies by using a cluster analysis. These morphological structures are heterogeneous within the subfamilies. Consequently, results of cluster analysis exhibit that the observed structures can not be accepted as taxonomical characters for differentiating subfamilies with the exception of the diagnosis of some genera.

ABSTRACT An annotated list of the Meloidae family in Turkey and a zoogeographical study is presented. The Turkish fauna consists of two subfamilies, 23 genera, and 177 species. The Eastern Anatolia region was found to be the most diverse with 98 species. The fauna of the Aegean and Marmara regions of Turkey share the most similarities compared to other regions. Overall, the Turkish Meloidae fauna is more similar to that of Syria than to that of other adjacent countries. As a result of the evaluations, it is evident that Cerocoma dahli Kraatz, 1863, C. kunzei Frivaldszky von Frivald, 1835, C. scovitzi intermedia Mařan, 1944, C. ephesica Reitter, 1885, Hycleus zebraeus Marseul, 1870, Mylabris calida Pallas, 1782, M. fabricii Sumakov, 1924, M. quadripunctata Linnaeus, 1767, and Stenodera caucasica Pallas, 1781 are distributed throughout Turkey, and Euzonitis sexmaculata Olivier, 1789 is present both in Turkey and all adjacent countries.

ABSTRACT Pseudothilmanus Pic, 1918 is a genus of beetles currently placed in Rhagophthalmidae. The species P. alatus Pic, 1918 and P. marginatus Pic, 1918 were described based on single holotypes from India with little descriptive information. Later, in a revision of the genus, a new specimen of P. alatus was examined, but also without specific locality. This paper provides the description of the wing venation and new distributional records for this genus, including the first record in Nepal.

ABSTRACT Camponotus planatus Roger (Hymenoptera: Formicidae) is a broadly distributed New World carpenter ant. Here, I document the geographic distribution of C. planatus and consider evidence concerning where this species may be native, particularly whether it is native to Florida. To evaluate the distribution of C. planatus, I compiled and mapped specimen records from >1500 sites. Although, C. planatus was originally described from Cuba, it remains uncertain whether it is native or exotic there. In addition to scattered records across tropical South America, C. planatus shows a largely continuous continental distribution from Panama through Central America and Mexico to southeastern Texas. Across this continental range, C. planatus shows notable color variation, suggesting that it is native to this region. In Texas, C. planatus records dating to before 1980 are spread across most of its known range. However, eight of the nine northernmost records date to 2014 or later, including all six records from the Houston area in East Texas. This pattern suggests that C. planatus is native to Texas, but populations there appear to have recently expanded, perhaps due to climate change. Camponotus planatus populations in Florida, the Bahamas, and Mississippi are probably non-native. In Florida, C. planatus was first found in Key West in 1887, but populations appear to have greatly expanded, particularly since 1980, and now extend as far north as Jacksonville. Due to continued climate change, C. planatus may soon be able to extend its range all along the Gulf coast from Texas to Florida.

ABSTRACT At present, most species of Hercostomus were divided into 25 species groups in China. In this paper, we proposed a new species group, the Hercostomus furcatus group, on the basis of the black body and legs, the yellow middle and lower postocular bristles, and the furcated cercus with distinct marginal denticles. Here one new species, Hercostomus liangi sp. n., from China and it is described as new to science. A key to species groups of Hercostomus is provided.
