Six new species of Agrilus Curtis, 1825 with affinities to the emerald ash borer, Agrilus planipennis Fairmaire, 1888, are described from the Oriental Region: Agrilus crepuscularis sp. n. (Malaysia); Agrilus pseudolubopetri sp. n. (Laos); Agrilus sapphirinus sp. n.(Laos); Agrilus seramensis sp. n.(Indonesia); Agrilus spineus sp. n. (Malaysia); and Agrilus tomentipennis sp. n. (Laos). The genus Sarawakita Obenberger, 1924 syn. nov. is considered a junior synonym of Agrilus.

The current study stems from an international, multi-agency effort between the following institutions (listed in alphabetical order): the Canadian Food Inspection Agency, the Chinese Academy of Sciences Institute of Zoology, the United States Department of Agriculture, and the Zoological Institute, Russian Academy of Sciences to understand the evolutionary relationships and biology of the highly invasive Agrilus planipennis Fairmaire, 1888 (emerald ash borer – EAB) and its relatives. This effort aims to determine, define, and illustrate the characters that enable identification of EAB and a core group of related species; make predictions about potential new invasive species with similar evolutionary histories and adaptations; educate the public and other scientists; and contribute knowledge needed to develop control strategies to manage outbreaks. A comprehensive, illustrated identification manual presenting these findings is underway. In this paper we describe six new species related to Agrilus planipennis and propose new taxonomic and nomenclatural acts discovered during the course of our study.
Materials and methodsTerminology, morphology, format and style of descriptions follow Jendek and Grebennikov (2011). Square brackets “[ ]” are used for our remarks and addenda. The following equipment was used for observation and imaging: Leica (Wetzlar, Germany) MZ Apo stereomicroscope and Zeiss (Oberkochen, Germany) Discovery v20 stereomicroscope with AxioCam HRc, respectively.

Upon examination of the material mentioned above and the type specimens of Agrilus hewitti, Sarawakita latifrons and Agrilus daillieri we have come to the conclusion that Sarawakita should be treated as a junior synonym of Agrilus.
Agrilus daillieri and Agrilus hewitti are very closely related, large (> 10 mm) and robust species which share many morphological features with Agrilus planipennis. Their taxonomic position will be analyzed in detail in the upcoming revision.

Figs 24–39The male resembles Agrilus lubopetri Jendek, 2000 in color, shape and size; however, the following characters distinguish the males of the two species: Agrilus pseudolubopetri sp. n. does not have expanded elytral apices and lacks white pubescence; the interspace between marginal and submarginal pronotal carinae is broader anteriorly in Agrilus pseudolubopetri; and the aedeagus is broader subapically. Female can be distinguished from females of Agrilus lubopetri by larger, more robust size, purple color (sometimes green to copper), and by unexpanded elytral apices.

http://species-id.net/wiki/Agrilus_tomentipennis
Figs 72–80Agrilus tomentipennis from Laos is very similar to Agrilus planipennis. Both species have a small scutellum; identical marginal and submarginal carinae; a pygidial spine; and highly sinuate posterior margin of the metatibiae. While many of the differences between these two species may be considered mostly continuous, such as larger size (Agrilus tomentipennis), larger and more pronounced prehumeral carina (Agrilus tomentipennis); and deeper frontal concavity (Agrilus tomentipennis), two additional features set Agrilus tomentipennis apart from Agrilus planipennis: the presence of a row of perisutural stripes of white elytral pubescence with indication of a preapical tomentose spot, and a more rectangular scutellum in Agrilus tomentipennis (diamond-shaped in Agrilus planipennis).

The specific epithet is a combination of Latin nouns tomentum (woolly hairs) and pennae (elytra). The name alludes to the presence of white pubescence on the elytra.
Jendek and Grebennikov (2011) cited specimens of this taxon in examined material as Agrilus planipennis.
