The aphid genus, Takecallis Mastumura, 1917, was reviewed from Korea. Four species, T. alba Y. Lee, sp. n., T. arundicolens (Clarke), T. arundinariae (Essig), and T. taiwana (Takahashi), are recognized in Korea and morphological and molecular evidence are presented. Species descriptions and illustrations are given for the four species. A key to Korean species and the results of COI sequence analyses are also provided.

The genus Takecallis was established by
In Korea, three species, Takecallis arundicolens, T. arundinariae, and T. taiwana, have so far been recorded in this genus (
A total of four species were recognized in Korea. Both morphological and molecular evidence strongly indicated that T. alba Y. Lee, sp. n. is a valid species. Here, together with a description of the new species, photographs of live aphids and illustrations are provided along with a key to species of the genus Takecallis in Korea. Pairwise distance analyses and a neighbor-joining tree based on the partial COI sequence are also provided.
Aphid samples were collected in South Korea from 1999 to 2015. All samples were preserved in 90–95% ethanol for over one month, and then mounted in Canada balsam, following the methods of
Aphid samples were identified using keys to Takecallis species by

In total, 63 COI sequences of five Takecallis species were downloaded from GenBank (Suppl. material
Takecallis Matsumura, 1917: 354, 373.
Takecallis bambusae Matsumura, 1917 (= T. arundicolens) by original designation.
Alatae: Morphological features of Takecallis are similar to Subtakecallis Raychaudhuri and Pal in having a nose-like processus on the clypeus, and spinal abdominal setae surrounded by cribriform wax glands. However, this genus can be distinguished from the above genus by the following characters: PT/BASE ≥ 1.00 and spinal abdominal setae often at low elevations. Apterae are unknown.
Takecallis species occur on various bamboos such as Arundinaria spp., Bambusa spp., Dendrocalamus spp., Pseudosasa spp., Phyllostachys spp., Pleioblastus spp., and Sasa spp. (Poaceae).
This genus is native to the Oriental region, but one or more species occur as introduced populations in Australian, Ethiopian, Palearctic, Nearctic, and Neotropical regions.

Among the examined specimens, it is described that four alate viviparous females were collected on Gramineae sp. However, this host plant is probably not a true host plant due to Takecallis species being recorded only on bamboo species, and is probably a misidentification.

The NJ tree of partial COI sequences suggested that 63 sequences are distinctly divided into six groups (Fig.
Except for the T. arundicolens complex, the rest of the four species showed 0 % of intraspecific genetic divergence (Table

Molecular evidence strongly indicates the validity of T. alba sp. n. All of the individuals of T. alba sp. n. were grouped together and this group was clearly separated from other species groups with a high interspecific distance level that ranged from 9.36 % to 13.46 % (Table
In the present study, four Takecallis species were recognized from Korea. Our study demonstrated that the four species are clearly separated based on morphological and molecular evidence. However, the taxonomic status of genetically distinct groups within the T. arundicolens complex still needs to be resolved.
