  • Cawjeekelia iksana sp. n. is described from South Korea. The family Haplodesmidae, the genus Rhipidopeltis Miyosi, the species Rhipidopeltis sinuata Miyosi, and Hyleoglomeris emarginata Golovatch are recorded in Korea for the first time. The genus Megalotyla Golovatch as well as the species Cawjeekelia pyongana Mikhaljova and Kim, Tokyosoma ronkayi (Shear) and Yamasinaium koreanum Golovatch, are new to the fauna of South Korea.

  • The antennae of millipedes have a prominent function in detecting various types of environmental stimuli. The structural modification of the antennae is closely associated with the degree of sense recognition. Here we study functional morphology of the antennae of the millipede Cawjeekelia pyongana using field emission scanning electron microscope (FESEM). The antennae generally include eight segments, called articles. On the surface of the antennae, there are a variety of sensory receptors which include olfactory and mechanical receptors. We could identify four different types of antennal sensory organs in C. pyongana as follows: apical cone (Ac), trichoid sensilla (Ts), chaetiform sensilla (Cs) and basiconic sensilla (Bs). The most prominent of which is four APs at the 8th article. Both of the Is and the Cs are abundantly observed almost all of the antennal segments. They are long and strong bristles with longitudinal grooves acuminating toward the tip. The Bs is further divided into three subtypes: large basiconic sensilla $(Bs_1)$, small basiconic sensilla $(Bs_2)$ and spiniform basiconic sensilla $(Bs_3)$. The $Bs_1$ is located at the 5th and 6th articles, while the $Bs_2$ and $Bs_3$ can be seen at the 5th and at the 7th article, respectively.
