The life-cycle and seasonal abundance of Anaulaciulus koreanus koreanus was studied at Hwang-dong, Chonbuk Province, Korea from October 1990 to February 1992. The egg hatches in spring and the pupoid stage is passed through within the egg shell. The juvenile develops as far as stadium IX by the third year following the birth. Pairing and oviposition take place in the fourth year spring when females are at stadium XI. They seem to live one or two years more after egg-laying. Anamorphosis was observed in this species. Abundance of A. koreanus koreSanus increases from April to May when there appears thefirst peak. It fals gradualy thereafter and the species spends summer months underground from July to September. The second peak appears in October and the activity decreases again in November getting ready to overwinter. The first peak arises from a large number of individuals of 2 and 3 year old overwintered plus newly hatched spring juveniles, and the second from 1 to 3 years old wanderings. Inactivity observed in the species during summer and winter seasons appears to be a temporal due to the extreme temperatures.

The antennae of millipedes have a prominent function in detecting various types of environmental stimuli, and structural modification of the antennae is closely associated with the degree of sense recognition. Although the biological significance of the antennal sensillae to millipedes are widely understood, the structure and function of the antennal sensillae are still not clear and more precise analysis is required. We have analysed the ultrastructural characteristics of the antennal sensillae in a millipede Anaulaciulus koreanus koreanus using field emission scanning electron microscopy (FESEM). According to their morphological and substructural features, we could identify three different types of antennal sensillae as follows: trichoid sensilla (TS), chaetiform sensilla (CS) and basiconic sensilla (BS). The TS on the articles are long, blunt-tipped, almost straight hairs with deep longitudinal grooves in their lower parts whereas, the CS are long, sickleshaped bristles with longitudinal grooves acuminating toward the tip. The BS can be subdivided further into three subtypes which are the large-sized basiconic sensilla ($BS_1$), the small-sized basiconic sensillae ($BS_2$) and the spiniform basiconic sensillae ($BS_3$). The BS between the terminal segment and distal margins of the other segments are clearly discriminated in this species.

This systematic study of the Myriapoda was based on the materials collected through the Tullgren instrument from Mt. Mudeung in South Korea. As a result, two species of Symphyla, Hanseniella orientalis Hansen and Symphylla vulgaris Hansen are recorded in Korean fauna for the first time. Four species plus 3 unidntified from seven fenera Diplopoda (Hyleoglomeris koreanus Golovatch, Anaulaciulus koreanus koreanus Verhoeff, Brachycybe nodulosum Verhoeff. Diplomaragna gracilipes Verhoeff) and five species (1 unnamed species) in four genus of Chilopoda ( Prolannonyx holstii Pocock. Scolioplanes maritimus japonicus Takakuwa, Scolopocryptops rubiginosus Koch, Lithobius koreanus Verhoeff) were recognized.
