Abstract:Species diversity of terrestrial earthworm in Langfang region (Hebei province, China) was investigated from June to October, 2014. A total of nine species belonging to six genera, three families were recorded. Three dominant species including Drawida gisti, D. japonica, and Aporrectodea trapezoides were identified. Morphological diversity was analyzed and compared according to the morphological structure indices such as length, width and segment number. The results showed thatthe segmentnumber of D. gisti was ranged from 51 to 207, and the mean length of 55 individuals was 59.80 mm±19.15 mm, the mean width was 4.30 mm±1.21 mm; the segmentnumber of D. japonica was ranged from 54 to 174, and the mean length of 78 individuals was 42.00 mm±10.90 mm, the mean width was 3.00 mm±0.69 mm; the segmentnumber of A. trapezoides was ranged from 67 to 191, and the mean length of 37 individuals was 63.40 mm±20.72 mm, the mean width was 4.50 mm±0.92 mm.Significantly positive correlation was found between the length and width of the dominant species (P<0.05), and between the length and segment number (P<0.01). Additionally, the result of cluster analysis of the individual length was conformed to the law of species-genus difference, but the width of D. gisti was larger than D. japonica and A. trapezoides.
