Chi-Feng Lee, Sadatomo Hisamatsu, and Ping-Shih Yang (2007) Three larval instars and the pupae of Helota thoracica
Ritsema, 1895 are described and figured for the first time. The larval
chaetotaxy of the head, pro- and mesonota, abdominal terga III, legs,
abdominal sterna III, and urogomphi is described. Almost all setae
present in larval instar I are primary. Subprimary setae appear on the
abdominal sternites, head, and legs. Pupae are very conservative since
no differences were observed between H. thoracica and H. gemmata. A novel method for rearing adult and larval helotids is also provided.
Key words: Taxonomy, Larval chaetotaxy.
