In the present study, early morphological development of Erromyzon kalotaenia, a species of the Gastromyzontidae distributed in Guangxi, China, through the pre-incubation embryos to the juvenile stage was investigated. The eggs of E. kalotaenia were adhesive and demersal with egg membrane diameter 2.03 ± 0.04 mm. The yolk was white. At 24 °C, the embryo developed into a larva outside of the membrane at 45 hrs 28 min. The newly hatched larvae were 4.90 ± 0.14 mm in TL with 37 pairs of myomere. At the 30th day post-hatching, developments of fins were completed and then the juvenile stage was entered.
