AbstractInvasive freshwater crayfish are spreading rapidly across the world. Here, we report the first record of Australian redclaw crayfish, Cherax quadricarinatus (von Martens 1868) in Hong Kong, China. Identification of the captured crayfish was confirmed using external morphological features and molecular analyses. A total of 49 crayfish were captured from a stream pool and a reservoir in Pok Fu Lam Country Park using dip nets and funnel traps. The captured C. quadricarinatus ranged from 17.20 mm to 56.40 mm (mean = 30.70) in carapace length and the sex ratio was 1:1. Since this species is globally recognized as an invasive species, a comprehensive survey on its status and invasion front, an investigation into its potential ecological impacts, as well as the formulation of a monitoring and removal strategy, are warranted.

A new suctorian ciliate, Tokophrya huangmeiensis sp. n. was isolated from the carapace of redclaw crayfish Cherax quadricarinatus, during investigation of fish ciliates diversity in freshwater aquaculture of Hubei, China. The zooids of newly isolated ciliate were found aggregated into colonies on stalks of another ciliate Epistylis. The adults of this newly found species were characterized by an elongated pyramidal shaped and corrugated cell body with two fascicles of tentacles on the apical part of cell body. Stalks were hollow and transparent with longitudinal striations. The single contractile vacuole was located in the apical region and an elongated ρ-shaped macronucleus was situated along the long axis of cell body. Phylogenetic analyses showed that the subclass Suctoria is monophyletic and comprises the groups Exogenina, Evaginogenina and Endogenina, where Exogenina is the earliest branching lineage among these three groups. Tokophrya huangmeiensis sp. n. clustered with the other Tokophrya species and within the Endogenina subgroup as expected.

Two new species of the genus Laena Dejean, 1821 (Coleoptera: Tenebrionidae: Lagriinae) are described from Hong Kong: Laena hongkongica sp. n. and Laena walkeri sp. n. These constitute the first record of the genus from Hong Kong, as a species previously described from nearby area Laena ovipennis Schuster, 1926, in fact originated from Zhejiang province nearby Shanghai. Both species from Hong Kong possess a wide variation in body length, which is quite unusual for this genus.
