Genus Hircella Mayer, 1882 View in CoL
Diagnosis
Head fused with pereonite 1. Antenna 1 well developed, flagellum with more than two articles; accessory flagellum absent. Antenna 2 well developed; flagellum with two or three articles. Mandible well developed; molar absent; palp 3-articulate; palp setal formula 0 – x – 1. Maxilliped well developed; inner plate (basal endite) larger than outer plate (ischial endite); palp article 3 without distal projection; palp article 4 well developed. Pereonite 4 clavate appendage absent. Pereonites 6 and 7 not fused. Pereopod 3 absent. Pereopod 4 absent. Pereopod 5 present with one article. Pereopods 6 and 7 well developed, with seven articles. Gills on pereonites 2 to 4. Pleopods absent. Uropods 2 pairs; uropod 1, uniramous; uropod 2, uniramous. Telson (dorsal lobe) present.
Type species
Caprella cornigera Haswell, 1879b View in CoL , monotypy.
Included species
Hircella View in CoL includes three species: Hircella berentsae Guerra-García, 2006 View in CoL ; Hircella cornigera ( Haswell, 1879b) View in CoL ; Hircella inermis Guerra-García and Takeuchi, 2004 View in CoL .
Remarks
The genus Hircella was established specifically for H. cornigera ( Haswell, 1879b) by Mayer (1903). Recently, Guerra-García and Takeuchi (2004) described the second species of Hircella , H. inermis Guerra-García and Takeuchi, 2004 from the Tasmanian coast. Mayer (1903) mentioned that pereopod 5 of Hircella was completely degenerate, and the diagnosis of Takeuchi (1993) followed his conclusion. Since the type specimen deposited in the Australian Museum is lost ( Springthorpe and Lowry 1994), this new diagnosis is based on recently collected specimens from the Solitary Islands, New South Wales. Observation revealed that pereopod 5 is composed of one tiny article and the number of articles in the flagellum of antenna 2 increases from two to three during growth (see Figure 10 View Figure 10 ). Hence, the generic diagnosis of the present genus is revised as above.
