Remarks

Lohmann (1909) discovered Copidognathus australensis (Lohmann 1909) from southwestern Australia with a very short description. Bartsch (1999) redesrcri-bed this species collected among the seagrass Amphibolis and corals from Rot-tnest Island, southwestern Australia. The Indian specimens match well with the description of Bartsch (1999).

Copidognathus australensis (Lohmann 1909) is allied with C. amaurus Bartsch, 1999, from southwestern Australia (Bartsch 1999), C. bavayi (Troues-sart 1896) from Vietnam, Malaysia (Trouessart 1896, Andre 1937, Bartsch 1993), C. corallorum (Trouessart 1899) from Djibouti and Zanzibar (Touessart 1899, Andre 1938, Chatterjee et al. 2008), C. floridensis Newell, 1947 from Bermuda, Brazil and Florida (Newell 1947, Pepato & Tiago 2005), C. matemwensis Chatterjee, De Troch and Chan from Zanzibar, Tanzania (Chatterjee et al. 2008), C. pere-grines Bartsch, 1977 from the Galapagos Islands (Bartsch 1977), C. pontellus Bartsch, 1981 from Mozambiąue channel (Bartsch 1981), C. rostratellus Bartsch, 1986 from the Philippines (Bartsch, 1986), C. scuna Otto, 1994 from southwestern Australia (Otto, 1994), C. tenuirostris Bartsch, 1977 from the Galapagos Islands (Bartsch 1977), C. tuberipes Bartsch, 1977 from the Galapagos Islands (Bartsch 1977), and C. waltairensis Chatterjee & Annapurna, 2002 from Andhra Pradesh, India (Chatterjee & Annapurna 2002, 2003 ) in having the combination of following characteristics: AD w ith 1 anterior and 2 roundish or oblong middle areolae, in some species two middle areolae fused to form a single median areola; ds, anterior to middle areolae; pair of gland pores located anterolaterally on AD; ds₂ located at anteromedial corner of OC; PD with 2 costae containing rosette pores; ds₃-ds₅ on PD; gland pores situated lateral to costae between ds₄ and ds₅; epimeral process I well developed and coxal in origin; telofemora, genua and tibia with pararthrodial lamellae; basifemora III—IV devoid of ventral lamella, telofemora III—IV with 0 and 1 ventral seta respectively; tibiae I-IV with 2, 2,

1    and 0 pectinate setae respectively; tarsi III and IV each with 4 dorsal setae,

2    basidorsal setae on tarsi III—IV apart from each other. Copidognathus bermu-densis Bartsch & Iliffe, 1985 from Bermuda Island (Bartsch & Iliffe 1985) and C. guttatus Bartsch, 1977 from the Galapagos Islands (Bartsch 1977) have many characteristics in common and can also be related to these species group.
