ITE— India (Andaman & Nicobar Islands). Reamrks. Copidognathus eblingi belong to a natural group which contains species: C. punctatissimus (Gimbel, 1919) from eastern United States (Gimbel 1919; Newell 1947), C. dentatus Viets, 1940 from northeastern Atlantic, Mediterranean Sea (Viets 1940; Durucan 2019), C. dentipes Bartsch, 1989 from Hawaiian Islands (Bartsch 1989), C. eblingi from Andaman Islands, India (Bay of Bengal) (Chatterjee 1991a; Chatterjee & Annapurna 2003), Copidognathus jejuensis Chatterjee & Chang, 2004 from South Korea (Chatterjee & Chang 2004, 2006), Copidognathus mumbaiensis Chatterjee & Chang, 2004 from Mumbai, India (Chatterjee & Chang 2004), Copidognathus pesident Bartsch, 1992 from Society Island (Bartsch 1992), Copidognathus tupinamborum Pepato & Tiago, 2005 from Brazil (Pepato & Tiago 2005). Some of these very closely related species share very similar morphological characters, and require detailed study and molecular sequence for being validated.Published as part of Chatterjee, Tapas, 2022, An annotated checklist of halacarid mites (Acari, Halacaridae) from India, pp. 301-320 in Zootaxa 5141 (4) on page 305, DOI: 10.11646/zootaxa.5141.4.1, http://zenodo.org/record/659286

    Copidognathus balakrishnani Chatterjee, 2000 Records from India. GOA: Chorao Island, North Goa, among algal turf growing on Avicennia mangrove pneumatophores — Chatterjee (2015b). KERALA: Cochin backwater, among Enteromorpha sp. —Chatterjee (2000); Vembanad lake, upstream— Dev Roy et al. (2009). Distribution. ITE— India (Goa). Remarks. Scanning electron microscopic observations of this species from Goa (west coast of India) was given in Chatterjee (2015b). This species belongs to ‘ C. balakrishnani group’ (Chatterjee et al. 2012b, Chatterjee 2015b). This group is characterized by short rostrum, small palps; areolae and costae with porose panel; PD with 4 costae; pectinate setae on tibiae I–IV: 2-2-1-1; tarsi III–IV with lateral PAS, medial PAS absent, setae ds 2 on OC, setae ds 3 -ds 5 on PD. Four species viz. Copidognathus balakrishnani Chatterjee, 2000 from India (Chatterjee 2000, 2015b), C. caloglossae Procheş, 2002 reported associated with the algal complex, ‘ Bostrychietum ’, covering the pneumatophores of mangrove Avicennia marina at Richards Bay, Isipingo and Beachwood mangrove forests in KwaZulu-Natal, South Africa, and at Inhambane, Mozambique (Procheş et al. 2001; Procheş 2002; Procheş & Marshall 2002), C. lutarius Bartsch, 2003 reported among the turf of mangrove A. marina on the east coast of the Burrup Peninsula, Dampier, Western Australia (Bartsch 2003a) and C. rhombognathoideus Bartsch, 2006 reported from algae on sediments, as well as pneumatophores and stems of mangroves in Singapore (Bartsch 2006) and from algal turf growing on Rhizophora mangrove pneumatophores at Batu Marang, Brunei Darussalam (Chatterjee et al. 2012b) was assigned to this natural group (Chatterjee 2015b). All these species were reported from low salinity zones associated with mangroves and algae (Chatterjee 2015b).Published as part of Chatterjee, Tapas, 2022, An annotated checklist of halacarid mites (Acari, Halacaridae) from India, pp. 301-320 in Zootaxa 5141 (4) on pages 304-305, DOI: 10.11646/zootaxa.5141.4.1, http://zenodo.org/record/659286

    Copidognathus gitae Chatterjee, 1991 Records from India. ANDHRA PRADESH: Visakhapatnam, Palm beach, among tidal green algae Caulerpa racemosa and Caulerpa taxifolia — Chatterjee (1991b), Chatterjee & Annapurna (2003). Distribution. ITE— India (Andhra Pradesh). Remarks. This species is a member of ‘ Copidognathus spinula group’ (a subdivision of Copidognathus bairdi group) (Bartsch 1997).
