Distribution. 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).

C. bermudensis Bartsch & Iliffe, 1985 and C. guttatus Bartsch, 1977 have many characteristics in common and can also be related to the present species. C. asperatus Newell, 1984, C. lamellosus (Lohmann, 1893), C. simonis (Lohmann, 1907) and C. transversus Newell, 1984 (Lohmann 1893, 1907a, b; Newell 1984; Bartsch 2000) lack some information on gland pores, details of leg-morphology etc but also have some similarities to the present species. Of these species C. matemwensis sp. nov. resembles C. asperatus, C. australensis, C. bavayi, C. bermudensis, C. floridensis, C. lamellosus, C. peregrinus, C. scuna, and C. tuberipes due to the presence of the two median porose areolae on AD but differs from them in having areolae containing rosette pores on the lateral side of anterior half of GA which tend to join with areolae laterally to GO area, while areolae are present lateral to GO area only in other species (Table 1). Additionally, a pair of ventromedial areolae are present between lateral and posterior setae of AE in C. matemwensis sp. nov but are absent in others (Table 1). Further comparison of characteristics between C. matemwensis sp. nov. and its related 9 species are given in Table 1.

Copidognathus corallicolus Chatterjee, De Troch & Chang, 2006 was reported from Zanzibar (Chatterjee et al. 2006) and differs from C. matemwensis in having ds 2 on membranous cuticle between AD and OC, costae on PD single rosette pore wide, tibia IV with 1 pectinate ventral seta, tarsus IV with 3 dorsal setae. Etymology. The specific epithet matemwensis alludes to the type locality of this new species, Matemwe (Zanzibar, Tanzania).Published as part of Chatterjee, Tapas, Troch, Marleen De & Chan, Benny K.
