Copidognathus quadricostatus (Trouessart, 1894) ( Figs. 11 A–J )

Material examined Bilem Beach, 5 m, fine sand, 4 ♀♀, 2 ♂♂.

Morphology and notes Females 270–275 long, 140–150 wide, that of males 300 long, 170 wide. Major parts of AD, OC, and PD reticulate and, meshes of reticulum undivided. AD 50 long, 65 wide; anteriorly truncated. OC 75 long, 23 wide; slender with three corneae and longer than AD. PD 210 long, 100 wide; two costae and extending anterial beyond anterior margin of OC. AE with three pairs of ventral setae and “U” shaped porose areola. Female AE 112 long, 137 wide. Epimeral pores 7–9 wide. PE with 1 dorsal and 3 ventral setae. Female GA 125 long, 70 wide; with 6 pgs. Genital sclerite with pair of small sgs. Male GA 138 long, 100 wide; with 22 pgs. Spermatopositor is large, 75 long, 50 wide, extending beyond genital opening by almost 1.5 times ( Figs. 11 A, B ). Gnathosoma 100 long and 60 wide; 1.6 times longer than wide. Rostrum triangular and extending slightly beyond of P-2. Tectum truncate ( Figs. 11 C, D ). Legs slender. Leg I 350 long. The chaetotaxy of leg I as follows (from trochanter to tarsus); 1, 2, 5, 4, 7, 6 ( Fig. 11 E ). Tarsi II, III and IV with 3, 3 and 2 setae respectively ( Figs. 11 F–H ). Copidognathus quadricostatus belong to the tricorneatus group which contains 14 species around the world including C. adriaticus , C. andhraensis , C. dictyotellus , C. dictyotus , C. hummelincki , C. kagamili , C. leptoporus , C. longipes , C. megaloporus , C. mucronatus , C. quadricostatus , C. tricorneatus , C. trouessarti and C. xaixaiensis ( Bartsch 1991; Otto 2001; Chatterjee et al. 2004). Copidognathus quadricostatus is most similar to C. mucronatus and C. trouessarti . C. quadricostatus can be distinguished from C. mucronatus on the basis of the reticulation of the PD (meshes of the reticulum subdivided in C. mucronatus but undivided in C. quadricostatus ) and outline of the porose areolae on the AE and GA (porose areolae in C. mucronatus smaller than C. quadricostatus ). Copidognathus trouessarti has a much longer, slender rostrum, and the arrangement of the maxillary setae is different (apical pair of maxillary setae inserted in basal quarter of rostrum or level with end of P-1) from the other species ( Bartsch 1991; 1997; 2001).

Distribution. Eastern Northatlantic, Mediterranean and Black Sea ( Bartsch 2009).
