Treatment

Copidognathus gibbus (Trouessart, 1889) ( Figs. 4 A–E View Figure 4 )

Material examined Yakamoz Beach, 2 m, fine sand, 6 ♀♀, 4 ♂♂.

Morphology and notes

Females 330–338 long, 165–170 wide, of male 320–325 long, 170–175 wide. Idiosoma anteriorly with pointed protuberance. AD as long as wide (125); has “A” shaped internal sclerite. AD rectangular posteriorly. OC 73 long, 25 wide; PD 187 long, 130 wide. Porose costae on PD 3–5 pores wide. ds-1 on AD, ds-2 on OC and ds-3 to ds-5 on PD. ds-5 quite long (75 long). AE with

three pairs of ventral setae. PE with 1 dorsal and 3 ventral setae. AE 120 long, 163 wide. Posterior margin of AE truncate. Female GA 150 long, 125 wide; with 3 pairs of pgs. Male GA 188 long, 125 wide; with 20 pgs ( Figs. 4 A–C View Figure 4 ). Gnathosoma 85 long, 60 wide; 1.4 times longer than wide and lateral areas punctated. Rostrum triangular, shorter than gnathosomal base, extending level of P-3. Gnathosomal base with 2 pairs of setae ( Fig. 4 D View Figure 4 ). Leg I 212 long. The chaetotaxy of leg I as follows (from basifemur to tarsus); 1, 2, 5, 3, 7, 8. Legs with large lamellae; basifemora-I with small ventral lamellae, telofemora-I with large ventral lamellae, tibiae with posterior articular lamellae ( Figs. 4 E–H View Figure 4 ). This species belongs to the gibbus group which has about 42 described species from all over the world. Characteristics of the gibbus group are: legs with large lamellae, AD characterized by an “A” shaped internal sclerite ( Bartsch 1994; 1997). Copidognathus gibbus is most similar to C. majusculatus . Distinguishing characters of the two species are discussed in C. majusculatus below.
