( Figure 5View FIGURE 5)

Callogobius dori Goren 1980: 210  (Suakin, Sudan, Red Sea; holotype BMNH 1978.9.8.7). Callogobius dori  —Dor 1984: 241; Goren et al. 1991: 299; Golani & Bogorodsky 2010: 46.

Diagnosis. Callogobius dori  is distinguished from congeners by the following combination of characters: interorbital pores B’, D, E, F, G and H’ present; preopercular canal absent; temporal canal absent; dorsal fin VI + I,9; anal fin I,7; scales in lateral series 24–26; body tan to dark brown with narrow, dark longitudinal stripes; a large diffuse black spot dorsally in caudal fin.

Brief description. Moderately stout-bodied with elongate, broadly rounded, caudal fin> 40% SL in length.

Scales large, deciduous, cycloid anteriorly, ctenoid from first spine of second dorsal fin to caudal-fin base, scales in lateral series 24–26. Dorsal-fin rays usually VI + I,9, anal-fin rays usually I,7, pectoral-fin rays 17–18, pelvic fins fully united with moderate frenum. Anterior nostril longer than posterior nostril. Head pores present with interorbital canal normally containing pores B’, D, E, F, G and H’, preopercular and temporal canals absent. Preopercular papillae row (Row 20) continuous with transverse opercular row (Row 21), more than 10 transverse mandibular papillae rows (Row 16) on each side.

Head, body and fins tan to brown. About seven or eight narrow, dark, longitudinal stripes usually visible on body. First dorsal and pectoral fins dark. Our specimens very faded, unable to discern whether or not vertical bars or head markings present. Dark spot as large as eye on upper part of caudal fin often present, depending on the condition of the specimen. Coloration in preservation similar.

Distribution and habitat. Western Indian Ocean and Red Sea. Callogobius dori  specimens have been collected from the base of coral patches on silty sand of a closed lagoon, depth 5–7 m, although one collection reached 21– 27 m.

Remarks. In the Red Sea, C. dori  is most likely to be confused with C. amikami  and C. pilosimentum  . Callogobius dori  shares a similar body shape and usually dark coloration with C. pilosimentum  ; it differs from the latter in lacking preopercular and temporal canals (vs. present), dorsal-fin spines not prolonged (vs. dorsal-fin spines prolonged, the second spine occasionally as a short filament), caudal fin> 40% SL in length (vs. <40% SL), and more than 10 transverse mandibular papillae rows on each side (vs. 4). Callogobius dori  shares a similar body shape and proportions with C. amikami  ; it differs from the latter in having second dorsal- and anal-fin ray counts of I,9 and I,7 respectively (vs. I,10 and I,8 respectively in holotype of C. amikami  ) and in color pattern (cf. Figs. 3View FIGURE 3, 5View FIGURE 5).

McKinney (1980) in an unpublished Master’s thesis refers to this species as Callogobius  new species B. One lot of C. dori  examined by McKinney ( USNMAbout USNM 220030View Materials, Red Sea, Gulf of Aqaba , Bay at El Himeira, 4 specimens) was labeled as “ C. aquilus  ”; this name was never published. Callogobius dori  has been considered a Red Sea endemic, but we have located three specimens from the Seychelles ( USNMAbout USNM 385746View Materials, Amirante Islands , St. Joseph Atoll, south of Ressource Island, 0–4 m, 7 March 1964), considerably expanding the known range of this species and suggesting it might be found elsewhere in the Western Indian Ocean  .
