88B739F542C5543090387E279D6BA746.taxon	diagnosis	Diagnosis. A species of Egglestonichthys (Fig. 1) with the following combination of characters: anal-fin rays I, 9; pectoral-fin rays 17, lower rays connected by membrane; longitudinal series scales 25; transverse scales 8; pre-dorsal-fin scale rows 8; cheek and opercle naked (Fig. 2 B); pelvic frenum absent; caudal fin lanceolate, its length 32.2 % of SL; interorbital width very narrow, 1.2 % of HL (much narrower than pupil diameter) (Fig. 2 A); no spicules or odontoid processes on outer surface of gill arches; and body whitish, upper half with broken zigzag pattern of bright yellow patches and associated scattered black melanophores in fresh specimens (melanophores retained in preserved specimens) (Fig. 1 A, B).	en	Fujiwara, Kyoji, Suzuki, Toshiyuki, Motomura, Hiroyuki (2020): A new species of Egglestonichthys (Teleostei, Gobiiformes, Gobiidae) from Okinawa Island, Japan.

88B739F542C5543090387E279D6BA746.taxon	description	Description. Dorsal-fin rays VI + I, 10; anal-fin rays I, 9; pectoral-fin rays 17; segmented caudal-fin rays 16; caudal-fin ray pattern 9 / 7; branched caudal-fin rays 7 / 5; unsegmented (procurrent) caudal-fin rays 6 / 6; longitudinal series scales 25; transverse scales 8; pre-dorsal-fin scale rows 8 (counted from scale pockets); circumpeduncular scales 12; gill rakers on outer face of first arch 3 + 11 (counted on right side); vertebrae 10 + 16. The following morphometrics are expressed as percentage of SL (% of HL in parentheses): head length 30.3; head depth 16.7 (55.1); head width 18.3 (60.6); body depth 14.9; body width 12.9; caudal-peduncle length 19.1, depth 9.4; snout length 5.9 (19.3); eye diameter 7.3 (24.0); interorbital width 0.4 (1.2); upper-jaw length 11.8 (39.0); pectoral-fin length 31.0; pelvic-fin length 28.1; caudal-fin length 32.2; and longest dorsal-fin spine (2 nd) length 12.8. Body slender, compressed, width much less than depth (Fig. 1 A, B). Anus situated just before anal-fin origin. Head short, depressed anteriorly, its width slightly greater than height. Snout short (slightly shorter than eye diameter), rounded, slightly inflated. Anterior and posterior nostrils close to each other; former located just above anterior upper lip, much larger than latter, with long membranous tube; latter located between snout tip and anterior margin of eye, small, circular. Eye moderate, located dorsolaterally. Interorbital region very narrow, flattened. Mouth terminal, anteriorly inclined obliquely upwards. Lower jaw longer than upper jaw, its posterior tip reaching back to vertical through middle of pupil. Upper-jaw tip behind vertical through lower-jaw tip. Both jaws with two or three irregular rows of small, pointed conical teeth, the tip of each slightly curved posteriorly. Gill opening wide, anteroventral point extending slightly forward to vertical level of preopercle margin, gill membranes attached anteriorly to isthmus. Preopercular and opercular margins slightly pointed and rounded, respectively, upper end of latter horizontally level with middle of eye. Gill rakers sharp, slender. Outer surfaces of gill arches lacking spicules or odontoid processes. Head lacking sensory canal pores (Fig. 2). Head sensory papillae (many damaged by abrasion and unobservable) in transverse pattern on cheek (possibly more complex in undamaged condition); two rows of longitudinal papillae under head (Fig. 2). Body covered with relatively large cycloid scales. Pre-dorsal- and pelvic-fin regions covered with cycloid scales; anterior margin of pre-dorsal-fin scales reaching to vertical through preopercle margin; pre-pelvic-fin scales reaching to just behind anteroventral point of gill opening. Pectoral-fin base with 2 relatively large cycloid scales. Side of head (snout, suborbital region, jaws, cheek, and opercle) naked (Fig. 2). First dorsal fin triangular, 2 nd spine longest, all spines lacking filamentous tips; dorsal-fin origin located posterior to vertical through pectoral-fin base; all spines thin, flexible. Second dorsal and anal fins long, origin of latter under base of 1 st dorsal-fin soft ray, anterior 1 - 3 rays of both fins somewhat short, thereafter subequal in length (longer than dorsal-fin spines), last rays well separated from caudal-fin base. Pectoral fin long, pointed, middle rays longest, tips reaching to below origin of 2 nd dorsal-fin soft ray; all rays connected by membrane, uppermost and lower 3 rays unbranched. Pelvic fins completely connected by membrane, without frenum; posterior tip reaching below 2 nd dorsal-fin origin when appressed; pelvic-fin origin located just below ventral end of pectoral-fin base. Caudal fin lanceolate, its length much greater than head length.	en	Fujiwara, Kyoji, Suzuki, Toshiyuki, Motomura, Hiroyuki (2020): A new species of Egglestonichthys (Teleostei, Gobiiformes, Gobiidae) from Okinawa Island, Japan.

88B739F542C5543090387E279D6BA746.taxon	etymology	Etymology. The specific name " Egglestonichthys fulmen " is derived from Latin, meaning " lightning ", in reference to the bright yellow zigzag pattern on the upper part of the body.	en	Fujiwara, Kyoji, Suzuki, Toshiyuki, Motomura, Hiroyuki (2020): A new species of Egglestonichthys (Teleostei, Gobiiformes, Gobiidae) from Okinawa Island, Japan.
