Color
Following descriptions of coloration when alive are based on underwater photographs. Ground color of head and body blackish or dark grayish-brown; Broad mid-dorsal pale or pale beige stripe, extending from snout tip to, or beyond, base of fifth spine of first dorsal fin through dorsal part of eye; Two small pale beige saddles at posterior end of base of second dorsal fin and caudal peduncle; Sometimes an additional small pale beige saddle, continuous with whitish anteroventral corner of second dorsal fin, present at second dorsal-fin origin; Anterior narial tube whitish; Anteroventral part of first dorsal fin whitish; Remaining part of first dorsal fin dark yellowish-brown, gradually changing to white at distal one-half or one third of fin; A dark gray brown spot, subequal to or slightly smaller than eye, at center of first dorsal fin behind fourth spine; second dorsal fin dark grayish-brown or dark yellowish-brown, gradually becoming subtranslucent distally, with or without whitish anteroventral corner (whitish area often expanded a little onto body); Anal fin dark grayish brown, with slightly paler distal margin and a small white blotch at anterodorsal part; Caudal fin translucent (exclusive of narrow basal dark grayish-brown area), with 5–8 pupil-sized (or slightly larger) dark grayish brown submarginal spots; Pectoral fin translucent, exclusive of narrow blackish basal area with two white spots dorsoventrally; Several pupil-sized black spots at middle and submerginal parts of petoral fin; Pelvic fin dark grayish brown, with a white spot around spine.

Etymology
Lotilia: etymology unknown.
klausewitzi: the species is named klausewitzi in honour of W. Klausewitz (born July 20, 1922). He is a German zoologist, ichthyologist, marine biologist and biohistorian, who described many Indo-Pacific fishes, including the genus Lotilia.
Original description: Lotilia klausewitzi Shibukawa, Suzuki & Senou, 2012 - Locality type: Yonehara, Ishigaki-jima Island, Yaeyama Group of Ryukyu Islands, Japan, 7 July 1980, hook & line (collected by T. Suzuki & H. Senou).

Biology
Lotilia klausewitzi lives around reef patches on sandy bottoms with rubble, in coral-reef moats and lagoons, outer-reef slopes, or under drop offs. It is symbiotically associated with a snapping shrimp, Alpheus rubromaculatus (Karplus, Szlep & Tsurnamal, 1981), and usually hovers just above the burrow entrance. This species constantly waves its fan-like pectoral fins in an ungoby-like manner.

Similar species
Cryptocentrus malindiensis (Smith, 1959) - Reported from East Africa to Madagascar and Réunion (western Mascarenes).
Lotilia graciliosa (Klausewitz, 1960) - Reported from Northwest Indian Ocean: Red Sea and Gulf of Aden. The two fish belonging to the genus Lotilia are allopatric species which means that they do not co-exist or have overlapping ranges and they look pretty different too.
