BD90013D73603A6DD3CC7ECD10F226C7.taxon	discussion	Comparisons. Pseudochromis lugubris appears to be closely related to P. bitaeniatus from throughout the West Pacific, and P. tonozukai from off northern Sumatra. They resemble each other, and differ from other pseudochromids, in having a combination of two heavily pigmented stripes on the body (indistinct in P. lugubris and large P. bitaeniatus), which converge on the midposterior part of the caudal fin, and a rhomboid to trifurcate caudal fin (though this is weakly developed in P. lugubris). They are readily distinguished by several meristic characters (Table 1): dorsal-fin rays (25 - 27, usually 26 in P. bitaeniatus, 26 - 27 in P. lugubris, and 25 in P. tonozukai); scales in lateral series (42 - 47 in P. bitaeniatus, 48 - 50 in P. lugubris, and 34 - 36 in P. tonozukai); anterior lateral-line scales (27 - 35 in P. bitaeniatus, 30 - 38 in P. lugubris, and 25 - 27 in P. tonozukai); and circumpeduncular scales (18 - 20 in P. bitaeniatus, 20 in P. lugubris, and 16 in P. tonozukai). Pseudochromis tonozukai has longer pelvic fins than the other two species (second segmented pelvic-fin ray 29.3 - 30.7 % SL versus 18.4 - 24.4 % SL in P. bitaeniatus and 19.8 - 24.4 % SL in P. lugubris), though we anticipate considerable ontogenetic variation in this character. The three species also differ markedly in coloration details (compare Figs 1, 3 and 4 - 5), though, as noted above, P. lugubris has similar preserved and live coloration patterns to large specimens of P. bitaeniatus (see further comments below on possible ontogenetic variation in P. lugubris).

BD90013D73603A6DD3CC7ECD10F226C7.taxon	etymology	Remarks. The specific epithet is from the Latin, meaning “ mournful, ” alluding to the relatively sombre coloration and the tear-like marking beneath the eye.	en	Anthony C. Gill, Gerald R.

BD90013D73603A6DD3CC7ECD10F226C7.taxon	discussion	The observation that the broad dark stripes are more prominent in small specimens of P. lugubris suggests that they may be even more conspicuous in small juveniles. This is further suggested by ontogenetic variation in the related P. bitaeniatus (Gill 2004). Michael (2004) included a photograph of this species from Milne Bay, Papua New Guinea. He suggested that it might be conspecific with a species he termed the “ Togean dottyback, ” photographed by R. H. Kuiter at Tomini Bay, Togean Islands, Indonesia. Although specimens are lacking from this locality to verify their identification, Kuiter’s photographs (one of which was preproduced by Michael, 2004: 121; an additional photograph was sent to the first author by R. H. Kuiter) are almost certainly of large individuals of P. bitaeniatus.	en	Anthony C. Gill, Gerald R.

CDAC0CE191DDEDC4D362AB266F656242.taxon	discussion	Comparisons. Pseudochromis tonozukai appears to be related to P. bitaeniatus and P. lugubris. Characters distinguishing the three species are discussed under Comparisons for P. lugubris. Pseudochromis tonozukai might also be confused with P. reticulatus Gill and Woodland (1992) from northwestern Australia and P. pictus Gill and Randall (1998) from Alor Island, Indonesia. Both of these species have a pointed caudal fin (rounded with the middle rays produced) and are pale with dark reticulations on the upper part of the body. However, neither species has a stripe on the lower part of the body, and both have more segmented dorsal-fin rays than P. tonozukai (26 - 27 versus 25). Pseudochromis pictus further differs in having more circumpeduncular scales (20 versus 16). Due largely to the unusual caudal-fin shape, specimens of P. tonozukai will not key unambiguously beyond couplet 52 of Gill’s (2004) key to Pseudochromis species. It is readily distinguished from species at or following that couplet in having the following character combination: caudal fin rhomboid to trifurcate; segmented dorsal-fin rays 25; segmented anal-fin rays 14 - 15; and upper part of pectoral fin without small dark spot. The live and preserved colorations also readily distinguish P. tonozukai from these and all other pseudochromid species.	en	Anthony C. Gill, Gerald R.
