03A987EBFF9DFFADFEC1F8D9D8A07982.taxon	discussion	REMARKS Among the 14 species of Catapagurus that have blade-shaped dactyls on pereopods 2 and 3, this new species is most similar to three of those species in having weakly blade-shaped dactyls. Those three species are: C. fimbriatus Komai & Rahayu, 2021, C. insolitus Komai & Osawa, 2009, and C. tenuilamina Komai, Miller & Malay, 2022. However, that is where the similarity ends as there are a number albeit subtle characters that set C. poupini n. sp. apart from those other three. This new species differs from Catapagurus fimbriatus as follows: shape of shield (barely broader than long in the new species vs distinctly broader than long in C. fimbriatus); shape of cornea (roughly as broad as long in the new species vs distinctly broader than long in C. fimbriatus); teeth on cutting edge of dactyl of right chela (armed with minute blunt teeth proximally and a distal rounded tooth in the new species vs having two unequal prominent blunt teeth in C. fimbriatus); development of rasp on propodus of pereopod 4 (consisting of a long row of small scales in the new species vs a short row of relatively large scales in C. fimbriatus); presence / absence of male gonopore on left coxa (present in the new species vs absent in C. fimbriatus); and, telson lateral indentations and shape of posterior lobes (with distinct lateral indentations, and U-shaped median cleft separating terminally blunt posterior lobes in the new species vs wide trapezoidal median cleft separating terminally acute posterior lobes in C. fimbriatus). This new species differs from Catapagurus insolitus as follows: the shape and armature of antennal acicles (slender and unarmed mesially in the new species vs stout and armed with distinct spines mesially in C. insolitus); length of pereopod 4 preungual process (short and barely exceeding dactyl claw in the new species vs long and distinctly exceeding dactyl claw in C. insolitus); and, telson posterior lobes (separated by deep U-shaped median cleft in the new species vs separated by a a subrectangular median cleft in C. insolitus). This new species differs from Catapagurus tenuilamina as follows: length of pereopod 4 preungual process (short and barely exceeding dactyl claw in the new species vs long and distinctly exceeding dactyl claw in C. tenuilamina); teeth on cutting edge of dactyl of right chela (armed with minute blunt teeth proximally and a distal rounded tooth in the new species vs one large blunt subtriangular tooth proximally and low round teeth distally in C. tenuilamana); armature of ventromesial margin of dactyl of pereopods 2 and 3 (with one row of about six minute corneous spinules in the new species vs with one row of about 20 minute spinules in C. tenuilamina); presence / absence of male gonopore on left coxa (present in the new species vs absent in C. tenuilamina); and terminal shape of sexual tube (bilobed with one low lobe slender, elongated vs bilobed with both lobes short and rounded in C. tenuilamina).	en	Lemaitre, Rafael (2025): Two new species and new records of Catapagurus A.

03A987EBFF92FFA4FF2FF895DC237982.taxon	description	Color Unknown. REMARKS A B D A, C B, D E C E Previously known from the Coral and Tasman Seas and New Caledonia (McLaughlin 2004), the range is herein extended to approximately 900 km eastward to the Fiji Islands, including the Solomon Islands and Vanuatu. The morphological variations documented in this species by McLaughlin (2004) have all been observed in the material herein reported, which are mostly related to size or growth of the specimens. Most evident in the material examined during this study is the influence of size and growth of the specimens on the dorsal armature of the meri of the second and third pereopods, which can diminish in sharpness and strength with increasing size. In contrast, the sexual tubes of specimen tend to be longer in smaller specimens where the tube can extend entirely over the dorsal surface of the pleon, whereas in larger males the tube usually partially curves over the pleon. The shape and armature of the telson can also vary significantly, with the posterior lobes separated by a narrow V-shaped cleft, or in some specimens by a broad U-shaped cleft.	en	Lemaitre, Rafael (2025): Two new species and new records of Catapagurus A.
