“…With the exception of N. blanchardi and N. uninotatus the relative maxilla length is similar in N. stephensae , all members of the western Pacific clade [ N. okazaki, N. chihiro, N. bryope , N. nudus , N. monogrammus and N. nudiceps (Fukao, ; Murase et al, )] and the sister group of Neoclinus , M. sandae (Rosenblatt & Stephens, ), extending posteriorly to the level of the posterior orbital margin or slightly beyond it. The maxilla of N. uninotatus is relatively longer, extending well past the orbit to just before the posterior margin of the preopercle, while that of N. blanchardi is even longer, extending well‐past the posterior margin of the head.…”

“…Blenniiform fishes of the genus Neoclinus are known to show the gaping display for territorial defense. Neoclinus includes eleven species of benthic shallow‐water fishes, three in the eastern Pacific from northern California to Baja California ( N. blanchardi , N. uninotatus , and N. stephensae ; Hubbs, ), and eight in the western Pacific from South Korea to northern Taiwan (Fukao, ; Love, ; Murase, Aizawa, & Sunobe, ). Phylogenetic relationships based on morphological characters and molecular data (Hongjamrassilp, ) reveal that the eastern Pacific species form a monophyletic group with N. blanchardi sister taxon to N. uninotatus , and both are sister taxa to N. stephensae .…”

The Sarcastic Fringehead (Neoclinus blanchardi, Teleostei) exhibits an extreme version of a common aggressive display, the "gaping display," in which an open mouth is presented toward an opponent. Males of this species have extremely long jaws that extend posteriorly well past the posterior margin of the head and are flared laterally during the gaping display. In this study, we explored morphological traits related to this extraordinary display in this and related species of blennies. Morphological modifications include enlargement of the buccopalatal membrane, elongation of the maxilla via an uncalcified posterior extension, and evolution of a novel hinge between the anterior maxilla and lacrimal bones permitting lateral movement of the upper jaw. Geometric morphometry using the truss network system, thin-plate spline, and PCA of three closely related species of Neoclinus indicate that the elongate maxilla of N. blanchardi most likely evolved via acceleration (faster growth compared to outgroups) and hypermorphosis (continued growth to a larger body size), both forms of peramorphic heterochrony. Coloration and fluorescence of the buccopalatal membrane may also serve to amplify the extraordinary gaping display of the Sarcastic Fringehead.

“…The only chaenopsids not occurring in this region are Emblemaria hudsoni, which is restricted to Peru (Stephens, 1963), and the genus Neoclinus, the hypothesized sister group of all other chaenopsids (Hastings & Springer, 1994). Neoclinus includes nine species found in the North Pacific from California to Japan and Taiwan (Stephens & Springer,197 1; Fukao, 1980Fukao, , 1990. Chaenopsids are small (usually less than 50 mm SL), benthic fishes restricted to rocky-and coralreef substrates and their surrounding rubble zones.…”

Biogeography of the Tropical Eastern Pacific: distribution and phylogeny of chaenopsid fishes

The Tropical Eastern Pacific Biogeographic Region (TEP) is delimited by steep thermal gradients to the north and south, by a wide expanse of open ocean (the East Pacific Barrier) to the west, and by the Central American land mass to the east. Four provinces within the TEP have been recognized based on the distribution of rocky shore fishes and marine invertebrates: the Cortez, Mexican, Panamic, and Galapagos Provinces. For rocky shore fishes, hypothesized barriers between these provinces are areas lacking rocky outcroppings, specifically the Central American Gap between the Panamic and Mexican Provinces, the Sinaloan Gap between the Mexican and Cortez Provinces, and the Pelagic Gap between the mainland and the Islas Galapagos. The occurrence of 33 chaenopsid fish species within these provinces, as well as other oceanic islands or archipelagos in the TEP (Isla de Malpelo, Isla del COCO, and Islas Revillagigedo) were tallied based on literature records and observations of museum specimens. Chaenopsid distributions within the TEP support these hypothesized provinces and their intervening gaps. Twenty-one species (64% of the TEP chaenopsid fauna) are restricted to a single mainland province or one of the oceanic islands or archipelagos.Of the mainland provinces, the Cortez and Panamic exhibit similar levels of endemism (50%), but the Mexican Province has only one endemic (lOo/o). Of the remaining chaenopsids in the Mexican Province, three are widespread, occurring in all three mainland provinces, four are shared only with the Cortez Province, and two are shared only with the Panamic Province. Within the TEP, the Pelagic Gap is the most effective (crossed by only 3 of 33 species adjacent to it), followed by the Central American Gap (crossed by 5 of 21 species), and the Sinaloan Gap (crossed by 7 of 17 species). Only one species, Chaenopsis alepidota, which is found off southern California and in the Cortez Province, crosses a barrier delimiting the TEP. Species-level phylogenetic hypotheses for the Chaenopsidae imply exclusively allopatric speciation for these fishes in the TEP. Of the barriers delimiting the TEP, the most important in the recent evolution of chaenopsids is the Isthmian Barrier which is implicated in six speciation events. Within the TEP, the Central American Gap and Sinaloan Gap are each implicated in three speciation events, while the Pelagic Gap is implicated in three speciation events of island endemics from mainland populations and one inter-island speciation event.

“…Chaenopsid fishes, occurring in Korean waters, have previously been known only as two species (N. bryope and N. chihiroe), but an additional species has now been reported through this study. The ecological characteristics of chaenopsid fishes are known that they do not have large movements and inhabit small caves between rocks or in empty gastropod tubes (Stephens and Springer 1971;Fukao and Okazaki 1987;Fukao 1990). Due to this characteristic, their distribution ranges are expected to be considerably narrow (Hongjamrassilp et al 2020).…”

One specimen (38.3 mm SL) of Neoclinus lacunicola Fukao, 1980, belonging to the family Chaenopsidae, was first recorded from Ulleung Island, Korea (East Sea, otherwise known as the Sea of Japan) on 5 January 2021. This species was characterized by paired external pores of incomplete lateral line running from the upper margin of the opercle, seven pairs of supraorbital cirri arranged in two rows, occipital region with a pair of cirri, and 13 rays of pectoral fin. This species is morphologically similar to the Neoclinus toshimaensis Fukao, 1980, but differs in the number of cirri on the supraorbital (6–7 versus 9–11 cirri). This study documents the first report of N. lacunicola in Korean waters and proposes the new Korean name of ‘eol-lug-bi-neul-be-do-la-chi’ for the species. For the confirmation of the identity of the species, a partial gene sequence of the mt COI (570 bp) of N. lacunicola was obtained for the first time.
