TL;DR: Revision of the blenniid fish genus Omobranchus, native to the Indo-west Pacific, and all taxa, except one subspecies, occur only in areas west of the Andesite Line, where one species, O. punctatus, has been introduced into the Caribbean.
Abstract: Springer, Victor G., and Martin F. Gomon. Revision of the Blenniid Fish Genus Omobranchus with Descriptions of Three New Species and Notes on Other Species of the Tribe Omobranchini. Smithsonian Contributions to Zoology, number 177, 135 pages, 52 figures, 17 tables, 1975.—Omobranchus comprises 19 species, one of which includes two subspecies. Three species are described as new: O. meniscus, from Thailand, O. steinitzi, from the southern Red Sea, and O. verticalis, from Queensland. A key is given to all taxa of Omobranchus, and sexual dimorphism, geographic distribution and variation, habitat, and nomenclature are discussed. All taxa are illustrated and their distributions plotted on maps. Neotypes are designated for the following species: Blennechis fasciolatus Valenciennes (1836), Petroscirtes lineolatus Kner (1868a,b), Petroscirtes ferox Herre (1927). Omobranchus is native to the Indo-west Pacific, and all taxa, except one subspecies, occur only in areas west of the Andesite Line. One species, O. punctatus, has been introduced into the Caribbean. Circumstantial evidence indicates that O. punctatus was probably introduced by ships transporting East Indian coolies from Madras and Calcutta around southern Africa to the Caribbean between 1845 and the opening of the Panama Canal (1914). New information (range extensions, taxonomy, errata), since Springer's 1972 Synopsis of the Tribe Omobranchini, is given for the genera Enchelyurus, Haptogenys, Omox, and Parenchelyurus. Haptogenys quadripora Springer is synonymized with H. bipunctata (Day).

TL;DR: P phylogenetic analyses of one mitochondrial (CO1) and four nuclear (ENC1, myh6, sreb2, and tbr1) genes provide evidence for the monophyly of Omobranchus and support for the elongatus and banditus species group.
Abstract: The combtooth blenny (Blenniidae) genus Omobranchus contains small, cryptobenthic fishes common to nearshore habitats throughout the Indo-West Pacific. Recent molecular systematic studies have resolved Omobranchus as monophyletic but little research has been done to resolve species-level relationships. Herein, phylogenetic analyses of one mitochondrial ( CO1 ) and four nuclear ( ENC1 , myh6 , sreb2 , and tbr1 ) genes provide evidence for the monophyly of Omobranchus and support for the elongatus and banditus species group. Sampling of multiple individuals from widespread species ( O. ferox , O. punctatus , and O. elongatus ) suggested that the Thai-Malay Peninsula is a phylogeographic break that may be a historic barrier to gene flow. Additionally, common meristics and other morphological characters are used to describe an early life history stage of O. ferox and O. punctatus.
TL;DR: The family Pteriidae (Bivalvia: Pterioida), which includes he group known as, pearl oysters," comprises three Recent genera, Pteria Scopoli 1777, Pinctada Roding, 1798, and Electro117a Stolickza 1871 but no species of Electroma has yet been reported from either Recent Atlantic or eastern Pacific fauna.
Abstract: The family Pteriidae (Bivalvia: Pterioida), which includes he group known as , pearl oysters," comprises three Recent genera, Pteria Scopoli 1777, Pinctada Roding, 1798, and Electro117a Stolickza 1871 (Hayes 1972; Vaught, 1989). This family i considered to be represented in American waters (in both the western Atlantic and the eastern Pacific) by nine recognized pecie belonging to the genera Pteria and Pinctada (Hayes, 1972) but no species of Electroma has yet been reported from either Recent Atlantic or eastern Pacific fauna. There is comparatively little information on recent invasions of marine organisms to the western Atlantic. Although a number of introductions may have occurred, they have not been rec gnized. At least four recent introductions of bent.hic marine organ.isms to the tropical western Atlantic have been interpreted as due to shipping activities specifically transport of ballast water: the algal commensal shrimp Hippolyte wstericola from other Atlantic locations (Wicksten, ] 989), the swimming crab Chalybdis helleri from the Indo-Pacific and I rael (Campos and Tiirkay, 1989), the green mussel Perna viridis from the Indo-Pacific to Trinidad and Tobago (Agard et aI., 1992) and possibly the Texas coa t (Hicks and Tunnell, 1993; Carlton, pers. comnl.), and tl1e blenniid fish Omobranchus pUl1ctatus from the Indo-Pacific to the northern coast of South Amelica (Springer and Gomon, 1975). The present report of the pteriid bivalve Electroma sp. i an addition to this growing list.
TL;DR: All reported species, except the endemic Makran comb-tooth blenny, Omobranchus mekranensis , Vulnerable) are considered as Least Concern (LC).
Abstract: The present study provides a checklist of the family Blenniidae from intertidal habitats along the Iranian coasts of Persian Gulf and Makran Sea. This research carried out during the years 2013-2018 at nine stations (Dayyer, Haale, Bostanou, Bandar Lenge, Qeshm, Gataan, Jask, Gugsar and Chabahar) with almost rocky profile covering whole distribution range of the family. A total of 15 species including 11 species from collection sites and four species from previous works are listed here : Alticus kirkii, Antennablennius adenensis, A. bifilum, A. variopunctatus, Istiblennius edentulus, I. lineatus, I. pox, I. spilotus, Parablennius cornutus, P. opercularis, P. pilicornis and Scartella emarginata (subfamily Salariinae); Omobranchus fasciolatus, O. mekranensis and O. punctatus (subfamily Blenniinae). The most diverse genus is Istiblennius (four species, 26.6%) followed by Antennablennius, Parablennius and Omobranchus (each with three species, 20%), Alticus and Scartella (each with one species, 6.6%). All reported species, except the endemic Makran comb-tooth blenny, Omobranchus mekranensis , Vulnerable) are considered as Least Concern (LC).
