Abstract
Seventy-five specimens of Nephropid lobsters captured using bottom trawls at 24 stations in the Indian Ocean include nine species ofNephropsis, three species ofMetanephrops and one species ofThymopides, among which four species ofNephropsis are new to science. Thelyca of females and gonopods of males are described for the first time in some species. Some data concerning fecundity, i.e. the numbers of eggs attached to pleopods of females, are provided. All species examined have a hitherto unknown structure on pereopod 5, which is presumably a “stridulating organ”. In the northern part of the Indian Ocean the nephropids are found deeper compared to their depth range in other areas. This is thought to be a result of warm, deep water masses from the Red Sea and the Gulf of Oman.
Kurzfassung
An 24 Stationen im Indischen Ozean mit Bodentrawls gesammelte nephropide Hummer (75 Individuen) umfassen neun Arten vonNephropsis, drei Arten vonMetanephrops und eine Art vonThymopides, von denen vierNephropsis-Arten neu sind. Die Thelyca der Weibchen und die Gonopoden der Männchen einiger Arten werden zum ersten Mal beschrieben und abgebildet. Einige Daten zur Fekundität, insbesondere die Eizahl der Weibchen werden präsentiert. Alle untersuchten Arten haben auf ihrem 5. Pereopoden eine bisher unbekannte Struktur, die vermutlich ein Stridulationsorgan darstellt. Im nördlichen Teil des Indischen Ozeans weisen die Nephropiden im vergleich zu anderen Regionen eine Submergenz auf. Dies wird auf warmes Wasser aus dem Roten Meer und dem Golf von Oman zurückgeführt.
