Abstract

We examined the diversity and host use of sponge-associated barnacles of Thailand (Andaman Sea and the Gulf of Thailand) using a combined morphological and molecular approach. Eight barnacle species (including two new species) were collected from 12 host sponges. Host-specific barnacle species includes Acasta lappasp. nov., which exclusively inhabits the sponge Mycale sp. Acasta milkaesp. nov. was only collected from the sponge Callyspongia cf. diffusa (Ridley, 1884). Multatria filigranus (Broch, 1916) were found in the encrusting soft sponges Monanchora unguiculata (Dendy, 1922) and Clathria sp. Pyrgospongia stellula (Rosell, 1975) inhabits the sponges Spheciospongia vagabunda (Ridley, 1884). Generalist barnacle species includes Euacsta ctenodentia (Rosell, 1972), E. porata (Nilsson-Cantell, 1921), E. zuiho (Hiro, 1936), and Acasta cyathus Darwin, 1854, which inhabit a wide range of sponges with various textures.

泰国海绵相关藤壶（Cirripedia：Thoracica）的生物多样性和寄主特异性

摘要

我们使用形态学和分子学相结合的方法研究了泰国（安达曼海和泰国湾）与海绵相关的藤壶的多样性和宿主用途。从12个宿主海绵中收集了8种藤壶物种（包括2种新物种）。寄主特有的藤壶物种包括Acasta lappa sp.。十一月 ，仅居住在海绵Mycale sp。上。Acasta milkae SP。十一月 仅从海绵Ç收集allyspongia比照 diffusa（Ridley，1884）。在包裹柔软的海绵Monanchora unguiculata（Dendy，1922年）和Clathria sp。中发现了Multatria filigranus（Broch，1916年）。Pyrgospongia stellula（Rosell，1975）居住在海绵Spheciospongia vagabunda（Ridley，1884）中。通才藤壶物种包括Euacsta ctenodentia（Rosell，1972），E。porata（Nilsson-Cantell，1921年），E。zuiho（Hiro，1936年）和Acasta cyathus达尔文，1854年，居住着各种质地各异的海绵。
