Abstract

The morphology of the inorganic scales of ten species of centrohelid heliozoans collected from various types of aquatic habitats in Vietnam has been examined. All the species identified are new to Vietnam. The spine scales of Acanthocystis turfacea are distinguished by the characteristic conically pointed tips of furcae and longer furcae relative to the shaft length in long spine scales. Morphologically, the plate scales of Pterocystis tropica examined correspond to those of the subspecies P. tropica paucistriata; the spine scales, to those of the subspecies P. tropica tropica. The examined plate scales of Raineriophrys erinaceoides undulata lack radial slits, unlike those indicated in the original description of this subspecies. Two new species of centrohelid heliozoans are described. Pterocystis vietnamica sp. n. is characterized by leaf-shaped spine scales with transverse slits on the lateral wings and a large, spherical, subapical protrusion. Pseudoraphidocystis dentata sp. n. has marginal teeth at the edges of funnel-shaped spine scales.

摘要

考察了从越南各种水生生境中收集到的十种中心螺旋日生动物的无机鳞片的形态。确定的所有物种都是越南新来的。棘面棘鳞片的特征在于,相对于长脊椎鳞片的杆身长度,圆锥形的圆锥形尖端和较长的圆锥形尖端。形态学上,的板鳞Pterocystis tropica检查对应于那些亚种的P. tropica paucistriata ; 脊椎鳞片,到热带 亚种P. tropica tropica检疫的鳞翅目鳞片鳞片与该亚种的原始描述不同,它没有放射状的缝隙。描述了两种新的中心螺旋日生动物。越南Pterocystis sp。。其特征是叶形的脊椎鳞片,在侧翼上有横向的缝,并有一个大的球形亚尖突。Pseudoraphidocystis齿叶藻。。在漏斗形的脊柱鳞片的边缘有边缘的牙齿。
