Abstract

Two new species of the denticulata-group in the genus Ceratophysella Börner, 1932, C. rogerarlei sp.n. and C. nataliae sp.n., both from Brazil are described and illustrated. Ceratophysella rogerarlei sp.n. is similar to C. engadinensis (Gisin, 1949) in overall chaetotaxy, but it is unique by the combination of Ant. IV with trilobed apical bulb and 5 dorsal sensilla, PAO atypical with antero-lateral lobe clearly shorter than the antero-medial lobe, and the reduction of trunk dorsal chaetotaxy and number of macrosetae. Ceratophysella nataliae sp.n. is similar to C. gibbosa (Bagnall, 1940) and C. tupamara Palacios-Vargas & Bocanegra, 2012 but differs in dorsal abdominal chaetotaxy, Ant. IV with trilobed apical bulb (simple in C. gibbosa) and dorsal manubrium with 18+18 setae (8+8 in C. tupamara). A key to South American species of the genus is provided. With the descriptions presented, there are now nine species of Ceratophysella recorded from South America and six from Brazil.

标题巴西角鼻虫属二新种(弹尾纲:拟角鼻虫科)及南美角鼻虫属一键

CeratophysellaBörner属小齿群二新种，1932,C. rogerarlei sp.n.。和C. nataliae;，这两种都来自巴西。角鼻苔属。与C. engadinensis (Gisin, 1949)在总体毛分类学上相似，但其独特之处在于与Ant的组合。IV型为三叶状顶端鳞茎和5个背侧感受器，PAO不典型，前外侧裂片明显短于前内侧裂片，躯干背侧毛性减少，大刚毛数量减少。角鼻苔属;与C. gibbosa (Bagnall, 1940)和C. tupamaraPalacios-Vargas & Bocanegra, 2012相似，但在背腹毛分类上有所不同。IV具三叶顶端球茎(在C. gibbosa单一)和背柄具18+18刚毛(在C. tupamara 8+8)。提供了南美种的钥匙。根据上述描述，目前在南美洲有记录的角鼻虫有9种，在巴西有记录的有6种。

期刊介绍： Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
