Exocelina ekari-group在此介绍并主要根据aedeagus正中叶的不连续轮廓来定义。这个群体只在新几内亚（印度尼西亚和巴布亚新几内亚）为人所知。迄今为止，它包含4种：E. astrophallus （Balke, 1998）、E. atowaso （Shaverdo, Sagata & Balke, 2005）、E. munaso （Shaverdo, Sagata & Balke, 2005）和E. polita （Sharp, 1882）。本文描述了22个新种：大肠alexanderi sp. n。,大肠anggiensis sp. n。e . arfakensis sp. n。e .裂sp. n。e . brahminensis sp. n。e . bundiensis sp. n。e . edeltraudae sp. n。e . ekari sp. n。e .高速sp. n。e . evelyncheesmanae sp. n。e . hansferyi sp. n。e . irianensis sp. n。e . kakapupu sp. n。e . knoepfchen sp. n。e . oceai sp. n。e . pseudosoppi sp. n。e . soppi sp. n。e . unipo sp. n。e . utowaensis sp. n。e . waigeoensis sp. n。e . weylandensis sp. n。并指定了1882年politus Sharp Copelatus的选型。提供了所有种类的检查表和鉴定关键，并说明了重要的诊断特征（习性、颜色、雄性触角和4-5原体、中间裂片和参数）。提供了分布和生境要求的数据。迄今为止，E. ekari-group的代表主要来自新几内亚北部和中部的低地和低山区栖息地，该集团在高海拔地区的多样性较少。
The Exocelina ekari-group is here introduced and defined mainly on the basis of a discontinuous outline of the median lobe of the aedeagus. The group is known only from New Guinea (Indonesia and Papua New Guinea). It contained four species to date: E. astrophallus (Balke, 1998), E. atowaso (Shaverdo, Sagata & Balke, 2005), E. munaso (Shaverdo, Sagata & Balke, 2005), and E. polita (Sharp, 1882). Twenty two new species are described herein: E. alexanderi sp. n., E. anggiensis sp. n., E. arfakensis sp. n., E. bifida sp. n., E. brahminensis sp. n., E. bundiensis sp. n., E. edeltraudae sp. n., E. ekari sp. n., E. eme sp. n., E. evelyncheesmanae sp. n., E. hansferyi sp. n., E. irianensis sp. n., E. kakapupu sp. n., E. knoepfchen sp. n., E. oceai sp. n., E. pseudosoppi sp. n., E. soppi sp. n., E. unipo sp. n., E. utowaensis sp. n., E. waigeoensis sp. n., E. weylandensis sp. n., and E. wondiwoiensis sp. n. The lectotype of Copelatus politus Sharp, 1882 is designated. A checklist and identification key to all species of the group are provided and important diagnostic characters (habitus, color, male antennae and protarsomeres 4-5, median lobes and parameres) are illustrated. Data on the distribution and habitat requirements are given. Representatives of the E. ekari-group are so far mostly known from lowland to lower montane habitats of the northern and central parts of New Guinea, the group is less diverse in higher altitudes.
