Table 1. Morphological features that can be used to separate S. kunmingensis sp. nov. and S. coffeae. VTDs = ventral tubular ducts. Morphological featuresS. kunmingensis sp. nov.S. coffeaeType I VTDsPresent submarginally in a broad band around body, mediolaterally on posterior abdominal segmentsAbsentType II VTDsPresent submarginally and mediolaterally on posterior abdominal segments, sparse, few and discrete between 2 spiracular pore bands and headPresent on inner submarginal area around body and medial thorax (Tang 1991; Choi and Lee 2017)Type III VTDsPresent submarginally and inner submarginally on posterior abdominal segments, rarely present on submarginal area of headPresent on outer submarginal area around body (Tang 1991; Choi and Lee 2017)Type IV VTDsAbsentPresent on medial submarginal area around body (Tang 1991; Choi and Lee 2017)Distribution of VTDsDistributed irregularly, type I and type II ventral tubular ducts mixed mediolaterally on posterior abdominal segments, and in a broad band around body, type III ducts mixed with them submarginally on posterior abdominal segmentsDistributed regularly (Tang 1991; Choi and Lee 2017)Dorsal setaeThick and long, 20.1-28.9 μm long including basal socket, 14.2-21.0 μm long without a basal socketRather short, 6.0-9.0 μm long (Choi and Lee 2017)

表1 可用于区分S. kunmingensis sp. nov.(昆明链霉菌新种)与S. coffeae(咖啡链霉菌)的形态特征。VTDs=腹管孔(ventral tubular ducts)。 I型腹管孔(Type I VTDs): S. kunmingensis sp. nov.(昆明链霉菌新种):在体周呈宽带状分布于亚缘区,后腹部节段的中外侧亦有分布; S. coffeae(咖啡链霉菌):无该类结构。 II型腹管孔(Type II VTDs): S. kunmingensis sp. nov.(昆明链霉菌新种):分布于后腹部节段的亚缘区与中外侧,在2条气门孔带与头部之间呈稀疏、少量且分散的状态; S. coffeae(咖啡链霉菌):分布于体周内侧亚缘区与胸部内侧(Tang 1991; Choi and Lee 2017)。 III型腹管孔(Type III VTDs): S. kunmingensis sp. nov.(昆明链霉菌新种):分布于后腹部节段的亚缘区与内侧亚缘区,头部亚缘区极少出现; S. coffeae(咖啡链霉菌):分布于体周外侧亚缘区(Tang 1991; Choi and Lee 2017)。 IV型腹管孔(Type IV VTDs): S. kunmingensis sp. nov.(昆明链霉菌新种):无该类结构; S. coffeae(咖啡链霉菌):分布于体周内侧亚缘区(Tang 1991; Choi and Lee 2017)。 腹管孔分布(Distribution of VTDs): S. kunmingensis sp. nov.(昆明链霉菌新种):分布不规则,I型与II型腹管孔在后腹部节段的中外侧以及体周宽带中混合存在,III型管孔与它们一同分布于后腹部节段的亚缘区; S. coffeae(咖啡链霉菌):分布规整(Tang 1991; Choi and Lee 2017)。 背刚毛(Dorsal setae): S. kunmingensis sp. nov.(昆明链霉菌新种):粗壮修长,含刚毛基窝时长20.1~28.9 μm,不含刚毛基窝时长14.2~21.0 μm; S. coffeae(咖啡链霉菌):相对短缩,长6.0~9.0 μm(Choi and Lee 2017)。
