The Southeast Asian soft scale insects (Hemiptera: Coccomorpha: Coccidae) associated with ants of the Crematogaster borneensis-group (Hymenoptera: Formicidae) and living in the hollow stems of Macaranga plants (Euphorbiaceae) are revised taxonomically. Ten species of the genus Coccus L. are recognised: seven were described previously and three new species are described herein. The species are: Coccus caviramicolus Morrison, C. circularis Morrison, C. heckrothi Gullan Kondo sp. n., C. lambirensis Gullan Kondo sp. n., C. macarangicolus Takahashi, C. macarangae Morrison, C. penangensis Morrison, C. pseudotumuliferus Gullan Kondo sp. n., C. secretus Morrison and C. tumuliferus Morrison. All of these species are described or redescribed and newly illustrated based on the adult females, and a key to distinguish the species is provided. We designate a lectotype for C. macarangicolus. The first-instar nymphs of all species are morphologically extremely similar and therefore only the first-instar nymph of C. macarangae is described and illustrated. Seven of these species currently are known only from Macaranga, but C. macarangae, C. secretus and perhaps C. pseudotumuliferus have been recorded from the hollow stems of several other ant-plants and a few non-myrmecophytes. The Coccus species from Macaranga are closely related to C. hesperidum L., the type species of the genus, and therefore are retained in the genus Coccus even though the adult females exhibit a few morphological differences from C. hesperidum. The species of Coccus from Macaranga appear to be parthenogenetic because no male nymphs or adults have been found, despite extensive collecting.
对与婆罗洲举腹蚁属（膜翅目：蚁科）蚂蚁相关、生活在血桐属植物（大戟科）中空茎干中的东南亚软蚧（半翅目：蚧亚目：蚧科）进行了分类修订。确认了绵蚧属的10个物种：7个为先前已描述的物种，本文描述了3个新物种。这些物种分别是：圆腔绵蚧Morrison、圆形绵蚧Morrison、赫氏绵蚧Gullan & Kondo新种、兰比尔绵蚧Gullan & Kondo新种、血桐绵蚧Takahashi、血桐绵蚧Morrison、槟城绵蚧Morrison、拟瘤绵蚧Gullan & Kondo新种、隐秘绵蚧Morrison和瘤绵蚧Morrison。所有这些物种均基于成年雌虫进行了描述或重新描述，并给出了新的图示，还提供了区分这些物种的检索表。我们指定了血桐绵蚧的选模标本。所有物种的一龄若虫在形态上极为相似，因此仅描述并图示了血桐绵蚧的一龄若虫。目前已知其中7个物种仅存在于血桐属植物中，但血桐绵蚧、隐秘绵蚧以及可能的拟瘤绵蚧已在其他几种蚁栖植物和少数非蚁栖植物的中空茎干中被记录到。来自血桐属植物的绵蚧物种与该属的模式种柑橘绵蚧Coccus hesperidum L.密切相关，因此尽管成年雌虫与柑橘绵蚧存在一些形态差异，但仍保留在绵蚧属中。尽管进行了广泛采集，但尚未发现雄性若虫或成虫，因此来自血桐属植物的绵蚧物种似乎为孤雌生殖。
