Remarks

• Systematics: Slide-mounted adult female with: enlarged setae slender, elongate, apices acute, present on body margin only, other dorsal setae hair like, slightly smaller than marginal enlarged setae, 3 lateral setae on margin of each abdominal segment; anal lobes slender, with conspicuous medial teeth; sclerotized plate present on dorsum anterior of anal ring; macrotubular ducts and multilocular pores restricted to body margin on dorsum (Yang, 1982). We were unable to detect any differences between this species and Gossypariella phyllanthi. Tang & Hao (1995) suggest that G. siamensis differs from G. phyllanthi by lacking dorsal multilocular pores, but the illustration of Yang (1982) shows a few multilocular pores on the margin of the dorsum on the abdomen.
• Structure: Dried adult female blackish brown, body subcircular (Takahashi, 1942b).
• Biology: Bisexual reproduction with a Lecanoid heterochromatinization in male embryos. Complete ovoviviparity. Female reproductive system is similar with that in the previous species, but accessory glands are located in the middle part of the common oviduct (Gavrilov-Zimin, 2020)
• General Remarks: Detailed description by Takahashi (1942b).
