Remarks

• Systematics: Williams (2004a) elucidated the intraspecific variation of taxonomic characters, and provided two diagramatic illustrations of the adult female. Danzig & Gavrilov-Zimin (2015) transferred this species to Paraputo because it has six setae in the anal apparatus. However, as discussed by Williams (2004) and Zhang & Wu (2017), the number of anal ring setae is not a robust genus-level character, especially as the number of setae can vary between the two sides of the anal ring. Furthermore, in both genera there are 6 basic anal ring setae and, if more are present, the extra setae are usually short and slender and variable in position. Adult females of Formicococcus and Paraputo are morphologically similar and these genera clearly are related, but have been distinguished by the presence (Formicococcus) or absence (Paraputo) of the anal lobe bar (Williams 2004; Zhang & Wu 2017). Formicococcus robustus and the other seven species of this genus known from India each have anal lobe bars. (Joshi, et al., 2020)
• Structure: Slide-mounted adult female broadly oval, membranous. Anal lobe with anal lobe bar either partial (present forwards from bar seta) or complete. Antennae each with 8 segments. Legs well developed. Hind leg with translucent pores on ventral and dorsal surfaces of coxa and on dorsal surface of tibia; tarsal digitules pointed at tip and longer than claw. (Moghaddam & Watson, 2022) Parida & Moharana (1982) and Moharana (1990) reported chromosome number 2n=10 in India.
• General Remarks: Description and illustration of the adult female by Ezzat & McConnell (1956), Ali (1968a), Avasthi & Shafee (1986a, 1987), Ghosh & Ghose (1988LC) and by Williams (2004a).
