Remarks

• Systematics: The male of P. dilli is apterous and rather female-like and therefore lacks most of the sclerites typical of male Pseudococcidae. However, based on the morphology of the adult male, it is clearly a member of the Pseudococcidae and Williams (2002) and Hardy et al. (2008) placed Promyrmococcus within the subfamily Pseudococcinae, based mainly on adult female characters. (Hodgson, 2012)
• Structure: Adult male small, total body length about 1.3-1.5 mm; apterous. Antennae about half total body length, with long setae (probably fleshy setae, each 1.5-2.0 times longer than width of antennal segments); body with many hair-like setae, some on each segment extremely long, 450-770 ìm long; fleshy setae apparently absent on body. Trilocular pores absent; simple pores few. Head more or less without ridges or sclerites. Simple eyes (se) absent; ocelli (o) present. Mouthparts reduced and non-functional but present. Legs well developed, each with a 2-segmented tarsus (ta) and without tibial or tarsal spurs; tarsal digitules knobbed. Circulus often present between abdominal segments III and IV. Ostioles (os) present, both anteriorly and posteriorly, with strongly sclerotised margins. Glandular pouches absent but with a group of setae plus a few 5-locular pores in this position. Anus near apex of penial sheath, under abdominal segment IX. Ventrally, penial sheath (ps) with a pair of lobes medially. (Hodgson, 2012) The basic morphology of the prepupa and pupa of P. dilli is very similar to that of the adult male, except that they lack the genital structures, have (at most) 7-segmented antenna (9 segmented on the adult male) and their tarsi appear to be only one segmented. Reduced mouthparts lacking stylets are also present on the adult male. (Williams & Hodgson, 2013)
• Biology: Found in nest of Dolichoderus maschwitzi (Williams, 2002b).
