 "Afraflacilla grayorum" Grays' stridulating jumping spider, found in northern Australian deserts, was named in honour of Michael and Greta Gray.The male palpal organ of many Australian "Afraflacilla" species has a large, circling embolus (inseminating sclerite) and retro-lateral tibial apophysis (side spike).Some undescribed Australian "Afraflacilla" species have greatly enlarged segments of the first pair of legs, and sometimes massive spurs coming from underneath the tibia and metatarsus (third and second last leg segments).
