Identification: Thorax: Humeri orange/brown, this colour frequently extending down across the pleurae as far as the coxae. Mesonotum black with strong white dusting - thus always appearing as some shade of grey, the dusting may be very heavy. Pleurae also appearing grey due to dusting which is heavier than on the mesonotum. Head: Long palpi; frons completely orange with white dusted edges against the eyes and some darkening around the ocelli. Male: Pleural membrane white or gray. Paired pale outgrowths on sternites 3 & 4 (apices bent to point backwards) and on S5 (apex bent to point forwards). The entire complement of outgrowths are not always visible in photographs.
