SI: Figure 26a–d. Forewing length: male 22–26.5 mm (mean ( n = 7) 24.70 mm , SD = 1.180); female 23– 26.5 mm (mean ( n = 7) 24.44 mm , SD = 0.802). Records. Mufindi, West Usambara and Northern Highlands, in open grasslands and bush at 1500–2200 m elevation ( Kielland 1990 , p.63). Based on 14 specimens collected by Johnston, this butterfly was recorded from “Kilima-njaro, wooded, rocky, and cultivated ground, grassy downs, at 4000 to 5,500 feet , July and August” ( Godman 1885 , p.539, as Pieris hellica ), noting that it differed slightly in coloration from “the examples in our own collection”. Two years later Crowley described Synchloe johnstonii [sic] based on material from the same source. A pair in OUMNH were collected on the slopes of Kilimanjaro in September 1905 , at about 5000 ft , by K. St Aubyn Rogers. Aurivillius (1910a, p.11), based on the fieldwork of Sjöstedt, recorded this butterfly from Kibongoto, flying up to at least 1200 m . This species, not encountered by Liseki (2009) at 2000 m or above, is included here as a member of the lower slopes fauna, flying below the main forest zone at c. 1200–1800 m . Beyond Tanzania , subspecies johnstonii occurs in grassy areas in the highlands of Uganda , Kenya , Rwanda , Burundi and eastern DRC ( Kivu and Ituri). The nominate race flies from eastern Zimbabwe south to Cape Province ( Ackery et al. 1995 , p.210). There is slight sexual dimorphism and minor variation in this species, but in appearance compared with most other regional Pierinae this is a constant and distinctive butterfly.
