13. Neolophonotus variabilis Londt, 1986

Remarks.

This somewhat variable species, a member of the suillus species group, was described using many specimens collected mainly in KwaZulu-Natal, but also recorded from various localities in the Eastern and Western Cape provinces ( Londt 1986), most being at relatively high altitudes. While not previously recorded from Hilton or Pietermaritzburg, the closest recorded localities are Bulwer (ca. 29°48'27"S, 29°45'36"E) and New Hanover (ca. 29°21'08"S, 30°31'26"E).

Single specimens were collected at Jacana in weeks 36 and 39, fair numbers were then encountered in weeks 41-45 and a single specimen was collected in week 46. Although the species was not encountered in weeks 47-51, a single specimen was netted in week 52. Although the flight period spanned some 17 weeks (from week 36 to 52), the species appeared to be most active in late spring between weeks 41-45. All encountered individuals were found in the lower field.

This species was usually observed resting on the ground or on vegetation close to the ground and is considered belonging to Londt’s (1994) ecological category 1c (open ground). None were found with prey.
