Lispe surda Curran, 1937 ( Curran 1937; Paterson 1953: figs 14, 15; Vikhrev 2016)

Distribution. Described from South Africa, Bloemfontein (29.1 ° S 26.2 ° E, 1400 m asl).

Remarks. No material examined. To make the key below as reliable as possible I included in it only personally examined species. I trust Paterson (1953) publication but the information given there is scarce. That is why I placed this species in the Addendum. L. surda runs in my key to couplet 30. Male L. surda differs from males of L. ambigua and L. biseta by the absence of an anteriorly directed projection anterior part of sternite 4. Male cercal plate— Paterson (1953: fig. 15) or Vikhrev (2016: fig. 5). Body length: 7 mm (♂) or 7–7.5 mm (♀) and in female f2 without strong median av as in L. biseta . t2 with ad as in L. ambigua .
