Type species: Platyplectrus natadae (Ferrière) . Autoplectrus Gadd, 1945: 331–337 . Type species: Autoplectrus taprobanes Gadd by monotypy. Synonymized by Bouček, 1988: 634 . Diagnosis. Propodeum not areolate, with one strong median carina; scutellum with sublateral grooves straight, or curved inwards sub-basally, or curved inwards to meet with each other; notauli distinct and complete, reaching scuto-scutellar suture. Hind legs always with two long tibial spurs, the longest spur reaching the halfway point of the second tarsal segment. Identification . Ferrière (1941) published a key to African species of Platyplectrus and Euplectromorpha (mostly synonymized with genus Platyplectrus ). Keys are also available to the 8 species of Platyplectrus species of Sri Lanka (Wijesekara &Schauff 1994), 13 species in China ( Zhu and Huang 2004 ), and 16 species in India ( Narendran 2011 ).
