Comparative diagnosis

Apsilota leptoarticulata sp. nov. is similar to A. deserta Papp, 1967 ( Fischer 1974a) , A. makita Papp, 2008 ( Papp 2008) , and A. ventasa Belokobylskij, 2007 . The new species differs from A. deserta in having the first flagellar segment 4.5 times as long as its maximum width (6.0 times in A. deserta ) , hind femur 4.5 times as long as its maximum width (3.6 times in A. deserta ) , precoxal suture present, not reaching anterior or posterior margins of mesopleuron (reaching anterior margin in A. deserta ) , and vein r2 (3- SR) 2.8 times as long as vein cuqu1 (2- SR) (1.5 times in A. deserta ) . On the other hand, A. leptoarticulata sp. nov. differs from A. makita (see Papp 2008) in having the first flagellar segment 4.5 times as long as its maximum width (4.0 times in A. makita ) , eye in lateral view 1.1 times as wide as temple medially (0.9 times in A. makita ) , hind femur 4.5 times as long as its maximum width (3.8 times in A. makita ) , and vein r2 (3- SR) 2.8 times as long as vein cuqu1 (2- SR) (1.7 times in A. makita ) . Finally, the new species differs from A. ventasa in having the first flagellar segment 4.5 times as long as its maximum width (3.7–3.8 times in A. ventasa ) , first metasomal tergite 2.0 times as long as its apical width (2.3 times in A. ventasa ) , eye in lateral view 1.1 times as wide as temple medially (0.9 times in A. ventasa ) , face 1.5 times as wide as high (1.8 times in A. ventasa ) , precoxal suture not reaching anterior margin of mesopleuron (reaching in A. ventasa ) , and vein r2 (3- SR) 2.8 times as long as vein cuqu1 (2- SR) (1.7 times in A. ventasa ) .
