(Fig. 44) Synaptopsyche nikalandugola SCHMID 1958: 114-115 . Holotype : Sri Lanka : Deniyaya , 5 February 1954 (Schmid) (not examined). Antennae 1.5 times length of forewing. In forewing crossveins Cu1-Cu2 and M3+4-Cu1 touching. In hindwing veins M and Cu1 almost touching; fork 1 present. Spur formula 044. This species is closest to P. czekanovskii , having the same upwardly directed hook formation, but the hooks are longer and the tenth tergum narrow with no lateral bulges. The ventral keel on the phallotheca is well developed. Although no type material was examined, this species is easily recognised from the description, and is the only species in Sri Lanka . Dr O.S. Flint ( NMNH ) kindly sent us specimens for examination .
