Following the radial segment upward and towards the leading edge of the wing, one can see there are 4 consecutive forks.

Moveover, as pertains to the first couplet in the key to world genera of Chauliodinae...note that the posterior branch of the radial segment (i.e. R4+5) is forked distally in the forewing. (It can also be seen to be forked distally in the hindwing...see the 5th image of this series.)
