After landing on Runway 04 in night VFR conditions at LGA with an MEL for Taxi light inop; we were cleared to eventually taxi via Bravo to Lane 9 to enter ramp. As we approached Lane 8; there was an aircraft among a line of aircraft departing on [Runway] 31 with it's tail protruding onto Bravo enough to make us stop on Bravo. After a few minutes wait; the Captain decided he might be able to taxi around the tail of the aircraft by using part of Lima. After attempting to do this; we saw that there was not enough room to get back on to Bravo after the aircraft tail; and we were now forced to turn right at Lima on to the ramp. The Taxi light being inoperative; we could not see that in making this turn not only put us on to the ramp early; but it also forced us to taxi across the painted 'island' that physically exists; but is not depicted on the Jeppesen 10-9B chart. The combination of no Taxi light and an improperly marked reference chart; caused us to taxi over the painted 'island'; which after we had done so; was chastised for by the Ramp Controller as he also 'reminded' us that we had been cleared to enter at Lane 9 vice 8. Fortunately; the scolding was all we received and the rest of the taxiing went uneventfully.
Air carrier Non Flying First Officer reported a near taxiway incursion due to Jeppsen 10-9B chart not depicting the island at spot as is depicted on 10-9.
