Cleared to taxi to [Runway] 24L via E. Captain taxiing; I'm finishing the Before Takeoff checklist as we come to the end of [Runway] 24L. After sitting at the hold short line for a minute or so Tower questioned where we are. I responded holding short of [Runway] 24L; he sounds irritated and says there is a sign that we are supposed to hold short of when cleared to [Runway] 24L. Neither the Captain nor I were familiar with this procedure or had seen the sign. There is no note or mention of it anywhere on the charts or anywhere that we could find later and Ground Control made no mention of it.Noting such a hold line on the airport diagram would be helpful. There is a similar hold line for [Runway] 25R that is noted on the chart. Why not the one on [Runway] 24L? Why doesn't Ground Control give specific hold short instructions in taxi clearance?
An A319 taxied to the end of LAX Taxiway E and was admonished for failing to hold short at the specified hold short sign but the crew did not see a sign nor is a hold short note printed on the airport diagram as it is for Runway 25R.
