I'm going to do my best to keep this thread going so that we don't revert to 
political/religious flamewars.  wouldn't you all prefer an orchidaceous 
taxonomy flamewar?

Given all that, wouldn't you agree that having large, broadly defined genera is 
safer than smaller genera?  In the case at hand, if the data splitting the 
Mexican from the Brazilian laelias is robust, but the inter-relationships 
between the Brazilian species is more open to judgement calls, then lumping the 
Brazilians all into Sophronitis would help to create taxonomic stability.  That 
way, when new data is generated which calls into question the relationship 
between, say, Sophronitis coccinea and Sophronitis purpurata, phylogenetic 
trees can be drawn and papers published without mucking around with the 
taxonomy.  As van den Berg points out in his response, new data has already 
called into question the boundaries of the new Sophronitis and Hadrolaelia 
published by Chiron and Castro Neto.
