Key to the genera of the family Haaseidae 1. Coxal processes of the posterior gonopods surpassing telopodites in height............................. Romanosoma - Coxal processes of the posterior gonopods lower than the telopodites............................................ 2 2. Coxal processes of the posterior gonopods with two or three branches....................................... Haasea - Coxal processes of the posterior gonopods unipartite......................................................... 3 3. Medial sternal process of the anterior gonopods significantly exceeds half the height of the angiocoxites..... Hylebainosoma - Medial sternal process of the anterior gonopods shorter than half the height of angiocoxties.......................... 4 4. Coxal processes of the posterior gonopods robust and wide. Leg-pair 3 in females reduced to one podomere............................................................................................... Maurieseuma gen. nov. - Coxal processes of the posterior gonopods slender distally. Leg-pair 3 in females normal.................. Xylophageuma
