TYPE SPECIES: Leioproctus (Leioproctus) macmillani Houston, 1991 .

DIAGNOSIS: This genus corresponds to Houston’s (1991) macmillani species group, fully characterized by that author. Particularly noteworthy traits include: frons rugulose; malar space much greater than basal mandibular width; flagellomeres II–X of male with cup-shaped, ventral, prong, flagellomeres I and XI with simple ventral lobe; probasitarsus of female with spines ventrally and long, curved bristles dorsally; male sternum VII with two apical lobes.

ETYMOLOGY: The new genus-group name is a combination of the Ancient Greek rhámphos (ῥᾰ́μφος, meaning, “beak”) and kollitís (κολλητής, meaning, “gluer” or “one who glues"). The gender of the name is masculine.
