Leioproctus (Leioproctus) obscurus (Smith, 1853)

Lamprocolletes obscurus *Smith 1853: 11 ; Dalla Torre, 1896: 48.

Paracolletes semilautus * Cockerell 1905c: 485 ; 1906: 29; 1934: 35. syn.n. Paracolletes hobartensis * Cockerell 1906: 23 , 29; 1934: 28. syn.n. Paracolletes obscurus (Smith) . Cockerell 1929d: 310; 1934: 31. Paracolletes stewarti *Rayment 1947: 102 . syn.n. Leioproctus hobartensis (Cockerell) . Michener, 1965: 51. Leioproctus obscurus (Smith) . Michener 1965: 51. Leioproctus semilautus (Cockerell) . Michener 1965: 52. Leioproctus stewarti (Rayment) . Michener 1965: 52. The holotypes of Paracolletes semilautus and Paracolletes stewarti , which are male, are the same as those males associated with Lamprocolletes obscurus by morphological similarity and coincident collection data. The holotypes of

Lamprocolletes obscurus and Paracolletes hobartensis , are female, and show no significant morphological differences.
