Bassocaeciliini new tribe

Diagnosis. With the characters of the subfamily ( Mockford , 2000) plus the following: clypeal shelf broad; labral stylets present; lacinial tip broad, denticulate; body dark; lateral apophyses of subgenital plate absent; ventral abdominal vesicles single or absent; wings very elongated, narrow, without pattern; papillae on male epiproct and paraproct absent.

Remarks. In what he described as a progress report, Mockford (2000) outlined a combination of characters associated with the five new tribes of the subfamily Caeciliusinae . The distribution of the distal inner labral sensilla excludes one tribe (Caeciliusini) from the Australian fauna, as only labral sensilla type 2 ( Mockford 2000: 393, fig. 4) are found in all Australian genera of this subfamily. The genera represent each of the four remaining tribes. A broad clypeal shelf is found only in Coryphacini , but in genera of that tribe the lacinial tip is slender, its shape bicuspid, bilobed or rounded. An absence of both ventral abdominal vesicles and papillae on the male epiproct are characers of Epicaeciliini . However, genera of this tribe possess a clypeal shelf that is narrow or absent, and a lacinial tip that is very wide. Genera within Kodamaiini (not known from Tasmania) and Maoripsocini lack a broad clypeal shelf, and possess two abdominal vesicles. The lacinial tip in the former tribe is of medium width, with one or two shallow denticles between cusps, while in the latter tribe it is broad and denticulate. The above combination of characters is not found in any tribes within Caeciliusinae , and therefore Bassocaeciliini is established.
