Idioporidae new status

Idioporini LaSalle, Polaszek & Noyes, 1997. Type genus: Idioporus LaSalle & Polaszek, 1997.

Diagnosis.

Antenna with 9 flagellomeres, including 4 distinct clavomeres (Fig. 25 ). Clypeus with transverse subapical groove. Labrum hidden behind clypeus, flexible, subrectangular, with marginal setae in a row. Mandibles with 2 teeth. Subforaminal bridge with postgena separated by lower tentorial bridge. Mesopleural area without an expanded acropleuron; mesepimeron not extending over anterior margin of metapleuron (Fig. 26 ). All legs with 4 tarsomeres; protibial spur stout and slightly curved; basitarsal comb longitudinal (Fig. 27 ).

Discussion.

Idioporus affinis LaSalle & Polaszek is a highly distinctive species in Chalcidoidea (LaSalle et al. 1997) that has been problematic in placement regardless of whether using morphology or molecules. Relative to most other families discussed here, it is distinct in tarsomere count; only Zebe La Salle ( Pirenidae ) has four tarsomeres, but Zebe differs in having most funiculars greatly reduced. Idioporus differs from other taxa with 4-segmented tarsi on all legs, such as Eulophidae and Calesidae , and in having a stout and slightly curved protibial spur.
