Genus group Entedononecremnus

Included genera. Entedononecremnus , Itahipeus , Sifraneurus .

Distribution

Neotropical and southern Nearctic regions: Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guyana, Honduras, Mexico, Peru, USA, Venezuela, the West Indies.

Hosts Whiteflies in the subfamily Aleurodicinae ( Hemiptera : Aleyrodidae ).

Diagnosis

Frontal and vertexal sutures absent (figure 29); malar sulcus present; eyes bare (figure 29); mid lobe of mesoscutum with numerous scattered setae, or with one to five pair; major part of axillae situated behind scuto-scutellar sulcus and separated from mesoscutum by a sulcus (figures 8, 31); scutellum not distinctly wider than long, with numerous scattered setae or with two to seven pair; submarginal vein with three to six setae on dorsal surface; with a ± distinct break between submarginal and marginal veins (figures 8, 119–121), or ± continuous (figure 9); posterolateral propodeum drawn out in a point (figure 31).

Monophyly

This restructured genus group (as compared to LaSalle and Schauff, 1994) is supported by the following apomorphies: frontal suture absent; eyes bare; submarginal vein with three to six setae on dorsal surface; posterolateral propodeum drawn out in a point. Some of these character states are also present in the other genus groups: frontal suture is absent in three genera in the Euderomphale group; eyes are bare in one genus in the Euderomphale group; submarginal vein with more than two setae in the entire Aleuroctonus group. The extended posterolateral part of propodeum is unique to the Entedononecremnus genus group.

Comments

Our interpretation of this genus group differs from that put forward by LaSalle and Schauff (1994). This deviating interpretation is due to the fact that two new genera have been added to the group. These new genera have enhanced the knowledge of the variation of certain character states, here regarded as valuable for the classification of this group. The main difference, apart from the inclusion of the new genera, is that we have moved the genera Aleuroctonus and Dasyomphale from this genus group, and created a new group for them, the Aleuroctonus genus group.
