Dozodipara Desjardins , New Genus

( Fig. 65 )

Type Species: Dozodipara insularis Desjardins , New Species

Diagnosis: Dozodipara is most easily distinguished from most diparines by a combination of two features. First, the toruli appear to lie on a shelf, and a sharp angle of 90° separates the upper and lower face (as in Fig. 8 ). The only other diparines with this feature are Conophorisca , and, to a lesser extent, Cerodipara , which has an upper and lower face separated by a rounded angle of 90°. Second, the propodeum of Dozodipara is very steep, being higher than long ( Fig. 65 ). While Cerodipara shares this propodeal shape, this feature is otherwise unique within Diparinae , all other genera having propodea at least 1.5X as long as high. Dozodipara can be separated from Cerodipara by having uniformally convex inner eye margins and lacking a vertical carinate ridge running from the interantennal area to the ventral clypeal margin, whereas Cerodipara has ventrally diverging inner eye margins and a vertical carinate ridge running from the interantennal area to the ventral clypeal margin. Addtionally, Dozodipara has a scutellar conformation unique within Diparinae : broad, slightly convex, and with the posterior margin in the same horizontal plane of the body as the anterior margin.

Description: Female. Head: Occipital margin rounded; occipital carina present; upper face without strong, transversely carinate sculpture; eyes not posteriorly extended beyond occipital margin; inner eye margins uniformly convex; eyes bare; scrobe present and scrobal channel slightly triangular dorsal to toruli; dorsal margin of scrobe rounded; toruli on shelf, sharp angle of ~90° between upper and lower face; antennae symmetrically clavate; antennal formula 11173; pedicel, first funicular segment, second funicular segment subequal in length; claval apex without thick tuft of micropilosity; apical clypeal margin symmetrically bilobed; malar groove present; strong, dark bristles on vertex absent. Mesosoma: dorsum of mesosoma without strong, dark bristles; pronotum short, collar-like; notauli strongly arched along entire length (appearing semi-circular) and meeting posterior scutal margin at scutoscutellar suture; lateral lobes of scutum similar in color to remainder of scutum; posterior scutal margin without setose groove; scutellum large, slightly convex with apex near posterior margin, not descending posteriorly; axillae convex, reduced; posterior notal wing process present, pointed; frenal sulcus absent; metanotum present as narrow, sculptured band; propodeum at least 1.5X higher than long; propodeum with dorso-ventrally flattened projection near anterior margin; plicae absent; suture between postspiracular area and metapleuron diagonal; propodeal foramen circular, open in one plane; longitudinal invagination of pronotum, mesepimeron and metapleuron absent; prepectus reduced, not reaching tegula; tegula normal, flap-like; axillary wing sclerite not visible; acropleuron slightly convex, partially expanded along dorsal length of mesopleuron; mesopleuron with smooth and sculptured regions posteriorly; metacoxa posteriorly convex, with transverse striations; metacoxa posteriorly without thick vertical brush of setae; 1 metatibial spur, <1.5X width of tibia at point of insertion. Metasoma: Petiole cylindrical, without setae, broader than long; GT1 expanded, covering at least half of metasoma length; GT1 rounded lateral to petiole insertion; cercal setae elongate; cercal brush present. Male: Unknown.

Discussion: In analyses excluding bristle characters, Dozodipara is resolved as basal to the clade inclusive of Boeria , Cerodipara , and the most derived diparines (see the generic entry for Boeria for a more detailed discussion). The clade of diparines inclusive of these taxa is defined by 2 synapomorphies: a reduced prepectus and strongly arched notauli which meet the posterior scutal margin at the scutoscutellar suture.

Etymology: Dozo- from the bulldozer-like shape of the head (due to the torular shelf) and compact body. -dipara to ally the genus with Diparinae .
