Fractipons Townes, 1970

Type species:

Fractipons cincticornis Townes, 1970. Memoirs of the American Entomological Institute 12: 14. Holotype, ♀.

Diagnosis.

Mesopleural impression below speculum consisting of an isolated pit which is some distance in front of mesopleural suture. Occipital carina reaching base of mandible. Median lobe of mesoscutum without median longitudinal groove. Posterior transverse carina of the mesosternum interrupted in front of mid coxae. Apical transverse carina of propodeum strong, abruptly interrupted medially and forming lateral flat crests (Fig. 1).

Description.

Body moderately slender, 4.8-7.1 mm, mostly smooth and polished. Head transverse. Flagellomeres of female conspicuously thickened from third flagellomere, slightly thin towards apex, from tenth to penultimate flattened below; in this flat area with conspicuous setiferous sensillae (Fig. 2). Lower face finely and densely punctate, with small central prominence. Clypeus rather wide, apical margin sharp, straight or slightly arcuate. Malar space forming wide and deep granulate area (Figs 16, 18, 20). Mandible moderately tapered to apex, lower tooth shorter than upper tooth. Maxillary palpus reaching to ventral part of epicnemial carina. Occipital carina joining base of mandible, nearly angular on mid-dorsal part. Pronotal transverse groove without median longitudinal ridge. Epomia absent. Median lobe of mesoscutum without median longitudinal groove. Notauli rather weak, about 0.3-0.7 as long as mesoscutum. Precutellar groove without traces of longitudinal carinae. Scutellum moderately convex, polished and smooth or very sparsely punctate, lateral carinae strong, extending about 0.8-0.9 its length. Mesopleuron completely smooth and polished.Mesopleural impression below speculum consisting of an isolated pit some distance in front of mesopleural suture. Sternaulus weak on anterior 0.3-0.5, nearly absent posteriorly. Epicnemial carina reaching 0.7-0.9 × height of mesopleuron, at upper margin weak or absent. Posterior transverse carina of mesosternum widely interrupted in front of each mid coxa, laterally elevated forming strong flat crest. Areolet open. Ramulus absent. Vein 2 m–cu weakly inclivous, with two bullae. Vein cu-a opposite Rs+M or slightly basal. Hind wing with M+Cu moderately curved at apical 0.5. Abscissa of M+Cu between M and Cu1 longer than cu-a, strongly inclivous, cu-a reclivous. Propodeum with anterior transverse carina strong and complete. Apical transverse carina of propodeum strong and abruptly interrupted medially, forming lateral flat crests (Fig. 1). Lateral longitudinal carina of propodeum only present apically, distad of crests. Lateromedian carina partially present in area basalis. Area superomedia absent. Pleural carina rounded and strong. Submetapleural carina forming anterior flat crest. Juxtacoxal carina absent. Propodeal spiracle elongate. First metasomal tergite smooth and polished, sometimes with sparse setiferous punctures, dorsally, laterally, upper face weakly convex, median dorsal and lateral carinae absent. Spiracle at the apical 0.46. Postpetiole about 0.7-0.8 times as long as maximum width (measured dorsally). Tergites 2-7 smooth and shiny with fine setiferous punctures. Epipleura of tergites 2 and 3 separated by crease, of tergite 4 not separated. Gastrocoelus wider than long, thyridium finely granulate. Ovipositor straight, with nodus, upper valve with five dorsal teeth, lower valve with three oblique notches and 4-5 small complete and transverse apical teeth (Fig. 3).
