DESCRIPTION (♀ 3): HEAD. Head in dorsal view slightly elongate, subangular, frons armed, with several sharp points; antennal shelf distinctly projecting, temple distinctly longer than eye; antennal shelf in lateral view distinctly prominent; torulus in level of lower half of eye; eye relatively small, subcircular, shorter than postgena, only slightly larger than malar space, posterior margin of eye rounded, ommatidia rather large and slightly convex; oral carina minute; postgenal cushion present; occipital flange minute; mandible bidentate, distinctly projecting, hypognathous, mandibular condyle with distinct raised rim; clypeus strongly convex; hypostomal bridge well developed, palpal formula 4–2; female antenna 11­segmented, with abrupt 3­segmented clava, A1 elongate cylindrical, not armed apically; male antenna 13­ segmented, slightly subclavate, with antennomeres gradually incrassated toward apex, A2 unusually large, A5–A12 transverse, almost beadlike, with abundant scattered pilosity, A13 largest, A4 curved, sexually modified, antennomeres without specialized brushes. MESOSOMA. Pronotum in dorsal view weakly developed, pronotal shoulders not developed, sides of pronotum rather flat, epomium absent, pronotal cushions strongly developed; mesoscutum as long as wide, only slightly convex, with weak declivities in notaular region, notaulus not clearly developed; anterior scutellar pit rather shallow, subrectangular, shorter than scutellar disc, scutellar disc subcircular, slightly convex, without median keel, posterior margin of axilla rounded, axillar depression minute, with fine pilosity, median oblique line of mesopleuron weakly indicated, sternaulus not present; dorsellum weakly developed, with three indistinct keels; metapleuron densely hairy; propodeum rather short, with distinct median keel, plica well developed, area between plicae and keel almost glabrous, posterior margin of propodeum arcuate; wings relatively short, with long marginal cilia; submarginal vein distinctly remote from margin, marginal and stigmal vein subtriangular, venation distinctly exceeding basal third of wing length, basal vein not developed; hind wing with submarginal vein weakly developed; legs relatively short, femora and tibia clavate distally, tarsi not compressed; apex of foretibia dorsally without spine. METASOMA. Petiole only slightly elongate, cylindrical, with dense fine pilosity; metasoma past petiole, elongate, slightly convex dorsally, anterior margin of syntergite straight or weakly excised medially; S2 with two hairy depressions anterolaterally; apex of metasoma in female only shortly pointed.

RECOGNITION AND RELATIONSHIPS: Mitropria is an intermediate genus between Basalys and Doliopria ; with the former it shares type of female clava, structure of head and mesosoma; with the latter the absence of basal vein as well as 11­segmented female antenna. However the structure of male antenna is peculiar to Mitropria . We prefer to rec­ ognize at this moment Mitropria as an independent genus.

DISTRIBUTION: Mitropria . coronata Ogloblin was described from Argentina. We examined the type material of the above species, as well as an undescribed species from Brazil.

BIOLOGY: Unknown.

Streptopria Maneval, 1939: 168 . Synonymized by Masner and Sundholm 1959: 161–168.

DIAGNOSIS (♀ 3): Small­sized individuals (1–1.5 mm), body generally elongate, body color from dark brown (mostly Nearctic species) to light brown or reddish (mostly Neotropical species), with head always darkest, body smooth and shining, head and mesosoma with scattered semierect hairs, body with massive hairy cushions, specialized dense pilosity, and some foamy structures; female antenna 13­segmented, abruptly clavate (1­segmented), with A13 remarkably enlarged; male antenna 14­segmented, with A4 not sexually modified; cervix of pronotum densely hairy, massive pronotal and propleural cushions confluent into complete hairy collar ventrally and dorsally; anterior scutellar pit not developed; metapleuron densely covered with appressed pilosity, pilosity continuing on metasternum, completely surrounding hind coxae; petiole entirely covered by dense specialized pilosity of different types; S2 with large and massive anterior cushion of specialized pilosity.

DESCRIPTION (♀ 3): HEAD. Head in dorsal view subglobular, frons unarmed, antennal shelf relatively large, not margined posteriorly; head in lateral view with antennal shelf considerably projecting, level of torulus in upper half of eye; eye of various sizes, subequal to or larger than malar space, posterior orbit of eye not sinuate; ommatidia rather small, not convex; oral carina almost absent; postgenal cushion massive, not contiguous either dorsally or ventrally; occipital flange moderately developed; mandible bidentate; hypostomal bridge well developed; palpi long and slender, palpal formula 5–2; female antenna 13­segmented, abruptly clavate (1­ segmented), with A13 remarkably enlarged, ovoid, without pit ventrally, A5–A10 minute, A1 long, cylindrical, unarmed apically; male antenna 14­segmented, antennomeres cylindrical, moderately to strongly elongate, with moderate to long scattered hairs, A4 not sexually modified, A3 subequal in length to oth­ er segments, distinctly shorter than A1, A1 long, cylindrical, unarmed apically, special brushes on A7 to A12 not developed. ME­ SOSOMA. Pronotum in dorsal view moderately developed, pronotal shoulders not developed, epomium absent, cervix densely hairy, massive pronotal and propleural cushions confluent into complete hairy collar ventrally and dorsally; mesoscutum slightly elongate, only moderately convex to nearly flat, without lines or depressions; anterior scutellar pit not developed, rarely replaced by very shallow concavity; axilla fused with scutellar pit area and scutellar disc in one plate; scutellar disc with sides slightly converging posteriorly, in one undescribed species with moderated longitudinal keel; posterior margin of axilla rounded, axillar depression very small, hairy; mesopleuron almost flat, glabrous, oblique subhorizontal line weakly developed or absent, sternaulus not developed, ventral side of mesopleuron (between fore and middle coxae) with fine pilosity; dorsellum weakly developed, with indistinct keels, metapleuron densely covered with appressed pilosity; pilosity continuing on metasternum completely surrounding hind coxae; propodeum elongate, with distinct median keel, keel usually pointed anteriorly or lamellate, keel usually glabrous, adjacent plical area also often glabrous, remaining propodeum densely hairy, plica not developed, posterior margin of propodeum moderately excavate; forewing rather elongate and narrow, anterior margin sometimes slightly sinuate, apex often truncate to emarginate, marginal cilia remarkably long, including on anterior margin past marginal vein, microtrichia on disc relatively strong; submarginal vein usually straight, strongly approximated to foremargin, long, distinctly exceeding basal third of wing length, marginal vein long, keel shape, stigmal vein absent, anterior margin of basal vein not de­ veloped but wing often with transverse dark­ er strip below apex of marginal vein; hind wing with distinctly sclerotized submarginal vein; wings shortened or absent in some undescribed species; legs long and slender, with femora and tibia distinctly clavate in distal half; apex of foretibia with minute spine dorsally, tarsi long and slender, not compressed. METASOMA. Petiole distinctly elongate, cylindrical, entirely covered by dense specialized pilosity of different types, both dorsally and ventrally, pilosity posterodorsally partly overlapping anterior margin of syntergite; metasoma past petiole distinctly elongate, only slightly convex dorsally, anterior margin of syntergite straight and generally covered with narrow band of modified pilosity, pilosity continuing ventrally forming uninterrupted hairy ring; posterior part of metasoma characteristically subangular with short, broadly triangular point in female; S2 anteriorly with large and massive cushion of specialized pilosity.

RECOGNITION AND RELATIONSHIPS: The abundance and different types of pilosity make Monelata unique in the Diapriinae . The females are easily recognized because of the unique structure of the antenna. The males, however, were described as a different genus ( Maneval, 1939) and only recently properly distinguished from some males of Trichopria (= Phaenopria ) (Pschorn­Walcher, 1956); the principal difference is in the structure of A4 and pubescence of propodeum, petiole, and S2.

DISTRIBUTION: The genus is found both in North and South America (except in Chile), with many species still undescribed.

BIOLOGY: Host unknown. Members were once observed on stable manure (Pschorn­ Walcher, 1956).
