RECOGNITION AND RELATIONSHIPS: Xenismarus is one of the most plesiomorphic genera of Spilomicrini as exemplified by its antennal formula (14–14). It is related to more plesiomorphic species of Entomacis (e.g., in Chile), and also to Poecilopsilus and Doddius , especially in the structure of toruli and shape of rim on A1. Xenismarus differs from all genera above by the antennal formula, furthermore, from Poecilopsilus by the reduced armature of the dorsellum, from Doddius by the nonstriate cheek, and from Entomacis by the broadly exposed labrum and conically pointed metasoma in the female.

DISTRIBUTION: We examined specimens of Xenismarus from the Valdivian forest of Chile and Argentina; one undescribed species is known to us from the Juan Fernandez Islands ( Chile).

BIOLOGY: Unknown.

REMARKS: The tribe Diapriini is interpreted here in the classical sense. At present, we classify 33 genera, represented in the New World: Acanthopria Ashmead ; Apopria , new genus; Asolenopsia Kieffer ; Auxopaedeutes Brues ; Avoca , new genus; Basalys Westwood ; Bruesopria Wing ; Cruzium , new genus; Diapria Latreille Doliopria Kieffer ; Ecitovagus Masner ; Eladio , new genus; Hansona , new genus; Labidopria Wasmann ; Leucopria , new genus; Megaplastopria Ashmead ; Mimopria Holmgren ; Mimopriella , new genus; Mitropria Ogloblin ; Monelata Foerster ; Myrmecopria Ashmead ; Neivapria Borgmeier ; Notoxoides Ashmead ; Omopria , new genus; Philolestoides Ferrière ; Platymiscus Westwood; Psychopria , new genus; Szelenyiopria Fabritius ; Szelenyisca Masner ; Townesella Huggert and Masner ; Trichopria Ashmead ; Turripria , new genus; and Xanthopria Brues. This is probably the most speciose, diverse, and most apomorphic tribe of the subfamily Diapriinae . Diapriini is the only tribe that includes all true symphilic genera, some of them considerably adapted morphologically to life with ants; these adaptations include far­reaching mimicry with the host ants including the type of sculpture, pilosity, color, behavior, and biology. The biological ground plan is primary parasitism (solitary or gregarious) of various Diptera ; several species were reared from coleopterous hosts, members associated with ants are known or assumed to parasitize ant larvae; some species are aquatic.

RECOGNITION AND RELATIONSHIPS: Acanthopria is one of the largest genera of Neotropical Diapriinae . Although only few species were described, we estimate the numbers to reach hundreds. Originally Acanthopria in females was recognized on the armed scutellum ( Ashmead, 1893; Kieffer, 1916). The polytypic nature of Acanthopria in females is exemplified by a number of natural species groups, showing great diversity of character states. After examination of a large amount of material consisting of thousands of specimens (CNCI), we decided to interpret Acanthopria in a rather broad sense. Once better studied and with its biology known, the genus may be subdivided into several independent genera. Adelioneiva Fischer appears to us as one of those groups and we prefer to treat the genus as a junior synonym. Acan­ thopria belongs to the tribe Diapriini ; it is related both to the large genus Trichopria Ashmead , from which it differs principally by unarmed foretibia, male antennomeres A3 and A4 at least partly fused, and by female antenna nonabrupt and not broadened toward apex; furthermore, most Acanthopria species are distinguished by light color of body compared with generally much darker coloration of Trichopria species. Acanthopria shows also some relationships with myrmecophilic genera of the Diapriini such as Labidopria Wasmann ; Leucopria , new genus; Mimopriella , new genus; etc. Acanthopria differs from them by the absence of specialized spot on S2 or by normal, i.e., noncompressed tarsi. Contrary to frequent coriaceous sculpture in ecitophilus genera, almost all species of Acanthopria known to us have smooth bodies. Acanthopria differs from Eladio , new genus, by the absence of a specialized comb of setae on hind tibia, and by nonsculptured body.

DISTRIBUTION: Acanthopria is largely Neotropical in distribution, with only one undescribed species extending to Florida and two in Texas. The greatest species diversity seems to be in lowland rainforests of Central and South America. We examined specimens from Antilles, Mexico to Brazil, and north of Argentina. The genus is not represented in high elevations of tropical America (above 2500 m) and does not occur in Chile.

BIOLOGY: The hosts are not known for any species. However, several observations ( Ferrière, 1929; Borgmeier, 1939; Mann, 1918) indicate close association of Acanthopria species with ants (army ants, leafcutting ants). A series of females in CNCI was collected in Costa Rica rainforest attempting to enter a nest of leafcutting ants viz. Cyphomyrmex sp. (Attini) . Nevertheless, Acanthopria species studied by us do not exhibit any advanced morphological adaptations as known among true myrmecophiles (e.g., Mimopria Holmgren ; Mimopriella , new genus; Notoxoides Ashmead ; Philolestoides Ferrière ). Numerous light­colored species of Acanthopria are presumed to be nocturnal, as inferred from rich material collected in light traps in lowland Brazil and Panama (CNCI).

TYPE SPECIES: Apopria coveri , new species (described below), by present designation.

RECOGNITION AND RELATIONSHIPS: Apopria is recognized on number of unique, extreme apomorphic states reflecting its close association with the host ants: loss of eyes, ocelli, palpi, wings, and tibial spurs, furthermore by development of special projections on fore and mid basitarsi, presence of large deep depression on upper mesopleuron, as well as unique massive, tonguelike dorsellum. Apopria appears to share some character states with Ecitovagus and Myrmecopria ; structure of propodeum and metasoma past petiole, as well as type of antenna, is shared with Ecitovagus ; shape of head, reduction of palpi and tibial spurs, pustulae on femora and A1, are shared with Myrmecopria . The tendency to reduce palpi and tibial spurs, as a manifestation of a high degree of integration with the host ant, has started in Myrmecopria and culminates in Apopria .

ETYMOLOGY: The prefix apo (Greek for without) refers to loss of organs such as eyes, ocelli, palpi, and tibial spurs, the Latin word pria means ‘‘a little wasp’’. The gender is feminine.

MALE: Unknown.

DISTRIBUTION: Two species are known to us from Florida.

BIOLOGY: Apopria coveri was originally collected from bivouac of ecitonine ant Neivamyrmex opacithorax (Emery) (det. S. Cov­ er) in the very center of the colony, deep underground, in total darkness. Judging from the loss of wings, eyes, and ocelli we assume that the life cycle and dispersal strategies of Apopria are entirely different from all symphilic genera of Diapriinae known to us in which eyes and ocelli are developed and wings primarily present ( Huggert and Masner, 1983). A. coveri probably disperses underground with the newly budding colonies of the host ant. The second species, to be described later, sympatric with A. coveri , was collected in a colony of Neivamyrmex carolinensis (Emery) (det. M. Deyrup).

METASO­ MA. Petiole with same granular rugulosity as in propodeum, petiole slightly wider than posterior constricted part of propodeum (28: 25), petiole ventrally covered with shorter dense whitish semidecumbent hairs, narrow posterior constricted part of petiole (in front of syntergite) smooth and shining; metasoma past petiole rather robust, distinctly wider than mesosoma (62:36), longer than wide (105:62).

TYPE MATERIAL: 24♀. Holotype, ♀ ( CNCI no. 22448), USA, Florida, Citrus Co., Pine­ Oak Estates, 7.9 mi NE Jct. Rt. 98 on Rt. 488, April 1 1993, S.P. Cover 3471; disturbed longleaf Pine­Turkey Oak woodland with grassy understory, bivouac under rotten pine stump; with Neivamyrmex opacithorax (Emery) , det. S.P. Cover 1993. Holotype mounted on point, well preserved except for left mid tibia and tarsus and tarsomeres 3–5 of hind left leg missing. Paratypes, 23♀, USA, Florida, Alachua Co., Gainesville, 29°34̍30̎N, 82°29̍00̎W, February 23 to May 23, 1991 –1994, R. Lundgren, all associated with Neivamyrmex texanus Watkins (det. M. Deyrup) ( CNCI, MIZA, NHM).

ETYMOLOGY: The new species is named in honor of Mr. Stefan Cover (Museum of Comparative Zoology, Cambridge, USA), who collected the first specimen (holotype). Mr. Cover also kindly supplied information on the biology and behavior of the host ant (see above).

DISTRIBUTION: Florida.

BIOLOGY: It is interesting to note that A. coveri is associated with both Neivamyrmex opacithorax and N. nigrescens . Mr. Lundgren (personal commun.) collected numerous individuals in spring under logs and rocks; the wasps moved with ants in a very similar manner, making their recognition rather difficult for the collector.

VARIATION: The only variations in the type series are slight differences in the body length.
