NEW GENERA AND SPECIES OF NEOTROPICAL
AMISEGINAE (HYMENOPTERA, CHRYSIDIDAE)*
BY LYNN SIRI KIMSEY

The Canadian National Collection (OTTAWA) has one of the largest, if not the largest collection of neotropical Amiseginae in the world. In a sample of about 700 unidentified specimens sent to me by Lubomir Masner from this collection there were many new taxa, including representatives of a new genus, In addition, material was borrowed from the Museum of Comparative Zoology, Harvard University (J. M. Carpenter), Cambridge, Massachusetts, the Amer- ican Entomological Institute, Gainesville, Florida (H. Townes, GAINESVILLE), and the U.S. National Museum, Washington, D.C. (K. V. Krombein, WASHINGTON). The new species of AdeZphe are described separately (Kimsey 1986). The remaining new taxa are included below.
The following abbreviations are used: F = flagellomere, MOD = midocellus diameter, PD = puncture diameter and T = gastral tergum.

Species distinctions in this group are difficult, and color patterns tend to be more useful than structural measurements. Unfortu- nately, unlike most chrysidids, male Amisega tend to be structurally

conservative and have few color differences between species. Because of this difficulty with males, holotypes of most of the fol- lowing new species are females.
Amisega belizensis Kimsey, new species
Holotype female. Body length 3.5 mm. Face with fine striatiform punctures, scapal basin densely cross-ridged; malar space 1.3 MOD; eye in lateral view widest at midline; postocellar area covered with fine transverse striae and punctures; F-I 4X as long as broad; F-11 length 2.5X breadth; pronotum and scutum covered with striatiform punctures, with transverse striae on pronotum; scutum without notauli; scutellar punctures irregularly spaced 0.2-2.0 PD apart, faintly striatiform anteriorly; mesopleuron with punctures densely clumped on anterior half, posterior area smooth and impunctate; propodeal enclosures smooth and impunctate; T-I and 111-IV nearly impunctate, except for a few widely scattered tiny punctures; T-I1 with small anteromedial patch of tiny punctures, otherwise im- punctate.
Head, pronotum, scutum, scutellum and metanotum coppery; rest of thorax and propodeum with faint blue-green tint; terga black, except T-1-11 with a lateral bluish spot; antenna dark brown; legs, including coxae, red, except posterior half of hind- femur dark brown; wings brown-stained with unstained medial stripe across wing at stigma.
Male. Same as female, except wing color fainter, body with green tints, coxae and femora dark brown, and tibiae and tarsomeres red. Holotype female-BELIZE: Middlesex, 125m, 15 April 165, E. C. Welling (OTTAWA). Paratypes: 1 female and 2 males, same data as type except 27 April 1965, 3 April 1965 and 15 March 1965. Discussion. The female of belizensis can be readily distinguished by the pale legs, coppery head and thorax and banded wings. Males are more difficult to distinguish but their legs tend to be pale api- cally, the notauli are essentially absent and the mesopleural puncta- tion is distinctive.
Amisega bennetti Kimsey, new species
Holotype female. Body length 3 mm. Face with fine contiguous punctures; scapal basin cross-ridged with scattered punctures; malar space 1.2 MOD; eye in lateral view widest at midline; F-I length 4X

breadth; F-I1 length 2X breadth; postocellar area finely transversely striate, with scattered punctures 1-3 PD apart; pronotum, scutum and scutellum covered with fine transverse striae and small shallow punctures 1-3 PD apart; scutum with notauli present posteriorly and absent anteriorly; mesopleuron smooth with moderate punc- tures along anterior half, 0.2-1.0 PD apart; propodeal enclosures smooth and impunctate; T-I with transverse band of small punc- tures along posterior margin; T-I1 with small punctures clumped anteromedially; T-111-IV with tiny punctures along posterior mar- gin. Face with green highlights; vertex coppery; thorax with bluish green highlights; abdomen dark brown without metallic highlights; antenna dark brown, except F-I yellow; legs including coxae yellow. Male. Same as female, except body color greener; antenna entirely dark brown; coxae, femora and most of tibiae dark brown; tarsomeres paler and reddish, and scapal basin often smooth with- out transverse striae.
Holotype female-TRINIDAD, W. I., Curepe, Santa Margarita, 1-14 January 1974, E. D. Bennett (OTTAWA). Paratypes: 59 females and 302 males, same data as type except dates between January and December 1974 and 3 March 1961 (2 males), and 1 male: Piarco, 27 February 196 1.
Discussion. A. bennetti andflavicrus are very similar and can be most readily separated by the color of the female antenna and legs. Otherwise bennetti can be distinguished by the evenly rounded pronotum, notauli indicated by a fine line; and the mesopleural punctation.
Amisega bicolor Kimsey, new species
Holotype female. Body length 3.5 mm. Scapal basin with smooth impunctate areas, without cross-ridging; frons to postocellar area appearing granular with contiguous small punctures and without striae; pronotum, scutum and scutellum same as vertex, without striae; malar space 1.5 MOD; eye in lateral view widest medially; F-I 4X as long as broad; F-I1 length twice breadth; mesopleuron with dense nearly contiguous punctures on anterior two-thirds, posterior part smooth and largely impunctate; dorsal propodeal enclosures finely rugose; T-I with few very scattered punctures; T-I1 with small anteromedial clump of punctures. Head, scape and thoracic dorsum

Male. Same as female, except somewhat darker on T-I and I1 with more punctures.
Holotype female-MEXICO: Sinaloa, 20 mi. e. Concordia, 3000 ft., 12 August 1964, W. R. M. Mason (OTTAWA). Paratypes: 3 males and 3 females; Sinaloa: 5 mi w. El Palmito, 5000 ft., July 1964, W. R. M. Mason and L. Kelton (2 males, 3 females); Vera- cruz: Catemaco, 1 100 ft., 16- 18 June 1969 (1 male). Discussion. Of the species with pale legs bicolor most closely resembles striata, based on the sculpture of the mesopleuron and propodeal enclosures. A. bicolor can be distinguished by the bicol- ored hindfemur, the entirely dark scape and bluer thoracic color. Amisega chiapana Kimsey, new species
Holotype female. Body length 3 mm. Face finely cross-ridged in scapal basin, with transversely striatiform punctures on from and vertex; malar space 2 MOD; eye in lateral view widest at midline; postocellar area with fine transverse striae and punctures; F-I length 3.5X breadth; F-I1 length twice breadth; pronotum, scutum and scutellum with punctures striatiform; scutum with notauli only indi- cated faintly anteriorly; mesopleuron with dense punctures on ante- rior two-thirds, posterior third polished and impunctate above scrobe, rugose below; propodeal enclosures finely striate; T-1-11 with very scattered punctures. Head and thorax with light green tints laterally; antenna dark brown, except scape yellow; coxae, trochanters and base of femora yellow, rest of foreleg yellowish brown, rest of mid and hindleg brown; wings brown stained. Male. Same as female, except head and thorax blue-green, legs and antenna entirely dark brown, and T-11 usually with small ante- remedial patch of punctures.
Holotype female: MEXICO: Chiapas, 20 mi. n. Bochil, 5700 ft., Yerba Buena, 24 June 1969 (OTTAWA). Paratypes: 2 males and 7 females; same data as type (2 males, 5 females); Yerba Buena, 5800 ft., 18 June 1969, Mason (2 females); Chiapas: se. side of Cerro Tres Picos, 28 May 1972, D. E. Breedlove (1 female). Discussion. This species belongs to the group that has dark legs even in the females. A. chiapana most closely resembles evansi based on the finely sculptured propodeal enclosures, densely punc- tate mesopleuron and obsolescent notauli. It can be distinguished

Face long and narrow (fig. 5), appearing granular, with fine contiguous punctures; scapal basin finely cross-ridged; malar space 1.3 MOD; eye in lateral view widest slightly above midline (fig. 7); F-I 4X as long as broad; F-I1 length 2X breadth; postocellar region transversely striate with small punc- tures 2-4 PD apart; pronotum more coarsely transversely striate, becoming smooth along posterior margin, punctures small and scattered 1-4 PD apart; scutum with some cross-striate between notauli and parapsides, notauli strong posteriorly and faint ante- riorly, punctures 1-2 PD apart; scutellum smooth, punctures 2-5 PD apart; propodeal enclosures smooth and impunctate; mesopleu- ron smooth with punctures clumped along anterior half, nearly con- tiguous; T-I with transverse band of small punctures before posterior margin; T-I1 with large anteromedial zone of small punc- tures; T-111-IV with transverse band of small punctures before pos- terior margin; T-I1 with large anteromedial zone of small punctures; T-111-IV with transverse band of dense small punctures along poste- rior margin. Face green with brassy tints medially, thorax with greenish tints; terga blackish, except lateral triangular spot on T-I bluish; scape dorsobasally dark brown; remainder of scape, pedicel and F-1-111 yellow, apical flagellomeres dark brown; legs, including coxae yellow; wings brown-tinted.
Male. Same as female except body color darker, and antenna and legs dark brown.
Holotype female-TRINIDAD: W. I. Curepe, CIBC lab. grounds, 14-28 May 1974, E. D. Bennett (OTTAWA). Paratypes: 75 males, 46 females; same data as type, except dates between Janu- ary 1974 and January 1977 (57 males, 42 females); St. Augustine (2 males); Simla, 5 mi. n. Arima (3 males, 3 females); Morne Bleu (3 males); Curepe (2 males); Piarco (2 males), Arima Ward, Aripo Valley (1 male), Trinidad (6 males, 2 females). Discussion. A. flavicrus females are distinctly colored and can be immediately recognized by the brassy green head and thoracic color, and yellow legs and scape to F-111. Both sexes have a long narrow

Amisega flavipes Kimsey, new species
Holotype female. Body length 3 mm. Scapal basin with dense transverse striae; vertex punctures touching to 2 PD apart; postocel- lar area without transverse striae except at posterior margin; malar space 1.5 MOD; F-I length 4X breadth; F-I1 length 2.3X breadth; pronotum coarsely transversely striate; scutum without notauli or transverse striae, scutellum without transverse striae; mesopleuron less than half punctate, posterior part smooth and impunctate; propodeal enclosures smooth; T-I with narrow transverse band of small punctures; T-I1 with anteromedial punctate area; T-111-IV with few minute punctures. Head and thorax, including propodeurn blue; antenna dark brown, except scape paler beneath; legs includ- ing coxae yellow; terga blackish; wing membrane faintly brown- stained.
Male. Same as female except darker; scape entirely dark; legs dark brown, except fore and midtibiae and basal tarsomeres yellow- ish; T-I1 with purple tints.
Holotype female-BRAZIL: Bahia, Encruzilhada, November 1975, M. Alvarenga (GAINESVILLE). Paratypes-4 males and 8 females, same data as type, except some also collected by Seabra and Oliveira.
Discussion. A. flavipes is one of the 3 South American species with yellow legs and dark antenna in the female. It can be distin- guished from perviridis and semiflava by the entirely yellow legs, black T-11, and the dorsum of the head without striation. Males can be recognized by the long malar space, purple T-11, dark legs and striate scapal basin.
