962C87CAAB44FFCDFCFB61E29A5F5D57.taxon	diagnosis	DIAGNOSIS: Augochlorines are most readily recognized from other Halictinae by their brilliant metallic coloration; however, this is not a universal character, being neither unique to nor fixed across Augochlorini. The medio-apical cleft of the female fifth metasomal tergum and the absence of a pygidial plate on the apical margin of the male seventh metasomal tergum separates Augochlorini from other Halictinae. Among New World halictines, the augochlorines are most similar to (and likely most closely related to) genera of the Caenohalictus and Agapostemon generic complexes; these groups also frequently exhibit metallic-green body coloration.	en	ENGEL, MICHAEL S.

962C87CAAB44FFCDFCFB61E29A5F5D57.taxon	discussion	COMMENTS: A potential larval character for the Augochlorini is the development of the mandibular cusp into an acute, elongate projection (McGinley, 1981). Larvae, however, are known for only a few, scattered genera (table 2) and until further work on augochlorine immatures is undertaken, the validity of this character in supporting the monophyly of the tribe remains uncertain. Authorship of the tribe has universally been given to Moure (1943 a). In actuality Beebe (1925), in a semipopular treatment of the fauna of Guyana, mentions the name ‘‘ Augochloridae ’’ to include tropical species of the genera Augochlora and Halictus. Although Beebe (op. cit.) proposed the group cavalierly, he is to be considered as the correct author of the family-group name based on Augochlora (Engel, 1999 b).	en	ENGEL, MICHAEL S.

From the former group, Andinaugochlora can be separated by the broadly rounded mesoscutal anterior border and the obsolescent anterior border to the metabasitibial plate, while from the latter genus it differs in these same characters and also by the nearly orthogonal epistomal sulcus and carinate preoccipital ridge.	en	ENGEL, MICHAEL S.

REVISIONS: Refer to subgeneric treatments. Michener (1954 b) gave a key to the Panamanian species and Cockerell (1897 b) provided a key to the Mexican species; however this latter key is somewhat out of date and should be used with caution. Neither of these keys utilize the currently recognized subgeneric groupings and species identities should therefore, be cross-referenced with Moure and Hurd (1987) for subgeneric associations and appropriate synonymies.

962C87CAAB43FFCEFD3B657499AF5BE9.taxon	diagnosis	DIAGNOSIS: This monotypic subgenus is unique among Augochlora species in the absence of a preoccipital carina, instead having an entirely rounded preocciptal area (a derived feature among the enitre Augochlora - group of genera). The acute epistomal sulcus places it among Augochlora, but the lobe is very small, in this way differing from living species of the genus. The orbicular basal elevation on the labrum is similar to Oxystoglossella, but in this subgenus the elevation is strongly protuberant.

962C87CAAB7FFFF3FCE066CE9B975FBC.taxon	diagnosis	DIAGNOSIS: The species of Glyptochlora are the most distinctive among all Augochloropsis species. The coarse punctation of the body resembles to some degree that of the cleptoparasitic genus Temnosoma. The extremely short vertex, sharply carinate preoccipital ridge, and the strongly narrowed and lamellate anterior border of the mesoscutum separate Glyptochlora from all other Augochloropsis.	en	ENGEL, MICHAEL S.

962C87CAAB7AFFF9FD3B613199A058C7.taxon	diagnosis	DIAGNOSIS: This is a large genus of nocturnal bees exhibiting the typical characters of large ocelli and pale integumental pigmentation. Megalopta is related to the genus Xenochlora, but this group has normal-sized ocelli, lacks the densely packed, single series of distal hamuli, and has stiff, black setae on the hindlegs. Among the other nocturnal genera, Megaloptidia and Megommation, Megalopta lacks the strongly narrowed and elongate prementum and the pointed galeal apex. The pectinate inner metatibial spur and densely packed hamuli can also separate Megalopta from other nocturnal augochlorines.	en	ENGEL, MICHAEL S.

962C87CAAB75FFF8FF1A678C99935BDC.taxon	diagnosis	DIAGNOSIS: This is a genus of moderately large, robust, nocturnal bees generally resembling the larger nocturnal genus Megalopta they were at one time included as a subgenus. The genus can be readily separated from Megalopta by the narrowed, elongate prementum, the serrate inner metatibial spur, the enlarged compound eyes, and the irregularly spaced distal hamuli. Like most nocturnal bees, species are generally pale in coloration and have greatly enlarged ocelli.	en	ENGEL, MICHAEL S.

Type species: Megalopta minuta Friese, 1926, monobasic and original designation. DIAGNOSIS: This cleptoparasitic subgenus can be quickly identified by the simple, bladelike mandibles (fig. 15), the absence of a basitibial plate, and the absence of a scopa. It is most similar to Megaloptina, both sharing the dense, plumose setae surrounding the propodeal spiracle in males. Megaloptina, however, is not parasitic and has a well-developed scopa, a basitibial plate, and normal mandibles. The serrate inner metatibial spur also distinguishes Cleptommation from Megaloptina. DESCRIPTION: As for the genus with the following additions: Female. Mandible simple, bladelike (fig. 15). Labral basal elevation absent; teeth absent. Clypeal apex relatively straight. Hypostomal ridge carinate. Ocelli not greatly enlarged. Pronotal dorsal ridge rounded. Mesoscutal anterior border round- ed; mesoscutal lip rounded. Scopa absent Basitibial plate absent. Inner hind tibial spur serrate. Male. Labrum without distal process basal area not notched. Antenna extending back to scutellum or metanotum; F 1 longer than F 2.

The only other augochlorine with an acarinarium is the South American genus Thectochlora. Oligochlora is distinguished from Thectochlora by an unproduced pronotal lateral angle, absence of a lamella on the pronotal dorsal ridge, a broadly rounded mesoscutum, absence of a dorsal hook on the mesotrochanter, and abence of dense tomentum on the basal area of the propodeum.	en	ENGEL, MICHAEL S.

Anterior surface T 1 weakly modified into an acarinarium. Male. Unknown. REVISIONS: At present this group contains three species. The subgenus was newly diagnosed by Engel (1997 a) based on the discovery of a third species. PALEOBIOLOGY: Two of the three species of Oligochlora are associated with astigmatid mites (Engel, 1996 b; Fain et al., 1999). Mitebee associations are common, although poorly understood (Eickwort, 1979 b, 1994; Fain et al., 1999). Oligochlora, like the genus Thectochlora (see below), possesses an acarinarium on the first metasomal tergum suggesting a mutualistic association between these ancient bees and mites.

962C87CAAB73FFE3FCCF601299C05B99.taxon	diagnosis	DIAGNOSIS: Pereirapis generally resembles species of the more common genera Augochlorella and Augochlora. It can be separated from the latter genus by the absence of a deeply acute epistomal sulcus that projects into the base of the clypeus and by the acute marginal cell apex. Pereirapis differs from Augochlorella in the presence of a large basal lobe on the inner metatibial spur. Pereirapis are small, brilliant metallic bees that are frequently green, with some populations slightly bluish and others more cupreous.	en	ENGEL, MICHAEL S.

962C87CAAB73FFE3FCCF601299C05B99.taxon	discussion	COMMENTS: This group has generally been known under the name Pseudaugochloropsis by recent authors (e. g., Eickwort, 1967 Michener, 1974; Eickwort and Sakagami 1979; Moure and Hurd, 1987; Roubik, 1989 Michener et al., 1994; Radchenko and Pesenko, 1994 b; Griswold et al., 1995; Danforth and Eickwort, 1997). However, the type species of Pseudaugochloropsis is a species of Augochloropsis (Paraugochloropsis), and thus the valid name for the genus is Pseudaugochlora (see also discussions in Michener, 1954 b, 1994). As if this confusion were not enough, the type species of this genus has been consistently cited as Halictus nigromarginatus Spinola, 1851 (Eickwort, 1969 a Michener, 1994, 1997), which is obviously a homonym of the actual type species of Pseudaugochlora (namely, H. nigromarginatus Spinola, 1841). Spinola’s 1851 nigromarginatus is in actuality a species of Caenohalictus (= Caenohalictus oblitus Moure and Hurd 1987).

962C87CAAB73FFE3FCCF601299C05B99.taxon	diagnosis	DIAGNOSIS: This is one of the most distinctive genera of Augochlorini. The coarse sculpturing of the body gives these cleptoparasitic bees the general appearance of chrysidid wasps. Among augochlorine genera, Temnosoma ’ s appearance comes closest to species of Glyptochlora. Temnosoma can be separated from Glyptochlora by an oval tegula, absence of a scopa, the depressed apical margins of the first two metasomal terga, absence of a medio-apical cleft in the fifth metasomal tergum of females, and the presence of a broad division in the seventh metasomal tergum of males, among other characters.	en	ENGEL, MICHAEL S.

962C87CAAB6FFFE2FF3661AA9A205CD9.taxon	diagnosis	DIAGNOSIS: This is the most primitive group of Augochlorini and is restricted to southern South America. The species are generally small, although females of at least one species, R. inflaticeps, can be moderately large. Most species are dull metallic (except Callistochlora) or nonmetallic in coloration. The presence of a strong galeal comb, the short galea that extends posteriorly only halfway to the stipital base, and the short median process on the premental apex all serve to separate this group from the larger and more diverse Augochlorina.	en	ENGEL, MICHAEL S.

962C87CAAB0EFF82FCDD64DA9B795C25.taxon	discussion	COMMENTS: Two synonymies are proposed above even though I have not had the opportunity to examine the type material firsthand. The first is H. caucasicus the holotype for which is located in the Institute of Systematic Zoology, Polish Academy of Sciences, Krákow. According to the curator the holotype is in poor condition and not suitable for shipment (W. Celary, personal com- mun., 1996). Father Ebmer (1977), however, had examined the type and considered it identical to A. seminigra and A. bidentata. I have seen the types of both A. seminigra and A. bidentata and am confident of Ebmer’s comparisons. I therefore have considered H. caucasicus as identical to these latter two taxa and thereby as a synonym of H. semiauratus. I have also not had the opportunity to see Padre Moure’s types of P. rhizophila (located in DZUP), although I have seen specimens of this species identified by Moure. In 1944 and 1950 Moure considered his species as a synonym of A. seminigra. I am similarly confident with Moure’s determination which accords with the specimens identified by him that I have examined. I therefore consider P. rhizophila as a synonym of H. semiauratus.	en	ENGEL, MICHAEL S. (2000): Classification Of The Bee Tribe Augochlorini (Hymenoptera: Halictidae).
