Abstract Four new trogiomorphan Psocoptera are described from the Lower Cretaceous Lebanese amber, viz. Bcharreglaris amunobi n. gen., n. sp., Setoglaris reemae n.gen., n. sp., Libanoglaris chehabi n.sp., and Libanoglaris randatae n. sp. These discoveries show that the Lower Cretaceous biodiversity of the Trogiomorpha was very high. Résumé Quatre nouveaux Psocoptera de l ambre du Liban (Insecta: Psocomorpha:Trogiomorpha). Quatre Trogiomorpha sont décrits des ambres du Crétacé inférieur du Liban: Bcharreglaris amunobi n. gen., n. sp., Setoglaris reemae n. gen., n. sp., Libanoglaris chehabi n. sp. et Libanoglaris randatae n. sp. Ces découvertes montrent que la diversité de ce groupe était très importante au Crétacé inférieur. Recent works have greatly increased our knowledge on the palaeodiversity of the psocopteran group Trogiomorpha during the Cretaceous, through studies of the faunas in ambers from France and Spain (Baz and Ortuño 2000, 2001; Perrichot et al. 2003). Azar et al. (in Perrichot et al. 2003) described the new genus and species Libanoglaris mouawadi from the Lebanese amber (Hammana/Mdeyrij outcrop, Central Lebanon). But the diversity of this group in Lebanese amber was even greater than supposed as we now describe four different new taxa from three Lebanese amber outcrops. We follow the wing venation nomenclature and body structures of Badonnel (1943), Smithers (1972), Mockford (1993) and Lienhard (1998).

Abdomen 0.7 mm long and 0.34 mm wide, poorly preserved, covered by a white matter, genitalia not visible and covered by gas bubbles. Discussion After Smithers (1972, 1990) and Leinhard (1998), Bcharreglaris amunobi n. gen and sp. falls into the Prionoglarididae because of several diagnostic characters of this family: (1) antenna long; (2) forewing without sclerotized pterostigma; (3) nodulus present; (4) tarsi three-segmented; (5) presence of a preapical tooth on tarsi; (6) forewing with Sc strongly curved and meeting R1. Bcharreglaris amunobi n. gen and sp. differs from the extant prionoglarid genera Prionoglaris, Speleketor, and Sensitibilla in its forewing cell between R, Rs and first cross-vein between them narrow elongate, instead of 186

3 Amber Psocoptera being short and nearly as broad as long, and wing ciliation well distinct (Smithers 1972; Lienhard 2000). The fossil family Archaeatropidae Baz and Ortuño, 2000 (unique genus Archaeatropos Baz and Ortuño, 2000) have a wing venation very similar to those of the extant Prionoglarididae. After Perrichot et al. (2003), the separation between the two families is poorly supported and would need confirmation. Because of this confuse state of the art, it is not possible to accurately attribute a fossil taxon to the Archaeatropidae rather than to the Prionoglarididae. Nevertheless, Bcharreglaris amunobi gen. and n. sp. is strongly similar to the Lower Cretaceous genera Proprionoglaris Perrichot et al., 2003, Prospeleketor Perrichot et al., 2003, and Archaeatropos. It differs from Archaeatropos in the following points: pterostigma short and triangular, instead of elongate and quadrangular; absence of setae in pterostigma; presence of numerous long setae in anal and axillar areas. Bcharreglaris amunobi n. gen. and sp. shares with Libanoglaris mouawadi Azar et al. (in Perrichot et al. 2003), the presence of a short forewing Sc, perpendicular to R and anterior wing margin. They differ in the following characters: (1) Bcharreglaris amunobi n. gen. and sp. has 25 antennal flagellomeres instead of 22; (2) some of its flagellomeres are secondarily annulated; (3) its pterostigma is triangular-shaped, instead of being trapezoid-shaped in L. mouawadi.

5 Amber Psocoptera tooth on tarsal claw (absent or very small in Archaeatropos); and absence of secondary annulations on antennomeres. Both these characters of L. randatae are also present in Libanoglaris mouawadi. Nevertheless, L. randatae shares with Archaeatropos the fore wing vein Sc directed towards wing base; and fore wing Rs perpendicular to R1 (but some specimens of Archaeatropos have a Rs oblique). These venational characters are not present in L. mouawadi, but they are of specific rather than of generic importance, unlike the antennal annulations. L. randatae differs from L. mouawadi in the characters listed above in its diagnosis (Perrichot et al., 2003).

Abdomen 0.84 mm long and 0.42 mm wide; male genitalia: not visible and covered by gas bubbles; female genitalia with rather long valvulae (probably V3?). Discussion After Smithers (1972, 1990) and Leinhard (1998), Libanoglaris randatae n. sp. would fall into the Prionoglarididae because of several diagnostic characters shared with this family: (1) forewing without sclerotized pterostigma; (2) nodulus present; (3) tarsi threesegmented; (4) presence of a preapical tooth on tarsi; (5) forewing with Sc strongly curved and meeting R1.

Hind wing hyaline, smaller than fore wing, 1.0 mm long and mm wide; Sc not visible because of bad preservation state of basal part of hind wing; Rs fused with M for a short distance; distance between distal separation of Rs from M and fork of Rs into R2 + 3 and R mm; basi-radial cell fourangled but very difficult to see; R mm long; R mm long; M basally fused with Cu1 for a short distance; distal free part of M 0.21 mm long, basal of its fork into M1 and M2; M mm long; M2 shorter than M1, 0.18 mm long; Cu1 reaching wing margin, 0.54 mm of wing base; anal area hidden by fore wing. Abdomen 0.60 mm long and 0.30 wide, poorly preserved, covered by a white matter, female genitalia with rather long valvulae (probably V3?). Discussion After Smithers (1972, 1990) and Leinhard (1998), Setoglaris reemae n. gen. and sp. falls into the Prionoglarididae because of several diagnostic characters of this family: (1) antenna long; (2) forewing without sclerotized pterostigma; (3) nodulus present; (4) tarsi three-segmented; (5) presence of a preapical tooth on tarsi; (6) forewing with Sc strongly curved and meeting R1. After the keys proposed by Baz and Ortuño (2000, 2001), Setoglaris reemae n. gen. and sp. falls into the fossil family Archaeatropidae because of several diagnostic characters: (1) presence of spur sensilium on mx2; (2) ovipositor valvulae (V3) elongated; (3) nodulus present. In addition Setoglaris reemae shares with Archaeotropos alavensis Baz and Ortuño, 2000 similar wing venations; presence of secondarily annulations on flagellomeres, and pterostigma area with setae. Setoglaris reemae differs form Archaeotropos alavensis Baz and Ortuño, 2000 in the shape of its pterostigma and the presence of tarsal claws with one preapical tooth. Setoglaris reemae has a wing venation very similar to that of Libanoglaris chehabi, but it differs form the Libanoglaris spp. in its elongate and secondarily annulated flagellomeres. Setoglaris reemae shares with Bcharreglaris amunobi the secondarily annulations on flagellomeres, and differs from it in the absence of setae in its pterostigmal area and in the presence of setae in the anal and axillar areas of the latter.
