Cretaceomma RASNITSYN & MAALOUF & MAALOUF & AZAR 2022, gen. nov.
No full textGenus Cretaceomma Rasnitsyn & Azar gen. nov. Type species. Cretaceomma libanensis sp. nov.; by present designation. Other species. Galloromma turolensis Ortega et al., 2011a, transferred herein to Cretaceomma gen. nov. Etymology. The genus name combines parts of Cretaceous and Galloromma. Diagnosis. Female antenna 14-segmented with 7- segmented funicle and 5-segmented loose (movably interconnected) clava. Pronotum reaching wing base or nearly so. Remarks. New genus differs from the type genus of the family Galloromma Schlüter, 1978 in more polymerous antenna (13-segmented with 4-segmented club in Galloromma) and pronotum apparently reaching wing bases (shortened posterolateral and far not reaching wing bases in Galloromma). Galloromma turolensis Ortega et al., 2011 from the Albian San Just amber in Spain is similar to the type species in above characters and that is why it is transferred to the new genus.Published as part of RASNITSYN, ALEXANDR P., MAALOUF, MOUNIR, MAALOUF, RAMY & AZAR, DANY, 2022, New Serphitidae and Gallorommatidae (Insecta: Hymenoptera: Microprocta) in the Early Cretaceous Lebanese amber, pp. 120-136 in Palaeoentomology 5 (2) on pages 128-129, DOI: 10.11646/palaeoentomology.5.2.4, http://zenodo.org/record/653041

No full textLeptoserphites iriae Rasnitsyn & Azar, sp. nov. (Figs 6–8) Type material. Holotype, female, specimen no QBC- 16A (Fig. 6A–C), Maalouf collection, complete insect partially distorted postmortem (possibly diagenetically due to plastical deformation of enclosing amber under uneven pressure of deposits); paratypes, QBC-16B (Fig. 6D) and QBC-16C (Fig. 6E, F), Maalouf collection, synincluded with holotype in the same piece of amber and still more suffered from deformation (QBC-16B is particularly poor and included mainly being synincluded and having similar wing venation). All type material is from Qanat Bakish (Baskinta) amber outcrop, Mouhafazet Jabal Loubnan (Governorate Mount Lebanon), Caza (= District) El-Maten, Central Lebanon; lower Barremian. Type material is deposited in the Natural History Museum of the Lebanese University, Faculty of Sciences II, Fanar, Lebanon. Etymology. Specific name is after Iria Maalouf Alonso, daughter of one of us (RM). Diagnosis. Differs from the type species (L. pabloi sp. nov.) in having antenna 11-segmented with no clear traces of fusion of two basal flagellomeres into one, flagellomeres longer, propodeum transridged, pterostigma wider, 2r-rs shorter, no tubular structures present but R and pterostigma, hind wing with no r-m, petiolar segments longer. Locality and horizon. Baskinta, in the locality of Qanat Bakish (33°57′3″N, 35°47′24″E, elev. 1,488 m), Caza (= District) El-Maten, Mouhafazet (= Governorate) Mount Lebanon, in Central Lebanon; lower Barremian. Description. (Based on holotype otherwise stated) Female. Color dark fuscous, legs paler. Body with no surface sculpture and prominent vestiture discernible. Head elongate as preserved (Figs 7A, 8A, both on paratype QBC-16C) (possibly due to deformation), with eyes small, not much convex, placed before middle of head sides (more rostrally). Antenna 11-segmented [Figs 8A (paratype QBC-16C), 8D (holotype)], with scape long and wide, about as long as next three or four antennomeres combined, pedicel shorter than some apical segments, flagellum wide, somewhat flattened, slightly narrowing toward base, most segments longer than wide, basal flagellomere slightly longer than next one. Distinct subequal mandibles, right with three teeth and left with two ones. Of maxillary (Fig. 8B) and labial palps (Fig. 8C), only their elongate apical segments visible. Mesosoma with dorsal pronotal part apparently short, mesoscutellum in side view with hind part somewhat elevated,metascutum forming high step above wide trough of metapostnotum, propodeum short, gently arching toward metasomal base in side view, transridged. Forewing (Fig. 8E) with C, R behind pterostigma, RS before and behind 2r-rs (except for short section forming “ T ” pattern together with 2r-rs), M+Cu and M lost as pigmented veins or nearly so; R and pterostigma tubular; RS &M, 2r-rs and 1-Cu nebulous; pterostigma high (distinctly less than twice as long as wide), together with 2r-rs enclosed in lightly pigmented area; 2r-rs half as long as pterostigma wide; all membrane covered with short setae (margin included). Hind wing (Fig. 8F) with only R pigmented (tubular), R apex with three hamuli, hind margin with fringe of long setae. Legs ordinary except that fore tibial spur (calcar) straight except bent subapical with bifid apex (Fig. 8G), and fore basitarsus excised almost for all its length and with single row of setae along excision; tibial spurs 1: 1: 2; tibiae and tarsomeres 1–4 with stiff apical setae, mid and hind tibiae also with thick setae ventrally in distal half or so, basitarsi shorter than or (fore basitarsus) subequal to tarsomeres 2–4 combined, tarsomeres 3–4 almost equal in length, elongate, claw simple, arolium about as long as claw. Metasoma with petiolar segments very long, with no rough sculpture apparent, first segment slightly longer (in holotype) or shorter (in QBC-16C) than second [Figs 7B, 8I (in QBC-16C), 8H (holotype)], petiolar attachment to gaster frontal. Ovipositor straight, partially external (longest visible in QBC-16C, Fig. 8I). Measurements. Holotype: body length, 1.4 mm, head length, 0.30 mm, antenna length, 0.51 mm, mesosoma length, 0.45 mm, forewing length, 0.80 mm, width, 0.36 mm, first petiolar segment length 0.12 mm, second petiolar segment length 0.14 mm, gaster length (ovipositor excluded) 0.37 mm; paratype QBC-16C: body length, 1.4 mm, head length 0.30 mm, antenna length, 0.60 mm, mesosoma length, 0.45 mm, forewing length, 0.65 mm, width, 0.30 mm, first petiolar segment length 0.15 mm, second petiolar segment length 0.10 mm, gaster length (ovipositor excluded) 0.37 mm; paratype QBC- 1B: body length, 1.4 mm, antenna (deformed) length 0.49 mm, forewing length 0.80 mm, width 0.33mm. Remarks. Holotype and two paratypes are incompletely preserved and so with many features obscure. Yet they are considered as conspecific based on their burial in one and the same piece of amber, their similarity in features less affected with postmortem deformation (wing venation, to an extent also antenna and legs, and, to our wonder, most measurements) and apparent absence of counter-evidence of their conspecifity.Published as part of RASNITSYN, ALEXANDR P., MAALOUF, MOUNIR, MAALOUF, RAMY & AZAR, DANY, 2022, New Serphitidae and Gallorommatidae (Insecta: Hymenoptera: Microprocta) in the Early Cretaceous Lebanese amber, pp. 120-136 in Palaeoentomology 5 (2) on pages 126-128, DOI: 10.11646/palaeoentomology.5.2.4, http://zenodo.org/record/653041

Microserphites libanensis RASNITSYN & MAALOUF & MAALOUF & AZAR 2022, sp. nov.
No full textMicroserphites libanensis Rasnitsyn & Azar, sp. nov. (Figs 1, 2) Type material. Holotype, specimen no 1819V, Azar collection; from Mdeirij-Hammana amber outcrop; Mouhafazet Jabal Loubnan (Governorate Mount Lebanon), Caza (= District) Baabda, Central Lebanon; lower Barremian. Type material is deposited in the Natural History Museum of the Lebanese University, Faculty of Sciences II, Fanar, Lebanon. Etymology. The specific name is derived from Lebanon in Greek, Λίβανος = Libanos. Diagnosis. New species differs from both its congeners in further reduced venation (all veins other than R nebulous or lost, pterostigma reduced up to a colored strip, hind wing with only R preserved and with membrane almost lost basally, and with R not reaching wing midlength) as well as in long, helmet-like head with flat eyes, in smaller size (forewing length under 0.5 mm), and from M. soplaensis also in flagellum much less widened apically. Locality and horizon. Mdeirij-Hammana outcrop (33°48′13″N, 35°43′45″E, elev. 1,340 m), Caza (= District) Baabda, Central Lebanon, lower Barremian. Description. Head, meso- and metasoma brownish, antennae and legs pale, petiole pale brown. Integuments mainly smooth, mesonotum between notauli rugose, propodeum carinate. Vestiture not apparent except wings with abundant longer marginal and shorter surface setae. Head dorsally long trapezoid with straight sides and deeply concave hind margin (Fig. 2A), eyes almost perfectly flat, taking most part of head sides, ocelli large, in almost equilateral triangle, with lateral ocelli close to but not touching eyes, occipital carina not apparent. Antenna 9-segmented (Fig. 2A, B), scape hardly visible, pedicel longer than wide, wider that flagellomeres except apical ones, flagellum gradually widening apicad, with flagellomeres changing from distinctly transverse basal ones to distinctly elongate apical one. Mesosoma with mesonotum strongly convex, pronotum forming wide belt on its fore declivity, posterolaterally not reaching wing base (tegula not identifiable), mesonotum with notauli very wide, not reaching rather long and transcarinate prescutellar fossa, mesoscutellum long with distinct posterior declivity, mesopleuron with complete oblique suture, metanotum following mesoscutellar declivity, with short medial upward tooth, propodeum short, similarly declivitous, with several short medial upward teeth (three, one apicad and two in distal third) and with oblique lateral carina. Legs weak, with coxae small, trochantelli developed, femora and tibiae narrow, femora not much longer than tibiae, tarsi not much longer than tibiae, tarsal segments all elongate, basitarsi much shorter than respective 3 middle tarsal segments but clearly longer than each of them, segment 4 scarcely shorter than segment 3, tibial spurs 1: 1: 2; claw simple, arolium present. Fore wing short, wide, with narrow base embracing all venation (nebulous M+Cu, basal vein [= RS&M] and Cu) except the only tubular vein R and weakly colored strip-like rudiment of pterostigma not reaching basal 0.4 of wing length; pre-radial (costal) membrane not visible. Hind wing with the only vein R present (Figs 1C, 2C), bearing 2 hamuli apical and hardly reaching wing midlength, with wing membrane very narrow before 0.4 wing length and parallel-sided with rounded apex further apical. Metasoma with petiolar segments tubular, of subequal height, first one some twice as long as high, second subquadrate; gaster with petiolar attachment ventral (not frontal), gastral terga 2–3 subequal in length and distinctly shorter than tergum 1; form of metasomal apex and sex unknown. Measurements. Body length 0.65 mm, fore wing 0.47 mm, hind wing 0.33 mm. Remarks. The new species is ascribed to Microserphites based on pronotum not reaching wing base and much reduced wing venation (pterostigma disintegrated, no tubular veins but R, etc.). It is described as new because of deep differences in wing venation and head form (cf. Diagnosis). Worth mentioning is that this oldest member of the genus is also the most modified venationally.Published as part of RASNITSYN, ALEXANDR P., MAALOUF, MOUNIR, MAALOUF, RAMY & AZAR, DANY, 2022, New Serphitidae and Gallorommatidae (Insecta: Hymenoptera: Microprocta) in the Early Cretaceous Lebanese amber, pp. 120-136 in Palaeoentomology 5 (2) on pages 121-123, DOI: 10.11646/palaeoentomology.5.2.4, http://zenodo.org/record/653041
