The genus Macroocula Panfilov in Egypt, with two new species (Hymenoptera: Bradynobaenidae: Apterogyninae)

Abstract

The genus Macroocula Panfilov in Egypt is reviewed. Seven species were previously recorded from Egypt: M. magna (Invrea, 1965), M. mahunkai Argaman, 1994, M. morawitzi (Radoszkowski, 1888), M. nigriventris (Invrea, 1960), M. nitida (Bischoff, 1920), M. savignyi (Klug, 1829) and M. sinaica (Invrea, 1963). Macroocula brothersi Gadallah & Soliman, sp. nov. (Egypt, Wadi Shab, Red Sea) and M. salehi Gadallah & Soliman, sp. nov. (Egypt, Wadi Shaghab, Aswan) are described and illustrated. The subspecies M. nitida nitida (Bischoff, 1920) and M. nitida patrizii (Invrea, 1932) are raised to species level. An illustrated key and a faunistic list of Macroocula species are given.

Three new species of the genus Macroocula Panfilov, 1954(Hymenoptera: Bradynobaenidae: Apterogyninae) from Saudi Arabia

“…silvioi Pagliano, 2002 in having a ventral protuberance on the hind trochanter, but it differs from them remarkably in the following: the protuberance on the hind trochanter is much smaller than that on the mid trochanter (protuberances on mid and hind trochanter are similar in size in M. ohli and M. silvioi); head and mesosoma ferruginous yellow, metasomal segments 2-6 brown (body uniformly pale yellow in M. ohli and bright yellow to almost white, with scattered black spots on mesoscutum and very slightly brownish tint on disc of T2 and T3, in M. silvioi). Moreover, the new species resembles the Egyptian M. brothersi Gadallah and Soliman, 2015 but strongly differs from it in the following: aedeagus as long as parameres, outer margin of parameres moderately concave (aedeagus about 0.5 times as long as parameres in M. brothersi, outer margin of parameres strongly concave, Figure 21); legs and forewing veins whitish (legs ferruginous yellow and forewing veins light brown to yellow in M. brothersi); first metasomal segment brownish (ferruginous yellow in M. brothersi); brachial cell as long as wide and 0.8 times as long as anterior vein of cubital cell (2.8 times as long as wide and 1.3 times as long as anterior vein of cubital cell in M. brothersi).…”

An illustrated key to the Saudi Arabian species of the genus Macroocula Panfilov, 1954, with the description of a new species and the previously unknown female of M. andreai Pagliano (Hymenoptera, Bradynobaenidae, Apterogyninae)

“…Eyes bulged, hemispherical, with its diameter about 4× distance between inner eye margin and antennal tubercle in male, and equal to distance between inner eye margin and antennal tubercle in female; distance between eye and occipital carina at most equal to eye diameter in female and by less than its own diameter in male; ocelli larger than or at least as large as flagellar diameter; hind trochanter without protuberance as that of mid trochanter in most Macroocula species, except for few Egyptian and Arabian species; posterior margin of metasomal tergites without fringe of setae, except for the Arabian species M. riyadha (Pagliano 2002, 2008, Gadallah et al 2014, 2015, Soliman et al 2016). …”

“…The genus Macroocula Panfilov, 1954 is considered one of the largest of the subfamily Apterogyninae (Hymenoptera, Bradynobaenidae), representing about 27 % of the total number of apterogynine species (Pagliano 2002, 2008, 2011, Gadallah et al 2014, 2015, Soliman et al 2016). Species are distributed in Africa and Asia, predominantly in the Afrotropical region (Pagliano 2002, 2008, 2011; Gadallah et al 2014; Soliman et al 2016).…”
