Abstract

<i>Holzezus</i> Krivokhatsky, 1992 DZdzḇx <p> <i>Holzezus</i> Krivokhatsky, 1992: 407. <b>Type species:</b> <i>Holzezus compactus</i> Krivokhatsky, 1992, by original designation.</p> <p> <b>Diagnosis. Adult:</b> Body pale yellow to yellowish brown, with many dark brown markings. Vertex obviously raised and rounded, covered with some short pale setae. Ocular rim setae present, pale and needle-like. Pronotum laterally with pale hairy setae. Mesoscutellum naked, without setae. Tibial spurs short, spinelike, shorter than tarsomere 1; tarsomere 5 nearly as long as entire length of tarsomeres 2–4. Forewing RP origin distad MP and CuA fork; five to seven presectoral crossveins present. Hindwing shorter than forewing; four to five presectoral crossveins present; pilula axillaris absent. Abdomen shorter than hindwing length; male terga 6–7 each with a pair of hairy pencil-like structures (Fig. 3C); female sternum 7 with a pair of digital projections (weakly developed in <i>H. pamiricus</i>) (Fig. 3I). Male gonocoxites 9 small, shaped as a pair of thick hook-like structure; gonocoxites 11 arched in ventral view, broad in lateral view; ectoproct without posteroventral lobe. Female gonocoxites 8 slender digitiform, only one paired; gonocoxites 9 protruded with a few strong curved long digging setae.</p> <p> <b>Distribution.</b> China, Iran, Mongolia, Tajikistan, Turkmenistan, Uzbekistan.</p> <p> <b>Remarks.</b> This genus is similar to <i>Iranoleon</i> by having similar male genitalia (Hölzel 1968; 1972). However, the ocular rim setae of <i>Holzezus</i> are present, while they are absent in <i>Iranoleon</i>; the wings of <i>Holzezus</i> are narrower than <i>Iranoleon</i>; and the female digging setae of <i>Holzezus</i> are longer and curved. Besides, some species of <i>Iranoleon</i> has three pairs of hairy pencil-like structures (terga 5–7), e.g., <i>I. arabicus</i> Hölzel, 1982, which can also be distinguished from <i>Holzezus</i>.</p>Published as part of <i>Zheng, Yuchen, Liu, Zijun, Zhang, Dong & Liu, Xingyue, 2024, Taxonomic notes on two antlion genera Holzezus Krivokhatsky, 1992 and Subgulina Krivokhatsky, 1996 (Neuroptera: Myrmeleontidae: Myrmecaelurini) from China, pp. 256-268 in Zootaxa 5403 (2)</i> on page 258, DOI: 10.11646/zootaxa.5403.2.4, <a href="http://zenodo.org/record/10562004">http://zenodo.org/record/10562004</a&gt
