Melolonthinae; illustration; Leucopholini; female; Dedalopterus; Yunnan; xuhaoi; China. taxonomy; Introduction The genus Genus Dedalopterus Sabatinelli & Pontuale, 1998 currently comprises 10 valid species distributed in China, India, and Indochina (Bezdék, 2016; Bunalski, 2001; Moser, 1908; Pham et al., 2024; Sabatinelli & Pontuale, 1998; Xu et al., 2008; Zhang, 1990, 2002; Zidek & Krajcik, 2007). Of China, seven species have been known so far: - Dedalopterus fencli Zidek & Krajcik, 2007 (Guangdong province); - D. fujianensis (Zhang, 1990) (Fujian province); - D. intermedius (Zhang, 1990) (Yunnan province); - D. hainanensis Zhang, 2002 (Hainan province); - D. itohi Sabatinelli & Pontuale, 1998 (Sichuan province); - D. melanodiscus (Zhang, 1990) (Guizhou province); - D. signatus (Moser, 1908) (Yunnan province). In this paper, I am going to describe a new species of this genus from western Yunnan under the name of D. xuhaoi. In addition, a topotype of Dedalopterus intermedius (Zhang, 1990) is illustrated for comparison with the new species. All materials examined in this study are deposited in the Mianyang Normal University, Mianyang, China (MYNU). Data are provided verbatim for type specimens, using the following symbols: / = different lines; // = different labels.

Reviewer : Denis Keith (France) - http://zoobank.org/C922B63D-33 1E-44BF-B386-9A 70AEOSCA28 Received: 03/04/2024 — Revised: 06/04/2024 — Accepted: 06/04/2024 Remarks. — Dedalopterus intermedius was originally described by Zhang (1990) in the genus Malaisius, and transferred to Dedalopterus by Sabatinelli & Pontuale (1998). This species was recorded from Yunlong county (Caojian: alt. 2600 m) in northwestern Yunnan (Zhang, 1990) and Tengchong (Datang, alt. 1850 m) by Xu et. al (2008). In this study, several specimens from the type locality (Caojian: alt. 2500 m) were examined and the female is illustrated for the first time. The female exhibits distinct differences from the male as follows (Fig. 1 & 23): body plump, color darker; antennal club shorter; protibia wider, second protibial tooth longer and wider, basal tooth distinct; tarsus generally shorter; apex of mesotibia and metatibia wider. Antennal club slightly shorter than antennomeres 1-7 combined. Dedalopterus xuhaoi sp. n. (i AHERN) (Fig. 4-6, 10-12 & 19-22) ZooBank: https://zoobank.org/ESF48082-676E-48FC-B6EE4E88A 6EF4334 Holotype, 3 (MYNU): CHINA: Yunnan / Baoshan, Longling County / Xiangda Town, alt. 1700 m / V-VI.2021, local leg. // HOLOTYPE // Dedalopterus xuhaoi / F.-L. Wang det. 2024. Description of holotype (Fig. 4-6, 10-12 & 19-22) General appearance. — Body length: 20.1 mm, width: 9.1 mm. Body elongate ovoid, moderately convex in profile (Fig. 6). Color. — Whole body color brown; head, antenna, posterior margin of pronotum, scutellum, sutural costa, apex of tibias, joint of legs and claws darker. Body surface with white or grayish yellow oval, imbricating scales and narrow, acicular setae (Fig. 4). Head (Fig. 10). — Clypeus wide semicircular, 2.67 times as wide as long, anterior margin weakly reflexed; surface with spare, large punctures, with dense grayish yellow oval, imbricating scales. Fronto- clypeal suture complete, slightly concave-forward. Compound eyes comparatively large, interocular distance 0.62 times as wide as the maximum transverse width of head. Frons with an inverted triangular depression from fronto-clypeal suture to disc, surface rather sparely This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

Antenna with 10 antennomeres, antennal club composed of 3 antennomeres, 2.8 times longer than antennomeres 1—7 combined. The last joint of maxillar palpi expanded. Pronotum (Fig. 11). — Wide trapezoid, margins without marginal line. Lateral margin convergent in the middle, slightly flat, anterior half straight, posterior half incurved. Anterior margin deeply depressed before anterior angles. Anterior angles widely rounded, slightly flat; posterior angles acute, slightly prolonged, apex sharp. Surface sparely, shallowly punctate; with dense white oval, imbricating scales on the middle longitudinal area; with white oval, imbricating scales on posterior margin between scutellum and posterior angle, also with same scales on the depressed area of the anterior margin near the anterior angles; with dense, overlapped smaller, narrow, acicular yellow scales on the area around posterior angles; disc sparely with grayish yellow oval, imbricating scales; sparely with yellow setae on the anterior area of side. Scutellum. — Apex corner rounded, with several white or yellow narrow scales; disc sparely with grayish yellow oval, imbricating scales. Elytra (Fig. 4). — With five principal costae and five wide principal intervals, principal costae II and III composed of three narrow secondary costae and two narrow secondary intervals. Vestiture of principal interval I-III composed of dense white oval, imbricating scales, principal interval VI sparely with smaller yellow oval, imbricating scales, principal interval V densely with longer yellow setae, and yellow oval, imbricating scales near costa 5 (Fig. 14). White scales on principal interval I reaching the anterior margin and posterior angles, on principal interval II reaching the anterior margin but truncated before the lateral margin, and on principal interval II starting from humeral umbones and truncated before the lateral margin. Two narrow secondary intervals on principal costae II and III with white or yellow oval, imbricating scales. Pygidium (Fig. 12). — Weakly convex in profile, surface with dense grayish yellow acicular setae. Abdominal ventrites (Fig. 5). — With moderately dense grayish yellow oval, imbricating scales, sparer on the middle. Legs. — Protibia tridentate, terminal tooth slightly prolonged, basal tooth extremely weak; apex of mesotibia and metatibia slightly widened, surface with spare grayish yellow oval, imbricating scales. Tarsi slender and long. Genitalia. — As in Fig. 19-22. Differential diagnosis. — Depending on the shape of male genitalia (Bunalski, 2001; Pham ef al., 2024; Sabatinelli & Pontuale, 1998; Zhang, 1990, 2002; Zidek & Krajcik, 2007), Dedalopterus xuhaoi sp. n. (type-locality: Xiangda town) is closely similar to D. intermedius (type-locality: Caojian town, about 200 km from Xiangda county). We can distinguish D. xuhaoi sp. n. from D. intermedius by: 1 - clypeus and frons with large, oval, imbricating scales, the last joint of maxillar palpi expanded (Fig. 2, 5, 7 & 10; clypeus and frons with narrow, acicular setae, the last joint of maxillar palpi elongate in D. intermedius), 2- disc of pronotum with large, oval, imbricating scales (Fig. 8 & 11; disc of pronotum with narrow, acicular setae in D. intermedius); 3 - apex of pygidium broadly rounded, surface with dense scales (Fig. 9 & 12; apex of pygidium thinly rounded, surface with moderately dense setae in D. intermedius), 4 - scutellum with oval, imbricating scales (Fig. 1 & 4; with narrow, acicular setae in D. intermedius), 5 - principal interval V of elytra both with white oval, imbricating scales and yellow narrow, acicular setae (Fig. 13 & 14; only with yellow narrow, acicular setae in D. intermedius); 6 - basal part of left parameres narrower, apex part becoming widened distinctly (Fig. 17 & 21; left parameres almost parallel, only slightly widened at apex in D. intermedius). Etymology. — The new species is named after my friend Dr. Hao Xu (MYNU), who provided valuable taxonomic articles for this study. Distribution. — Xiangda town, Longling county, western Yunnan, China (Fig. 24). Acknowledgments I am grateful to Dr. Hao Xu (MYNU) for sharing taxonomic articles of the genus Dedalopterus.
