Odonaellus expansus Hu, Cao & Xing, 2025, sp. nov.

Odonaellus expansus sp. nov. Figs 13–16, 17–20, 21–28, 29–34 Description. Color pattern of anterior dorsum and face as in Figs 13 – 20. Male pronotum dark brown with irregular fuscous spots (Fig. 15); female pronotum yellowish brown, without spot (Fig. 19). Other external features as in generic description. Male genitalia. Male pygofer with one pair of sharp ventral processes arising caudally and a pair of tiny posteroventral process grown in dorsal inner surface (Figs 21, 22). Valve large (Fig. 23). Subgenital plate without macrosetae (Fig. 24). Aedeagal shaft auricular and subapical inner margin with a few small dentae; gonopore subapical (Figs 26, 27). Connective with arms shorter than stem (Fig. 25). Style curved; apical apophysis stout and subapically concave. (Fig. 28). Female pygofer with ventroposterior margin sharply incurved (Fig. 29). Female seventh sternum posterior margin concave, resulting in projection on both sides (Fig. 30). First valvula of ovipositor slightly curved, attenuate to apex, with indistinct scale-like sculpture ventrally (Figs 31, 32). Second valvula with small teeth near apex (Figs 33, 34). Measurement. Length (including tegmen): ♂, 5.4–5.7 mm; ♀, 5.8–6.5 mm. Type material. Holotype: • ♂, China: Guangxi Autonomous Region, Longzhou County, Nonggang; 22°25'21"N, 106°97'27"E; 4 May 2014, coll. Qu Wu (GUGC); paratypes: • 4 ♂♂ 5 ♀♀, Guangxi Autonomous Region, Longzhou County, Nonggang; 22°49'97"N, 106°97'49"E; 8 May 2012, coll. Zhiwei Fan, Hu Li; • 3 ♂♂, Guangxi Autonomous Region, Longzhou County, Nonggang; 22°52'66"N, 106°96'94"E; 4 May 2014, coll. Qu Wu (GUGC). Etymology. The new species name is Latin adjective expansus, “ expanded ”, which is in reference to the broadly expanded base of the aedeagal shaft. Remarks. This species agrees more closely with the subtribal diagnosis of Eremophlepsiina (Zahniser and Dietrich 2013) than does the type species of the genus. Unlike O. serratus, O. expansus has the male valve nearly as long as wide, the pygofer process ventrally arising, and the subgenital plate lacking macrosetae as in other Eremophlepsiina.
