description: <i>Indonemoura clavata</i> sp. n. (Figs. 20-24) <b>Material examined.</b> Holotype &amp;male; from Vietnam, Vinh Phu Province, Tam Dao, 800-1000 m, 19 May-13 June 1995, H. Malicky (PMSL). Additional material: Vietnam: Type locality, 19 May-13 June 1995, H. Malicky, 15&amp;female; (PMSL). Vinh Phu Province, Tam Dao, 23 March 1995, 1&amp;female; (ZMB). <b>Adult habitus.</b> General color dark brown. Head and wings dark brown; pronotum slightly paler with obscure rugosities. Legs, palpi and antennae uniformly dark brown. <b>Male.</b> Forewing length 6.5 mm. Epiproct narrowed near midlength and slightly expanded subapically, apex with a shallow notch in dorsal aspect (Fig. 20); ventrolateral aspect greatly expanded and armed along most of length with thick setal spines (Fig. 21). Mesal lobe of paraprocts sharply bent near base and club shaped; outer lobe slender, heavily sclerotized, appressed to mesal lobe near apex, bearing a subapical knob and a bifurcate tip; inner lobe needlelike (Figs. 22-23). Tergum 10 bearing a small median patch of sensilla; tergum 9 with a sparse patch of sensilla along posterior margin. Vesicle narrow, only slightly wider subapically (Fig. 22); hypoproct slightly constricted near midlength between apex and posterior margin of sternum 9. <b>Putative female.</b> Forewing length 8 mm. Subgenital plate scarcely produced beyond hind margin of sternum 8; posterior margin with a slight median emargination (Fig. 24). Oval paragenital plates distinct. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name refers to the club shaped mesal paraproct lobe. <b>Diagnosis.</b> The epiproct of this species is similar to that of several species including <i>I. auriformis</i> Li &amp; Yang (Li &amp; Yang 2008a), <i>I. baishanzuensis</i> Li &amp; Yang, <i>I. fujianensis</i> Li &amp; Yang, <i>I. guangdongensis</i> Li &amp; Yang, <i>I. hubeiensis</i> Yang &amp;Yang, <i>I. macrolamellata</i> (Wu) and <i>I. yangi</i> Li &amp; Yang (Li &amp; Yang 2006; 2008c) and <i>I. tricantha</i> (described below). We formally recognize these species, distinguished on the basis of paraproct structures, particularly those of the outer lobes, as members of the <i>Fujianensis</i> complex. Within the complex only <i>I. clavata</i> has the mesal paraproct lobe club shaped and the outer lobe terminating in a pair of short, almost equally sized spines. Chinese members of the complex, except <i>I. auriformis,</i> are included in keys developed by Li &amp; Yang (2006; 2008c).This new species and <i>I. tricantha</i>, the only regional members of the complex, are distinct from other Southeast Asian <i>Indonemoura</i> in having the ventral epiproct sclerite greatly produced into a wide, semicircular structure (Fig. 21), typical of all species in the <i>I. fujianensis</i> complex.
