description: <i>Asiobaccha marissae</i> Mengual sp. nov. (Figures 1, 7a, b, e) <i>Asiobaccha</i> n. sp. of Mengual 2015: 398 (DNA voucher ZFMK_XM127). <i>Description</i> <i>Male: Head.</i> Face with distinct round facial tubercle, yellow, yellow pilose, yellow pollinose except shiny medially on tubercle; gena yellow; lunule yellow; frons yellow, somewhat darker dorsally, yellow pilose, densely yellow pollinose laterally and dorsally, shiny basomedially; antenna yellow, yellow pilose; arista brown, yellow basally, bare; antennal base with lateral lobular expansions on each side; vertical triangle narrow, black; eye bare; occiput black, grey pollinose, yellow pilose with some brownish/darker pile on dorsal 1/4 (Figures 1, 7e). <i>Thorax.</i> Scutum yellow anterior to transverse suture, dark brown or black posterior to suture, yellow pilose with some brown pile on posterior 1/2, brown pollinose on dark areas; without mesonotal fringe; postpronotum yellow, bare; postalar callus yellow; scutellum yellow, yellow pilose, subscutellar fringe present with yellow pile (Figure 7a, b). Pleuron yellow with a vertical black marking going from dorsomedial anepimeron to mesocoxa; anatergum, metaepimeron and metaepisternum black; yellow pilose and yellow pollinose; anterior anepisternum pilose on anterodorsal quarter; metaepisternum pilose ventrad to spiracle; metasternum bare; calypter small, reduced, yellow; plumula absent; halter pedicel yellow, capitulum darker; posterior spiracular fringes yellow. <i>Wing</i>: alula narrow, narrower than costal cell, bare; wing hyaline, yellow anteriorly, stigma a bit darker, extensively microtrichose except costal cell bare on basal 1/6 or less, cell R bare on basal 1/3, cell BM bare on basal 1/2, and cell CuP and anal lobe bare basally. <i>Legs</i>: entirely yellow, except meso- and metacoxa black and metafemur yellow with a subapical dark annulus. <i>Abdomen.</i> Petiolate, unmargined. Tergum 1 yellow, yellow pilose; tergum 2 yellow with a medial, diffuse brown macula, and a diffuse dark fascia on posterior margin; tergum 3 yellow with a basal, diffuse brown fascia on anterior margin and a black fascia on posterior margin emarginated medially; tergum 4 black with a basal, broad, yellow fascia on anterior 3/5 deeply emarginated posteromedially; tergum 5 yellow with brown lateral margins (Figures 1, 7a); sterna yellow, and sterna 3 and 4 with a posterior, black fascia. <i>Female.</i> Similar to male except for normal sexual dimorphism and as follows: frons yellow on ventral 1/5, black on dorsal 4/5, densely yellow pollinose except basal 1/4. <i>Variation.</i> The dark annulus of the metafemur is not well-defined in some specimens. The extension of the black posterior area on scutum is variable, as well as the extension of the posterior black fascia on terga 3 and 4. <i>Length (N = 4).</i> Body, 9.5 <i>–</i> 13.0 (11.9) mm; wing, 9.0 <i>–</i> 12.0 (11.3) mm. <i>Geographical distribution</i> Species known only from Sulawesi. <i>Genetics</i> The GenBank accession numbers for this species are: 28S gene (KM 270823, specimen ZFMK _ XM127), 18S gene (KM 270771, specimen ZFMK _ XM127), COI gene (KM 270854, specimen ZFMK _ XM127). <i>Etymology</i> This species is named after my wife, Marissa Sendra i Peiró, in her honour. This species is the most colourful, radiant and distinguished of <i>Asiobaccha</i>, just as Marissa is for my life. The name is to be treated as a noun in the genitive case. <i>Differential diagnosis</i> Species with a narrow alula, without mesonotal fringe, tergum 4 with an anterior, broad yellow fascia and scutellum yellow. <i>Asiobaccha marissae</i> has unique characteristics, such as the abdominal colouration and the lobular expansions on each side at the antennal base. This species is similar to <i>Asiobaccha notofasciata</i> but the latter has a well-developed mesonotal fringe, alula broad and no modified antennal base. <i>Asiobaccha marissae</i> differs from other species without mesonotal fringe by the yellow fascia on tergum 4 and the antennal base expansions. <i>Type locality</i> Indonesia: Southeast Sulawesi Province, North Kolaka Regency, Rante Angin, east of Tinukari, 03°27.7 <i>ʹ</i> S, 121°5.1 <i>ʹ</i> E. <i>Material examined</i> <i>Type material.</i> <i>Holotype</i>, male, deposited in the Museum Zoologicum Bogoriense (Bogor, Java, Indonesia) and labelled: <i>‘</i> INDONESIA: SE SULA- // WESI, North Kolaka // Rante Angin, // east of Tinukari <i>’</i>, <i>‘</i> 03°27.7 <i>’</i> S 121°5.1 <i>’</i> E // 23.VI.2010 // L.S.
