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. Wing: 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. Legs: entirely yellow, except meso- and metacoxa black and metafemur yellow with a subapical dark annulus.   Figure 7.  Asiobaccha marissaeMengual sp. nov.a–b, e, paratype ♂. (a) Dorsal view; (b) lateral view; (e) frontal view.  Asiobaccha notofasciataThompson & Mengual sp. nov.c–d, f, ♂. (c) dorsal view; (d) lateral view; (f) frontal view. Scale bars: a–d = 2 mm; e, f = 1 mm.  Abdomen.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.  Female.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.  Variation.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.  Length (N = 4).Body, 9.5 –13.0 (11.9) mm; wing, 9.0 –12.0 (11.3) mm.   Geographical distribution Species known only from Sulawesi.   Genetics 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).    Etymology This species is named after my wife, Marissa Sendra i Peiró, in her honour. This species is the most colourful, radiant and distinguished of  Asiobaccha, just as Marissa is for my life. The name is to be treated as a noun in the genitive case.    Differential diagnosis Species with a narrow alula, without mesonotal fringe, tergum 4 with an anterior, broad yellow fascia and scutellum yellow.  Asiobaccha marissaehas unique characteristics, such as the abdominal colouration and the lobular expansions on each side at the antennal base. This species is similar to  Asiobaccha notofasciatabut the latter has a well-developed mesonotal fringe, alula broad and no modified antennal base.  Asiobaccha marissaediffers from other species without mesonotal fringe by the yellow fascia on tergum 4 and the antennal base expansions.     Typelocality   Indonesia: Southeast Sulawesi Province, North Kolaka Regency, Rante Angin, east of Tinukari, 03°27.7 ʹS, 121°5.1 ʹE.   Material examined  Type material.   Holotype, male, deposited in the Museum Zoologicum Bogoriense (Bogor, Java, Indonesia) and labelled: ‘ INDONESIA: SE SULA- // WESI, North Kolaka// Rante Angin, // east of Tinukari ’, ‘ 03°27.7 ’S 121°5.1 ’E//  23.VI.2010// L.S.
