Description: Male . Length : Body (PT), 16.3 mm ; wing (PT), 10.6 mm . Head : Black except lunule more reddish brown, sparsely white pollinose, yellow pilose; broadly dichoptic; antenna reddish brown; scape and pedicel black pilose; basoflagellomere light brown; arista yellow. Thorax : Pronotum yellow, yellow pilose; propleuron black anteriorly, yellow posteriorly, yellow pilose; scutum black except dull yellow marginally, sparsely grey pollinose with dark brown pollinose medial vitta, short yellow pilose; postalar callus yellow, yellow pilose; scutellum yellow, yellow pilose; pleuron mainly dull yellow, white pilose, dark on posterior antepisternum; calypter white; halter yellow. Legs: coxae and trochanters black, pale pilose; femora black except yellow on basal ¼, pale pilose on pale areas, black pilose on dark areas; pro and meso tibia black except apical ⅓ reddish brown, black pilose; metatibia yellow on basal ½, black apically, black pilose; pro and mesotarsi brownish black except apical tarsomere reddish, black pilose. Wing: Light brown anteriorly, extending posteriorly to vein R and R 4+5 and along veins, elsewhere hyaline, microtrichose except bare cell cup (anal), except for along its margins. Abdomen : Elongate, only very slightly petiolate, black; 1 st tergum golden pilose; 2 nd tergum mainly light brown pilose, except with apical margin broadly golden pilose and with a small apicomedial triangle patch of black pile; 3 rd tergum dull black pollinose except sparsely greyish white pollinose basolaterally, black pilose except white pilose basolateral and along lateral margin; 4 th tergum golden pilose; genitalia white pilose. Figs 4–6. Spheginobaccha pamela sp. n. Paratype ♂ (Madagascar): (4) habitus, dorsal view; (5) habitus, lateral view; (6) genitalia, lateral view. Holotype ♂ : SOUTH AFRICA : KwaZulu-Natal : Manguzi Forest Reserve , 26°59'32"S 32°43'25"E , 61 m , 13–17.xii.2010 , Malaise trap in indigenous sand forest, A. K. Kirk-Spriggs , specimen code BMSA(D) 30059 (deposited in BMSA ). Paratypes : 1♂ same data as holotype with specimen code BMSA(D) 30058 (deposited in USNM ) ; 1♂ KwaZulu-Natal : St. Lucia Estuary , 10.ii.1974 W.W. Middlekauf (deposited in CAS ) . Remarks:As noted in the key to species below, pamela is most similar related to guttula , but differs in abdominal coloration, the male genitalia and the shape of the antenna.
