1.2.11. Curtonotum rinhatinana View in CoL species-group
Species included: 1 (Afrotropical; confined to Madagascar).
Autapomorphy: Sclerotized sperm pump present (37). Curtonotum rinhatinana has a number of unique characters. Although similar in external characters to other species of the genus the bizarre structure of the basiphallus and the presence of a large sclerotised sperm pump, precludes it from any direct association and it is here tentatively ascribed to a species-group of its own. Its systematic position can only be fully assessed as part of a more extensive molecular study.
Systematics

Diagnosis
Small to medium-sized (1.9–7.7 mm), distinctly robust, hunchbacked flies. Greyish to brown, often with vitae on thorax and pigment patterns on abdomen. Head: compound eye probably green-brown iridescent in living examples, in profile gently and evenly rounded anteriorly, slightly triangularly produced posteriorly; 2 pairs of long, prominent fronto-orbital setae, the anterior pair proclinate, the posterior pair reclinate, with a minute reclinate seta positioned between them, close to base of posterior orbital setae socket; frons wide in both sexes. Arista plumose with long dorsal and ventral branches. Thorax: mesonotum moderately convex, very slightly flattened behind head, with multiple rows of regular, short, black, overlapping setulae; 1 pair of strong dorsocentral setae and one pair of acrostichal setae; anepisternum with 2–3 long setae and some short setulae; one very long katepisternal seta accompanied by a short dorsal one. Scutellum: disk entirely clothed in setulae, with 2 pairs of strong marginal setae. Wing: greyish to grey-brown infuscate, dm–cu crossvein usually markedly infuscate; costa (c) with humeral and subcostal breaks and subcosta complete, with a variable number of prominent costal spines beyond R 1 longer and stronger than adjacent vestiture. Legs: all tibiae with preapical dorsal setae; fore femur with row of short, but strong spinules posteroventrally along distal ½ or ⅓, variable in number. Abdomen: long, cylindrical, telescopic, generally pale in colour with brown maculae or T-shaped lateral markings. Phallapodeme, basiphallus and distiphallus fused or articulated and asymmetrical, forming C-shaped structure. Female abdomen with tubular ovipositor, cerci sometimes fused, with spine-like setae or setulae. Spermathecae flattened, short and obclavate with a folded or rugose surface, or long, tubular and studded with protuberances.
