Etymology. Vinson (1863) named this species for its occurrence in Madagascar.

Identification. Vinson’s 1863 description ( Vinson, 1863: 100–102) reports mostly the markings of this large (18mm total length) male spider. The description, which states “Aspect général. Allonge, fauve dore avec deux bandes allongées, brun fauve, sur les côtés, de corselet; une bande médiane moins prononcée sur l’abdomen” ( Vinson, 1863: 100), is consistent with the markings of other individuals of this species. Especially telling is “J’ai trouvé ce grand Olios le soir dans ma chambre à Tananarive” ( Vinson, 1863: 103): this species occurs in and around the city of Antananarivo and is likely to be found in buildings, as was Vinson’s specimen. The description and Vinson’s collection record leave no doubt of the identification of Olios madagascariensis Vinson with U. madagascariensis ( Vinson, 1863) . Lehtinen (1967: 272) examined males and females of this species. He quotes the following data: “ Uduba Simon 1880 , Acta Soc. Linn. Bordeaux 34, 343: Olios madagascariensis Vinson 1863 , Aran. Reun. Mauric. Madag., 100 from Madagascar (male? type Paris; female described by Simon 1906: Paris).” He also contributed figures, including an unmistakable female epigynum, as his figures 81 and 84.

Remarks. This large, ecribellate species comprises populations in the central highlands with several records near Antananarivo as well as populations in the west and southwest of the island. Males are alike in the form of the TA3, TA2 and MA though there is variation in the outline of the tegulum. All females have the epigynal median lobe placed anteriorly and the lateral lobes fused posteriorly but the posterior shape of the ML varies even within populations ( Figs. 69 A–G View FIGURE ). All except the remarkable female from the Réserve Forestière Beanka in Mahajanga Province ( Fig. 69 G View FIGURE ) have the anterior margin of the ML truncate. Geography and variation are further discussed at the end of the description. Because of this degree of variation, we have lumped individuals with a variety of epigynal forms into the single species U. madagascariensis ( Vinson, 1863) .

Diagnosis. Uduba madagascariensis are an Unclassified species ( Map 21 View MAP ), which is ecribellate ( Fig. 20 E View FIGURE ). Males of U. madagascariensis ( Vinson, 1863) can be distinguished from those of other ecribellate Uduba by the form of the palp ( Figs. 29 C View FIGURE , 51 A–C View FIGURE ): the MA is small, transverse and with a small, prolateral point ( Fig. 52 D View FIGURE ), the TA3 forms a short hook ( Fig. 51 B View FIGURE ), the TA2 is sclerotized and partially occludes the TA3 ( Figs. 29 C View FIGURE , 51 A View FIGURE ): it is erect and bifid apically with the proapical element longer ( Figs. 52 A–F View FIGURE ). The females can be distinguished from those of other ecribellate Uduba by having an epigynum with an anterior median lobe and the lateral lobes fused posteriorly ( Figs. 68 A View FIGURE , 69 A–G View FIGURE ); in most specimens no atrium is visible (or rarely visible) and the copulatory openings are hidden or nearly hidden at the sides of the ML ( Figs. 68 A–D View FIGURE ).

A male from Toliara Province has the retroapical corner of the tegulum that makes a right angle, whereas in males from Antananarivo and Fianarantsoa Provinces the retroapical corner of the tegulum is smoothly convex ( Figs. 51 B View FIGURE , 52 A–F View FIGURE ).

In these specimens the posterior margin of the ML extends 0.20 to 0.40 of the distance to posterior margin of plate, the ratio of ML length / ML width is 1.38–1.61 and the ratio of ML length / epigynum length is 0.29–0.38. Individuals from Toliara Province also have the atrium completely hidden beneath the ML (Analavelona) and the ML oval to wider anteriorly ( Figs. 69 C–F View FIGURE ). A female from Réserve Forestière Beanka in Mahajanga Province (CASENT9042529) has the most distinct epigynum ( Fig. 69 G View FIGURE ): the atrium is visible at the sides of and also posteriad of the ML and both the anterior and posterior ends of the ML taper and become narrow, with no clear margins. In this individual the ML length is 1.17 times the ML width. The vulva length / width varies slightly ( Figs. 68 B–D View FIGURE , 69 B View FIGURE , 80 C View FIGURE ).

Natural history. This remarkable, ecribellate species occurs in native forest on the plateau, dry forests in the west and southwest, in Uapaca forest and even in disturbed areas near the large city of Antananarivo. Uduba madagascariensis ( Vinson, 1863) make no use of cribellate silk but create silk-lined burrows: at Ambohimanga specimens were collected “from short burrows surmounted by short turrets of woven grass, mostly on steep banks.” Males wander ( Figs. 1 F View FIGURE , 2 E View FIGURE ). Adult female individuals of the western populations from Réserve Forestière Beanka and Forêt Classée d’Analavelona were collected in pitfall traps, suggesting that these ecribellate spiders may occasionally wander even as adult females.

Distribution. Typical individuals of Uduba madagascariensis are known from Madagascar in Antananarivo and Fianarantsoa Provinces, on the east central part of the central plateau. Populations of U. madagascariensis that may have distinct genitalia occur on the western side of the escarpment in southwestern Madagascar, from Mahajanga and Toliara Provinces (Maps 4, 21).
