Uduba funerea Simon 1906 View in CoL , holotype female from Suberbieville , Madagascar, specimen AR231 from Muséum National d’Histoire Naturelle , Paris, examined. Species status restored.

Uduba dahli View in CoL : Lehtinen, 1967 [misidentification, not dahli Simon 1903 View in CoL ; Synonymy rejected]

Identification. We have examined the holotype of Uduba funerea Simon 1906 View in CoL from Suberbieville , Madagascar. See discussion below under Distribution for more information on the location of Suberbieville .

Remarks. Lehtinen accepted Simon’s (1903) use of Uduba dahli as a replacement name for the preoccupied Marussenca madagascariensis Dahl 1901b . Lehtinen (1967: 272) also proposed as a new synonym U. funerea Simon 1906 equal to U. dahli Simon 1903 . Whereas the females of each species are similar to each other, that of U. funerea has an entire cribellum and that of U. dahli ( Marussenca madagascariensis Dahl 1901b ) has a divided cribellum ( Fig. 34 C View FIGURE ). We consider this difference in cribellar form to be species diagnostic for our revision and therefore we reject the synonymy of U. funerea Simon 1906 with U. dahli Simon 1903 .

Diagnosis. Uduba funerea belong to Group I.c, the Uduba funerea group ( Map 15 View MAP ) of Group I, the Epigynal atrium group. They are cribellate, with cribellum entire. Males are unknown. The females of Uduba funerea can be distinguished from those of other Uduba having an entire cribellum and an epigynal plate with median lobe surrounded by depressed atrium ( Fig. 79 C View FIGURE ); the entire cribellum is unlike U. dahli Simon 1903 but like Uduba halabe . Uduba funerea can be distinguished from U. halabe by having the copulatory openings hidden beneath the lateral margins of the atrium ( Fig. 79 E View FIGURE ); in U. halabe the CO are located centrally beneath the epigynal median lobe ( Figs. 74 C, F View FIGURE ).

Description. Female (holotype). We made a detailed examination of the female holotype but upon returning the specimens to the Muséum National d’Histoire Naturelle in Paris in the 1990’s we kept only a few somatic illustrations and detailed illustrations and measurements of the female genitalia. We are therefore unable to provide details of measurements and spination for the holotype and can only describe and illustrate the female genitalia in detail. Cribellum entire. Female genitalia (Holotype) Epigynal plate with median lobe surrounded by depressed atrium ( Fig. 79 D View FIGURE ), plate width 1.49 times length; atrium sides concave, atrium wide, width 1.80 times atrium length; epigynum length 1.90 times atrium length, atrium width 0.58 times epigynum width; atrium width at side of ML 1.88 times ML width; atrium and median lobe base arise anteriad of epigastric groove ( Fig. 79 C View FIGURE ), atrium base at 0.20 of epigynal plate length, median lobe narrow, slightly wider at base, median lobe length 2.70 times width, ML extends to apex of atrium, ML length 0.60 times epigynal length; lateral lobes narrow, atrium width 4.50 times LL width; copulatory openings hidden beneath lateral sides of atrium, distance between CO 0.62 width of epigynal plate, CO distance from epigastric furrow 0.50 times epigynum length. Vulva ( Figs. 79 D, E View FIGURE ) with spermathecal ducts asymmetrical, on left making three broad, transverse curves, on right three opposed loops, vulva length 0.65 times width, vulva width 4.50 times distance between fertilization ducts.

Variation. Unknown: only the female holotype of Uduba funerea Simon 1906 is known.

M aterial examined. Only the holotype female, specimen AR231 at MNHN, Paris , from “Suberbieville”, Madagascar .

Natural history. Unknown. The female has an entire cribellum, suggesting use of cribellate silk.

Distribution. Uduba funerea Simon 1906 is known only from the type locality, “Suberbieville”, in Majunga Province, Madagascar, approximately 240 km NNW of Antananarivo (Maps 2, 15). Gold mining has been conducted in this region since the late 1800’s. The town, formerly called Suberbieville after the industrialist who exploited the gold of the Ikopa River, is now known as Maevatanana and is located on the right bank of the Ikopa River, south of its confluence with the Betsiboka River. It is located at about 70m elevation at approximately S16°57′00ʺ, E46°50′00ʺ and is the main stop of the RN 4, the road connecting Antananarivo to Mahajanga.
