Flavonuncia ubicki n. sp. (Figs 6-9; 23B, G, L) urn:lsid:zoobank.org:act: 98ACD478-4293-4143-9AA2-62CC86C937CF TYPE MATERIAL. — Holotype. Madagascar • ♂; Toamasina, Analamay-Mantadia, Ambaroharanana; Elev. 1012 m; 18°48’14”S, 48°24’18”E; coll. Malagasy ant team; 19-21.XII.2012; sifted litter, rainforest, collection code: BLF30324; CASTYPE 21649. Paratypes. Madagascar • 1 ♀; same data as for holotype; CASENT 9072045 • 1 ♂ SEM voucher; same data; MACN-Ar 45999 • 1♀; same data; MACN-Ar 46000. ETYMOLOGY. — Patronymic in honor of the former CAS arachnologist and friend Darrell Ubick, in recognition of his contribution to the advances of arachnology. COMPARATIVE DIAGNOSIS. — Robust, long legged Flavonuncia species, differing from all known Flavonuncia species by the pair of apical tubercles present on the top of the ocularium. The penis is similar to Flavonuncia pupilla. DISTRIBUTION (Fig. 1). — Known only from the type locality. DESCRIPTION Male (CASTYPE 21649) Measurements. See Table 1. Dorsum (Figs 6A, C; 7A, B). Outline hourglass-shaped of Eta (η) type. Ocularium conical, with a pair of apical tubercles, eyes located on the top of the ocularium. Mesotergal scutum without tubercles or apophyses. Carapace smaller than mesotergum, mesotergal areas not clearly defined, areas I-II with a row of two small setiferous granules, area III with three, area IV with eight, the posterior border with a row of 15 granules. Free tergites bearing a row of granules on each tergite. Venter (Figs 6E; 7C, D). Coxae ventral surface covered by setae; coxa I bearing 8-9 granules, almost all ventral surface covered by cerotegument, except by the proximal coxa II-III; proximal coxa II with a remarkable tubercle with three basal setae and one tubercle with subdistal setae; coxa III with three tubercles, small bridge present, spiracles not visible. Sternum straight with a drop shape base. Chelicerae (Fig. 8A, B). Basicheliceritae bearing a small tubercle on dorso-distal surface, cheliceral hand bearing seven ectal small tubercles with subdistal setae, two mesal small granules, and one mesal tubercle with subdistal setae. Pedipalps (Fig. 8C, D). With one ventral and two small dorsal tubercles, femur bearing a ventral row of small tubercles and two distal acute tubercles on the distal surface, patella with four mesal tubercles, tibia ventral surface bearing sparse small tubercles, with a medial and 2-3 apical acute tubercles with subdistal setae, tarsus bearing four ectal and five mesal tubercles with setae. Legs (Fig. 8 E-H). Astragalus longer than calcaneus. Tarsal count: 3-6-4-4. Genitalia (Figs 9; 23B, G, L). Penis proportionally larger than other species of Flavonuncia. Capsula interna longer than the ventral plate, ventral view with a cleft separating the capsula interna into two halves, apical portion of ventral plate narrow arch-shaped, with upper and lower macrosetae not aligned in dorsal view. Ventral view, with a group of three macrosetae. Distal capsula interna with a complex structure ending in a thin free stylus. Ventral distal part of the capsula interna bearing a hexagonal process. Female (CASENT 9072045) (Fig. 6B, D, F) Similar to male, presenting dimorphism in the body coloration, females having a dark brown opisthosoma while the males are yellowish with brown stripes. Pedipalps larger in males.
