Tetraglossula franki

description: Tetraglossula franki (Friese, 1908)
(Figures 6, 7, 16 C, 17H, 18F)
Bicolletes franki Friese, 1908, 12. Type data: holotype ZMB ♂ (examined); type locality: Argentina, Buenos Aires. Tetraglossula franki; new generic combination.
Diagnosis. Distinguished for the large body size (> 11 mm), the dark metasoma, and the pale to whitish pubescence on mesosoma. This is also the only species in which punctation on the disc of scutum of females and males is dense to moderately dense (<1–2 pd).
Comments: this species was described more than a century ago, and the few times the species name ‘franki’ has been used was as citations in taxonomic catalogues as “ Bicolletes franki ” (e.g., Moure et al. 1999, 2012). Ogloblin applied the name ‘franki’ to a specimen (Fig. 7) collected in the province of Buenos Aires (therefore matching the type-locality) and used this name in combination with Tetraglossula in the handwritten determination label (Fig. 7 D), but this was never reported by Ogloblin in his publications. So far, the only known specimens of this species are the holotype male deposited in Berlin (ZMB) and the female deposited in the La Plata collection (MLP) reported and described here for the first time. Description of female. Mensuration (in mm): body length c. 10.3; forewing and hindwing lengths 7.9, 6.0; diameter of the median ocellus 0.24; ocellocular distance (shortest distance between lateral ocellus and compound eye) 0.60; interocellar distance (shortest distance between lateral ocelli): 0.56; upper & lower interocular distance (shortest distance between inner orbits of compound eyes, above & below level of emargination, respectively): 2.15, 2.24; maximum interocular distance (greatest distance between inner orbits of compound eyes at level of emargination): 2.32; interalveolar distance (shortest distance between antennal foramina): 0.53; length of scape, pedicel, F1, F2, and F3: 0.92, 0.19, 0.21 0.13, 0.15, width of F3: 0.22. Intertegular distance: 2.54, length of scutum, scutellum, metanotum, and anterior horizontal surface of metapostnotum: 2.10, 0.82, 0.41, 0.30. Length of metasoma and maximum width (T3): 3.69, 1.25; maximum width of T1 (apical margin): 3.26. Punctation coarse and dense on scutum (<1–2 pd) sparser on the portion between parapsidial and the median scutal lines (median line deeply impressed as a furrow); on T1 fine and sparse (1.5–4 pd) intermixed with minute punctures, impunctate band on marginal area of narrower than one flagellar diameter. Pubescence mostly light pale yellow, whitish ventrally on mesosoma, brighter yellow on ventral metasomal scopa (S2–S5), brown on hind tibia close to basitibial plate and on posterior margin.
Male genitalia and hidden sterna: not examined.
Distribution (Fig. 19): ARGENTINA: Buenos Aires [ZMB:1, MLP:1].
