FAIDITUS KEYSERLING, 1884 View in CoL View at ENA
Type – F. ecaudatus Keyserling, 1884 , designated by Petrunkevitch (1928), not examined.
Synonyms: Bellinda Keyserling, 1884 – type Theridion cancellatum Hentz, 1850 [= Bellinda cancellata ], not examined, syn. nov. Bellinda appears in the same publication as Faiditus . Usage may suggest priority of Faiditus , as Bellinda is only mentioned in Keyserling’s publication, but Petrunkevitch (1928) includes Faiditus in his Systema Aranearum.
Faiditus View in CoL is removed from synonymy of Argyrodes View in CoL , contra Levi & Levi (1962: 21). F. ecaudatus Keyserling, 1884 View in CoL , and all other species attributed to the ‘ A. cancellatus ’ and ‘ A. cordillera ’ groups of Exline & Levi (1962) and Zhu (1998) are explicitly transferred to Faiditus View in CoL and the following new combinations established:

Diagnosis: Faiditus here differs from other argyrodines (based on F. cf. chickeringi ) by the following putative synapomorphies: copulatory bursa anterior margin medially acute (6) a strongly hooked TTA distal tip (85, Fig. 48A, B View Figure 48 ), abdomen with paired (or multiple) humps (142, Fig. 94C View Figure 94 , also in some Neosphintharus ( Fig. 57F View Figure 57 ), E hidden by TTA ( Fig. 48B View Figure 48 ), and details of male cephalic modification (a shallow clypeal groove with a dense field of setae, Fig. 48C, D View Figure 48 ). All known Faiditus are kleptoparasitic and, as in Argyrodes , males are often larger than females ( Exline & Levi, 1962). At least details of cephalic modifications appear universal in Faiditus (see e.g. Exline & Levi, 1962; Zhu, 1998). Medially acute anterior copulatory bursa margin, hooked TTA distal tip, and E hidden by TTA were confirmed in other Faiditus examined in detail: F. americanus , F. amplifrons , F. cancellatus , F. cf. caudatus , F. spinosus and F. ululans . Abdomen humps were lacking only in F. ululans .
The synonymy of Bellinda with Faiditus was corroborated with examination of nontype specimens of the Bellinda generotype, F. cancellatus .
