Orchestina pavesiiformis Saaristo, 2007: 124 , figs. 16, 18, 20, 21 (male holotype from Israel: Jerusalem, 08.Jan.1989, G. Levy leg., deposited in HUJ 14220; same data, male paratype, 13.June.1990, deposited in MZT 3703; same data, female paratype, 03.May. 1989 in MZT 3704; same data, female paratype, 24. Apr.1991, deposited in HUJ 15326; same data, female paratype, 25.Mar.1988, deposited in HUJ 14184; all taken at night inside buildings; not examined).

NOTE: Here we provide additional notes to the description of Saaristo (2007) which is sufficient to distinguish the species. The diagnosis was based on material collected in Argentina (PBI_OON 42270 and 42252) and is valid to recognize this species in the Americas.

DIAGNOSIS: Males (fig. 11A–C) can be distinguished from other males of American species by the dorsal V-pattern on the abdomen, similar to that in O. obscura , and by the shape of the embolus, sinuous and with apical extensions (figs. 17D–F, 20N, O). Females (fig. 11D–F) have the same coloration pattern as males, genitalia with external pockets, and an anterior receptaculum wide at its base with V-shaped anterior apodemes at the tip (figs. 19G, 22D). Both sexes have lateral setae on the carapace margins, so far as we know, this character is absent in native American species.

DESCRIPTION: See Saaristo (2007).

ADDITIONAL OBSERVATIONS: Sperm duct slightly coiled (fig. 20N), female genitalia with plate-shaped posterior apodeme and a posterior receptaculum (fig. 22D).

DISTRIBUTION: Besides the type locality, Israel, recorded for United States, Brazil, and Argentina (maps 1 and 25). Present in other countries of Europe, collected at least in Portugal (A. Henrard, personal commun.).

NATURAL HISTORY: The species has been introduced into many countries and its natural origin is still unknown. In Argentina it has been collected in disturbed environments and in houses or other human buildings. In some cases the species was observed walking on walls or furniture or collected in leaf litter. The species is very similar to O. pavesii which is also widely distributed ( Spain to Slovakia, Bulgaria, Greece, Algeria, Canary Is., Egypt, and Yemen).
