TYPE SPECIMENS. — Algeria • ♂, ♀; syntypes; North Algeria ; LSUK.

DISTRIBUTION. — According to Dirsh (1950 [1951]), Truxalis nasuta is distributed across the Canary Islands , Southern Europe (Spain, Italy, Greece, and Chypre), North Africa (Morocco, Algeria,Tunisia, Libya, and Egypt) and Palestine. It has recently been found in Saudi Arabia (El-Hawagry et al. 2013).

DATA FROM LITERATURE FOR CENTRAL AND SOUTHWESTERN TUNISIA. — Widespread throughout Tunisia from Cape Bon to the oases of Chott el Djerid ( Bonnet & Finot 1885; Finot 1895); Gabes ( Vosseler 1902a; Massa & Rizzo 1998); Gafsa ( Vosseler 1902a); Kebili ( Finot 1895).

NEW DATA FOR CENTRAL AND SOUTHWESTERN TUNISIA. — Kasserine, Sbeitla; Gafsa, Douwara, El Guetar, Sened; Kebili, Essagui.

HABITAT. — Frequently found in old farms, this species occupies grassland, tufty gramineous areas, and cultivated fields. It is only uncommonly spotted in dry grasses. According to many studies, T. nasuta is almost always correlated with Graminae crops and steppe environments ( Usmani 2008; Moussi et al. 2011).

DNA SEQUENCES. — We generated a new sequence for the mitochondrial marker COI (664 bp) ( Table 4 ).
