Teuchophorus rifensis Nourti, Grichanov et Kettani,

2019

Teuchophorus rifensis Nourti, Grichanov, Kettani, 2019b: 106 . Type locality: Morocco: Rif , Chefchaouen, Oued Souk Lhad.

Teuchophorus bipilosus Vaillant, 1952: 8 , Fig. 17; Negrobov et al., 1984: 41, Fig. C (nec Becker, 1908, misidentification).

NOTES. Studying the papers of Vaillant [1952] and Negrobov et al. [1984], we have found a similarity of the hind tibia on photo of our T. rifensis and that on line drawings of T. bipilosus Becker, 1908 in those papers. Grootaert et al. [1995] studied the T. bipilosus types from the Canary Islands, found them corresponding with their material from France, and supposed that the Russian specimen [ Negrobov et al., 1984] belonged to an undescribed species. We have reexamined the T. rifensis holotype and found a place of the second broken seta on both left and right hind tibiae above the pictured long ventral seta. We conclude here that T. rifensis is also distributed in Algeria and Russian Krasnodar Territory in addition to Morocco. T. bipilosus was also reported from Madeira and Iberian mainland, but association of these records is unclear at present. The two species can be distinguished as follows:

1. Hind tibia with one fine and long ventral bristle, 3–3.5 times as long as diameter of tibia, and one very long ventral bristle, 4–5 times as long as diameter of tibia; adjacent hairs distally about as long as diameter of hind tibia; body length

2 mm ( Algeria, Morocco, Krasnodar Territory of Russia)

............... T. rifensis Nourti, Grichanov et Kettani, 2019 — Hind tibia with 2 equally long ventral bristles, 4–5 times as long as diameter of tibia; adjacent hairs distally about two times as long as diameter of hind tibia; body length 1.8 mm

( France, Portugal, Spain) ...... T. bipilosus Vaillant, 1952
