Suhardjono, Yayuk R. & Deharveng, Louis, 2001, Telobella kemiri, a new species of Lobellini (Collembola: Neanuridae) from Lombok island (Indonesia), Zootaxa 15, pp. 1-8 : 5-8

Description of Telobella kemiri new species

Type­material. ­ Holotype female, Indonesia: Lombok , Sesaot, hutan Kemiri , alt. 300 m, litter, by hand, 18/11/1986, Y. R. Suhardjono leg. (sample N­04) ­ Paratypes: 26 specimens, ibid . Material deposited in the Museum Zoologicum Bogoriense collection (holotype, 19 paratypes) and in the Museum National d’Histoire Naturelle de Paris (6 paratypes).

Etymology. ­ The new species was collected from leaf litter beneath Aleurites moluccana , the candle nut tree, locally called “ kemiri ”.

Description

Body length: 1100 to 1800 µm. Body flattened, wide, with the sixth abdominal tergite weakly lobed ( Fig. 7 ). Colour: white in alcohol. Eyes black, small, 3+3, subequal. Dorsointernal tubercles and those of the head weakly or not developed. Presence of an additional integument swelling devoid of chaetae between and behind De and DL of abd.IV ( Fig. 6 ). Abd.VI not hidden by abd.V. Three kinds of ordinary dorsal chaetae: (i) and (ii), mesochaetae and microchaetae, thin and acuminate, on all parts of the body; (iii), macrochaetae, thin, straight, slightly rugose, very slightly sheathed, and blunt ( Fig. 5 ), except the lateral ones which are acute apically. No plurichaetosis. S­chaetae thin, shorter than the closest macrochaetae; supernumerary S­chaeta only on lateral tubercle of abd.IV ( Fig. 7 and Table I ).

Head. S­chaetae of ant.IV medium­sized, moderately thick, bent, subequal; apical vesicle trilobed. Buccal cone rather short; labrum triangular­truncated at the apex, with 2 distal chaetae ( Fig. 1 & 3 ); labium with 10 chaetae ( Fig. 4 ). Maxilla styliform; mandible thin, tridentate with the apical tooth subdivided in three toothlets ( Fig. 2 ). Chaetotaxy of head as in Fig. 7 and Table I.

Post­cephalic chaetotaxy as in Fig. 7 and Table I. Chaeta M present on tibiotarsus. Claw with a strong internal tooth.

Discussion. ­ The new species T. kemiri is the first Neanurinae cited from Lombok and the second Telobella of Indonesia. By the inclusion of the S­chaeta in the tubercle ( De +DL) on abd.V, it is close to T. wayang .
