A new species of springtail (Symphypleona, Collophoridae), Collophora brasilis sp. nov., is described, the first species known from Brazil. The species is distributed from the coastal region to the semi-arid region in northeastern Brazil. It is characterized by the reduction in the trochanteral setae and teeth on the empodial complex. Diagnostic features are illustrated and compared to other members of the genus.

The genus Collophora (Symphypleona: Collophoridae) was first described by Richards in 1956 (unpublished) but published only in 1964 by Delamare Deboutteville & Massoud (1964a), the type species of the genus C. quadrioculata (Denis 1933) from Costa Rica, was originally placed in the genus Arrhopalites. Six species are known, C. africana Delamare Deboutteville & Massoud 1964b and C. sudanica Hüther 1967 from Africa, C. mysticiosa Yosii 1966 and C. subquadrioculata (Denis 1948) from India and Vietnam and C. remanei Delamare Deboutteville & Massoud, 1964a from Peru. The distribution of the species strongly suggests a Gondwanan origin for the genus, reinforced by the new species described here from Brazil. The only species known from Nearctic Region is C. quadrioculata, which must have invaded Central and North America after the formation of the Isthmus of Panama.

The genus Collophora presents 4 eyes each side of head, tenent hairs absent, proximal setal field of metatrochanter absent, fifth abdominal segment fused to the great abdomen, trichobothria D capitate on a conspicuous papilla (Richards 1968; Betsch 1980) with setae Pl and P2 modified into 2 capitate sensilla (Bretfeld 1994), figured for the first time in C. africana by Delamare Deboutteville & Massoud (1964b).

Collophora brasilis sp. nov. from Northeastern Brazil, ranges from the rainy Atlantic Forest close to littoral, to the semi-arid Caatinga Forest more than 200 km away from the coast. This is the first species of Collophora recorded from Brazil, the second from South America.


Head and dens chaetotaxy labeling follow Christiansen (1966) and Christiansen & Bellinger (1998), anal valve and apical organ of Ant. III follow Lawrence (1979) and Nayrolles (1991) respectively, trichobothria and surrounding setae as Richards (1968) and Bretfeld (1994). The abbreviations used along the description are the following: Ant, antennal segment; Abd, abdominal segment; CD, cephalic diagonal

  • Etymology

    The species was named brasilis as the first Collophora species described from Brazil. Terra Brasilis is among the ancient Latin names given to Brazil.

  • Distribution and Habitat

    Good's Biogeographic Zone 27 (Good 1974). The species is distributed in Northeastern Brazil, in Atlantic Forest remnants, semi-deciduous Forest and extending westward to Caatinga semiarid forest. The specimens studied were collected in Paraiba State at coordinates S 6°42′40.3′ W -35°10′40.3″, S 6°48′ 12.7″W -35°06′ 27″ and S 7° 28′ 58″ W -36° 39′ 54″, and in Bahia State at coordinates S 9° 24′ 23.4″ W -40° 30′ 9.2″ and S 9° 24′ 49.4″ W-40° 28′ 42.3″.

    The species inhabits on leaf litter in forest grounds from wet littoral zone to semi-arid (rainy winter, less than 500 mm/year), dwelling riparian environments associated to plant debris and moisture. Climate according to Köppen's system is As (Koppen 1936; Shear 1966).

  • Remarks

    Collophora brasilis sp. nov. can be recognized from all known species of the genus by the reduced number (1/1/1) of seta on trochanter (3/2/2 in C. africana, C. remanei and C. sudanica), having small abdomen seta C swollen instead of winged, small abdomen Al and B3 smooth, and lacking the corner tooth in all unguiculi. In addition, the number of clypeolabral setae (6:2:5:4) separates the new species from C. mysticiosa (6:2:3:4) and C. sudanica (6:5:5:4). The new species presents a sensillum at the dorsal surface of great abdomen each side of the body, aligned with trichobothria A, the same sensillum is present in C. sudanica.

    The 2 special sensilla posterior to trichobothria D (Bretfeld 1994) present in C. brasilis sp. nov., is similar to those seen in C. africana (Delamare Deboutteville & Massoud 1964b), described as short trichobothria with the same structure, but completely transparent, placed near the base of each trichobothria D.

    Hüther (1967) presents an identification key to all the 6 previously known species. The revised chaetotaxy (Bretfeld 1994) re-defined the genus, although detailed chaetotaxy of great abdomen and anal valve remains undescribed for most named species of Collophora. Most species need to be re-described, as original descriptions are too incomplete to allow clear diagnosis for the genus and to recognize the real limits of species. Therefore updates to the identification key are useless until the genus is revised.
