The Collembola are small, entognathous,
wingless hexapods which poses a spring like jumping organ under the fourth
abdominal segment known as furcula due to which they are called
springtails. The presence of antennae
and absence of cerci distinguishes it from other entognathous
hexapods—Protura (with antennae and cerci absent) and
the Diplura (with antennae and cerci or pincers
present).
There are 9,037 described species of Collembola
present worldwide (Bellinger et al. 2019).
In India the collembolan fauna constitutes about 342 species of 113
genera belonging to 20 families in which the family Paronellidae
consists of 69 species of 15 genera (Mandal 2018). The member of the subfamily Paronellinae Borner distinguished
from other entomobryids by straight unringed dentes lacking spines but with terminal bladder like
projection with a short and blunt mucro which is
quite different from other entomobryids (Mandal & Suman 2016). In the subfamily Paronellinae
the genus Dicranocentroides consists of five
species in India (Hazra & Mandal 2015) and 21
species in the world (Bellinger et al. 2019).
The earlier distribution of the species Dicranocentroides indica
Handschin in India was from Assam, Meghalaya,
Manipur, Mizoram, Nagaland, Arunachal Pradesh, Sikkim, Uttar Pradesh, Andhra
Pradesh, Chattishgarh (Mandal 2018). Here, the first report details and
description of Dicranocentroides indica was made from Sundargarh,
Odisha (Figure 1).

Diagonistic Characters: Colouration: Whole
body golden brown in colour with faint purple blue pigment. The antennal segment I, II and III with a
distinct distal bluish ring and IV mostly with bluish pigment. Legs with dark brown pigment; furca with diffused blue pigment. Clothing: Body covered with scales, cervix
and anterior margin of II thoracic segment is covered with a collar of
acuminate setae; macrachaetae obliquely truncated on
II, III thoracic segment and I, II and III abdominal segments. At the posteriomedial
part the segment IV, V and VI contains acuminate setae. Head: Two dark ocellar
field, each having eight ocelli in two longitudinal parallel rows. Antennal segment I and II were stouter;
segment IV superficially annulated, apical sense knobs not distinct. Thorax: Relative length index of segments
II:III :: 12:9, legs similar; unguis with paired basal and medial unpaired
teeth, unguiculus lanceolate in shape; tenant hair
long narrow and clavate. Abdomen: long
ventral tube with protrusible vesicle retracted. Manubrium: Mucrodens
22:35, short mucro quadrangular with six striated
teeth (Figure 2).
Remarks: Handschin
(1929) first described this species in Aphysa
genus from Europe. In course of
revision of Indian collembola fauna, Mitra (1975)
transferred the generic status to Dicranocentroides
on the basis of the character of the genus present in the insect.
