STATUS OF DICRANOCENTRUGA WRAY, 1953 WITH THE DESCRIPTION OF A NEW SPECIES (COLLEMBOLA : ENTOMOBRYIDAE)

Subsequently, the author had an opportunity to examine a series of collections of the species from Puerto Rico through the courtesy of Dr. Mari Mutt and it is noted that the species possesses the vestigial G and H ocelli and extra ocular structure as in other Paronella-like species of these regions. Thus Dicrallocentruga * is a valid genus and the name should be used for accommodating the Paronella-like species of the Ethiopian and Neotropical Regions.

Dicranocentruga is distinct from Campylothorax in all fundamental morphological characters although both of them possess extra ocular structure. In structural details, extra ocular structures of these two genera are different. The genus is distinct from Microparonella Carpenter (1916) in its relatively large size, presence of extra ocular structure and nature of ungues and its teeth. Moreover, the nature of scales clothing body, number of ocelli and structure of mucrones in the two genera are also different. It is distinct from Bromacanthus and Lepidonella in many striking characters like the structure of ungues and unguiculi, presence of extra ocular structure, arrangement of ocelli (in two longitudinal parallel rows vs. circular arrangement in Bromacanthus and Lepidonella). Moreover, the chaetotaxy of head in the species of Dicranocentruga is also distinct from those of Bromacanthus and Lepidonella (Mitra, 1993).

Kolkata.
Type-locality: Meru, Africa (3, 500 m. ). presence of extra ocular structure, arrangement of ocelli (in two longitudinal parallel rows vs. circular arrangement in Bromacanthus and Lepidone/la). Cephalic chaetotaxy in Dicranoceniruga is also distinct from the two above-mentioned genera.

Distribution : The species belonging to the genus Dicranocentruga have been recorded from different parts of Africa, Madagascar and South America. They are widely distributed and are endemic to the Ethiopian and Neotropical Regions.
S~ecies and sub-species included under Dicranocentruga Wray, 1953Borner (1903, Denis (1925Denis ( , 1933, Marlier (1945) and Delamare Deboutteville (1947Deboutteville ( , 1950aDeboutteville ( , b, 1952) described a number of species from the Ethiopian and Neotropical Regions under Paron ella which agree in all details with the diagnosis of Dicranocentruga given in this study. Aphysa eburnea, described by Delamare Deboutteville (1951 b) from Ivory Coast, has two rows of distinct dental spines and differs from other related species of in the possession of two ventral teeth of mucrones (I in other species) and longer antennae. Placement of this species in the genus Aphysa To Dr. Mari Mutt of Puerto Rico, I am specially grateful for sending me the material of the species, described by Wray, 1953, without which this work could not have been accomplished.
