Nematode Parasites of Vertebrates of East Pakistan: Vii. Capillaria Copyschi Sp. Nov.

Abstract

Capillaria copyschi sp. nov. is described from Copyschus c. saularis.Capillaria copyschi sp. nov. T h e material available consisted of two male worms, the heads of which were missing, and a number of complete females.Host: Copyschus c. saularis. Location: Small intestine. Desmip,hionBody very slender (Fig. 51, covered by a series of cuticular bosses. Oesophageal portion (Fig. 1) shorter and slightly thinner than posterior portion. Vulva near to mid-body just behind junction of oesophagus and intestine, provided with a protrusibtt: funnel-shaped cuticular appendage (Fig. 7), and with the cuticle of the body inflated anterior and posrerior to the vulva. Posterior end of female cylindrical and rounded. Anus (Fig. 6) subterminal. Egg barrelshaped (Fig. 8) and thiclr; plugs very h r~a d ;innermost egg shcIl bent t o form collar; outer shell with reticulation.Caudal end of male provided with rounded bursalike membrane, supported 1Manuwript remived May 20, 19m.

The genus Capillaria Zeder, 1800 (Nematoda) in British passerine birds

“…The use of the term 'lateral alae' for that part of the bursa which extends anteriorly to the caudal end of the body is confusing, and the ' papillae' supporting the bursa are not split into two rami-the ventral 'rami' are in fact the bilobed end of the body. Gupta (1960) established the species C. copyschi for specimens recovered from Copyschus copyschus saularis (Indian dial bird), a member of the Turdidae. The material on which this species was based consisted of two fragments of male worms and a number of females.…”

Nematode parasites of Oceanica

“…2/) REMARKS. Capillaria pitti resembles in many respects G. ovopunctata, a species recorded widely from Turdinid hosts in Europe, but found also in the U.S.A. (Read, 1949), Canada (Mawson, 1956) and East Pakistan (Gupta, 1960). The major points of difference in the female worms are the consistent absence of a vulval appendage in C. pitti (an appendage is always present in G. ovopunctata), a shorter vagina and smaller eggs; in the males, the bursa of G. pitti is smaller and altogether more delicate, the lateral projections at the caudal end are bilobed and the spicule lacks the expanded distal tip characteristic of G. ovopunctata.…”

It is interesting that C. ovopunctata has been recorded from Copyschus saularis in East Pakistan (Gupta, 1960;Wakelin, 1966).…”
