摘要
Deladenus cocophilus n. sp. was isolated from infested coconut fruits in Winder, Balochistan, Pakistan. Descriptions are given of the entomophagous (insect-parasitic females) and mycetophagous (fungus-feeding) free-living females, males, and juveniles. The new species D. cocophilus resembles those species in which the excretory pore is situated anterior to the hemizonid, namely, D. apopkaetus Chitambar, 1991; D. leptosoma Gagarin, 2001; D. ipini Massey, 1974; D. laricis (Blinova and Korentchenko, 1986) Ebsarry, 1991; D. (siricidicola) canii Bedding, 1974; D. (s) imperialis Bedding, 1974; D. nevexii Bedding, 1974; D. (wilsoni) proximus Bedding, 1974; D. (s) rudyi Bedding, 1974; D. (s) siricidicola Bedding, 1968; D. (wilsoni) wilsoni Bedding, 1968 and D. minimus Chizhov and Sturhan, 1998. The new species differs from D. ipini in the absence of a post uterine sac vs. present; a = 17 to 30 vs. 35 to 40; stylet = 8 to 10 vs. 11 to 12 mu m and vulva-anus = 21 to 28 vs. 35 to 48 mu m. From D. apopkaetus it differs in tail length in female 22 to 28 vs. 31 to 43 mu m and in the male it is 24 to 32 vs. 30 to 46 mm. It differs from D. leptosoma in the c ratio in females, c = 21 to 37 vs. 16 to 22, presence of 6 lines in lateral field vs. 10 lines and slightly longer spicules 16 to 18 vs. 15 to 16 mu m. From D. laricis it differs in a shorter stylet length 8 to 10 vs. 11 to 12 mu m; in the c ratio in males 16 to 22 vs. 22 to 35 and hemizonid from anterior end 76 to 90 vs. 90 to 119 mu m. It also differs from the following species: D. (siricidicola) canii; D. (s) imperialis; D. nevexii; D. (wilsoni) proximus; D. (s) rudyi; D. (s) siricidicola; D. (wilsoni) wilsoni and D. minimus in having shorter tail length, lower values of a,b,c ratios and a slightly anteriorly located vulva in females.
