( Figures 91–93 View Figures 78–94 )

Type host

Macropygia nigrirostris Salvadori.

Description

Similar to C. exilicornis , differing as follows. Male head as in Figure 91 View Figures 78–94 , with medially enlarged anterior carina and thickened sagittal band; HW, 0.31; HL, 0.58–0.59 (0.587); HL/HW, 1.87–1.90 (1.89); SL, 0.132 –0.137 (0.135). Thorax with PW, 0.24; MW, 0.30– 0.32 (0.31). Genitalia as in Figure 92 View Figures 78–94 , with tongue–like extension protruding posteriorly between parameres, and with 2 pores; GW, 0.083 –0.088 (0.086). TL, 2.35–2.48 (2.39). Female as in Figure 93 View Figures 78–94 ; HW, 0.32–0.34; HL, 0.63–0.64; HL/HW, 1.88–1.97. Thorax with PW, 0.25–0.27; MW, 0.35. TL 2.87–2.92.

Type material

Holotype male at NMNH, ex M. nigrirostris , Papua New Guinea: Morobe, Kalalo, 19-Aug- 1966, Wilkes , BBM–NG 52911 . Paratypes ex M. nigrirostris , Papua New Guinea, at NMNH, OSU: 1 male, 1 female, same data as holotype ; 1 male, 1 female, West Sepik, Feramin , 15-Jun-1971, A. B. Mirza, BBM–NG 100321 .

Remarks

Although quite similar to C. exilicornis , the distinct tongue-like extension of the mesosome is unique among lice in the angustus group. Its occurrence on two separate hosts collected years apart convinces us of the validity of this species. The females are currently indistinguishable.

Etymology

This species is named for Don C. Arnold, Survey Entomologist, Oklahoma State University, in appreciation for his assistance with the loan of large numbers of lice for this study.
