Type host: Goura c. cristata (Pallas). Description Body robust. Male head as in Figure 152 ; anterior head region distinctly indented; medioposterior setae short, not reaching posterior head margin; APW , 0.186 –0.198 ; HW , 0.51–0.52; HL, 0.61; HL/ HW , 1.17–1.20; SL, 0.093. Thorax with PW , 0.27–0.30; MW , 0.36–0.38. Genitalia as in Figure 153 ; mesosome ovoid, transverse sclerites crossing mesosomal midline, with 4 medial, 2 lateral pores; GW, 0.127. TL, 1.96–2.03. Female head as in Figure 154 ; APW , 0.201 –0.206 ; HW , 0.51–0.52; HL, 0.64; HL/ HW , 1.18–1.23. Thorax with PW , 0.31–0.32; MW , 0.39–0.41. Ventral terminalia as in Figure 155 ; subgenital plate groove broadly triangular, smoothly rounded anteriorly, with uneven lateral edges. TL, 2.33–2.35 . Material Holotype male, allotype female, 1 male , 1 female paratypes of C. gourae , ex G. c. cristata , Irian Jaya (1). Remarks This species is similar to C. paradoxus Tendeiro , differing by its shortened preantennal head region and structure of the male genitalia. The low HL/HW ratio further separates C. gourae from other members of the longiceps group.
