Type host: Treron s. sphenurus (Vigors) . Description Similar to C. elbeli , differing in structure of male genitalia. Male with HW, 0.28–0.30 (0.290); HL, 0.55–0.59 (0.570); HL/HW, 1.96. Thorax with PW, 0.20–0.21 (0.207); MW, 0.28–0.32 (0.303). Genitalia as in Figure 171 ; parameres elongate, thickened anteriorly, with small lateral indentations; mesosome thick, ‘‘V’’-shaped, indented anteriorly; GW, 0.113. TL, 2.24–2.32 (2.29). Female with HW, 0.29–0.31 (0.303); HL, 0.58–0.60 (0.591); HL/HW, 1.87–2.00 (1.96). Thorax with PW, 0.20–0.21 (0.207); MW, 0.29–0.31 (0.309). Subgenital plate groove ovoid, edges rough. TL, 2.36–2.59 (2.48). Material 1 male paratype of C. sphenurus , ex T. sphenurus , Thailand (1). Remarks Several of the specimens used to describe C. sphenurus were originally part of the type series for Columbicola elbeli . C. sphenurus was later recognized as a separate species because of differences in the male genitalia of lice from T. pompadora , the type host for C. elbeli , versus lice from T. sphenurus , the type host of C. sphenurus . Tendeiro (1984) also recorded C. sphenurus from T. formosae Swinhoe. Measurements for the description above, except genitalic width, were taken from three males and seven females in Tendeiro (1984) . Columbicola wardi Tendeiro ( Figures 172, 173 ) Columbicola wardi Tendeiro 1965: 310 . Type host: Treron a. apicauda Blyth. Description Male head with APW , 0.142 –0.157 (0.149); HW , 0.31–0.32 (0.313); HL, 0.58–0.60 (0.593); HL/ HW , 1.87–1.94 (1.89); medioposterior setae short, not reaching halfway to posterior head margin. Thorax with PW , 0.25; MW , 0.33–0.35 (0.333). Genitalia as in Figure 172 ; mesosome weakly indented anteriorly, laterally sclerotized; GW, 0.113 –0.122 (0.119). TL, 2.21–2.30 (2.26). Female with APW , 0.152 –0.157 ; HW , 0.33; HL, 0.61–0.63; HL/ HW , 1.85–1.91. Thorax with PW , 0.25; MW , 0.34–0.37. Ventral terminalia as in Figure 173 ; subgenital plate groove rounded anteriorly, distinct expansions posteriorly. TL, 2.38–2.55 . Materials 3 males , 2 females (including 2 male , 2 female paratypes of C. wardi ), ex T . a. apicauda , Thailand (2). Remarks While superficially resembling C. elbeli , the male mesosomal and female subgenital plate structures distinguish C. wardi . It is interesting to note that, upon re-examining the type series of C. e. elbeli , Tendeiro (1984) discovered that the male specimen from Treron oxyurus (Temminck) was actually identical to C. wardi , which he had described nearly 20 years earlier.
