Columbicola sphenurus Tendeiro View in CoL

( Figure 171 View Figures 165–189 ) Columbicola sphenurus Tendeiro 1984: 92 . 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 View Figures 165–189 ; 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 View Figures 165–189 ) 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 View Figures 165–189 ; 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 View Figures 165–189 ; subgenital plate groove rounded anteriorly, distinct expansions posteriorly. TL, 2.38–2.55 GoogleMaps .

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.
