Columbicola cicchinoi Tendeiro

( Figures 72, 73 )

Columbicola cicchinoi Tendeiro 1984: 87 . Type host: Streptopelia b. bitorquata (Temminck) .

Description

Similar to C. theresae , differing only in genitalic structure and various body measurements. Male head with APW, 0.127; HW, 0.28; HL, 0.55; HL/ HW, 1.96. Thorax with PW, 0.23; MW, 0.29. Genitalia as in Figure 72 ; mesosome rectangular with cap–like anterior expansion and 3 pores on each side, 1 anterior, 2 posterior; GW, 0.098. TL, 2.38. Female head with APW, 0.113 –0.137 (0.126); HW, 0.25–0.30 (0.277); HL, 0.52–0.57 (0.550); HL/ HW, 1.90–2.08 (2.02). Thorax with PW, 0.20–0.24 (0.217); MW, 0.25–0.30 (0.270). Ventral terminalia as in Figure 73 ; subgenital plate groove bell–shaped, narrow anteriorly, broad posteriorly; one individual with 3 short lateral subgenital plate setae (0.010), others without such. TL, 2.55–2.62 (2.58) .

Material

1 male, 3 females (including allotype female, 1 male, 2 female paratypes of C. cicchinoi ), ex S. bitorquata , Thailand, Java (2) .

Remarks

The shape and pattern of the male mesosome are unique. The bell-shaped subgenital plate groove of the female is shared with C. carrikeri Tendeiro , but the anterior portion is narrower in C. cicchinoi . We are suspicious of the C. cicchinoi record from Thailand, which is outside the range of the type host, S. bitorquata : western islands of Indonesia and the Philippines (del Hoyo et al. 1997). Although Tendeiro recorded a male as the holotype, one of the females available for examination was accidentally mislabeled as such, and, after checking with Tendeiro’s original description, this individual is now listed as part of the paratype series.
