2. guimaraesi View in CoL species group

This group consists of three species from the host genera Chalcophaps , Cryptophaps , and Columba . Like the columbae group, they have the anterior marginal head carina rounded, complete ( Figure 26 View Figures 19–39 ); body elongate ( Figure 1 View Figures 1–18 ); and each side of metanotum with two long, two short setae ( Figure 2 View Figures 1–18 ). Male antenna with enlarged scape, spur on third segment; mesosome ovoid, laterally thickened, with numerous pores, and parameres with medial expansions ( Figure 27 View Figures 19–39 ). Female subgenital plate groove elongate, shape variable ( Figures 29, 32, 34 View Figures 19–39 ); each side with 3–8 short to long setae.

Material

16 males, 16 females (including 1 male, 1 female paratypes of Columbicola guimaraesi ), ex Chalcophaps indica , Taiwan, Philippines, Nepal, Malaysia, India, New Hebrides (12) . 1 male, 1 female, ex C. stephani Pucheran , New Guinea (1).

Remarks

This species was originally described by Tendeiro (1965) as a complex of 2 subspecies, C. g. guimaraesi and C. g. grandiusculus . Tendeiro (1967) later added a third subspecies, C. g. vitiensis . After examining numerous individuals of each of the three subspecies, the differences between them were found to be quite noticeable, especially in the variation of the female ventral terminalia. For this reason, each of the three subspecies of C. guimaraesi is recognized as a full species. Although there is some size overlap, C. guimaraesi is the smallest of the guimaraesi group lice. Male identification is based on overall body dimensions and subtle differences in structure of the genitalia. The female is more easily identified by subgenital plate differences in the shape of the groove and the length and number of setae. The mesosome of C. guimaraesi has a reduced thickening on its lateral edges compared to C. vitiensis and C. grandiusculus . Individuals from the type host Chalcophaps indica , and those from C. stephani , were found to be indistinguishable, thus representing a new host record for C. guimaraesi .
