15. veigasimoni species group

The single species of this group is from the host genus Phapitreron . It has the anterior marginal head carina rounded, complete ( Figures 122, 124 ); thickened region immediately posterior to dorsoanterior head plate; each side of metanotum with two long, two short setae ( Figure 2 ). Male antenna with enlarged scape, spur on third segment ( Figure 122 ); mesosome laterally spread, each side with two pores; parameres long, narrow ( Figure 123 ). Female subgenital plate groove broadly rounded, with slight posterior constriction; each side with 0–2 minute (0.005 –0.008) setae ( Figure 125 ).

Head as in Figure 124 ; APW, 0.137; HW, 0.28–0.29; HL, 0.50–0.51; HL/ HW, 1.76–1.79. Thorax with PW, 0.21–0.22; MW, 0.28–0.31. Ventral terminalia as in Figure 125 . TL, 2.18–2.20 (2.19) .

Material

Holotype male of C. veigasimoni , ex P. amethystinus , Philippines (1). 2 males, 2 females, ex P. leucotis , Philippines (1).

Remarks

The description of C. veigasimoni was based on a single male from P. amethystinus ; an additional male from P. leucotis was later described by Tendeiro (1969). The shape of the mesosome is unique among Columbicola having the two long, two short metanotal setal pattern. Until now, however, there has been no description of the female. The female is similar to the male, showing many of the same structural features of the head, such as the broad width and thickened band just posterior to the dorsoanterior plate. The female is also distinctly larger than the male. Its subgenital plate groove is wide, with a slightly angled anterior edge. Of the two female specimens, one had two pairs of lateral subgenital plate setae, while the other had none.
