Xerophytacolus tubuverpus sp.n.
( Figs 12–14 View FIGURES 8 – 14 , 98–122 View FIGURES 98 – 112 View FIGURES 113 – 122 )
Diagnosis. Aedeagal shaft tubular, uniformly curved dorsolaterally ( Figs 109, 110 View FIGURES 98 – 112 ). Pygofer lobe with apex of median process curved ventrad ( Figs 107, 108 View FIGURES 98 – 112 ). Plate apex truncate; laterally weakly striate; basally lateral and medial margins convergent, subparallel ( Fig. 106 View FIGURES 98 – 112 ). Sternite 7 of female with wide, shallow rounded notch, about as wide as sternite ( Fig. 113 View FIGURES 113 – 122 ).
Etymology. Latin, tubus pipe, verpus penis, for the tubular shape of the paired aedeagal shafts.
Male. Measurements. (n=10) Length: apex of vertex to apex of tegmina 2.40–2.53 mm; apex of vertex to apex of abdomen 2.00– 2.12 mm; vertex 0.52–0.60 mm; next to eye 0.33–0.35 mm; pronotum 0.38–0.41 mm; scutellum 0.40–0.48 mm. Width: head 0.85–0.90 mm; pronotum 0.82–0.89 mm; scutellum 0.55–0.62 mm. Ocellus: diameter 2.64–3.13 µm; ocellocular distance 1.24–1.73 µm.
Male. Genitalia. Pygofer lobe with median process, attached subbasally on inner margin, apex curved ventrad ( Figs 107, 108 View FIGURES 98 – 112 ) with narrow, variable process directed dorsoanteriad ( Fig. 108 View FIGURES 98 – 112 ). Anal tube incised half way into pygofer ( Fig. 105 View FIGURES 98 – 112 ). Aedeagal shafts tubular, parallel at base, curved dorsad and divergent apicad ( Figs 109, 110 View FIGURES 98 – 112 ), gonopore apical, oblique. Connective weakly sclerotized ( Fig. 111 View FIGURES 98 – 112 ). Style apophysis apex blunt, small subapical ventral spine ( Fig. 112 View FIGURES 98 – 112 ). Plate apex truncate, right-angled, weakly sclerotized ( Fig. 106 View FIGURES 98 – 112 ), 12–17 macrosetae. Anterior and posterior abdominal apodemes in posterior view as in Figs 103 and 104 View FIGURES 98 – 112 , in dorsal view similar to the apodemes of Xc. claviverpus ( Figs 79, 80 View FIGURES 77 – 87 ).
Female. Measurements. (n=6) Length: apex of vertex to apex of tegmina 2.56–2.83 mm; apex of vertex to apex of abdomen 2.31–2.68 mm; vertex 0.60–0.71 mm; next to eye 0.34–0.37 mm; pronotum 0.41–0.44 mm; scutellum 0.42–0.50 mm. Width: head 0.91–0.96 mm; pronotum 0.87–0.93 mm; scutellum 0.54–0.65 mm. Ocellus: diameter 2.87–4.13 µm; ocellocular distance 1.23–1.80 µm.
Female. Genitalia. Sternite 7 with wide, rounded notch ( Fig. 113 View FIGURES 113 – 122 ). Valvula 3 with about 7 setae in apical half ( Fig. 114 View FIGURES 113 – 122 ), additional fine setae basally. Valvula 2 ( Fig. 122 View FIGURES 113 – 122 ) serrate dorsally on apical third, serration very fine, on rounded protrusions ( Figs 120, 121 View FIGURES 113 – 122 , serration at apex, Fig. 119 View FIGURES 113 – 122 , serration medially). Valvula 1 lanceolate ( Fig. 116 View FIGURES 113 – 122 ), imbricate microsculpture ( Figs 115, 117 View FIGURES 113 – 122 , at apex, Fig. 118 View FIGURES 113 – 122 , more rectangular medially).
