Diagnosis. Aedeagus with apex of shaft about as wide as midsection; dorsal apodeme elongate, half to three quarters as long as shaft, subparallel to shaft, narrowly attached to atrium, preatrium reduced; teeth of shaft medially at posterior margin with single tooth and paired teeth at lateral margins; apex of shaft at anterolateral margin with numerous small teeth.

Etymology. Retrospectively, not in Linnavuori (1961). Named for the small size of this leafhopper in Latin, parvus, little, minor, masculine or feminine; parvitas, - atis, feminine, littleness, insignificance; parum, too little. Gender masculine.

Terminalia.

Male

Segment 10. Lateral margin convergent, slightly convex, in dorsal view length/width=0.90–0.99 (n=18), ( Fig. 7A, B View FIGURE 7 ).

Pygofer lobe. 3–6 macrosetae, rarely seven or eight, 38–90 µm in length ( Fig. 7B, F View FIGURE 7 ); membranous apical and medial lobe as in Fig. 7F View FIGURE 7 .

Subgenital plate. Greatest length/greatest width=0.85–1.16. Apex of apophysis of style inserted less than halfway into subgenital plate ( Fig. 7C View FIGURE 7 ).

Style. Greatest length/greatest width=3.43–4.11, length apophysis/greatest length=0.17–0.25; angle 49–71° ( Fig. 7G View FIGURE 7 ); apophysis curvate, margins subparallel.

Connective. Greatest width across arms/width of apex of stem=1.77–2.16, length arms/length stem=1.28–3.73; angle of arms 78–95°; greatest length/greatest width=0.45–0.57 ( Fig. 7H View FIGURE 7 ).

Aedeagus. Shaft straight, tubular, medially with paired, lateral teeth and single posterior tooth, variable in position, size and orientation, shaft at apical anterior margin with numerous small teeth; gonopore marginal, wide at apex, tapered along posterior subapical margin, narrow subapically; dorsal apodeme elongate, half to three quarters as long as shaft ( Fig. 7D, E View FIGURE 7 ).

Female.

Sternite 7. Isosceles trapezoid (distal width/basal width=0.65–0.67, greatest length/greatest width=0.46–0.51), lateral margins straight or curvate; posterior margin rounded medially with small, narrow bilobed or uniform projection or without projection, sclerotized medially ( Figs 1G View FIGURE 1 , 8A View FIGURE 8 ).

Valvula 1. Parallel-sided, apex acuminate ( Fig. 8I View FIGURE 8 ), sculpture pattern commonly reticulate apically and medially ( Fig. 8K, 8L View FIGURE 8 , respectively), striate towards base (similar to other species of Colistra , e.g., Fig. 10M View FIGURE 10 , 12N View FIGURE 12 ).

Valvula 2. Serration less than half the length of valvula 2 ( Fig. 8H View FIGURE 8 ), teeth curvate, trough with fine teeth, serration at apex, similar throughout ( Fig. 8J View FIGURE 8 ).

Valvula 3. 12–18 marginal to submarginal macrosetae at apex, 21–32 µm long ( Fig. 8M View FIGURE 8 ). Whole valvula as in other species of Colistra , e.g., Fig. 10E View FIGURE 10 .

Valvifer 1. Rhomboid with dorsal and ventral margin broadly rounded, anterior margin narrowly rounded, posterior margin acute ( Fig. 8C, D, E View FIGURE 8 ), in dorsal view fused medially ( Fig. 8B View FIGURE 8 ).

Valvifer 2. Apices narrowly rounded, length/width=1.23–1.66 ( Fig. 8G View FIGURE 8 ), sculpture sparse, microtrichia and scale-like structures, marginal and submarginal, few circular submarginal pore-like structures (no setae found on eight valvifers in six dissected ovipositors) ( Fig. 8F View FIGURE 8 ).

Remarks. Males and females share similar proportions, with the latter appearing smaller, and with a shorter crown and more obtuse crown angle. The male aedeagus of C. parvulus has the separate and elongate dorsal apodeme and short preatrium, except in the Clanwilliam specimen with a slightly longer preatrium. Variation is recognized in the relative position of posterior and lateral paired teeth, from almost opposite to lateral pair or more basal, and the dorsal apodeme three quarters to half as long as shaft, parallel or subparallel to the shaft. The sternite 7 of examined females appears consistently rounded, with little or no damage, and length/width slightly larger (0.46–0.51) than in C. bucapitatus sp. n. (0.42–0.46) and C. acapitatus sp. n. (0.41–0.45). The sternite 7 in C. semialius sp. n. (0.48–0.55) is similar to that of C. parvulus (0.46–0.51).
