Remarks

Systematics: The adult males of Rh. cacticans are typical rhizoecine males, differing from those of other species seen here in having the following combination of character states: (i) tarsal digitules probably capitate, (ii) antennae long, with some segments bottle-shaped and most setae appearing to be in whorls, (iii) trochanter with 3 pairs of campaniform pores; (iv) trochanter with strong Y-shaped sclerotisations; (v) aedeagus broadening at apex, and (vi) shape and structure of the penial sheath, particularly the ventral internal extension. (Hodgson, 2012)
Structure: Colour photograph given by McKenzie (1967). SEM micrograph of wax secretion given by Foldi (1991). The adult males of Rh. cacticans are typical rhizoecine males, differing from those of other species seen here in having the following combination of character states: (i) tarsal digitules probably capitate, (ii) antennae long, with some segments bottle-shaped and most setae appearing to be in whorls, (iii) trochanter with 3 pairs of campaniform pores; (iv) trochanter with strong Y-shaped sclerotisations; (v) aedeagus broadening at apex, and (vi) shape and structure of the penial sheath, particularly the ventral internal extension.
Biology: Occurring on the roots of the host plants.
Economic Importance: This species may cause extensive damage in greenhouses at temperate regions (Dziedzicka, 1990; Zahradník, 1990). It species has been recorded as a pest in Colombia associated with coffee plants in their earliest development stage (until the second year) and at the first stage after cutting the trunk at its base for tree renovation. (Ramos-Portilla & Caballero in T. Kondo & G.W. Watson, 2022)
General Remarks: Description and illustration of adult female by Ferris (1953a), McKenzie (1967), Hambleton (1976), Zahradník (1990), Williams & Granara de Willink (1992), Kozár & Konczné Benedicty (2007) and by Danzig & Gavrilov (2009).
