ABSTRACT
The Neotropical scale insect genus Ripersiella Tinsley (Hemiptera: Coccomorpha: Rhizoecidae) was investigated, based on soil samples deposited at the Hungarian Natural History Museum. Description and illustration of a new species, Ripersiella incarum Kaydan Szita sp. n., and an identification key and new additional locality records for the currently known Ripersiella species in the Neotropical region, are provided and discussed.

Herein we describe a new species, Tillancoccus koreguajae Caballero & Ramos, sp. n. (Hemiptera: Coccidae) from Colombia collected on sugarcane. Pinnaspis strachani (Cooley) is also recorded on sugarcane for the first time worldwide. An updated list of seven species of Coccomorpha on sugarcane in Colombia is provided, including information on its distribution, biology, and mutualistic ants for each species. Seven species of scale insects (Hemiptera: Coccomorpha) have been recorded previously on sugarcane, Saccharum officinarum L. (Poaceae) in Colombia: Pseudococcidae: Dysmicoccus boninsis (Kuwana), D. brevipes (Cockerell), Pseudococcus calceolariae (Maskell), Saccharicoccus sacchari (Cockerell); Coccidae: Pulvinaria elongata Newstead; Diaspididae: Duplachionaspis divergens (Green) and Serenaspis minima (Maskell). However, the record of S. minima in Colombia is considered doubtful as there are no voucher specimens from Colombia and because the distribution of this species is currently limited to the Australasian region. Pseudococcus calceolariae is present in Colombia but its record on sugarcane is also doubtful. A taxonomic key for the identification of scale insects on sugarcane in Colombia is provided.

A new species belonging to Rhizoecus Künckel d'Herculais (Hemiptera: Coccomorpha: Rhizoecidae) is described, with hosts and distribution data in the New World. A dichotomous and illustrated key for the twelve species of Rhizoecus recorded from Colombia is presented.
