Four new scale insect species (Hemiptera: Coccomorpha) associated with coffee roots in Colombia, South America, with identification keys for genera Newsteadia Green, 1902, Distichlicoccus Ferris, 1950, and Paraputo Laing, 1929

Coffee (Rubiaceae: Coffea spp.) is the host-plant of at least 214 scale insect species (Hemiptera: Coccomorpha). In this study, scale insects were collected from the roots of Coffea arabica Linnaeus, 1753 in five provinces of Colombia, South America, and the adult females were prepared as microscope slide mounts for identification. Four new scale species are described, based on the external morphology of the adult females: Newsteadia andreae n. sp. (Ortheziidae Amyot & Serville, 1843) differs from other Newsteadia Green, 1902 species by antennal length, presence of two spines on the trochanter, and absence of tubular ducts and groups of quadrilocular pores posterior to the vulva. Distichlicoccus takumasae n. sp. (Pseudococcidae Cockerell, 1905) is distinguished by having a few oral rim tubular ducts on both dorsum and venter and absence of circulus. Paraputo nasai n. sp. (Pseudococcidae) is characterized by having 16 pairs of cerarii, uniformity of length of its dorsal setae on all segments, and the sizes of oral collar tubular ducts. Pseudococcus luciae n. sp. (Pseudococcidae) is diagnosed by having few oral collar and oral rim tubular ducts, few multilocular disc pores, a small circulus and the eye not being associated with any sclerotized area or discoidal pores. The list of scale insect species on coffee roots in Colombia is updated to 65 species. Taxonomic keys to the New World species of Newsteadia, Distichlicoccus Ferris, 1950 and Paraputo Laing, 1902 are provided. To identify Pseudococcus luciae n. sp., modifications are provided for use with the existing taxonomic keys to New World and Neotropical mealybugs.

“…The Rhizoecidae are mealybugs that mostly live underground and feed on plant rootlets and are commonly known as “root mealybugs” or “ground mealybugs” (Williams 1998). The family includes 238 extant species belonging to 19 genera (García Morales et al 2016, Tanaka 2016) of which 69 species have been recorded from the Neotropical Region (Williams & Granara de Willink 1992, Kozár & Konczné Benedicty 2007, García Morales et al 2016, Ramos-Portilla & Caballero 2016). The associated host plants of the rhizoecid mealybug species are often not clearly understood, and when they are known from different host plants, it is unclear whether they have any preference for any plants.…”

Neotropical species of the scale insect genus Rhizoecus Künckel d’Herculais (Hemiptera: Coccomorpha: Rhizoecidae) found in soil sample material of the Hungarian Natural History Museum were studied. Two new Rhizoecus species, Rhizoecus kontschani Kaydan and Konczné Benedicty sp. n., and Rhizoecus granaradewillinkae Kaydan and Szita sp. n., are described and illustrated based on the adult females. Also, the adult females of Rhizoecus keysensis Hambleton and Rhizoecus pseudocacticans Hambleton are illustrated. An identification key and new additional locality records for the currently known Rhizoecus species are provided.

A study was conducted on the Neotropical scale insect genus Coccidella Hambleton (Hemiptera: Coccomorpha: Rhizoecidae) based on soil sample material deposited at the Hungarian Natural History Museum. Descriptions of the adult females of two new Coccidella species, i.e., Coccidella hexapora Kaydan & Konczné Benedicty, sp. n. and Coccidella kozari Kaydan & Szita, sp. n., are provided, plus a redescription and illustration of adult female of Coccidella kissbalazsi Konczné Benedicty & Kozár. An identification key and new additional locality records for the currently known Coccidella species are provided and the affinities of the new species are discussed.

Rhizoecus colombiensis Ramos & Caballero, a new species of hypogeal mealybug (Hemiptera: Coccomorpha: Rhizoecidae) and a key to the species of Rhizoecus from Colombia

Abstract: 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.
