Neolecanium perconvexum (Cockerell) is transferred to the new genus Octolecanium Kondo. The adult female
and first-instar nymph are redescribed and described respectively. A new species, O. guatemalensis Kondo is
also described based on the adult female. A key to separate the two species is given.

An annotated checklist of the soft scale insects (Hemiptera: Coccidae) is given for the Central American country of Guatemala. Host and locality data is presented for each species, along with notes on its taxonomic status. The list was developed from study of materials collected in Guatemala by the author and others during the years 1990-2007, and from a review of the lite-rature and records and slide material in the United States National Museum Coccoidea Collection. A study of these materials has increased the number of soft scale insects currently known from Guatemala to 29 species belonging to 23 genera. Guatemala currently ranks second in the number of soft scale insects known from Central American countries below Panama, which has 36 recorded species belonging to 18 genera.
... (5) bands of (often rather spinose) setae replacing the normal pairs of long prevulvar setae; (6) reduced legs with fine claw digitules; (7) antennae of reduced size and often with fewer segments; and (8) a short anal tube (Hodgson, 1994 (Gullan & Stewart, 1996;Kondo 2010aKondo , 2011Kondo & Williams 2004a, 2009Kondo et al., 2005).

... Steinweden (1929) chiefly defined the Toumeyella-group by the following features: (1) legs and antennae greatly reduced, but retaining their parts; (2) marginal and stigmatic setae small and inconspicuous or absent; (3) anal region with hypopygial setae; and (4) presence of quinquelocular pores in the perivulvar region. Currently, the Toumeyella-group is composed of Akermes, Bombacoccus Cyclolecanium, Megasaissetia, Neolecanium, Octolecanium, Pseudophilippia and Toumeyella (Kondo 2010a;Kondo & Williams 2002;Kondo et al., 2005).

A new species of soft scale insect from Colombia and Venezuela, Toumeyella coffeae Kondo sp. nov., is described and illustrated based on the adult female. A taxonomic key to the genera of scale insects of the Toumeyella-group and a list of 49 soft scale insect (Coccidae) species recorded from Coffea spp. worldwide are provided.
... Although no direct test of honeydew quality or output volume was undertaken here, some studies have shown a positive relationship between body size and these variables in hemipterans (Mittler 1958, Hertel and Kunkel 1977, Costa et al. 1999). Thus, the larger body size of Octolecanium ( Kondo et al. 2005) relative to C. viridis (Fredrick 1948) may result in differential attractiveness of honeydew to foraging workers. In addition, the absence of scale species in the canopy of 77% of surveyed Alchornea trees, the high density of C. viridis near nests in Yucca, and the increase in ant activity in coffee bushes after exclusion from an Inga canopy provides further support to our hypothesis. ...
The occurrence, intensity, and composition of mutualisms are dependent not only on the co-occurrence of mutualists, but also the broader biotic context in which they are embedded. Here, the influence of the specific nest tree identity of the ant Azteca instabilis (F. Smith) on the density of the green coffee scale (Coccus viridis Green) was studied in a coffee agroecosystem in southern Mexico. The hypothesis that an indirect competitive interaction for ant attendance occurs between a scale species (Octolecanium sp. Kondo) in the canopy of the shade tree Inga micheliana Harms and C. viridis, which inhabits coffee bushes (Coffea arabica) beneath the shade trees was tested. Coffee bushes beneath a different shade tree species (Alchornea latifolia Swartz) were used as an indication of C. viridis density in a noncompetitive environment. Results indicate that C. viridis occurs in significantly lower density adjacent to nests in Inga, supporting the hypothesis of indirect competition. Additional experimentation suggests that there is a mutualism between Azteca and Octolecanium and that this interaction may be mediated by a hierarchy in ant attendance of scale insects. Our results show the importance of considering the biotic context of ant-hemipteran mutualisms. In coffee agroecosystems, consideration of shade tree diversity and species composition may be directly applicable to the biological control of insect pests.
Three species of Mexican soft scales, Neolecanium leucaenae Cockerell, Toumeyella cerifera Ferris and T. sonorensis Cockerell and Parrott, are redescribed based on the adult females and are transferred to Neotoumeyella gen. nov. as N. leucaenae (Cockerell) comb. nov., N. cerifera (Ferris) comb. nov. and N. sonorensis (Cockerell and Parrott) comb. nov. Two new species, N. caliensis Kondo and Williams sp. nov. from Colombia and N. cephalanthi Kondo and Williams sp. nov. from the U.S.A, are described and illustrated based on the adult female. A key to the genera of New World Myzolecaniinae based on the adult female is provided. We designate lectotypes for N. leucaenae, T. cerifera and T. sonorensis.
