Remarks

• Systematics: C. urichi appears morphologically closest to C. cylindrium and C. melissophilum, but can be easily recognized by an extra pair of orbicular pores. The first-instar nymphs of C. urichi appear morphologically similar to those of C. inquilinum, but can be easily separated from the latter by the presence of a claw denticle (absent in C. inquilinum). (Kondo, 2010b) 2 syntypes of Neolecanium urichi, reportedly deposited at the USNM (Cockerell, 1894) as slides, are missing. Therefore, a lectotype was designated in Kondo, 2010b from a collection of specimens slide-mounted from the type dry material labelled: "Lecanium urichi (Cockerell)", deposited at the USNM. Cockerell’s original description of L. urichi agrees well with the morphology of the specimens obtained from the dry material. Lecanium urichi was found to be a member of the genus Cryptostigma, and is morphologically identical to Akermes quinquepori Newstead, which was recognized by Kondo, 2010b as a junior synonym. Like most of the species in the genus, C. urichi is usually tended by ants within cavities and crevices in the bark and stems of its host (Morrison, 1922). Green (1933) collected C. urichi (as C. bunzlii) from large roots of Erythrina sp. in Surinam, although the roots referred to by Green were probably the large exposed roots and not those underground. (Kondo, 2010b)
• Structure: Red-brown, very shiny, nearly circular, moderately convex, segments marked on upper surface by black or blackish transverse lines interrupted at intervals (Cockerell, 1894). Young adult females orangy in life (J.H. Martin notes on slides collected in Belize, 6/20/2002). (Kondo, 2010b) The adult female C. urichi can be diagnosed by the following features: (i) oval body shape, (ii) dorsal setae absent, (iii) dorsum with 5 orbicular pores, (iv) cribriform platelets present, (v) dorsal surface of anal plates with about 10-17 setae, (vi) with 3 stigmatic setae per cleft, although often broken off, (vii) apodemes conspicuous on dorsal derm marginally and submarginally, and (viii) presence of a marginal band of multilocular disc-pores around abdomen. (Kondo, 2010b) The first-instar nymph of C. urichi can be diagnosed by the following combination of features: (i) dorsal setae present in 2 longitudinal rows of 5 pairs, (ii) each anterior and posterior stigmatic cleft with 1 stigmatic seta, (iii) with 6-8 marginal setae between anterior and posterior stigmatic setae, (iv) antennae 6 segmented, (v) with 1 pair of submedian abdominal setae on last 3 abdominal segments, (vi) each anterior stigmatic furrow with 5-9 pores and each posterior furrow with about 8-11 pores, and (vii) with a pair of microducts between each pair of submarginal setae on abdomen. (Kondo, 2010b)
• Biology: Attended by the ant Crematogaster brevispinosa Mayr (Hempel, 1900a).Attended by the ant Azteca alfari cecropiae, in Surinam (Morrison, 1929).
• General Remarks: Good description and illustration of the adult female given by Green (1933) Morrison (1922).
