Morphology
The description below is paraphrased from the original or a later revision, by caste; the source is cited at the end.
Diagnostic characters
The enteric valve armature consists of 6 groups of pectinate spine bundles, each with 4–6 rows of spines: longer spines distally near P3, decreasing posteriorly, together with smaller tooth-like spines; the proximal end of each pad (near P1) bears 1 small tooth-like spine; the enteric valve is inserted directly into P3 without a differentiated enteric valve seat (EVS). On this basis it is distinguished from Patawatermes (enteric valve seat drawn out into a tube, clearly visible externally) and Echinotermes (enteric valve seat trilobed). The external gut morphology resembles Hydrecotermes, but the enteric valve of the latter is unarmed. The generic name refers to the sea-urchin-like appearance of the enteric valve armature (Portuguese ouriço).
Alate
Head slightly concave above the ocelli; fontanelle very small or indistinct; compound eye and ocellus nearly round; antennal segments 15 (segment pattern 2>3<4<5<6); lateral margins of the pronotum elongate and smoothly rounded.
Worker
Anterior part of the dorsal surface of the head capsule slightly convex in profile; postclypeus strongly inflated; antennal segments 14. Apical tooth of the left inner mandible more projecting than M1+2, the margin of M3 forming an obtuse-angled triangle with a slightly truncate tip, the molar prominence well developed, partly concealing the molar lobe process; apical tooth of the right inner mandible more projecting than M1, M2 triangular with an acute angle, its tip projecting but slightly less than M1. Gut: midgut tongue small, P1 joined to the midgut by a simple transverse connection; enteric valve seat indistinct; enteric valve armature as in the genus diagnosis (6 groups of pectinate spine bundles, the distal spines long and decreasing posteriorly).
This genus is monotypic, containing only this species; the following is the genus-level description based on the original literature; species-level measurements and intraspecific variation are given in the original.

- Diminishing the taxonomic gap in the neotropical soldierless termites: descriptions of four new genera and a new Anoplotermes species (Isoptera, Termitidae, Apicotermitinae)
Abstract
The neotropical Apicotermitinae is a common and widespread clade of mostly soil-feeding soldierless termites. With few exceptions, species of this group were originally assigned to the genus Anoplotermes Müller, 1873. The application of internal worker morphology coupled with genetic sequencing has recently shed light on the true diversity of this subfamily. Herein, Anoplotermes susanae Scheffrahn, Carrijo & Castro, sp. nov. and four new species in four new genera are described: Hirsutitermes kanzakii Scheffrahn, Carrijo & Castro, gen. nov. et sp. nov., Krecekitermes daironi Scheffrahn, Carrijo & Castro, gen. nov. et sp. nov., Mangolditermes curveileum Scheffrahn, Carrijo & Castro, gen. nov. et sp. nov., and Ourissotermes giblinorum Scheffrahn, Carrijo & Castro, gen. nov. et sp. nov. Worker descriptions are based mainly on worker gut morphology, including the enteric valve, while imagoes were described based on external characters. A Bayesian phylogenetic tree of New World Apicotermitinae was constructed using the complete mitogenome to infer genera relationships and corroborate the taxonomic decisions. Distribution maps and a dichotomic key to the known Neotropical Apicotermitinae genera are provided.
