Diagnosis (female). This species is distinguished from other members of the I. suarezi species-group by the following combination of characters: vertex covered with decumbent light yellow setae (figs 21, 138), T2 with patch of light yellow setae roughly in the shape of an exaggerated “W” overlapping slightly lighter integument of the same “W” shape (figs 21, 138), and the vertical column of punctures of the mesopleuron are weakly tuberculate anteriorly and strongly tuberculate posteriorly, forming a single, crenulate carina (fig. 57).
Description (female). Body length 8.89–9.91 mm.
Head: Head 1.11–1.13 × as wide as mesosoma. Vertex and frons contiguously punctate. Antennal scrobe carina arcuate, with inner tip of carina well-separated from antennal rim.Frons transversely recessed and concave below antennal scrobe carina, antennal rim consequently recessed and barely visible when head viewed laterally. Antennal rim mostly apically glabrous, rounded and not tuberculate. F1 2.06–2.44 × as long as F2. Clypeus concave, recessed, with transverse arcuate carina complete, with small lateral tubercle ventrad to carina. Mandible acuminate. Distance from posterior margin of eye to posterolateral corner of head 1.11–1.27 × maximum diameter of eye. Genal process triangular, posterior genal carina weakly sinuate. Gena densely punctate laterally, punctures close, interpunctal space weakly microgranulate to smooth. Postgena transversely rugose-striate, with punctures between striae.
Mesosoma: Mesosoma 1.26–1.28 × as wide as long. Dorsum and posterior face of mesosoma densely, contiguously punctate, surfaces coarse. Anterodorsolateral margin of pronotum outcurved. Pronotal carina absent, with cluster of dense, contiguous, crenulate punctures in its place, simulating weak carina. Tubercle anterior of propodeal spiracle present. Width of propodeum greater than distance between propodeal spiracles in dorsal view. Lateral face of pronotum rugose-striate, interspersed with moderate punctures, lateral face posteriorly carinate along pronotalmesopleural suture. Mesopleuron microgranulate with micropunctures mostly throughout, posteriorly rugose-striate dorsad mesocoxa. Mesopleuron with vertical column of punctures tuberculate at edges, forming weak anterior and strong posterior crenulate carinae. Mesopleuron posteriorly carinate along ventral half of mesopleural-metapleural suture, carina diverging from suture roughly at midpoint and merging with dorsal carina formed by posterior tuberculate edges of vertical row of punctures, carina terminating shortly before dorsolateral margin, dorsal portion of suture faintly present as groove. Metapleuron microgranulate to smooth in areas, weakly rugose-striate dorsad metacoxa with few moderate punctures. Metapleural-propodeal suture with weak rugae perpendicularly overlapping suture along ventral one-fifth. Lateral face of propodeum mostly lightly micropunctate throughout, punctures well-separated, with moderate punctures posteriorly. Coxae coarsely sculptured, with small to moderate punctures.
Metasoma: T1–5 densely, contiguously punctate. Visible portion of pygidial plate not obscured by setal hood rugose-granulate. S2 densely punctate, punctures near contiguous in some areas, basolateral concave area less densely punctate, nearly glabrous between punctures. S3–6 densely punctate, coarsely microgranulate between punctures. Hypopygium with transverse row of setae near apical margin, lateral setae longer than median setae.
Integument coloration: Dull red-brown, except the following ranging from very dark brown-red to black: antennal rim, antenna and most or all flagellomeres, apex of mandible, pygidial plate, and apical portion of hypopygium; T2 with slightly lighter integumental pattern, corresponding with setal pattern that is roughly in shape of exaggerated “W.”
Pubescence: Frons ventrally with whitish setae, medially with few fuscous setae. Frons dorsally and vertex covered with mostly decumbent light yellow setae. Posterolateral corner of head with triangular patch of mostly decumbent black setae. Mandible with dorsal and ventral longitudinal row of light orange setae. Remainder of head with whitish setae. Dorsum of mesosoma covered with light yellow setae, with prominent ring of black setae that begins at dorsum of pronotum. Dorsal edges of mesosoma excluding most of pronotum with light yellow setae. Remainder of mesosoma including legs with whitish setae (except tarsi with orange bristles). Anterior face of T1 with whitish setae. T1 apically fringed with wide median band of black setae, laterally fringed with whitish setae. T2 medially with patch of light yellow to orange setae roughly in shape of exaggerated “W” overlapping lighter integument, tip of outer arm nearly reaching apical margin of T1, remainder of dorsum of segment with black setae. Felt line of T2 and surrounding area with whitish setae. T2 apically fringed with narrow patch of black setae medially, mostly fringed with whitish setae. T3 covered and fringed with whitish setae, medially with very few black setae. T4 similar to T3 except with more black setae medially. T5 mostly covered and fringed with black setae medially, laterally covered and fringed with whitish setae. T6 with pale orange setae surrounding pygidial plate, partially obscuring basal half. Remainder of metasoma with whitish setae.
MALE. Unknown.
