Diagnosis (female). This species is distinguished from other members of the I. suarezi species-group by the following combination of characters: vertex, mesosoma, and T2 covered mostly with decumbent orange-red setae (figs 20, 137), T2 without a distinct dorsal setal pattern (figs 20, 137), and the vertical column of punctures of the mesopleuron are weakly tuberculate anteriorly and prominently tuberculate posteriorly, forming a single, crenulate carina (i.e. fig. 57).
Description (female). Body length 11.18 mm.
Head: Head 1.13 × as wide as mesosoma. Vertex and frons contiguously punctate. Antennal scrobe carina arcuate, with inner tip well-separated from antennal rim. Frons strongly transversely recessed and concave below antennal scrobe carina, antennal rim consequently recessed and not visible when head viewed laterally. Antennal rim apically glabrous, rounded and not tuberculate. F1 2.2 × 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 1.6 × maximum diameter of eye. Genal process triangular, posterior genal carina weakly sinuate. Gena densely punctate laterally, punctures close, interpunctal space smooth. Postgena transversely rugose-striate.
Mesosoma: Mesosoma 1.3 × 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 pronotal-mesopleural suture. Mesopleuron mostly covered with micropunctures, interpunctal space smooth, weakly rugose-striate posteriorly dorsad middle coxa. Mesopleuron with vertical column of punctures tuberculate at edges, forming weak anterior and strong posterior crenulate carinae. Mesopleuron posteriorly carinate along ventral half of mesopleuralmetapleural 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 obscure, faintly present at groove halfway to dorsolateral tubercle and absent remaining distance to tubercle. Metapleuron with dorsal half mostly glabrous, ventral half with some micropunctures and moderate punctures. Metapleural-propodeal suture with rugae perpendicularly overlapping suture along ventral one-fourth. Lateral face of propodeum mostly 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 slightly arcuate transverse row of setae near apical margin, lateral setae longer than median setae.
Integument coloration: Orange, except the following ranging from dark brown-red to black: antenna, antennal rim, base of clypeus, apex of mandible, lateral and posterior face of propodeum, legs excluding most of femora and coxae, and metasoma (except T2 mostly covered with two large coalescing orange maculae).
Pubescence: Frons ventrally with whitish setae, medially with few fuscous setae. Frons dorsally and vertex with mostly decumbent and some raised orange-red setae. Posterolateral corner of head with scattered raised fuscous setae. Mandible with dorsal and ventral longitudinal row of light orange setae. Remainder of head with whitish setae. Dorsum of mesosoma mostly covered with decumbent orange-red setae, dorsolateral edges with sparse raised fuscous setae. Pronotum with dorsal transverse band of black setae, except area between epaulet and pronotal spiracle with few whitish setae. Dorsum of propodeum with inconspicuous longitudinal row of black 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 with decumbent orange setae overlapping large coalescing orange integumental maculae, remainder of dorsum of T2 with red-brown to black setae surrounding maculae, with asetose punctate patch of integument present just posterior to middle of maculae, surrounded by red-brown setae. Felt line of T2 and surrounding lateral area with whitish setae. T2 apically fringed with narrow median patch of dark red-brown setae, laterally fringed with whitish setae. T3 covered and fringed with whitish setae, medially with few red-brown setae. T4 covered and fringed with red-brown setae medially, with whitish setae laterally. T5 mostly covered and fringed with black setae medially, with whitish setae laterally. T6 with dark orange setae surrounding pygidial plate, partially obscuring basal half. Remainder of metasoma with whitish setae.
MALE. Unknown.
Etymology: The specific epithet is derived from the Greek erythraios and kephale in reference to the reddish head that helps distinguish this species from the other two members of the I. suarezi species-group.
Distribution: Mexico (Morelos).
Biogeography: Neotropical region (Balsas Basin province).
Host(s): Unknown.
Remarks: This species is known only from the holotype. The collection locality for this specimen of “ Puebla: 11km NW. of Tepexco” actually places it just within the state boundary of Morelos.
