( Figs 14 , 34, 38, 40 , 70 , 86 , 101 , 117 , 131 ; Map 4)

Diagnosis (female). This species is distinguished from other members of the I. cardinalis species-group by the following combination of characters: antennal scrobe carina arcuate (figs 40, 86), antennal rim tuberculate, genal process triangular and weakly curved with posterior genal carina sinuate (figs 34, 70), with carina anterior to process weakly crenulate, anterodorsolateral margin of pronotum outcurved (fig. 101), dorsolateral margin of mesosoma, from pronotal carina to propodeal spiracle, distinctly sinuate and undulating in outline in dorsal view (fig. 101), tubercle anterior of propodeal spiracle present (fig. 101), width of propodeum greater than distance between propodeal spiracles in dorsal view (fig. 101), mesopleuron with micropunctures throughout, the interpunctal space smooth, not coarsely sculptured (figs 38, 117), and integument of dorsum of head, mesosoma, and center of T2 orange-red (figs 14, 131).

Description (female). Body length 10.54–10.67 mm.

Head: Head 1.25–1.27 × as wide as mesosoma. Vertex and frons contiguously punctate. Antennal scrobe carina arcuate, with inner tip of carina separated from antennal rim. Frons not transversely recessed and concave below antennal scrobe carina, antennal rim consequently not recessed and is visible when head viewed laterally. Antennal rim apically glabrous, tuberculate. F1 1.95–2.09 × as long as F2. Clypeus concave, with transverse arcuate carina broadly interrupted medially, area merely punctate, resulting in bilateral carinate processes each with enlarged tubercle ventrad to process. Mandible acuminate. Distance from posterior margin of eye to posterolateral corner of head 1.48–1.5 × maximum diameter of eye. Genal process triangular and weakly curved, posterior genal carina sinuate, carina anterior to process weakly crenulate. Gena densely punctate laterally, punctures large and nearly contiguous, interpunctal space smooth. Postgena transversely rugose-striate medially.

Mesosoma: Mesosoma 1.14–1.19 × as wide as long. Dorsum and posterior face of mesosoma densely, con-tiguously punctate, surfaces coarse. Anterodorsolateral margin of pronotum outcurved. Pronotal carina prominent, glabrous, weakly crenulate, visible both dorsally and laterally, not strongly protruding posteriorly in dorsal view and not entirely obscuring apical portion of pronotal-mesopleural suture. Dorsolateral margin of mesosoma, from pronotal carina to propodeal spiracle, distinctly sinuate and undulating in outline in dorsal view; tubercle anterior of propodeal spiracle present, prominent. Width of propodeum greater than distance between propodeal spiracles in dorsal view. Lateral face of pronotum rugose-striate, with moderate punctures between rugae, lateral face posteriorly carinate along pronotal-mesopleural suture. Mesopleuron with micropunctures throughout, interpunctal space smooth. Mesopleuron with vertical column of punctures not tuberculate, not forming anterior and posterior carinae. Mesopleuron posteriorly carinate along ventral half of mesopleural-metapleural suture, dorsal portion of suture absent. Metapleuron weakly rugose-striate dorsad metacoxa, with few micro- and moderate punctures, remainder of sclerite weakly microgranulate, near glabrous to glabrous. Metapleural-propodeal suture with some overlapping striae at ventral one-third and dorsal one-third. Lateral face of propodeum posteriorly and with ventral one-third rugose-striate, with moderate punctures between rugae, dorsal two-thirds weakly microgranulate, near glabrous to glabrous, medially with cluster of moderate punctures. Coxae coarsely sculptured, with small to moderate deep 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 sparsely 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 red-brown to black: antenna, antennal rim, apex and base of mandible, tip of genal process, legs including coxae and trochanters, and metasoma (excluding two conjoined orange maculae on T2).

Pubescence: Frons ventrally with whitish setae, medially with few fuscous setae. Frons dorsally and vertex mostly covered with decumbent, and some raised, orange setae, with scattered raised fuscous setae. Posterolateral corner of head with sparse patch of 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 raised fuscous setae. Pronotum with dorsal transverse band of black setae, except area between epaulet and pronotal spiracle with whitish 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 conjoined orange integumental maculae, with maculae anteriorly and posteriorly surrounded with black setae. Felt line of T2 and surrounding lateral area with whitish setae. T2 apically fringed with wide band of black setae medially, laterally fringed with whitish setae. T3 covered and fringed with whitish setae, few scattered raised fuscous setae present. T4 similar to T3 except with patch of black setae medially. T5 mostly covered and fringed with black setae medially, laterally fringed with whitish setae. T6 with 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 type locality of Cuernavaca, Morelos, Mexico.

Distribution: Mexico (Morelos).

Biogeography: Neotropical region (Balsas Basin province).

Host(s): Unknown.

Remarks: This species is known only from the holotype and a paratype, which share the same collection data. It is apparently closely related to I. cardinalis , which also occurs in Cuernavaca. Both species share a posteriorly sinuate genal carina, an outcurved anterodorsolateral margin of pronotum, a sinuate and undulating dorsolateral margin of mesosoma in dorsal view, and a propodeal width greater than distance between propodeal spiracles in dorsal view.
