Diagnosis (female). This species is distinguished from other members of the I. australis species-group by the following combination of characters: antennal scrobe carina straight (figs 44, 81), genal process triangular with posterior genal carina sinuate (fig. 65), lateral face of pronotum with moderate punctures mostly throughout (fig. 112), integument of head black at posterolateral corners, gena, and occiput, with integument of frons and part of the vertex orange (figs 9, 65, 126), and T2 with two pale yellow integumental spots that are separate and not coalescing, with the remaining dorsal integument of T2 black (figs 9, 126).
Description (female). Body length 10.92 mm.
Head: Head 1.26 × as wide as mesosoma. Vertex and frons contiguously punctate. Antennal scrobe carina straight, with inner tip of carina close to 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 and protruding. F1 2.17 × as long as F2. Clypeus concave, 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 1.41 × maximum diameter of eye. Genal process triangular, posterior genal carina sinuate. Gena densely punctate laterally, interpunctal space smooth. Postgena transversely rugose-striate.
Mesosoma: Mesosoma 1.19 × as wide as long. Dorsum and posterior face of mesosoma densely, contiguously punctate, surfaces coarse. Anterodorsolateral margin of pronotum outcurved. Pronotal carina prominent, glabrous, crenulate due to overlapping lateral punctures, visible both dorsally and laterally, not strongly protruding posteriorly in dorsal view and not entirely obscuring dorsal portion of pronotal-mesopleural suture. Tubercle anterior of propodeal spiracle present, prominent. Width of propodeum greater than distance between propodeal spiracles in dorsal view. Lateral face of pronotum with moderate separated punctures throughout, interpunctal space microgranulate with micropunctures, lateral face posteriorly carinate along pronotal-mesopleural suture. Mesopleuron microgranulate with micropunctures mostly throughout. Mesopleuron with vertical column of punctures weakly tuberculate, not forming anterior or posterior carinae. Mesopleuron posteriorly carinate along ventral half of mesopleural-metapleural suture, carina diverging from suture roughly at midpoint and terminating shortly after, dorsal portion of suture obscure, present as faint groove. Metapleuron with scattered micropunctures, weakly rugose-striate just dorsad metacoxa, with few moderate punctures. Metapleural-propodeal suture without overlapping striae. Lateral face of propodeum with scattered moderate punctures, especially medially and posteriorly, with few clusters of micropunctures and microstriae. Coxae coarsely sculptured, with small to moderate punctures.
Metasoma: T1–5 densely, contiguously punctate. Visible portion of pygidial plate not obscured by setal hood transversely rugose-granulate. S2 densely punctate, punctures large, interpunctal space smooth, basolateral concave area sparsely punctate, nearly glabrous between punctures. S3–6 densely punctate, coarsely microgranulate between punctures. Hypopygium with arcuate row of setae near apical margin, lateral setae longer than median setae.
Integument coloration: Frons, median triangular section of vertex, mesosoma, tibiae, and tarsi dull red-orange, with two pale yellow maculae on T2 that are separate and not coalescing, remaining dark brown-red to black: posterolateral corner of head, gena, postgena, antennal rim, antenna, apical half and basal quarter of mandible, base of clypeus, coxae, trochanters, femora, and metasoma.
Pubescence: Frons ventrally with whitish setae, medially with few fuscous setae. Frons dorsally and median triangular section of vertex covered with mostly decumbent orange setae overlapping orange integument. Posterolateral corner of head with triangular patch of mostly decumbent black setae overlapping nearly black integument. Mandible with dorsal and ventral longitudinal row of pale orange setae. Remainder of head with whitish setae. Dorsum of mesosoma mostly covered with decumbent orange setae, dorsolateral edges with sparse raised fuscous setae.
Pronotum with dorsal transverse band of black setae, except area between epaulet and pronotal spiracle with whitish setae. Median patch of decumbent black setae present on dorsum of propodeum and just anterior to it. Remainder of mesosoma including legs with whitish setae (except tarsi with dense orange bristles). Anterior face of T1 with whitish setae. T1 apically fringed with moderately wide band of black setae medially, laterally fringed with whitish setae. T2 with decumbent light yellow setae overlapping two yellow integumental maculae, remainder of dorsum of T2 with black setae surrounding maculae. 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. T4 similar to T3 except with small patch of black setae medially. T5 mostly covered and fringed with black setae medially, laterally fringed with whitish setae. T6 with light 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 Latin australis in reference to this species being the southernmost member of Invreiella .
Distribution: Mexico (Chiapas, Oaxaca).
Biogeography: Mexican transition zone (Chiapas Highlands province, Sierra Madre del Sur province).
Host(s): Unknown.
Remarks: This species is the only member of Invreiella known to occur east of the Isthmus of Tehuantepec.
