Diagnosis (female). This species is distinguished from the other member of the I. cephalargia species-group, I. cephalargia , by the following combination of characters: the vertex is mostly covered with decumbent orange setae (figs 16, 133), the dorsum of T2 without a central patch/patches of golden setae, mostly covered with orange-red setae (figs 16, 133), the integument of the antennae, pleura, and legs is dark red-brown (figs 16, 88, 119, 133), and the striations of the meso- and metapleura and lateral face of propodeum more pronounced (figs 61, 119).

Description (female). Body length 7.49–8.76 mm.

Head: Head 1.12–1.22 × as wide as mesosoma. Vertex and frons contiguously punctate. Antennal scrobe carina moderately arcuate, with inner tip of carina well-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, weakly tuberculate. F1 1.6–1.82 × 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 1.18–1.64 × maximum diameter of eye. Genal process triangular, posterior genal carina nearly straight. Gena densely, contiguously punctate laterally. Postgena transversely rugose-striate.

Mesosoma: Mesosoma 1.09–1.18 × as wide as long. Dorsum and posterior face of mesosoma densely, contiguously punctate, surfaces coarse. Anterodorsolateral margin of pronotum outcurved. Pronotal carina obscurely present, with cluster of dense, contiguous punctures in its place, edges of punctures tuberculate and crenulate, simulating 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, with moderate punctures amid striae, lateral face posteriorly carinate along pronotal-mesopleural suture. Mesopleuron finely striate-rugose anteriorly, microgranulate and with micropunctures, posteriorly striate-rugose. Mesopleuron with vertical column of punctures tuberculate at edges, forming crenulate anterior and posterior carinae. Mesopleuron posteriorly carinate along ventral half of mesopleural-metapleural suture, dorsal portion of suture obscure. Metapleuron with ventral half striaterugose, dorsal half microgranulate and nearly glabrous. Metapleural-propodeal suture with short striae perpendicularly overlapping suture mostly throughout its length, dorsal third of suture overlapped by deep punctures or grooves between striae. Lateral face of propodeum with ventral two-thirds striate-rugose, dorsal one-third microgranulate to striate-rugose, with few moderate punctures. Coxae coarsely sculptured, with small to large punctures.

Metasoma: Dorsum of T1–5 densely, contiguously punctate. Visible portion of pygidial plate not obscured by setal hood rugose-granulate to transversely rugose-granulate. S2 densely punctate, punctures moderate, interpunctal space smooth, 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: Frons, vertex, gena, venter of head, basal 2/3 of mandible, dorsum of mesosoma, lateral face of pronotum, most of T2, and middle of S2, orange, with remaining integument dark red-brown.

Pubescence: Frons ventrally with whitish setae, medially with few fuscous setae. Frons dorsally and vertex mostly covered with decumbent and raised orange-red setae, with scattered raised fuscous setae. Clypeus with fuscous and whitish setae. 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, dorsal edges (except pronotum) with sparse raised fuscous setae. Pronotum without black setae, rather with orange setae. Posterior face of propodeum with black setae. Remainder of mesosoma including legs with whitish setae (except tarsi with dense orange bristles). Anterior face of T1 with black setae. T1 apically fringed with wide band of black setae medially, laterally fringed with whitish setae. T2 dorsally covered with decumbent orange setae, anteriorly with transverse band of black setae overlapping with T1 apical fringe, posteriorly with transverse band of black to whitish setae before apical fringe. Felt line of T2 and surrounding lateral area with whitish setae. T2 apically fringed with sparse median patch of black setae, laterally fringed with whitish setae. T3–5 covered with pale and some raised fuscous setae, mostly fringed with whitish setae, medially with small patch of black setae. T6 with light yellow-orange setae surrounding pygidial plate, partially obscuring basal half. Remainder of metasoma with whitish setae.

MALE. Unknown.

Etymology: This species is named in honor of Dr. Donald G. Manley in recognition of his contributions to mutillid systematics and biology since the 1970s. Dr. Manley also collected one of the paratypes in Hidalgo Co., New Mexico, the first record of Invreiella for the state.

Distribution: Mexico (Chihuahua); USA (Arizona and New Mexico).

Biogeography: Nearctic region (Chihuahuan Desert province); Mexican transition zone (Sierra Madre Occidental province).

Host(s): Unknown.

Remarks: This is the second known female-based Invreiella species from the United States (after I. cephalargia ).
