description: 14. Invreiella tequila Waldren, sp. nov.
(Figs 22, 43, 48, 50, 56, 58, 59, 78, 94, 109, 125, 139; Map 7)
Diagnosis (female). This species is distinguished from other members of the I. suarezi species-group by the following combination of characters: frons and part of vertex with a large central patch of black setae surrounded by decumbent coppery-orange setae on the vertex (figs 22, 139), 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 22, 139), and the vertical column of punctures of the mesopleuron are strongly tuberculate both anteriorly and posteriorly, forming parallel, crenulate carinae bounding the punctures (fig. 58). Lastly, it is distinguished from all other Invreiella by its medioapically expanded mandible, with the dorsal carina preceding the middle tooth and the ventral carina both expanded (fig. 59).
Description (female). Body length 11.94–12.57 mm.
Head: Head 1.04–1.07 × 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 apically glabrous, rounded and not tuberculate. F1 2.14–2.39 × as long as F2. Clypeus concave, recessed, with transverse arcuate carina complete, with small lateral tubercle ventrad to carina. Mandible medioapically expanded in width, with both dorsal carina preceding middle tooth and ventral carina expanded. Distance from posterior margin of eye to posterolateral corner of head 1.44–1.65 × maximum diameter of eye. Genal process triangular, posterior genal carina weakly sinuate. Gena densely punctate laterally, punctures close, nearly contiguous, interpunctal space smooth. Postgena transversely rugose-striate, with punctures between striae.
Mesosoma: Mesosoma 1.22–1.29 × 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 obscure. Width of propodeum greater than distance between propodeal spiracles in dorsal view. Lateral face of pronotum rugose-striate, interspersed with moderate punctures, microgranulate, lateral face posteriorly carinate along pronotal-mesopleural suture. Mesopleuron coarsely microgranulate, with scattered small punctures, posteriorly rugose-striate dorsad mesocoxa. Mesopleuron with vertical column of punctures strongly tuberculate anteriorly and posteriorly, forming parallel, crenulate carinae bounding the punctures. Mesopleuron posteriorly carinate along ventral half of mesopleural-metapleural suture, carina diverging from suture roughly at midpoint and near seamlessly merging with dorsal carina formed by posterior tuberculate edges of vertical row of punctures, carina continuing to and terminating at dorsolateral margin of mesosoma, dorsal portion of suture present, although weakly, and terminating at tubercle anterior to propodeal spiracle. Metapleuron with dorsal half obscurely microgranulate with few micropunctures, ventral half micropunctate, rugose-striate dorsad metacoxa with few moderate punctures. Metapleural-propodeal suture with rugae perpendicularly overlapping suture along ventral one-third. Lateral face of propodeum posteriorly with ventral one-third striate-rugose with few moderate punctures, anteriorly with dorsal two-thirds microgranulate with micropunctures and few moderate punctures. 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 to 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 micropunctate between punctures. Hypopygium with slightly arcuate 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, 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 part of vertex with large central patch of black setae, surrounded by coppery-orange setae on the vertex. 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 mostly covered with black setae, with median patch of light yellow setae. Area between epaulet and pronotal spiracle with light yellow setae. Dorsal face of propodeum laterally 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 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 covered with black setae. Felt line of T2 and surrounding lateral area with whitish setae. T2–4 apically fringed with moderately wide median patch of black setae, laterally fringed with whitish setae. T5 mostly covered and fringed with black setae medially, laterally covered and fringed with whitish setae. T6 with pale orange to yellow 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 Tequila, Jalisco, Mexico.
Distribution: Mexico (Jalisco and Morelos).

Host(s): Unknown.
Remarks: This species is only known from the Mexican states of Jalisco and Morelos, with two of the four known specimens collected in and around the city of Tequila, Jalisco.
