Diagnosis. Head with wrinkle-like sculpture dorsally, but becoming smooth ventrally. Mesoscutum and mesoscutellum, including axillula, areolate. Mesoscutal sidelobes strongly protruding.
No other species in this group has a similar face (Fig. 132). This species is also distinctive in having strongly protruding mesoscutal sidelobes (Fig. 134), but this is an apparently variable feature in some other species.
Description. Female. Length 3.1 mm.
Color: Head and mesosoma blue to green, with yellow luster. Pedicel pale brown; anellus pale brown; flagellum brown. Coxae brown; fore femur mostly brown, tips pale; mid and hind femora yellow. Fore wing hyaline; venation brown. Petiole blue to purple; gaster brown with purple luster.
Head: Head width:head height 1.2; face reticulate with wrinkle-like sculpture dorsally, becoming smooth ventrally; longitudinal groove between eye and torulus present; eyes bare, inter-ocular distance:eye height 1.8; malar space:eye height 0.9; supraclypeal area longer than broad, mostly smooth but with weak sculpture laterally; clypeus smooth to weakly sculptured. Flagellum length:head height 1.9; F2 2.9× as long as broad, 1.0× as long as F3; following funiculars progressively shorter and broader.
Mesosoma: Mesosoma length:height 1.4. Mesoscutal midlobe areolate-reticulate, with minute setae; lateral lobe areolate-reticulate. Axilla areolate-reticulate; mesoscutellar disc areolate; frenal line irregularly foveate; frenum areolate; axillular groove anteriorly narrow, broad and foveate posteriorly; axillula areolate. Propodeum with irregular median carina; propodeal disc areolate to areolate-reticulate; callus areolate-reticulate, with 3–5 setae. Mesepisternum reticulate to areolate-reticulate laterally, smooth ventrally, broadly rounded anterior to mid coxa. Upper mesepimeron smooth; lower mesepimeron areolate-reticulate; transepimeral sulcus distinct. Metepisternum smooth dorsally, areolate-reticulate ventrally. Hind coxa 2.1× as long as broad; hind femur 6.7× as long as broad. Fore wing 1.9× as long as broad, 2.0× as long as mesothorax; stigma with 4 sensilla forming an Lshape. Hind wing costal cell with a broad bare area.
Metasoma: Petiole 5.2× as long as broad, 1.8× as long as hind coxa, areolate, anterior carina moderate. Antecostal sulcus crossed by carinae; acrosternite posteriorly angulate.
Male. unknown.
Distribution. Guatemala.
Material examined. Holotype: GUATEMALA: Sierra Caral, 19 km. S.E. Morales, 1180m, 15°21'52"N, 88°41'28"W [1 ♀, UCRCENT 00479120], deposited in UCRC.
Etymology. After the Quechua word mat’i, meaning “forehead,” referring to the relatively smooth face.
