Dermatopelte sinaloensis n. sp.

Diagnosis. Vertex weakly carinate behind ocellar triangle (Fig. 4). Petiole 1.45x longer than broad in females (Fig. 6), 1.67x in males, its apex not reaching metacoxal apex in females. First funicular segment 2.33x longer than broad ( Fig. 1 ). Scape at rest not extending above median ocellus ( Fig. 1 ).

Description. Female holotype: Body length 2mm (10.9 in relative units used below).

Color: Head and mesosoma dark reddish­brown, with shallow elevation between toruli and clypeal area slightly lighter in color. Eye gray, ocellus whitish. Mandible light brown, palp yellow. Most of scape yellow, but slightly darker at apex dorsally. Pedicel light brown. Flagellum brown with white longitudinal sensilla. Setae golden. Legs almost entirely pale yellow, including coxae, but metatibia slightly infuscate at apex. Venation yellow. Metasoma: petiole and gaster mostly yellow, but gaster brownish in dorsal posterior half and sublaterally in anterior half.

Sculpture: Head mostly glossy and smooth, except vertex (Fig. 5) and areas lateral and dorsal to antennal scrobe coriaceous­reticulate; vertex carinate behind ocellar triangle (Fig. 4), no postoccipital carina. Mesosoma ( Figs. 1 , 5): Pronotal collar densely rugose, coriaceous­reticulate between the rugae. Mesoscutal midlobe, scutellar disc, and axillae regularly coriaceous­reticulate with narrowly separated ovate meshes. Mesoscutal sidelobes transversely rugulose, with setae arising from relatively smooth raised pustules. Scutellum with a vaguely defined impression medially just posterior of scutellar midpoint. Sublateral grooves of scutellum broad and foveate, regularly crossed by small carinae. Axillae and mesothoracic venter glossy and smooth. Exposed dorsal portion of prepectus glossy and sparsely rugose. Mesopleuron smooth except for the acropleural, mesopleural, and transepimeral sulci, and transepisternal division formed by a carina along its ventral length. Basal semicircular area of dorsellum rugose, with periphery more nearly foveate. Propodeum densely transverse­rugose (Figs. 5, 6), median carina with an anterior split. Metapleuron divided into deep foveae. Petiole longitudinal­rugose (Fig. 6). Gaster smooth ( Fig. 1 ).

Head ( Figs. 1 , 5) width 3.35, height 2.4, length 1.3. Toruli separated by a shallow, rounded, gradually defined elevation, their bottom margins intersecting the lower eye margin; intertorular distance 0.4 (in the relative units). Ocular setae short, equal in length to the diameter of an adjacent ommatidium. Clypeus not indicated. Eye height 1.5, malar space 0.8, mouth width 0.9, gena length 0.2, POL 0.8, OOL 0.4, temples extremely short. A radial row of long setae arising from back of head, the setae extending towards the periphery and generally visible from facial view (as in Fig. 10). Hypostomal bridge formed. Scape 1.4x0.2, pedicel 0.5x0.3, anellus 0.05x0.2, 1st funicular segment 0.7x0.3, 2nd 0.5x0.3, 3rd 0.55x0.35, 4th 0.45x0.3, club 1.0x0.4. Scape not quite reaching median ocellus, ventrally carinate. Funicular segments with 2 rows of sparse longitudinal sensilla, claval segments with 1 row. Club 3­segmented, with a terminal spine. Malar sulcus complete but extremely faint. Mandible not divided into denticles, not capable of reaching other mandible medially, with a row of 3 long setae along mid­height. Maxillary palp 2­ segmented, apical with one long apical seta, a short subapical seta directed opposite to the apical one, and a long seta basal to these and parallel to the shortest seta. Labial palp 1­ segmented, with two long apical setae.

Mesosomal length 4.8 ( Figs. 1 , 5). Pronotum 1.3x2.6, mesoscutum 1.3x3.5, scutellum 1.8x1.8, dorsellum 0.4x1.4, propodeum 1.3x3.0. Pronotal collar not carinate anteriorly, only vaguely separated from collum, laterally carinate along its entire length; pronotal scrobe longitudinal, broad, and shallow, very poorly defined. Mesoscutal midlobe with two longitudinal submedial rows of 3 pairs of long setae, another pair of setae anterior and medial to these, and several smaller paired setae lateral to the rows. Axilla slightly advanced, antero­medially separated from mesoscutum and scutellum by a narrow sulcus. Axillula large, half as long and over half as tall as scutellum. Dorsellum pentagonal/semicircular, with vague posterior edges. Propodeal callus with 10–11 setae almost entirely in a straight, regular row from base to apex, with a few of these setae medial to this row at propodeal base. Exposed portion of prosternum long, with a large anterior fovea outlined by a deep, nearly translucent carina (as in Fig. 11). Procoxa 1.3x0.7, profemur 2.3x0.6, protibia 2.2x0.3, protarsal length 1.8, apical protarsomere slightly longer than the others. Mesocoxa 0.7x0.8, mesofemur 2.4x0.4, mesotibia 3x0.4, mesotarsal length 1.8, apical mesotarsomere slightly longer than the others. Metacoxa 1.7x0.8, metafemur 3.0x0.8, metatibia 3.1x0.4, metatarsal length 2.2, apical metatarsomere slightly longer than the others. Forewing 9.4x4.3, costal cell 3.1x0.3, marginal vein length 2.7, postmarginal vein 1.5, stigmal vein 0.75. Uncus equal to greatest stigmal width, with uncal sensilla in a straight row. Costal cell with 2 complete rows of ventral setae and an antero­apical row of 4–5 dorsal setae that begins past the midpoint of the cell. Basal fold setose, and basal cell bare except for a ventral row of regularly spaced setae anteriorly. Cubital setal line absent from basal 3/4 of basal cell. Speculum present but small, extending from apex of premarginal vein to be completely closed posteriorly by the cubital setal line. Two rows of long admarginal setae present along the entire admarginal area, most not exposed by speculum. Radial cell setose. Hind wing 7.4x1.6.

Petiole 0.8x0.55 (Fig. 6), gaster 4.5x2.3, ovate ( Fig. 1 ). Petiole parallel­sided, falling distinctly short of metacoxal apex. Gastral base with a very weak dorso­lateral carina on each side of the petiolar base, bordered medially by a narrow fovea, these extending for 0.3 from petiolar base. First gastral tergite 0.2x gastral length, truncate posteriorly. Hypopygium reaching 0.8x gastral length, with a deep apical vase­shaped incision with rounded contours. Cercus with 1 seta distinctly longer than the others, with a sharp apical curve.

Male allotype: Body length 2.13mm (11.5 in relative units). Similar proportionally to female except for the following. Scape length x width 1.3x0.2, with a small protruding ovate sensory area subapically, pedicel 0.4x0.25, anellus 0.05x0.2, each funicular segment with 1 row of longitudinal sensilla and longer and more curved flagellar setae, first funicular segment 0.6x0.3, 2nd 0.5x0.3, 3rd 0.4x0.4, 4th 0.4x0.4, club 0.9x0.3. Petiole 1.0x0.6 and reaching metacoxal apex. Gaster with both a dorsal and a ventral pale subbasal blotch and otherwise brownish. Costal cell with two rows of ventral setae, dorsal row of costal cell setae beginning at midpoint of cell and composed of 8 setae. Scutellar disc rugulose. All femora and coxae brownish, and entire hind leg brownish. Apical gastral sternite (Fig. 3) concave and strongly sclerotized beneath genital capsule.
