Burks, Roger A., 2004, Dermatopelte Erdös & Novicky (Hymenoptera: Eulophidae) newly recorded from the Nearctic region, with description of two new species, Zootaxa 407 (407), pp. 1-10 : 7-9

Dermatopelte yanegai sp. nov.

Diagnosis. Vertex weakly carinate behind ocellar triangle (as in Fig. 4). Petiole 2.45x longer than broad (Fig. 8), its apex reaching metacoxal apex. First funicular segment 3x longer than broad (Fig. 7). Scape at rest slightly exceeding vertex height (Figs. 7, 10).

Description. Female holotype: Body length 2.3mm (12.4 in relative units used below).

Color: Head dark brown, with shallow elevation between toruli slightly lighter in color. Eye gray, ocellus whitish. Mandible and palp very pale whitish­yellow. Most of scape yellow, but apical 0.4 gradually becoming brownish. Pedicel brownish except for yellow at extreme apex. Flagellum brown with white longitudinal sensilla. Most of body pale orange, with no hint of metallic luster, but anterior margin of pronotal collar dark brown and gaster nearly yellow. Setae golden. 3rd valvula dark brown. Legs almost entirely pale yellow, including coxae, but metatibia gradually becoming brown in its apical 0.4, metatarsus, protarsus, and apical mesotarsomere brown. Venation brown.

Sculpture: Head (Figs. 9, 10) mostly glossy and smooth, except vertex and areas lateral and dorsal to antennal scrobe coriaceous­reticulate; vertex carinate behind ocellar triangle (as in Fig. 4), no postoccipital carina. Mesosoma (Figs. 7, 9): Pronotal collar with a strong anterior transverse ruga and several longitudinal rugae, 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 shallow, vaguely defined impression medially just posterior of scutellar midpoint. Sublateral grooves of scutellum broad and foveate, regularly crossed by small carinae. Exposed dorsal portion of prepectus glossy and sparsely rugose. Axillula glossy and smooth. Mesopleuron and mesothoracic venter 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 (Fig. 8), median carina with an anterior split. Metapleuron divided into deep foveae. Petiole longitudinal­rugose (Fig. 8). Gaster smooth (Fig. 7).

Head (Figs. 7, 9, 10) width 3.7, height 2.4, length 1.7. 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 0.9, mouth width 1.0, gena length 0.2, POL 0.7, OOL 0.5, 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 (Fig. 10). Hypostomal bridge formed. Scape 1.8x0.3, pedicel 0.6x0.3, anellus 0.05x0.2, 1st funicular segment 0.9x0.3, 2nd 0.6x0.4, 3rd 0.6x0.4, 4th 0.6x0.4, club 1.0x0.4. Scape ventrally carinate, apex slightly exceeding vertex height. Funicular segments with 2 rows of sparse longitudinal sensilla, claval segments with 1 row. Club 3­segmented, with a terminal spine. Malar sulcus complete but faint. Mandible not divided into denticles, not capable of reaching other mandible medially, with a row of three long setae along its mid­height. Maxillary palp 2­segmented, 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 1­segmented, with two long apical setae.

Mesosomal length 5.8 (Figs. 7, 9). Pronotum 0.9x2.8, mesoscutum 1.5x3.6, scutellum 1.9x1.8, dorsellum 0.6x1.4, propodeum 1.5x3.3. Pronotal collar with a strong ruga forming an abrupt anterior margin, shoulder laterally carinate along its entire length; pronotal scrobe shallow and broad, longitudinal. 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 not advanced, separated anteromedially from mesoscutum and scutellum by a broad undivided fovea; axillar separation 0.4. Axillula large, half as long and over half as tall as scutellum. Dorsellum pentagonal/ semicircular, with vague posterior edges. Propodeal callus with 14–16 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 (Fig. 11). Procoxa 1.3x0.7, profemur 2.9x0.7, protibia 2.7x0.4, protarsal length 2; apical protarsomere slightly longer than the others. Mesocoxa 1.1x0.7, mesofemur 3.0x0.5, mesotibia 3.6x0.35, mesotarsal length 1.8; apical mesotarsomere slightly longer than the others. Metacoxa 1.7x1.0, metafemur 3.6x0.8, metatibia 4.1x0.4, metatarsal length 2.7, with 2nd metatarsomere slightly longer than the others. Forewing 11.5x4.8, costal cell 3.9x0.35, marginal vein length 3.0, postmarginal vein 1.9, stigmal vein 1.0. Uncus length 0.5x greatest stigmal width, with uncal sensilla in a straight row. Costal cell with three 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. Three rows of long admarginal setae present along the entire admarginal area, most not exposed by speculum. Radial cell setose. Hind wing 8.9x2.0.

Petiole 1.6x0.65, gaster 4.9x3.3, ovate (Fig. 7). Petiole broadest posteriorly, extending to metacoxal apex. Gastral base with a dorso­lateral carina on each side of the petiolar base, bordered medially by a narrow fovea, these extending for 0.6 from petiolar base. First gastral tergite 0.2x gastral length, truncate posteriorly. Hypopygium reaching 0.7x gastral length, with a deep apical vase­shaped incision with rounded contours. Cercus with no seta distinctly longer than the others (this would be unique in the genus, but it is possible that the long setae have been broken off in this specimen).

Types : Holotype ♀ with label data: USA: Arizona: Pima Co. Box Canyon. 1465m. MV. 31º47 53 N 110º46 38 W. 22­vii­2000. D. Yanega. Swept from vegetation consisting mostly of Baccharis sp. (D. Yanega, pers. comm.). Deposited in USNM.

Etymology: This species is named in honor of the collector, my friend Doug Yanega, curator at the University of California, Riverside Entomological Research Museum. The specific epithet should be pronounced with stress on the first syllable.
