Mythenteles hispanicola Evenhuis & Blasco­Zumeta , sp. n.

( Figs. 10 , 20 )

Mythenteles n. sp. 1. Blasco­Zumeta & Melic, 1999: 41; Melic & Blasco­Zumeta, 1999: 234.

DIAGNOSIS. This species is easily separated from the congeners by the sinuous wing vein A1 (this vein straight in all other species of Mythenteles ).

DESCRIPTION. Male and female. Length: 1.15–1.51 mm. Head. Black; eyes dichoptic, separated at vertex by width of ocellar tubercle; frons slightly depressed medially, yellowish white, with brown spot medially; face yellow, clypeus brown; antennae black; scape minute; pedicel cylindrical, slightly wider than long; first flagellomere ( Fig. 10 ) ovoid, length ca. 1.5 x greatest width; second flagellomere subequal in length to first flagellomere, with relatively long apical sensillum; postgena dark brown; proboscis yellow to pale brown, thick, length slightly longer than head height; labium brown; labrum sclerotized, stiff, dark brown, pointed apically, length slightly more than height of oral margin; palpus not evident.

Thorax. Mesonotum shining black, with scattered dark hairs; humeral callus, notopleural line to wing base, thin ridge along postalar callus, propleuron, scutellum, and katepimeron yellowish white; scutellum pale brown at extreme lateral margin; coxae and legs yellow, tarsal segments II–V brown; halter stem yellow, knob creamy white.

Wing ( Fig. 20 ). Subhyaline, covered throughout with microtrichiae; veins brown; costa ends slightly less than halfway between end of R4+5 and M1; vein Sc incomplete, ending slightly less than halfway between origin of Rs and end of vein R2+3; Rs evanescent at connection with R1; R4+5 slightly curved toward wing margin; vein M1 curved toward wing margin; M2 fairly straight to wing margin; vein dm­cu closing cell dm absent; CuA1 thick; vein A1 sinuous to wing margin; fringe of hair on posterior margin of wing rather long.

Abdomen. Dorsum chocolate brown, with scattered dark hairs; thin yellow fasciate on apical margin of tergites II–VII, sometimes extending medially as posterior fasciae, especially so on apical tergites; venter paler brown than dorsum, with yellow on posterior portion of segments.

Male genitalia. Not dissected; gonocoxae brown, conspicuously subspheroid in shape; epandrium concolorous with gonocoxae, with long, pointed, posteriorly oriented epiphallic process.

Female genitalia. Not dissected.

Types. Holotype male (BPBM 15,160) and 1 paratype female from SPAIN: Zaragoza Province: Monegros: Pina de Ebro, Retuerta de Pina, 360 m, 7.vi.1991, pan traps between Juniperus thurifera and Rosmarinus sp., J. Blasco­Zumeta. Other paratype: 1 female, same data as types except: Malaise trap (USNM). Holotype and paratypes in BPBM and USNM.

Remarks. Not much variation is noted due to the paucity of known material. However, the yellow fasciae on the abdominal tergites are less pronounced or absent on the basalmost tergites of 1 specimen. The apical segments in all specimens possess these fasciae.

Etymology. The specific epithet refers to it being found only in Spain.

Distribution. Known only from Zaragoza Province in northern Spain.
