No full textCyrtosia persica Gharali & Evenhuis Cyrtosia persica Gharali & Evenhuis, 2011: 152. Material examined. 2 males, 3 females, Juladak village, 36°21'49.2'' N, 50°32'13.4'' E, 2357 m a.s.l., 12 July 2008, swept from Cichorium intybus L. (Asteraceae), leg. Babak Gharali (BG). Diagnosis. This species is easily recognized from the congeners in Iran by the yellow frons with a tiny black spot medially. Other species have either an almost all black frons or a black stripe medially on the frons. Remarks. This species is known only from the Alamot region of Qazvin province.

Mythenteles rigirostris Evenhuis
No full textMythenteles rigirostris (Evenhuis) (Figs. 15, 24) Mythicomyia rigirostris Evenhuis, 1981: 6. Evenhuis, 1983: 487. Mythenteles rigirostris (Evenhuis). Evenhuis, 2002 b: 36. Reexamination of the unique type of Mythicomyia rigirostris showed characters that required that it be transferred to Mythenteles, which was done by Evenhuis (2002 b). The wing venation, which was somewhat obscured when originally described, has been repositioned to give a more clear view and reveals a distinct vein M separating the cells br and bm plus a distinct vein A 1 reaching the wing margin. The genitalia have not been dissected due to the paucity of material at hand. The external characters should serve to easily separate it from the congeners. Very little can be added to the original description and it is reproduced here with a more detailed description of the wing venation. Material additional to or modified from the original description are placed in brackets. DESCRIPTION. Female (Fig. 24). Length: 1.33 mm. Head. [Eyes dichoptic]; “as in asiatica; proboscis extending beyond oral margin, equal in length to entire body. Thorax. Black, gray pollinose; scutellum brown with yellow laterally; otherwise as in asiatica. Legs: yellow, tarsi brown. Wing. [(Fig. 15) Hyaline, veins brown; costa ends slightly beyond end of vein R 4 + 5; 4 posterior cells; Sc incomplete; rm crossvein at basal 1 / 4 of cell dm; cell dm complete, vein M separating basal cells complete; R 2 + 3 short, ending in R 1 before junction with costal vein, sinuous; veins R 4 + 5 and M 2 fairly straight to wing margin; M 1 curved to wing margin; cell cup open slightly at wing margin; vein A 1 present, slightly sclerotized; anal lobe normal, not keellike in shape]. Abdomen. Brownish with yellow on posterior and lateral margins of each tergite; sternum yellow. Genitalia. Not dissected. Male. Unknown.” Type. Holotype female from: BANGLADESH: Harbang Forest, 6 mi. N. Chiringa, 50 ft., 18.ix. 1961, E.S. Ross & D.Q. Cavagnaro, deposited in CAS (# 13,910). Type examined during this study. When originally described, the wings of the type specimen were positioned in such a way as to obscure the salient characters of the venation. During this study, I rehumidified the specimen and carefully repositioned one of the wings so as to allow clear view of the venational characters necessary to verify its generic placement. Distribution. Known only from the type locality in Bangladesh.Published as part of Evenhuis, Neal L., 2003, World revision of the microbombyliid genus Mythenteles Hall & Evenhuis (Diptera: Mythicomyiidae), pp. 1-28 in Zootaxa 346 on pages 22-23, DOI: 10.5281/zenodo.15713

Reexamination of the unique type of Mythicomyia asiatica revealed characters that required it be transferred to Mythenteles, which was done by Evenhuis (2002 b). The wing venation, which was somewhat obscured when originally described, has been examined in a more clear view during this study and reveals a distinct vein M separating cells br and bm plus a distinct vein A 1 reaching the wing margin. The genitalia have not been dissected due to the only specimen known being the holotype. The external characters should serve to easily separate it from the congeners. Very little can be added to the original description and it is reproduced here with additions and modifications in square brackets []. DESCRIPTION. Female. Length: 1.23 mm. Head. [Eyes dichoptic]; “front and face yellowish white, [clypeus] black; vertex and occiput black, pubescence white, sparse; proboscis dark brown, extending well beyond oral margin, [apical portion] broken [off]; antennal segment I globosecylindrical, dark brown, with black hairs at apex; remainder of antennal segments missing. Thorax. Mesonotum and pleura black; scutellum, postalar callus, and stripe from humeral callus to wing base yellow; pubescence white; halter [stem and knob] yellow. Legs: yellow; coxae, bases of femora and apical tarsal segments brown; mid tibia straight, not distorted; pulvilli well developed, as long as claws. Wing. [(Fig. 13)] Hyaline, veins brown; [costa ends slightly beyond end of vein R 4 + 5;] four posterior cells; [Sc incomplete;] rm crossvein at basal 1 / 4 of discal cell; discal cell complete, [vein M separating basal cells complete]; R 2 + 3 short, ending in R 1 before junction with costal vein [, sinuous; Rs evanescent at junction with R 1; veins R 4 + 5 and M 2 fairly straight to wing margin; M 1 curved to wing margin; anal cell [open slightly at wing margin; vein A 1 present, weakly sclerotized]; [anal] lobe [reduced]. Abdomen. Yellow with black tergal pattern [as follows: basal 1 / 2 of tergite I, all of tergites V and VI, admedian basal hemispheres on tergites II–IV with basal band becoming thicker on each succeeding segment]; sterna yellow. Genitalia. Not dissected.” Male. Unknown. Type. Holotype female from: CHINA: Szechuan Province: MoTauKai, WanHsien, 4200–4400 ft., 26.ix. 1948, Gressitt & Djou; deposited in CAS (# 13909). The unique type was reexamined during this study. The wings of the type specimen were originally positioned in such a way as to obscure the critical characters of the venation. I have rehumidified the specimen and carefully repositioned one of the wings so as to allow clear view of the venational characters necessary to verify its generic placement. Distribution.

This species is easily separated from the congeners by the sinuous wing vein A 1 (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 R 4 + 5 and M 1; vein Sc incomplete, ending slightly less than halfway between origin of Rs and end of vein R 2 + 3; Rs evanescent at connection with R 1; R 4 + 5 slightly curved toward wing margin; vein M 1 curved toward wing margin; M 2 fairly straight to wing margin; vein dmcu closing cell dm absent; CuA 1 thick; vein A 1 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. . Mythenteles male genitalia..
