Summary
DescriptionMegophthalmidia illyrica Chandler & al. 2006 ♂ adult sx side.jpg |
Megophthalmidia illyrica Chandler & al. 2006 ♂ (Diptera Sciaroidea Mycetophilidae Leiinae Megophthalmidiini). Megophthalmidia Dziedzicki 1889: 19 (IT: 3) spp. FLVOR of this species in IT outside IT-88. Same specimen, lateral-sx, dorsal and frontal habitus. Cfr. notes¹ over the above image. Megophthalmidia Dziedzicki 1889, Aphrastomyia Coher & Lane 1949 and Mohelia Matile 1978 compose a single clade well nested within Leiinae. 13 synapomorphies support Megophthalmidiini monophyly: 8 have independent origins within Leinae, 5 are uniquely derived in this tribus. No exclusive apomorphies lump Mohelia with Aphrastomyia, and the clade is supported by 4 apomorphies that also appear elsewhere. NOTES: 1. TBL 2.5 mm. Specific diagnostic characters: Sc short, incomplete, inclined toward R, ending free; R1 short, curved toward wing margin, longer than r-m. Few interocelar setae; no distinct longer seta at pedicel apex. |

Sc short, incomplete, inclined toward R, ending free; R1 short, curved toward wing margin, longer than r-m.
TBL 2.5 mm
♂: Head black, grey dusted. Ocelli arranged as in M. ionica. Antenna shorter than thorax, dark brown, sometimes a little lighter basally. Flagellomeres about as long as broad. Proboscis relatively shorter than in M. ionica, only about 1/3 of eye height. Palpus yellow. Thorax black, grey dusted, sometimes narrowly orange brown on humeral margin. Mesonotum with short uniformly distributed black bristling, appearing paler from some aspects and longer black setae laterally. Anterior spiracle yellow. Prothorax with black bristling and several strong upturned setæ on pronotal lobe. 4 strong scutellar marginal setae with short dark hairs between. Laterotergite with whitish to dark bristling. Wing yellowish. Vein R ends at 0.6 of wing L, subequal to a little longer than r-m. Costa extends 0.75 distance from R, to M, venation otherwise as in M. ionica. Haltere yellow. Wing L 2.3-2.8 mm. Legs yellow including coxae and hind femur. Mid tibia with 3 4 a, 3 d, 3 p near tip and 3 v setae. Hind tibia with 14 a, 16 irregular d on apical 0.75 and 4-6 p setae near tip. Abdomen shining dark brown to blackish, with black bristling. Tergites 1-4 more or less yellow on apical third to half, markings may be more or less interrupted in middle (especially on 3-4); tergite 5 may be obscurely yellow apically. Sternites vaguely yellowish. Genitalia dark brown. Tergite 9 with lateral processes near side margins and a prominent median process, which has an apical emargination. Gonocoxites medially emarginate, more enlarged ventrally than in M. ionica, so that sternites from 5 onwards are ventrally directed in situ; gonostylus with dorsal process bearing long pointed marginal processes so that it appears deeply bifid.
Few interocelar setae; no distinct longer seta at pedicel apex.
