Genus Hintelmannomyia JASCHHOF gen. n.

Type species: Hintelmannomyia aestimata JASCHHOF sp. n., described below.

Diagnosis:

Based on male adults, females and immatures are not known. The new genus differs from other Pteridomyiini by male genitalic characters. The gonocoxites are fused ventrally over their entire length, leaving only a vestigial emargination on the apical margin ( Fig. 9C ). The gonostyli bear a flat apical spine that is unusually large and bilobed ( Fig. 9C ).

Description:

Male. Body size:>1.0 mm. Head: Postfrons asetose. 3 ocelli. Occiput densely covered with scales intermingled with large setae. 1 row of postocular bristles. Eye bridge complete. Antennal scape and pedicel subequal in size, both with scales and setae. 12 flagellomeres, nodes with crenulate whorls of sensory hairs and hair-shaped translucent sensilla on apical half ( Fig. 9B ). Clypeus large. Maxillary palpus 4-segmented, first segment bulbous, with hair-shaped translucent sensilla,

second to fourth segments elongate-subcylindrical, gradually increasing in length, with scales and setae including some short, stiff setae.

Thorax:

As typical of Micromyidi ( JASCHHOF & JASCHHOF 2009 : fig. 14B). Scutum and scutellum with scales and setae, otherwise asetose. Wing: As typical of Micromyidi ( JASCHHOF & JASCHHOF 2009 : fig. 15F). Dorsal setae on basR1, apicR1, Rs, r-m, and CuA-stem, no ventral setae. Membrane somewhat smoky, with dense microtrichia and setae on both sides. Pattern of sensory buds: apicR1, 3; Rs, 1; r-m, 1 (dislocated to R 5 in one of the wings); R5 medially/distally, 2. Halter club-shaped, stem shorter than node, both densely covered with scales. Legs: Densely clothed in scales and setae. Pretarsal claws subrectangular, distal arm longer than proximal arm, toothed. Empodia reduced.

Preabdomen: Pleura of segments 1-8 with scales. Both tergum 1 and sternum 1 asetose, membranous. Terga and sterna of segments 2-8 at least partly sclerotized, with scales and setae. Tergal plaques 0/2/2/2/1/1/0/0. Terminalia: Fig. 9A , C-D. Tg9 short, with indistinct basal margin. Gonocoxites broadly fused ventrally, emargination on ventroapical margin vestigial. AntGA developed. Gonostylus with flat, unusually large, bilobed apical spine. Ejaculatory apodeme present, ducts of accessory glands well visible. Tegmen largely membranous. Cerci present as pair of short ovate lobes attached to tg9. St10 absent.
