Heteroberdeniella guadarramica sp. nov.

Figures 25–27

Diagnose. A Berdeniella -like species but with two large tenacula of unequal size arranged in line on epandrial appendages; thorax and wings without characteristics; gonostyli longer than gonocoxites and markedly thinner in distal half; lateral sclerites of aedeagus with sharp tips, inner sclerites broad with apical edge serrate.

Material: 1♂, holotype, Spain, Sierra de Guadarrama , 6–8000 ft., Aug(ust) 1927, B. Uvarov; small label: Brit. Mus. 1928–95. (deposited in the British Museum of Natural History, BMNH).

Description: Eye-bridge with of four facet rows, two rows near the middle on either side are of five facets; distance between the eyes equivalent to four facet diameters. Antenna typical of Pericomaini with short scape, globular pedicel and 14 flagellomeres; flagellomere barrel-shaped. Relative length of scape, pedicel and flagellomeres: 28–26–18–17–15–16–15–16–15–16–15–15–15–12–13–18, apical flagellomere with prolongation. Absolute length: 0.074–0.068–0.047–0.045–0.039–0.042–0.039–0.042–0.039–0.042–0.039–0.039–0.039–0.032–0.034– 0.047 mm. Flagellomeres 4, 5 and 6 with a pair of short digitate ascoids. Palpus with terminal segment missing; relative length of segments 1–3: 30–47–50–; absolute length: 0.079–0.124–0.132– mm.

Wing length 2.33 mm, width 0.89 mm; 2.63 times longer than the greatest width.

Abdomen with epandrium rectangular with round corners. a pair of opening near the basal edge. Epandrial appendages curved with 2 large tenacula in line, anterior one longer than the apical. Hypandrium narrow, widened at medially. Gonocoxites 1.2 times longer than wide, gonostyli slightly bent 1.8 times longer than the gonocoxites. Ventral parameral connection between gonocoxites with converging edges, apical edge curved. Aedeagus basally with dorsoventrally flattened ejaculatory apodeme, aedeagus straight, apical edge serrated. Between the dorsal bridge of the gonocoxites and the aedeagus a V-shaped (appears ring-shaped) sclerite (furca). Lateral blade-shaped sclerites run parallel, tip acute; their bases articulated with shorter sclerites whose ends are curved towards the furca.

Etymology: The species is named after the Sierra de Guadarrama, the type locality.

Comment: As in H. jaramensis the ejaculatory apodeme of the new species is dorsoventrally flattened, and between the ejaculatory apodeme and the gonocoxal bridge is a V-shaped sclerite (furca); as well as the ascoids were detected only on flagellomeres 4, 5 and 6. The type localities of H. jaramensis (Wagner, 1983) and H. guadarramica sp. nov. are close to one another but the terminalia clearly differ.
