description: Cluzobra vockerothi, sp.n.
(Figs. 11, 29–30)
Diagnosis. Wing maculate only on distal fifth of the wing, a darker macula at base of Rs, and a transverse macula at level of apex of R1. Syngonocoxite with a deep distal mesal notch, with three strong spines at apex, a sclerotized projection ventrad to the insertion of the gonostyle, with three strong teeth; gonostyle spatular, curved, weakly sclerotized.

Description. Male. Head. Occiput light yellowish brown, darker at apex; mid ocellus absent, lateral ocelli closer to eye margin than ocellus diameter, ocellar area slightly darker; front and clypeus yellowish, setose; maxillary palpus brown, 1+4 palpomeres, setose, palpomeres increasing in length to apex; labella yellowish. Scape and pedicel rounded, yellowish, with scattered setae; flagellomeres yellowish, elongated, basal half brownish, setose. Thorax. Pronotum yellowish, with some longer and other smaller setae. Scutum light brown, anterior and posterior margins yellowish, with four lighter, yellowish longitudinal bands intertwined with brown bands, smaller setae scattered and some stronger acrostical and dorsocentral bristles; scutellum light brown, darker at posterior margin, six stronger scutellar bristles and some smaller setae. Pleural membrane yellowish. Proepisternum light yellowish brown, with some stronger setae. Anepisternum, katepisternum, and laterotergite light brown, mesepimeron light yellowish brown, laterotergite brownish, metepisternum whitish yellow, mediotergite brown, yellowish close to insertion of abdomen. Anepisternum and katepisternum bare, laterotergite setose, mediotergite with a mesal and a pair of more lateral tufts of setae with a mesal and a pair of more lateral tufts of setae. Halter yellowish, setose. Legs. Legs mostly yellowish, coxae brownish laterally and at distal half, and femora basally; tibial spurs 1:2:2, yellowish brown, front spur more than twice front tibial width at apex. Wing (Figure 11). Length, 2.4 mm. Wing mostly translucid, a continuous brownish macula around base of Rs, r–m, M1+2 and base of medial fork, and other maculae at apex of anal lobe, at distal eighth of wing and transversely at level of apex of R1. Membrane with macro and microtrichia; humeral cell bare of macrotricha; basal cell with some few macrotrichia near to apex. Sc complete, short, reaching C at basal fourth of wing; R1 long, reaching C at distal third of wing; R5 reaching C before apex of M1; C extending a third the distance between R5 and M1 r–m oblique, longer than base of Rs; M1+2 longer than r–m; medial fork complete; M4 entirely absent; A1 very short, scarcely visible. Abdomen. Tergites and sternites 1–7 yellowish. S8 U–shape, bare of setae, T8 wide and short, setose. Terminalia (Figures 29–30). Terminalia yellowish brown, setose. Syngonocoxites elongated, with a deep mesal notch reaching its basal third, distal projections with three to four spines, and an additional strongly sclerotized projection laterally, with three strong teeth, just ventrad to the insertion of the gonostyle. Gonostyle long, spatula–like, without setae or spines. Aedeagus elongated, with a distal expansion. T9 elongated, with setae but not spines, without large lateral projections on distal margin. Cercus simple.
Etymology. This species is named in honor of J.R Vockeroth, eminent Canadian dipterist, with an extensive contribution to the knowledge of the Mycetophilidae.
Comments. The maculation of the wing is quite distinctive, though similar to that of C. fascipennis Edwards. As well, C. fascipennis and C. fissisterna Matile have a deep notch mesally on the syngonocoxite, the gonocoxite at each side with a sclerotized projection just ventrad to the insertion of a long, spatula shaped gonostyle. In C. fascipennis, particularly, this projection is strongly sclerotized. In C. vockerothi, sp.n. these three features are present, and when added to the similarity in the shape of the wing suggests that this species belongs to the fascipennis – group. The shape of the gonocoxal projection with three strong teeth is a unique apomorphy, and clearly delimits a separate species.
