Geitogonalia tetracorni  sp. nov.

( Figs 22–35View FIGURES 22–30View FIGURES 31–35)

Diagnosis. Aedeagus ( Figs 29, 30View FIGURES 22–30) shaft short and stout, slightly narrower apically, apex dorsally with pair of strong horn-shaped processes directed anterodorsally, ventrally with pair of horn-shaped processes directed anteroventrally. Female abdominal sternite VII ( Fig. 31View FIGURES 31–35) posterior margin concave on each side of dentiform projection.

Measurements (in mm; 2 ♂, 2 ♀). Length of body ♂ 6.3–6.7, ♀ 6.7–7.1.

Male. Coloration. Anterior dorsum (crown, pronotum, and mesonotum) yellow ( Figs 22, 23View FIGURES 22–30). Crown with black transverse stripe posteriorly, strongly broadening on each side of midline between ocellus and eye; sometimes with medial black spot anteriorly. Pronotum with black transverse stripe at posterior margin. Mesonotum with small black spot laterally on mesoscutum anterior margin. Forewing ( Figs 22, 23View FIGURES 22–30) orange in its basal fourth; corium and clavus greenish; apex black; veins yellow, but R faded. Face ( Fig. 24View FIGURES 22–30) yellow; gena black posteriorly to eye only; clypeus slightly lighter along its lateral and ventral margins; rostrum black. Thorax lateral and ventral portions yellow. Legs yellowish-orange, protibia brown basally, almost black towards apex, mesofemur black. Abdomen black.

Structure. Head ( Figs 22–24View FIGURES 22–30) moderately produced anteriorly, median length of crown approximately 6/10 of interocular width and 4/10 of transocular width; each ocellus slightly closer to midline of crown than to adjacent anterior eye angle. Other features as in G. piei  sp. nov.

Male genitalia. Pygofer ( Fig. 25View FIGURES 22–30), in lateral view, well produced posteriorly; posterior margin broadly rounded; without processes; macrosetae distributed on posterior third of disk and extending anteriorly along ventral and dorsal margins; thin setae present ventrally on medial third. Valve ( Fig. 26View FIGURES 22–30), in ventral view, with lateral margins rounded, constricted medially. Subgenital plate ( Fig. 26View FIGURES 22–30), in ventral view, triangular, not fused to its counterpart basally, outer lateral margin slightly sinuous, narrowing gradually towards apex, with uniseriate row of macrosetae intercalated with thin setae; in lateral view, not extending posteriorly as far as pygofer apex. Connective ( Fig. 27View FIGURES 22–30), in dorsal view, T-shaped, stalk long and narrow, distinctly longer than arms, keeled dorsally, transition from arms to stalk gradual. Style ( Fig. 27View FIGURES 22–30), in dorsal view, with apophysis elongate, distinctly longer than apodeme, not extending as far posteriorly as connective; with lobe on outer median portion bearing single elongate seta, apex narrow, obliquely truncate. Paraphyses ( Fig. 28View FIGURES 22–30) present but very small, consisting of well sclerotized basal transverse plate and pair of weakly sclerotized rami with sclerotized apices, curved inwards and upwards. Aedeagus ( Figs 29, 30View FIGURES 22–30) symmetrical; without preatrial process; dorsal apodeme longer and narrower than shaft, apex slightly curved anterolaterally; shaft short and stout, slightly narrower apically, apex dorsally with pair of strong horn-shaped processes directed anterodorsally, about 1/4 as long as shaft, ventrally with pair of horn-shaped processes directed ventrally and outwards, shorter than dorsal processes.

Female. Coloration. As in male, except larger black spot extending to base of frons, visible from dorsal and anterior view.

Structure. As in male.

Female genitalia. Abdominal sternite VII ( Figs 31, 32View FIGURES 31–35), in ventral view, slightly longer than wide, posterior margin concave on each side of dentiform projection. “Internal” sternite VIII, in dorsal view, without distinct sclerotized areas. Pygofer ( Fig. 32View FIGURES 31–35), in lateral view, strongly produced posteriorly, posterior margin narrowly rounded, macrosetae located mostly on posterior portion and extending anteriorly along ventral margin. First valvifer ( Fig. 33View FIGURES 31–35) about as long as wide. First valvula ( Fig. 33View FIGURES 31–35) slightly curved dorsally, with apex acute; dorsal sculptured area strigate, extending from basal portion of blade to apex; ventral sculptured area scale-like, restricted to apical portion of blade; ventral interlocking device restricted to basal half of blade, located along ventral margin with distal portion directed dorsally. Second valvula ( Fig. 34View FIGURES 31–35) moderately expanded beyond basal curvature; dorsal margin moderately convex; ventral margin with slight preapical prominence; apex subacute; blade with about 27 subtriangular continuous teeth; denticles distributed on teeth and on dorsal and ventral apical portions of blade; ducts extending to apical portion of blade and to teeth or terminating below them (about five basal-most teeth do not receive ducts). Gonoplac ( Fig. 35View FIGURES 31–35) with basal half narrow and apical half distinctly expanded; apex obtuse; blade with many tiny spiniform processes on apical portion and extending anteriorly along ventral margin.

Etymology. The specific epithet refers to the four horn-shaped apical processes of the aedeagus ( Figs 29, 30View FIGURES 22–30).

Remarks. As mentioned above, this new species and G. buccina  sp. nov. are very similar in coloration, but the aedeagus of the former has two pairs of apical processes, one dorsally and another ventrally ( Figs 29, 30View FIGURES 22–30).
