Mortoniella (Mortoniella) calovebora Blahnik and Armitage , new species

Fig. 2

Diagnosis. This is a rather typical, but distinctive, species of the “florica subgroup.” Mortoniella calovebora is easily distinguished from other described species of the subgroup by the length and asymmetry of the apicoventral lobes of the inferior appendages ( Fig. 2C ). The asymmetry of the ventral lobes of the inferior appendages seems to be a consistent feature of this species and is a unique character within the genus.

Description. Length of forewing: male 3.0– 3.3 mm; female 3.2–3.3 mm. Forewing with forks I, II, and III present, hind wing with forks II and III. Spur formula 0:4:4. Overall color (in alcohol) light brown, anastamosis unpigmented, but otherwise not evidently marked.

Male genitalia. Ventral process of segment VII laterally compressed, short, ventrally projecting, rounded apically, length slightly greater than width at base, process slightly retracted anterobasally. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin rounded dorsally, narrowing ventrally; segment deeply excised dorsally and ventrally, forming lateral lobes, separated dorsomesally by much less than ½ width of segment. Tergum X relatively elongate, lateral margins subparallel, apically with short, subtriangular mesal projection; apicolateral lobes elongate, compressed, subacute, slightly mesally curved; ventrolateral lobes nearly obsolete; ventromesal lobes not evident. Inferior appendages without dorsolateral lobes, but with apicoventral lobes elongate, upturned, and asymmetrically developed, that of the right side narrower apically and more distinctly out-turned, both lobes acute apically. Mesal pockets of inferior appendage with apical processes short and weakly curved. Paramere appendage elongate, narrow, extending about same length as dorsal phallic spine, slightly widened preapically, widened apex with narrow, adpressed, scale-like spines. Dorsal phallic spine, as viewed laterally, undulate in contour, spine distinctly widened on ventral margin at about middle, ventral bulge articulating with dorsal margin of phallicata, apex acute, weakly upturned; in dorsal view ( Fig. 2D ), lightly widened in middle and preapically, apex acute. Phallicata moderately elongate, dorsal margin with broadly rounded, paired, dorsolateral projections, lateral margin with slightly produced, rounded and compressed projection. Endophallic membrane simple, with single prominent curved ventromesal spine; phallotremal spines absent.

Female and immatures. Unknown.

Etymology. This new species is named for the Río Calovebora from which it was first collected. The name is formulated as a noun in apposition.
