Fig. 15 This species is distinctive and diagnosed by several characters considered together. Its most unusual character is the form of the dorsal phallic spine, which is enlarged basally and conforms with a correspondingly curved basal part of the phallotheca. Other useful characters for diagnosing this species include the form of the inferior appendage, which is divided mesally and has the lateral apices narrowed and distinctly downcurved, the sclerotized dorsolateral spines at the base of the endophallic membrane, and the subtruncate lateral lobes of tergum X. Mortoniella elongata(Flint)also has the apices of the inferior appendage strongly curved downward, but this species has paired, rounded dorsal processes on the phallicata (not evident on the original illustration) and also has a prominent curved endophallic spine. FIGURE 14. Mortoniella mexicana, new species. Male genitalia: A—lateral; B—segment IX and tergum X, dorsal; C— phallic ensemble, ventral. FIGURE 15. Mortoniella munozi, new species. Male genitalia: A—lateral; B—segment IX and tergum X, dorsal; C— phallic ensemble, ventral; D—dorsal phallic spine, dorsal. Adult. Length of forewing: male 3.5–3.7 mm. Forewing with forks I, II, and III, hind wing with forks II and III. Overall color medium brown, palps and basal part of antennal and tarsal segments darker brown, apices of tibiae, tarsal and basal antennal segments light brown. Wing bar at anastamosis distinct, marked by pale, light brown setae. Ventral process of abdominal segment VI (male) short, ventrally oriented, subtriangular, subacute apically, length slightly greater than width at base, slightly constricted basally. Male genitalia. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin forming rounded projection in dorsal half, narrowing ventrally; segment deeply mesally excised dorsally and ventrally, dorsal excision narrow, much less than half width of segment. Tergum X with short, acute mesal projection and projecting lateral lobes, lateral lobes with apices angularly truncate, distinctly sclerotized and dorsoventrally flattened, slightly mesally curved. Inferior appendage with very short, acute apicomesal projection; basolaterally, with elongate, narrow, posteriorly directed projections on each side, projections acute apically, strongly ventrally and mesally reflexed; mesal pockets of inferior appendage with apical processes short, dorsally curved. Paramere appendages elongate, narrow, nearly uniform in width, emerging from membranous lateral lobes, dorsally curved from base, base slightly flattened, apex acute, textured with elongate, adpressed, scale-like spines in apical half. Dorsal phallic spine with distinct bulge ventrally, conforming to dorsal margin of phallicata, dorsal margin sinuous, apex distinctly dorsally curved; as viewed dorsally, with apex acute. Phallicata tubular, dorsal margin distinctly concave; with acute, paired, scabrous processes emerging from posterodorsal margin, their bases less sclerotized. Endophallic membrane short, simple, without spines.
