Notalina (Neonotalina) ralphi sp. nov.

Diagnosis.
This new species can be easily recognized by the absence of processes on the median portion of tergum X, inferior appendages with ventromesal process indistinct laterally and distinct ventrally with subtruncated apex, and Y-shaped phallotremal sclerite in lateral view. Notalina ralphi sp. nov. is morphologically similar to N. franciscana based on the subtruncate mesoventral process of the inferior appendages in ventral view. However, N. ralphi sp. nov. has the acuminate preanal appendages, which in N. franciscana are clavate. In addition, in the new species the ventrolateral margin of the segment X has stout, short setae, whereas N. franciscana has these setae only in the apex of the tergum.
Description.
Male. Head brown (in alcohol) (Fig. 1B View Figure 1 ); maxillary and labial palps brown; antennae pale brown (Fig. 1A View Figure 1 ). Thorax brown; pleuron pale brown (Fig. 1C View Figure 1 ). Forewing brown, with small hyaline spot at thyridial cell; forewing length 7.8 mm (n = 4), forks I and V present (Fig. 1D View Figure 1 ); hind wing length 6 mm (n = 4), forks I, III, and V present, fork I very narrow and fork III with very short petiole (Fig. 1E View Figure 1 ). Legs pale brown; tibial spur formula 2, 2, 4 (Fig. 1A View Figure 1 ). Segment IX, in lateral view, broadest ventrolaterally, anterior margin slightly sinuous (Fig. 2A View Figure 2 ); apicodorsal area with paired, poorly developed, distantly situated protuberance; posterolateral margin bearing setae. Preanal appendages setose, long, and slender, ~ 2/3 length of segment X (Fig. 2A, B View Figure 2 ); in dorsal view, apex acuminated towards inner margin, bearing long setae (Fig. 2B View Figure 2 ). Segment X, in lateral view, saddle-shaped; anterodorsal area slightly convex; mid-dorsal area without lateral protuberance; distal area without dorsomesal and dorsolateral processes; apicolateral processes rounded, bearing short stout setae (Fig. 2A View Figure 2 ); in dorsal view, V-shaped apicomesal incision extending anteriorly ~ 1/3 length of segment X; with a row of 5-7 short stout setae subapically. Inferior appendage, in lateral view, with broad basal portion, apical portion elongate, digitate, setose; basodorsal process rounded, smaller than basoventral process; dorsomesal process long and broad, apex acute, directed apicodorsad (Fig. 2A View Figure 2 ); in ventral view, basoventral process well developed, slightly asymmetrical, rounded, apex directed mesad (Fig. 2C View Figure 2 ); ventromesal process, in lateral view, indistinct (Fig. 2A View Figure 2 ); in ventral view, distinct with subtruncated apex (Fig. 2C View Figure 2 ). Phallic apparatus with a pair of strongly sclerotized, acuminate phallobase flanges, apex directed dorsad (Fig. 2D View Figure 2 ); phallotremal sclerite well developed, roughly Y-shaped in lateral view (Fig. 2D View Figure 2 ), with an anteriorly directed projection when viewed ventrally (Fig. 2E View Figure 2 ).
