Revision of the Mexican and Central American species of Mortoniella (Trichoptera: Glossosomatidae: Protoptilinae) Blahnik, Roger J. Holzenthal, Ralph W. Zootaxa 2008 2008-02-22 1711 1 1 72 Blahnik & Holzenthal, 2008 Blahnik & Holzenthal 2008 [151,426,1426,1452] Insecta Glossosomatidae Mortoniella Animalia Trichoptera 45 46 Arthropoda species propinqua sp. nov.   Fig. 23   Mortoniella propinquais most similar to  M. florica, resembling that species in having a very short inferior appendage, without protruding apicolateral projections, a phallicata with upright, rounded to subtruncate dorsolateral processes, and paramere appendages with scabrous apices. It is readily distinguished by the different development of tergum X, which has very elongate lateral lobes and a mesal projection that is either very weakly developed or absent. Adult. Length of forewing: male 3.1–4.0 mm, female 3.8–4.0 mm. Forewing with forks I, II, and III, hind wing with forks II and III. Overall color dark brown, palps darker brown, apices of tibiae, tarsal and basal antennal segments light brown. Wing bar at anastamosis indistinctly marked with pale, light brown setae. Ventral process of abdominal segment VI (male) short, ventrally oriented, subtriangular, subacute apically, not 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 without or with very weakly developed mesal projection and projecting lateral lobes, lateral lobes elongate, dorsoventrally flattened, slightly mesally curved, distinctly sclerotized, apex subacute. Inferior appendage very short, without apicomesal or apicolateral projections; basolaterally, with short, subacute projection on each side; mesal pockets of inferior appendage with apical processes short, dorsally curved. Paramere appendages moderately elongate, narrow, nearly uniform in width, dorsally curved from base, scabrous apically, apices acute. Dorsal phallic spine slightly enlarged basoventrally, contour weakly sinuous in lateral view, apex slightly dor- sally inflected; as viewed dorsally, with apex acute. Phallicata relatively short, dorsally with prominent, paired, dorsally protuberant, projections on either side, each more or less rounded and laterally explanate; lateral margin of phallicata slightly projecting. Endophallic membrane with single prominent, stout, curved spine.     Holotypemale: COSTA RICA: San José: Parque Nacional Braulio Carrillo, Quebrada Sanguijuela, 10°09'36"N, 083°57'47"W,  800 m,  27.iii.1987, Holzenthal, Hamilton& Heyn( UMSP000001384) (pinned) ( UMSP).    Paratypes: COSTA RICA: Alajuela: Río Peje& falls, ca.  1 kmSE San Vicente, 10°16'37"N, 084°23'17"W,  1450 m,  14–15.ii.1992, Holzenthal, Muñoz& Kjer— 1 male, 3 females(pinned), 5 males, 3 females(alcohol) ( UMSP), 2 males, 1 female(alcohol) ( NMNH). Etymology.
