Diagnosis: Forewing with a marginal pigmented band from R₄₊₅ to Cu1a, with a convex hyaline fenestrae on outer border between each vein end; hypandrium of one sclerite, with stout, spinose, blunt ended postero-lateral projections curved inwards, and a short, median posterior process, distally rounded, weakly sclerotized; phallosome with a small anterior mesal sclerite and four pairs of endophallic sclerites ( Fig. 19 ); ninth sternum elliptic, anteriorly with a deep cleft in the middle, sides converging towards a membranous posterior border.

Redescription of the male

Color: Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 15 ). Scape brown, pedicel yellow, f1 with pre-apical region brown and apex white, f2-f3 anteriorly brown, posteriorly yellow, with pre-apical region brown and apex white, f4-f5 brown with apex white. Femora yellow with two alternating brown bands, tibiae and tarsomeres 1-3 yellow. Forewing ( Fig. 16 ), with one brown spot on apex of areola postica, distal border of cu1 brown and, pterostigma with brown bands anteriorly and posteriorly; veins brown, with brown spots at wing margin ( Fig. 16 ). Hindwing with proximal third pale brown, a pale brown band from R₄₊₅ to vein M, veins brown ( Fig. 17 ) Morphology: Compound eyes without interommatidial setae ( Fig. 15 ). Forewing pterostigma long, slender, wider in the middle, narrowing posteriorly; areola postica with apex rounded, slanted posteriorly, M stem concave proximally, then almost straight, M1 almost straight, M2 and M3 sinuous ( Fig. 16 ). Hindwing R₂₊₃ and R₄₊₅ straight, M sinuous ( Fig. 17 ). Hypandrium ( Fig. 18 ) almost straight anteriorly, with setae as illustrated ( Fig. 18 ). Phallosome ( Fig. 19 ) with side struts long, slender, fused basally, V-shaped, fused posteriorly to external parameres, the latter stout and slightly curved inwards, bearing pores distally. Endophallic sclerites as in Fig. 19 . Epiproct wide based, almost straight anteriorly, with sides converging to straight posterior border; three mesal macrosetae, other setae as illustrated ( Fig. 20 ). Paraprocts broad, sensory fields with 33 trichobothria on basal rosettes, setae as illustrated ( Fig. 20 ).

Description of the female

Color: Essentially as in the male.

Morphology: Compound eyes without interommatidial setae (Fig. 21). Fore- and hind- wings (Figs. 22, 23) same as in the male. Subgenital plate broad, wide basally, with sides converging towards a straight posterior border, pigmented area wide, V-shaped, setae as illustrated (Fig. 24). Ninth sternum (Fig. 25). Gonapophyses: v1 long, curved, slender, acuminate, heavily sclerotized; v₂₊₃ stout, with pointed proximal heel, with eleven setae on v2 as illustrated, distal process slender, short, acuminate (Fig. 25). Epiproct triangular, with three mesal setae, other setae as illustrated (Fig. 26). Paraprocts almost triangular, broad, sensory fields with 27 trichobothria on basal rosettes; setae as illustrated (Fig. 26).

Measurements (in microns): FW:4120,HW:2950,F:1310, T: 2026, t1: 870, t2: 85, t3: 170, f1: 520, f2: 400, f3: 370, f4: 302, f5: 277, Mx4: 270, IO: 370, D: 480, d: 317, PO: 0.67.

Type material (Not examined): Holotype: ♂ (E.L. Mockford Collection,School of Biological Sciences, Illinois State University, Normal, Illinois, USA). Guatemala. Tikal. Departamento de Petén. 14.II.1956. ligth trap. I.J. Cantrall.

Material examined: México. Veracruz. Los Tuxtlas. UNAM Biology Station. 21.XII.1983. On Ficus trunks. 1 ♂. 09.VII.1988. On butressed tree trunks. 1 ♀. Ca. Laguna Escondida, ca. Estación de Biología, UNAM. 08.VII.1988. On butressed tree trunks. 1 ♀. All specimens collected by A.N. García Aldrete, and deposited in the National Insect Collection (CNIN), Instituto de Biología, UNAM, México City.

Comments: Mockford (1957) illustrated the hypandrium of T. spinosa connected to the phallosome, which may have hampered a detailed description of the latter (see figs. 3, 12 in Mockford 1957). The hypandrium of one sclerite in T. spinosa is shared by other thirteen species of Triplocania ( T. calcarata New , T. newi Silva-Neto, Rafael & García Aldrete , T. caudata New , T. caudatoides García Aldrete , T. cervantesi García Aldrete , T. halffterorum García Aldrete , T. immaculata New , T. chocoensis González, Carrejo & García Aldrete , T. embera González, Carrejo & García Aldrete , T. garciamarquezi González, Carrejo & García Aldrete , T. huitota González, Carrejo & García Aldrete , T. lithophila González, Carrejo & García Aldrete and T. lamensuraensis González, Carrejo & García Aldrete ). Triplocania spinosa differs from all other species with hypandrium of one sclerite by the structure of the hypandrium, phallosome, ninth sternum and pattern of forewing pigmentation and venation.
