Three new species of caddisflies in the genus Smicridea McLachlan (Trichoptera: Hydropsychidae) from Omar Torrijos and Santa Fe National Parks Rázuri-Gonzales, Ernesto Armitage, Brian J.

Smicridea   Fig. 3.   Diagnosis.  Smicridea( S.) dividua sp. n.is most similar to  S.( S.) choltaFlint, 1974from Guatemalaand Nicaraguabased on the shape of tergum X and the phallic apparatus in ventral view. However,  Smicridea( S.) dividuais easily separated from  S.( S.) choltadue to the bilobed posteroventral process of the phallobase, which is broad and entire in  S.( S.) cholta, and the posterodorsal margin of the phallobase, which is produced into a slender lobe in the new species, but is undulate and bearing a few short spines on the lateral surface in  S.( S.) cholta .Furthermore, S. ( S.) dividuahas a single sinuous spine, which shape is unique in this group whereas  S.( S.) choltahas a pair of long slender spines.   Description. Adult male.Forewing length average 4.3 mm( n= 7). Body color light brown (specimen preserved in alcohol). Head and thorax light brown with brown setae, dorsally thorax with dark brown marks anterad. Antennae and legs yellowish brown, antennae with short brown setae, legs with long brown setae. Maxillary palps 5-segmented; maxillary palps with long brown setae and a few thick long setae anteroventrally on segment II. Forewing membrane light brown, with brown and dark brown setae, with whitish transversal band in the nygmal area membrane, mostly denuded. Wing venation typical for the subgenus. Abdominal segments VI and VIII glands oval, larger than containing segment.  Male genitalia.Segment IX in lateral view ( Fig. 3A) much longer dorsally than ventrally, anterolateral margin slightly concave, anterodorsal corner not produced, forming nearly straight angle; anterior portion of dorsal margin long, slightly concave, mesal portion of dorsal margin convex, bearing small microsetae, closer to tergum X than to anterolateral margin of segment IX, posterior portion membranous; ventrolateral margin oblique, sinuous; ventral margin short, truncate; in dorsal view ( Fig. 3B) anterior margin strongly concave, lateral margin sinuous, inflated mesally, mesally bearing microsetae. Tergum X in lateral view ( Fig. 3A) narrow, setose, much shorter than segment IX, apex truncate, posterodorsal corner produced dorsad; in dorsal view ( Fig. 3B) narrow, with rounded apices, separated by mesal notch, less than half its length, membranous mesally. Inferior appendage ( Figs. 3A-C) two-segmented; first segment not extending beyond posterior margin of tergum X, covered with setae, inflated apically; second segment digitate, approximately 1/2 as long as first segment, with short setae on margins, in dorsal view apex acute, slightly inflated on distal half. Phallic apparatus ( Figs. 3E-D) with phallobase enlarged, open ventrally; apical section open, dorsolateral corner of phallobase produced into a slender lobe; posterodorsal margin of phallobase mesally produced, acute; posteroventral margin produced into two slender digitate lobes, the ventral one with subacute apex, directed laterad and the dorsal one with bilobed apex, directed dorsolaterad, without spines or processes on lateral surface; in ventral view, posteroventral process deeply notched, notch basally rounded and undulate, each lobe slender, bilobed apically, directed laterad; endothecal membranes in lateral view with a long, sinuous, apically acute spine, in ventral view, bilobed, broad basally and slender apically, deeply notched mesally.  Female and immature stages.Unknown.   Distribution. Panama( Coclé Province).   Etymology.From the Latin word dividuus, referring to the unique divided endothecal spine.   Material examined.   HOLOTYPE MALE. PANAMA: Coclé: Omar Torrijos National Park, Quebrada La Yayas, 8.66168°N, 80.5952°W,  586 m,  22–26.iii.2017, E.
