2582 Author Chamorro, Maria Lourdes Author Holzenthal, Ralph W. text Zootaxa 2010 2010-08-31 2582 1 252 journal article 1175­5334 Polyplectropus yolandae Chamorro-Lacayo & Holzenthal Figs. 115 , 130 Polyplectropus yolandae Chamorro-Lacayo & Holzenthal, 2004: 213 . [ Type locality: Costa Rica , Guanacaste , Parque Nacional Guanacaste , Río Tempisquito , Maritza ; UMSP; male.] Polyplectropus yolandae is most similar to P. zuliae , new species in the overall shape of the preanal and inferior appendages and in the shape of the phallus. Polyplectropus yolandae can be distinguished from P. zuliae by the shape of the mesoventral process of the preanal appendage, being apically rounded in P. yolandae , by the narrower and more elongate intermediate appendage, and by the broader dorsal branch of the inferior appendage. FIGURE 115. Male genitalia of Polyplectropus yolandae Chamorro –Lacayo & Holzenthal, 2004 (holotype): A—left lateral view; B—dorsal view; C—caudal view; D—ventral view; E—phallus, lateral view. Adult. Length of forewing 4.8–5 mm , n = 25. Color of head, thorax, and legs yellowish-brown; setae on body grey and golden brown; tegulae with long, golden brown and grey setae; setae on wings golden brown along costal margin with patches of grey setae interspersed along margin and on most of wing surface. Male genitalia. Sternum IX in lateral view deltoid, anterior margin submedially produced, posterior margin entire; in ventral view rectangular, anterior margin concave, posterior margin with slight median flange. Tergum X membranous, oblong, bearing dorsal microsetae; lower lip of tergum X membranous, smooth, without dorsal microsetae; in caudal view produced dorsad of phallocrypt. Intermediate appendage not longer than inferior appendage, digitate, with long and short setae throughout; in dorsal view broad, tapering mesoventrally to subacute apex; in caudal view digitate, narrowing apically, directed posteromesad; median papillate lobe flanking phallocrypt laterally, bearing small apical setae. Preanal appendage tripartite; dorsolateral process elongate, originating from dorsum of mesolateral process, directed anterad, recurved posteromesad then posterolaterad, tapering mesally into acute apex; mesolateral process setose; in dorsal view oblong, in lateral view broadly convex; mesoventral process setose; in lateral view hook-like, directed ventrad, anteroventral margin concave, posterior margin convex; in caudal view processes slightly separated, ventral margin of process acute. Inferior appendage bipartite with anterior basal plate not extending anterad beyond sternum IX when observed in lateral view; dorsal branch setose, in lateral view pandurate (variable form from Nicaragua has broader dorsal branch and is larger overall), posteroventral margin produced medially; in ventral view narrow, lateral margin convex, entire, posterior margin subacute, mesal margin slightly undulate, subapically expanded, becoming concave, expanding posterad into ventral branch; ventral branch setose, elongate, bearing robust, sclerotized spines along entire dorsal surface; in lateral view digitate, narrowing posterad; in ventral view deltoid, mesal margin slightly angled, gradually converging mesally. Phallus short; dorsal phallic sclerite in lateral view sinuate, apex pandurate; apex of dorsal phallic sclerite in dorsal view rounded; dorsolateral arm of dorsal phallic sclerite in lateral view tapering subapically; in dorsal view tapering subapically; endothecal membrane without embedded spines. Female genitalia. Typical of species group. Material Examined.
