A new species of Idona DeLong (Hemiptera: Cicadellidae: Typhlocybinae) from Mexico, with an annotated list of species Author Pinedo-Escatel, J. A. Author Blanco-Rodríguez, E. text Zootaxa 2016 4114 3 320 330 journal article 39007 10.11646/zootaxa.4114.3.7 a3fc7bb2-eab7-4914-93f8-ffa9b74ccc53 1175-5326 265584 1283FAF7-70F3-4962-A060-844A8E2C701B Idona dmitrievi Pinedo-Escatel & Blanco-Rodríguez , sp. nov. ( Figs. 1−12 , 18−19 ) Description. Male head, face, legs, and abdomen white. Pronotum, scutellum, and wings with black spots and bands ( Fig. 18 ). Head in dorsal view narrower than pronotum, crown much longer medially than next to eye; eyes as wide as or wider than distance between eyes ( Figs. 11−12 ). Pronotum short, weakly projected anteriorly, marked with black dots at base or without marks. Mesonotum large, with pair of black maculae anteriorly ( Figs. 11−12 ). Each forewing with five black spots in basal half, distal portion infused with black ( Fig. 9 ). Female as in male ( Fig. 19 ), but dorsal spots smaller. Male genitalia. Abdominal apodemes well developed, large, broad at apex, extended to segment V ( Fig. 3 ). Pygofer conical, longer than wide ( Figs. 1 and 4 ); with dorsal preapical appendage slender, arising on distal ¾ of dorsal margin and extended posteromesad ( Fig. 2 ). Apex of pygofer lobe with large black decurved hook extended along apical margin, with median ventral lobe ( Fig. 1 ). Plates broad at base, and moderately tapered toward rounded tip, with lateral row of widely separated setae ( Fig. 7 ). Connective U −shaped ( Fig. 5 ). Style long, basal part thin, middle attached to connective with short lobes, preapical lobe rectangular with single seta, apex angled mesad, then posterad ( Fig. 5 ). Aedeagus robust, preatrium short, shaft compressed, with paired slender sinuate processes as long as shaft, arising near base, not extended beyond apex; shorter, wider, single process, placed ventrally at middle of aedeagus, curved dorsad ( Fig. 6 ). Female genitalia. Pygofer with long setae, sharply excavated at apex showing apical zone of gonoplacs ( Fig. 4 ), and sternite VII straight −oblique ( Fig. 8 ). Material examined type .

Male 2.4−2.6 mm ; female 2.6−2.7 mm ; head width between eyes 0.25mm ; vertex length 0.22mm ; forewing length 2.8 mm ; hindwing length 2.2 mm ; pronotum width 0.55 mm ; eye width 0.10 mm . Phenology. Specimens were collected in October, November, December, and January. Highest abundance was in December (Quezada-Daniel, pers. comm. ). Etymology. This new species is named in honor of Dmitry Alexandrovich Dmitriev in recognition of his importance as a taxonomist on typhlocybines. Distribution. Morelos, Mexico ( Fig. 17 ). Host. Avocado ( Persea americana ). Remarks. This species is similar to I. minuenda (see fig. 59 in Young 1952 ), I. biforma (see fig. 2 in Ruppel & DeLong 1952 ), and I. gigantica (see fig. 3 in Ruppel & DeLong 1952 ) in the structure of the aedeagus, but differs in having an additional process between the basal pair of aedeagal processes and the apex of the shaft ( Fig. 6 ). It also differs in the structure of the pygofer processes ( Figs. 1−2 ).
