INTRODUCTION

The families Cerambycidae and Disteniidae, together with Oxypeltidae and Vesperidae comprise the informal clade called Cerambycoidea, which with Megalopodidae, Orsodacnidae and Chrysomelidae represent the Chrysomeloidea superfamily (Švácha & Lawrence, 2014). Currently, the family Cerambycidae comprises eight subfamilies and about 38,000 species and the family Disteniidae four tribes and about 400 species (Švácha & Lawrence, 2014; Tavakilian & Chevillotte, 2018).

The genus Novantinoe, allocated in the family Disteniidae, was proposed by Thomson (1864) under the name Antinoe, and subsequently synonymized by Lacordaire (1869) with Distenia Lepeletier & Audinet-Serville, 1828. Santos-Silva & Hovore (2007a) revalidated the genus to accommodate species previously assigned in Distenia and because the name AntinoeThomson, 1864 was preoccupied by Antinoe Kinberg, 1856 (Annelidae, Polychaeta, Polynoidae, Harmothoinae) the authors proposed the nomen novum Novantinoe.Santos-Silva & Hovore (2007b) revised the entire genus, and Santos-Silva & Martins (2010) revised the South American species. Currently, the genus encompasses 37 described species, distributed from southern Mexico to southern South America, of which there are five with geographical distribution recorded from Mexico (Monné, 2018; Tavakilian & Chevillotte, 2018).

Into the family Cerambycidae, Eurysthea was described by Thomson (1860) and, recently, it was revised by Botero & Santos-Silva (2017). Currently, this genus is composed of 23 species distributed mainly in South America, with only one of them occurring also in Central America, E. cribripennis Bates, 1885. From Mexico there is not any species of Eurysthea reported; in Colombia there are currently six reported species (Monné, 2018; Tavakilian & Chevillotte, 2018).

MATERIAL AND METHODS

Photographs were taken with a Canon EOS Rebel T3i DSLR camera, Canon MP-E 65 mm f/2.8 1-5X macro lens, controlled by Zerene Stacker AutoMontage software. Measurements were taken in “mm” using measuring ocular Hensoldt/Wetzlar - Mess 10 in the Leica MZ6 stereomicroscope, also used in the study of the specimens. The references and geographical distribution were consulted at Monné (2018), and Tavakilian & Chevillotte (2018) catalogs. The acronyms used in the text are as follows:

Type Material: Holotype male from MEXICO, Oaxaca: Concepción Pápalo (2,275 m), 10.VII.1997, G. Nogueira col. (CNIN).

Remarks: Novantinoe oaxaquena sp. nov. is similar to N. cristinae Santos-Silva & Hovore, 2007; N. hefferni Santos-Silva & Hovore, 2007; and N. payettei Santos-Silva & Le Tirant, 2016 by its general appearance, the elytra bicolourus, and the inner and outer apical projections of metafemora subequal in length and with the same shape. It differs from N. cristinae by the body slender (wider in males of N. cristinae), head + prothorax slightly shorter than three times elytral length (slightly longer than twice elytral length in males of N. cristinae), pronotal and elytral pubescence more abundant (sparser in N. cristinae), elytral apex narrowly rounded (obliquely truncate in males of N. cristinae), and profemora without short spines ventrally (present in males of N. cristinae). The new species differs from N. hefferni by the head + prothorax slightly shorter than three times elytral length (2.5 times in N. hefferni), elytra slightly narrowed toward apex (distinctly narrowed toward apex in N. hefferni), elytral apex narrowly rounded (nearly acute in males of N. hefferni). Novantinoe oaxaquena sp. nov. differs from males of N. payettei by the slender body (wider in N. payettei), scape slender (distinctly widened in N. payettei), and elytral apex narrowly rounded (with distinct spine at outer angle in N. payettei). The general appearance of the new species also resembles N. noguerai Santos-Silva & Le Tirant, 2016, but differs from it by the maxillary palpomere IV not distinct securiform (securiform in males of N. noguerai), scape slender (wider in N. noguerai), and elytral apex narrowly rounded (spiniform in N. noguerai). For comparisons, photographs of the holotypes of N. cristinae, N. payettei, N. noguerai, and N. hefferni are available in Bezark (2018).

Etymology: The epithet, oaxaquena, is a demonym alluding to the inhabitants of Oaxaca state, in Mexico, the locality where the specimen was collected.

Dimensions (mm): Total length, 17.40; prothoracic length, 2.35; posterior prothoracic width, 2.10; anterior prothoracic width, 2.10; maximum prothoracic width (between apices of lateral tubercles), 3.00; humeral width, 3.45; elytral length, 12.20.

Type Material: Holotype male from MEXICO, Oaxaca: Sierra de Juarez (850 m), 15.V.1998, G. Nogueira col. (CNIN).

Remarks: The general appearance of Novantinoe fabiolae sp. nov. (female) is as that of N. hefferni (male). However, the scape (Fig. 5) is abruptly widened toward apex and is not rugose. In N. hefferni, the scape (see in Bezark, 2018) is more gradually widened toward apex and is distinctly rugose. As we never saw this kind of sexual dimorphism in the other species of Neotropical Disteniinae, we believe that they belong to different species. Novantinoe fabiolae differs from N. cristinae by the denser pubescence on pronotum and elytra (sparse in both sexes of N. cristinae); from N. payettei by the pronotal and elytral pubescence denser, and upper eye lobes narrower (pubescence sparse and upper eye lobes wider in N. payettei); from N. noguerai by the elytral punctures sparser and upper eye lobes narrower (punctures more abundant and upper eye lobes wider in N. noguerai); and from N. oaxaquena sp. nov. by the scape wider and not rugose (slender and rugose in N. oaxaquena), and by the posterior third of the elytra more uniformly narrowed toward apex (somewhat rounded narrowed in N. oaxaquena).

Etymology: This species is named after Fabiola Lopez C., the wife of Guillermo Nogueira collector of the holotype. This is in deep appreciation for her years of support of his work in entomology.

Etymology: Named in honor of Guillermo Nogueira, collector of the holotype.

Remarks: Eurysthea nogueirai sp. nov. resembles some specimens from E. hirca (Berg) 1889 without yellowish maculae on elytra (variable characteristic in that species) but differs by the shape of pronotum; the anterior gibbosities slightly elevated (more elevated in E. hirca); the elytra with sparse and uniform setae throughout (denser and forming patches of pubescence in E. hirca); and the elytral apex with only external spine (bispinose in E. hirca). By the absence of yellowish maculae on elytra, the new species also resembles E. sordida (Erichson, 1847), but differs from it by the elytral pubescence sparser (notably denser in E. sordida); and the elytral apex with spine at outer angle (elytral apex unarmed in E. sordida). Eurysthea nogueirai sp. nov. also differs from E. cribripennis (Bates, 1885) by the antennomeres III-VII with distinct spine at inner apex (in E. cribripennis the spine is present just in antennomeres III-IV); by the elytra without yellowish maculae on elytra and with short decumbent setae interspersed with elongated erect sparse setae (with yellowish maculae and with decumbent setae in E. cribripennis); and by the elytral apex obliquely truncated (straightly truncated in E. cribripennis). Eurysthea nogueirai sp. nov. is the first species of the genus registered from Mexico.

Metanepisternum with short, decumbent, abundant golden setae (almost indistinct depending on angle of light) on anterior and lateral margins, glabrous on central region; interspersed with long, erect, white setae (more erect, abundant basally). Metaventrite finely punctate, sparser and finer toward median region and posterior margin; with short, decumbent, sparser golden setae; with some long, sub-erect, yellowish-white setae throughout.

Elytra: Moderately coarsely, abundantly punctate, sparser toward apex, on apex smooth; with short decumbent, thick, white setae throughout, interspersed with elongated erect sparse setae; apex obliquely truncate, with elongated spine at outer angle, sutural angle unarmed.

Legs: Apices of meso- and metafemora rounded.

Abdomen: Ventrites smooth; with short decumbent, thick, white setae laterally, central region glabrous, interspersed with some elongated erected setae. Apex of ventrite V curved.

Dimensions in mm (male): Total length, 10.3; prothorax length, 1.9; anterior width, 1.6; posterior width, 1.5; largest prothoracic width, 1.7; humeral width, 1.7; elytral length, 6.9.

Type Material: Holotype male from Colombia, Valle del Cauca: Municipio de la Cumbre (Vereda Chicoral, 03°34’26”N, 76°34’56”W), 22-26.III.2017, Sinyaev col. (MZSP).

Etymology: The new species is in honor of Nakagome Masaji (Japan), a renowned collector of insects. He is a personal friend of Anton Olegovich Kozlov (Russia), who sent and donated the holotype for MZSP collection, and requested the name as a special favor, to expresses his thankfulness and respect to him.

Remarks: By its general appearance, Eurysthea nakagomei is similar to E. cribripennis (Bates, 1885), but differs by the prothorax unarmed laterally (with antemedian tubercle and lateral spine in E. cribripennis), scutellum nearly glabrous (covered with dense yellowish pubescence in E. cribripennis), and body with sparse moderately long white setae (in E. cribripennis the body is covered with denser and longer yellowish setae). Among the species of Eurysthea with the prothorax unarmed (E. barsevskisiBotero & Santos-Silva, 2017; E. nearnsiBotero & Santos-Silva, 2017; E. parva Martins & Galileo, 2013; E. rotundicollis (Martins, 1995)), the new species differs from all of them by the prothorax with sparse and fine pubescence (denser and obscuring the integument in these species), and the scutellum nearly glabrous (densely covered with yellowish pubescence in these species). The new species differs from E. barsevskisiBotero & Santos-Silva, 2017; E. nearnsiBotero & Santos-Silva, 2017; and E. rotundicollis (Martins, 1995) by the yellow anterior and posterior maculae being interrupted (continuous in those species).
