Two new species of Novantinoe (Disteniini, Disteniidae), two new species of Eurysthea (Elaphidiini, Cerambycinae, Cerambycidae), and new geographical records

Two new species of Novantinoe from Mexico, N.  oaxaquena and N.  fabiolae; and two new species of Eurysthea, E. nogueirai, from Mexico, and E. nakagomei from Colombia are described. Furthermore, geographical distributions of three species are expanded. Key-Words. Cerambycoidea; Colombia; Mexico; Taxonomy.

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:

Novantinoe oaxaquena Botero, Heffern & Santos-Silva, new species (Figs. 1-4)
Description: Male: Integument mostly brownish, slightly darker on some areas; mouthparts, apex of antennal tubercles, yellowish-brown; scape dark reddish-brown; pedicel yellowish-brown basally; antennomeres III-X reddish-brown on basal ¾ (more yellowish-brown depending on intensity of light), gradually darkened on distal quarter, especially on III-VII; prosternal process gradually reddish-brown toward apex; elytra reddish-brown on anterior third, gradually yellowish-brown toward apex, except dark brown triangular area on anterior sixth around scutellum, oblique dark brown band dorsally, from about apex of anterior quarter to before middle (together V-shaped), slightly distinct, irregular brown macula dorsally after middle, and dark brown punctures on anterior ¾; femora reddish-brown, slightly darkened toward apex; tibiae with basal dark reddish-brown ring, reddish-brown (more yellowish-brown depending on intensity of light) on wide central area, and slightly, gradually darkened toward apex; tarsi reddish-brown except blackish apex of claws. Pubescence somewhat golden; erect setae pale yellow. Thorax: Prothorax 1.45 times wider than long (including lateral tubercles); lateral tubercles large, conical, placed at middle; anterior margin slightly narrower than posterior one. Pronotum with five distinct tubercles: one on each side of anterior half, nearly conical, higher than the others; one on each side of posterior half; another centrally, subelliptical, slightly sulcate longitudinally. Pronotal pubescence abundant, not obscuring integument, except on glabrous central tubercle and top of lateral tubercles of disc; anterior and posterior constrictions well-marked; central area, among tubercles, minutely, abundantly punctate (sparsely on central gibbosity); remaining surface nearly smooth. Sides of prothorax with abundant pubescence, partially obscuring integument, between anterior and posterior constrictions, sparsely pubescent on remaining surface. Prosternum sparsely pubescent close to procoxal cavities and laterally, with very sparse setae on remaining surface. Mesoventrite with pubescence distinctly exposing integument, glabrous laterally. Mesanepisternum and mesepimeron with pubescence denser than on mesoventrite. Metanepisternum and metaventrite with abundant pubescence not obscuring integument, except central, triangular area of metaventrite with pubescence distinctly sparser. Scutellum with pubescence obscuring integument.
Abdomen: Ventrites with abundant pubescence, not obscuring integument, except on glabrous posterior area of I-IV, and nearly glabrous basal area of V; ventrite I slightly shorter than ventrite II; apex of ventrite V truncate. 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).

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

Novantinoe fabiolae Botero, Heffern & Santos-Silva, new species (Figs. 5-8)
Description: Female: Head dark brown dorsally, gradually brown toward prothorax; apex of antennal tubercles light reddish-brown; ventral side brown (slightly reddish depending on angle of light), gradually light reddish-brown toward prothorax; postclypeus reddish-brown except dark brown area close to frons; labrum reddish-brown (yellowish-brown depending on intensity of light); palpi reddish-brown; antennae reddish-brown, with dark brown ring on apex of some antennomeres; pronotum dark brown on wide central area, gradually reddish-brown toward anterior and posterior margins; prosternum reddish-brown anteriorly, gradually brown toward prosternal process and dark brown toward sides of posterior half; ventral surface of mesothorax brown centrally (more dark reddish-brown depending on intensity of light), dark brown laterally; metanepisternum and sides of metaventrite dark brown, and remaining surface of metaventrite reddish-brown; elytra reddish-brown except dark brown band along suture (anteriorly involving scutellum), and dark brown band along epipleura (both bands fused at apex); femora reddish-brown; tibiae yellowish-brown, gradually light reddish-brown toward apex; tarsi light reddish-brown; abdominal ventrites I-IV dark brown except slightly reddish central posterior half, and transverse yellowish-brown distal area; abdominal ventrite V dark brown on basal half, gradually dark reddish-brown toward apex. Pubescence yellowish-white, more golden on antennae, tibiae and tarsi.
Head: Frons narrow vertical; pubescence forming narrow transverse band on each side of center close to postclypeus, nearly absent on remaining surface. Antennal tubercles elevated, close each other, separated by shallow sulcus, with apex rounded, more distinctly elevated; with moderately sparse pubescence except glabrous apex. Vertex finely, moderately sparsely punctate between antennal tubercles and posterior margin of upper eye lobes, slightly coarser, denser toward prothorax; pubescence moderately sparse between antennal tubercles and middle of area between upper eye lobes and prothorax, then gradually shorter and sparser, absent close to prothoracic margin.

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). Thorax: Prothorax slightly wider than long, sides with small, spiniform tubercle before middle (apex truncated); coarsely, densely punctate except subsmooth, transverse band at anterior and posterior margin and on gibbosities; with short, abundant, golden setae (not obscuring integument), interspersed with elongated erect setae. Pronotum with five gibbosities, slightly elevated: two sub-circular, placed at each side just after middle; two sub-circular, placed on each side of posterior quarter; and one elongated, from midlength to posterior quarter. Pronotal surface coarsely, moderately sparsely punctate between gibbosities; area outside of region delimited by gibbosities coarsely, densely punctate; with short, golden setae (not obscuring integument), slightly denser between gibbosities, with long, erect, sparse, yellow-ish-white setae, mainly between gibbosities. Prosternum, transversely striate (subsmooth on some areas) on anterior third; with some sparse elongated erect yellowish setae, mainly on anterior third. Prosternal process at narrowest point, equal to 0.4 times the procoxal cavity width. Mesoventrite, mesepimeron and mesanepisternum with short, decumbent, sparse golden setae (slightly distinct depending on angle of light) interspersed with moderately short, sub-erect yellowish-white setae. Mesoventral process emarginate at apex, equal to 0.7 times the mesocoxal cavity. Metanepisternum with short, decumbent, abundant golden setae (almost indistinct depending on angle of light) interspersed with long, sub-erect, yellowish-white setae (more erect basally). Metaventrite coarsely 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.

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 near-ly 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. barsevskisi Botero & Santos-Silva, 2017;E. nearnsi Botero & 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. barsevskisi Botero & Santos-Silva, 2017;E. nearnsi Botero & Santos-Silva, 2017;and E. rotundicollis (Martins, 1995) by the yellow anterior and posterior maculae being interrupted (continuous in those species).
