Inermestoloides birai   sp. nov.

( Figs. 8–11 View FIGURES 5 – 9. 5 – 7 View FIGURES 10 – 15. 10 – 11 )

Inermestoloides   sp.; Martins & Galileo, 1998: 264.

Description. Male (Ƌ). Integument dark-brown; antennomere III reddish-brown on basal half, dark-brown on distal half; antennomere IV light reddish-brown on base, gradually darker toward apex (central area reddish-brown, distal third dark-brown); antennomere V reddish-brown on basal quarter, dark-brown on remaining surface; antennomeres VI, VIII and X yellowish on basal 2 / 3, dark-brown on distal third; antennomere VII reddish-brown on narrow basal area, dark-brown on remaining surface; antennomere IX dark-brown; antennomere XI dark-brown with small distal area reddish-brown; tibiae dark reddish-brown about middle; tarsi reddish-brown.

Head. Frons rectangular, finely, moderately abundantly punctate; with ochraceous pubescence, not obscuring integument, slightly denser laterally. Vertex with sculpture and pubescence as on frons. Antennal tubercles with sculpture distinctly finer, denser than on frons; with ochraceous pubescence, not obscuring integument. Area behind eyes finely punctate, pubescent close to eye, smooth, glabrous close to prothoracic margin. Ventral side of head shiny, glabrous, except for submentum with very short, ochraceous pubescence interspersed with some long, erect setae. Distance between lower eye lobes 0.25 times length of scape; distance between lower eye lobes in frontal view 0.90 times length of scape. Antennae 1.7 times elytral length, reaching elytral apex about middle of antennomere IX; antennomeres with thick, dark, erect setae ventrally, sparser, placed more apically toward distal antennomeres; antennal formula (ratio) based on antennomere III: scape = 1.16; pedicel = 0.50; IV = 1.39; V = 1.05; VI = 1.00; VII = 0.83; VIII = 0.83; IX = 0.72; X = 0.67; XI = 0.67.

Thorax. Prothorax subcylindrical, wider than long (1.1 times); sides slightly rounded, unarmed. Pronotum coarsely, densely punctate; with ochraceous pubescence, distinctly not obscuring integument. Sides of prothorax and prosternum with sculpture and pubescence as on pronotum. Prosternum and prosternal process with sculpture as on pronotum; with ochraceous pubescence (more yellowish-white depending on angle of light). Mesosternum and mesosternal prosternum process finely, abundantly punctate (punctures slightly finer than on prosternum); with pubescence as on prosternum. Mesepimera and mesepisterna with sculpture and pubescence as on pronotum. Metepisterna finely punctate; with ochraceous pubescence not obscuring integument. Metasternum coarsely, abundantly punctate; with ochraceous pubescence not obscuring integument (more yellowish-white depending on angle of light). Scutellum with reddish-brown pubescence, not obscuring integument. Elytra. Coarsely, deeply, abundantly punctate (punctures slightly sparser toward apex); pubescence reddish-brown (more yellowish depending on angle of light), not obscuring integument, slightly denser on some areas (apparent white pubescence on some areas ( Figs. 8–9 View FIGURES 5 – 9. 5 – 7 ) are just light reflection); apex rounded. Legs. Femora with short, decumbent, ochraceous setae, not obscuring integument.

Abdomen. Ventrites finely, moderately abundantly punctate (punctures distinctly denser on basal half of ventrite I); with ochraceous pubescence, distinctly not obscuring integument; apex of ventrite V truncate.

Dimensions (mm), holotype. Total length, 3.40; prothoracic length, 0.70; anterior prothoracic width, 0.80; basal prothoracic width, 0.75; humeral width, 1.10; elytral length, 2.45.

Type material. Holotype male (Ƌ) from BRAZIL, Amazonas [no detailed place; “ 1208, L.C. E IM”], 09.VIII. 1985, Bert Klein col. ( MZSP).

Etymology. The new species is named after the late Ubirajara Ribeiro Martins de Souza, for his enormous contribution to the knowledge of Cerambycidae   .

Remarks. Inermestoloides birai   sp. nov. can be separated from the other species of the genus by the features pointed in the key to species.

According to Martins & Galileo (1998) regarding Inermestoloides praeapicealba   (translated): “We examined a single specimen from Amazonas, with little accurate data: “Bert Klein, 09-Agosto-85, 1208, L.C. Eim” ( MZSP) that belongs to the genus and, probably, to a new species that we refrain to describe until the holotype of I. praeapicealba   can be studied.” Comparing photographs of the holotype of I. praeapicealba   with the specimen commented on by Martins & Galileo (1998), we agree that they belong to different species. Both have some features in common, as for example, the scape with a single color. However, I. birai   is more slender than I. praeapicealba   , and has the elytra 3.0 times longer than the prothorax (2.5 times in I. praeapicealba   ).
