Vestiture composed of four upright setae into disk, one or two for each interstriae step 3

05-step one.08 (step one.06) times more than greater, widest on base, edges converging some so you’re able to prior next, alternatively narrowly round at the front end; coarse, subcontiguous, transverse asperities toward prior half of, basic line developing an enthusiastic unbroken costa near to prior margin; facial skin subreticulate, subshining, that have meagerly rough, deep punctures towards the posterior half of just, escort girls in Lowell MA separated because of the diameter away from a puncture; vestiture consisting of six vertical, much time setae, five together prior margin plus one inside for every single basal corner.

Elytra step 1.48-1.51 (step 1.50) moments longer than greater, 1.46-1.47 (1.46) more than pronotum; corners synchronous for the basal around three-fourths, generally game trailing; striae perhaps not amazed, punctures rather strong, spread because of the diameter of good puncture; interstriae nearly doubly wider since striae, shining, punctures several-third how big strial punctures, uniseriate; interstriae ten incredibly raised in order to sternum 6; declivity high, convex, strial and you will interstrial punctures slightly smaller than into disk, striae 1 weakly content.

Scolytodes triangulus letter

Protibiae with horizontal pearly whites step 1 and you will dos subequally size of, other lateral white teeth much faster. Metatibiae having five socketed horizontal white teeth into the distal third.

Symptomatic features: It is known on the closely related S. schwarzi (Hopkins) (look for fig. 142 p. 496 when you look at the Timber 1982) by the large proportions (1.8 mm vs step one.3-1.six mm), from the asperities being restricted to help you anterior 1 / 2 of, and by the feminine frons are punctured regarding the content town. sp. (Figs 11, twenty five, 27) Holotype females: COSTA RICA, Heredia state: La Selva biol. sta., Puerto Viejo, 50 yards, 5 March 1993 (H. A. Hespenheide), FOT 5/sixteen Carapa guianensis [INBio]. Allotype: exact same analysis because the holotype, FOT . Paratype: Costa Rica, Puntarenas: Osa Peninsula, 2.5 mi. SW Rincon, seven February 1988 (H. Hespenheide), air sweep, step 1 _ [INBio].

Etymology: of Latin tri, about three, and you may angulus, having a corner, referring to the newest triangular shaped tuft out of setae regarding ladies frons.

Frons a little happy out-of above top amount of sight to epistoma, horizontal margins out of satisfied city slightly raised, subparallel, a little diverging for the upper number of vision; skin from content town densely punctured in the median two-thirds, moment setae arising from most punctures; vestiture comprising an effective triangular tuft from enough time, fantastic, subplumose setae, broadly developing during the vertex, then slowly converging for the the tip from the quantity of antennal installation.

Antennal pub that have two highly, acuminately procurved surgical stitches noted from the rows of hairlike setae, terminal sector setose. Funiculus six segmented.

02-step one.04 (step one.03) times longer than greater, largest at the legs, edges weakly arcuate, converging some so you’re able to anterior fourth, next generally game at the front; anterior third declivuous, asperities as an alternative coarse, better asperities always basal 3rd; skin reticulate, painful, several low punctures expose towards the posterior 1 / 2 of except short, radiant granules present in median basal town; vestiture comprising five brief, erect setae together anterior margin.

Elytra 1.step 19-step 1.23 (1.21) minutes longer than broad, step 1.2step one-step 1.23 (1.22) more than pronotum; corners synchronous to the below basal one or two-thirds, instead narrowly game at the rear of; striae step one a bit, anybody else not amazed, punctures superficial, small, spread by 50 % of a diameter regarding an excellent puncture; interstriae 2 to 3 times large than striae, glowing, punctures hidden, two-third the dimensions of strial punctures, spaced because of the nearly twice the diameter, generally uniseriate; interstriae ten exceedingly raised almost to top; declivity modestly high, convex, most of the punctures hidden. Vestiture consisting of simple spatulate bristles on the strange-numbered interstriae, mostly toward declivity.

Protibiae with a powerful horizontal enamel step one stretching beyond tooth 2, most other lateral white teeth obscurely shown. Intercoxal procedure for prosternum 0.30-0.forty moments due to the fact greater as a good procoxa. Metatibiae having half a dozen socketed lateral teeth with the distal third.

Pronotum step one

Description men: (n=1) just like lady except frons convex, simply somewhat, transversely happy just a lot more than epistoma; frontal vestiture composed of sparse, second, hairlike setae next to epistoma.
