Description

The holotype was previously studied, but is not available for a detailed description.

Male specimen ( Figs 3 View Figs 1–4 , 15 View Figs13–16 , 26 View Figs25–30 , 32 View Figs 31–36 , 40 View Figs 37–41. 37–38 , 42 View Figs 42–45 )

MEASUREMENTS. Body length 16.4 mm.

HEAD. Clypeal edge broadly arcuate, lacking teeth. Anteroventral clypeal tooth acute. Clypeal and genal surface rugose, clypeogenal suture ill-defined. Posterior genal angle obtuse. Frontal surface reduced, smooth. Dorsal ocular width greater than one-quarter interocular distance. Interocular surface smooth. Cephalic horn emerging centrally from clypeofrontal surface, parallel-sided with quadrate apex, curved throughout, apically flattened, 5.7 mm in length.

PROTHORAX. Carina along anterior pronotal edge broad medially, narrowing laterally. Anterolateral pronotal lobe smooth, sectioned posteriorly by abrupt shelf. Lateral pronotal carina and pronotal edge distinctly forking anteriorly then merging posteriorly, forming closed carinated ellipse. Pronotal surface smooth anteriorly, transitioning posterolaterally into chagrined texture. Centrally raised projection bifurcated with deeply excavated anteroventral surface defined by uneven texture. Propleuron and prosternum broadly setose; with long (~ 1 mm) dark setae. Anterior prosternal apex rounded.

ELYTRA. Glossy overall. Striae 1–6 widest anteriorly; narrowing posteriorly. Elytral stria eighth absent. Elytral striae nine absent on basal sixth. Interstriae convex, impunctate.

HINDWING ( Fig. 40 View Figs 37–41. 37–38 ). Membrane edge between AP and AA lobed. AP vein reduced.

VENTRITES. Meso-metasternal suture posteriorly arcuate. Surface of median metasternal lobe ( Fig. 42 View Figs 42–45 ) finely punctate and convex, with scarce setigerous punctation along mesocoxae. Lateral metasternal lobe densely setose. Visible abdominal ventrites 1–6 laterally setose. Pygidium finely punctate.

PROTHORACIC LEGS. Anterior and posterior surface of profemur with dense row of long dark setae. Ventral profemoral surface finely punctate, lacking setae. Protibia with four distinct teeth. Protibial forespur straight with apex tapering inward.

MESOTHORACIC LEGS. Posterior surface of mesotrochanter with dense tuft of long rufous setae. Anterior and posterior surface of mesofemur with dense row of long dark setae. Outer surface of mesotibia serrate. Width at mesotibial apex one-third mesotibial length.

METATHORACIC LEGS. Posterior surface of metatrochanter with tuft of long dark setae. Anterior and posterior surface of metafemur with dense row of long dark setae. Outer surface of metatibia serrate. Width at metatibial apex one-quarter metatibial length.

MALE GENITALIA. Aedeagus length: 3.6 mm. Medially and laterally paired sclerites of genital segment broad, ill-defined. Paramere ( Fig.26 View Figs25–30 ) laterally flattened, gently tapered; apex broad and slightly inclined with ventral tooth. FLP endophallite ( Fig. 32 View Figs 31–36 ) sigmoidal; broad distally, narrowing and inflecting centrally.

Female specimen ( Figs 4 View Figs 1–4 , 16 View Figs13–16 )

Similar to male with the following exceptions: body length 14.7 mm. Clypeal edge slightly sinuous medially. Clypeofrontal carina bi-tuberculate, with width equivalent to dorsal ocular width. Anterolateral pronotal lobe surface smooth, immediately transitioning to fused granulate texture posteriorly. Central pronotal ridge slightly overhanging, with lateral tubercles and shallow anterior excavation. Posterolateral and posterior pronotal surface chagrined.

Variation

Body length 15–20 mm. Clypeal teeth absent or round and indistinct. Cephalic horn acute in small males; less than 1 mm in length. Pronotal armament in small males limited to notched anterior ridge. Pronotal ridge lacking lateral tubercles in small females.

Distribution ( Fig. 65 View Fig )

High elevation (2625–3055 m) in the Ecuadorian and northern Peruvian Andes. The single record from “Amazon” is based on an historical specimen, the holotype of Pinotus simulator Luederwaldt with vague data (see Max Barclay pers. com., comment below).

Natural history

Specimens with data were collected in cloud forest using pitfall traps baited with fish and in bovine dung.

Remarks

In the original description of Pinotus simulator, Luederwaldt (1936) describes the type specimen as “seeming atrophied, perhaps belonging to [ P. buckleyi ]”. Luederwaldt goes on to describe the cephalic and pronotal armament of the specimen as “a small quadrate hump” in place of a long cephalic horn, and a “small sinuous carina” instead of a large bifurcating pronotal projection. We suspected Luederwaldt was referring to a poorly developed male representative of A. buckleyi . Upon examination of photographs of the specimen in question, we have confirmed this to be the case; the external morphology of P. simulator matches a typical small male of A. buckleyi in all respects, and the name is therefore considered a new junior synonym of A. buckleyi .
