The presence of eight species of Cerambycidae from the Cusco Valley is reported. The valley of

Cusco corresponds to the area where the city of Cusco is located. It has several micro-basins with

diverse vegetation that contain a high diversity of flora and fauna. The identified species are:

Parandra barclayi Santos-Silva 2015, Cotyclitus potiuna (Galileo and Martins, 2007), Megacyllene

punensis Martins & Galileo, 2008, Megacyllene sp., Eurysthea sordida (Erichson, 1847),

Deretrachys montanus (Tipmann, 1953), Eriocharis devestivus Monné & Martins 1973 y

Alcathousites asperipennis (Fairmaire et Germain, 1864). An identification key is included for the

species studied.

INTRODUCTION

attractive for collectors (Monné et al., 2017)

plants are found. Many important features have been cited about cerambicids, so: reproduction,

taxonomy and ecological role (Monné et al., 2017)

Morphologically, the Cerambycidae family is characterized by antennae that are usually filiform,

elongated and with 11 segments, rarely serrated and with 12 segments or more, generally they are

inserted into pronounced tubercles; eyes usually emarginate; prothorax without pleural sutures;

tibias with two different tibial spines; tarsi usually pseudotetramerous with the fourth segment

and, within Cerambycidae, five of the nine Cerambycidae subfamilies: Cerambycinae, Lamiinae,

Lepturinae, Parandrinae and Prioninae with a total of 846 species and 403 genera in 57 tribes

(Monné & Chaboo, 2015; Monné et al., 2012). There are few data for this family at Cusco, several

species have been reported in three subfamilies and 45 genera (Carrasco, 1978; Escalante, 1974)

The objective of this work is to make known the Cerambycidae species collected in the Cusco

Valley and to elaborate an identification key for them.

The Cusco Valley or Huatanay Valley

The Cusco Valley corresponds to the sub-basin of the Huatanay river, the city of Cusco is located in

altitude is between 3300 and 3400 m, with a dry climate, little rainfall in winter, with an average

(Cusi-Bravo, 2012).

The studied species correspond to samples deposited in the Laboratorio de Entomología de la

Universidad Nacional de San Antonio Abad del Cusco (CEUC-UNSAAC). Identifications were

made using specialized keys (Aragão & Monné, 2011; Botero & Santos-Silva, 2017; Di Iorio, 1995;

Ferrú & Elgueta, 2011; Galileo & Martins, 2007; Monné et al., 2017; Nearns & Swift, 2011;

Santos-Silva, 2015) as well as consultations with specialists, the same that are recognized in the

respective section.

Parandra Latreille, 1802

Type locality: Peru, Cuzco, Purmamarca (3550 m, 2 hours N from Ollantaytambo). Distribution:

Peru (Monné, 2018) Parandra (Parandra) barclayi Santos-Silva, 2015.

Diagnosis: antennae shorter than the body; pronotum laterally marginated; apex of the elytra

rounded; maxillary palps pointed; tarsus pentamerous; upper lobe of eye present; disc of pronotum

pronotum without keels; reddish brown throughout the body, without setae.

Parandra collected in Limatambo, at 2600 masl (10.1.1966) and Andahuaylas at 3300 masl

(29.IV.1974) “… of medium size (2.5 cm), it has a blackhead and a blackprothorax , and the rest of

the body is brown … ”(Carrasco, 1978, p. 75). This description establishes a notable difference with

P. barclayi, which has a reddish-brown body.
