Nariscus spinosus (Burmeister, 1835) an African squash bug new for Gran
Canaria island, Spain (Heteroptera: Alydidae)
INTRODUCTION
During a research on the
Mediterranean Alydidae of the Iberian
peninsula and North Africa, we found
some images posted on Groups and
Internet blogs that had an uncertain or
incorrect identification. Therefore the
first author (PD) tried, where possible, to
identify exactly the name of the species
in question.
INTRODUCCIÓN
Durante una investigación sobre los
Alydidae mediterráneos de la península
ibérica y Norte de África, encontramos
algunas imágenes publicadas en Grupos
y blogs de Internet que tenían una
identificación incierta o incorrecta. Por
lo tanto, el primer autor (PD) intentó,
cuando fue posible, identificar
exactamente la especie en cuestión.

In fact, the concept according to which
it is possible to report in scientific
publications the name of True Bugs
species easily identifiable by external
characters reproduced in the photographs,
is now well established (Goula et al.,
2012). Therefore, the so-called “Citizen
Science”, tends to contribute to the
knowledge of the distribution of some
species of the mentioned areas, with the
relative host plants.
In the photographic blog of the second
author (IK), dedicated to insects of Gran
Canaria (
https://pbase.com/coridon/ gran_
canaria_insects
), a species with a
predominantly African and Middle Eastern
distribution emerged: it is illustrated
below.
MATERIAL AND METHODS
Nariscus spinosus (Burmeister, 1835)
New records:
Gran Canaria: Street GC
505, along the Barranco de Arguineguin,
El Sao env., 5 km North from the coastal
traffic circle, 27.I.2017, 1 ex. male, under
Acacia farnesiana (L.) Willd
, photo by
Ivan Kruys.
The species was identified with figures
and keys, according to the Revision of
African Alydinae (Göllner-Scheiding,
2000) and the comparison with specimens
present in the first author’s collection
(P.D.). Nariscus spinosus is easily
distinguishable for having an elongated
triangular head with much longer sides
than the base, protruding clypeus pointed
in shape, posterior femurs of the male with
a clear band before the apex and a long
spine in the same position, ventrally; the
first article of the posterior tarsi is almost
twice as long as the 2nd and 3rd joined
(Figs. 1- 2).
De hecho, el concepto según el cual es
posible notificar en publicaciones
científicas el nombre de especies de
chinches, fácilmente identificables en
fotografías mediante caracteres externos,
está bien establecido (Goula et al., 2012).
Por tanto, la denominada “Ciencia
Ciudadana”, tiende a contribuir al
conocimiento de la distribución de
muchas especies, así como sus plantas
hospedadoras.
En el blog fotográfico del segundo
autor (IK), dedicado a los insectos de
Gran Canaria (
https://pbase.com/coridon/
gran_ canaria_insects),
apareció una
especie con una distribución
predominantemente africana y del Medio
Oriente: se ilustra a continuación.
MATERIAL Y TODOS
Nariscus spinosus (Burmeister, 1835)
Nueva cita:
Gran Canaria, carretera
GC505, a lo largo del barranco de
Arguineguín, El Sao, alrededor de 5 km al
norte de la carretera costera, 27.I.2017, 1
ex. macho, bajo Acacia farnesiana (L.)
Willd, foto de Ivan Kruys.
La especie fue identificada mediante
las claves y figuras de la Die Alydinae
Afrikas (Göllner-Scheiding, 2000) y la
comparación con especímenes presentes
en la colección del primer autor (P.D.).
Nariscus spinosus se distingue fácilmente
por tener una cabeza alargada, triangular
y de lados mucho más largos que la base,
clípeo de forma puntiaguda, fémures
posteriores del macho con una banda clara
antes del ápice y una espina larga en la
misma posición, ventralmente; el primer
artículo del tarso posterior es casi el doble
de largo que el segundo y el tercero unidos
(Figs. 1-2).

DISCUSSION
The species is distributed in some
areas of Middle Orient, Northern and
Eastern Africa: Algeria, Egypt. Cyprus,
Iran, Iraq, Oman, Saudi Arabia, Yemen.
In Tropical Africa: Sudan (Göllner-
Scheiding, 2000; Aukema et al., 2013).
The recent record of Gran Canaria is the
first for all the Islands and the
westernmost of its Areal. According with
Naranjo Cigala et al., (2009) Acacia
farnesiana (Fig. 3), native to South
America, is known in the Canary Islands
as “aromero”; it is considered an invasive
species in many tropical and subtropical
parts of the world.
DISCUSIÓN
La especie se distribuye en algunas
zonas de Oriente Medio, Norte y Este de
África: Argelia, Egipto. Chipre, Irán,
Irak, Omán, Arabia Saudita, Yemen. En
África tropical: Sudán (Göllner-
Scheiding, 2000; Aukema et al., 2013).
El reciente récord de Gran Canaria es el
primero de todas las islas y el más
occidental de su área. De acuerdo con
Naranjo Cigala et al., (2009) Acacia
farnesiana (Fig. 3), oriunda de
Sudamérica, es conocida en las islas
Canarias como aromero y es
considerada como especie invasora en
muchas partes tropicales y subtropicales
del mundo.

As a cultivated species it is
documented as far back as the 18th
Century, but it was considered as
naturalized only in the 20th Century. The
plant belongs to the Leguminosae and
releases seeds which are sucked by N.
spinosus as documented for many
Alydidae species (Linnavuori, 1987;
Vivas & Burgers, 2015; Dioli et al.,
2021). The area of the Barranco de
Arguineguin (Fig. 4) is one of the most
invaded by A. farnesiana in whole Gran
Canaria (Naranjo Cigala et al., 2009).

Como especie cultivada está
documentada desde el siglo XVIII, pero
sólo se consideró naturalizada hasta el
siglo XX. La planta pertenece a las
Leguminosae y libera semillas que son
succionadas por N. spinosus como se ha
documentado para otras muchas
especies de Alydidae (Linnavuori, 1987;
Vivas & Burgers, 2015; Dioli et al.,
2021). La zona del barranco de
Arguineguin (Fig. 4) es una de las más
invadidas por A. farnesiana en toda Gran
Canaria (Naranjo Cigala et al., 2009).

... sordidatus (Stål, 1858). They were revised by GÖLLNER-SCHEIDING (2000) and two of them arrived in Europe and are considered alien species: N. inornatus, recently found in Spain (Alicante), the first and only European record so far (DIOLI et al., 2021), and N. sordidatus, known from several southern European countries: Italy (Sicily only), Portugal, and Spain, as compiled by GROSSO-SILVA & RAMOS (2021). Since then, N. sordidatus was also recorded from Greece (Crete) and Cyprus (DAVRANOGLOU et al., 2021). ...
... As stated in that note, the species was not new for the Portuguese fauna as its occurrence was already reflected (without any additional details) in the sixth volume of the Catalogue of the Heteroptera of the Palaearctic Region (AUKEMA et al., 2013). More recently, a second Portuguese locality was briefly mentioned by DIOLI et al. (2021) when N. inornatus was recorded from Spain. ...
... So far, it has been reported from Algeria, Cyprus, Egypt, Iran, Iraq, Oman, Saudi Arabia, Yemen and tropical Africa (AUKEMA, 2022). Recently, the first record of N. spinosus for the Canary Islands was published: A single male was found in the Barranco de Arguineguín (Gran Canaria) in January 2017 (DIOLI et al., 2021). Now, the presence of N. spinosus on the island of Fuerteventura can be reported: On 24-08-2021, a nymph ( Fig. 1) and several adult specimens were found and photographed by Óscar Sampedro Moreira beside the road FV-2 near Oasis Wildlife Park in La Lajita, located at the southern coast of the island. ...
... Within the last two decades, various updated checklists of the Heteroptera of the Canary Islands were published (AUKEMA et al., 2006(AUKEMA et al., , 2013ROCA-CUSACHS et al., 2020). Since then, several new records for the archipelago or at least for specific islands have been reported (RIEGER, 2020;BAENA & SANTOS, 2021;DIOLI et al., 2021;VAN DER HEYDEN, 2023). In this note, more new records are reported in addition to the above mentioned publications. ...
... Photos of the specimen were uploaded to the online database iNaturalist (see here). DIOLI et al. (2021) reported a record of Nariscus spinosus (Burmeister, 1835) (Heteroptera: Alydidae) from Gran Canaria, stating that it was the first one of this species for the Canary Islands. Furthermore, VAN DER HEYDEN (2022) reported a record of N. spinosus from Fuerteventura as the first one for that island. ...

The Acacia farnesiana shrub species is native to Central America, but naturalized and considered an invasive species in many tropical and subtropical parts of the world. This study examines some of the characteristics of an Acacia farnesiana allochthonous population in the Canary Islands. When an alien species colonizes a new environment, it interacts with new elements to which is not accustomed: predators, pollinators, dispensers, competitors. To become successful these new elements need to fill all the species requirements. This paper attempts to determine the degree of resilience of this species and how dangerous can be for the native community. The information provided by this study isof maximum importance when deciding how dangerous this invasive species is, as well as determining how it should behandled and, where advisable, eradicated
