Abstract

This paper describes three new species of Ateuchus for Mesoamerica. The new taxa are: A. gershensoni (copulatory hooks subequal in size and spinelike), A. perezvelai (small size; frons very convex; one very big copulatory hook and two small spine-like ones associated with a spiny fascies) and A. perpusillus (anterior pronotal margin incomplete; small and compact copulatory hooks, associated with a spiny fascies) from southern Mexico, Guatemala and Honduras. Redescriptions are also given for A. chrysopyge (Bates) (big size; copulatory hooks, one big, a spine-like medium-sized one and a hook-like small one) and A. guatemalensis (Bates) (pronotum punctured; anterior pronotal margin almost effaced; pygidium convex; copulatory hooks, two small and compact and one very thin and curved). New country and distributional records are also registered for Mexico, Guatemala, Belize, Honduras and El Salvador. Distribution map, internal sac of aedeagus illustrations and photographs of dorsal habitus are included, as well as drawings of the dorsal habitus of the three new species. The present work clarifies the situation of the genus in Mesoamerica and updates knowledge of the group in Mexico.

  ]]> This work is an extension of the work originally done on North American Ateuchus (Kohlmann 1984). It describes three new species from the Mesoamerican area. The new taxa are: A. gershensoni, A. perezvelai and A. perpusillus. It also reports new country and distribution records for Mexico, Guatemala, Belize, Honduras and El Salvador.

This paper attempts also to partially update the knowledge of the North American Ateuchus fauna (Kohlmann 1984), by reporting the presence of four more species in Mexico (two new species, A. gershensoni and A. perezvelai; and two new country records, A. chrysopyge (Bates) and A: guatemalensis (Bates)) and thus increasing the number of previously known species from this country from eight to twelve. The paper also enlarges the distribution of previously recorded species in Mexico.

A redescription of A. chrysopyge and A. guatemalensis is also given. Since their original description by Bates (1887) no one had reported any information regarding any of the two species. Together with previous information from Costa Rica (Kohlmann 1996-97) and Panama (Howden and Young 1981), this paper is filling a knowledge gap of the Mesoamerican area, although Nicaragua still remains largely unknown.

Mesoamerican Ateuchus species closely resemble each other and many times it is very difficult to separate them solely on the ground of external morphology. Natural variation compounds this problem further. Without the aid of the analysis of the internal sac of the aedeagus, identification of many species would rest on shaky ground. It is therefore that the internal sacs of all species have to be studied and depicted, as is the case here with these previously unknown taxa and the redescribed ones.
 

Materials and Methods

Specimens came from my personal collection, as well as from the H.F. Howden, Ottawa, Canada; M.A. Morón and C. Deloya, Instituto de Ecología, Xalapa, México and R. Cave, Escuela Agrícola Panamericana, El Zamorano, Honduras.
 
 
]]>

The specimens were studied using a stereozoom binocular microscope. Measurements were made to the nearest 0.1 mm using an ocular micrometer. Genital dissections and preparations were done following the techniques described by Zunino (1978).

Types and paratypes of the new species are deposited at the Canadian Museum of Nature, Ottawa.

The internal sac of the aedeagus has three copulatory hooks (Fig. 2), one big and two smaller ones. The apical lamellae are also three (Fig. 2).

Allotype: Female. Length 5.5 mm, greatest width 3.5 mm.

These were female specimens which are always difficult to identify and which can be easily confused with the females of A. klugi. The following specimens cited as klugi in Kohlmann (1984) belong to this new species: El Suspiro and Lacanjá-Chansayab, Chiapas and Temax, Yucatán.

Remarks. Howden and Young (1981) cited an A. (near?) guatemalensis in their work on Panamanian Scarabaeinae. Those specimens actually represented a new species, which was later described under the name of A. howdeni (Kohlmann 1996-1997).
 

This species was only known from the typical locality in Chiapas, its distribution has now been greatly expanded with the knowledge of its presence in the Mexican state of Campeche and in neighbouring Belize. The records are as follows: ]]>  

Mexico: Campeche: Chicanna, 10 km W Xpujil, 12-14/VII/1983, 300 m, trop. seas. For. car. tps. S. & J. Peck, (1); Escárcega, 6 km W El Tormento, 23/VII/1983, evergreen trop. forest, fungi & litter Ber., S. & J. Peck, (2).

Belize: Orange Walk: Lamanai, 22-26/II/1980, palm forest trail, Glen Kit, (1).
 

This is the second known locality for this species in the state of Jalisco.

Mexico: Jalisco: 9 mi NW Barra de Navidad, 17/IX/1971, 700´, A. Newton, (1).
 

The species was previously known from the states of Guerrero and Morelos, it has now been found in the state of Puebla as well.

Mexico: Puebla: Tepexco (near Izúcar de Matamoros), NTP-80, 7-25/V-VI/1989, A.C. Deloya, (43); Guerrero: Acahuizotla, VI-VII/1989, 650 m, NTP-80, bosque tropical mediano subperennifolio, L. Delgado, (37).

Ateuchus  illaesum (Harold), 1868

The species was previously recorded from the states of Chiapas, Hidalgo, Querétaro, San Luis Potosí and Veracruz in Mexico. There is a new state record for this species from Tamaulipas:

Mexico: Tamaulipas: Rancho El Cielo, Gómez Farías, 1-4/VII/1969, 3700', cloud forest, S. & J. Peck, (8).
 

Although this species was originally described from Guatemala, no precise location was given at the time. Here we give the first detailed localities for this country.

Guatemala: Escuintla: Finca Sta. Cecilia, 29/III/1991, M.E. González, (1); Guatemala: Sta. Catalina Pinula, Punta Parada, 20/II/1991, P. Broll, (1).
  ]]>

Ateuchus texanus (Robinson), 1948

The species is known from Texas, Tamaulipas, Nuevo León, Veracruz and San Luis Potosí. It is now recorded for the first time from the state of Querétaro.

Mexico: Querétaro: 20 mi W Xilitla, Rt. 120, 10-11/VI/1971, 5300', H. Howden, (6).
 

Final Remarks

From the scanty evidence of Ateuchus distribution in Mesoamerica, there seem to emerge certain patterns. A mountainous orofauna (a fauna developed in the area and representing its history) seems to occupy an area starting from southern Nicaragua to Costa Rica and Panama, with as yet not a precisely known southern limit (Kohlmann 1996-97). Another mountainous orofauna seems to be distributed from northern Nicaragua to Chiapas (A. chrysopyge, A. gershensoni, A. guatemalensis, A. perpusillus). The dry Pacific forests would represent another orofauna (A. rodriguezi). Wet Atlantic and Pacific forests have also their orofauna (A. howdeni, A. laetitiae, A. perezvelai), plus elements representing Amazonian invasions (A. aeneomicans, A.candezei). However, more information is still needed in order to clarify this situation.

Se incluyen mapas, ilustraciones del saco interno del edeago y fotografías del hábito dorsal, así como ilustraciones del hábito dorsal de las tres nuevas especies. Este estudio representa una extensión del trabajo originalmente realizado para los Ateuchus de Norteamérica (Kohlmann 1984). El trabajo clarifica la situación del género en Mesoamérica. También actualiza el conocimiento del grupo para México al reportar la presencia de cuatro especies más (dos nuevas, gershensoni y perezvelai; y dos nuevos registros para el país, chrysopyge y guatemalensis) y así incrementar el número de especies conocidas de ocho a doce.
