ABSTRACT

A taxonomic revision of the genus Scolia Fabricius, 1775 (Hymenoptera: Scoliidae) from Central America is presented. Two species of Scolia are present in Central America: S. (Discolia) guttata Burmeister, 1853 and S. (Hesperoscolia) rufiventris Fabricius, 1804, the latter representing the first record for Costa Rica, Panama and Colombia. The male of S. rufiventris is described and illustrated for the first time. Seasonal flight activity for S. guttata from two years of continuous Malaise trapping in Barro Colorado Island, Panama, is described.

Keywords: Scoliinae; seasonal flight activity; taxonomy; wasp

INTRODUCTION

Scolia Fabricius, 1775 is a cosmopolitan genus of fossorial solitary wasps in the subfamily Scoliinae presently containing 20 described species for America (Hanson, 2006). Scolia guttataBurmeister 1853 was the only described species recorded for Central America (Cameron, 1893).

Scoliid larvae are ectophagous idiobiont parasitoids of large Coleoptera larvae, including Sacarabaeidae, Passalidae, Lucanidae, and Curculionidae (Fernández, 2006; Kumar, 2009), for which they have been used as biological control agents (Clausen, 1978).

In this paper, we review the genus Scolia from Central America. Also, we present seasonal flight records for Scolia guttata on Barro Colorado Island, Panama.

MATERIALS AND METHODS

Flight seasonality data come from the field station of the Smithsonian Tropical Research Institute (STRI) on Barro Colorado Island (BCI), located in Gatun Lake of the Panama Canal, 9° 09'17" N; 79° 50' 53" W. The seasonal flight activity of Scolia guttata was studied by sampling specimens from ten Malaise traps (Townes modified) installed at ground level in the old forest by the Smithsonian Environmental Studies Program (see Richards and Windsor, 2007). The samples were collected weekly, from January 2005 to December 2006. For other information of the study area, see Windsor (1990) and Cambra et al. (2018).

Table 1 Total of Scolia guttata specimens collected by month in 16 years (1986-2001) in Costa Rica 

Distribution: U.S.A. (Arizona, Texas) to Venezuela (Cameron, 1893; MacKay, 1987; Maes, 1989) (Fig. 3).

Figure 3 Distribution of Scolia guttata and Scolia rufiventris in America. 

Comments: From Costa Rica (years 1986 to 2001) we examined 154 specimens (98 males and 56 females) of S, guttata; the specimens were collected mostly with hand nets during November (33 males /11 females), August (19 / 17) and October (18/ 4), the three months with greatest numbers of specimens captured (102 specimens = 66.2 %). These data suggest that adults of S, guttata are present in all months of the year. However, this information gives an inadequate indication of flight seasonality because the data were not collected with equal effort across the year.

Distribution: Mexico (without other data) (Saussure, 1858), Costa Rica, Panama, Colombia (First records), Guyana, Peru, Brazil (Mato Grosso and Minas Gerais) (Fabricius, 1804; Saussure, 1858; Fox, 1896; Dos Santos et al., 2015) (Fig. 3).

Comments: The two species of Scolia present in Central America, S. guttata and S. rufiventris, are differentiated by the diagnostic morphological characters presented above. Fernández and Cubillos, (1999) examined specimens of Scolia sp. 1 from Costa Rica (INBio) and Colombia (Antioquia, Cali, Valle, Dagua) and gave a brief description of Scolia sp. 1 that agrees with the description of Scolia rufiventris. Considerable effort was made to locate specimens collected from Colombia without positive results. Existing evidence (morphology and distribution) indicates that the specimens mentioned by Fernández and Cubillos (1999) are S. rufiventris.

Seasonal flight activity for Scolia guttata from Barro Colorado Island, Panama

During the two continuous sampling years (2005-2006) in BCI, 144 specimens of Scolia guttata (137 males and seven females) were collected, 106 individuals during 2005, 38 individuals in 2006. Collections peaked during June with 127 specimens (88.2 %), the remainder captured during May, July, and December (Fig. 4). All seven females from BCI were captured in June. No S, rufventris were recovered from the same BCI trap samples. The much smaller catch of S, guttata females relative to that of males in BCI could be the result of sampling methodology. Female Scoliidae typically spends a long time in the ground digging for larval hosts. For this reason, they are seldom collected with Malaise traps. However, males spend more time flying, mainly in search of females, thereby increasing chances of capture by Malaise traps. The under-representation of females in Malaise traps is not seen in the hand net collections from Costa Rica (INBio) where we had 56 females and 98 males of S, guttata.

Figure 4 Total of Scolia guttata specimens captured by month in two years (2005-2006) with ten Malaise traps in BCI. 

The hosts of S, guttata and other Scolia species in the Neotropical region remain unknown. However, the hosts of some Nearctic Scolia species have been reported. Rau and Rau (1918) recorded Cotinisnitida? (L., 1758) (Scarabaeidae: Cetoninae) as a host of S. dubia dubia Say 1837, and Ryckman (1956) reported a larva of Scarabaeidae as the host of S. nobilitata otomitaSaussure, 1858. The greater abundance of S. guttata in BCI during June may be related to a greater abundance of scarabaeid larvae present in the soil and available to be parasitized during the early wet season. Ratcliffe, (2003) notes the abundance of some Dynastinae scarab beetles on BCI is greater in May, June and July (E.g. Cyclocephala species). Further biological and abiotic information is necessary to better correlate flight seasonality and annual abundance of S. guttata in BCI.

ACKNOWLEDGMENT

We thank Lars Vilhelmsen, ZMUC, for photos of the lectotype specimen Scolia rufiventris, and their data labels; Gilberto De La Guardia for the donation of the specimen.
