Tonatia nicaraguae Goodwin, 1942

_Specimens._--_Boaco_: Santa Rosa, 17 km N, 15 km E Boaco, 300 m,

1. _Chontales_: Hato Grande, 13 km S, 8 km W Juigalpa, 60 m, 1.

Only four specimens of this seemingly rare species have been recorded

previously from Nicaragua--one (the holotype) from Kanawa Creek, near

Cukra, north of Bluefields, 100 ft, Zelaya (Goodwin, 1942b:205),

another from 12.5 mi. S and 13 mi. E Rivas, 125 ft, Rivas (Davis and

Carter, 1962:67-68), and two from 6 km N Tuma, 500 m, Matagalpa (Valdez

and LaVal, 1971:248). Our specimens were caught in mist nets placed

over small, quiet streams that were fringed with tall, gallery forest.

The surrounding areas were savanna-like with small stands of secondary

forest. An adult male taken on 21 April had testes that measured 5 mm

in length, whereas those of another (9 August) were 3 mm.

Handley (1966b:761) synonymized _T. nicaraguae_ with _Tonatia minuta_

Goodwin, 1942, a conclusion with which we agree. However, the name

_nicaraguae_ (Goodwin, 1942b:205) has page priority over _minuta_

Goodwin (op. cit.:206) and is the valid name for the species rather

than _minuta_ as used by Handley (see also LaVal, 1969:820; Gardner

_et al._, 1970:716; Valdez and LaVal, 1971:248).

Measurements of the two males (that from Hato Grande listed first) are

as follows: total length, 63, 60 mm; length of tail, 5, 6 mm; length of

hind foot, 10, 9 mm; length of ear, 23, 23 mm; length of forearm, 34.5,

35.6 mm; weight, 11.4, 8.8 gms; greatest length of skull, 20.2, 20.5

mm; zygomatic breadth, 9.5, 9.5 mm; breadth of braincase, 8.5, 8.2 mm;

postorbital breadth, 3.1, 2.9 mm; length of maxillary toothrow, 7.0,

7.1 mm; breadth across upper molars, 6.3, 6.5 mm. We have not compared

our specimens directly with others from Middle America. On the basis of

available measurements, they resemble material reported from Honduras

(LaVal, 1969:820), averaging larger than other specimens for which

measurements have been published (see especially Goodwin, 1942b:206;

Davis and Carter, 1962:68; Davis _et al._, 1964:379; Gardner _et al._,

1970:716-717).
