Abstract. The name Isophya tatrica Mařan, 1957, was used by D

OBŠÍK

 (1959) 

in the series ‘Key to the fauna of Czechoslovakia’ but the species has never been 

properly described and the name must be considered as nomen nudum. Based on 

the study of material deposited in the National Museum in Praha and designated by 

Mařan as the holotypus and allotypus of I. tatrica, we confi rm his later assumption 

(M

AŘAN

 1958) that the specimens belong to I. camptoxypha Fieber, 1853.

In the years 1954-1958, Josef Mařan (National Museum, Praha) revised numerous spe-

cimens of the genus Isophya Brunner von Wattenwyl, 1878, from Slovakia and recognised 

several unknown species. One of them was a small species from the Vysoké Tatry (= High 

Tatras) Mts., provisionally

 

named Isophya tatrica. However, its valid description has never 

been published unlike the descriptions of I. pienensis Mařan, 1954 (M

AŘAN

 1954) and I. 

beybienkoi Mařan, 1958 (M

AŘAN

 1958). Later on, he wrote about I. tatrica that ‘the unknown 

species from the High Tatras and the High Fatra can be identifi ed as I. brevipennis’ (M

AŘAN

 

1958). Isophya brevipennis Brunner von Wattenwyl, 1878, is currently a synonym of I. cam-

ptoxypha Fieber, 1853.

In the following year, the third volume of the series ‘Key to the fauna of Czechoslovakia’ 

was published, including the key to Orthoptera (D

OBŠÍK

 1959). D

OBŠÍK

 (1959) presented I. 

tatrica as a valid species, even with the year of description (as I. tatrica Mařan, 1957) but 

without any detailed comments. Since that time, no other reference to this name has been 

published and the specimens labelled as I. tatrica by Mařan have not been studied (see H

ELLER

 

et al. 1998, 2004; K

OČÁREK

 et al. 2005). 

We have had the opportunity to study specimens associated with this name and resolve 

their identity.

Material examined. SLOVAKIA: Vysoké Tatry Mts., Vyšné Hagy (6887), ca 1150 m a.s.l., vii.1956,  , Moucha 

leg., labelled as holotype of I. tatrica, Mařan det, coll. National Museum in Praha. Measurements: body 18.2 mm 

long, hind femur 14.3 mm long, tegmen 4.2 mm long, 79 stridulatory pegs. SLOVAKIA: Vysoké Tatry Mts., Vyšné 

Hagy (6887), ca 1100 m a.s.l., vii.1956,  , Moucha leg., labelled as allotype of I. tatrica, Mařan det, coll. National 

Museum in Praha. Measurements: body (without ovipositor) 16.0 mm long, ovipositor 8.1 mm long, hind femur 

15.8 mm long; tegmen 1.7 mm long.

One of the most reliable identifi cation features, i.e. the number of pegs on the stridulatory 

fi le (H

ELLER

 et al. 2004), was not known in the 1950s (cf. M

AŘAN

 1958). Based on the structure 

of the stridulatory fi le, the shape of the male cerci and the length and shape of the tegmen and 

ovipositor, the studied specimens can be clearly identifi ed as I. camptoxypha.
