another. They do share some features with certain members of that 
large aggregate, but can be grouped together and distinguished from 
other lycosids on the basis of characteristics delineated in the 
preliminary diagnosis of the genus and the discussion of species 
groups. 
Trochosa C. L. Koch 
Trochosa C. L. Koch, 1848: 95; 1851: 33. Type species by original designation Arenea 
ruricola DeGeer, 1778. Keyserling 1877: 610. Scudder 1882: 328. Marx 1890: 564. 
McCook 1894: 90, 100, 107, 112, 118. Montgomery 1904: 300. Banks 1905: 319. 
Petrunkevitch 1928: 250. 
Trochosina Simon, 1885: 10 (subgenus of Trochosa). Type species by original desig¬ 
nation Trochosa terricola Thorell, 1856. Roewer 1954: 302 (raised to generic 
status). 
Varacosa Chamberlin and Ivie, 1942: 36 (subgenus of Trochosa). Type species by 
original designation Trochosa avara Keyserling, 1877. Roewer 1954: 304 (raised 
to generic status), new synonymy. 
Allohogna (part). Roewer, 1954: 212. 
Allotrochosina Roewer, 1954: 213. Type species by monotypy. Lycosa maunganui- 
ensis Berland, 1925 (misspelled mananganuiensis by Roewer). 
Diahogna Roewer, 1954: 239. Type species by monotypy Lycosa martensii Karsch, 
1878. 
Trochosomma Roewer, 1954: 304. Type species by original designation Trochosa 
annulipes L. Koch, 1875. 
Discussion. For a more complete listing of synonyms of Trochosa 
by European authors refer to Bonnet (1959: 4698-4699). Trochosina 
Simon, Allotrochosina Roewer, and Diahogna Roewer were syn- 
onymized by Guy (1966) and his findings are supported here. Tro¬ 
chosomma Roewer was synonymized by McKay (1979). 
Characteristics. Small to medium size spiders (total length 5.8 to 
13.0 mm). Carapace length 3.2 to 5.9 mm; width 2.4 to 4.3 mm. 
Color brownish yellow to dark brown with a lighter submarginal 
stripe on each side of the carapace and a broad median light stripe 
as in Figures 1-6. Within the light median stripe appears a pair of 
dark short stripes or dashes as in Figures 1, 2, 3, 5, 6. Trochosa 
gosiuta (Fig. 4) is the only species that does not show these dashes so 
characteristic of the genus. With this exception the dorsal pattern is 
similar throughout the genus. Abdomen yellowish brown to brown 
ground color with darker brown or black markings; sometimes with 
indistinct chevrons, but mostly mottled as in Figures 1-6. 
Eyes: Anterior median eyes (AME) larger than anterior lateral 
eyes (ALE). Posterior median eyes (PME) larger than posterior
