Brachoria eutypa ethotela Chamberlin, new combination 



Figure oh-j 

 Brachoria ethotela Chamberlin, Bull. Univ. Utah, biol. ser., vol. 6, no. 8, p. 5, 

 fig. 13, 1942. 



Diagnosis: Distinguished from all other species of the genus except 

 hansonia, plecta, and separanda by the medium size and slender, 

 simple form of the gonopods. Differs from hansonia and separanda 

 in that the distal end of the telopodite of the gonopod is somewhat 

 swollen, with a hook-shaped end. Differs from separanda and plecta 

 in that the portion of the telopodite just distal to the cingulum is not 

 noticeably larger than the portion just proximal to the cingulum. 

 Distinguished from eutypa eutypa by the presence of a swelling just 

 proximal to the distal end of the telopodite. 



Description: Length of holotype, not given; width, 9 mm.; length 

 of other male specimens, 37-41 mm.; width, 8-10 mm.; length of 

 female, 41 mm.; width, 9 mm. 



Collum ellipsoidal, edges gently curved, ends of paranota broadly 

 rounded; paranotal swellings extremely weak or absent; no ridges 

 extending along cephalic edges of paranota. 



Paranotal swellings either extremely weak or absent on segments 

 2 and 3, very slightly stronger on segment 4, never very strong on 

 any segment. Paranota of segments 2-7 gently rounded; those of 

 succeeding segments, including 9th, more abruptly rounded; paranota 

 of segments 16, 17, and 18 not very sharply triangular. 



Sterna of 3d and 4th pairs of legs with well-developed processes; 

 sternum of 5th legs with pair of weak processes; sternum of 6th legs 

 ridged in some specimens, smooth in others. 



Ai-mature of prefemora of postgenital legs not quite as strong as 

 in initialis. Coxal armature of males weak to moderate. 



Male gonopods of medium size (about 2.03 mm. in telopodite arc 

 length and 2.12 mm. in arc width) ; sunple; cm'ved mesiad, then dorsad 

 in continuous^:ai-c ; extreme distal end bent to hook-like appearance; a 

 noticeable swelling just proximal to distal end; cingulum located at 

 point on arc just proximal to point most remote from body; pre- 

 cingular portion slightly longer than postcingidar portion. Pre- 

 femoral spine moderate. 



Color very dark brown above and on preanal scale; bright yellow 

 on caudolateral portion of all paranota, including collum; a small 

 median yellow spot on anterior margin of collum; distal half of last 

 tergite yellow; underparts and legs light brown; antennae dark brown, 

 last three joints darkest. 



Type locality: Marion, Smyth County, Va. 



Type specimen: In the private collection of R. V. Chamberlin.
