Key to species of Sakakibarella :

1. Male ( S. costaricensis , S. seminigra , S. crassa sp. nov. are known only from males).................................2

1’. Female ( S. elongata , S. sinuosa are known only from females).................................................. 6

2 (1). Pronotum with antero-dorsal process distinct, acutely angled, as long as or longer than wide in lateral view ( Figs. 1–4 , 14–17 ).................................................................................................... 3

2’. Pronotum convex, dorsal outline slightly protuberant, obtusely angled, distinctly shorter than wide in lateral view ( Figs. 5–6 , 18–19 )..............................................................................................4

3 (2). Antero-dorsal pronotal process large, length approximately equal to metopidium height; general coloration brown, lacking distinct darker markings on pronotum; forewings translucent ( Figs. 1 , 14 , 22 )................... costaricensis Creão-Duarte

3’. Antero-dorsal pronotal process small, length approximately half metopidium height; general coloration light brown, with a large dark brown patch covering almost entire metopidium, between humeral angles and dorsal process; forewings slightly smoky ( Figs. 3 , 16 , 24 )............................................................... seminigra Creão-Duarte

4 (2’). In lateral view, dorsal outline of pronotum distinctly sinuous, with a depression between humeral angles and posterior process ( Figs. 8 , 13 , 21 , 29 )................................................................... santaceciliae sp. nov.

4’. In lateral view, dorsal outline of pronotum descending in a straight diagonal line from base of antero-dorsal process to apex of posterior process ( Figs. 14–19 )........................................................................... 5

5 (4’). Pronotum lacking antero-dorsal process; general coloration black or dark brown, pronotum mottled with light brown spots; forewing membrane smoky; legs light brown ( Figs. 5 , 10 , 18 , 26 ).................................... albinoi sp. nov.

5’. Pronotal antero-dorsal process consisting of small protuberance; general coloration light brown, with dark marks on metopidium, transversally extending between humeral angles and antero-dorsal protuberance; forewings hyaline ( Figs. 6 , 11 , 19 , 27 ).......................................................................................... crassa sp. nov.

6(1’). Pronotal dorsum distinctly sinuous, with a depression between humeral angles and posterior process ( Figs. 20-21 )........ 7

6’. Pronotal dorsum descending in somewhat straight diagonal line from base of dorsal process to apex of posterior process.... 8

7(6). Apex of antero-dorsal pronotal process strongly truncate, dorsal margin dark; posterior process with a dark patch ( Figs. 7, 8 , 12, 13 , 20, 21 , 28, 29 )................................................................. santaceciliae sp. nov.

7’ Apex of antero-dorsal pronotal process round, with discrete dark mark extending between tip and humeral angles............................................................................................ S. sinuosa Creão-Duarte

8(6’). Antero-dorsal process distinctly longer than wide; mostly light brown, lacking dark markings ( Fig. 15 )................................................................................................... S. elongata Creão-Duarte

8’. Antero-dorsal process slightly longer than wide; mostly brown, mottled light brown; metopidium, anterior process and anterior region of dorsum darker than rest of pronotum ( Fig. 17 )......................................... S. albinoi sp. nov.
