Abstract. — Kerzhnercryptes perinetus, n. gen., n. sp., from Madagascar are described 
in the tribe Daladerini (Coreidae). A habitus view illustration and drawings of the anten- 
nae, pronotum, legs, abdomen, and male and female genitalia are provided. A key to the 
known genera of Daladerini from Madagascar is included. 
Key Words: Insecta, Heteroptera, Coreidae, Daladerini, new genus, new species, Mad-

The Coreidae fauna of Madagascar is 
rich and diverse but has been studied little 
by modern workers. The tribe Daladerini at 
present is composed of 8 genera and 28 
nominal species distributed throughout the 
Old World tropics, with the majority of spe- 
cies and the greatest diversity in southern 
Africa. 
The Madagascar Daladerini have never 
been revised. The first species recorded was 
by Stal (1873), who described a new genus 
and one new species, Odontorhopala cal- 
losa. Distant (1879) studied the Madagascar 
Hemiptera and added one new genus, Par- 
abrachytes, with two new species, P. co- 
loratus and P. obscurus, and later Distant 
(1893) described Odontorhopala bergrothi 
and discussed the generic position of Odon- 
torhopala and Parabrachytes. Bergroth 
(1906) described a new genus and one new 
species, Rhombolaparus tardigradus, and 
later Bergroth (1912) added the new spe- 
cies, Odontorhopala geminata. Garcia Var- 
ela (1913) described Parabrachytes longi- 
cornis and gave new distribution records 
for Odontorhopala callosa and Parabrach- 
ytes coloratus. 
Here I add a new genus and a new spe- 
cies in order to make the name available for 
discussion of the zoogeography of the tribe.

Kerzhnercryptes Brailovsky, new genus 
Diagnosis. — This genus appears to be 
closely related to Parabrachytes Distant 
(1879) particularly due to the relatively nar- 
row, non-expanded abdomen (Fig. 9), and 
the humeral angles of the pronotum not 
conspicuously expanded as a wing-like 
lobes (Figs. 7-8). Kerzhnercryptes has an- 
tennal segment 11 almost cylindrical without 
distal spines (Fig. 1), the rostrum elongate, 
slender and reaching abdominal sternite III, 
each femur slender and armed ventrally 
with two small subapical spines (Fig. 16), 
the humeral angles of the pronotum sub- 
acute (Fig. 7), and the tibiae longer, and 
more slender. Parabrachytes is distin- 
guished by having antennal segment II dis- 
tally clavate and armed with strong spines 
(Fig. 3), the rostrum short, robust and not 
extending beyond the middle third of the 
mesostemum, the femora robust and ven- 
trally armed with two rows of stout spines 
(Fig. 5), the humeral angles rounded, and 
obtuse (Fig. 8), and the tibiae short, and 
robust. 
Rhombolaparus Bergroth (1906) is clear- 
ly distinguished by having the abdomen 
conspicuosly dilated, rhomboidal, and the 
humeral angles of pronotum laterally ex- 
panded. 
Generic description. — Body medium 
sized to large, moderately elongate. Head: 
Across eyes wider than long, subquadrate, 
dorsally flat; tylus conspicuously deflexed,

peziform, moderately declivent; collar not 
distinctly marked; anterolateral margins

finely nodulose (Fig. 7); posterolateral mar- 
gin sinuate, with upper half nodulose and 
inner half smooth; posterior margin smooth, 
concave; callar region indistinct, transverse- 
ly flat, separated along midline by an ob- 
scure longitudinal groove; posterior margin 
with transverse ridge, distinctly raised; 
prosternum with deep excavation; meso-

groove; metasternum entire; anterior lobe of 
metathoracic peritreme elevated, reniform, 
posterior lobe sharp, small. 
Legs: Femora slightly incrassate, surface 
smooth, armed with two small anteapical 
spines; tibiae cylindrical, sulcate, unarmed. 
Scutellum: Triangular, flat, relation 
length-width, with two conditions indepen- 
dent of the sex, longer than wide, or wider 
than long, and transversely striated; apex 
short, acute. 
Hemelytra: Macropterous, reaching apex 
of last abdominal segment; costal margin 
with a shallow groove; apical margin 
obliquely straight, with short apical angle 
almost reaching middle third of hemelytral 
membrane. 
Abdomen: Connexival segments higher 
than margin of hemelytron at rest; upper 
margin smooth; posterior angles simple, not 
spinose; posterior third of connexival seg- 
ments III, IV and VII straight, and posterior 
third of segments V and VI depressed, con- 
cave or diagonally truncated; abdominal 
spiracle closer to anterior margin than to 
posterior margin.
