NO. 3B4S ARADIDAE — KORMILEV 13 



Abdomen as long as width across segment IV (42 :42.5). Tergum I 

 completely fused wdth metanotum (median, triangular plate), and 

 with tergum II ; latter can be recognized only because it is at a slightly 

 lower level. Central dorsal plate of the abdomen consists of terga 



III to VI, with a slightly elevated median line narrowed on tergum 

 III, much wider on terga IV and V, and with a double longitudmal 

 carina on tergum VI ; laterad of the median elevation disc has a pattern 

 of irregular rugae and round callous spots. Tergum VII convex 

 medially, sloping laterally; VIII very short and wide. Connexivum 

 wide; discs of connexival segments with a pattern of rough rugae and 

 granules; exterior borders of each segment slightly convex, entire 

 lateral border weakly festooned; postero-exterior angles from II to 



IV not protruding, V slightly protruding, VI forming an obtuse angle, 

 and VII forming a right angle. Paratergites rounded, produced 

 backward beyond tip of very short segment IX. Spiracles II to 

 VIII lateral, visible from above. 



Color. — Brown; lateral borders and central dorsal plate of the 

 abdomen partially mottled with black. 



Measurements. — Total length 3.24 mm.; width of pronotum 1.12 

 mm.; width of abdomen 1.56 mm. 



HoLOTYPE. — Female, Cayamas, Cuba; deposited in the Drake 

 coUection (USNM type 67587). 



Kolpodaptera rugosa, new species, is related to K. prominens Usinger 

 and Matsuda and may be separated from it mainly by head shorter 

 than width across the eyes; antennae relatively longer, more than 

 twice as long as the head (less than twice in K. prominens) ; and 

 different proportions of the antennal segments which are 20:10:14:15, 

 whereas in K. prominens they are 25:11:16:17. 



Subfamily Merizinae Oshanin, 1908 



Mezirinae is the largest subfamily of the Aradidae. Previously, it 

 was considered as a family under the name of Dysodiidae Renter, but, 

 as Usinger and Matsuda pointed out (1959, p. 54), that would distort 

 the actual relationship between subfamilies so far included in Dyso- 

 diidae; therefore, they accepted Aradidae as a single family, consisting 

 of eight subfamilies, including Mezirinae, and leaving only Termita- 

 phididae as a second family in the superfamily Aradoidea. 



Mezirinae has an almost worldwide distribution. It is absent from 

 the frigid areas and develops the highest number of genera and species 

 in the tropical and subtropical zones. Strange as it may seem, from 

 the entire European and Siberian part of the Palaearctic region there 

 is recorded only a single species of Mezirinae, Mezira tremulae 

 (Germar) , 1822. The Manchurian subregion of the Palaearctic region 

 contains several genera and numerous species.
