CORIMELAENIDAE Uhler (including THYREOCO- RINAE Amyot and Serville)

Historical: This family-group taxon, as conceived by many authors, includes 12 genera distributed in the

Eastern and Western Hemispheres. McAtee and Malloch (1933) revised the nine American genera; Dolling (1981) proposed maintaining the three Palearc-

tic genera Thyreocoris Schrank , Strombosoma Amyot and Serville , and Carrabas Distant in the subfamily Thyreocorinae Amyot and Serville , removing all the American genera to the subfamily Corimelaeninae

Uhler, but including both under the Cydnidae (see Rolston and McDonald, 1979, concerning the correct name for the family). Gapud (1991) stated that the Thyreocorinae (= Corimelaeninae sensu Dolling, 1981 ) is related to the Cydnidae by the presence of coxal fringes (character 261) and tibial spines (character 271), a conclusion supported in our morphological analyses. A deeply sulcate and strongly carinate prosternum (characters 231, 241) is found in the Corimelaenidae (including Thyreocorinae ) but also occurs in the Scutelleridae , Canopidae , and Megarididae .

Analytical result: The Corimelaenidae , as represented by Allocoris and Thyreocoris , is treated in our morphological analyses under successive weightings ( Fig. 43 View Fig ) and PIWE ( Fig. 44 View Fig ) as the basal group within the Cydnidae , being paraphyletic in the former. Combined molecular analyses treat Allocoris as either the sister group of the Parastrachiinae (1: 1 cost ratio; Fig. 45 View Figs 45–48. 45 ) or the sister group of all remaining taxa distal to the Parastrachiinae on the cladogram (2: 2 cost ratio; Fig. 46 View Figs 45–48. 45 ). Allocoris maintains an association with the Parastrachiinae in the 52-taxon total evidence analysis under both 1: 1 and 2: 2 cost ratios ( Figs 51 and 52 View Figs 49–52. 49 , respectively), but also including Cydninae sp. 1 in the former. The results of the 92-taxon analysis are similar ( Figs 53–55 View Fig View Fig View Fig ). The characters supporting this grouping are the posterior and humeral pronatal angles not developed (150), the coxae with fringes of setae (261), and the foretibiae with a row of stout setae on the lateral margin (271). The last two of these are the same as characters that support the monophyly of a broadly conceived Cydnidae (as recognized by Dolling, 1981) in our morphological analyses. Some of our analyses also associate Sehirus with either Corimelaenidae sensu stricto, or Parastrachiinae, or both, on the basis of the same characters listed above for Corimelaeninae + Parastrachiinae. In the absence of a stronger sequence data set, we are inclined to maintain the family status of the Corimelaenidae and incorporate the Parastrachiinae, the latter of which we treat at subfamily status.
