NEOTROPICAL MALLOPIL\GA — CARRIKER 431 



but the tergites are more ^ndely separated mediallv; the stemites 

 also seem to be the same but they are quite impossible to distinguish 

 clearly in this genus due to the heavier pigmentation of the tergites. 

 The chaetotaxy of the last four abdominal segments in the male is 

 more abundant than in the female. 



Male genitalia resemble somewhat those of Formicaphagu-s in that 

 the basal plate is short and vride, the parameres are more or less 

 globular, but of quite different shape, and the detaUs of the mesosome 

 differ strongly in the five species represented by males. Unfortunately 

 the five species with male representatives are all from subspecies of 

 Formicarius analis. When males have been taken from the other 

 two species, colma and nigricapillu-s , they may show important dif- 

 ferences, although there are no striking differences between the females 

 of those species and females from the races of F. analis. 



Formicaricola analoides, new species 



FiGUBEs l,c; 7,d; 9,c 



Types: Male and female adults from Formicarius analis saturaius 

 Ridg^vay. collected by the author near Zaragoza, Antioquia, Colombia. 

 Mar. 22, 1948 (USXM). 



Diagnosis: This species, the type of the genus, has been quite 

 fully described under the generic characterization. The seven known 

 forms of the genus Formicaricola are very similar in general appear- 

 ance, differing from each other only in many small details, so that one 

 species may resemble several others in shape of head, but have the 

 anterior plate, the cephalic carinae, the thoracic segments or abdomi- 

 nal sclerites quite distinct. 



The present species resembles most closely the Costa Rican and 

 Mexican forms from Formicarius analis umbrosus and Formicarius 

 analis moniliger, but differs as follows: Head smaller than both, 

 wider at tips of marginal carinae and narrower at coni; premarginal 

 carinae and nodi differ in shape, as well as postmarginal carinae; 

 pterothorax smaller, with posterior margin straight on the two sides 

 as in cosfaricensis (concave in mexicana). Adbominal segment VII 

 in male same shape as in cosfafncensis, but different from mexicana, 

 \^'ith chaetotax%' of segment ^T^II different in aU three. The anterior 

 margin of segment ^111 in the female is convex in analoides and 

 concave in cosfaricensis (female of rnexicanus unkno^vn). 



The male genitalia of all three are s imil ar in type but differ in 

 detail, those of mexicana resembling more closely those of analoides. 



The species is represented by the male holotA-pe and female allo- 

 type, with other specimens from tvpe host collected at folloA\"ing 

 localities: Regeneracion. El Real, and Xorosi. Department of Bolivar.
