AbstractRostromyrmex, a new genus of myrmicine ants from Peninsular Malaysia is described on the basis of workers, dealate females, and a single male. Analysis of characters suggests a closest relationship with either Lordomyrma or the Solenopsis genus group.

Field Behaviour

The entomology of swollen shoot of cacao is a complex and unique problem involving the inter-relations in the field of over 120 insect species of four insect and two arachnoid orders. Briefly, there are 17 species of pseudococcids, 75 species of ants, 16 species of hymenopterous parasites, three predatory beetles, one predatory dipteran, and three arachnid species involved in vector relationships directly, with a further 18 Coccid species involved indirectly (it is possible, of course, that further work will show that some of these 18 species are directly concerned as vectors).In the present paper an attempt has been made to reduce this assemblage of insect material to some semblance of order. The Coccid species are named and a series of preliminary observations on their biology and field behaviour detailed. The ant species, some of which are obligatorily associated with certain vector species, have been sorted into groups where specific determination has proved impossible or unnecessary and information has been included on their field habits and relative abundance.There are three distinct but complementary ecological niches involved in the problem. The first, and most important, is the association between the mealybug virus vectors and the Myrmicine coccid-tending ants. The second is the association between mealybugs of the genera Paraputo and Formicococcus and the wild forest tree hosts of swollen shoot virus, and the third is the negative association between the mealybug tending Myrmicine ants and Oecophylla and Macromischoides, the latter species acting in certain circumstances as barriers to the spread of the mealybugtending species and hence to the spread of mealybugs and virus. These problems will be dealt with on a quantitative basis in a further paper.

Myrmicine Ants

The myrmicine ant genus Cardiocondyla is characterized by a peculiar male diphenism with winged disperser males and wingless, “ergatoid” fighter males. Here we describe and illustrate the morphology of the male external genitalia of 13 species of this genus. Several characters, especially the parossiculus of the volsella and the medial face of the paramere, vary between different species groups and might be useful to clarify the infrageneric taxonomy of Cardiocondyla. External genitalia between different phenotypes of a species differ primarily in size. All examined males, both winged and ergatoid, have a parameral hook that resembles a structure described in Nesomyrmex males but apparently is absent in other studied myrmicine ants. The presence and absence of this hook might be useful for future studies on the relationships within the myrmicine tribe Crematogastrini.

Myrmicine Ants

A revision of the myrmicinae ants of the Adelomyrmex genus-group is made. This group is recognized in workers and females by a combination of: antennae of 12 segments with club of 2 segments, median portion of clypeus forming a longitudinal platform and the lamelliform setae in the internal border of the mandibles. This last trait, unknown in other ants, is proposed as autapomorphy for the Adelomyrmex genus-group. The group contains two genera, Adelomyrmex Emery , 1897 (Neotropics, New Guinea, Fiji, Samoa) and Baracidris Bolton, 1981 (Africa), with 26 species (12 described as new) as follows: Adelomyrmex betoi Fernández sp.n. (México); A. biroi Emery, 1897 (New Guinea), A. boltoni Fernández sp.n. (Brazil and Paraguay); A. brevispinosus Fernández, 2003 (México and Costa Rica); A. costatus Fernández sp.n. (Colombia); A. cristiani Fernández sp.n. (Colombia); A. foveolatus Fernández, 2003 (Costa Rica); A. grandis Fernández sp.n. (Colombia); A. hirsutus Mann, 1921 (Fiji Islands); A. laevigatus MacKay, 2003 (Costa Rica); A. longinodus Fernández & Brandão sp.n. (Brazil); A. longinoi Fernández sp.n. (México and Costa Rica); A. mackayi Fernández sp.n. (México); A. micans Fernández, 2003 (México); A. microps Fernández, 2003 (Costa Rica); A. minimus Fernández, 2003 (Costa Rica); A. myops (Wheeler, 1910) (Guatemala to Colombia); A. robustus Fernández sp.n. (México); A. samoanus Wilson & Taylor, 1967 (Samoa); A. silvestrii (Menozzi, 1931) (Mesoamerica); A. striatus Fernández sp.n. (Brazil); A. tristani (Menozzi, 1931) (México to Colombia); A. vaderi Fernández sp.n. (Colombia); Baracidris meketra Bolton, 1981 (Nigeria), B. pilosa Fernández sp.n. (Kenya and Gabon); B. sitra Bolton, 1981 (Gabon). A key to workers of genera and all species is provided, with illustrations of most of them. The first queen for American Adelomyrmex and the first male of Adelomyrmex are described. The distribution of the group suggests an ancestor that lived in Gondwana before the splitting off of Africa and also suggests that ants could have originated earlier than the known fossil record.

Myrmicine Ants

The taxonomy of the myrmicine ants of the Aphaenogaster testaceopilosa-group is revised. Fourteen species are recognized, including two new species, both from Greece: A. balcanicoides sp. n. and A. karpathica sp. n. Aphaenogaster melitensis Emery, 1924 and A. sporadis Santschi, 1933 are elevated to species level. The following new synonyms are established: Aphaenogaster ionia Santschi, 1933 (= A. balcanica Emery, 1898), A. senilis grata Santschi, 1933 (= A. senilis Mayr, 1853), A. senilis occidua Santschi, 1933 (= A. senilis), A. spinosa etrusca Baroni Urbani, 1969 (= A. spinosa Emery, 1878) and A. corsica Casevitz-Weulersse, 2010 (= A. spinosa). Furthermore, a redescription is given for all European species of the Aphaenogaster testaceopilosa-group. The genus Aphaenogaster now includes 178 species, of which 36 are known from Europe. Identification keys are provided.
