Gallobelgicus Distant 1906

Overview & Synopsis

Gallobelgicus Distant, 1906Type species: Gallobelgicus typicus Distant, 1906. By monotypy, six species included.The genus has been characterized by the clypeus armed with an anteriorly directed spine; head, first visible labial segment, procoxa, protrochanter, profemur, and protibia with large spiniform setae; humeral angles with long spines; and the first tarsal segment subequal to the lengths of the remaining segments combined (Rédei and Tsai 2010). Currently, Gallobelgicus consists of six species occurring in the Oriental region. Unfortunately, the type species was not included in our data matrix due to the lack of available specimens. Based on the paramere shape, Miller (1957) proposed a ‘ Gallobelgicus complex’ for the genera Gallobelgicus, Choreutocoris Miller, 1957, and Panagrocoris Miller, 1957. However, this grouping was not recovered in our phylogenetic hypothesis. On the other hand, Pristicoris has been previously related to Gallobelgicus (Miller, 1952, Rédei and Tsai, 2009), and our results are consistent with this hypothesis. However, we think that the missing data of the matrix (particularly of genitalic characters) have an important effect in the analysis and resulted in the recovery of Gallobelgicus as paraphyletic. All Gallobelgicus specimens included in the analysis are males, whereas in the case of Pristicoris the specimen studied is a female. It is probable that the inclusion of additional male and female specimens for both genera will help to solve their relationship.Examined material: Gallobelgicus heissi Rédei and Tsai, 2009: one male, THAILAND: Chiang Mai prov., 20 km SW of FANG, 19°49’57 ʹʹ N 99°02’54 ʹʹ E, 11.i. 2006, 1450 m, Lgt.
