* Diphrontis cruenta Gerstaecher, 1883

( Fig. 5i )

Distribution: CAM, EQG, GAB, GBI, GHA, NRE, RCI.

Distribution in Guinea-Bissau (Administrative Regions): 2) TOB.

Historic records: none.

Material examined: Coli (Quebo) (11º 37´01.63´´ N, 14º 46´13.80´´ W, 48m alt.) (TOB), 29.VI‒16.VII.2006, 1 ♂, CT, A. Serrano leg., ASC .

Remarks. The species presents a distribution throughout West Africa ( Beinhundner 2017b; Schoolmeesters 2019). The segregation between D. cruenta and D. trigrina (Kraatz, 1888) was provided by Antoine (1999). The Coli specimen fits very well the morphological characters given for this species by Antoine (1999), including the shape of parameres. This new record for Guinea-Bissau extends far away to north its distribution in Africa. The adult specimen from Coli was collected by CT ( Fig. 2b ) in an open secondary forest ( Fig. 2e ). See also the remarks under C. quadrisignata for this locality. Some biodiversity information (e.g. abundance, habitat preference, phenology) was provided for GHA by Mudge et al. (2012). It is a new genus/species record for Guinea-Bissau.
