status

 

Afroeudesis subgen. Eudesoides, Archiconnus, Euconnomorphus, Euconnus, Napoconnus, Plaumanniola, Sibylloconnus, Tridensius, and Venezolanoconnus. These genera can be identified using the following key: 

3. Anterior portion of mesoventral process with pair of sublateral arms curved anterad, forming trident-like structure; frons in dorsal view anteriorly emarginate; adcoxal part of prothoracic hypomeron (mesad hypomeral ridge) divided into narrow anterior and subtriangular posterior portions............................................................... Tridensius 

- Mesoventral process lacking anterior trident-like structure; frons not anteriorly emarginate; adcoxal part of hypomeron not divided.............................................................................................. 4

4. Prothoracic hypomera anteriorly strongly expanded mesad, so that anterior margin of prosternum is only half as long as posterior margin................................................................................ Sibylloconnus 

-. Hypomera anteriorly not strongly expanded mesad, so that anterior margin of prosternum is comparably long as posterior margin or only slightly shorter............................................................................... 5

5. Metacoxae narrowly separated by pair of long pointed spines directed posterad.................................... 6

- Metacoxae contiguous or separated by metaventral process lacking pair of spines................................... 7

6. Antennae gradually thickened; parameres modified, in lateral view their proximal half or more as broad as median lobe.......................................................................................... Venezolanoconnus 

- Antennae with sharply delimited club; parameres unmodified, slender, rod-like........................... Napoconnus 

7. Maxillary palpomere III conspicuously broadened, at most twice as long as broad and broader than 1/3 width of head; metacoxae contiguous............................................................................ Archiconnus 

- Maxillary palpomere III not conspicuously broadened, more than twice as long as broad and not broader than 1/3 width of head; metacoxae at least narrowly (but often broadly) separated..................................................... 8

8. Basisternum much shorter than procoxal rests, often vestigial; frontoclypeal groove present; parameres unmodified, slender and rod-like...................................................................................... Euconnus 

- Basisternum about as long as procoxal rests; frontoclypeal groove absent; parameres modified, in lateral view their proximal 3/4 or more as broad as median lobe, only short apical regions slender............................... Euconnomorphus
